の上面に裏型２を載置して表型１の上面で製品の
表面を形成し、裏型２の下面で製品の裏面を形成
するようにした合成樹脂成形装置Ａにおいて、略
板状の発泡材を芯材５とし、同芯材の上下面を、
ガラス繊維層Ｇを内側にカーボン繊維層Ｃを外側
にして積層被覆し、各繊維層Ｇ，Ｃに熱硬化性の
合成樹脂を含浸硬化させることにより、上記芯材
５と各繊維層Ｇ，Ｃとを接着して一体の裏型２を
構成し、同裏型２の下面だけをゲルコート層ｇで
被覆してなる合成樹脂成形用の裏型構造。 A synthetic resin material is injected into a top mold 1 with an open top, and a back mold 2 is placed on top of it, so that the top surface of the front mold 1 forms the front surface of the product, and the bottom surface of the back mold 2 forms the back surface of the product. In the synthetic resin molding apparatus A, a substantially plate-shaped foamed material is used as the core material 5, and the upper and lower surfaces of the concentric material are
The core material 5 and each fiber layer G, C are laminated and coated with the glass fiber layer G on the inside and the carbon fiber layer C on the outside, and each fiber layer G, C is impregnated with a thermosetting synthetic resin and cured. This is a back mold structure for synthetic resin molding, in which an integral back mold 2 is formed by bonding the two, and only the lower surface of the back mold 2 is covered with a gel coat layer g.
