体７に緩衝材４の上端部を当接せしめている。 These cushioning materials 4 and 5 are made of elastic materials such as silicone rubber, Teflon rubber, and EPDM with a shore hardness of 60 to 90, and have a rectangular cross section.
It forms a band along the periphery of the. The cushioning material 5 of the lower mold 2 is applied to the molding surface 2a of the lower mold 2 by a predetermined dimension.
The cushioning material 4 of the upper mold 1 is fixed to the lower mold 2 so as to protrude from the upper mold 1, and the cushioning material 4 of the upper mold 1 is attached so as to be movable in and out of the upper mold 1 so that its upper end faces the space 6 formed in the upper mold 1. An elastic body 7 having a shore hardness of 50 or less is provided within the portion 6, leaving an escape space 6a, and the upper end of the cushioning material 4 is brought into contact with this elastic body 7.
以上において、板ガラスＧの周縁部にモールを
形成するには、第１図に示すように上型１と下型
２を開いた状態で成形面１ａ，２ａ間に板ガラス
Ｇの周縁部を臨ませ、次いで第２図に示すように
上下の型１，２を閉じる。 In the above, in order to form a molding on the peripheral edge of the glass plate G, as shown in FIG. Then, as shown in FIG. 2, the upper and lower molds 1 and 2 are closed.
すると緩衝材４，５が板ガラスＧの上下面に当
接し、キヤビテイ３と外部とをシールする。ここ

圧に応じて出没可能となつているので、板ガラス
Ｇの形状に応じて出没動し、板ガラスＧには常に
一定の圧力でもつて緩衝材４，５が当接する。 Then, the cushioning materials 4 and 5 come into contact with the upper and lower surfaces of the glass plate G, sealing the cavity 3 and the outside. Here, the cushioning material 4 provided on the upper mold 1 can move in and out depending on the contact pressure with the plate glass G, so it moves in and out according to the shape of the plate glass G, and even if a constant pressure is applied to the plate glass G. The cushioning materials 4 and 5 come into contact with each other.
この後、キヤビテイ３内樹脂材料を注入し、硬

も優れた製品が得られる。(Effects of the invention) As explained above, according to the invention, the cushioning material provided in the molding mold is made to protrude and retract from the mold according to the shape of the glass plate, so that a gap is created between the cushioning material and the glass plate. A product can be obtained in which the boundary line between the glass and the molding is regular and continuous, the appearance is good, and the cushioning material is not crushed.The product has good appearance and excellent adhesive strength.
また、逃げ空間があるので、緩衝材が押されて
弾性体が圧縮されても、弾性体の弾発力が急激に
高まることもなく、弾性体の形状復元力に応じた
ほぼ一定の押圧力がガラス面に加わる。 In addition, because there is an escape space, even if the cushioning material is pressed and the elastic body is compressed, the elastic force of the elastic body does not increase suddenly, and an approximately constant pressing force corresponding to the shape restoration force of the elastic body is applied to the glass surface.
