Abstract
The invention relates to an arrangement for a two-stage ejector for an injection moulding tool. It comprises a piston cylinder arrangement with piston cylinder elements capable of axial displacement relative to one another in separate stages for the actuation of separately moving ejector plates, having the front plate attached to a piston capable of detachable attachment to a sleeve accommodating said piston via radially moving coupling segments. Internally inside the sleeve, which is attached to the rear plate via a threaded connection, an accommodating body for the coupling segments is fixed to the front plate via radial wings. The wings are capable of movement along the sleeve in matching recesses along the rear part of the sleeve.
