出成形用金型。 In an injection mold for forming a molded product having an undercut, a slide core that can move forward and backward in the cavity direction is fitted into the injection mold, and a recess for the undercut is formed on one side of the slide core. The opposite side surface is formed with a tapered surface that comes into close contact with the mold when the slide core retreats, and the slide core is configured such that the tapered surface side tilts toward the mold tapered surface side when the slide core moves forward. An injection mold characterized by a slide core pivotally connected to an extrusion rod.
