Claims

[Scope of Claim for Utility Model Registration] (1) In a molding mold equipped with an ejector plate for mold release of a molded article equipped with a required number of ejector pins, the ejector pins are communicated with the molding part of the mold. The ejector pin is slidably fitted into the opened pin hole, and the tip of the ejector pin is fitted into a sliding surface of a required length disposed near the communication opening with the molded part side in the pin hole. A molding die characterized in that the central portion of the ejector pin is fitted into a sliding surface of a required length provided near the opening at the other end of the pin hole. (2) Claim (1) characterized in that the central part of the ejector pin is fitted into a sliding surface integrally formed near the opening at the other end of the pin hole. mold for molding. (3) A claim characterized in that the central part of the ejector pin is fitted into the sliding surface of a guide member detachably attached to the vicinity of the opening at the other end of the pin hole. The molding die described in item (1).
