PROBLEM TO BE SOLVED: To provide a resin molding apparatus capable of molding a resin in uniform quality without lowering productivity. SOLUTION: This resin molding apparatus has a pot 1 receiving the supply of a granular molding material, the resin passage 5 provided between the pot 1 and a cavity 4 and the injection plunger 3 provided to the pot 1 so as to be freely driven to advance and retreat and advanced to pressurize the molding material in the pot 1 and the molding material in the pot 1 is pressurized by the injection plunger 3 to be compressed and subsequently pressurized by the injection plunger 3 to be injected into the cavity 4. A plurality of pots 1 are provided and the injection plunger 3 is provided to each of the pots 3 and a drive part 26 pressing a plurality of the injection plungers 3 at the same time to advance them is provided. A pressure adjusting means 30 for absorbing the irregularity of the pressing force to the molding material by each of the injection plungers 3 is provided between each of the injection plungers 3 and the drive part 26. |
