Abstract

The mould, for Al, comprises a lower part contg. the mould cavity and a split upper part with melt infeed and riser holes. The moulds are made by tamping the coke-binder mix round a pattern, followed by firing.

Description

Dauerform zur Herstellung von metallischen Abgüssen Die Erfindung betrifft eine Dauerform zur Herstellung von metallischen Abgüssen, insbesondere aus Aluminium in Gestalt eines Kokillen-Unterteils mit einem Gießhohlraum und einem geteilten Kokillen-Oberteil.Permanent mold for the production of metallic casts The invention relates to a permanent mold for the production of metallic casts, in particular made of aluminum in the form of a mold lower part with a casting cavity and a split mold upper part.

Solche Formen bestehen zumeist aus Gußeisen und sind infolgedessen technisch und wirtschaftlich mit nur verhältnismäßig hohem Aufwand herzustellen. Sie sind auch für eine sehr große Anzahl von Abgüssen gedacht und infolgedessen vielfach hinsichtlich ihrer Anwendungsmöglichkeit beschränkt.Such forms are mostly made of cast iron and are consequently technically and economically to produce with only relatively high effort. They are also intended for a very large number of casts, and as a result often limited in terms of their possible applications.

Der Erfindung liegt die Aufgabe zugrunde, eine Dauergußform zu schaffen, die in der Herstellung billig ist und dabei einen nur geringen technischen Aufwand erfordert. An diese Form wird auch nicht die Forderung für die Herstellung einer sehr großen Anzahl von Abgüssen gestellt, sondern sie soll nur dazu ausreichen, ein paar hundert Abgüsse maximal zu ermöglichen.The invention is based on the object of creating a permanent casting mold, which is cheap to manufacture and only requires little technical effort requires. The requirement for the production of a made a very large number of casts, but it should only be sufficient to to allow a few hundred casts at most.

Diese Ziele werden bei einer wie eingangs erläuterten Dauergußform gemäß der Erfindung dadurch erreicht, daß sie besteht aus einer gebrannten Koks-Bindemittel-Masse.These goals are achieved in the case of a permanent casting mold as explained at the beginning achieved according to the invention in that it consists of a burned coke-binder mass.

Beispielsweise kommen hierfiir Petrolkoks, Pechkoks und als Bindemittel ein pechhaltiges Gemisch in Betracht.For example, petroleum coke, pitch coke and binders are used here a pitch-containing mixture into consideration.

Eine Ausführungsform der Erfindung ist in der Zeichnung beispielsweise wiedergegeben.An embodiment of the invention is shown in the drawing, for example reproduced.

Es bedeutet darin 1 das Kokillenunterteil mit dem Gießhohlraum, in dem sich das Negativ der beabsichtigten Darstellung befindet, zur Herstellung des Gusses werden auf das Kokallenunterteil 1 die beiden geteilten Oberhälften 3 und 4 aufgesetzt.It means 1 is the lower part of the mold with the casting cavity, in which contains the negative of the intended representation, for the production of the Gusses are on the Kokallenunterteil 1, the two divided upper halves 3 and 4 put on.

Diese Teile 3 und 4 besitzen in bekannter Weise den Einguß 5 und den Steiger 6. Die Form besteht aus einer gebrannten Koks-Bindemittel-Masse.These parts 3 and 4 have the sprue 5 and the in a known manner Steiger 6. The mold consists of a burnt coke-binder mass.

Die Herstellung der Form erfolgt in der Weise, daß die grüne Kohlemasse um ein Modellstück herum gestampft und anschließend gebrannt wird.The mold is made in such a way that the green coal mass stamped around a model piece and then fired.
