It is about the method.

These resin guides 3 are bonded or fitted onto the periphery of the window glass 2 to be integrated. In this conventional method for manufacturing a window glass I with a resin guide, it is necessary to mold and paint the resin guide 3 in advance, and it is also necessary to adhere and fit the resin guide 3 to the window glass 2 as described above. There is.

１１１１号公報）。However, in recent years, as a method for joining an edging molded member to the peripheral edge of a plate-shaped body, the peripheral edge of the plate-shaped body is brought into contact with the inner periphery of a cavity formed at the joint of the upper mold and the lower mold. A method has been proposed in which a edging member is integrally formed on the peripheral edge of a plate-shaped body by inserting the plate-shaped body into the cavity and injection-molding a resin into the cavity (for example, Japanese Utility Model Application No. 56-171
No. 213, JP-A-57-1737 and JP-A-57-1
1111).

強度を有する縁取り部材を得ることがむづかしかった。(Problems to be Solved by the Invention) Conventional injection molding methods include injection molding of molten resin and reaction injection molding (RIM) using urethane resin. Due to these limitations, it has been difficult to obtain a edging member that has sufficient strength in terms of weather resistance, abrasion resistance, etc.
また、上記射出成形法では、パリ等の関係で型締め圧を
大きくしなければならず、そのため板状体に加わる圧力
が大きくなること、更には樹脂の射出圧力が直に板状体
にあたるため、板状体が割れるという問題点を有してい
た。In addition, in the injection molding method described above, the mold clamping pressure must be increased due to Paris etc., which increases the pressure applied to the plate-shaped body, and furthermore, the injection pressure of the resin hits the plate-shaped body directly. However, there was a problem in that the plate-like body broke.

And the aesthetic appearance was inferior. That is, it has been difficult to perform surface treatment on the edging member after molding.

We aim to provide the following.

In a method of molding a edging member on the peripheral edge of the plate-shaped body by exposing the peripheral edge of the plate-shaped body into the cavity through a sealing member and injecting resin into the cavity, the edging member is formed by an upper mold and a lower mold. The invention is characterized in that the reinforcing material is placed on the peripheral edge of the plate-like body in the cavity and the mold is clamped, and then the injection molding is performed.

Short fibers may be used as a molded body, continuous long fibers may be directly wound around a predetermined position on the outer periphery of a plate-like body, or they may be wound around another mold to form a preform body.

キャビティの成形面に表面用塗布剤を塗布したのち射出
成形するとよい。表面用塗布剤としては例えばゲルコー
ト剤を塗布し乾燥させた後に射出成形する。If it is desired to improve the surface strength of the edging member, injection molding may be carried out after applying a surface coating agent to the molding surface of the mold cavity. As a surface coating agent, for example, a gel coat agent is applied, dried, and then injection molded.
表面用塗布剤は、耐摩耗性、耐候性、耐化学薬品性等目
的に応じて１つ以上の特性を有する塗布剤を使用する。As the surface coating agent, a coating agent having one or more properties such as abrasion resistance, weather resistance, and chemical resistance depending on the purpose is used.
具体的には、ポリウレタン樹脂、アクリル樹脂、ポリア
ミド樹脂エポキシ樹脂系塗料が用いられるほか、ゲルコ
ート剤例えばビニルエステル系樹脂などが用いられる。Specifically, polyurethane resins, acrylic resins, polyamide resins, epoxy resin paints, and gel coating agents such as vinyl ester resins are used.
これらの塗布剤の塗布厚は目的に応じて選択されるが、
これらを塗布することによって上型と下型との合せ面（
見切面）をシールすることができるため、型締め圧を低
くすることができる。The coating thickness of these coating agents is selected depending on the purpose, but
By applying these, the mating surface of the upper mold and lower mold (
Since the parting surface) can be sealed, mold clamping pressure can be lowered.
塗布剤はスプレーガン塗装によって通常塗布される。The coating is usually applied by spray gun application.
塗布剤によっては、塗布する前にキャビテイ面への離型
剤の塗布を省略できるが、通常は塗布前に離型剤を塗布
する。離型剤の塗布は、通常の射出成形時のものと同様
でよい。Depending on the coating agent, it is possible to omit applying a mold release agent to the cavity surface before coating, but usually a mold release agent is applied before coating. The mold release agent may be applied in the same manner as in normal injection molding.
樹脂の射出成形に際しては、一方から成形型のキャビテ
ィへ樹脂を圧入する方法でもよいが、キャビティ内を減
圧状態にして射出するとよい。In injection molding of the resin, the resin may be press-fitted into the cavity of the mold from one side, but it is better to inject the resin with the inside of the cavity in a reduced pressure state.
