Abstract
The arrangement is based on the principle that the ejector (9) of a moulding tool actuates the front ejector plates (4, 4A, 4B) and the rear plates (5, 5A, 5B) are conveyed along until the bearing segments reach the free groove in the central pin, which at the same time is provided with a stroke-restricting collar (20), in conjunction with which balancing against misalignment of the ejector package is obtained at the same time through the incorporation of this two-stage ejector, and, at the same time, that it replace extra guides.
