Abstract
Molds (1) with annular mold parts (2, 3) divided by at least one plane of division (E--E) and forming a plurality of cavities (8) disposed at least substantially radially to a centrifugation axis (A--A), serve for the production of precision castings by centrifugal casting, especially of parts made of materials containing titanium for internal combustion engines, the molds (1) and a casting system being contained in a closed chamber. To automate production, at least one mold part (2, 3) is made to rotate in its own rotational guide, and two mold parts (2, 3) together with the corresponding rotational guides are brought to a closed position for the casting and solidification and to an open position for the removal of the precision castings. When cast, the precision castings are preferably joined together at their radially inward pointing ends by a circumferential ring of the solidified metal and thus a circle of castings can be removed from the opened mold by a manipulating system.
