Abstract

The present invention relates to an arrangement of a two-step ejector (2) for a plastics-moulding machine (3) and comprises a piston-cylinder arrangement (4) with cylinder and piston elements (7, 8, 9) which are axially (5, 6) displaceable in relation to one another in various steps to influence separate movable ejector plates (10, 11). The piston element (9) is connected to a yoke-shaped attachment part (12), which for its part is connected to a front cylinder part (7). A number of radially (13, 14) displaceable segmental force-transferring pieces (15), which are permanently received in a matching relief (16) in the aforementioned front cylinder part (7) or a rear cylinder part (8), can also be alternately received in a matching annular groove (18, 19) in the piston (9) or in an outer bush (20). <IMAGE>
