部にガスケット２が取付けられる。"Prior Art and its Problems" Rubber or synthetic resin gaskets or moldings (hereinafter collectively referred to as gaskets) are used to decorate or seal the periphery of vehicle window glasses such as automobiles or architectural window glasses. For example, as shown in FIGS. 2 and 3, a gasket 2 is attached to the peripheral edge of a window glass l, which is a common practice.

を要し作業性が悪いなどの問題点があった。Conventionally, the gasket has been attached to the window glass by a method in which a gas get formed by extrusion molding or the like is adhered to or fitted into the peripheral part of the window glass. However, in this method, the linearly formed gasket is bent to match the peripheral shape of the window glass before installation, which can cause wrinkles at the corners or make installation difficult when the window glass has a complicated shape. There were problems such as the need for manpower and poor workability.

A method of manufacturing a gasketed window glass has been proposed, which consists of forming a gasket around the glass and removing it from the mold (for example,

窓ガラス１を成形型５内から取出す。To explain this method in more detail, Figure 4 (a
), the window glass 1 is placed in a mold 5 consisting of a core 3 and a cavity 4, and as shown in FIG. 4(b), the window glass 1 is sandwiched between the core 3 and the cavity 4, A gap space 6 is formed at the periphery of the window glass 1. Then, a gasket forming material such as a melt of rubber or elastomer or a raw material mixture capable of forming rubber or elastomer is injected into this cavity space B from the gate 7. The gasket 2 is formed by solidifying this gasket forming material within the cavity space θ. Then, as shown in FIG. 4(C), the core 3 and the cavity 4 are opened, and the window glass 1 provided with the gasket 2 is taken out from the mold 5.
しかし、上記の方法においては、成形型５と窓ガラスｌ

いという問題点があった。However, in the above method, the mold 5 and the window glass l
When a gasket forming material is injected onto the contact surface with the gasket, there is a problem in that the gasket material invades the contact surface and tends to cause flaking or the like.

、個々の製品によってどうしても曲げ形状にバラツキが
生じて、成形型５を締付けたときに窓ガラスｌに集中応
力がかかり、破損に至るためと考えられる。For this reason, it is necessary to firmly clamp the window glass 1 between the core 3 and the cavity 4 of the mold 5, but there is a problem in that the window glass 1 is easily damaged by the force of this tightening. This is because, especially when the window glass 1 is bent, it is difficult to improve the processing accuracy, and the bending shape inevitably varies depending on the individual product, so when the mold 5 is tightened, the window This is thought to be because concentrated stress is applied to the glass l, leading to breakage.
一方、ガスケット形成材料としては、合成樹脂の溶融物
や、成形型５内で反応して合成樹脂となる流動性合成樹
脂原料混合物が用いられている。On the other hand, as the gasket forming material, a molten synthetic resin or a fluid synthetic resin raw material mixture that reacts in the mold 5 to become a synthetic resin is used.
前者としては、例えば軟質塩化ビニル系樹脂などが採用

It becomes easier to invade contact surfaces,
It has become more difficult to prevent outbreaks such as Paris.

ガラスの製造法を提供することにある。In addition, when using a fluid synthetic resin raw material that reacts to become a synthetic resin (the so-called R2H method), the molding pressure may be low, but since it involves a reaction within the mold 5, it is necessary to remove air bubbles and ``Object of the Invention'' The purpose of the present invention is to reduce the molding pressure and prevent the occurrence of flakes by specifying the material for forming the gasket. An object of the present invention is to provide a method for manufacturing a window glass with a gasket, which can be easily formed.

。``Structure of the Invention'' The present invention includes arranging a window glass in a mold, forming a gasket molding cavity space between the peripheral edge of the window glass and the inner surface of the mold, and adding a gasket forming material to the cavity space. The method for producing a gasketed window glass in which plastisol is used as the gasket forming material, and the plastisol is injected into the cavity space and then heated and solidified.

きな窓ガラスへのガスケットの成形も容易になされる。"Effect" Plastisol is in a liquid state with a lower viscosity than a molten synthetic resin, so it can be easily injected into a mold even at low molding pressure, thereby reducing the occurrence of flakes, etc. Can be done. In addition, since it is solidified by heating after being injected into the mold, there is no need to perform heating, stirring, etc. during injection, making the molding operation extremely easy. Furthermore, the gasket can be injected even at a low molding pressure and does not involve reactions such as stirring or solidification during injection, so gaskets can be easily molded into relatively large window glasses.
「発明の実施例」
第１図には１本発明の製造方法を実施するための成形型

れていてもよい。In this mold 5, a heater 8 is embedded in the vicinity of the cavity space B, so that the gasket material injected into the cavity space 8 can be heated by the heater 8. In this example, the heater 8 is buried near the cavity space 8 of the core 3 and is arranged along the path of the cavity space B. However, as a heating means, in addition to the heater 8 described above, a pipe through which a heat medium flows may be buried, or a high-frequency heating electrode may be attached to the inner surface of the mold 5, and various other means can be employed. Also,
In this example, the heater 8 is buried on the core 3 side,
It may be buried on the cavity 4 side, or it may be buried on both sides.

てもよい。In the present invention, plastisol is used as the gasket forming material. Here, plastisol is a material in which fine particles of thermoplastic resin are dispersed in a liquid plasticizer, and when heated, the thermoplastic resin dissolves in the plasticizer and gels, forming a uniform solid resin composition. . A preferred example of plastisol is a liquid plasticizer composition in which fine particles (particle size 1 to 5 ps) of vinyl chloride resin (homopolymer or copolymer) are dispersed. In addition to the above-mentioned components, a stabilizer, a coloring agent, etc. can be added to the plastisol. Further, the viscosity may be adjusted to an appropriate level in consideration of the sealing property at the contact surface between the mold 5 and the window glass l, or a foaming agent may be used in combination to compensate for molding appearance defects.
第１図に示すように、成形型５内に窓ガラス１を配置し

拌を行なわずにそのまま射出し注入するだけでよい。As shown in FIG. 1, with the window glass 1 placed in the mold 5, plastisol as described above is injected into the cavity space B through the gate 7. In conventional manufacturing methods, for example, when using a synthetic resin melt,
Heating is required during injection to maintain the molten state.
Further, when using a fluid synthetic resin raw material that undergoes one reaction to become a synthetic resin (so-called RIM method), it is necessary to stir and mix at the time of injection. However, in the method of the present invention, heating or stirring during injection is rather undesirable because it promotes gelation of plastisol, and it is sufficient to simply inject the plastisol as it is without heating or stirring.

である。Since plastisol is a liquid with low viscosity, the molding pressure (pressure at the time of injection) can be low. Therefore, even if the sealing performance at the contact surface between the window glass 1 and the mold 5 is not very strict, it will not cause the formation of particles such as Paris. Occurrence can be prevented. In addition, since heating is not required during injection and reaction conditions such as stirring and mixing are not particularly required, injection can be performed with a relatively simple operation, and it is suitable for manufacturing gaskets for large window glasses 1.

After forming the gasket 2 in this manner, the window glass 1 and the gasket 2 are taken out from the mold 5, thereby obtaining a window glass with a gasket.

のであってもよい。The window glass l to which the present invention is applied includes a single piece of normal glass, a laminated glass made by bonding two pieces of glass with an interlayer film such as polyvinyl butyral, and one side of the glass or laminated glass coated with polyurethane resin or polyester. Various types of glass can be used, including balayers, which are laminated sheets of resin, etc., and double-glazed glass, which is made by laminating two sheets of glass with a gap between them, sealing the surroundings, and filling the gap with dry air or nitrogen gas. Moreover, these glasses may be air-cooled strengthened.

Even if it is not, the occurrence of Paris etc. can be prevented. Further, since operations such as heating and stirring and mixing are not required during injection, gaskets for large window glasses can be easily manufactured.
