摘要： A screw is incorporated in a heating barrel, and the tail end of the screw is rotatably supported by the front surface of an intermediate plate. Behind the intermediate plate, two linear motor units are connected in parallel and arranged around the shaft of the screw to form axial symmetry. The output shafts of the linear motor units are connected to the tail end of a driving shaft through a common connecting arm, and the leading end of the driving shaft is fixed to the rear surface of the intermediate plate. Each of the liner motor units is constituted by a plurality of voice coil linear motors connected in parallel. Each of the linear motor units can be independently controlled. Voice-coil linear motors to be used are selected according to the type of product to be manufactured.

摘要： A screw is incorporated into a heating barrel. A ball screw is connected to a rear end portion of the screw through a load cell, and a servomotor for injection is connected to the ball screw. First, the heating barrel is retreated and separated from a mold, and the screw is moved to the half stroke position. After the screw is advanced for a preset period of time, the servomotor is stopped by automatic decompression to detect an output of the load cell. Similarly, after the screw is retreated for a preset period of time, the servomotor is stopped by automatic decompression to detect an output of the load cell. An average of outputs of the load cell after the screw advances and retreats is calculated and considered to be an output of the load cell under no-load conditions, thereby performing zero adjustment of the load cell.
