NOZZLE CLAMPING DEVICE

摘要

The invention relates to a nozzle clamping device for guiding and clamping the injection nozzle (44) for an injection unit (2) of a injection-moulding machine in an injection-moulding tool comprising a linear drive (47) for alternately moving the injection unit (2) and a guiding carriage (20) which is pivotally connected thereto and driven by the linear drive (47). Said invention is characterised in that the axis of rotation (46) of the hinge joint between the guiding carriage (20) and the injection unit (2) is horizontally arranged and said axis of rotation (46) and an injection axis (45) are arranged on the planes which are parallel to each other, preferably on the same horizontal plane. Articulated or flexible joints are also provided. In addition, the rear part of the injection unit (2), in particular a worm drive (6) is height-adjustable. The advantage of the invention lies in that the introduction of the nozzle clamping force into the injection unit (2) is devoid of moment of flexure. No tipping is produced between the injection nozzle (44) and the feed bush (43) of the injection-moulding tool.
