ABSTRACT:
A nozzle contact device for guiding and clamping the injection nozzle for an injection unit of an injection molding machine onto an injection mold includes a linear drive for moving the injection unit back and forth, and a guide carriage which can be driven by the linear drive, with the guide carriage being articulated to the injection unit. The invention is characterized in that the axis of rotation of the articulation between the guide carriage and the injection unit extends horizontally, and that this axis of rotation and the injection axis are arranged on planes which are parallel to each other, preferably on the same horizontal plane. Rotary joints or flexural joints can be provided. In addition, the rear part of the injection unit, in particular a screw mechanism can be height-adjustable. As a result, the nozzle contact force is introduced into the injection unit in the absence of a bending moment. No tilting is caused between the injection nozzle and the sprue bush of the injection mold.
