Description

Massezylinder für Spritzmaschinen für plastische Massen Die Erfindung betrifft eine Verbesserung und weitere Ausbildung des Gegenstandes von Patent 6o6603.Mass cylinder for injection molding machines for plastic masses The invention relates to an improvement and further development of the subject matter of patent 6o6603.

Das Patent bezieht sich auf einen Massezylinder für Spritzmaschinen für plastische Massren, dessen Querschnitt. durch Heizrippen von gut wärmeleitendem Material unterteilt ist, denen die Wärme von außen durch Wärmeleitung zugeführt wird. Die dargestellte Ausführungsform zeigt einen Rippenkörper, bei dem radial verlaufende Rippen von einem zentralen Körper ausgehen und mit der inneren Wandung des Massezylinders in wärmeleitender Berührung stehen.The patent relates to a barrel for injection molding machines for plastic mass, its cross-section. by heating ribs of good heat conducting Material is subdivided to which the heat is supplied from the outside through thermal conduction will. The illustrated embodiment shows a rib body in which radially running ribs start from a central body and with the inner wall of the mass cylinder are in thermally conductive contact.

Die weitere Ausbildung gemäß der Erfindung besteht darin, daß der zentrale Einsatzkörper in Fortfall kommt, indem die radialen Heizrippen zwar von der inneren Wandung des Massezylinders ausgehen, aber nicht in der Mitte des Massezylinders zusammengeführt sind, sondern dort einen freien Raum lassen. Diese Ausführung bietet unter bestimmten Verhältnissen einen geringeren Widerstand für die durch den Massezylinder hindurchgepreßte Masse als die ältere Ausführungsform, indem der mittlere Kernkörper überhaupt in Fortfall kommt und die radialen Heizrippen so ausgebildet sein können, daß in Richtung des bewegten Materials von ihrem Beginn an ein sanftes Ansteigen stattfindet, wodurch scharfe Winkel, die bei einem zentralen Einsatzkörper gemäß der älteren Ausführung vorhanden sind, vermieden werden.The further training according to the invention is that the central insert body in omission comes by the radial heating ribs from the inner wall of the mass cylinder, but not in the middle of the mass cylinder are brought together, but leave a free space there. This version offers under certain conditions a lower resistance for the mass cylinder pressed through mass than the older embodiment, by the middle core body no longer exists and the radial heating ribs can be designed in such a way that that in the direction of the material being moved a gentle rise from its beginning takes place, whereby sharp angles, which according to a central insert body the older version should be avoided.

Auf der Zeichnung ist ein Ausführungsbeispiel der Vorrichtung dargestellt.An exemplary embodiment of the device is shown in the drawing.

Fig. I zeigt ;einen Längsschnitt durch den Massezylinder und die Verbindung der Rippen mit dem äußeren Mantel, wobei der zentrale Körper in Fortfall gekommen ist.Fig. I shows a longitudinal section through the mass cylinder and the connection of the ribs with the outer mantle, with the central body ceased to exist is.

Fig. z zeigt einen Querschnitt.Fig. Z shows a cross section.

Der Massezylinder ist mit a bezeichnet und die von der Wandung des Massezy linders ausgehenden Rippen mit d. Bei dem dargestellten Ausführungsbeispiel sind die Rippen mit dem Zylinder aus einem Stück gegossen, was aber nicht unbedingt nötig ist.The mass cylinder is denoted by a and that of the wall of the Massezy Linders outgoing ribs with d. In the illustrated embodiment the ribs are cast in one piece with the cylinder, but this is not necessarily the case is necessary.
