摘要： A method of producing a laminated structural molding formed from molded resin and an outer layer of facing material. The method comprises the step of initially placing the facing material in a mold. Molten resin is injected into the mold. The resin is spread throughout the mold by locating mold sections adjacent each other at a set compressive force. The partially assembled molding is then subjected to a cooling process in which the compressive force to which the molding is exposed is reduced so that the force is greater than zero but less than the compressive force used to spread the resin. The mold sections do not retract or move during the reduction in the compressive force. The cooling process is performed just before or after the completion of the spreading of the resin. In this way, the damage to the facing material of the molding is kept to a minimum.

摘要： A die for injection molding for charging molten resin onto a surface material set on the cavity surface is disclosed. The die comprises direction changing means for changing the direction of flow of the molten resin charged through the gate to directions along the surface of the surface material. The direction changing means may be a substantially conical direction changing member for changing the direction of flow of the molten resin. Since the direction changing means can change the direction of flow of the molten resin charged into the die, which is completely closed or slightly open, to directions along the surface of the surface material, the molten resin does not strike the surface material. Thus, damage to the surface material in the neighborhood of the gate can be prevented, and the surface material can be protected against the collision with molten resin which is at a high temperature and under a high pressure.
摘要翻译：公开了一种用于将熔融树脂填充到设置在空腔表面上的表面材料上的用于注射成型的模具。模具包括方向改变装置，用于改变通过浇口填充的熔融树脂的流动方向沿着表面材料表面的方向。方向改变装置可以是用于改变熔融树脂的流动方向的大致圆锥形的方向改变件。由于方向改变装置可以将填充到完全关闭或稍微打开的模具中的熔融树脂的流动方向改变为沿着表面材料的表面的方向，所以熔融树脂不会撞击表面材料。因此，能够防止在栅极附近对表面材料的损伤，可以防止表面材料与高温高压的熔融树脂的碰撞。
