Abstract:
1. A nozzle contact device for guiding and pressing an injection nozzle of an injection unit of an injection molding machine against an injection mold, comprising: a linear drive; and a guide carriage articulated to the linear drive and directly operated by the linear drive for moving the injection unit in a direction of an injection mold for injection of material along an injection axis from an injection nozzle into the injection mold, said guide carriage being articulated to the injection unit for rotation about a horizontal axis of rotation, wherein the axis of rotation and the injection axis extend on horizontal planes in parallel relationship to one another, wherein the linear drive includes an axially fixed but rotatably supported screw shaft, and a screw nut secured non-rotatably to the guide carriage, further comprising a spring plate, which is articulated to the guide carriage and restrained against rotation in relation to the linear drive, and at least one spring arranged between the ball nut and the spring plate.
