とを特徴とする射出成形用金型。 An injection mold that has multiple movable cores, molds the molded product into a concave shape in the movable core, and inserts it into the lower cavity so that the ejector pin does not come into direct contact with the molded product during molding. After molding, the movable core retreats and the ejector plate is pushed out. At the same time, the ejector pin moves upward and presses the molded product. An injection mold that extrudes a molded product after contact and leaves no ejector pin marks on the molded product.
