Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to window materials made of transparent plate-like bodies, particularly glass plates, synthetic resin plates, etc., such as flat plate-shaped, bent plate-shaped raw or reinforced Single-panel, laminated, laminated, multi-layer, architectural window materials with film or other processing applied to the surface of the panels, vehicle window materials, etc., especially synthetic resin moldings or gaskets directly on the outer surface of the peripheral edges of automotive window materials. The present invention relates to a window material with an assembly formed by integrally molding (hereinafter both referred to as moldings) and a method for manufacturing the same. [Prior Art] Conventionally, as a means for attaching a transparent plate-like body such as a glass plate to a vehicle window opening, in the case of an automobile, a transparent plate-like body such as a glass plate is attached to the joint between the inner panel and the outer panel of the vehicle body, and to the peripheral edge of the glass plate. The glass plate is attached to the car body through a separately molded weather strip that is designed to fit into the weather strip, and the legs are inserted between the glass plate and the periphery of the glass plate mounting flange on the car body panel. The so-called direct glazing method, which uses a separately molded peripheral molding that is fixed with adhesive, has been adopted, and a mounting method that has recently been gaining attention is to attach a molding or molding to the outer surface of the peripheral edge of the glass plate in advance using a reaction injection molding method, etc. The so-called encapsulation method, in which a gasket is directly molded and easily attached to the vehicle body with one touch using adhesive or the like, is being adopted. Among these methods, a decorative metal coating film such as aluminum or chromium is attached to the outer surface of the molding or gasket after molding, or by plating or vapor deposition, and semi-rigid polyvinyl chloride or Reinforcing with metal bands and further fixing to the vehicle body via protrusions are known as described in, for example, Japanese Patent Laid-Open No. 54-100022 and Japanese Patent Publication No. 61-7368. [Problems to be solved by the invention] Among the conventional methods mentioned above,
The methods disclosed in Publication No. 100022 and Japanese Patent Publication No. 61-7368 have a simple molding and gasket structure, and can be attached to the vehicle body using a simpler adhesive method than the physical fixing method, so they are likely to become widely used. However, it is also possible to attach an aluminum or chrome film after molding, or to apply it using a mask, plating, vapor deposition, etc., or to set a metal band, etc. inside the mold during injection molding. Since the decoration and exterior are done by applying the metal strips, etc., the pasting and plating work is complicated and inefficient. It is difficult to fix it in position, and if it moves, it tends to shift and become deformed.Furthermore, a metal band or the like is set in the mold, and molten resin is poured into the cavity space. During injection, the resin part wraps around between the metal strip, etc. and the inner surface of the mold, causing problems such as burrs tending to occur on the outer surface of the metal strip, etc. after removal from the mold. [Means for Solving the Problems] The present invention has been made in view of the above-mentioned drawbacks of the conventional art. To provide a window material with an assembly and a method for manufacturing the same, which can solve the above problems by integrally molding a molding or gasket into a transparent plate-like body in close contact by providing a spring mechanism for pressing. . That is, the present invention is an assembly window material for a vehicle, which is formed by integrally molding a molding or a gasket made of synthetic resin on the outer surface of the peripheral edge of a transparent plate-like body, and in which the window material is used as a substrate during assembly of the window material. A window material with assembly, characterized in that a decorative/reinforcing member or a stopper member supported by a spring mechanism member is integrally provided so as to face the outer surface of the molding or gasket, and a transparent plate-like member. In the method of forming a molding or gasket made of synthetic resin on the outer surface of the peripheral edge part, the peripheral edge part of the transparent plate-shaped body is placed in an injection mold, and the peripheral edge part of the transparent plate-shaped body is used as a substrate to form a spring. A decorative/reinforcing member and a stopper member are arranged and positioned so as to be pressed and fixed to the inner surface of the mold via a mechanism member, and by clamping the mold, the transparent plate-like body is held by the clamping portion of the mold member to absorb the cushioning material. The molten synthetic resin or its raw material is mixed and injected into the cavity space constituted by the inner surface of the mold, the outer surface of the peripheral edge of the plate-shaped body, and the inner surface of the decorative/reinforcing or stopper member, and cured. The present invention provides a method for manufacturing a window material with an assembly, which is characterized in that the window material is integrally molded and then taken out from the mold. Here, the term "transparent" in the transparent plate-like material refers to transparent, translucent, colored, uneven surface patterns, etc.; Various types of glass such as
Namely, flat glass, tempered plate glass by heat treatment or chemical treatment, various types of laminated glass made by combining glass plates, resin plates, etc., laminated glass with various surface treatments such as heat ray reflective coating, tear prevention coating, black frame, etc., bent plate glass, These include various inorganic glasses such as double-layer glass, hard-coated synthetic resin plates such as polycarbonate, acrylic, and scratch-resistant sheets, and laminates made of these synthetic resin plates and inorganic glass plates. The molding that is integrally molded on the transparent plate-like body is applied to the peripheral edge of the transparent plate-like body, covering the entire circumference or almost the entire circumference of the transparent plate-like body, and various shapes are adopted for the molding, but at least transparent It is integrally molded on one side of the front and back of the peripheral edge of the plate and on the end surface, and it goes without saying that it is preferable to apply Pflimer to the required areas in advance to improve the adhesive strength. The surface preferably has a shape that satisfies a more aerodynamic structure and does not cause unpleasant wind noise, and is preferably provided with a tongue portion to improve sealing performance with the outer skin of the vehicle body. It is preferable that the back surface of the part has an uneven shape or a shape that has some kind of spring effect, and furthermore, a protrusion (for sealing) is provided around the entire circumference of the transparent plate-like body on the rising surface corresponding to the end face side of the transparent plate-like body. Or, it is preferable to make it airtight by incorporating a flexible hollow tube in its surface, and furthermore, it can be fixed by adhesive or by engagement when it is installed in alignment with an opening in a vehicle body, etc. In order to prevent this, the back surface of the molding has an uneven or concave shape to prevent the bead-shaped adhesive applied to this area from escaping, and a dam part is provided at the end for the purpose of sealing. It is preferable to provide at least one locking rib portion that serves to position the window material at the vehicle body opening, to secure it until the adhesive is fixed, and to assist in subsequent fixing. The molding can be molded using general synthetic resin molding methods such as injection molding, and in particular RIM (Reaction Injection) method.

Preferably, it is based on the law. In other words, while it generally requires a temperature of about 200 to 300℃ for the part of the mold surrounding the cavity space,
The temperature can be as low as 100°C to normal temperature, preferably as low as 50 to 80°C.
It is preferable to be able to adjust the temperature of not only the mold holding temperature but also the non-molded part because it allows the solidification rate etc. to be controlled.
Materials that require an extremely high pressure of 350 to 1000 Kg/cm ² are injected into the cavity space at a pressure ranging from normal pressure to about 6 Kg/cm ² , preferably around 3 Kg/cm ² , and are injected into the cavity space at an extremely low pressure. It has the advantage of, for example, being able to mix two components by collision and perform reaction injection. The mold itself is not particularly limited, and may be made of extremely common metal, resin, or ceramic, and the surface of the cavity space may be treated with a mold release agent, or a transparent plate-like material may be used. A substance that doubles as a buffering member or a sealing member that is different from the injected resin so as not to damage or break the surface of the body, and also to prevent the generation of burrs or to absorb the deformation of the mold and the deformation of the transparent plate. For example, a heat-resistant fluororesin or fluororubber, silicone resin or silicone rubber, or other soft resin or other elastic body, such as a single substance, a foam, a hollow body, or a composite body, is interposed between a transparent plate-like body and the inner surface of the mold to seal it. Needless to say, there are many things that can be done. Decorative/reinforcing members or stopper members set in the mold can be of various sizes, thicknesses, and shapes, such as metal or resin films, plates, nuts, etc., and these can be used as spring mechanisms. Since it is set in this way, it can be firmly clamped and fixed to the transparent plate-like body within the mold in conjunction with mold clamping, and distortions of the mold and the transparent plate-like body can be absorbed, and the position can be adjusted even when pouring synthetic resin. It allows for accurate positioning without causing distortion, and after the synthetic resin has solidified from a liquid state, the spring force can be eliminated by the resin, making it sturdy. Depending on the synthetic resin used, the strength of the spring force can be freely selected, and various materials and types of spring mechanisms can be selected, but springs are preferred. The synthetic resins used in the various molding methods, that is, the synthetic resins that can be used in the present invention, include, for example,
Polyurethane resin, low density and high density polyethylene, polystyrene, polypropylene, silicone resin, polyamide resin, nylon-6,
Thermoplastic resins such as EVA, PET, and PBT, thermoplastic rubbers such as polyurethane, ethylene-vinyl acetate, polyolefin, and styrene-butadiene, as well as vinyl ester resins, epoxy resins, silicone resins, and unsaturated polyesters. These include thermosetting resins such as thermosetting resins, blended resins, foamed polyurethane, elastomers, elastic rubbers, etc., which can be widely used, as well as ultraviolet absorbers, colorants, catalysts that control the reaction rate, It goes without saying that fillers such as foaming agents and stabilizers, as well as reinforcing agents such as glass fibers and glass flakes, may be added. Of course, it is necessary to consider weather resistance, heat resistance, strength, coefficient of thermal expansion, shrinkage ratio, surface texture, etc. [Function] As mentioned above, the window material with assembly and the manufacturing method thereof of the present invention allow various decorative/reinforcing members and fastening members to be combined with the spring force and holding force of the spring mechanism and the physical properties of the synthetic resin of the molding itself. Since it can be obtained by integrally molding various selected combinations, it has come to provide even more advanced effects. In other words, due to the spring force of the spring mechanism,
Decorative/reinforcing members, stopper members, etc. can be reliably positioned within the formwork, the transparent plate-like body can be held without excessively applying loads, and deformation of the mold and the transparent plate-like body can be absorbed. This is a measure that does not cause misalignment when injecting liquid synthetic resin, and prevents burrs from forming on decorative/reinforcing members and stopper members.In addition, the holding force of the spring mechanism prevents the occurrence of burrs on decorative/reinforcing members and retaining members. The size of the member and the stopper member,
Since it can be molded in one piece with a variety of thicknesses and shapes to choose from, there is no variation in finishing accuracy and positioning accuracy between each component, and there is no need to attach or paste these components after they are installed in the openings on the outer skin of the vehicle, resulting in a beautiful appearance. It is now possible to make full use of the physical properties of the synthetic resin that is integrally molded, allowing the freedom to choose from a wide range of highly functional moldings.For example, by increasing the elasticity of the molding, it can be used for window frame materials and car body exterior panels. It can flexibly respond to variations in surface inclination precision and distortion with the frame parts, and can greatly improve sealing performance, adhesion and fixation with them, and improve watertightness and airtightness. , the holding power and durability of the transparent plate-like body will be increased, and the installation work will not generate stress and can be easily adapted to robotization and automation using machines, and the transparent plate-like body will not be damaged or destroyed during installation. This means that no damage will occur. [Example] An example of the present invention will be described below. FIG. 1 is a partial side cross-sectional view of the spring mechanism member and the locking rib portion, which are integrally molded with the molding or gasket of the window material with assembly of the present invention on the peripheral edge of the transparent plate-like body, and are provided at the same position.

In addition, a locking rib portion 6 is provided for use in positioning, for example, when attaching to a vehicle body opening, fixing until adhesive is fixed, and further as a fixing aid after fixing. Note that an appropriate groove-like recess may be provided so that the adhesive can escape to the rising surface side, and the spring mechanism member 4 and the locking rib portion 6 do not necessarily have to be located at the same position. Considering the load, it is preferable that they be at the same position, and both need to be provided at at least one location around the entire circumference of the transparent plate-like body 2. FIG. 2 is a partial side sectional view of the molding directly integrally molded at the peripheral edge of the transparent plate-like body 2 at a portion where the spring mechanism member 4 and the locking rib portion 6 are not provided. may be extended in the longitudinal direction as it is, but as shown in the figure, the dam part 1
2 to prevent the adhesive from escaping is preferable because the amount of synthetic resin is smaller and the weight can be reduced even a little. FIG. 3 shows a state in which a transparent plate-like member or the like is set in the mold 13, immediately before injection of the liquid synthetic resin. That is, the mold 13 has a core mold 14 in the lower part and a cab mold 15 in the upper part.
Both parts 14 and 15 of these molds can be opened and closed by an operating mechanism (not shown). First, both parts are opened, and a sealant (buffer material) 17 is applied on top of the core mold 14. The transparent plate is placed so that the peripheral edge of the transparent plate is in contact with the appropriate position. Installing materials, spring mechanism members, and decorative/reinforcing members at predetermined locations on the transparent plate-like body.

Although not shown, each mold part is temperature-controlled and maintained at an appropriate temperature, so that liquid synthetic resin or raw materials can be injected at one or more locations at any time. It is becoming possible to do this as well. FIG. 4 shows a gasket or molding 1, which is held by a spring mechanism member 4 and a mounting member 8 and is integrally molded directly on the peripheral edge of the transparent plate-like body 2, and is attached to a vehicle body outer panel 19 with adhesives 20, 21. It is a partial side cross-sectional view showing a state in which the locking rib part 6 is attached.
Of course, in some cases it may be fixed by
