形用金型。[Scope of Claim for Utility Model Registration] In an injection mold for molding a molded product having a thick wall portion or an uneven thickness portion, a valve body is provided opposite to a molding portion of a cavity that molds the thick wall portion or uneven thickness portion. A gas injection nozzle having a gas injection nozzle is provided, and the tip of the valve body is arranged so as to protrude into the molded part from an injection port formed facing the molded part of the cavity. For injection molding, characterized in that the injection port is provided so as to be able to move forward and backward to open and close, and is configured to inject gas into the molded part of the cavity through the injection port when the valve body retreats due to the pressure of the gas. Mold.
