Abstract
(DE)
Die Erfindung betrifft ein Verfahren sowie eine Vorrichtung für das Schliessen der Formen (11, 12) bei einer Spritzgiessmaschine über einen Kniehebelmechanismus (5). Dabei wird vorgeschlagen, den ganzen Kniehebelmechanismus (5) mit einem Hydraulikzylinder (31) in der Maschine zwischen der Antriebsstützplatte (1) sowie der beweglichen Werkzeugaufspannplatte (2) anzuordnen. Der Hydraulikzylinder (31) ist über eine Kolbenstange (32) mit der Antriebsstützplatte (2) verbunden und greift an einem Kreuzkopf (20) des Kniehebemechanismus (5) zentral an.
(EN)
The invention relates to a method and a device for closing the moulds (11, 12) of an injection moulding machine by means of a crank mechanism (5). According to the invention, the complete crank mechanism (5) with a hydraulic cylinder (31) is arranged in the machine between the drive support plate (1) and the moving tool clamping plate (2). The hydraulic cylinder (31) is connected to the drive support plate (2) by means of a piston rod (32) and engages centrally with the crank mechanism at a cross-head (20).
(FR)
L'invention concerne un procédé et un dispositif permettant de fermer les moules (11, 12) d'une machine de moulage par injection par un mécanisme à levier à coudé (5). Selon l'invention, le mécanisme à levier coudé (5) en entier et un vérin hydraulique (31) sont placés dans la machine entre la plaque d'appui et d'entraînement (1) et le plateau porte-moule (2) mobile. Le vérin hydraulique (31) est relié à la plaque d'appui et d'entraînement (2) par une tige de piston (32) et entre en prise avec une crosse (20) du mécanisme à levier coudé (5).
