DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a mold. More specifically, it relates to a mold for injection having a cut structure. a 5 [Prior technology] In order to pursue the high precision and high quality of plastic parts, the traditional plastic processing technology can not meet the needs of the times, so various surface decoration processes are born: The common process is to put a decorative film into the mold. After the mold is closed, the plastic is injected to form the plastic and the film, whereby the surface of the finished product after the de-wedge is covered with the decorative film, thereby improving the beauty and practicality of the finished product; Since the film needs to be heated and formed in the mold, a large burr is reserved on the periphery of the film to absorb the shrinkage of the film after three-dimensional forming and heating, and the finished product 1 after the conventional demoulding is as shown in the first figure. The ❹I5 periphery 1a still has a large film burr 2, which must be cut by the subsequent burrs; and the finishing process can achieve the desired aesthetics and integrity of the product. However, the subsequent thin-die burrs 2 must be cut. By manual cutting or cutting with a punching device, it will cause troubles in re-machining, which is time-consuming and labor-intensive, resulting in an increase in labor, time and equipment costs. Moreover, the production efficiency 20 rate is not returned, and further, the film burr 2 around the finished product 1 is still prone to jaggedness after the above-mentioned conventional cutting process, thereby affecting the overall appearance and refinement of the finished product 1 The economic value of the finished product 1 is reduced; in addition, there is occasional occasional flashing in the process of injection molding, resulting in an unattractive finish. 4 200936355 In view of this, the inventor of this case has been carefully researched and accumulated years of experience in the development and manufacturing of related industries, and finally has the invention. SUMMARY OF THE INVENTION The main object of the present invention is to provide an injection mold having a cutting structure, which is capable of producing a high-precision finished product having a decorative film on its surface, and which can reduce labor, time and equipment costs, and improve production. effectiveness. In order to achieve the above object, the present invention provides a cutting die with a cutting structure for cutting a film located in the mold, and the (1) wealth includes a relatively openable and closed-first module and a second module, wherein one module is provided for the film, and the other module is provided with all the blade members, whereby the film and the cutting blade member are in contact with each other when the first and second modules are closed. ^ It can be seen from the above that the present invention can precisely cut the crucible by pre-cutting the inside of the mold by cutting the blade, and the post-removal and trimming operation of the conventional finished product can be omitted. Improve the precision of finished products, reduce labor, time and equipment costs, and improve production efficiency. BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the following drawings: Fig. 2 is a side view of a mold for injection having a cut structure according to a preferred embodiment of the present invention. The second figure is a combination of the first module and the cutter member of the above preferred embodiment 5 200936355. The fourth figure reveals that when the mold of the above preferred embodiment is laminated, the cutting member interferes with the film. The fifth figure is a partial enlarged view of the fourth figure. • Fig. 6 to Fig. 8 are flow charts showing the operation of the mold of the above preferred embodiment during mold clamping and injection. , yth is a schematic view of a product obtained by demolding using the mold of the above preferred embodiment. The tenth figure is similar to the eighth figure, revealing that the cutter does not completely cut the film. 10 The eleventh figure reveals another film aspect on the finished product obtained by demolding. Referring to the first and second embodiments of the present invention, a cutting die having a cutting structure, which includes a first module 10, a second module 20, and everything The cutter member 3〇, the mold 1〇〇 is combined with the mold to be used for the county process, so that the film F can be pre-cut by the F 15° 于 in the lining 100, the detailed embodiment is described in detail. The structure of the mold 1〇〇' is as follows: 凊 cooperate with reference to the second to fifth figures, the first module 1 is connected to an injection machine (not shown) having a parting surface 11 and a a mold 1 is formed on the mold surface 11 and the mold core 12 is disposed around a circularized card slot 121. In addition, an injection channel 10a is disposed in the center of the first module 10 for the plastic injection of the injection machine to the mold (10). The inner portion; the first block, the block 20 is openable and closable relative to the first module 1b, and has a cavity 22 shaped to fit the mold core 12, and a sipe 22a formed on the periphery of the cavity (refer to 6)) When the first and second modules 10, 20 200936355 20 are closed / the mold 1 and the Lai 22 are formed into a cavity 101 And the film F can be placed into the cavity 22 in any known manner, and fixed in the position of the lining cavity 1 () 1; in the actual hood, the film f is ridden by the second The clip 1D member 23 on the module 2G and reciprocable relative to the second module 2 is cooled (refer to the second figure). Since the clip is the focus of the present invention, it will not be described; ❹ the cutting member 30 is implemented in the present embodiment. For example, the ring-shaped pivot body is fixed to the annular card slot 121 of the die 12 of the first module 10, and the other 2 = is outside the chess core 12, and a blade portion 31 is formed. The length of the film (1) is greater than the thickness of the film F, and the front end thereof forms an inclination = 311, and the inclined end 311 is close to a height of one side of the cavity 1〇1 from one side of the cavity 101; When the first ϋ ^ is far closed, the cutter (4) is located in the type, and the inner wall surface 22 of the cavity 22 of the 15 block 20 is inserted into the outer portion: the sipe 22a of the cymbal Therefore, the film F is completely cut off and the side wall surface of the cavity-: cavity 101 is in contact with the second module 20'; the wall surface 221 is aligned; the inner part of the heart mold 八22 is described above the first The block member of the block 1 can be omitted. In other words, the blade member 3G is formed in the die of the first module 10 by the two-dimensional element. That is, we can see if the thin F-cutting piece is 3G in length (4) or 4 (3) in the length of the piece (3), and the adjustment is made to change the blade 31 3 adjustment mechanism (film of different thickness) And the use of the above-mentioned ring frame of 20 200936355. ~ Above ^ The components of the mold 100 of the present embodiment and their related positions are described in the in-mold film bonding forming process and its The effect and advantages of the following are: -5 f first refers to the second figure. When the first and second modules 10 and 20 are in the open state, the film F is first placed into the mold by using an inflammatory holding device 2 Within 1 ,, the clamped position of the clamp is reciprocated, so that the periphery of the film p is clamped and forced. After the clamp 23 clamps the film F, the clamping device 2 releases the film F. And exiting to the outside of the mold 100, then the film F is heated and stretched and vacuum-attracted Tightly attached to the inner wall surface 221 of the cavity 22, referring to the action flowcharts of the fourth and fifth figures, and the sixth to eighth figures, when the first and second modules 1 and 20 are operated and closed. The film F is cut by the cutting edge member 30, and it should be noted that, in the embodiment, since the length of the blade portion 31 of the cutting blade member 30 is larger than the thickness of the film F, the film F_is can be Completely cut, that is, the burrs can be removed. Of course, we can also use the cutting edge with the length of the blade equal to the film F, so that the same purpose can be achieved, and the sipe 22a of the cavity 22 can be omitted. After the film F is cut, the plastic S enters through the injection channel 1〇a of the first module 1 and is combined with the film F to be molded into the cavity 1〇1, and finally, the mold opening operation is performed. 2, the first and second modules 10, 20 are relatively open, and the finished product 300 as shown in the ninth figure is obtained. 'Specially stated that 'because the burrs of the film F have been removed in advance, the finished product 300 periphery 301 does not have a film burr, so it does not need to be processed twice to obtain South precision and high beauty. Structure outside 8 200936355 Of course, the length of the blade portion 31 of the aforementioned cutting member 30 may also be smaller than the thickness of the film F, as shown in the tenth figure, so that the sipe 22a of the second module 20 of the above embodiment It can be omitted, and the 'inclined end 311 of the blade portion 31 can also be higher than the height of one side of the cavity i〇l is greater than the height of one side away from the cavity 1〇1 15 15 , side. For the purpose of preventing the flashing, it is known from the above structure that after the mold is closed, the film F is not completely cut, so that after the injection molding, the finished product 400' shown in Fig. 11 can be obtained because the film F has been appropriately cut beforehand. Therefore, 'we only need to add the film F which is applied to the finished product 400 circumference 4〇1 to remove it, so that the product with high precision and high appearance can be obtained. It is also worth mentioning that the design of the blade portion 31 having the inclined end 311 of the present invention can not only achieve a better cutting effect, but also can block the plastic in the cavity 100 of the mold 100 when the plastic is injected. In order to avoid the occurrence of the use of flash material to improve the refinement and aesthetics of the finished product; further, since the blade portion 31 is close to a side wall surface of the cavity 1 and the cavity 22 of the second module 20 The wall surface 221 is affixed, so that the precision of the cutting can be further improved, thereby improving the delicateness and the appearance of the finished product. In summary, the present invention directly utilizes the cutting member 30 in the mold 100 to perform the pre-cutting operation of the film F, so that the film F around the finished product 300 is more accommodating, or by the material 31. Compared with the cutting edge of the film F, the blade member can remove the burrs directly when the die 1 is closed, so that the design of the blade member of the present invention can greatly reduce or eliminate the use of the blade member. The processing cost of the subsequent burr cutting operation of the decorative film can save a lot of manpower, time and equipment cost, and the production efficiency is high, and there is no difference in the film burrs around the finished product after trimming. In the case of a disorder, the finished product obtained by using the mold of the present invention has high refinement and aesthetics, and has high commercial interests and added value. • The above is only a preferred embodiment of the present invention, and the equivalent structural changes of the present invention and the scope of the patent application are intended to be included in the scope of the present invention. 200936355 [Simple description of the diagram] $-The diagram is a schematic diagram of the finished product of the surface coating.
