。[Scope of Claim for Utility Model Registration] (1) Molten resin is flowed from the runner into the cavity through a submarine gate formed in the movable mold, and the solidified resin in the cavity is ejected by an ejector pin, thereby making the movable In an injection mold that is released from the mold,
An injection molding mold characterized in that a protruding position of the ejector pin is set close to an opening to a cavity of a submarine gate. (2) The injection molding mold according to claim 1 of the utility model registration claim, characterized in that the distance between the line of action of the ejector pin and the side surface of the cavity where the submarine gate is opened is set to be small. .
