ABSTRACT:
A two-stage injection molding machine having a pressure sensor device is proposed. The two-stage injection molding machine includes an injection part having an injection cylinder, a driving unit, and an injection rod installed in the injection cylinder; a metering part for feeding plastic material to the injection cylinder of the injection part; and a loadcell installed between the injection rod and the driving unit, wherein pressures in the injection cylinder during the feed metering, injection, and packing processes are detected via the loadcell and the pressure sensor rod. As a result, an accurate pressure feedback control is implemented to achieve high precision injection molding quality. And with the two-stage injection molding machine having such a simple structural design, occurrence of signal distortion and delayed response is prevented.
