Abstract

PURPOSE: To control the expansion and deformation of a molded body and to prevent it from failure when inserted into cooling metal molds by a method wherein when the molded substance which has been made to foam and molded in the metal molds for the exclusive use of heating moves into the metal molds for the exclusive use of cooling, the metal molds for heating are opened stepwise.
CONSTITUTION: Preliminary foaming particles are filled in the metal modls 1, 2 for the exclusive use of heating and the particles are made to foam and fused by a heating medium such as steam etc. to obtain a molded body 3. Then, the movable mold 2 of heating metal molds is moved by a distance of 1W50mm, for instance, and kept as it is for a specified time. By this method the molded substance 3 is expanded only in the direction where the metal molds 1, 2 are opened. After that the molded body 3 is moved to the molds 4, 5 for the exclusive use of coolig. Additionally, when the molds 1, 2 are opened stepwise, it is preferable to reduce cooling time by blowing fluid such as air etc. on the surface of the molded body 3.
