る、射出成形金型。 The core member directly above the mold that releases the workpiece from the mold is
A directly above boss pin is provided that is directly connected to the ejector plate and inserted into a through hole provided in the directly above core member and the ejector plate, and the directly above boss pin has a protrusion that protrudes in a direction perpendicular to the axis of the directly above boss pin. A large-diameter recess is formed in a part of the through hole of the ejector plate, and the protrusion is fitted into the large-diameter recess so that the directly above boss pin can be moved a certain distance in the axial direction thereof. The injection mold is further characterized in that a biasing means for biasing the protrusion in a direction opposite to a mold release direction is provided on the boss pin directly above the boss pin.
