Abstract

A mold for in-mold foam molding of polyolefin-based resin that prevents the occurrence of burrs at the time of molding to control productivity reduction and labor cost rising caused by burr trimming. A mold is configured to mold an insert member including an embedded part to be embedded into a foaming molded body formed from a polyolefin-based resin and a protrusion part protruding from the foaming molded body integrally with the foaming molded body. The mold is provided with an accommodation concave part capable of accommodating the protrusion part and an opening/closing part capable of opening and closing a cavity-side opening in conjunction with insertion and extraction of the protrusion part into and from the accommodation concave part such that, while the protrusion part is inserted into the accommodation concave part, and the cavity-side opening is closed.
