を特徴とする射出成形用金型。 A runner gate is inserted between the dividing surfaces of the fixed side cavity die and the movable side core die to guide the molten resin from the sprue to the cavity, and a cutting block that forms the cutting edge of this gate is used to cut the core die when cutting the gate. In an injection mold that is attached to a core die so as to be slidable in a direction substantially orthogonal to the movable direction, the dividing surface between the cutting block and the cavity die is formed to be inclined with respect to the direction in which the cutting block moves during gate cutting. An injection mold characterized by:
