  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.

 Füllung der Gussform mit dem geschmolzenen   Meta ! ! sogleich verdampft, wobei   die entweichenden Kampferdämpfe den Sand   aufschliessen,   so dass die Gase des Gussmetalles durch die geschaffenen feinen Öffnungen rasch abziehen können und dadurch, unter Verhinderung der Bildung von   Gusslöchern,   ein vollkommener Guss entsteht Der zugesetzte Kampfer ver-

 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.

Claims (1)

In den Fällen. wo der so behandelte Sand zur Herstellung von Kernen dienen soll, kann der Anteil an Melasse von 5 bis auf 50% des Sandgewichtes erhöht werden, je nach dem herzustellenden Gegenstand ; der Zusatz von Kampfer variiert von 1 bis 30,', des Sandgewichtes. i'ATEXI-ANSPRUCH : Form- und Kernmasse aus Sand, Raps- oder Leinsamenmehl und Melasse, gekennzeichnet durch den Zusatz von Kampfer. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. In the cases. where the sand treated in this way is to be used for the production of cores, the proportion of molasses can be increased from 5 to 50% of the weight of the sand, depending on the object to be produced; the addition of camphor varies from 1 to 30% of the weight of the sand. i'ATEXI CLAIM: Molding and core mass made from sand, rapeseed or linseed flour and molasses, characterized by the addition of camphor. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
