Abstract:
An injection molding unit for an injection molding machine for the processing of plastic materials and other plasticisable substances, comprising;a carrier block for the accommodation of a plasticizing cylinder; a feed screw which is disposed in the plasticizing cylinder along an axis of injection for the injection of the plasticisable substances into a mold; an injection bridge, which is displaceable axially along the axis of injection and on which the feed screw is mounted so as to be displaceable via at least one bearing element; an electromechanical injection unit for the axial displacement of injection bridge and feed screw through the intermediary of a linear displacement means driven by a first electric drive, the axis of the first electric drive being aligned with the axis of injection; and an electromechanical dosing unit for rotating the feed screw through the intermediary of a second electric drive, the axis of the second electric drive being aligned with the axis of injection, wherein the fist and second electric drives are disposed on the injection bridge on both sides of a parting plane which extends substantially crosswise to the axis of injection and separates the area of influence of the first electric drive from the area of influence of the second electric drive.
