Abstract
The arrangement is based on the principle that the ejector (9) of a moulding tool actuates the rear ejector plates (5, 5A, 5B) and the front plates (4, 4A, 4A) are conveyed along until the bearing segments (23) reach the free groove (17) in central pin (12). 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, it replaces extra guides.
