Description
Die Erfindung betrifft eine Vorrichtung an einem Zweistufenauswerfer einer Kunstoff-Verformungsmaschine, umfassend eine Kolben-Zylindereinheit, die zum Verschieben separat beweglicher Auswerferplatten stufenweise verschiebbare Kolben-Zylinder-Elemente aufweist.The invention relates to a device on a two-stage ejector of a plastic deformation machine, comprising a piston-cylinder unit which has for moving separately movable ejector plates gradually displaceable piston-cylinder elements.
Eine solche Vorrichtung ist aus
Die bekannte Vorrichtung weist Nachteile auf. Sie ist aufwändig und teuer in der Herstellung und wenig bedienungsfreundlich. So ist die vordere Auswerferplatte mittels eines kurzen Bolzens befestigt. Dieser ist nur mit Hilfe eines langen Sechskantschlüssels zugänglich.The known device has disadvantages. It is complex and expensive to manufacture and not very easy to use. Thus, the front ejector plate is fastened by means of a short bolt. This is accessible only with the help of a long hex key.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der genannten Art zu verbessern. Sie soll einfacher im Aufbau, kostengünstiger in der Herstellung und leichter in der Bedienung sein.The invention has for its object to improve a device of the type mentioned. It should be simpler in construction, cheaper to manufacture and easier to use.
Diese Aufgabe wird durch die Merkmale von Anspruch 1 gelöst.This object is solved by the features of claim 1.
