Description
Verfahren zur Herstellung metallischer Gußstücke mittels modellplatten Gegenstand des Hauptpatents ist ein Verfahren zur Herstellung metallischer Gußstücke, das im wesentlichen folgende Schritte umfaßt: i. Herstellung von Modellen, 2. Herstellung einer Hohlform durch Umgießen der Modelle mit leichtflüssigen Gußwerkstoffen, 3. Herstellung einer Modellplatte nach den Hohlformen, Herstellung der endgültigen, Gußform nach der Modellplatte, 5. endgültiger Guß.Process for the production of metallic castings using model plates The subject of the main patent is a process for the production of metallic castings, which essentially comprises the following steps: i. Manufacture of models, 2. Manufacture a hollow form by casting around the models with low-viscosity casting materials, 3. Production of a model plate after the hollow forms, production of the final, Casting mold after the model plate, 5th final casting.
Die nach dem Verfahrensschritt 3 hergestellten Modellplatten haben den Nachteil geringer mechanischer Widerstandsfähigkeit, so daß sie an empfindlichen Stellen, wie Ecken u. dgl., leicht verletzt werden.Have the model plates produced according to process step 3 the disadvantage of low mechanical resistance, so that they are sensitive Places such as corners and the like are easily injured.
Gemäß der Erfindung wird dieser Nachteil in der Weise behoben, daß man die Modellplatten aus einem geeigneten Metall, z. B. Kupfer, und zwar nicht durch Gießen, sondern auf galvanischem Wege herstellt. Auf diese Weise hergestellte Modellplatten besitzen ausgezeichnete mechanische Festigkeiten und geben überdies die gewünschte Form mit größter Genauigkeit wieder, da sie auf kaltem Wege hergestellt sind und daher keinerlei Schwindung aufweisen, die beim Vergießen von geschmolzenen Stoffen unvermeidlich ist.According to the invention, this disadvantage is eliminated in such a way that the model plates made of a suitable metal, e.g. B. Copper, and not by casting, but by galvanic means. Manufactured this way Model plates have excellent mechanical strength and also give the desired shape with the greatest accuracy, since it is produced by cold means and therefore do not show any shrinkage that occurs when pouring molten Fabrics is inevitable.
Wenn die Hohlform aus einem nichtleitenden Stoff besteht, so wird sie zum Zwecke der galvanischen Abbildung in bekannter Weise leitend gemacht, z. B. mit Graphit eingerieben.If the hollow shape is made of a non-conductive material, so will made them conductive in a known manner for the purpose of galvanic imaging, e.g. B. rubbed with graphite.
Die Vorteile des neuen Verfahrens kommen zwar besonders bei Verfahren nach dem Hauptpatent, also zur Herstellung von Fertigguß zur Geltung; doch ist es auch möglich, das Verfahren für andere Herstellungsarten zu verwenden.The advantages of the new process come especially with processes according to the main patent, i.e. for the production of finished castings; Yes it is it is also possible to use the process for other types of production.
