A clamping assembly for an injection moulding installation.

摘要

A clamping assembly for an injection moulding installation, characterised in that it comprises: a rigid elongated base frame (51); a fixed platen (52) mounted with respect to said base frame so that there is inhibited displacement in a longitudinal axial direction of the base frame of the fixed platen with respect to the base frame; a movable platen (53); longitudinal sliding bearings (55,56) fixed with respect to said base frame (51) and on which said movable platen (53) is mounted, said bearings being positioned substantially outside the effective clamping region between said platens; and platen drive means (60,61) rigidly mounted with respect to said base frame (51) and coupled to said movable platen (53) for transmitting thereto an axially directed displacement; the arrangement being such that said clamping region is substantially free of any bending induced in said base frame and arising from clamping forces. <IMAGE>
