MOLDING METHOD OF FOAMED THERMOPLASTIC RESIN AND METAL MOLD THEREFOR

摘要

PURPOSE:To facilitate release of a molded article without using an eject pin by performing molding by means of dies one of which is concave in shape and the other of which is nearly flat. CONSTITUTION:On the occasion of molding of the foamed thermoplastic resin, the preliminarily foamed resin is filled up for molding in a cavity formed by using the die 3 having a concave part on one side and the die 2 whose front surface 4 is mostly plane on the other. It is preferable that teflon coating is applied to a part or the entire part of the molded article of the dies. Moreover, it is also preferable that the concave die is provided with an exhaust system and is filled with the foamed resin preliminarily foamed.
