Printing and manufacturing method, transfer and decoration device and transfer jewelry

The present invention relates to a method for producing a transfer jewel which is applied by transfer on one surface of a decorative body, a transfer garnish, and a transfer jewel.

Products that are decorated on the surface of molded articles such as metal and resin are used in various fields such as automobiles, household electrical appliances, mobile phones, and personal computers. The decoration of the surface of the molded article is performed, for example, by bringing the transfer sheet having the transfer layer into contact with the surface of the molded article to transfer the transfer layer. However, in the case where the surface shape of the transferred molded article is a three-dimensional shape, in order to bring the transfer sheet into contact along the surface of the molded article, for example, compressed air forming as shown in Patent Document 1 may be used (air- Pressure forming) device.

[Patent Document 1] Japanese Patent Laid-Open Publication No. 2002-79573

When the metal body as the object to be decorated is subjected to transfer and decoration, if the pressure of pressing the transfer sheet against the metal body is not so large, the transfer layer cannot be in close contact with the surface of the metal body. Further, when the surface of the decorative body has a three-dimensional shape such as a deep shape, even if a compressed air forming device is used, it is difficult to apply uniform and sufficient pressure so that the transfer sheet is uniformly attached to the decorated article. The surface of the body, and in order to give the necessary pressure, the equipment itself has become very large. In addition, there is a technique of adding a composite having a surface in which a metal portion and a molded resin portion are continuous (Japanese Patent Application No. 2009-272836, see Fig. 7). The product manufactured by the technique is a molded resin portion having a metal portion having an opening, integrated on the back side of the metal portion to fill the opening, and a molded resin portion continuously formed on the surface and the opening portion of the metal portion. The surface of the transfer layer is formed. In this manufacturing method, the transfer sheet and the metal portion are placed at predetermined positions in the injection molding die to eject the molten resin to the cavity, thereby simultaneously performing the injection molding of the molding resin portion and the application of the transfer layer. The surface is decorated. According to the shape of the product or the molding conditions, in the manufacturing method, since the transfer sheet of the opening portion is stretched to the flow direction of the molten resin by the flow and heat of the molten resin, the movement of the transfer sheet of the metal portion is suppressed, In some cases, the molded resin portion located at the end before the flow of the molten resin may wrinkle the transfer sheet near the boundary of the metal portion.

The invention aims to obtain a method for producing a transfer jewel which is simple and surely applied with a transfer layer on the surface of a decorative body, a transfer garnishing device, and a transfer jewel. Moreover, the present invention provides a method for manufacturing a transfer and ornament which is capable of preventing wrinkles of a transfer sheet at the time of decoration, and which is simple and surely decorated by a transfer layer, a transfer and decoration device, and a transfer Inca jewelry for the purpose.

The first characteristic method of the method for producing a transfer jewel according to the present invention includes the step of arranging the object to be decorated in the first mold, and arranging the transfer sheet having the transfer layer on the surface of the object to be decorated a step of clamping the first mold and the second mold to form a cavity between the second mold and the transfer sheet; and injecting a medium into the cavity by the medium The transfer sheet is pressed against the object to be decorated, and the transfer sheet is heated by the medium to transfer the transfer layer to the object to be decorated.

In this manner, since the transfer sheet is placed at a position opposed to the surface of the object to be decorated, the medium is injected into the cavity formed between the second mold and the transfer sheet, and the medium is transferred. Since the printing sheet is pressed against the decorative body, even if the surface of the decorative body has a three-dimensional shape such as a deep shape, it is difficult to accumulate air between the transfer sheet and the decorative body to enhance the transfer sheet and the quilt. The adhesion of the decorative body is such that the transfer layer is surely transferred to the object to be decorated.

Further, as a medium for pressing the transfer sheet toward the decorative body, pressure and heat are applied to the transfer sheet by using, for example, a molten resin. As a result, the transfer sheet can be softened by the heat of the medium while being pressed against the object to be decorated, and the transfer layer can be easily transferred to the object to be decorated. Furthermore, it is not necessary to use a bulky manufacturing apparatus to manufacture a transfer jewel by simply ejecting a metal mold.

The second characteristic means of the method for producing a transfer jewel according to the present invention is that the medium is a thermoplastic resin.

The medium injected into the cavity formed between the second mold and the transfer sheet is used only for pressing the transfer sheet against the surface of the object to be decorated, and is not included in the final manufactured transfer jewelry. . Therefore, the possibility that the medium after use is directly discarded becomes high, and in the case where the medium is, for example, a molten resin, the environment may be adversely affected. However, when the medium is a thermoplastic resin, when the transfer sheet is pressed against the surface of the object to be decorated, it is emitted at a high temperature, and then solidified even after being cooled at a low temperature, and softened as long as it is heated again. Therefore, the thermoplastic resin used for pressing the transfer sheet against the surface of the decorative body can be reused without being discarded.

The third characteristic means of the method for producing a transfer jewel according to the present invention includes the step of suction-retracting a step of bringing the transfer sheet into contact with the object to be attached before the mold clamping.

According to the present feature, before the transfer of the transfer sheet to the medium on the surface of the object to be decorated, since the transfer sheet is in a state of abutting against the object to be decorated, the transfer sheet is pressed against the decorated article in the medium. When the surface of the body is formed, it is difficult to cause the transfer sheet to abut against the surface of the object to be decorated. Therefore, the adhesion between the transfer sheet and the object to be decorated can be improved, and the transfer layer can be surely transferred to the object to be decorated.

A fourth characteristic method of the method for producing a transfer jewel according to the present invention is to provide a step of holding the transfer sheet along a direction of a mold clamping of the first mold and the second mold.

According to the present feature, since the transfer sheet is held along the mold clamping direction of the first mold and the second mold, the transfer sheet can be prevented from being displaced from the surface of the decorative body, and the transfer sheet can be surely held The surface of the decorative body abuts away.

A first characteristic configuration of the transfer jeweling device according to the present invention includes: a first mold and a second mold which are internally formed with cavities and are mold-lockable to each other; and the mounting portion is configured to have a transfer layer a state in which the transfer sheet is in contact with the inner surface of the first mold so that the object to be attached can be placed; and a medium injection mechanism for pressing the transfer sheet to the medium of the object to be decorated Inject into the cavity.

According to this configuration, the object to be attached can be placed on the placing portion in a state in which the object to be attached is brought into contact with the transfer sheet, and the medium is injected from the medium injection mechanism into the cavity formed between the second mold and the transfer sheet. The transfer sheet is pressed to the object to be decorated by the medium, and as a result, a transfer additive which is surely transferred with the transfer layer can be manufactured.

According to a second aspect of the present invention, there is provided a transfer holder device comprising: a grip holder that holds the transfer sheet along a mold clamping direction of the first mold and the second mold to cause the transfer The print is placed close to the ornamented body.

According to this configuration, the object to be attached is brought into contact with the transfer sheet in a state in which the transfer sheet is held by the grip holder, so that the transfer sheet can be surely held in contact with the surface of the object to be decorated, and the transfer sheet can be reliably held. The state of leaving the surface of the ornamented body. As a result, in a state in which the transfer sheet abuts against the surface of the object to be decorated, the positional deviation of the transfer sheet from the object to be decorated can be suppressed, and the transfer sheet is separated from the surface of the object to be decorated. The placement of the decorated body on the placement portion of the first mold and the removal of the transfer ornament from the first mold are facilitated.

According to a third aspect of the present invention, in the transfer tool device of the present invention, the peripheral portion of the object to be decorated is separated from the inner surface of the first mold while the object to be attached is placed on the mounting portion. The way to set the height of the placement portion.

In the state in which the object to be attached is placed on the placing portion, the height of the placing portion is set such that the peripheral edge portion of the decorative body is separated from the inner surface of the first mold. The printed sheet is wound around the inner side of the peripheral portion of the decorative body to expand the transfer area of the surface of the decorative body.

A fourth characteristic feature of the transfer jeweling device according to the present invention is that the inner surface of the first mold is provided with a point for preventing adhesion of the transfer layer from the transfer sheet.

According to this configuration, when the inner surface of the first mold is provided with an anti-adhesion coating for preventing transfer of the transfer layer from the transfer sheet, the transfer layer can be reliably prevented from being transferred to the inner surface of the mold.

A fifth characteristic feature of the transfer jeweling device according to the present invention is that a pressurizing mechanism for increasing the pressure of the medium in a state where the medium is injected into the cavity is provided.

According to this configuration, when a pressurizing mechanism for injecting the medium into the cavity and increasing the pressure of the medium is provided, the medium injected into the cavity is compressed, and the transfer sheet pair is further integrally increased. The pressing force of the surface of the decorative body can more reliably perform the transfer of the transfer layer to the surface of the decorative body.

The transfer jewel of the present invention is characterized in that the transfer layer is transferred to the concave portion or the convex portion formed on the surface of the object to be decorated by using the first to fourth feature means.

When the transfer layer is transferred to the concave portion or the convex portion formed on the surface of the decorative body by the first to fourth features, the concave portion or the convex portion formed on the surface of the decorative body is fine. The transfer layer that is subjected to the heat and pressure of the media is in close contact with the concave portion or the convex portion. As a result, in the transfer jewel, the concave portion or the convex portion formed on the surface of the decorative body is surely transferred by the transfer layer to be decorated. Moreover, on the transfer jewel, the surface finish (texture, knurling, etc.) of the garnish can be matched with the position of the pattern.

Specifically, as shown in Fig. 1, the first gripper 4 is provided at a position closer to the die face 1a than the second gripper 5, and the movable plate 7 provided in the space portion 1B inside the first die 1 is provided. An operation rod 6 that penetrates the inside of the first mold 1 is attached. Further, the second gripper 5 is attached to the movable plate 9 provided in the space portion 1B inside the first die 1 with the operating lever 8 penetrating the inside of the first die 1.

The movable plate 9 is provided at a position away from the mold surface 1a from the movable plate 7 to which the operating rod 6 of the first clamp 4 is attached, and the operating rod 8 passes through the movable plate 7 and is attached to the movable plate 9. In the space portion 1B, the movable plate 7 is pushed in a direction away from the die face 1a by the elastic member 7a disposed between the movable plate 7 and the wall surface on the die face 1a side of the space portion 1B. The movable plate 9 is coupled to the movable plate 7 through the elastic member 9a, and the elastic member 9a pushes the movable plate 9 in a direction away from the die face 1a. As a result, the first grippers 4, 5 are pushed toward the die face 1a. Further, the space portion 1B is provided with a fixing plate 10 at a position closer to the die surface 1a than the movable plates 7 and 9.

When the movable plate 9 is subjected to a pressing force generated by an eject rod, an air cylinder, or the like, and is moved toward the die face 1a of the first die 1 against the elastic member 9a, the movable plate 9a is movable through the elastic member 9a. 7 also moves in the same direction, and the operating levers 6, 8 separate the first gripper 4 and the second gripper 5 from the die face 1a. At this time, the transfer sheet 12 is in a state of being held by the first gripper 4 and the second gripper 5. When the movable plate 9 further moves in the direction toward the die face 1a, the movable plate 7 abuts against the fixed plate 10 and stops. However, the movable plate 9 also moves against the elastic member 9a and moves toward the die face 1a after the movable plate 7 is stopped. As a result, the second gripper 5 is separated from the first gripper 4 and becomes a position that allows the movement of the transfer sheet 12.

On the other hand, when the movable plate 9 is not subjected to the pressing force of the eject lever, the air cylinder or the like, the movable plate 9 is elastically biased by the elastic member 9a, and moves away from the die face 1a of the first die 1, The movable plate 7 is also biased by the elastic force of the elastic member 7a to move away from the die face 1a of the first die 1. In other words, the first gripper 4 and the second gripper 5 are close to the die face 1a, and the second gripper 5 abuts against the first gripper 4, and is held and held at the position of the transfer sheet 12.

[Media Injection Agency]

In the second mold 2, a gate 11 for injecting and injecting a molten resin (media) 30 is provided as a medium injection mechanism. The gate 11 is formed on the cavity surface 2A so as to face the surface of the object 20 to be placed on the mounting portion 1A. Further, in a state where the first die 1 and the second die 2 are mold-locked, the medium is injected from the gate 11 to the cavity formed between the cavity face 2A and the transfer sheet 12 disposed on the surface of the object 20 to be decorated. V.

[media]

The medium 30 to be injected is a liquid having a viscosity or a molten resin having fluidity. As the molten resin, either a thermoplastic resin or a thermosetting resin may be used. However, the medium 30 injected into the cavity V formed between the cavity face 2A and the transfer sheet 12 is used only for pressing the transfer sheet 12 to the surface of the object 20 to be decorated. Therefore, in the present invention, the used medium 30 is not directly discarded and reused. Therefore, for example, a thermoplastic resin is used as the molten resin. When the medium 30 is a thermoplastic resin, it is injected at a high temperature when the transfer sheet 12 is pressed against the surface of the object to be decorated 20, and then solidified even after becoming a low temperature, but softened by reheating, and thus Easy to use. Examples of the thermoplastic resin include PC/ABS, PE, ABS, PS, SAN, EVA, PVC, PMMA, PA, POM, and PBT.

[Resin forming process]

At this time, the transfer sheet 12 is held by suction by the suction portion 13 provided in the first mold 1.

As shown in Fig. 3, when the mold clamping of the first die 1 and the second die 2 is completed, the die face 2A of the second die 2 and the transfer sheet 12 disposed on the surface of the object 20 to be decorated are Forming a cavity V.

Next, as shown in Fig. 4, the molten resin 30 is injected into the formed cavity V from the gate 11 provided in the second die 2. At this time, the transfer sheet 12 is pressed toward the surface of the object to be decorated 20 by the molten resin 30 injected into the cavity V, and as a result, the transfer sheet 12 is surely attached to the surface of the object 20 to be decorated. . Here, in the case where the molten resin 30 injected into the cavity V is at a high temperature, the molten resin 30 heats the transfer sheet 12, and further heats the surface of the decorated body 20 to more reliably perform the transfer sheet 12 The transfer layer 12a is transferred to the surface of the object 20 to be decorated. Here, the temperature of the molten resin to be emitted is set to, for example, 280 ° C or higher, and the first mold 1 and the second mold 2 are set to, for example, 80 ° C or higher.

As shown in Fig. 5, after the molten resin 30 is cured, the second mold is separated from the first mold to release the mold release, and the transfer film 12 is continuously held by the first clamp 4 and the second clamp 5 Leave the surface of the body 20 to be decorated. Then, as shown in FIG. 6, the transfer garnish P is pushed out by the push-out bar (not shown) provided in the first die 1, and is pushed out by the push-out bar (not shown) provided in the second die 2. The molten resin 30 after hardening is pushed out, and the feeding of the transfer sheet 12 is resumed.

The obtained transfer garnish P is surely decorated with the surface of the decorative body 20 by the transfer layer 12a. In this manner, the surface of the object to be decorated 20 can be decorated by the manufacturing method of the present invention and the transfer and decoration device. When a thermoplastic resin is used as the molten resin 30, another process of heating the resin after curing to return the molten resin or the like is performed to reuse the medium to be injected into the cavity V.

As a result, the area of the cavity V becomes small, the injected molten resin 30 is compressed, and the pressing force of the transfer sheet 12 against the surface of the decorative body 20 is increased, and the transfer layer pair can be more reliably performed. The transfer of the decorative body 20 is carried out.

[Another embodiment]

(1) In the above-described embodiment, the attached body 20 is placed on the mounting portion 1A of the first die 1 in a state in which the peripheral edge portion thereof is in contact with the die face 1a of the first die. As shown in Fig. 8, the height may be set to be placed on the mounting portion 1A of the first mold 1, and the periphery of the object to be decorated 20 may be placed in a state in which the object to be decorated 20 is placed on the placing portion 1A. The portion 20b is separated from the die face 1a of the first die 1. In this manner, when the peripheral edge portion 20b of the decorative body 20 is away from the die face 1a of the first die 1, the transfer sheet 12 can be wound from the peripheral edge portion 20b of the decorative body 20 to the inside thereof, and is added. The transfer area of the decorative body 20 is expanded. Further, when the transfer sheet 12 and the molten resin 30 are wound from the peripheral edge portion 20b of the decorative body 20 to the inside thereof, the molten resin 30 and the transfer sheet 12 may not be smoothly attached from the decorated portion during mold opening.

Alternatively, the mechanism for removing the undercut is assembled to the metal mold.

(2) As shown in Fig. 8, the mold-preventing coating layer 14 for preventing transfer of the transfer layer from the transfer sheet 12 may be applied to the mold surface 1a of the first mold 1. In this manner, if the adhesion preventing coating layer 14 is applied to the die face 1a, the transfer layer 12a can be surely prevented from being transferred to the die face 1a. The adhesion preventing coating layer 14 is applied to the die surface 1a by ruthenium or fluorine processing, surface unevenness treatment (bead etch, etching), or both.

(3) The friction reducing member such as Teflon (registered trademark) or a coated ring may be disposed on the surface of the first clamp 4 and the second clamp 5 that holds the transfer sheet 12. In this way, when the transfer sheet 12 is pressed against the convex portion 20a of the decorative body 20 before the mold clamping, the movement of the transfer sheet 12 is allowed without excessively stretching the transfer sheet 12. It is made to follow the convex portion 20a of the to-be-decorated body 20.

(4) In the above-described embodiment, the unevenness is not formed on the surface of the object to be decorated 20, but as shown in Fig. 8, the ornamented body 20 may have, for example, a penetrating portion 20c and the like, and may have irregularities formed on the surface. In this case, the molten resin (media) 30 presses the transfer sheet 12 so as to be in close contact with the penetration portion 20c, so that the transfer layer 12a is reliably transferred to the object 20 to be decorated.

(5) In the above embodiment, only the transfer layer 12a is decorated on the surface of the decorative body 20. However, the first mold 1 may be provided with a gate for emitting resin, and the decorative body 20 may be provided. While the surface is decorated with the transfer layer 12a, the resin portion is formed on the back surface of the object 20 to be decorated. Further, a temperature adjustment mechanism for adjusting the temperature of the metal mold may be provided in the first mold 1 to adjust the temperature of the object 20 to be decorated. As described above, when the decorative body 20 is, for example, a metal body, the transfer layer of the transfer sheet is more easily transferred to the surface of the object 20 to be heated by the temperature adjustment mechanism.

(6) In the above embodiment, the transfer garnishing device is disposed in the vertical direction (longitudinal direction), but may be disposed in the horizontal direction (lateral direction).

(7) In the above embodiment, the transfer sheet 12 having the transfer layer 12a is used as an example. Alternatively, the surface of the object 20 to be decorated may be provided, and the base sheet of the smooth surface or the base sheet may be provided. An insert sheet to which a pattern or the like is attached is directly integrated and decorated. Further, in the above-described embodiment, the long film material in which the transfer sheet 12 is formed into a roll shape is arranged and disposed at a position facing the surface of the object to be decorated 20, but the decorative body may be blended. The outer shape of the 20 is configured to be cut by the cutter, or any shape larger than the ornamented body 20 (for example, a rectangular branch blade).

In the method of manufacturing a transfer jewel according to each embodiment of the present invention, when the transfer sheet 12 is adhered to the surface of the object to be decorated 20, and the transfer layer 12a is transferred, the pressure of the molten resin 30 is used. heating. The pressurizing system directly presses the transfer sheet 12, and the heating is direct heating of the transfer sheet 12 and heating of the object to be decorated 20. Since the transfer sheet 12 is adhered to the surface of the object to be decorated 20 by a fluid such as the molten resin 30, it is of course not necessary, even in the case of embossing, in the case where the surface of the object to be decorated 20 is smooth. In the case of a fine uneven shape such as a wrinkle, the molten resin 30 also flows into the uneven shape, and the transfer sheet 12 is adhered to the uneven shape with good precision, and the transfer layer 12a can be transferred to the uneven shape with good precision. Alternatively, even in the case of a large uneven shape, the transfer layer 12a can be transferred to the corner of the uneven shape with good precision. Further, since it is gradually expanded from the inflow point of the molten resin 30 and pressurized by the flow of the molten resin 30, it is also possible to effectively prevent the transfer sheet 12 from being adhered to during the process of bonding the transfer sheet 12 to each other. The occurrence of a so-called bubble in which air is accumulated between the decorated bodies 20 is formed.

Further, in the method for producing a transfer jewel according to each of the embodiments of the present invention, since the base sheet 12b can be selected to have a good dimensional stability and is not easily deformed by printing and drying, the printing accuracy of the position or size of the pattern can be used. The high transfer sheet 12 is used for transfer. Therefore, as a result, the transfer jewel P having a high positional accuracy of the position or size of the pattern and the uneven shape of the decorative body 20 can be manufactured.

In the present invention, the decorated body 20 may be a composite having a surface in which the metal portion 50 and the molded resin portion 81 are continuous as shown in Fig. 9. Referring to (1) and (2) of the ninth aspect, the composite product has a rectangular-shaped metal portion 80 that is opened in the center from the center, and a molding resin that is integrated into the entire back surface of the metal portion 80 so as to fill the opening 83. The unit 81 is composed of. The composite system has a shape in which the periphery slightly extends downward. The metal portion 80 constitutes a part of the surface of the composite, and the surface of the molded resin portion 81 constitutes another portion of the composite. The surface of the metal portion 80 is smoothly connected to the surface of the molded resin portion 81. As an example of the transfer garnish, the opening 83 may be a front side frame of a mobile phone or a smart phone of the liquid crystal display unit.

Although not shown, in the transfer jewel, the molding resin portion 81 can be used to form a boss or a rib for fitting the back side frame to the back surface of the transfer jewel. At this time, since it is no longer necessary to attach the ribs or the like in another step, and the ribs or the like are integrally formed, the thickness of the entire frame body can be made thin. Referring to (3) of Fig. 9, the transfer jewel is provided with a transfer layer 12a formed to cover the surface of the metal portion 80 and the surface of the molded resin portion 81. The transfer layer 12a is, for example, a transparent hard coat layer composed of a photocurable resin or a thermosetting resin and having a surface strength improved. The transfer layer 12a may be a single layer or a plurality of layers, or may be partially patterned in accordance with the shape of the composite.

The metal portion 80 is, for example, a metal platen having aluminum or the like having the convex portion 20a. The metal portion 80 may be a resin molded body, glass, or the like as long as it can be surface-applied as in the case of a metal plate. On the surface of the metal portion 80, the surface is not subjected to any pretreatment, or the surface of the alumite treatment (in the case where the metal portion 80 is aluminum), the flame treatment, the plasma treatment, etc. The surface treatment of the application of the adhesive or the like is performed in advance so that the transfer layer 12a is easily formed, and the transfer layer 12a is easily attached to the sheet which is easily attached. The surface treatment of the metal portion 80 or the coating material on the surface is required to select a suitable material in accordance with each combination of the metal portion 80 and the transfer layer 12a formed on the surface. The molding resin portion 81 can also be coated with a surface treatment or a surface of a bonding sheet or an adhesive layer so that the transfer layer 12a can be easily attached.

The constituent material of the molded resin portion 81 is, for example, a general-purpose resin such as a polystyrene resin, a polyolefin resin, an ABS resin, an ABS resin, an AS resin, or an AN resin. Further, a general engineering resin such as a polycarbonate resin or an acrylic resin, or a super engineering such as a polyimide resin or a liquid crystal polyester resin can be used. Super engineering resin. Further, a composite resin to which a reinforcing material such as glass fiber or inorganic filler is added may be used.

In the case where the decorative body 20 is a composite product, the decorative body 20 shown in FIGS. 1 to 8 is regarded as a simplified description of the composite product shown in FIG.

In the case where the decorative body 20 is a composite product, the invention is a method of manufacturing a transfer jewel which integrates the metal portion 80 constituting one of the surfaces with the molded resin portion 81 constituting the other portion of the surface. The surface of the composite after the finishing is provided with a step of arranging the composite in the first mold 1; and the transfer sheet 12 having the transfer layer is placed across the surface of the metal portion 80 and the surface of the molded resin portion 81. a step of positioning 82 at a position opposite thereto; a step of clamping the first die 1 and the second die 2 to form a cavity between the second die 2 and the transfer sheet 12; and placing the medium 30 The step of ejecting to the cavity, pressing the transfer sheet 12 against the composite with the pressure of the medium 30, and heating the transfer sheet 12 with the medium 30 to secure the transfer layer to the surface of the composite. Further, prior to the step of arranging the composite 20 described above, there is a step of preparing the composite 20. For example, it is manufactured by removing the decorative sheet S from the manufacturing method shown in Fig. 7 of Japanese Patent Application No. 2009-272836. Specifically, the step of disposing the metal portion 80 in the mold, the step of clamping the mold and ejecting the molten resin to the cavity, and the step of ensuring integration of the metal portion 80 and the molding resin portion 81 by holding the pressure and cooling And the step of opening the mold to take out the composite 20. The metal portion 80 may be formed into a predetermined three-dimensional shape before being placed in the mold, or may be configured to be deformed into a predetermined three-dimensional shape at the time of injection molding.

Further, the invention is a transfer garnish for manufacturing a transfer garnish which is a surface of a composite in which a metal portion 80 constituting one of the surfaces is integrated with a molded resin portion 81 constituting other portions of the surface. In the case of the decoration, the first mold 1 is formed with a mounting portion that is placed on the surface of the composite product so that the transfer sheet 12 having the transfer layer is disposed on the surface; 2, forming a cavity between the surface of the transfer sheet 12 by the mold clamping with the first mold 1, and a medium injection mechanism for injecting the medium 30 for pushing the transfer sheet 12 to the composite into the mold hole.

Further, the present invention is a transfer decorative article comprising: a composite product in which a metal portion 80 constituting one of the surfaces is integrated with a molding resin portion 81 constituting another portion of the surface, and a concave portion or a convex portion is formed on the surface thereof. And the transfer layer is transferred to the concave portion or the convex portion using the above-described manufacturing method.

In this manner, since the transfer sheet 12 is disposed at a position opposed to the surface of the composite, the medium 30 is injected into the cavity formed between the second mold 2 and the transfer sheet 12, by Since the medium 30 presses the transfer sheet 12 to the composite product, even if the surface of the composite product has a three-dimensional shape such as a deep drawn shape, air accumulation between the transfer sheet 12 and the composite product is less likely to occur, and the transfer sheet is lifted. 12 is intimate with the composite, and the transfer layer is surely transferred in the composite. The boundary 82 between the metal portion 80 and the molded resin portion 81 can also be reliably transferred. In the invention, since the transfer sheet is adhered to the surface of the composite by the pressure and heat of the medium 30, the wrinkles of the transfer sheet 12 during the decoration can be prevented, and the surface of the composite can be easily and surely transferred by transfer. The layer is decorated. Even if the concave portion or the convex portion formed on the surface of the composite is fine, the transfer layer that receives heat and pressure from the medium adheres to the concave portion or the convex portion. As a result, in the transfer jewel, the concave portion or the convex portion formed on the surface of the composite product is surely transferred by the transfer layer to be decorated.
