置制御装置。 In an injection molding machine, a screw position detector, a screw rearmost position setter, a comparator that compares the detected value with the set value, and a control that controls a directional valve with a flow rate adjustment function based on the signal from the comparator. By introducing the pump discharge oil into the injection ram using the switching valve with a flow rate adjustment function, from the end of the plasticization process or the completion of the sacback,
A screw position control device that corrects screw position fluctuations until the start of the next cycle's injection process.
