Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Verformen einer erwärmten Platte oder eines Folienbahnabschnittes aus thermoplastischem Kunststoff zu einem Formteil nach der Gattung des Anspruches 1 bzw. des unabhängigen Anspruches 2.The The invention relates to a device for deforming a heated plate or a film web section made of thermoplastic material a molding according to the preamble of claim 1 and the independent claim Second
Die
Erfindung betrifft insbesondere den Antrieb des höhenbeweglichen
oberen Spannrahmens. Da die Schließ- und Öffnungsbewegung dieses Spannrahmens
in die Taktzeit eingeht wird eine möglichst kurze Zeit für diese
Bewegungen angestrebt, um die Taktzeit zum Herstellen eines Formteils
insgesamt kurz zu halten. Aus der

Der Erfindung liegt die Aufgabe zugrunde, die Vorrichtung so zu gestalten, dass ein rascher Bewegungsablauf mit sanftem Anlauf der Endlagen und hoher Schließkraft erfolgt. Der Aufwand für Gleichlaufeinrichtungen sollte gering, die Gefahr des Schiefhängens des Spannrahmens in oberer Lage durch Toleranzen und Verschleiß sollte nicht gegeben sein.Of the Invention has for its object to make the device so that a quick movement with gentle start of the end positions and high clamping force he follows. The effort for Synchronization facilities should be low, the risk of skewing of the Clamping frame should be in upper position due to tolerances and wear not be given.
Zur Lösung der Aufgabe werden die Merkmale des Anspruches 1 bzw. des unabhängigen Anspruches 2 vorgeschlagen. Vorteilhafte Weiterbildungen sind in den Unteransprüchen beschrieben.to solution The object of the features of claim 1 and the independent claim 2 proposed.
