Abstract

An electrically heated injection nozzle for pressure die casting machines has bores to receive the heating cartridges which are directly arranged in the nozzle. One or several cartridges lie parallel to the centre line of the nozzle and extend as far to the injection opening as possible. One or more additional heating cartridges are accommodated at right angles to the centre line. This saves space compared with extraneous heating cartridges and results in a more efficient heating of the nozzle point.

Description

Bezeichnung: @iektrisch beheizbare Einspri@zdüseDesignation: electrically heated injection nozzle

f@. Warmkammer-Druckgießmaschinen Es sind Ausführungen für elektrisch beheizte Einspritzdüsen bekannt, die mit einer Heizmantel versehen sind, der seinerseits als Aufnah@e f@@ elektrische Heizpatronen, Heizwendel oder dergleichen dient. f @. Hot chamber die casting machines There are versions for electric heated injection nozzles known, which are provided with a heating jacket, which in turn serves as a receptacle for electrical heating cartridges, heating coils or the like.

DEr Erfindung liegt je Aufgabe zu Grunde, die Ummantelung als zusätzliches Bauteil einerseies und den vornehmlich be kleineren Maschinen störenden Platzbedarf für @@e Ummantelung andererseits einzusparen und zudem eine möglichst unmittelbare Beheizung der Problempartien, z.B. der Düsenspitze, zu erreichen.The invention is based on each task, the sheathing as an additional One component and the space requirements, which are particularly disruptive in smaller machines on the other hand to save for @@ e sheathing and also as immediate as possible To achieve heating of the problem areas, e.g. the nozzle tip.

Erfindungsgemäß ist diese Aufgabe d'durch gelöst, daß die Aufnahmebohrungen für Heizpatronen direkt in der Düse angeordnet sind; in einer bevorzugten Ausführung so, daß eine oder mehrere Patronen (1) annähernd narallel zur Düsen-Längsachse möglichst weit zur Düsenspitze hin aufgenomrnen sind um die Abschmelztemperatur im Düsenspitzenbereich zu erzeugen, Während eine oder mehrere weitere Patronen (2) @uer zur Düsen-Längsachse aufgenommen sind. Diese Anordnung ermöglicht einfache Montage der einzelnen Heizpatronen, wobei die Düse in eingebautem Zustand verbleiben kann.According to the invention, this object is achieved by the fact that the receiving bores for heating cartridges are arranged directly in the nozzle; in a preferred embodiment so that one or more cartridges (1) as close as possible to the longitudinal axis of the nozzle far towards the nozzle tip are recorded around the melting temperature in the nozzle tip area to produce, While one or more further cartridges (2) @uer to the nozzle longitudinal axis are included. This arrangement enables simple assembly of the individual heating cartridges, whereby the nozzle can remain in the installed state.

Claims (2)

Schutzansprüche 1) Elektrisch beheizbare Einspritzdüse für Warmkammer-Druckgießmaschinen, dadurch gekennzeichnet, daß aufnahmebohrunden für Herzpatronen direckt in der Düse angeordner sind.Protection claims 1) Electrically heatable injection nozzle for hot chamber die casting machines, characterized in that receiving bores for heart cartridges directly in the nozzle are arranged. 2) Einspritzdüse nach Anspruch 1) dadurch gekennzeichnet, daß eine oder mehrere Aufnahmebohrungen annähernd parallel zur Düsen-Längsachse möglichst weit zur Düsenspitze hin angeordnet sind, und daß eine oder mehrere weitere Bohrungen quer zur Düser-Längsachse eingebracht sind.2) Injection nozzle according to claim 1), characterized in that one or several mounting holes approximately parallel to the longitudinal axis of the nozzle, if possible are arranged far towards the nozzle tip, and that one or more further bores are introduced transversely to the longitudinal axis of the nozzle.
