Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a frame-attached glass having a shiny part such as a metal molding, and a novel manufacturing method for manufacturing the same by an integral molding method.

[Prior Art] Gaskets or moldings made of synthetic resin or rubber are usually provided on the peripheral edges of glass, window panes, etc. used in structures such as automobiles and buildings for the purpose of decoration or sealing. ing.

This frame is integrally formed with the window material by injection molding or rim molding on the periphery of the window material, which is called a module assembly window.
e Assembly Wi, abbreviated as ndowMAW). This MAW is a conventional one-piece method in which the window glass is placed in a mold, the frame material is injected into the mold, a gasket is formed around the window glass in the mold, and the gasket is removed from the mold. Manufactured by a molding method (for example, JP-A-57-158481, JP-A-58-736)

In the method of manufacturing a window glass with a frame by gluing or fitting a frame separately formed by extrusion molding etc. to the peripheral edge of the window material, the frame formed in a straight line is attached to the peripheral edge of the window glass. Since the window glass is attached while being bent to fit the window, there are problems such as wrinkles at the corners and difficulty in attaching the window glass when it has a complicated shape. Compared to this,
In addition to solving the above-mentioned difficulties, MAW products have good bonding properties between the frame and the window material, and there are fewer seams between the frame (also, the frame is relatively thin and has little difference in level from the surface of the window material). It has the advantage of being possible.

One of the reasons why MAW is used as windows for automobiles is that it provides fluid engineering and appearance effects due to the above advantages.For example, it is used for opera windows, side windows, roof windows, rear windows, etc. It is also used as a fixed window such as a front window. Furthermore, the application of MAW to movable windows such as door windows is also being considered.

[Problems to be Solved by the Invention] By the way, in automobile window glasses, etc., a shiny part made of metal such as SUS is attached to the frame part to match the appearance with the structure and improve the aesthetic appearance. This may be required. There is an adhesive method for attaching the bright part to the window glass of the frame material later, but there is a possibility that it will come off due to vibration or impact. For more secure mounting using tools, it is necessary to install the tools in advance on the frame etc. so that the tools do not come out on the surface due to appearance issues, and the number of steps increases, so it is difficult to do so. A MAW that is integrally molded including the bright part is desired.

In this case, the bright part is installed in the mold in advance, and then the glass is placed in this mold and the mold is tightened to fill the space for the frame formed between the mold and the glass periphery. A possible method is to pour a frame material such as synthetic resin and integrally mold the glass, frame, and bright part. However, in order to attach the bright part to the mold, the worker must put his body inside the mold, and in order to attach the bright part to the mold with good dimensional accuracy in such a working position, There are considerable difficulties and there are also safety issues.

The present invention has been made in view of the current situation, and is intended to provide a structure of a MAW having a bright part that is safe and has good dimensional accuracy (that can be manufactured by an integral molding method), and a method for manufacturing the same. Further, the present invention provides a MAW structure having a bright part with improved appearance, and also enables automation of the manufacturing process.
Its purpose is also to provide a method for manufacturing.

[Means for Solving the Problems] The inventors of the present invention conducted research in accordance with the above intention, and found that a method of attaching the bright part to the glass and arranging it inside the mold, rather than the mold, is easier for the operator. I came up with the idea that this is easy and that dimensional accuracy can be ensured, and I was able to arrive at a structure of a MAW having a bright part and a manufacturing method thereof that can realize this.

That is, the present invention provides a fixture for the bright part that engages with the edge of the peripheral edge of the glass, and a fixture for the bright part that is arranged on the upper surface of the frame of the peripheral part of the glass so that its surface is exposed, and that the fixture for the bright part engages with the edge of the glass peripheral edge. This is a glass with a frame body having a bright part, characterized in that it consists of a bright part fixed to the glass, and a frame integrally formed with the bright part and the bright part fixture at the peripheral edge of the glass.

Further, as a method for realizing the present invention having the above structure, a window glass provided with a frame is placed in a mold, and a frame material is injected into the peripheral edge of the window glass and solidified. In the manufacturing method for window glass, first, a fixture for the bright part is attached to the edge of the periphery of the window glass, then the bright part is fixed to the fixture for the bright part, and the fixture for the bright part and the bright part are installed. By placing the window glass in a mold, providing a space for forming a frame at the periphery of the window glass, and injecting frame material into the space, the frame, the fixture for the bright part, and the bright part are formed. The present invention provides a method for manufacturing a glass with a frame having a glittering part, which is characterized in that the glass is integrally molded with the glass.

FIG. 1(a) is a partial sectional view showing the structure of a specific example of the present invention, in which 1 is glass, 2 is a synthetic resin molding, 3 is an SUS molding, and 4 is a clip. The clip 4 is attached to the glass, and the SUS molding is integrally molded with the molding 2 of the frame while being fixed with this clip. In the present invention, the frame 2 is integrally molded by placing the clip 4 on the glass 1 and placing the SUS molding 3 on the clip 4 in a mold. Details of the manufacturing method will be specifically explained in the Examples section below.

In the example of FIG. 1(a), a clip 4 is used as a fixture for the bright part.
In addition to the method of fixing with several clips, a method of fixing to the glass 1 with a continuous fastener may also be used. The bright part may be made of metal such as SUS molding, or -yfz/e shown in Fig. 1(b).
As in another specific example, it may be one in which the SUS molding 3 and the PVC lip part 5 are integrally molded by extrusion molding, or if it includes a part made of other shiny materials, The material is not particularly limited.

[Function] In the present invention, since a bright part such as a 5LIS molding is set on the glass, the molding tact, that is, the time between moldings and the time between moldings, can be made shorter than when the bright part is set on the mold side. I can do it.

And since the worker does not have to put his or her body inside the mold,
In addition to being highly safe, there is a high possibility of process automation. Furthermore, the work of setting the glass bright part is easy and the installation is highly accurate, so the resulting product is also highly accurate. This ease of mold matching is effective in preventing scratches on the bright parts of SUS moldings and the like and in preventing glass breakage. Furthermore, in the present invention, the bright parts of the SUS molding etc. are manufactured in a separate process, and can be manufactured with high precision. SOS mall etc. P
According to the method of manufacturing a structure having a lip part such as VC by extrusion molding etc. in advance and attaching it to the glass as a bright part with a fixing tool, a lip of SUS molding is attached to the upper and lower parting parts of the mold. Since it can be placed through the frame, it is possible to prevent the appearance of undesirable flakes from forming on the outer surface of the product, and the frame itself is not visible.
The selection of the frame material depends only on its functionality (the appearance does not matter too much. Also, the material of the lip part can be different from the material of the frame part, so Similarly, suitable materials can be used for the lip portion.

[Example] Example 1 A product of the present invention having the structure shown in FIG. 1 was manufactured by the manufacturing method of the present invention. First, a window glass 1 is prepared, a clip 4 is attached to the edge of the window glass 1 as shown in FIG.
) in the mold 6. As shown in FIG. 2(b), the clip 4 and S are connected by the core 7 and the cavity 8.
A window glass 1 with a US molding 3 is sandwiched, a cavity space 9 is formed at the periphery of the window glass 1, and a softened vinyl chloride resin is injected into the cavity space 9 from a gate 10 as a frame material. By solidifying this frame material in the cavity space 9, the frame 2, the SUS molding 3, the clip 4, and the glass 1 were integrally formed with good adhesion. After the solidification was completed, the mold 6 was removed as shown in FIG. 2(c), and a frame-attached glass having the 5LIS molding 3 of the present invention could be obtained. The dimensional accuracy of the product was very high, and there were no scratches on the surface of the SUS molding.

In the above manufacturing method of the present invention, it is preferable to use not only normal injection molding but also reaction injection molding (rim molding).

The frame material of the present invention is made of synthetic resin, rubber, etc., and is particularly preferably made of elastomer or soft synthetic resin. A synthetic resin melt or a fluid synthetic resin raw material mixture that reacts in a mold to become a synthetic resin is used. Examples of the former include, but are not limited to, molten soft vinyl chloride resin, thermoplastic polyester elastomer, styrene-diene thermoplastic elastomer, and ethylene-unsaturated carboxylic acid copolymer.

Examples of synthetic resins obtained from the latter raw material mixture include, but are not limited to, polyurethane elastomers, polyurethaneurea elastomers, polyurea elastomers, polyamide resins, epoxy resins, and unsaturated polyester resins. It's not something you can do.

In the present invention, the material of the bright portion prepared in advance is not particularly limited as long as it has brightness, but metal materials such as SUS molding are preferred, for example. In addition, when a lip portion 5 etc. is provided on the bright SUS molding 3 as shown in FIG. 1(b),
This lip portion can be made of the same material as the frame material described above, but may be the same as the frame material or may be different from the material provided that the lip portion has sufficient adhesion to the frame material and glass.

Various plate glasses can be used as the glass of the present invention. For example, even if it is a single piece of normal glass, it may be laminated glass with an interlayer film, laminated glass that is made by bonding two pieces of glass with an interlayer film such as polyvinyl butyral, or polyurethane resin or polyester on one side of one glass or laminated glass. It may also be a valley-type glass sheet made of laminated sheets of resin or the like - double-glazed glass in which two sheets of glass are laminated with a gap between them, the periphery is sealed, and the gap is filled with dry air, nitrogen gas, etc. Further, these glasses may be strengthened by heat treatment or chemical treatment, or may be strengthened by air cooling. Furthermore, it may be a simple flat glass or a processed plate glass. Examples of processed plate glass include front, side, rear, and door glass for automobiles.
It may be a window glass for a sunroof, a plate glass for construction, a plate glass used for other purposes, or the like. Moreover, the present invention may be a plate glass having surface irregularities such as a patterned glass.

Further, the window glass to which the present invention is applied may have a glass surface subjected to various treatments. For example, it may be plated with heat ray reflective glass or coated with ceramic. Alternatively, the frame may be made of glass that has been subjected to a suitable treatment to form the frame. For example, glass with a brimer coated on the peripheral edge of the glass where the frame is formed to improve the adhesive strength with the frame, and conversely, a protective coating that can be peeled off after the frame is formed on the non-frame forming surface. Glass that has been coated or has a removable film adhered to it, or glass that has had a sealing elastic material applied or a sealing elastic material adhered to the part of the non-frame forming surface that is in contact with the frame forming surface. etc.

[Effects of the Invention] As explained above, according to the present invention, a frame-attached glass having a bright part can be manufactured by an integral molding method in a safe and easy manner, and with improved work precision and product precision. The excellent effect of being compatible with process automation can be obtained.

Furthermore, the glass with a frame having a bright part according to the present invention has high dimensional accuracy, has no scratches on the bright part, has no cracks on the frame part, and has an improved appearance, and has a lip part. Now, it is possible to use a frame made of a different material, improving performance and appearance, and expanding material selection, which can also be expected to improve product value.
