Abstract
Vorgeschlagen wird eine Vorrichtung zum Gießen von Gußeisen in einer Kokille mit einer mehrteiligen metallischen Kokille 1, die eine Sandform 3 umschließt, in deren Hohlraum 4 das geschmolzene Gußeisen eingefüllt wird. Zur Verbesserung nicht nur der Kühlung, sondern insbesondere auch der Steuerbarkeit der Kühlung ist erfindungsgemäß zwischen der Innenwand der Kokille und der Außenwand der Sandform wenigstens ein kühlmitteldurchströmter Raum 2 gebildet, der vorzugsweise die Form wenigstens eines zwischen einem Kühlmitteleintritt 5 und -austritt 8 verlaufenden Kanals hat und dabei jeweils etwa zur Hälfte gebildet ist durch eine rinnenartige Vertiefung der Innenwand der Kokille 1 und eine gegenüberliegende rinnenartige Vertiefung in der Außenwand der Sandform 3. Die verbesserte Kühlung und Lenkbarkeit der Erstarrung des Gußteils ermöglicht die Erzielung optimaler, reproduzierbarer Material- und Gefügeeigenschaften.Proposed is a device for casting cast iron in a mold with a multi-part metallic mold 1, which encloses a sand mold 3, in the cavity 4, the molten cast iron is filled. In order to improve not only the cooling, but in particular the controllability of cooling, at least one coolant-flowed space 2 is formed between the inner wall of the mold and the outer wall of the sand mold, which preferably has the shape of at least one channel extending between a coolant inlet 5 and outlet 8 and in each case about half formed by a groove-like depression of the inner wall of the mold 1 and an opposite groove-like depression in the outer wall of the sand mold 3. The improved cooling and steerability of the solidification of the casting enables the achievement of optimal, reproducible material and structural properties.
Description
Die vorliegende Erfindung betrifft eine Vorrichtung zum Gießen von Gußeisen in einer Kokille mit einer mehrteiligen metallischen Kokille, die eine Sandform umschließt, in deren Hohlraum das geschmolzene Gußeisen eingefüllt wird. Eine solche Vorrichtung ist aus
Bei dieser bekannten Vorrichtung soll eine gesteuerte Abkühlung des Werkstoffs nach Füllung der Sandform dadurch erreicht werden, daß die mehreren Kokillenteile kühlmitteldurchströmte Hohlräume aufweisen und diese entsprechend den gewünschten Kühlbedingungen vom Kühlmittel beaufschlagt werden.In this known device, a controlled cooling of the material after filling the sand mold is to be achieved in that the plurality of mold parts have coolant flowed through cavities and these are acted upon by the coolant according to the desired cooling conditions.
Eine vollkommene Erreichung des Ziels der gesteuerten Abkühlung ist jedoch schwer erreichbar, da der Wärmeabtransport hier erst über die zwischen Gußteil und Kokilleninnenseite gelegene Sandformwand und dann auch noch über die Innenwände der Kokillenteile stattfindet.A complete achievement of the goal of the controlled cooling is difficult to achieve, since the heat dissipation takes place here only on the between the casting and Kokilleninnenseite located sand mold wall and then also on the inner walls of Kokillenteile.
Aufgabe der Erfindung ist die Erzielung nicht nur einer besseren Kühlung sondern auch einer besseren Steuerbarkeit dieser Kühlung. Die auf diese Weise gelenkte Erstarrung des Gußteils soll die Erzielung optimaler, reproduzierbarer Material- und Gefügeeigenschaften im Gußteil/Bauteil ermöglichen. Schließlich sollen durch die verbesserte Kühlung auch kürzere Taktzeiten und damit erhöhte Leistung der Fertigung erzielt werden.The object of the invention is to achieve not only a better cooling but also a better controllability of this cooling. The controlled in this way solidification of the casting should enable the achievement of optimal, reproducible material and structural properties in the casting / component. Finally, to be achieved by the improved cooling and shorter cycle times and thus increased performance of the production.
Die Lösung der gestellten Aufgabe ergibt sich aus den Patentansprüchen.The solution of the problem arises from the claims.
Die Erfindung wird nachfolgend durch die Beschreibung eines Ausführungsbeispiels anhand der beigegebenen Zeichnung weiter erläutert werden. Diese zeigt schnittbildlich eine Gießvorrichtung der vorgeschlagenen Zusammenstellung.The invention will be further explained by the description of an embodiment with reference to the attached drawing. This shows a sectional view of a pouring device of the proposed compilation.
