Injection molding machine for two-material molding and method of controlling the same

摘要

In an injection molding machine for two-material molding including two sets of injection units 11, 12 that plasticize different resin materials and injection-fill the materials, a mold clamping unit is a hydraulic mold clamping unit that mold-clamps three sets of die plates 2, 3, 9 simultaneously, a movable die plate opening and closing unit 14 is a movable die plate opening and closing unit driven by an electric motor, a rotational die plate opening and closing unit 15 is a rotational die plate opening and closing unit 14 driven by an electric motor, and a rotating unit for the rotational die plate 9 is a rotation driving unit driven by an electric motor attached to a reversal pedestal 7.
