The present invention relates to an arrangement (1) for a two-stage ejector (2) for injection moulding tools (6) and similar moulding tools. It comprises a pin-shaped first ejection part (3), which is so arranged as to be actuated directly for the purposes of ejection and to act on the ejector plate (4) that is so arranged as to be displaced in a first and a second ejector stage (I, II), and a sleeve-shaped second ejection part (5), which is so arranged as to act on the ejector plate (8) that is so arranged as to be displaced only in the aforementioned first ejector stage (I). It also comprises coupling devices (7) for the detachable attachment of the two aforementioned ejector parts (3, 5) with one another. The first ejecting part (3) is attached to the upper plate (4) of the two ejector plates (4, 8) by means of an inlaid hook bolt (13) provided with threads (14) which have a fine pitch and capable of accommodation in a threaded central hole (16) in the first ejecting part (3). The second ejecting part (5) is connected to the bottom plate (8) by means of a screwed attachment body (18), which is so arranged as to enclose the aforementioned sleeve-shaped second ejecting part (5) with a clearance. <IMAGE> |
