PURPOSE: An injection mold to discharge gas is provided to prevent a solidified material from remaining in a hole to discharge the gas in a core and to reduce the frequency for cleaning the hole when molding is finished. CONSTITUTION: An injection mold (1) to discharge gas comprises a first template (3), a second template (5), a gas discharging core (7), and an extracting rod (9). The first template includes one side cavity surface (11) molding one side shape of an injection molded product. The second template includes the other side cavity surface (12) in the opposite side of the one side cavity surface to mold an opposite side shape and forms a cavity with the one side cavity surface. The gas discharging core allows gas generated inside the cavity in the injection molding to discharge with a melting material which is injected into the cavity. The extracting rod extracts the gas discharging core with the injection molded product from the first template and the second template when the injection molded product is extracted.
