防止装置。 In a pre-plastic injection molding machine that plasticizes resin in a plasticizer and supplies it to an injection device through a resin flow path, and injects the plasticized resin into a mold from an injection nozzle in the injection device, a valve body is installed in the resin flow path. A valve seat is provided, and a closing drive device is attached to the valve body, which forcibly presses the valve body against the valve seat and closes the resin flow path when resin is injected into the mold from the injection nozzle. A backflow prevention device for a pre-plastic injection molding machine.
