射出成形金型。[Scope of Claim for Utility Model Registration] In an injection mold for producing a molded product including thick parts such as cylindrical bosses and reinforcing ribs by injecting resin etc. into the space formed by one mold and the other mold. Using a cooling pin that is movably disposed inside the mold and forcibly cools the thick part of the molded product, the mold is opened slightly after the primary cooling, and the cooling pin is blown onto the thick part. An injection molding mold characterized by having an outlet close to each other and blowing cooling air into this thick wall part for cooling.
