Title
(DE) FORMNESTKAVITÄT MIT MÄANDERFÖRMIGEM KÜHLKANAL
(EN) MOULD CAVITY WITH DECOUPLED COOLING-CHANNEL ROUTING
(FR) CAVITÉ DE MOULE AVEC CANAL DE REFROIDISSEMENT EN FORME DE MÉANDRE
Abstract
(DE)
Die vorliegende Erfindung betrifft eine Kavität für ein Formnest zur Herstellung von Hohlkörperformlingen, wobei die Kavität (1) ein im wesentlichen hohlzylindrisches Element (2) aufweist, wobei an der Außenseite des hohlzylindrischen Elements (2) ein Kühlkanal vorgesehen ist. Um eine Kavität bereitzustellen, die einfach herzustellen ist und die eine effektivere Kühlung der Kavität ermöglicht, wird erfindungsgemäß vorgeschlagen, daß der Kühlkanal mehrere sich im wesentlichen in axialer Richtung erstreckende Kühlkanalabschnitte (3) und mindestens einen Kühlkanalverbindungsabschnitt (4) aufweist, wobei der Kühlkanalverbindungsabschnitt (4) zwei der sich im wesentlichen in axialer Richtung erstreckenden Kühlkanalabschnitte (3) verbindet.
(EN)
The present invention relates to a cavity for a mould-cavity system for the production of hollow mouldings, where the cavity (1) has an element (2) which is in essence hollow and cylindrical, where a cooling channel has been provided at the outer side of the hollow cylindrical element (2). 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 the cooling channel with a plurality of cooling-channel sections (3) extending substantially axially, and with at least one cooling-channel-connector section (4), where the cooling-channel-connector section (4) connects two of the cooling-channel sections (3) extending substantially axially.
(FR)
La présente invention concerne une cavité de moule pour créer des corps creux moulés. La cavité (1) présente un élément (2) sensiblement cylindrique creux et un canal de refroidissement est disposé sur le côté extérieur de l'élément cylindrique creux (2). Afin de produire une cavité qui soit facile à fabriquer et qui permette un refroidissement plus efficace de la cavité, le canal de refroidissement présente selon l'invention plusieurs sections de canal de refroidissement (3) s'étendant sensiblement dans la direction axiale et au moins une section de connexion de canal de refroidissement (4), la section de connexion de canal de refroidissement (4) reliant deux des sections de canal de refroidissement (3) s'étendant sensiblement dans la direction axiale.
