成形用金型。[Claims for Utility Model Registration] An injection mold for molding a synthetic resin molded product having a protrusion with an undercut portion formed on the surface, and opening and closing in the horizontal direction to automatically drop and take out the molded product when the mold is released. The movable mold is provided with a plurality of extrusion cores for forming the protruding portion, a first extrusion plate is provided behind the movable mold with a gap therebetween, and a first extrusion plate is provided behind the first extrusion plate. A second extrusion plate is disposed, an extrusion pin for mold release that is fitted into the movable mold along the mold opening/closing direction is fixed to the first extrusion plate, and a mold opening/closing pin is fixed to the second extrusion plate. A supporting member that is inserted into the movable mold along the direction and supports each extrusion core is fixed, and a second extrusion plate is moved forward relative to the movable mold behind the second extrusion plate. In the mold to which the extrusion rod is arranged, a biasing means is disposed between the movable mold and the second extrusion plate for biasing the second extrusion plate backward so as to separate it from the movable mold. An injection mold characterized by:
