Beschreibung
Zusammenfassung:	The control device has a stop element moved by a drive unit. The stop element strikes another stop element in a course of an injection molding process. A detection device (11) is provided for measuring force with which the former stop element strikes the latter stop element. The force is measured and supplied over a transmission device of the control device. The force is compared with a reference value. A brake device is controlled for delaying of the former stop element and/or a drive element (2) staying in effective connection with the former stop element. An independent claim is also included for an injection molding machine comprising a control device and an ejector pin. hine (34) mit einem von einer Antriebseinheit (2) bewegten ersten Anschlagelement (2'), wobei das erste Anschlagelement (35) im Zuge des Spritzgießprozesses auf ein zweites Anschlagelement (36) aufprallt, wobei eine Detektionsvorrichtung (11) vorgesehen ist, von der die Kraft, mit der das erste Anschlagelement (35) auf das zweite Anschlagelement (36) aufprallt, messbar und über eine Übertragungsvorrichtung (33) der Steuerungsvorrichtung (31) zuführbar ist.
