Description
Die Erfindung bezieht sich auf ein Gießverfahren und insbesondere ein Schwerkraft- oder Niederdruckgussverfahren für metallische Schmelzen, bei dem die Schmelzefüllung des Gießwerkzeugs ein Insbesondere partikelförmiges, mit der Schmelze kompatibles Zusatzmaterial enthält, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a casting method and in particular a gravity or low pressure casting method for metallic melts, in which the melt filling of the casting tool contains a particular particulate, compatible with the melt additive material, according to the preamble of
Bei den aus der
Aufgabe der Erfindung ist es, ein Gießverfahren der eingangs genannten Art so auszubilden, dass sich mit deutlich verkürzten Taktzeiten und geringem Fertigungsmittelaufwand qualitativ hochwertige Gussteile herstellen lassen.The object of the invention is to provide a casting method of the type mentioned in such a way that can produce high-quality castings with significantly reduced cycle times and low production cost.
Diese Aufgabe wird erfindungsgemäß durch das im Patentanspruch 1 gekennzeichnete Verfahren gelöst.This object is achieved by the characterized in
Erfindungsgemäß wird durch den inneren Kühleffekt der von der Schmelzefüllung umschlossenen Kühlkörper die Zeitspanne bis zur Entformbarkeit des Gussteils signifikant in einem proportional zum Kühlkörperanteil ansteigenden Ausmaß verkürzt, ohne dass es einer leistungsstarken und dementsprechend aufwändigen Außenkühlung des Gießwerkzeugs bedarf, und zugleich der Temperaturverlauf in der kritischen Abkühlphase bis zur Verfestigung des Gussteils soweit vergleichmäßigt, dass der Entstehung von Wärmespannungen oder Lunkerbildungen wirksam begegnet wird.According to the invention is shortened by the internal cooling effect of the melt-enclosed heat sink, the time to demolding of the casting significantly in proportion to the heat sink proportion increasing extent, without the need for a powerful and therefore complex external cooling of the casting mold, and at the same time the temperature profile in the critical cooling phase until the solidification of the casting is evened out so far that the formation of thermal stresses or voids is effectively counteracted.
In besonders bevorzugter Ausgestaltung der Erfindung werden die zunächst festen Kühlkörper seitens der Schmelzefüllung in der Formkavität aufgeschmolzen und die Schmelztemperatur der Kühlkörper wird unter derjenigen der Schmelzefüllung gehalten, wodurch sich die spezifische Kühlkapazität der Kühlkörper wesentlich erhöht und sichergestellt wird, dass die Schmelzwärme der Kühlkörper erst nach außen abgegeben wird, wenn das Gussteil bereits erstarrt ist und entformt werden kann.In a particularly preferred embodiment of the invention, the first solid heat sink melted by the melt filling in the mold cavity and the melting temperature of the heat sink is kept below that of the melt filling, whereby the specific cooling capacity of the heat sink significantly increased and ensures that the heat of fusion of the heat sink only after is discharged outside when the casting is already solidified and can be removed from the mold.
Da der größte Teil des Wärmeinhalts der Schmelzefüllung in der Erstarrungsphase freigesetzt wird, wird die Kühlwirkung der Kühlkörper durch eine entsprechende Wahl der Schmelztemperatur, der Wärmeleitfähigkeit und der Partikelgröße vorzugsweise so abgestimmt, dass die Kühlkörper zunächst noch im festen Zustand verbleiben oder nur randseitig angeschmolzen werden und erst in der Erstarrungsphase der Schmelzefüllung vollständig in den schmelzflüssigen Zustand übergehen. In Verbindung mit einer bevorzugt homogenen Verteilung der Kühlkörper ergibt sich hieraus der gießtechnische Vorteil, dass sich die Erstarrungsfront der Schmelzefüllung im gesamten Füllvolumen sehr rasch ausbreitet und dadurch Gussfehler, die sonst bei einer nur langsam fortschreitenden Verfestigung der Formfüllung entstehen, wirksam unterbunden werden. In dieser Hinsicht ist es natürlich wünschenswert, die Schmelzwärme der Kühlkörperzumischung, bezogen auf diejenige der Schmelzefüllung, möglichst groß zu wählen, begrenzt allerdings durch die Verträglichkeit des Kühlkörpermaterials mit den angeforderten Materialeigenschaften des Gussteils. Unter dem Gesichtspunkt der Materialverträglichkeit werden als Kühlkörper zweckmäßigerweise solche mit einer artgleichen Materialzusammensetzung wie die Schmelzefüllung zugemischt und im bevorzugten Fall einer Aluminiumschmelze zweckmäßigerweise niedriger schmelzende Legierungszusätze, wie z. B. Magnesium, und auch Schrottpartikel aus einer niedriger schmelzenden Aluminiumlegierung.Since the majority of the heat content of the melt filling is released in the solidification phase, the cooling effect of the heat sink is preferably adjusted by an appropriate choice of melting temperature, thermal conductivity and particle size so that the heat sink initially remain in the solid state or are melted only at the edge and completely in the molten state only in the solidification phase of the melt filling. In conjunction with a preferably homogeneous distribution of the heat sink, this results in the casting technology advantage that the solidification front of the melt filling spreads very rapidly in the entire filling volume and thereby casting defects that would otherwise occur in a slowly progressive solidification of the mold filling, effectively prevented. In this regard, it is of course desirable to choose the heat of fusion of the heat sink admixture, based on that of the melt filling, as large as possible, but limited by the compatibility of the heat sink material with the required material properties of the casting. From the point of view of material compatibility are preferably added as a heat sink with a similar material composition as the melt filling and in the preferred case of an aluminum melt expediently lower melting alloying additives such. As magnesium, and also scrap particles from a lower melting aluminum alloy.
Nach einer weiterhin besonders bevorzugten Ausführungsform der Erfindung werden die Kühlkörper der Schmelze in einer zeitlich unterschiedlichen Dosierung mit einem höheren Kühlkörperanteil in dem die stärker zu kühlenden Bereiche der Formkavität ausfüllenden Schmelzevolumen zugegeben, um so die Abkühlung der Schmelzefüllung weiter zu vergleichmäßigen. Schließlich müssen die Kühlkörper der Schmelze nicht unbedingt beim Befüllen des Gießwerkzeugs zugemischt werden, sondern können auch vor dem Guss in die Formkavität eingebracht werden.According to a further particularly preferred embodiment of the invention, the heat sink of the melt are added in a time varying dosage with a higher heat sink portion in the more strongly cooled areas of the mold cavity filling melt volume, so as to further homogenize the cooling of the melt filling. Finally, the heat sinks of the melt do not necessarily have to be mixed during filling of the casting tool, but can also be introduced into the mold cavity before casting.
Die Erfindung wird nunmehr an Hand eines Ausführungsbeispiels in Verbindung mit den Zeichnungen näher erläutert. Es zeigen in stark schematisierter Darstellung:The invention will now be explained in more detail with reference to an embodiment in conjunction with the drawings.
