Abstract
A pressure detection apparatus of an injection molding machine composed of a drive mechanism and a movable member includes a pressure reception member disposed in the drive mechanism in such a manner as to be movable in a reciprocating direction of the movable member while being guided by a guide member. A ball screw or nut of a ball screw mechanism of the drive mechanism is fixedly attached to the pressure reception member. A load cell is disposed between the drive mechanism and the movable member in such a way as to be fixedly attached to one of a bearing ring retainer facing the movable member and the pressure reception member while abutting the other. The pressure reception member receives stress (load) directed in a rotation direction and arising from the ball screw or nut, thereby preventing imposition of the stress (load) on the load cell.
