Title (EN) SUPPLY DEVICE FOR SUPPLYING PASTY MASSES
(FR) DISPOSITIF D'AMENÉE POUR L'AMENÉE DE SUBSTANCES PÂTEUSES
(DE) ZUFÜHRUNGSVORRICHTUNG ZUM ZUFÜHREN VON PASTÖSEN MASSEN
Abstract:
(EN) The invention relates to a supply device for supplying pasty masses, in particular silicone, to an injection molding machine, comprising a pressing cylinder, which holds the pasty mass, and a pressing piston, which is axially arranged in said pressing cylinder and presses the pasty mass out of a press-out nozzle of the pressing cylinder. The problem addressed by the invention is that of avoiding operation interruptions for cleaning work and avoiding material losses within the supply device when different pasty masses are used in succession, in the case of such a supply device. In order to solve this problem, according to the invention, the pressing cylinder is designed as a cartridge (3) containing the pasty mass, which cartridge consists of a polymer and can be exchangeably inserted into a support housing (2), which supports the cartridge on all sides and is connected to an axial actuating drive (5) for the pressing piston (3d) located in the cartridge.
(FR) L'invention concerne un dispositif d'amenée pour l'amenée de substances pâteuses, en particulier de silicone, à une machine de moulage par injection. Le dispositif comprend un vérin principal de filage recevant la substance pâteuse et un piston presseur qui est agencé axialement dans ce vérin principal de filage et qui fait sortir la substance pâteuse d'une buse d'exprimage du vérin principal de filage en la pressant. L'objet de l'invention est d'éviter, avec ledit dispositif d'amenée, des interruptions de fonctionnement pour des opérations de nettoyage, et, lorsque différentes substances pâteuses sont utilisées successivement, des pertes de matériau à l'intérieur du dispositif d'amenée. À cet effet, selon l'invention, le vérin principal de filage est réalisé sous la forme d'une cartouche (3) contenant la substance pâteuse, laquelle cartouche est constituée d'un polymère et peut être insérée de manière interchangeable dans un boîtier support (2), lequel soutient la cartouche de tous côtés et est relié à un mécanisme de commande axial (5) pour le piston de presse (3d) situé dans la cartouche.
(DE) Die Erfindung betrifft eine Zuführungsvorrichtung zum Zuführen von pastösen Massen, insbesondere von Silikon, zu einer Spritzgießmaschine, mit einem die pastöse Masse aufnehmenden Presszylinder und einem axial in diesem Presszylinder angeordneten Presskolben, der die pastöse Masse aus einer Auspressdüse des Presszylinders herauspresst. Es ist Aufgabe der Erfindung, bei einer solchen Zuführungsvorrichtung Betriebsunterbrechungen für Reinigungsarbeiten zu vermeiden und bei aufeinanderfolgender Verwendung unterschiedlicher pastöser Massen Materialverluste innerhalb der Zuführungsvorrichtung zu vermeiden. Zur Lösung dieser Aufgabe schlägt die Erfindung vor, dass der Presszylinder als die pastöse Masse enthaltende Kartusche (3) ausgebildet ist, die aus einem Polymer besteht und auswechselbar in ein Stützgehäuse (2) einsetzbar ist, welches die Kartusche allseitig abstützt und mit einem axialen Stellantrieb (5) für den in der Kartusche befindlichen Presskolben (3d) verbunden ist.
