K- KERNSTÜTZENK- CORE SUPPORTS

K (Kunststoff)-Kernstützen aus Hartschaumstoff - vorzugsweise aus extrudiertem Polystyrol-Hartschaumstoff - zylinderförmig oder würfelförmig geformt. K (plastic) core supports made of rigid foam - preferably extruded polystyrene rigid foam - cylindrical or cube-shaped.

In der Gießereitechnik werden zur Herstellung von Gußstücken Formen verwendet, in die Kerne eingesetzt sind. Man unterscheidet hierbei Innenkerne, die die inneren Konturen von Gußstücken wiedergeben und demgemäß Außenkerne für die Außenkonturen, wobei zum Fixieren der Kerne in der Form Kernmarken und Kernstützen vorgesehen sind. Die Kernstützen dienen vor allen Dingen zur Einhaltung vorgegebener Wandstärken der Gußstücke.In foundry technology, molds into which cores are inserted are used to produce castings. A distinction is made between inner cores, which reproduce the inner contours of castings, and outer cores for the outer contours, whereby core marks and core supports are provided to fix the cores in the mold. The core supports serve primarily to maintain the specified wall thicknesses of the castings.

K-Kernstützen können beim Gießen von Aluminiumlegierung in Sandgußverfahren vorteilhaft eingesetzt werden - zum Beispiel beim Röhrenguß und beim Gießen von Hohlgußteilen, deren Innenkern einseitig durch ein Kernschloß eingespannt ist (Fig.l).K-core supports can be used advantageously when casting aluminum alloys in sand casting processes - for example in tube casting and when casting hollow castings whose inner core is clamped on one side by a core lock (Fig.l).

Ungleichmäßige Einströmung der Schmelze kann dazu führen, daß der Innenkern einseitig druckbelastet wird und dadurch eine Lageverschiebung erfährt, was fehlerhafte Gußstücke mit unterschiedlichen Wandstärken zur Folge hat. Dem wirken Kernstützen, die im kritischen Bereich plaziert wurden entgegen.Uneven inflow of the melt can lead to the inner core being subjected to pressure on one side and thus experiencing a positional shift, which results in faulty castings with different wall thicknesses. This is counteracted by core supports that have been placed in the critical area.

Die Erstarrungszeit der Aluminiumschmelze -vor allem bei geringen Wandstärken von zum Beispiel 4 bis 6 mm-ist kurz. Die schwer entflammbare Kunststoff-Kernstütze hält den Innenkern solange in Position, bis dieser vollständig von der Schmelze umspült ist und somit eine gleichmäßige Belastung erfährt.The solidification time of the aluminum melt is short - especially with thin walls of 4 to 6 mm, for example. The flame-retardant plastic core support holds the inner core in position until it is completely surrounded by the melt and thus experiences an even load.

Blatt 2 zum Schreiben an Deutsches Patentamt, MünchenPage 2 of the letter to the German Patent Office, Munich

Die K-Kernstütze hat gegenüber herkömmlichen Kernstützen aus Metall den Vorteil, daß auch im Bereich der Stütze eine homogene Gußwandung mit absoluter Dichtigkeit gebildet wird, da die K-Kernstütze beim Gießvorgang vergast und dadurch der Raum den die Stütze einnimmt in homogenes Gußgefüge übergeht.The K-core support has the advantage over conventional metal core supports that a homogeneous cast wall with absolute tightness is also formed in the area of the support, since the K-core support gasifies during the casting process and the space occupied by the support is thus transformed into a homogeneous cast structure.
