APPARATUS FOR INJECTION MOLDING SYNTHETIC RESIN

摘要

The present invention relates to an apparatus for injection molding a synthetic resin, and comprises: an injector for transferring while melting pellets which are supplied in one direction; a nozzle, which is installed on a front end of the injector, for injecting molten resin that is melted into a gel form; a mold which is filled with the molten resin in the gel form that is injected through the nozzle; a hydraulic pressure application means for applying hydraulic pressure to the mold for clamping the mold, and for applying hydraulic pressure also to the injector for injecting the molten resin into a cavity of the mold; and a gas supply and exhaust means for filling gas at a set pressure, which corresponds to a range within which moisture contained in the molten resin that is injected is not gasified, inside the cavity before the molten resin is injected into the cavity of the mold, thereby providing effective mass production of quality injection molded products.
