MOLDING APPARATUS FOR INJECTION-MOLDED ARTICLES AND MOLDING METHOD

WIPO Patent Application WO/2006/131973

A1

A molded article having been molded by injection molding is sandwiched between a first mold and a second mold and then molded by pressurizing and heating. Thus, the cycle time of an injection molding machine can be shortened without making the mold constitution of the injection molding machine complicated and a large number of molded articles can be pressurized and heated within a short period of time. Thus, peaks, valleys and burrs formed in the molded articles can be taken off while achieving desired properties of the molding materials constituting the molded articles. To achieve these purposes, a first mold (25), on which a molded article having been molded by injection molding is placed, a second mold (45) to be combined with the first mold (25), a mold clamping unit for opening/closing the first or second mold (25, 45) and a heater for heating the molded article are provided and the molded article is sandwiched between the first and second molds (25, 45) and molded by pressurizing and heating.
