成形用金型。 A movable mold is equipped with a slide core and an inclined extrusion block, the slide core is provided with a molding part for forming a first stage undercut part on the terminal side, and the inclined extrusion block is provided with a molding part for forming a second stage undercut part located away from the terminal side. A molding section is provided for molding each part, and the first stage undercut part is demolded by the movement of the slide core, and the entire molded product is demolded by interlocking the inclined extrusion block with the extrusion plate. In the injection mold, the inclined extrusion block is moved from the mold in which it was housed due to the shrinkage force or restoring force generated in the molded product that is deformed when the first stage undercut portion is removed from the mold. An injection mold characterized by having a configuration in which the molds are separated.
