たことを特徴とする射出成形用金型。 A box-shaped cutting block is disposed in the mold so as to be slidable in a direction intersecting the mold closing direction, and a cutting blade having a predetermined shear angle is formed inside the tip wall of the cutting block. contains a first slide core that slides on the inner surface of the cutting blade to form a gate, and a second slide core that slides on the inner bottom surface of the cutting block to form a runner,
The first and second slide cores are engaged at their cam surfaces, each is biased by a spring in the direction of retreating from the molding position, and is moved forward and backward toward one side of the mold in the mold closing direction. An injection molding die characterized in that a cam member for sliding the cutting block and the second slide core is provided.
