VERFAHREN ZUM BETRIEB EINER SPRITZGIESSMASCHINE

Die Holme einer Spritzgießmaschine werden mit Positionsmessern versehen, um die unterschiedliche Belastung der einzelnen Holme registrieren und auf einem Bildschirm darstellen zu können. A twin plate injection molding machine comprises a movable mould tensioning plate (2) and a fixed mould tensioning plate (1), and a number of tensioning rods over the plate edges, which supply the closure force. Each rod has a measurement unit which determines the rod position relative to a fixed tensioning plate. The measured position value for each rod is recorded, and the individual or averaged values can be displayed on a screen. The closure force can be reduced until the position value change is non-linear and shows maximum injection has been exceeded, after which the closure force is raised again. The movable plate is lifted by a cylinder unit (3). After mould closure, nuts (5) are tightened on the rods (11-14).
