(FR) DISPOSITIF À CANAL CHAUD OU FROID POUR UN OUTIL DE MOULAGE PAR INJECTION DOTÉ D'UN INSERT DE DÉVIATION ET D'UN INSERT DE DISTRIBUTION INTERCHANGEABLES
Abstract
(DE)
Eine Heiß- oder Kaltkanalvorrichtung für ein Spritzgießwerkzeug, mit einem Verteilerblock (3) für Polymerschmelzen oder polymere Flüssigkeiten, wie flüssiges Silikon, wobei der Verteilerblock (3) mindestens eine zentrale Zuleitung, mindestens einen Schmelzekanal, mindestens einen Fluidauslass sowie wenigstens einen wechselbaren Umlenk- und/oder Verteileinsatz (28) aufweist, wobei das der Umlenk- und/oder Verteileinsatz (28) eine Hülse (2) und ein Konuselement (1) zum Umlenken und/oder Verteilen der Schmelzen oder Flüssigkeiten aufweist und dass er spaltfrei und versatzfrei bzw. ohne Versatz an Strömungskanalübergängen (25) mittels eines Einpressvorgangs montiert ist und das Konuselement (1) selbsthemmend in der Hülse (2) gehalten ist.
(EN)
The invention relates to a hot or cold runner device for an injection mould, said device comprising a distributor block (3) for polymer melts or polymeric liquids such as liquid silicone, wherein the distributor block (3) comprises at least one central supply line, at least one melt channel, at least one fluid outlet, and at least one exchangeable deflection and/or distribution insert (28), wherein the deflection and/or distribution insert (28) has a sleeve (2) and a cone element (1) for deflecting and/or distributing the melts or liquids and is mounted without gaps and without offset at flow channel transitions (25) by means of a pressing-in process, and the cone element (1) is held in the sleeve (2) in a self-locking manner.
(FR)
La présente invention concerne un dispositif à canal chaud ou froid pour un outil de moulage par injection, doté d'un bloc de distribution (3) pour des masses fondues de polymère ou des liquides polymériques, comme une silicone liquide, le bloc de distribution (3) présentant au moins une conduite centrale, au moins un canal pour masse fondue, au moins une sortie de fluide ainsi qu'au moins un insert de déviation et/ou un insert de distribution (28) interchangeables, l'insert de déviation et/ou l'insert de distribution (28) présentant une enveloppe (2) et un élément de cône (1) pour la déviation et/ou la distribution de masses fondues ou de liquide et étant monté au moyen d'une opération d'étalonnage sans interstice et sans décalage respectivement sans décalage au niveau de jonctions de canaux d'écoulement (25) et l'élément de cône (1) étant maintenu de manière autobloquante dans l'enveloppe (2).
