ダカツト処理構造。 A slide core forming an undercut portion of the molded product is provided with a first slide core located at the upper part of the extrusion block, and a slide core provided adjacent to the first slide core, the first slide core and the first slide. In an injection molding mold that is divided into a second slide core that slides in the vertical direction with respect to a movable mold located outside the core, the first slide core and the movable mold are connected to the second slide core. Recesses are formed in each of the sliding surfaces, and the second slide core is always urged toward the first slide core by a spring, and the second slide core is always biased toward the first slide core by the relative positions of the first and second slide cores. 1. An undercut treatment structure for an injection mold, characterized in that a lock pin is attached to engage either a slide core of the mold or a recess of a movable mold.
