The invention relates to an ejector coupling for moulds for plastics processing, the ejector of which is actuated by a hydraulic cylinder on the machine side. In order to permit rapid coupling of the ejector and to compensate for parallel and inclined deviations from alignment between machine and mould, the ejector coupling is characterised by a ball-head pin (1) which is mounted so as to be pivotable in all directions in a ball-head socket (2, 3), by a union ring (5) screwed to the ball-head socket (2, 3), which union ring engages with an adjustment thread part (8a) and with key faces (8b) via a coupling sleeve (4) to receive a mould-side coupling pin (8) in such a manner that the coupling sleeve (4) on the ball-head socket (2, 3) is held in the axial direction, but movable in the radial direction, by an adjustment nut (6) which can be screwed onto a thread part (5a) of the coupling sleeve (4) and has a locking ring (7), which is held in the adjustment nut (6) in the axial direction but is movable in the radial direction, by catch elements (4a) disposed in the wall of the coupling sleeve (4) which are displaced radially inwards by the locking ring (7) by screwing down the adjustment nut (6) onto the union ring (5) and thus engage in a locking manner in a groove (8c) of the coupling pin (8) inserted into the coupling sleeve (4) and the ...
