The purpose of the present invention is to provide a large molding machine equipped with a mold close retaining structure which allows a product to be molded in a cavity of an inner space of a mold (214) in state in which the mold (214) with the cavity for molding a product in the inner space is closed by being installed at a machine body (210). The large molding machine comprises: a pair of mold plates (216) which are arranged at the machine body (210) in order to face each other and are formed in order to be close to or be apart from the machine body (210); a pair of motors (212) which are respectively installed at the machine body (210) in order to be arranged at the outside of a pair of the mold plates (216); a pair of transmission link parts (218) which are arranged at the outside of a pair of mold plates (216) by allowing one end to be connected to a motor shaft of the motor (212); a pair of retaining link parts (224) which are respectively arranged at the outside of the mold plate (216) by allowing one end to be connected to the transmission link part (218); and a retaining unit (220) which applies elastic force supporting the mold (214) by pressurizing the mold (214) inserted between a pair of mold plates (216) by being connected to the mold plate (216) and the retaining link part (224) when molding materials are molded by inserting the molding materials into the cavity of the inner space of the mold (214).
