Abstract
Core comprises a base material based on salt or carbon and inorganic and/or organic binders for hardening during the production and maintenance during casting.
Description
Die Erfindung betrifft Gusskerne aus einem Werkstoff auf der Basis von Salz oder Kohlenstoff zur Verwendung bei der Herstellung von metallischen Gussteilen.The The invention relates to cast cores made of a material based on Salt or carbon for use in the manufacture of metallic castings.
Bei der Herstellung metallischer Gussteile ist es notwendig, in den Gussteilen vorgesehene Hohlräume in der Gießform durch Formkörper auszufüllen, die die Konturen des Hohlraums genau ausfüllen. Diese Formkörper sind die sogenannten Gusskerne, die die Funktion eines Platzhalters für den späteren Hohlraum einnehmen. Die Anforderungen, die an die Gusskerne gestellt werden, sind hoch. Sie müssen sich leicht herstellen lassen, formstabil und konturengenau sein, die für ihre Herstellung verwendeten Werkstoffe sollen weder die Umwelt belasten, noch gesundheitliche Gefährdungen verursachen und schließlich sollen nach dem Guss die Rückstände eines Kerns möglichst einfach, schnell und vollständig entfernt werden können.at In the production of metallic castings it is necessary in the Castings provided cavities in the mold through moldings fill, which exactly fill the contours of the cavity. These shaped bodies are the so-called casting cores, which serve the function of a placeholder for the later cavity taking. The requirements placed on the casting cores are high. You need to be easy to produce, dimensionally stable and contoured, the for The materials used in their production should not harm the environment burden, still cause health hazards and eventually should after casting the residues of a Kerns as possible easy, fast and complete can be removed.
Um diese Anforderungen zu erfüllen, werden auf das zu gießende Metall und das daraus resultierende Gießverfahren abgestimmte Werkstoffe für die Gusskerne verwendet, wobei den dabei verwendeten Bindemitteln eine besondere Bedeutung zukommt. Einerseits müssen die Kerne bei Gießtemperatur formstabil sein, andererseits müssen sich die Kerne nach dem Guß leicht und vollständig entfernen lassen.Around to meet these requirements will be on the to be poured Metal and the resulting casting process matched materials for the casting cores used, with the binders used a special Meaning. On the one hand, have to the cores are dimensionally stable at casting temperature on the other hand have to be the cores are easy after casting and completely have it removed.
Aufgabe der vorliegenden Erfindung ist es, Gusskerne aus einem keramischen Werkstoff vorzustellen, welche beim Gießen die notwendige Festigkeit gewährleisten und sich leicht und vollständig entfernen lassen.task The present invention is to cast cores from a ceramic To present material, which during casting the necessary strength guarantee and easy and complete have it removed.
Die Aufgabe wird durch die in den Ansprüchen beanspruchten Merkmale gelöst. Die Herstellung der erfindungsgemäßen keramischen Gusskerne erfolgt nach Verfahren, wie sie zur Herstellung von Formteilen in der keramischen Technologie bekannt sind.The The object is achieved by the features claimed in the claims solved. The production of the ceramic casting cores according to the invention takes place by processes such as those used to produce molded parts in the ceramic Technology are known.
