Abstract
A plastics injection molding machine with an injection unit has an injection unit housing as central part of the injection unit, a plasticizing cylinder connected to the injection unit housing, a screw which is supported in the plasticizing cylinder for rotation to prepare injection material and for displacement to effect the injection stroke in axial direction, drive motors coupled to and generating the rotation and axial movements of the screw and supported on the injection unit housing via a motor flange, and an injection force measuring device for determining the injection force applied by the screw when executing its injection stroke, wherein the injection force measuring device includes at least one tensile force sensor which is integrated in the injection unit housing in such a manner that the reaction force of the injection force, as generated by the injection force and introduced via the motors and the motor flange into the injection unit housing, is detectable.
