PURPOSE:To mold an injection molded piece having high strength, quality, and dimensional precision without widely degrading productive efficiency. CONSTITUTION:A melting resin 8 is injected into a cavity from an injection passage 9 which opens at a cavity 7 formed in a mold device 1 and a part of the melting resin is extruded to an auxiliary chamber 10 which opens at the cavity from the cavity, and the melting resin in the mold device is cooled and cured. Thereafter, resin bodies 12 and 15 cooled and cured in the injection passage and the auxiliary chamber are cut off simultaneously in the same direction from a resin body 13 which is cooled and cured in the cavity. |
