Synthetic resin foam mold, method for producing synthetic resin foam molded article using the mold, and synthetic resin foam molded article molded by the production method

摘要

The present invention provides a synthetic resin foaming molding die, a manufacturing method of a synthetic resin foaming molded article using the molding die, and a synthetic resin foaming molded article molded by the manufacturing method, which can prevent generation of a large-size void(s). The molding die (10) comprises an upper die (16) and a lower die (12) and having a cavity (29) defined by the upper die and the lower die, and a parting line 22 (communicating portion) communicating the cavity (29) and an ambient air. A rod-like member (24) is provided in fluid passage to allow the synthetic resin foaming material to flow to the parting line (22), in a protruding manner from the cavity surface.
