Abstract
The invention relates to a rotary mold for centrifugal casting of an alloy. The mold comprises liners (135a) housed in hollow exoskeletons (137a). The exoskeletons retain the liners against the centrifugal force, during the casting, while the mold is spinning.
Claims10
A rotary mold mounted to spin about an axis, for centrifugal casting of an alloy, the mold comprising:
- a plurality of liners, each defining a recess for receiving the alloy, and extending radially about said axis;
- and
- at least one exoskeleton inside which the liners are disposed, and that retains said liners against a centrifugal force;
- wherein, transversely to the radial direction in which each liner extends, a space exists peripherally between said liner and the exoskeleton that surrounds it.
