Injection machine for molding components has two moving platens and fixed central platen comprising a fixed part and a rotatable part which can also be locked in a fixed position

摘要

Two independent injection units are mounted on movable tool supporting platens(1,2) on at least one machine base(8). Both tool supporting platens move to and from a rotatable central platen(3) comprising a fixed part(4) connected to the machine base and rotatable part(5). The rotatable part can be fixed in position relative to the machine base. Clamping members provide positive connection between the rotating part(5) of the central platen(3) and the machine base(8). Release of the positive connection is performed by the machine control unit. A gap is created between the rotating part and the machine base either by raising the rotating part or introducing and intermediate layer. The axial position of the central platen is fixed on the machine base. An independent claim is included for a method for rotating part(5) of the central platen(3) on the claimed machine in which, prior to rotation, a positive connection between the rotatable part and the machine base(8) is released.
