ABSTRACT:
The invention concerns an ejector system, where the ejectors or the stripper plates (10) in the turnable tool part(s) (8) are being activated in turn after each turning and opening/closing cycle in the machinery by means of a stationary placed mechanism (11). This can perform a forward and backwards movement, and is situated outside the turnable mold part(s), but in such a way that the stationary placed forward and backwards going mechanism (11) enables the shifting activations of the ejector mechanism (10) on the different sides of the turnable mold part(s) in turn. The stationary placed forward and backwards going mechanism (11) can perform its movements by hydraulic, pneumatic, electric or other influence of e.g. a piston. The turnable mold parts of the tool suitably turn around axis, which are parallel and at a right angle on the opening/closing movement of the tool. At a right angle at this axis is each turnable mold part preferably designed with a cross section, which makes up a regular polygon, preferably a square.
