Der Erfindung liegt die Aufgabe zugrunde, bei einer Gießanordnung mit einer mindestens zwei Gießkavitäten zum Gießformen jeweils eines Gussteils umschließenden Gießform die zerstörungsfreie Entformbarkeit mit dem Ziel des Gießens auch komplexerer Gussteile zu verbessern.The invention is based on the object at a casting assembly with a least two Gießkavitäten for molding each of a casting mold surrounding to improve the non-destructive release properties with the aim of molding of more complex castings.

Zur Lösung dieser Aufgabe wird eine Gießanordnung mit den Merkmalen des Patentanspruchs 1 vorgeschlagen.To solve this problem, a casting arrangement with the features of claim 1 is proposed.

Bei dieser Anordnung sind die Seitenteile in der zweiten Entformungsrichtung beweglich angeordnet, außerdem sind die ersten Formstücke jeweils an Führungen abgestützt, die an der ersten Grundplatte ausgebildet sind und sich in der zweiten Entformungsrichtung erstrecken, wobei die ersten Formstücke längs der Führungen beweglich angeordnet sind.In this arrangement, the side parts are arranged movable in the second Entformungsrichtung, also the first fittings are each supported on guides which are formed on the first base plate and extending in the second Entformungsrichtung, wherein the first mold pieces are arranged to be movable along the guides.

Mit dieser Anordnung wird ein hohes Maß allseitiger Entformbarkeit erzielt, wodurch sich auch komplex gestaltete Gussteile gießen lassen, ohne dass einzelne Formstücke nach dem Guss zwecks Entformung zerstört werden müssen. Die Gießanordnung eignet sich daher in besonderer Weise für größere Serien ohne die Notwendigkeit, einzelne Formstücke jeweils neu herstellen zu müssen, z. B. aus verfestigtem Formsand.With this arrangement, a high degree of all-round releasability is achieved, which can be cast even complex shaped castings without individual fittings must be destroyed after demolding for casting. The casting assembly is therefore particularly suitable for larger series without the need to produce individual fittings each new, z. B. from solidified sand.

Das Gießen kann sowohl mit einem 3-Plattenwerkzeug, also mit einem Schusskolben und einer Schusskammer, als auch mit einem 2-Plattenwerkzeug, also mit zwei parallel und gleichzeitig arbeitenden Schusskolben und zwei Schusskammern durchgeführt werden.The casting can be carried out both with a 3-plate tool, ie with a firing piston and a firing chamber, as well as with a 2-plate tool, ie with two parallel and simultaneously working firing pistons and two shot chambers.

Mit einer Ausgestaltung der Gießanordnung wird vorgeschlagen, dass die Führungen gleichgerichtet und vorzugsweise zueinander fluchtend angeordnet sind.With an embodiment of the casting arrangement, it is proposed that the guides are rectified and preferably aligned with each other.

Mit einer anderen Ausgestaltung werden Anschläge an der ersten Grundplatte vorgeschlagen, welche die Bewegungsmöglichkeit der ersten Formstücke in Richtung aufeinander zu begrenzen.With another embodiment, stops are proposed on the first base plate, which limit the possibility of movement of the first fittings in the direction of each other.

Mit einer weiteren Ausgestaltung wird vorgeschlagen, dass die ersten Formstücke jeweils aus einem die Gestalt der jeweiligen Gießkavität bestimmenden Formabschnitt und einem Trägerabschnitt bestehen, wobei nur der Trägerabschnitt an der Führung abgestützt ist.With a further embodiment, it is proposed that the first shaped pieces each consist of a shape section defining the shape of the respective casting cavity and a carrier section, wherein only the carrier section is supported on the guide.

Gemäß einer weiteren Ausgestaltung der Gießanordnung erstreckt sich die Führung bis hinter das fünfte Formstück, wobei sich ein Teil des Trägerabschnitts zwischen der Führung und dem fünften Formstück befindet.According to a further embodiment of the casting arrangement, the guide extends beyond the fifth fitting, wherein a part of the support portion is located between the guide and the fifth fitting.

In Fig. 1 ist in einem Horizontalschnitt die Gießanordnung in einer ersten Ausführungsform wiedergegeben. Die Gießform 2 dieser Gießanordnung weist in ihrem Inneren zwei Gießkavitäten 1A, 1B, also Hohlräume zum Gießformen jeweils eines Gussteils, auf. Figur 1 gibt die Situation nach dem Guss wieder. Daher sind die zwei Hohlräume 1A, 1B bereits vollständig mit flüssigem Metall gefüllt, z. B. einer Schmelze aus einer Aluminiumlegierung, einer Magnesiumlegierung oder einer Zinklegierung.In Fig. 1 is shown in a horizontal section, the casting assembly in a first embodiment. The casting mold 2 of this casting arrangement has in its interior two casting cavities 1A, 1B, ie cavities for the casting molding of a casting in each case. FIG. 1 reflects the situation after the casting. Therefore, the two cavities 1A, 1B are already completely filled with liquid metal, z. As a melt of an aluminum alloy, a magnesium alloy or a zinc alloy.

Bei der Gießanordnung nach Fig. 1 handelt es sich um ein sogenanntes 3-Plattenwerkzeug mit Platten 8, 4 und 3. Zum Einfüllen der Metallschmelze dient eine in einer festen Platte 8 der Gießanordnung ausgebildete, zentrale Gießkammer 5, von der ein erster Kanal 5A durch eine Grundplatte 4 der Gießform hindurch zu dem ersten Hohlraum 1A, und ein zweiter Kanal 5B durch die Grundplatte 4 hindurch zu dem zweiten Hohlraum 1B führt. Die Kanäle 5A, 5B sind in Fig. 1 gestrichelt wiedergegeben, und ebenso in Fig. 3 in Bezug auf die zweite Ausführungsform. In den übrigen Figuren 2 und 4 bis 7 sind die Kanäle nicht wiedergegeben.In the casting arrangement according to Fig. 1 is a so-called 3-plate tool with plates 8, 4 and 3. For filling the molten metal is formed in a fixed plate 8 of the casting assembly, central casting chamber 5, from which a first channel 5A through a base plate 4 of the mold through the first cavity 1A, and a second channel 5B leads through the base plate 4 to the second cavity 1B. The channels 5A, 5B are in Fig. 1 dashed lines, and also in Fig. 3 with respect to the second embodiment. In the rest Figures 2 and 4 to 7 the channels are not playing.

Nachdem die beiden Gussteile ausreichend abgekühlt sind, wird die Gießform 2 schrittweise geöffnet und damit die Gussteile entformt, was in einzelnen Schritten erfolgt. In Fig. 1 ist hierzu eine erste, horizontale Entformungsrichtung D1 und eine zu der ersten Entformungsrichtung unterschiedliche, zweite Entformungsrichtung D2 eingezeichnet. Vorzugsweise ist die zweite Entformungsrichtung D2 quer bzw. rechtwinklig zu der ersten Entformungsrichtung D1.After the two castings have cooled sufficiently, the mold 2 is opened gradually and thus the castings removed from the mold, which takes place in individual steps. In Fig. 1 For this purpose, a first horizontal Entformungsrichtung D1 and a different from the first Entformungsrichtung, second Entformungsrichtung D2 located. Preferably, the second Entformungsrichtung D2 is transverse or perpendicular to the first Entformungsrichtung D1.

Bestandteil der Gießform ist eine quer zu der ersten Entformungsrichtung D1 angeordnete, erste Grundplatte 3, gegen die erste, die Gestalt der Gießkavitäten 1A, 1B bestimmende Formstücke 11A, 11B in Entformungsrichtung D1 abgestützt sind. Eine zweite Grundplatte 4 dient hier als Zwischenplatte der Gießanordnung und ist gegen die feste Platte 8 abgestützt.Part of the casting mold is a first base plate 3, which is arranged transversely to the first demolding direction D1, against which first shaped pieces 11A, 11B, which determine the shape of the casting cavities 1A, 1B, are supported in the removal direction D1. A second base plate 4 serves as an intermediate plate of the casting arrangement and is supported against the fixed plate 8.

Gegen die zweite Grundplatte 4 (Zwischenplatte) sind zweite, die Gestalt der Gießkavitäten 1A, 1B bestimmende Formstücke 12A, 12B in Entformungsrichtung D1 abgestützt.Against the second base plate 4 (intermediate plate) are second, the shape of the casting cavities 1A, 1B defining mold pieces 12A, 12B supported in Entformungsrichtung D1.

Bestandteil der Gießform 2 sind ferner Seitenteile 6, 7, die zwischen den Grundplatten 3, 4 angeordnet sind. Dabei ist an dem ersten Seitenteil 6 ein die Gestalt der ersten Gießkavität 1A bestimmendes, drittes Formstück 13, abgestützt. An dem zweiten Seitenteil 7 ist ein die Gestalt der zweiten Gießkavität 1B bestimmendes, viertes Formstück 14, abgestützt.Part of the mold 2 are also side parts 6, 7, which are arranged between the base plates 3, 4. In this case, on the first side part 6 a the shape of the first casting cavity 1A determining, third fitting 13, supported. On the second side part 7, a shape of the second casting cavity 1B determining, fourth fitting 14, supported.

Die Seitenteile 6, 7 sind an der ersten Grundplatte 3 in der zweiten Entformungsrichtung D2 beweglich geführt, um so nach dem Erstarren der Schmelze die Gießform in seitlicher Richtung, d. h. in Richtung der zweiten Entformungsrichtung D2, öffnen zu können. An den Seitenteilen 6, 7 sind jeweils die Form des Gusses bestimmende Formstücke 13 bzw. 14 befestigt.The side parts 6, 7 are movably guided on the first base plate 3 in the second demolding direction D2, so that after the solidification of the melt, the casting mold in the lateral direction, d. H. in the direction of the second Entformungsrichtung D2, to be able to open. At the side parts 6, 7 respectively the shape of the casting determining fittings 13 and 14 are attached.

Zentraler Bestandteil der Gießanordnung ist ein die Form beider Gießkavitäten 1A, 1B bestimmendes, fünftes Formstück 15. Das fünfte Formstück 15 ist so an der ersten Grundplatte 3 befestigt, dass es sich zwischen den beiden Gießkavitäten 1A, 1B befindet, und es zugleich die Form beider Gießkavitäten 1A, 1B bestimmt.The central component of the casting arrangement is a fifth fitting 15 which determines the shape of both casting cavities 1A, 1B. The fifth fitting 15 is fastened to the first base plate 3 so that it is located between the two casting cavities 1A, 1B and at the same time has the shape of both Casting cavities 1A, 1B determined.

Die Seitenteile 6, 7 mit den Formstücken 13, 14 sind in der zweiten Entformungsrichtung D2 längs der ersten Grundplatte 3 beweglich geführt, was der Vergleich des Entformungsschritts nach Fig. 4 zu dem Entformungsschritt nach Fig. 5 zeigt.The side parts 6, 7 with the fittings 13, 14 are movably guided in the second removal direction D2 along the first base plate 3, which is the comparison of the demolding step after Fig. 4 to the demolding step Fig. 5 shows.

Die ersten Formstücke 11A, 11B sind jeweils an Führungen 31A, 31B abgestützt, die an der ersten Grundplatte 3 ausgebildet sind und sich quer zur Richtung der ersten Entformungsrichtung D1 erstrecken. Entlang dieser Führungen 31A, 31B sind die ersten Formstücke 11A, 11B daher längsbeweglich, wie der Vergleich der Fig. 5 mit der Fig. 6 zeigt.The first mold pieces 11A, 11B are respectively supported on guides 31A, 31B formed on the first base plate 3 and transverse to the direction of the first Entformungsrichtung D1 extend. Along these guides 31A, 31B, the first mold pieces 11A, 11B are therefore longitudinally movable, as the comparison of Fig. 5 with the Fig. 6 shows.

Vorzugsweise ist die linke Führung 31A gleichgerichtet und fluchtend zu der rechten Führung 31B angeordnet. Anschläge 35A, 35B an der unteren Grundplatte 3 begrenzen die Bewegungsmöglichkeit der ersten Formstücke 11A, 11B in einer Richtung aufeinander zu.Preferably, the left guide 31A is rectified and disposed in alignment with the right guide 31B. Stops 35A, 35B on the lower base plate 3 limit the possibility of movement of the first shaped pieces 11A, 11B in a direction towards each other.

Die ersten Formstücke 11A, 11B bestehen jeweils aus einem die Gestalt der jeweiligen Gießkavität 1A, 1B mitbestimmenden Formabschnitt 33, und aus einem Trägerabschnitt 32. Nur der Trägerabschnitt 32 ist an der jeweiligen Führung 31A, 31B gleitbeweglich abgestützt. Der Formabschnitt 33 hingegen bestimmt den Formraum der Gießkavität.The first shaped pieces 11A, 11B each consist of a shape portion 33 co-determining the shape of the respective casting cavity 1A, 1B, and a support portion 32. Only the support portion 32 is slidably supported on the respective guide 31A, 31B. The mold portion 33, however, determines the mold cavity of the casting cavity.

Insbesondere aus dem Entformungsschritt nach Fig. 6 ist erkennbar, dass sich die Führung 31A, 31B bis hinter die Rückseite des fünften Formstücks 15 erstreckt, indem sich ein Teil des längs der unteren Grundplatte 3 beweglichen Trägerabschnitts 32 zwischen der Führung 31A, 31B und dem fünften Formstück 15 befindet.In particular from the demolding step Fig. 6 It can be seen that the guide 31A, 31B extends beyond the back of the fifth fitting 15 by having a portion of the support portion 32 movable along the lower base plate 3 between the guide 31A, 31B and the fifth fitting 15.

Bei der in den Figuren 2 bis 7 wiedergegebenen Gießanordnung handelt es sich um ein sogenanntes 2-Plattenwerkzeug. Zum Einfüllen der Metallschmelze ist hier die zweite Grundplatte 4 mit zwei, für die beiden Gießkavitäten 1A, 1B parallel und gleichzeitig arbeitenden Gießkolben sowie zwei Gießkammern versehen.In the in the FIGS. 2 to 7 reproduced casting arrangement is a so-called 2-plate tool. For filling the molten metal, the second base plate 4 is here provided with two casting pistons, which operate in parallel and simultaneously for the two casting cavities 1A, 1B, and two casting chambers.

Fig. 2 gibt die Gießanordnung vor Beginn des Einfüllens der Metallschmelze wieder. Die beiden ersten Formstücke 11A, 11B nehmen ihre maximal aufeinander zu bewegbare Stellung ein. Im Übrigen sind sämtliche Teile der Gießform geschlossen. Fig. 2 is the casting assembly before the beginning of filling the molten metal again. The two first shaped pieces 11A, 11B assume their maximum position that can be moved towards one another. Incidentally, all parts of the mold are closed.

Die Fig. 3 gibt, ebenso wie Fig. 1, die Situation nach dem Einfüllen und dem ausreichenden Erstarren der Schmelze wieder.The Fig. 3 there as well Fig. 1 , the situation after filling and sufficient solidification of the melt again.

Die Fig. 4 zeigt in einem ersten Entformungsschritt das Trennen der beweglichen ersten Grundplatte 3 von der zweiten Grundplatte 4. Da die zweiten Formstücke 12A, 12B an der zweiten Grundplatte 4 befestigt sind, lösen sich diese von den schwarz dargestellten Gussteilen. Dieser erste Entformungsschritt erfolgt durch Bewegen der ersten Grundplatte 3 in der ersten Entformungsrichtung D1.The Fig. 4 shows in a first Entformungsschritt the separation of the movable first base plate 3 of the second base plate 4. Since the second fittings 12 A, 12 B are attached to the second base plate 4, these detach from the black castings. This first demolding step takes place by moving the first base plate 3 in the first removal direction D1.

Fig. 5 zeigt den zweiten Entformungsschritt. Hierbei werden die beiden Seitenteile 6, 7 jeweils seitlich nach außen bewegt, was in der zweiten Entformungsrichtung D2 erfolgt. Dadurch geben die daran befestigten dritten und vierten Formstücke 13, 14 das jeweilige Gussteil frei, was vorzugsweise gleichzeitig erfolgt. Fig. 5 shows the second demolding step. Here, the two side parts 6, 7 are each moved laterally outwards, which takes place in the second Entformungsrichtung D2. Thereby give the attached third and fourth fittings 13, 14, the respective casting free, which is preferably done simultaneously.

In Fig. 6 ist der dritte Entformungsschritt wiedergegeben. Dieser erfolgt, indem das eine erste Formstück 11A quer zur ersten Entformungsrichtung D1 nach außen bewegt wird, und ebenso, aber entgegengesetzt, das andere erste Formstück 11B quer zur ersten Entformungsrichtung D1 nach außen bewegt wird, wobei sich die beiden ersten Formstücke 11A, 11B voneinander entfernen. Dabei werden sie entlang der Führung 31A bzw. 31B geführt, die an der ersten Grundplatte 3 ausgebildet ist. Die Fig. 6 zeigt die Situation, in der die ersten Formstücke 11A, 11B ihre äußere Position erreicht haben. Sie nehmen mit ihren Formabschnitten 33 das jeweilige Gussteil mit, wodurch sich dieses von dem unbeweglich an der ersten Grundplatte 3 angeordneten, zentralen Formstück 15 löst.In Fig. 6 the third demolding step is reproduced. This is done by moving one of the first mold pieces 11A outwards transversely of the first mold removal direction D1, and also, but oppositely, moving the other first mold piece 11B outwards transversely of the first mold removal direction D1, with the first two mold pieces 11A, 11B facing away from each other remove. They are guided along the guide 31A and 31B, which is formed on the first base plate 3. The Fig. 6 shows the situation in which the first mold pieces 11A, 11B have reached their outer position. They take with their mold sections 33 with the respective casting, causing it from the immovably arranged on the first base plate 3, central mold piece 15 dissolves.

In Fig. 7 schließlich ist das vorzugsweise maschinelle Abnehmen der Gussteile von den Formabschnitten 33 der ersten Formstücke 11A, 11B wiedergegeben. Dieses Abnehmen erfolgt in der ersten Entformungsrichtung D1.In Fig. 7 Finally, the preferably mechanical removal of the castings from the mold sections 33 of the first mold pieces 11A, 11B is reproduced. This removal takes place in the first removal direction D1.
