成形品の成形金型。 The tip is pre-split to open by its own elasticity to form a split mold part for forming the undercut part, and a forming pin with a tapered part that becomes thicker on the split mold side is attached to the base of the split mold part. The molding pin is slidably inserted into a holding hole that matches the outer mold of the split mold part formed in the template on the side where the extrusion pin is provided, and the split mold part is pulled into the holding hole during molding. A molding die for a molded product having an undercut portion configured to drive a molding pin in conjunction with an extrusion pin so that the split mold portion and the tapered portion protrude from the holding hole during extrusion.
