に構成されたことを特徴とする成形用金型。[Scope of Claim for Utility Model Registration] A molding die consisting of a fixed die and a movable die, which is provided with a slide core, an extrusion rod that is driven in a direction protruding from the mold surface, and an extrusion block having a first guide surface fixed to the tip and inclined with respect to the extrusion direction of the extrusion rod;
a slide extrusion block that is held by the extrusion block and has an undercut surface that forms a wide undercut portion together with the slide core and is movable while being guided by the first guide surface; and a second guide surface of a predetermined length that engages with the slide extrusion block and extends parallel to the extrusion direction of the extrusion rod, the slide core being moved when the molded article is released from the mold. When the extrusion rod is driven, the slide extrusion block is guided by the second guide surface and moved a predetermined distance, and then the engagement with the second guide surface is released, and the slide extrusion block is moved by the drive of the drive means. 2. A molding die, characterized in that the molding die is configured to move while being guided by the first guide surface to release the molded article from the undercut surface.
