Description

Gießvorrichtung  caster
Die Erfindung betrifft eine Gießvorrichtung zum Nieder- oder Gegendruckgießen, wobei die Gießvorrichtung zumindest eine untere Kammer für zumindest einen Ofen und zumindest eine obere Kammer für zumindest eine Kokille aufweist und die obere und die untere Kammer durch zumindest eine untere Formaufspannplatte zur Befestigung eines Unterteils der zumindest einen Kokille voneinander getrennt sind. Weiters betrifft die Erfindung eine Anlage zur Herstellung eines Werkstückes mittels Niederdruck- oder Gegendruckgießens. The invention relates to a casting device for low- or counter-pressure casting, wherein the casting device has at least one lower chamber for at least one furnace and at least one upper chamber for at least one mold and the upper and lower chambers by at least one lower platen for fixing a lower part of at least a mold are separated from each other. Furthermore, the invention relates to a plant for the production of a workpiece by means of low-pressure or counter-pressure casting.
Anlagen mit einer Gießvorrichtung insbesondere zum Gießen unter einem durch eine Gasphase erzeugten Druck finden in der Gießereitechnik, insbesondere für die Herstellung von Guss- stücken mit hohen physikalischen und mechanischen Kennwerten, insbesondere aus Leichtmetall-Legierungen, Anwendung. Systems with a casting device, in particular for casting under a pressure generated by a gas phase, are used in foundry technology, in particular for the production of castings with high physical and mechanical characteristics, in particular light metal alloys.
Der eigentliche Gießvorgang erfolgt sowohl beim Niederdruck-Gießverfahren als auch beim Gegendruck-Kokillengießverfahren mit Hilfe eines Steigrohres, durch das die Schmelze nach oben in die Kokille gefördert wird. The actual casting process takes place both in the low-pressure casting process and in the counter-pressure Kokillengießverfahren using a riser, through which the melt is conveyed up into the mold.
Die Druckbeaufschlagung der Schmelze im Ofen zum Hochfördern der Schmelze in die Kokille wird jedoch beim Gegendruck-Kokillengießverfahren durch eine Druckdifferenz herbeigeführt, indem der Gasdruck in der Kokille etwas abgesenkt wird. Dadurch entsteht ein Über- druck im Gießofen, der für das Hochsteigen der Schmelze in die Kokille ausreicht. However, the pressurization of the melt in the furnace to convey the melt up into the mold is brought about in the counterpressure die casting process by a pressure difference by slightly lowering the gas pressure in the mold. This creates an overpressure in the casting furnace, which is sufficient for the melt to rise into the mold.
Eine Gießvorrichtung und eine Anlage der eingangs genannten Art sind beispielsweise aus der DE102010026480A1 bekannt geworden. Bei den bekannten Lösungen ist die Formaufspannplatte, durch welche die untere Kammer von der oberen Kammer getrennt ist, orts- fest montiert und kann nicht in ihrer Position verändert werden. Um den Ofen mit der Kokille über ein Steigrohr zu verbinden, wird der Ofen nachdem er in der unteren Kammer positioniert worden ist, angehoben. Dies hat jedoch den Nachteil, dass zum einen eine sehr hohe Masse bewegt werden muss und dieser Vorgang zum anderen ein schnelles Austauschen eines Ofens für einen neuen Gießvorgang relativ zeitaufwendig ist. Nachteilig ist es weiters, dass bei den bekannten Lösungen zwei Hubwerke bzw. Antriebe erforderlich sind, da sowohl der Ofen als auch die obere Formaufspannplatte bewegt werden müssen. Was auch die Bauhöhe wesentlich vergrößert. A casting apparatus and a plant of the type mentioned are known for example from DE102010026480A1. In the known solutions, the platen, by which the lower chamber is separated from the upper chamber, fixed in place and can not be changed in position. To connect the oven to the mold via a riser, the oven is raised after being positioned in the lower chamber. However, this has the disadvantage that on the one hand a very high mass must be moved and this process on the other hand, a quick replacement of a Furnace is relatively time consuming for a new casting process. Another disadvantage is that in the known solutions two hoists or drives are required because both the furnace and the upper platen must be moved. Which also significantly increases the height.
Es ist daher eine Aufgabe der Erfindung, die oben genannten Nachteile des Stands der Technik zu überwinden. It is therefore an object of the invention to overcome the above-mentioned disadvantages of the prior art.
Diese Aufgabe wird mit einer Vorrichtung der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass die Formaufspannplatte in einer vertikalen Richtung verlagerbar ist. This object is achieved with a device of the type mentioned according to the invention in that the mold mounting plate is displaceable in a vertical direction.
Durch die vertikale Bewegbarkeit der unteren Formaufspannplatte kann diese nach oben bewegt werden, wodurch der zur Manipulation des Ofens zur Verfügung stehende Raum in der unteren Kammer vergrößert wird. Auf diese Weise kann der Ofen auf einfache Weise in der Kammer positioniert und wieder entnommen werden. Darüber hinaus ist es möglich, den in der unteren Kammer positionierten Ofen ohne ein vertikales Anheben desselben mit der Kokille zu verbinden, in dem die obere Formplatte abgesenkt wird. An dieser Stelle sei darauf hingewiesen, dass die untere und die obere Kammer jeweils hermetisch, insbesondere gasdicht, abgedichtet sein können. Auch könne die obere und/oder untere Kammer evakuiert oder mit einem Schutzgas befüllt sein. Darüber hinaus spart die erfindungsgemäße Lösung den zweiten Antrieb zum Anheben des Ofens ein, wodurch sich auch die Bauhöhe wesentlich verringern lässt. Due to the vertical mobility of the lower platen this can be moved upwards, whereby the space available for manipulation of the furnace in the lower chamber is increased. In this way, the oven can be easily positioned in the chamber and removed again. Moreover, it is possible to connect the furnace positioned in the lower chamber to the mold without raising it vertically, by lowering the upper mold plate. It should be noted at this point that the lower and the upper chamber can each be hermetically, in particular gas-tight, sealed. Also, the upper and / or lower chamber may be evacuated or filled with a protective gas. In addition, the solution according to the invention saves the second drive for lifting the furnace, whereby the overall height can be significantly reduced.
Gemäß einer vorteilhaften Variante der Erfindung kann es vorgesehen sein, dass die zumin- dest eine untere Formaufspannplatte zumindest ein Steigrohr zur Verbindung des zumindest einen Ofens mit der zumindest einen Kokille aufweist. Die Anordnung des Steigrohres an der unteren Formaufspannplatte hat den Vorteil, dass durch Anheben der untere Formaufspannplatte das Steigrohr mitangehoben wird, wodurch das Steigrohr sehr schnell aus dem Bereich des Ofens entfernt und der Ofen sehr schnell ausgewechselt werden kann. Insbesondere ist es hierbei von Vorteil, wenn eine Unterkante des Steigrohrs über eine Oberkante des Ofens angehoben wird, da der Ofen dann in horizontaler Richtung ohne Behinderung durch das Steigrohr aus der Kammer entnommen bzw. in diese eingeführt werden kann. Alternativ zur Mon- tage des Steigrohres an der unteren Formaufspannplatte wäre es jedoch auch möglich, das Steigrohr getrennt von der Formaufspannplatte zu bewegen. According to an advantageous variant of the invention, it can be provided that the at least one lower platen has at least one riser pipe for connecting the at least one furnace to the at least one mold. The arrangement of the riser to the lower platen has the advantage that the riser is lifted by lifting the lower platen, whereby the riser very quickly removed from the range of the furnace and the furnace can be replaced very quickly. In particular, it is advantageous in this case if a lower edge of the riser pipe is raised above an upper edge of the furnace, since the furnace can then be removed from the chamber or inserted into it in the horizontal direction without being impeded by the riser pipe. Alternatively to However, it would also be possible to move the riser separately from the platen during the days of the riser to the lower platen.
Bei einer vorteilhaften Weiterbildung der Erfindung kann es vorgesehen sein, dass die obere Kammer eine obere Formaufspannplatte für einen Oberteil der zumindest einen Kokille aufweist. Die obere Formaufspannplatte kann Haltelemente und gegebenenfalls Medienschnittstellen für den Oberteil der Kokille aufweisen. In an advantageous embodiment of the invention, it may be provided that the upper chamber has an upper platen for an upper part of the at least one mold. The upper platen may have holding elements and optionally media interfaces for the upper part of the mold.
Besonders bevorzugt ist die obere Formaufspannplatte in vertikaler Richtung verschiebbar gelagert und mit ersten Verbindungselementen verbunden, wobei die untere Formaufspannplatte mit zweiten Verbindungselementen verbunden ist, wobei jedes der ersten Verbindungselemente mit einem entsprechenden Verbindungselement der zweiten Verbindungselemente durch eine vertikale Verschiebung der oberen Formaufspannplatte in Richtung der unteren Formaufspannplatte in Eingriff gebracht ist. Diese Variante der Erfindung hat den Vorteil, dass die obere Formaufspannplatte und die untere Formaufspannplatte gemeinsam bewegt werden können. So kann durch eine Hub- oder Senkbewegung der oberen Formaufspannplatte die untere Formaufspannplatte mitangehoben oder abgesenkt werden. Dies ist unter Anderem in Hinblick auf Reduktion der für die Bewegung der Formauf spannplatten erforderlichen Antriebselemente von Vorteil. Darüber hinaus lassen sich auf diese Weise die Bewegungen der beiden Formaufspannplatten mit geringem Aufwand synchronisieren, was vor allem bei einem schnellen Austausch von Ofen und/oder der darüber angeordneten Kokille von Vorteil ist. Particularly preferably, the upper platen is slidably mounted in the vertical direction and connected to first connecting elements, wherein the lower platen is connected to second connecting elements, wherein each of the first connecting elements with a corresponding connecting element of the second connecting elements by a vertical displacement of the upper platen in the direction of the lower Platen is brought into engagement. This variant of the invention has the advantage that the upper platen and the lower platen can be moved together. So can be mitaufhoben or lowered by a lifting or lowering the upper platen, the lower platen. This is advantageous, inter alia, with regard to reducing the drive elements required for the movement of the mold mounting plates. In addition, can be synchronized in this way, the movements of the two platens with little effort, which is especially in a quick exchange of furnace and / or the mold disposed above advantage.
Hinsichtlich einer zuverlässigen Verbindung von oberer und unterer Formaufspannplatte ist es besonders von Vorteil, wenn jedes der ersten Verbindungselemente mit dem jeweils zugehörigen zweiten Verbindungselement je einen form- und/oder kraftschlüssigen Verschluss bildet. Die Verschlüsse können im Bedarfsfall wieder gelöst und beispielsweise die obere Formaufspannplatte gegenüber der unteren Formaufspannplatte verfahren werden. Besonders vorteilhaft ist es wenn eines der Verbindungselemente in dem zugehörigen anderen Verbin- dungsei ement einrastet, sobald eines der beiden Verbindungselemente in das andere Verbindungselement oder die beiden Verbindungselemente ineinander geschoben werden. Dies ermöglicht ein sehr rasches und automatisches Verbinden der unteren und der oberen Formaufspannplatte allein durch eine vertikale Verschiebung der oberen Formaufspannplatte. Gemäß einer vorteilhaften Weiterbildung der Erfindung kann es vorgesehen sein, dass die obere Formaufspannplatte mit Aktoren zum Anheben oder Absenken der oberen Formaufspannplatte verbunden ist. Die Anbindung der oberen Formaufspannplatte an Aktoren hat den Vorteil, dass die obere Formaufspannplatte sowohl gegenüber der unteren Formaufspannplatte als auch gemeinsam mit dieser bewegt werden kann. Eine Bewegung der oberen Formaufspannplatte unabhängig von der unteren Formaufspannplatte ist vor allem bei einer Beschickung der oberen Kammer mit einer Kokille von Vorteil, da durch Anheben der oberen Formaufspannplatte der zur Beschickung zur Verfügung stehende Raum der oberen Kammer vergrößert werden kann. So kann eine in der Kammer befindliche Kokille in einem geschlossenen Zustand (Ober- und Unterteil miteinander verbunden) von der oberen Formaufspannplatte angehoben werden und mittels eines Manipulator auf einen Transportschlitten verladen werden. Bei einem Beschicken der oberen Kammer kann die obere Formaufspannplatte mit dem Oberteil der geschlossenen Kokille verbunden werden. Durch ein Absenken der oberen Formaufspannplatte kann die Kokille mit der unteren Formaufspannplatte in Verbindung gebracht werden und im Bedarfsfall der Oberteil von dem Unterteil der Kokille gelöst werden. Eine gemeinsame Bewegung von unterer und oberer Formaufspannplatte ist wie bereits oben erwähnt vor allem hinsichtlich der Beschickung der unteren Kammer mit einem Ofen und seiner Entnahme von dort von Vorteil. With regard to a reliable connection of the upper and lower platen, it is particularly advantageous if each of the first connecting elements with the respectively associated second connecting element forms a positive and / or non-positive closure. If necessary, the closures can be released again and, for example, the upper platen can be moved relative to the lower platen. It is particularly advantageous if one of the connecting elements engages in the associated other connecting element as soon as one of the two connecting elements is pushed into one another in the other connecting element or the two connecting elements. This allows a very quick and automatic connection of the lower and the upper mold clamping plate solely by a vertical displacement of the upper mold mounting plate. According to an advantageous embodiment of the invention, it may be provided that the upper platen is connected to actuators for raising or lowering the upper platen. The connection of the upper platen to actuators has the advantage that the upper platen can be moved both with respect to the lower platen and together with this. A movement of the upper platen independent of the lower platen is especially in a feed of the upper chamber with a mold advantage because it can be increased by lifting the upper platen of the available space for loading the upper chamber. Thus, a mold located in the chamber in a closed state (upper and lower part connected to each other) are lifted from the upper platen and loaded by means of a manipulator on a transport carriage. When loading the upper chamber, the upper platen can be connected to the upper part of the closed mold. By lowering the upper platen, the mold can be associated with the lower platen and be solved in case of need, the upper part of the lower part of the mold. A common movement of lower and upper platen is as already mentioned above, especially with regard to the loading of the lower chamber with an oven and its removal from there an advantage.
Bei einer besonders günstigen Variante der Erfindung kann es vorgesehen sein, dass die Aktoren als Kolben/Zylindereinheiten, insbesondere als Hydraulikzylinder, ausgebildet sind, wobei Kolben der Kolben/Zylindereinheiten mit der oberen Formaufspannplatte verbunden und Arbeitszylinder der Kolben/Zylindereinheiten unter den jeweils zugehörigen Kolben angeordnet und abgestützt sind. Durch diese Anordnung der Kolben/Zylindereinheiten kann eine geringe Bauhöhe realisiert werden, da die Kolben die obere Formaufspannplatte nach oben drücken. Bei einer anderen Anordnung würden die Kolben die Formaufspannplatte nach oben ziehen und die Zylinder müssten über der Formaufspannplatte hängend angeordnet sein, wodurch sich die Bauhöhe vergrößern würde. Auch können bei dieser Variante der Erfindung höhere auf die Kolben wirkende Kräfte realisiert werden als dies bei einer Anordnung, bei welcher die Kolben die obere Formaufspannplatte nach oben ziehen, der Fall ist, da die Kraft auf die gesamte zur Verfügung stehende Querschnittsfläche des Kolbens und nicht nur auf eine ringförmige Fläche ausgeübt werden kann. Gemäß einer weiteren vorteilhaften Ausführungsform kann die Gießvorrichtung eine Säulen- gießvorrichtung sein, welche ein Gestell mit Säulen aufweist, die zwischen einer Grundplatte und einer Deckstruktur der Gießvorrichtung angeordnet sind, wobei die Deckstruktur eine x- förmige Grundform aufweist. Durch die besondere Ausbildung der Deckstruktur können thermisch induzierte Spannungen besonders gut abgebaut werden, ohne dass es zu Zwängungen kommt, wie dies bei einer plattenförmigen Ausbildung der Deckstruktur der Fall sein kann. Darüber hinaus ermöglicht die x-förmige Deckstruktur eine besonders gute Zugänglichkeit der Gießvorrichtung von oben. In a particularly favorable variant of the invention it can be provided that the actuators are designed as piston / cylinder units, in particular as hydraulic cylinders, with pistons of the piston / cylinder units connected to the upper platen and working cylinder of the piston / cylinder units arranged under the respectively associated pistons and supported. By this arrangement, the piston / cylinder units a low height can be realized because the pistons push the upper platen upwards. In another arrangement, the pistons would pull the platen up and the cylinders would have to be placed over the platen hanging, which would increase the height. Also, in this variant of the invention higher forces acting on the piston can be realized than in an arrangement in which the pistons pull the upper platen upwards, the case is because the force on the entire available cross-sectional area of the piston and not can only be exercised on an annular surface. According to a further advantageous embodiment, the casting device can be a column casting device which has a frame with columns which are arranged between a base plate and a cover structure of the casting device, the cover structure having an x-shaped basic shape. Due to the special design of the cover structure thermally induced stresses can be broken down particularly well, without causing constraints, as can be the case with a plate-shaped design of the cover structure. In addition, the x-shaped cover structure allows a particularly good accessibility of the casting device from above.

The actuators 24 are formed in the illustrated embodiment as a piston / cylinder units, in particular as a hydraulic cylinder. Pistons 26 of the piston / cylinder units are in this case connected to the upper platen 12. Working cylinder 25 of the piston / cylinder units are arranged and supported under the associated pistons 26, for example on a frame of the casting device 10. According to Fig. 1, the casting apparatus 10 may be formed as a column caster, which has a frame with columns 27 which between a base plate 28 and a
Deckstruktur 19 der Gießvorrichtung 10 angeordnet sind. Die Deckstruktur 19 weist bei der dargestellten Ausführungsform eine x-förmige Grundform auf. Eine Gießvorrichtung mit der in Fig. 1 gezeigten Deckplatte ist eine gegebenenfalls für sich eigenständige Ausführungsform einer Gießvorrichtung, die auch unabhängig von der Anordnung einer beweglichen, unteren Formplatte 15 und den anderen wesentlichen Merkmalen der gegenständlichen Erfindung realisiert sein kann. Der mit Schmelze versehene Ofen 4 und der durch die beiden Kokillenteile im geschlossenen Zustand ausgebildete Gießformhohlraum sind gemäß Fig. 2 über ein Steigrohr 23 miteinander verbunden, welches an der unteren Formaufspannplatte 15 montiert sein kann. Das Steigrohr 23 folgt bei der dargestellten Ausführungsform einer Bewegung der unteren Formaufspannplatte 15. Deck structure 19 of the casting apparatus 10 are arranged. The cover structure 19 has an x-shaped basic shape in the illustrated embodiment. A casting apparatus with the cover plate shown in Fig. 1 is an optionally independent embodiment of a casting apparatus, which may also be realized independently of the arrangement of a movable lower mold plate 15 and the other essential features of the subject invention. The furnace 4 provided with the melt and the mold cavity formed by the two mold parts in the closed state are interconnected by means of a riser 23 as shown in FIG. 2, which can be mounted on the lower mold mounting plate 15.

Between the spaced apart in Fig. 1 and 2 juxtaposed two casting devices 10, a manipulator 21 may be arranged for handling the workpieces.
Weiters kann eine Führung 28 vorgesehen sein, die in dem dargestellten Beispiel durch ein Schienensystem realisiert ist, auf der ein Transportschlitten 6 zur Aufnahme bzw. Entnahme und Abgabe bzw. Überführung des Ofens 4 angeordnet ist. Furthermore, a guide 28 may be provided, which is realized in the illustrated example by a rail system on which a transport carriage 6 for receiving or removal and delivery or transfer of the furnace 4 is arranged.
Der Transportschlitten 6 pendelt hierbei zwischen den Gießvorrichtungen 10 und einer entfernt davon liegenden Bereitstellungsposition, beispielswiese einer Station 8 zur Aufbereitung der Schmelze. The transport carriage 6 in this case oscillates between the casting devices 10 and a supply position remote therefrom, for example a station 8 for processing the melt.
In Fig. 3 ist dargestellt, wie der Transportschlitten vor einer Gießvorrichtung 10 hält, um einen mit Schmelze befüllten Ofen 4 aus seiner Ofenpositionierstelle in die, noch nicht mit einem Ofen 4 versehene Gießvorrichtung 10 zu überführen. Zuvor hat der Transportschlitten 6 diesen Ofen 4 unter Hinterlassen einer freien Stelle an der Station 8 aufgenommen. GemäßFIG. 3 shows how the transport carriage stops in front of a casting device 10 in order to transfer a furnace 4 filled with melt from its furnace positioning point into the casting device 10, which has not yet been provided with an oven 4. Previously, the transport carriage 6 has received this oven 4 leaving a vacant location at the station 8. According to
Fig. 1 weist der Transportschlitten 6 eine weitere Ofenpositionierstelle 29 auf. Dadurch ist ein zeitsparender Wechsel eines leeren in der Gießvorrichtung 10 angeordneten Ofens 4 gegen einen mit Schmelze gefüllten Ofen 4 möglich. Der Transportschlitten 6 nimmt zunächst den mit Schmelze gefüllten Ofen 4 in einer ersten Ofenpositionierstelle 20 aus der Station 8 auf, fährt anschließend zur Gießvorrichtung 10, um dort den leeren Ofen 4 in die zweite, noch freie Ofenpositionierstelle 29 aufzunehmen, überführt anschließend den mit Schmelze versehenen Ofen 4 aus der ersten Ofenpositionierstelle 20 in die ofenlose Gießvorrichtung 10, um schließlich den bereits aufgenommenen leeren Ofen 4 zur Station 8 mitzunehmen, damit dieser in eine freie Stelle der Station 8 zur Neubeschickung mit Schmelze überführt werden kann. Fig. 1, the transport carriage 6 on another Ofenpositionierstelle 29. As a result, a time-saving change of an empty in the casting apparatus 10 arranged furnace 4 is possible against a furnace 4 filled with melt. The transport carriage 6 first takes the Furnace-filled oven 4 in a first oven-positioning station 20 from station 8 then travels to the caster 10 to receive the empty oven 4 into the second oven-positioning station 29 which is still free, then transfers the oven-4-oven from the first oven-locator 20 in the oven-less pouring device 10, to finally take the already taken empty oven 4 to the station 8, so that it can be transferred to a vacancy of the station 8 for reloading with melt.
Der Transportschlitten 6 kann zwei über einander angeordnete Böden aufweisen, wobei ein unterer Boden für den Transport des Ofens 4 und ein oberer Boden 18 für einen Transport zumindest einer Kokille vorgesehen ist. Zur Aufnahme der Kokillen kann der Transportschlitten 6 bei einer Bühne 9 anhalten und die dort bereitgestellten Kokillen von der Bühne 9 auf die obere Ebene überführen. Anschließend kann der mit dem Ofen 4 und der Kokille beladene Transportschlitten zu einer der Gießvorrichtungen 10 fahren. Das Überführen der Kokillen auf und von dem Transportschlitten 6 kann mittels Werkzeugwagen 7 erfolgen. The transport carriage 6 may have two floors arranged above one another, wherein a lower floor is provided for the transport of the oven 4 and an upper floor 18 for a transport of at least one mold. To accommodate the molds, the transport carriage 6 can stop at a stage 9 and transfer the molds provided there from the stage 9 to the upper level. Subsequently, the loaded with the oven 4 and the mold transport carriage can go to one of the casting devices 10. The transfer of the molds on and from the transport carriage 6 can be done by means of tool carriage 7.
