る射出成形金型の二段押出構造。In the injection mold, one end of a cylindrical sleeve is inserted directly below the cavity of the movable mold so as to be slidable along the axis of the sleeve, and the other end of the sleeve protrudes through the movable mold and is inserted into the extrusion plate. A sleeve pin is fitted into the cylindrical interior of the sleeve along one axis of the sleeve, and the other end of the sleeve pin protrudes through the movable mold and the extrusion plate. It is fixed to the mounting plate,
Furthermore, an ejector turbine is fitted inside the sleeve pin and is slidably attached along the axis of the sleeve pin, and an extrusion pin is attached to the ejector turbine at right angles to the axis of the ejector turbine. Both ends of the extrusion pin abut on and pass through the lower edge of an oblong through hole formed along the axis of the sleeve pin, and the extrusion pin extends through the sleeve around the outer periphery of the sleeve pin. In this case, the push-out pin contacts the upper end edge of a through hole formed in an oblong shape along the axis of the sleeve, and the push-out pin can freely advance and retreat within the through hole of the sleeve pin and the through hole of the sleeve. Two-stage extrusion of an injection mold, characterized in that extrusion of the molded product and extrusion of a part of the sprue are performed in two stages by creating a shift in extrusion timing between the sleeve and the ejector turbine. structure.
