成されたことを特徴とする射出成形用金型。 In an injection mold for molding a product that has a structure in which a fixed core pin and a rotating core pin are combined and has a threaded portion on the inner surface, the fixed core pin is made slidable in the axial direction relative to the rotating core pin. At the same time, a sliding piece energized by a spring is loaded into the through hole in the cavity bush into which the tip end shaft of the fixed core pin is inserted during mold clamping, and the sliding piece is always pressed by the sliding piece when the mold is clamped. The fixed core pin is pressed down to eliminate the gap between the abutting portions of the fixed core pin and the rotating core pin, and when the mold is opened, the fixed core pin is slid in the axial direction by the required amount relative to the rotating core pin, and the fixed core pin and the rotating core pin are separated. An injection mold, characterized in that the mold is configured to create a required amount of clearance at the abutting portion of the mold.
