Abstract

A two-stage ejector (2) in a molding tool (3), comprising an actuator part (7) exhibiting connecting segments (5) capable of radial displacement (4) and an attaching part (6) capable of detachable attachment to the actuator part (7). The attaching part is a telescopic tube (8) for determining the length of stroke attached to the inside (50A) of a front part (50) of the tool. The connecting tube (8) exhibits pairs of slots (10, 11) along its length. An attachment part (13) capable of being attached to a moving from ejector plate (12) is accommodated in the slots (10, 11) and is capable of displacement in the longitudinal extent (A) of the slots. A moving rear ejector plate (9) is attached to the actuating part (7), and the actuating part (7) is capable of displacement in a hole (17) passing through the tool frame (16), in the interior of which the rear part (18) of the actuating part is accommodated within the side (19) of the frame (16) facing away from the ejector plates.
