ABSTRACT:
An injection molding machine includes a guide coupling for transmitting a linear movement of a ball screw mechanism, and a screw coupling for transmitting rotary movement. A washer-type load cell including an inner tubular portion having first and second ends, an outer tubular portion, and an intermediate distortion portion, is positioned between the guide coupling and the screw coupling to detect a pressure applied to the screw coupling. The inner tubular portion of the load cell and a pair of bearing portions positioned at the first and second ends of the inner tubular portion are secured to the screw coupling by a bearing nut, and the outer tubular portion of the load cell is secured to the guide coupling. This arrangement allows screw pressure to be applied to the inner tubular portion through both the screw coupling displacing relative to the guide coupling and the bearing portion, while the outer tubular portion is positioned-regulated by the guide coupling. The output of the load cell is unaffected by either predetermined loads caused by initial tightening of the structure or the guide coupling, and is proportional to the screw pressure.
