金型。 A cavity is formed by a stationary mold and a movable mold, and after injecting and molding synthetic resin into this cavity, the movable mold is moved, and the product molded in the cavity is moved. In a synthetic resin injection mold that is configured to protrude from an ejector pin provided in the mold, a recess is formed in the wall surface of the movable mold in which the end of the ejector pin is positioned, so that the ejector pin can be pushed out during molding. A mold for synthetic resin injection molding, characterized in that the end portion is substantially flush with the bottom surface of the recess, and the ejector pin is configured to press a thick wall portion formed in the recess when the product is ejected.
