Description

Verfahren zur Herstellung von Modellen zum Abgießen, insbesondere von Maschinenschildern Schilder, wie sie insbesondere an Maschinen angebracht werden und die die näheren Angaben z. B. über Getriebe, Motor, Typ, Fabriknummer, Leistung, Zugkraft, Fahrgeschwindigkeit, Umdrehungszahlen oder Gestellnumnier aufweisen, wurden bisher in der Weise hergestellt, daß man auf ein Blech Bleibuchstaben und Zahlen aufklebte, dieses in Blei abgoß und darin die Buchstaben bzw. Zahlen nachgravierte. Dieses Modell wurde dann in der Weise weiter behandelt, daß man hiernach eine Sandform herstellte und aus dieser Sandform den endgültigen Abguß nahm.Process for the production of models for casting, in particular of machine signs Signs such as those attached to machines in particular and the details z. B. About gear, engine, type, serial number, power, Have traction force, driving speed, number of revolutions or frame numming hitherto manufactured in such a way that lead letters and numbers are placed on a sheet of metal glued on, cast this in lead and re-engraved the letters and numbers in it. This model was then further treated in such a way that afterwards a sand mold is made and took the final cast from this sand mold.

Das Nachgravieren, das von Hand geschehen muß, ist aber eine außerordentlich zeitraubende Arbeit, die daher das Schild wesentlich verteuert.The re-engraving, which has to be done by hand, is extraordinary time-consuming work, which therefore makes the sign much more expensive.

Durch die Erfindung wird nun ein Verfahren angegeben, bei dein sich dieses umfangreiche Nachgravieren erübrigt; die Kosten ermäßigen sich hierdurch ganz erheblich.The invention now provides a method in which you this extensive re-engraving is unnecessary; this reduces the costs quite considerably.

Dieses wird erfindungsgemäß dadurch erreicht, daß von einer Negativgravur, z. B. unter Verwendung von vulkanisierbarem Gummi, ein Positivabdruck genommen und dieser in an sich bekannter Weise weiter behandelt wird, also mit Sandform und Abguß.This is achieved according to the invention in that from a negative engraving, z. B. using vulcanizable rubber, a positive impression is taken and this is further treated in a manner known per se, that is, with a sand mold and casting.

In eine Platte aus einer Spezialzinklegierung wird z. B. die Schildbeschriftung als Negativ maschinell eingraviert. Auf diese Platte wird dann eine Gummischicht aufgebracht, der Gummi fließt in die Ausgravierungen und wird vulkanisiert. Diese Gummiplatte wird von der Zinkplatte abgehoben. Die Beschriftung ist vollkommen klar nunmehr als Positivschrift auf der Gummiplatte vorhanden. Irgendein Nacharbeiten ist nicht erforderlich. Daraufhin wird von dieser Platte eine Sandform genommen, die dann zum Abgießen benutzt wird.In a plate made of a special zinc alloy z. B. the sign lettering Machine-engraved as a negative. A rubber layer is then placed on this plate applied, the rubber flows into the cavities and is vulcanized. These The rubber plate is lifted from the zinc plate. The lettering is perfectly clear now available as positive writing on the rubber plate. Some rework not necessary. Thereupon this plate becomes a sand mold taken, which is then used for pouring.
