Description

Die vorliegende Erfindung betrifft eine Gießkammer für das Druckgießen von Metallen mit einem Gießkammermantel und Heizmitteln zur Vorwärmung der Gießkammer.The present invention relates to a casting chamber for die casting of metals with a casting chamber jacket and heating means for preheating the casting chamber.

Gießkammern der vorstehend genannten Art sind beispielsweise aus der WO99/5007 bekannt und werden in erster Linie in Druckgießmaschinen zum Druckgießen von Metallen wie beispielsweise Aluminium, Magnesium und Messing eingesetzt. Dabei werden hauptsächlich horizontale Gießkammern verwendet, die an ihrem einen, maschinenseitigen Ende obenseitig eine Gußmaterialeinfüllöffnung und an ihrem anderen, formseitigen Ende eine Gußmaterialauslaßöffnung aufweisen.Casting chambers of the type mentioned above are for example known from WO99 / 5007 and are primarily in die casting machines for die casting of metals such as aluminum, magnesium and brass. Mainly horizontal casting chambers used that at their one, machine-side end a cast material filler opening on the top and on her the other, mold-side end a casting material outlet opening exhibit.

Den Gießkammern wird das Gußmaterial in flüssiger, zum Teil aber auch in halbfester Form zugeführt. Gerade im letzteren Fall tritt das Problem auf, daß sich das Gußmaterial beim Einfüllen in die Gießkammer ungleichmäßig abkühlt, was sich negativ auf die Qualität des fertigen Gußteils auswirken kann. Aus diesem Grund sind bei der bekannten Gießkammer Heizelemente in Form von Heizringen um die Gießkammer herum vorgesehen, um die Gießkammer je nach verwendetem Metall auf eine Temperatur zwischen 550 und 600°C vorzuwärmen und auf diese Weise das Material in einem halbverfestigten Zustand zu halten.The casting chamber is the casting material in liquid, for Part but also supplied in semi-solid form. Especially in the latter case, the problem arises that the molding material cools unevenly when poured into the casting chamber, which negatively affects the quality of the finished Cast part can affect. For this reason, the known casting chamber heating elements in the form of heating rings provided around the casting chamber, depending on the casting chamber after the metal used to a temperature between 550 and preheat 600 ° C and in this way the material in maintain a semi-solidified state.

Durch die Erwärmung der Gießkammer können zwar unerwünschte Verfestigungen des Gießmaterials verhindert werden. Der gerätetechnische Aufwand ist aufgrund der Vielzahl von benötigten Heizelementen jedoch hoch. Außerdem ist auch die erforderliche Heizleistung immens.The heating of the casting chamber can cause unwanted Solidification of the casting material can be prevented. The expenditure on equipment is due to the large number of heating elements required, however, high. Moreover the heating power required is also immense.

Aufgabe der Erfindung ist es daher, eine Gießkammer der eingangs genannten Art so auszubilden, daß eine gleichmäßige Erwärmung der Gießkammer mit vergleichsweise geringem Aufwand möglich ist.The object of the invention is therefore a casting chamber trained in such a way that a uniform Heating the casting chamber with comparatively little Effort is possible.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß als Heizmittel mehrere Heizstäbe entlang des Umfangs der Gießkammer verteilt angeordnet sind, welche in den Gießkammermantel von seiner einen Stirnseite her eingesetzt sind und sich in Längsrichtung der Gießkammer erstrecken.This object is achieved in that as Heating means several heating rods along the circumference of the Casting chamber are arranged distributed, which in the casting chamber jacket inserted from one end are and extend in the longitudinal direction of the casting chamber.

Mittels der Heizstäbe, die sich in dem Gießkammermantel erstrecken, läßt sich die Gießkammer sehr gleichmäßig über ihre axiale Länge vorwärmen. Da solche Heizstäbe im Handel frei erhältlich sind, ist der gerätetechnische Aufwand vergleichsweise gering. Des weiteren kann eine schnelle Aufheizung erfolgen, da der Gießkammermantel von innen her erwärmt wird und nicht wie im Stand der Technik durch äußere Manschetten oder Heizringe.By means of the heating rods, which are in the casting chamber jacket extend, the casting chamber can be very even Preheat along its axial length. Since such heating elements in Trade is freely available, the device is technical Comparatively little effort. Furthermore, one rapid heating takes place because the casting chamber jacket from is heated inside and not as in the prior art through outer cuffs or heating rings.

Gemäß einer bevorzugten Ausführungsform ist vorgesehen, daß die Heizstäbe einzeln oder gruppenweise ansteuerbar sind, um die Heizleistung einzustellen. Diese Ausführungsform trägt dem Umstand Rechnung, daß das in die Gießkammer eingefüllte Material sich nicht gleichmäßig abkühlt, sondern beispielsweise im Bereich der Einfüllöffnung, wo es in direktem Kontakt mit der Luft steht, stärker abkühlt als in den übrigen Bereichen. Dadurch, daß die Heizstäbe unabhängig voneinander angesteuert werden können, kann eine bedarfsgerechte Heizleistung zur Verfügung gestellt werden mit der Folge, daß das Gießmaterial über den Umfang der Gießkammer eine gleichmäßige Temperatur behält.According to a preferred embodiment, that the heating elements can be controlled individually or in groups to set the heating output. This embodiment takes into account the fact that the Pouring material poured out not evenly cools, but for example in the area of the filling opening, where it is in direct contact with the air, cools more than in the other areas. Thereby, that the heating elements are controlled independently of each other can, a needs-based heating output for Be made available with the result that the casting material uniform over the circumference of the casting chamber Temperature retains.

Die Steuerung der Heizstäbe kann über einen Regelkreis erfolgen, wobei zweckmäßigerweise Temperaturfühler vorgesehen sind, um die Temperatur der Gießkammer an der Oberfläche der Kolbenbohrung an mehreren Meßpunkten entlang des Gießkammerumfangs zu ermitteln. Der Regelkreis kann dann die Leistung der Heizstäbe in Abhängigkeit von den gemessenen Temperaturen so regeln, daß sich an der Innenseite der Gießkammer eine Temperatur von 560°C bis 620°C, und bei der Verwendung von Aluminium als Gießmaterial insbesondere von 570°C bis 580°C einstellt.The heating elements can be controlled via a control loop take place, expediently provided temperature sensors are the temperature of the casting chamber on the surface the piston bore along several measuring points of the circumference of the casting chamber. The control loop can then the performance of the heating rods depending on the regulate the measured temperatures so that there is no the casting chamber has a temperature of 560 ° C to 620 ° C, and when using aluminum as a casting material especially from 570 ° C to 580 ° C.

Gemäß einer weiteren Ausführungsform der Erfindung ist vorgesehen, daß sich die elektrischen Heizstäbe im wesentlichen über die gesamte axiale Länge der Gießkammer erstrecken. Auf diese Weise kann mit Ausnahme der axialen Endbereiche eine konstante Temperatur des Gießmaterials über die Länge der Gießkammer erzielt werden.According to a further embodiment of the invention provided that the electric heating elements essentially over the entire axial length of the casting chamber extend. This way, with the exception of the axial End areas a constant temperature of the casting material can be achieved over the length of the casting chamber.

In alternativer Weise kann vorgesehen sein, daß die Gießkammer axial unterteilt ist in ein Heizteil mit einer Einlegeöffnung zum Einbringen des Gießmaterials und ein Druckteil, in welchem eine Druckform vorgesehen ist und in welches das Gießmaterial aus dem Heizteil durch einen axial in das Heizteil eingreifenden Kolben hineingedrückt werden kann, wobei die Heizstäbe nur in dem Heizteil vorgesehen sind und sich im wesentlichen über dessen ganze axiale Länge erstrecken. Dabei kann das Heizteil von einem Wärmeisolationsmantel umgeben sein, welcher die Wärmeabgabe an die Umgebung verringert.Alternatively, it can be provided that the casting chamber is divided axially into a heating part with a Insertion opening for inserting the casting material and an Printing part in which a printing form is provided and in which the casting material from the heating part through a axially engaging piston engaging in the heating part can be provided, the heating rods only in the heating part and are essentially all of it extend axial length. The heating unit can be from one Thermal insulation jacket to be surrounded, which the heat emission reduced to the environment.
