Description

Die Erfindung betrifft ein Druckgiessverfahren unter Verwendung von Metallschmelzen, besonders bevorzugt von Aluminium-, Magnesium- oder Zinkwerkstoffen zur Herstellung von Druckgussteilen.The invention relates to a die casting method using metal melts, particularly preferably of aluminum, magnesium or zinc materials for the production of die-cast parts.

Die Herstellung von Druckgussteilen aus leichtmetallischen Schmelzen heraus ist bekannt. Hierzu wird eine Portion Schmelze in eine Giesskammer gefüllt und mittels eines Giesskolbens in eine Formkavität gepresst.The production of die castings from light metal melts out is known. For this purpose, a portion of melt is filled into a casting chamber and pressed by means of a casting piston into a mold cavity.

Es ist nach der DE-C-10064300 bekannt, einen Giesslauf einer Form so auszubilden, dass er einen Pfropfenaufnahmeraum für einen in einer Düse gebildeten und zu entfernenden Materialpfropfen aufweist, wobei der Giesslauf mindestens einen Laufkanal enthält, welche jeweils abschnittsweise als Pfropfenaufnahmeraum ausgebildet sind.It is after the DE-C-10064300 It is known to design a casting run of a mold in such a way that it has a plug receiving space for a material plug formed and to be removed in a nozzle, wherein the run contains at least one running channel, which are each formed in sections as a plug receiving space.

Die DE-A-4326325 offenbart ein Verfahren zum wahlweisen Entleeren eines metallurgischen Gefässes. Das Gefäss verfügt im Bodenbereich über einen Entleerungsstutzen, in dem ein Teil des Gefässinhaltes zum Erstarren gebracht wird, so dass ein Pfropfen entsteht. Der so verschlossene Entleerungsstutzen lässt sich dadurch öffnen, dass der Pfropfen zum Schmelzen gebracht wird. Hierzu ist dem Entleerungsstutzen eine Induktionsheizung zugeordnet.The DE-A-4326325 discloses a method for selectively draining a metallurgical vessel. The vessel has a drain port in the bottom area, in which a part of the vessel contents is solidified, so that a plug is formed. The thus closed drainage nozzle can be opened by causing the plug to melt. For this purpose, the discharge nozzle is associated with an induction heater.

In der EP-A-1201335 ist eine Warmkammer-Giessmaschine offenbart, die einen Giesskolben 5 mit einer Öffnung zur Form beinhaltet und ein Heisskanalsystem aufweist. Ein Pfropfen verschliesst ein zusätzliches Mundstück zwischen Düse und Anguss und soll lediglich einen Rückfluss aus der Form verhindern, was einen separaten Aufnahmeraum erfordert. Es wird ein Pfropfen weitab von der Giesskammer in einem zusätzlichen Mundstück zwischen Anguss und einer beheizten Düse gebildet.In the EP-A-1201335 discloses a hot-chamber casting machine including a casting piston 5 with an opening to the mold and having a hot runner system. A plug closes an additional mouthpiece between nozzle and sprue and is only intended to prevent backflow from the mold, which requires a separate receiving space. A plug is formed far from the casting chamber in an additional mouthpiece between the gate and a heated nozzle.

Die DE-A-10359692 betrifft eine Spritzgiesseinrichtung für Kunststoffe, wobei eine Nadel zusätzlich hinter einem Pfropfen angeordnet ist, die den Pfropfen entfernen soll.The DE-A-10359692 relates to an injection molding device for plastics, wherein a needle is additionally arranged behind a plug which is to remove the plug.

In der DE-A-3831938 ist hingegen eine Giessvorrichtung mit lediglich einem mechanischen Verschluss des Angusskanals mittels Schliessstange offenbart.In the DE-A-3831938 On the other hand, a casting device with only one mechanical closure of the sprue channel by means of a closing rod is disclosed.

Die DE-A-10039589 beinhaltet ein vom Spritzaggregat getrenntes, mechanisches Verschliesselement, mit dem eine Düse nach dem Einspritzen vom Schmelzgut verschliessbar ist.The DE-A-10039589 includes a separate from the injection unit, mechanical closure element with which a nozzle after injection from the melt is closed.

Eine Vorrichtung zur Herstellung von Metallgussteilen im Niederdruckbereich gemäss EP-B-1458905 bezweckt eine Verhinderung des Rückflusses von Schmelze aus der Giesskammer mittels gesteuerter Ventile, ähnlich zu einer Giesseinrichtung nach US-A-3800986 .A device for the production of metal castings in the low pressure range according to EP-B-1458905 The purpose of the invention is to prevent the backflow of melt from the casting chamber by means of controlled valves, similar to a casting device US-A-3800986 ,

Der Erfindung liegt die Aufgabe zugrunde, ein Druckgiessverfahren zu entwickeln, bei dem eine formseitige Öffnung einer Giesskammer verschliessbar ist, dies auch durch das zu vergiessende Material selbst, ein Aluminium-, Magnesium- oder Zinkwerkstoff so dass keine mechanisch bewegten Verschlüsse erforderlich sind.The invention has for its object to develop a die casting in which a mold-side opening of a casting chamber is closed, this also by the material to be cast itself, an aluminum, magnesium or zinc material so that no mechanically moving closures are required.

Die Lösung der Aufgabe erfolgt mit den Merkmalen des Patentanspruchs. Die formseitige Öffnung der Giesskammer zur Form resp. zum Angusskanal wird durch einen Materialverschluss gebildet. Dieser Materialverschluss ist ein Pfropfen, der auch scheibenförmig sein kann und aus zumindest teilerstarrtem Material (Giesswerkstoff) besteht.The solution of the problem is achieved with the features of the claim. The mold-side opening of the casting chamber to form resp. to the sprue is formed by a material closure. This material closure is a plug, which may also be disc-shaped and consists of at least teilerstarrtem material (casting material).

Vor dem nächsten Schuss ist dieser Pfropfen zumindest partiell aufzuschmelzen, wozu die Energie der in die Giesskammer nachgefüllten Schmelze und/oder einer Heizeinrichtung verwendet wird.Before the next shot, this plug is to be at least partially melted, for which purpose the energy of the melt replenished in the casting chamber and / or a heating device is used.

Die Pfropfbildung kann bei einzelnen wie auch bei Mehrfachanschnitten erfolgen. Die Ausbildung von Pfropfen ist auf dem gesamten Weg zum Anschnitt wie auch im Anschnitt selbst möglich. Mehrfachpfropfen bzw. Pfropfen in mehreren Angusskanälen sind ebenfalls möglich.The grafting can be done in single as well as in multiple cuts. The formation of plugs is possible on the entire way to the gate as well as in the gate itself. Multiple grafting or grafting in multiple runners are also possible.

Der Giesskolben muss beim aktuellen Schuss vor dem zu bildenden Pfropfen stehen bleiben.The casting piston must stop at the current shot in front of the stopper to be formed.

Es werden keine mechanisch bewegten Verschlusselemente benötigt und es entsteht kein resp. kein substantieller Materialverlust, doch kann das Verschliessen durch mechanisch bewegte oder andere Verschlusselemente, insbesondere unabhängig voneinander wirkende Elemente ergänzt werden.There are no mechanically moving closure elements needed and there is no resp. no substantial loss of material, but the closure can be supplemented by mechanically moving or other closure elements, in particular independently acting elements.

Die Erfindung wird nachfolgend in Ausführungsbeispielen anhand einer Zeichnung näher beschrieben. Die Zeichnung zeigt in den Fig. 1 und 2 schematisiert Teile einer Druckgiessmaschine.The invention will be described in more detail in exemplary embodiments with reference to a drawing. The drawing shows in the Fig. 1 and 2 schematized parts of a die casting machine.

Eine nicht vollständig dargestellte Druckgiessmaschine weist eine Giesskammer 1 mit einem Giesskolben 2 auf. Die Giesskammer 1 weist einen Stutzen 3 zum Andocken eines Dosierrohres 5 für ein Dosieren von unten oder alternativ eine Öffnung für ein Dosieren von oben auf. Die Öffnung für ein Dosieren von oben kann aber auch als Gegenloch zur Entlüftung der Giesskammer 1 verwendet werden (Abbau von Gegendruckwellen).A die casting machine, not fully shown, has a casting chamber 1 with a casting piston 2. The casting chamber 1 has a nozzle 3 for docking a dosing tube 5 for dosing from below or alternatively an opening for dosing from above. The opening for dosing from above can also be used as a counter hole be used for venting the casting chamber 1 (reduction of counter-pressure waves).

Eine dem Giesskolben 2 gegenüberliegende stirnseitige Öffnung 7 zu einem Angusskanal der Formkavität einer Form ist vollständig abdichtbar.A casting piston 2 opposite the frontal opening 7 to a sprue of the mold cavity of a mold is completely sealed.

Diese Abdichtung der Öffnung 7 wird durch einen Pfropfen 4 aus dem zu vergiessenden Material erreicht. Gebildet wird dieser Pfropfen durch "überschüssige" Metallschmelze, indem der Giesskolben 2 nach einer Füllung der Giesskammer 1 soweit in Richtung der Öffnung 7 verfahren wird, dass die Formkavität vollständig mit Metallschmelze gefüllt wird und ein Schmelzerest in der Giesskammer 1 vor der Öffnung 7 verbleibt. Dieser Schmelzerest erstarrt zumindest teilweise und bildet so den Pfropfen 4. Nach dem Rückfahren des Giesskolbens 2 und der Füllung der Giesskammer 1 für den nächsten Schuss wird der Pfropfen 4 beim oder vor dem Vorfahren des Giesskolbens 2 mittels einer Heizung 10 zumindest teilweise wieder aufgeschmolzen. Ggf, kann auch die Wärme der Metallschmelze mit genutzt werden. Die Heizung der Schmelze erfolgt wie dargestellt mit einer eingefügten Heizung 10 oder mittels eines Doms resp. Torpedos 11, welches als separates Element im Schmelzekanal 13 angeordnet ist.This seal of the opening 7 is achieved by a plug 4 of the material to be poured. This plug is formed by "excess" molten metal by the casting piston 2 is moved so far in the direction of the opening 7 after a filling of the casting chamber 1 that the mold cavity is completely filled with molten metal and a Schmelzerest in the casting chamber 1 in front of the opening 7 remains. After melting the casting piston 2 and filling the casting chamber 1 for the next shot, the plug 4 is at least partially remelted during or before the ancestor of the casting piston 2 by means of a heater 10. If necessary, the heat of the molten metal can also be used. The heating of the melt takes place as shown with an inserted heater 10 or by means of a dome resp. Torpedoes 11, which is arranged as a separate element in the melt channel 13.

In weiterer Ausbildung kann hierbei die Schmelzezufuhr über ein Dosierventil 12 geregelt sein, wobei die Schmelze auch an der Stirnseite der Giesskammer 1 durch eine Eintrittsöffnung 9 in diese gelangt und durch eine Austrittsöffnung 8 (entsprechend der vorgenannten Öffnung 7) von dieser in die Form gepresst wird und dabei durch den Torpedo 11 aufgeheizt wird.In a further embodiment, in this case the melt supply via a metering valve 12 may be regulated, wherein the melt also passes at the end face of the casting chamber 1 through an inlet opening 9 in this and is pressed by an outlet opening 8 (corresponding to the aforementioned opening 7) of this in the mold and is heated by the torpedo 11.

Nach der Ausführungsform wird eine Zuleitung (Dosierrohr 5) der Schmelze von einem Ofen nach dem Füllen der Giesskammer 1 und vor dem Füllen der Formkavität durch einen zweiten Pfropfen 4' verschlossen.According to the embodiment, a feed line (metering tube 5) of the melt from an oven after filling the casting chamber 1 and before filling the mold cavity by a second plug 4 'is closed.
