Claims

[Claims for Utility Model Registration] A pair of split molds; one of the split molds has an end face that forms part of the mold surface in a direction that protrudes from the mold surface when the molded product is released from the mold; a main extrusion member that is driven to the main extrusion member; and a main extrusion member that is provided on one of the split molds and has an end face that constitutes a part of the mold surface and a part of the mold splitting surface, and that extends in a direction protruding from the mold surface and in the opposite direction. a movable sub-extrusion member; a biasing member provided on one of the split molds and urging the sub-extrusion member in a direction to protrude from the mold surface;
and when the main extrusion member releases most of the molded article and the biasing force of the urging member becomes greater than the adhesion force of the molded article to the mold surface, the sub-extrusion member releases the molded article. A molding die characterized in that the molding die is configured to be released from the mold surface.
