PURPOSE:To provide an injection molding machine for a disk substrate capable of improving a yield of the disk substrate by a method wherein mixing of foreign matter such as a resin scrap or the like in the disk substrate is lessened when the disk substrate of an optical disk or the like is injection molded. CONSTITUTION:When a grip part 16 B of a disk carrying means 16 is clamped with molding metal molds 26A, 26B, electrostatic air is jetted to the grip part 16B from an air blower, and foreign matter such as a resin scrap or the like which adheres to the grip part 16B is removed. Besides, the electrostatic air having passed by the grip part 16B is drawn by suction from a suction opening together with the resin scrap or the like. Therefore, the foreign matter such as the resin scrap, chips, etc., which is adhered to the grip part 16B is effectively removed, and besides insides of the molding metal molds 26A, 26B are not contaminated with the resin scrap or the like. |
