Abstract
(DE)
Die vorliegende Erfindung betrifft eine Kavität für ein Formnest zur Herstellung von Hohlkörper- formlingen, wobei die Kavität ein im wesentlichen hohlzylindrisches Element aufweist, wobei an der Außenseite des hohlzylindrischen Elements ein Kühlkanal vorgesehen ist. Um eine Kavität bereitzustellen, die einfach herzustellen ist und die eine effektivere Kühlung der Kavität ermöglicht, wird erfindungsgemäß vorgeschlagen, daß ein oder mehrere Führungselemente zur Bildung des Kühlkanals vorgesehen sind, wobei die Führungselemente und das hohlzylindrische Element als separate Teile ausgeführt sind.
(EN)
The present invention relates to a cavity for a mould-cavity system for the production of hollow mouldings, where the cavity has an element which is in essence hollow and cylindrical, where a cooling channel has been provided at the outer side of the hollow cylindrical element. To provide a cavity which is easy to produce and which can increase the effectiveness of cooling of the cavity, the invention proposes provision of one or more routing elements to form the cooling channel, where the routing elements and the hollow cylindrical element are separate parts.
(FR)
L'invention concerne une cavité pour un moule, pour la fabrication de corps creux moulés. La cavité présente un élément sensiblement cylindrique creux et un canal de refroidissement est disposé sur le côté extérieur de l'élément cylindrique creux. Afin de produire une cavité qui soit facile à fabriquer et qui permette un refroidissement plus efficace de la cavité, on utilise selon l'invention un ou plusieurs éléments de guidage pour former le canal de refroidissement, les éléments de guidage et l'élément cylindrique creux étant réalisés sous forme de pièces séparées.
