Description

Die vorliegende Erfindung betrifft eine Gießkammer einer Druckgießmaschine mit einem innerhalb der Gießkammer beweglichen Gießkolben und mindestens einem Ablauf zum Ablauf des flüssigen metallischen Druckgießmaterials in mindestens einen Gießlauf, wobei der Gießlauf mit einem Formhohlraum in Verbindung steht. Des Weiteren betrifft die Erfindung ein Verfahren zur Formfüllung einer Druckgießmaschine.The present invention relates to a casting chamber of a die casting machine with a casting piston movable within the casting chamber and at least one outlet for the discharge of the liquid metallic die casting material into at least one casting barrel, the casting barrel being connected to a mold cavity. Furthermore, the invention relates to a method for filling the mold of a die casting machine.

Derartige Gießkammern für Druckgießmaschinen und Verfahren zur Formfüllung einer Druckgießmaschine sind bekannt. Üblicherweise wird bei horizontalen Kaltkammerdruckgießmaschinen das flüssige Metall über einen geeigneten Kanal, nämlich dem Gießlauf im sogenannten Gießamboss, der in ein formenseitiges Ende der Gießkammer eintaucht, in einen sogenannten Anschnitt und anschließend in den Formhohlraum geführt. Der Verbindungskanal zwischen der Gießkammer und dem Gießlauf ist üblicherweise derart angeordnet, dass das flüssige Metall erst bei einem sehr hohen Füllgrad der Gießkammer in den Gießlauf gelangt. Nachteiligerweise entstehen verfahrensbedingt bei der Befüllung der Gießkammer mit flüssigem Metall durch dessen Affinität mit Sauerstoff Oxide, die sich auf der Metalloberfläche beziehungsweise Badoberfläche ansammeln. Durch die relativ hohe Anordnung des Verbindungskanals zum Gießlauf im Gießamboss gelangt der auf der Badoberfläche der Gießkammer stark oxidhaltige Anteil der Schmelze während der Formfüllung direkt in den Formhohlraum des zu gießenden Gussteils. Im resultierenden Gussteil treten die Oxide in der Regel als flächenförmige Störungen im Gefüge auf und beeinflussen nachteiligerweise die mechanischen Eigenschaften der Gussteile.Casting chambers of this type for die casting machines and methods for filling molds in a die casting machine are known. In horizontal cold chamber die casting machines, the liquid metal is usually passed through a suitable channel, namely the casting run in the so-called casting anvil, which dips into a mold-side end of the casting chamber, into a so-called gate and then into the mold cavity. The connecting channel between the casting chamber and the casting run is usually arranged such that the liquid metal only reaches the casting run when the casting chamber is very full. Disadvantageously, process-related, when the casting chamber is filled with liquid metal due to its affinity with oxygen, oxides are formed which collect on the metal surface or bath surface. Due to the relatively high arrangement of the connecting channel to the casting run in the casting anvil, it reaches the bath surface the casting chamber contains a high proportion of oxide in the melt during mold filling directly into the mold cavity of the casting to be cast. In the resulting cast part, the oxides generally appear as sheet-like defects in the structure and adversely affect the mechanical properties of the cast parts.

Es ist daher Aufgabe der vorliegenden Erfindung eine Gießkammer einer Druckgießmaschine der eingangs genannten Art bereitzustellen, die einen Eintritt von oxidhaltigen Anteilen des Gießmaterials in einen Formhohlraum zuverlässig verhindert.It is therefore an object of the present invention to provide a casting chamber of a die casting machine of the type mentioned at the outset, which reliably prevents oxide-containing parts of the casting material from entering a mold cavity.

Es ist weiterhin Aufgabe der vorliegenden Erfindung ein Verfahren zur Formfüllung einer Druckgießmaschine bereitzustellen, welches einen Eintritt von oxidhaltigen Anteilen des Gießmaterials in einen Formhohlraum zuverlässig verhindert.It is a further object of the present invention to provide a method for mold filling a die casting machine, which reliably prevents oxide-containing parts of the casting material from entering a mold cavity.

Zur Lösung dieser Aufgaben dient eine gattungsgemäße Gießkammer gemäß den Merkmalen des Hauptanspruchs 1 und ein Verfahren gemäß den Merkmalen des unabhängigen Anspruchs 5.A generic casting chamber according to the features of main claim 1 and a method according to the features of independent claim 5 are used to solve these tasks.

Vorteilhafte Ausgestaltungen sind in den jeweiligen Unteransprüchen beschrieben.Advantageous configurations are described in the respective subclaims.

Eine erfindungsgemäße Gießkammer einer Druckgießmaschine mit einem innerhalb der Gießkammer beweglich angeordneten Gießkolben und mindestens einem Ablauf zum Ablaufen des flüssigen metallischen Druckgießmaterials in mindestens einen Gießlauf, wobei der Gießlauf mit einem Formhohlraum in Verbindung steht, weist vorteilhafterweise einen Ablauf auf, der formseitig im Bereich des Bodens der Gießkammer angeordnet ist. Somit wird die Metallzufuhr in den Gießlauf zum Anschnitt des Gussteils am unteren formseitigen Austritt der Schmelze aus der Gießkammer in die Form eingebracht. Dadurch wird vorteilhafterweise erreicht, dass während der Vorwärtsbewegung des Gießkolbens eine Separierung der oxidbehafteten leichteren, und damit oberen Metallschicht nicht in den Bereich des Bodens der Gießkammer angeordneten Ablauf kommt. Nur oxidarmes beziehungsweise oxidfreies Gießmaterial strömt aus dem unteren Bereich der Gießkammer in den Gießlauf und damit in den Formhohlraum. Somit wird der Eintritt von oxidhaltigen Anteilen des Gießmaterials in den Formhohlraum zuverlässig verhindert.A casting chamber of a die casting machine according to the invention with a casting piston movably arranged within the casting chamber and at least one outlet for draining the liquid metallic die casting material into at least one casting barrel, the casting barrel being connected to a mold cavity, advantageously has a drain which is in the region of the bottom on the mold side the casting chamber is arranged. The metal feed is thus introduced into the casting run to cut the cast part at the lower mold-side outlet of the melt from the casting chamber into the mold. It is thereby advantageously achieved that during the forward movement of the casting piston, a separation of the lighter, and therefore upper, metal layer, which contains oxide, does not come into the region of the bottom of the casting chamber. Only low-oxide or oxide-free casting material flows from the lower area of the casting chamber into the casting run and thus into the mold cavity. Consequently the entry of oxide-containing parts of the casting material into the mold cavity is reliably prevented.

In einer vorteilhaften Ausgestaltung der Erfindung ist im oberen, dem Bodenbereich gegenüberliegenden Bereich der Gießkammer formseitig mindestens ein Überlaufkanal, der in mindestens einen Überlaufbehälter mündet, ausgebildet. Durch die zusätzliche Anordnung eines oberen formseitigen Austritts der Schmelze aus der Gießkammer erfolgt eine Separierung der oxidhaltigen Anteile über den Überlaufkanal in den Überlaufbehälter und ein Fließen des oxidarmen beziehungsweise oxidfreien Gießmaterials aus dem unteren Bereich der Gießkammer in den Formhohlraum. Durch die Abschöpfung der oxidhaltigen Anteile des Gießmaterials und deren Überführung in den Überlaufbehälter wird wiederum der Eintritt von oxidhaltigen Anteilen des Gießmaterials in den Formhohlraum zuverlässig verhindert.In an advantageous embodiment of the invention, at least one overflow channel, which opens into at least one overflow container, is formed in the upper region of the casting chamber opposite the base region. Due to the additional arrangement of an upper mold-side outlet of the melt from the casting chamber, the oxide-containing components are separated via the overflow channel into the overflow container and the low-oxide or oxide-free casting material flows from the lower region of the casting chamber into the mold cavity. By skimming off the oxide-containing parts of the casting material and transferring them to the overflow container, the entry of oxide-containing parts of the casting material into the mold cavity is in turn reliably prevented.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist das Gießmaterial eine Schmelze eines Leichtmetalls oder einer Leichtmetall-Legierung, wobei das Leichtmetall insbesondere Aluminium oder Magnesium ist.In a further advantageous embodiment of the invention, the casting material is a melt of a light metal or a light metal alloy, the light metal being in particular aluminum or magnesium.

Ein erfindungsgemäßes Verfahren zur Formfüllung einer Druckgießmaschine umfasst folgende Schritte: (a) Einfüllen eines flüssigen metallischen Druckgießmaterials in eine Gießkammer und (b) Bewegen eines innerhalb der Gießkammer angeordneten Gießkolbens in Richtung eines Formhohlraums und Überführung des Gießmaterials über mindestens einen Ablauf in mindestens einen Gießlauf, wobei der Gießlauf mit dem Formhohlraum in Verbindung steht und der Ablauf formseitig im Bereich des Bodens der Gießkammer angeordnet ist. Durch die Zufuhr des Gießmaterials in den Gießlauf zum Anschnitt des Gussteils am unteren formseitigen Austritt des Gießmaterials aus der Gießkammer wird zuverlässig der Eintritt von oxidhaltigen Anteilen des Gießmaterials in den Formhohlraum verhindert.A method according to the invention for mold filling a die casting machine comprises the following steps: (a) filling a liquid metallic die casting material into a casting chamber and (b) moving a casting piston arranged within the casting chamber in the direction of a mold cavity and transferring the casting material via at least one outlet into at least one casting run, wherein the pouring run is connected to the mold cavity and the outlet on the mold side is arranged in the region of the bottom of the casting chamber. By feeding the casting material into the casting run to cut the casting at the lower mold-side outlet of the casting material from the casting chamber, the entry of oxide-containing parts of the casting material into the mold cavity is reliably prevented.

In einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Verfahrens ist im oberen, dem Bodenbereich gegenüberliegendem Bereich der Gießkammer formseitig mindestens ein Überlaufkanal, der in mindestens einem Überlaufbehälter mündet, ausgebildet. Durch die Ausbildung eines Überlaufkanals und einem Überlaufbehälter erfolgt eine zuverlässige Separierung der oxidbehafteten oberen Gießmaterialschicht in den Überlaufbehälter und ein Überführen des oxidarmen beziehungsweise oxidfreien Gießmaterials aus dem unteren Bereich der Gießkammer in den Formhohlraum. Ein Eindringen des oxidhaltigen Gießmaterials in den Formhohlraum wird somit zuverlässig verhindert.In a further advantageous embodiment of the method according to the invention, the casting chamber is located in the upper region opposite the base region at least one overflow channel on the mold side, which opens into at least one overflow container. The formation of an overflow channel and an overflow container reliably separates the oxide-coated upper casting material layer into the overflow container and transfers the low-oxide or oxide-free casting material from the lower region of the casting chamber into the mold cavity. Penetration of the oxide-containing casting material into the mold cavity is thus reliably prevented.

In einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Verfahrens ist das Gießmaterial eine Schmelze eines Leichtmetalls oder einer Leichtmetall-Legierung, wobei das Leichtmetall insbesondere Aluminium oder Magnesium ist.In a further advantageous embodiment of the method according to the invention, the casting material is a melt of a light metal or a light metal alloy, the light metal being in particular aluminum or magnesium.

Figur 1 zeigt in einer Schnittdarstellung eine Gießkammer 12 einer Druckgießmaschine 10. Man erkennt, dass die Gießkammer 12 formseitig im Bereich eines Bodens 24 zwei Abläufe 16, 18 zum Ablaufen des flüssigen metallischen Druckgießmaterials in die Gießläufe 20 aufweist. Die Gießläufe 20 stehen über Kanäle 36 mit einem Formhohlraum 22 in Verbindung. Des Weiteren erkennt man, dass im oberen, dem Bodenbereich 24 gegenüberliegendem Bereich 34 formseitig ein Überlaufkanal 26 ausgebildet ist, der in einem Überlaufbehälter 28 mündet.FIG. 1 shows a casting chamber 12 of a die casting machine 10 in a sectional illustration. It can be seen that the casting chamber 12 has two outlets 16, 18 in the region of a base 24 for the discharge of the liquid metallic die casting material into the casting barrel 20. The casting runs 20 are connected to a mold cavity 22 via channels 36. Furthermore, it can be seen that an overflow channel 26 is formed on the mold side in the upper area 34 opposite the bottom area 24 and opens into an overflow tank 28.

Figur 2 zeigt eine seitliche Schnittdarstellung der Gießkammer 14 der Druckgießmaschine 10. Man erkennt, dass innerhalb der Gießkammer 12 ein beweglicher Gießkolben 14 angeordnet ist, der während der Vorwärtsbewegung in Richtung des Gießlaufs 20 beziehungsweise des Formhohlraums 22 das Gießmaterial 30 über den Ablauf 16 in den Gießlauf 20 und damit in den Formhohlraum 22 überführt. Der Ablauf 16 (wie auch der nicht dargestellte Ablauf 18) ist dabei formseitig im Bereich des Bodens 24 der Gießkammer 12 angeordnet. In dem oberen, dem Bodenbereich 24 gegenüberliegendem Bereich 34 ist formseitig der Überlaufkanal 26 angeordnet, der mit dem Überlaufbehälter 28 in Verbindung steht. Man erkennt, dass auf der oxidarmen beziehungsweise oxidfreien Schicht des Gießmaterials 30 eine leichtere, das heißt weniger dichte Schicht 32 bestehend aus oxidhaltigen Anteilen des Gießmaterials aufliegt beziehungsweise aufstimmt. Durch die Anordnung der Abläufe 16, 18 im unteren Bereich der Gießkammer 14 und des Überlaufkanals 26 im oberen Bereich der Gießkammer 14 erfolgt eine zuverlässige Separierung der Schichten 30, 32. In den Gießlauf 20 und damit in den Formhohlraum 22 wird nur oxidarmes beziehungsweise oxidfreies Gießmaterial 30 überführt. Das Gießmaterial 30 besteht dabei aus einer Schmelze eines Leichtmetalls oder Leichtmetall-Legierung, wobei das Leichtmetall insbesondere Aluminium oder Magnesium ist.Figure 2 shows a side sectional view of the casting chamber 14 of the die casting machine 10. It can be seen that a movable casting piston 14 is arranged within the casting chamber 12, which during the forward movement in the direction of the casting barrel 20 or the mold cavity 22 the casting material 30 via the outlet 16 in the Casting barrel 20 and thus transferred into the mold cavity 22. The outlet 16 (like the outlet 18, not shown) is arranged on the mold side in the region of the bottom 24 of the casting chamber 12. In the upper area 34 opposite the bottom area 24, the overflow channel 26 is arranged on the mold side and is connected to the overflow tank 28. It can be seen that on the low-oxide or oxide-free layer of the casting material 30 there is a lighter, that is to say less dense layer 32 consisting of oxide-containing parts of the casting material. The arrangement of the drains 16, 18 in the lower region of the casting chamber 14 and of the overflow channel 26 in the upper region of the casting chamber 14 results in a reliable separation of the layers 30, 32. Only low-oxide or oxide-free casting material is placed in the casting run 20 and thus in the mold cavity 22 30 transferred. The casting material 30 consists of a melt of a light metal or light metal alloy, the light metal being in particular aluminum or magnesium.
