INJECTION MOLDING DIE

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 asubstantially 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.
