Form-undKernmassefürGiessereizwecke.
Es ist bekannt, Form-oder Kernmassen in der Weise herzustellen, dass man Formsand mit einem wässerigen Teig von Rapssamen- oder Leinsamenkuchen mischt, wodurch der Anteil an neuem Sande gegenüber dem bisherigen Masse etwas vermindert werden sollte. Auch die Verwendung eines mit Wasser angm8chten Gemisches von Sand, Mehl und Melasse ist bereits bekannt.
Den, Gegenstand der vorliegenden Erfindung bildet nun eine form- unk Kernmasse aus Sand, Raps- oder Leinsamenmehl und Melasse, welcher Kampfer zugesetzt ist.

so dass dasselbe. im Gegensatze zu der bekannten Masse ohne Kampferzusatz, nahezu unbeschränkt oftmalig verwendet werden kann.
Geeignete Verhältnisse für eine Formmasse sind z. B. die folgenden :

Mold and core materials for foundry purposes.
It is known to produce molding or core masses in such a way that molding sand is mixed with an aqueous dough of rapeseed or linseed cake, whereby the proportion of new sand should be somewhat reduced compared to the previous mass. The use of a mixture of sand, flour and molasses prepared with water is also already known.
The object of the present invention is now a shapeless core mass of sand, rapeseed or linseed flour and molasses, to which camphor is added.
EMI1.1
Filling the mold with the molten meta! ! evaporates immediately, whereby the escaping camphor fumes break up the sand so that the gases of the cast metal can quickly escape through the created fine openings and thus a perfect cast is created while preventing the formation of casting holes.
EMI1.2
so the same. In contrast to the known mass without added camphor, it can be used almost unlimited times.
Suitable ratios for a molding compound are, for. B. the following:
EMI1.3
also the weight of the sand, from which components only the thin dough or the mass of cream-like consistency is formed by adding water.
