Abstract

Hydraulische Antriebseinheit (1) für eine Spritzgießmaschine, mit einem hydraulisch zwischen zwei Endpositionen (Et, E2) In einem Zylinder (2) bewegbaren Kolben zum Bewegen eines Spritzgießmaschinenteils, einer Hydraulikpumpe (4) zum Fördern von Hydraulikflüssigkeit, einer Hydraulikleitung (5) zwischen Hydraulikpumpe (4) und Zylinder (2) und einer Steuer- oder Regeleinheit (7) zum Steuern bzw. Regeln der Hydraulikpumpe (4), wobei von der Hydraulikpumpe (4) das Durchflussvolumen (Q) der Hydraulikflüssigkeit pro Zeiteinheit (t) messbar ist und ein entsprechendes Signal der Steuer- oder Regeleinheit (7) weiterleitbar ist, welche daraus die Position (P) des Kolbens berechnet.
