Abstract
The invention relates to an apparatus for the casting of cast parts according to the permanent mold casting method comprising: a pivotable retaining element (9) for holding a permanent mold (13, 16) a furnace (11) which may be connected to a low-pressure permanent mold (13) in such a way that melt may be fed to the low-pressure permanent mold (13) in accordance with the low-pressure process, and a melt feed device (17) by which melt may be fed to a gravity permanent mold (16), wherein the gravity permanent mold (16) may be mounted on the retaining element (9).
Claims18
Apparatus for the casting of cast parts comprising:
- a pivotable retaining element capable of alternatively holding a low-pressure permanent mold or a gravity permanent mold, wherein the pivotable retaining element is compatible with both the low-pressure permanent mold and the gravity permanent mold but only holds one at a time,
- a furnace which is embodied to be connected to the low-pressure permanent mold in such a way that melt may be fed from below to the low-pressure permanent mold, held by the retaining element, in accordance with a low-pressure process, and
- a melt feed device which is embodied for feeding to the gravity permanent mold held by the retaining element from the furnace, when configured for a gravity casting process, wherein the gravity permanent mold has in its upper area a pouring basin which is open at a top, to which the melt is fed from above according to a gravity molding process, the apparatus configured to perform a method for casting of the cast parts comprising:
- during the low-pressure process, mounting the low-pressure permanent mold in the pivotable retaining element and feeding melt from the furnace to the low-pressure permanent mold, via a melt line of the apparatus according to a low-pressure casting configuration,
- converting to a gravity casting configuration by mounting the gravity permanent mold in the pivotable retaining element to replace the low-pressure permanent mold, and
- during the gravity casting, feeding melt from the furnace to the gravity permanent mold using a melt feed device of the apparatus according to a gravity casting configuration, wherein the pivotable retaining element is compatible with both the low-pressure permanent mold and the gravity permanent mold.
Method for casting of cast parts with a casting apparatus according to low-pressure casting with a low-pressure permanent mold and a gravity casting with a gravity permanent mold, the method comprising:
- during the low-pressure casting, mounting a low-pressure permanent mold in a pivotable retaining element of the casting apparatus and feeding melt from a furnace to the low pressure permanent mold, via a melt line of the casting apparatus according to a low-pressure casting configuration,
- converting to a gravity casting configuration by mounting, the gravity permanent mold in the retaining element to replace the low-pressure permanent mold, and
- during the gravity casting, feeding melt from the furnace to the gravity permanent mold using a melt feed device of the casting apparatus according to a gravity casting configuration, wherein the pivotable retaining element is compatible with both the low-pressure permanent mold and a gravity permanent mold.
