Abstract

PURPOSE: To obtain a uniform foaming product with high productivity by enabling the primary foaming in a short period under high temperature condition by using a pot type die.
CONSTITUTION: A die comprises a punch 1 having a convex cross section, dies 3, 4 of concave cross section having a pot 6 located at the opposite of the ram 5 of the punch, wherein the die is divided into two parts 3, 4 by the parting face 7 in parallel to the bottom of the pot. The cavity 8 is provided for corresponding to the external form of the plastic to be molded along the parting surface 7, opening the resin runner 9 located between the cavity and the pot bottom face. In molding thereof, a fixed amount of the foaming stock material 2 is filled into the pot 6, and the ram 5 of the punch 1 is fitted with the pot for pressing. The material melted and softened by the press is entered into the cavity 8 after passing through the runner 9 for the primary foaming. The spare molded product foamed primarily allows to secondary foam molding within the finished die.
