Description

Die Erfindung betrifft eine Gießform, umfassend Außenformteile und darin eingelegte Formstoffkerne, die miteinander einen Formhohlraum bilden. Die Außenformteile können Teile einer Dauergießform und/oder Formstoffteile/Außenkerne sein.The invention relates to a casting mold, comprising outer molded parts and mold cores inserted therein, which together form a mold cavity form. The outer molded parts can be parts of a permanent mold and / or molded parts / outer cores.

Zur Darstellung komplizierter Gußstücke, beispielsweise von Zylinderköpfen, werden notwendigerweise Formstoffkerne in die Außenformteile eingelegt. Hierbei ist es bereits bekannt, auch Außenkerne aus Formstoff zu verwenden, so daß wesentliche Teile der Gußstückaußenflächen nicht von einer metallischen Kokillenwand, sondern von Außenkernen aus Formstoff abgebildet werden. Dies eignet sich besonders für das Gießen von Aluminium- und Magnesiumlegierungen.To represent complicated castings, for example from Cylinder heads are necessarily molded material cores in the External molded parts inserted. Here it is already known, too To use outer cores made of molded material, so that essential parts the outer surface of the casting is not covered by a metal mold wall, but are represented by molded plastic outer cores. This is particularly suitable for the casting of aluminum and Magnesium alloys.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Gießform der genannten Art bereitzustellen, die für komplizierte Gußstücke verwendbar ist und die insbesondere zum Drehgießen geeignet ist.The present invention has for its object a To provide casting mold of the type mentioned for complicated Castings can be used and in particular for rotary casting suitable is.

Die Lösung hierfür besteht darin, daß Innenkerne aus Formstoff in mehreren Lagen aufeinandergeschichtet sind und in durchgehendem Kraftfluß zwischen Außenformteilen und einem abschließenden Deckkern aus Formstoff eingespannt sind, wobei der Formhohlraum von Oberflächen der Außenformteile und Oberflächen der Innenkerne und des Deckkerns gebildet wird. Hiermit wird erfindungsgemäß auf darüberhinausgehende Mittel zur Fixierung der Formstoffkerne in den Außenformkernen und zwischen den Formstoffkernen untereinander verzichtet. Der Aufbau in mehreren Schichten erlaubt eine komplizierte Formgebung. Die Verwendung des abschließenden Deckkerns aus Formstoff erlaubt ein Andocken eines Gießbehälters (Kontaktgießen) und schafft damit die Voraussetzung für ein Drehgießverfahren. Der Deckkern weist hierzu vorzugsweise zumindest eine Eingußöffnung und zumindest eine Gasaustrittsöffnung auf.The solution to this is that the inner cores are made of molded material are stacked in several layers and in a continuous Power flow between the outer molded parts and a final one Cover core made of molded material are clamped, the mold cavity of surfaces of the outer molded parts and surfaces of the inner cores and the cover core is formed. This is according to the invention on other means to fix the molding cores in the outer mold cores and between the mold material cores with each other waived. The construction in several layers allowed a complicated shape. The use of the final Molded cover core allows a casting container to be docked (Contact casting) and thus creates the prerequisite for one Rotary casting process. For this purpose, the cover core preferably has at least a gate and at least one gas outlet on.

In weiterführender Form ist vorgesehen, daß die Teile der Gießform eine Grundplatte und mehrere gegenüber dieser bewegliche Seitenteile umfassen. Hierbei können die Seitenteile insbesondere zwei gegenüber der Grundplatte vom Formhohlraum entgegengesetzt nach außen wegschiebbare Längsseitenteile umfassen und/oder zumindest ein gegenüber der Grundplatte vom Formhohlraum nach außen wegschwenkbares Stirnseitenteil umfassen. Durch diese Maßnahme ist ein problemloser Aufbau der in mehreren Schichten aufgestapelten Innenkerne möglich. Die Seitenteile können hierbei an den Innenseiten Formvorsprünge aufweisen, die einzelne der Innenkerne zusätzlich gegenüber der Grundplatte festhalten. Zur Festlegung des Deckkernes können an der Grundplatte oder an zumindest zwei Seitenteilen verschiebbare Riegel oder schwenkbare Klauen angeordnet sein, die das Paket der Formstoffkerne innerhalb der Gießform in einer Weise sichern, daß auch beim Drehen der Gießform Verschiebungen zwischen den Innenkernen ausgeschlossen sind.In a further form it is provided that the parts of the mold one base plate and several movable with respect to this Include side panels. Here, the side parts in particular two opposite the base plate from the mold cavity include outwardly sliding longitudinal side parts and / or at least one opposite the base plate from the mold cavity Front part that can be swung outward. By this measure is a problem-free construction of several Layers of stacked inner cores possible. The side parts can have molded projections on the inside that some of the inner cores also opposite the base plate hold tight. You can use the base plate to fix the cover core or slidable bars on at least two side parts or pivoting claws can be arranged, which the package of the molding cores secure within the mold in such a way that Even when turning the mold, there are shifts between the inner cores excluded are.

In einer besonders günstigen Art der Verwendung einer erfindungsgemäßen Gießform wird diese zunächst auf der Grundplatte stapelnd aufgebaut, dann um 180° um eine horizontale Achse gedreht, so daß der Deckkern, der eine Eingußöffnung aufweist, nach unten zu liegen kommt. An den Deckkern wird sodann ein Gießbehälter, der mit Schmelze für einen Gießvorgang gefüllt ist, angedockt. Beim erneuten Drehen um 180° um die horizontale Achse fließt die Schmelze über die Eingußöffnung im Deckkern in den Formhohlraum. Anschließend wird der Schmelzebehälter entfernt und es kommt zur Erstarrung des Gußteils, wonach die Gießform entformt werden kann. Die Gießform wird vorzugsweise jeweils um eine zu ihrer Längserstreckung parallele Achse gedreht.In a particularly favorable way of using an inventive This mold is first placed on the base plate stacked, then 180 ° around a horizontal axis rotated so that the cover core, which has a pouring opening, comes to lie down. Then on the cover core Pouring container that is filled with melt for a pouring operation is docked. When rotating again by 180 ° around the horizontal The melt flows in through the pouring opening in the core the mold cavity. The melt container is then removed and the casting solidifies, after which the Mold can be removed from the mold. The mold is preferred each rotated about an axis parallel to their longitudinal extent.

Die Grundplatte ist als Dauerformteil aus Metall ausgebildet; die Außenformteile können ebenfalls Dauerformteile sein, die mit der Grundplatte mechanisch verbunden sind, oder Formstoffteile sein, die mit mechanischen Spannmitteln von den Seiten und von oben auf der Grundplatte zusammen und aufgespannt werden.The base plate is designed as a permanent molded part made of metal; the outer molded parts can also be permanent molded parts with the base plate are mechanically connected, or molded parts be with mechanical clamping devices from the sides and from together on the base plate and clamped.

Die Figuren 1 und 2 werden weitgehend gemeinsam beschrieben. Eine erfindungsgemäße Gießform 11 umfaßt eine mehrteilige Grundplatte 12, Seitenteile 13, 14, jeweils als Dauerformteile, eine Mehrzahl von Innenkernen 15, die in mehreren Schichten übereinander auf der Grundplatte 12 aufgebaut sind, sowie einen Deckkern 16, jeweils aus Formstoff bestehend. Die mehreren Innenkerne 15 sind in durchgehendem Kraftfluß zwischen der Grundplatte 12 und dem Deckkern 16 eingespannt. An den Seitenteilen 13, 14 sind Formvorsprünge 17, 18 erkennbar, die einzelne der Innenkerne 15 zusätzlich gegen die Grundplatte 12 halten. Die Seitenteile 13, 14 sind durch Stellzylinder 19, 20 gegenüber der Grundplatte 12 entgegengesetzt gerichtet verschiebbar. Hierbei sind sie gegenüber der dargestellten Position voneinander entfernbar. Danach kann der stapelnde Aufbau der Innenkerne 15 auf der Grundplatte 12 erfolgen. Danach sind die Seitenteile 13, 14, wie durch entgegengesetzt gerichtete Pfeile angedeutet, wieder schließbar, um erneut die dargestellte Position zu erreichen. Danach wird der Deckkern 16 aufgelegt. Auf den Seitenteilen 13, 14 sind Riegel 21, 22 angeordnet, die zur Montage gegenüber den Seitenteilen 13, 14 zurückgeschoben werden können und nach dem Auflegen des Deckkerns 16 in die dargestellte Position vorgeschoben werden können, in der sie den Deckkern 16 gegenüber den Innenkernen 15 und den Seitenteilen 13, 14 halten. In der Grundplatte 12 sind Ausstoßer 23, 24 erkennbar, die zum Entformen mittels eines Stellzylinders 25 betätigbar sind. Die Grundplatte 12 und damit die gesamte Gießform 11 ist um eine horizontale senkrecht zur Zeichnungsebene liegende Achse 27 drehbar. Dies gilt in gleicher Weise für eine Säule 27, auf der ein Schwenkarm 28 gelagert ist, der einen Gießbehälter 29 trägt, der mit einem Stellzylinder 30 parallel zur Säule 27 auf dem Schwenkarm 28 verschoben werden kann.Figures 1 and 2 are largely described together. A casting mold 11 according to the invention comprises a multi-part base plate 12, side parts 13, 14, each as permanent molded parts, one A plurality of inner cores 15, which are stacked in several layers are built on the base plate 12, and a cover core 16, each consisting of molding material. The multiple inner cores 15 are in a continuous flow of force between the base plate 12 and the cover core 16 clamped. On the side parts 13, 14 form projections 17, 18 can be seen, the individual of the Hold the inner cores 15 against the base plate 12. The Side parts 13, 14 are by actuating cylinders 19, 20 opposite the Base plate 12 can be moved in the opposite direction. Here they can be removed from each other in relation to the position shown. The stacking structure of the inner cores 15 can then be opened the base plate 12. Then the side parts 13, 14, as indicated by opposite arrows, again lockable to reach the position shown again. The cover core 16 is then placed on top. On the side parts 13, 14 bars 21, 22 are arranged, which are opposite to the mounting Side parts 13, 14 can be pushed back and after Placing the cover core 16 advanced into the position shown can be in which they cover the core 16 against the Hold inner cores 15 and the side parts 13, 14. In the base plate 12 ejectors 23, 24 can be seen, which are used for demolding can be actuated by means of an actuating cylinder 25. The base plate 12 and thus the entire mold 11 is horizontal Axis 27 lying perpendicular to the plane of the drawing. This applies in the same way to a column 27 on which a swivel arm 28 is mounted, which carries a casting container 29, which with a Actuating cylinder 30 parallel to the column 27 on the swivel arm 28 can be moved.

In Figur 1 ist die fertig aufgebaute Gießform 11 in ihrer Position unmittelbar nach dem stapelnden Aufbau gezeigt. Der Gießbehälter 29 hängt überkopf, ist über den Stellzylinder 30 von der Gießform 11 entfernt und durch den Schwenkarm 28 auf der Säule 27 um 90° gegenüber der Gießform verschwenkt.In Figure 1, the fully assembled mold 11 is in its position shown immediately after stacking construction. The pouring can 29 hangs overhead, is on the actuating cylinder 30 of the Removed mold 11 and through the pivot arm 28 on the column 27 pivoted 90 ° relative to the mold.

In Figur 2 ist die Gießform 11 mit Säule 27 und Gießbehälter 29 um 180° um die Achse 26 gedreht dargestellt. Der Gießbehälter 29 befindet sich noch in gleicher Relativposition zur Gießform 11 wie in Figur 1, ist jedoch jetzt nach oben offen und wird mittels eines Dosierlöffels 31 gerade mit Schmelze 32 für einen Gießvorgang befüllt. In FIG. 2, the mold 11 with the column 27 and the casting container 29 shown rotated by 180 ° around the axis 26. The casting tank 29 is still in the same position relative to the mold 11 as in Figure 1, but is now open at the top and is by means of a dosing spoon 31 just with melt 32 for one Pouring process filled.

Nach dem Befüllen des Gießbehälters 29 wird der Schwenkarm 28 um 90° relativ zur Säule 27 geschwenkt, so daß der Gießbehälter 29 unter der Gießform 11 vor der Säule 27 zu liegen kommt. Sodann wird der Gießbehälter 29 mittels des Zylinders 30 gegen die Gießform 11 gehoben, bis der Gießbehälter 29 abdichtend an dem Deckkern 16 anliegt. In der damit erreichten Position wird die Gießform 11 mit angedocktem Gießbehälter 29 wiederum um die Achse 26 um 180° weitergedreht. Die auf den Formhohlraum abgemessene Schmelze 32 fließt dabei über den Einguß 33 in den Formhohlraum, wobei Gas aus dem Gasaustritt 34 in den Gießbehälter 29 entweichen kann. Nach Beendigung des Drehvorganges und damit des Gießvorganges, in der wieder die Stellung der Gießform 11 nach Figur 1 erreicht ist, wird der Gießbehälter 29 mit dem Stellzylinder 30 von der Gießform 11 abgehoben und mittels des Schwenkarms 28 in die in Figur 1 dargestellte Position zurückgedreht. Nach dem Erstarren kann das Entformen durch Zurückziehen der Seitenteile 13, 14 und Betätigen der Ausstoßer 23, 24 erfolgen.After filling the casting container 29, the swivel arm 28 is around 90 ° pivoted relative to the column 27 so that the casting container 29th comes to rest under the mold 11 in front of the column 27. Then is the casting tank 29 by means of the cylinder 30 against the Casting mold 11 lifted until the casting container 29 seals against the Cover core 16 abuts. In the position reached with it, the Casting mold 11 with docked casting container 29 in turn around the Axis 26 turned through 180 °. The one measured on the mold cavity Melt 32 flows through the gate 33 into the mold cavity, whereby gas from the gas outlet 34 into the casting container 29 can escape. After the turning process and thus the casting process, in which the position of the mold 11 1 is reached, the casting container 29 with the Actuating cylinder 30 lifted from the mold 11 and by means of Swivel arm 28 rotated back into the position shown in Figure 1. After solidification, the demolding can be done by pulling back the side parts 13, 14 and actuation of the ejectors 23, 24 respectively.

Die Seitenteile 13, 14 könnten auch aus Formstoff bestehen, wobei anstelle der Riegel 21, 22 dann mit der Grundplatte verbundene Niederhalter treten würden. The side parts 13, 14 could also consist of molding material, where instead of the latch 21, 22 then connected to the base plate Hold down.
