摘要： 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.

摘要： To produce precision castings from a melt, use is made of a metallic casting wheel (1) which has an annular distribution channel (4) and a plurality of interchangeable casting moulds (6), each having at least one filling opening (6a). The melt quantity per casting operation is chosen here such that the casting moulds (6) and the distribution channel (4) are filled with the melt upon the rotation of the casting wheel (1) about its axis (A—A), in such a way that after the solidification of the melt the precision castings are held together by a ring of the casting material which is formed in the distribution channel (4), the so-called circulating material for new casting processes, and are removed from the casting wheel (1) together with the casting moulds (6), whereupon the precision castings are separated from the ring. In order to be able to produce precision castings with complicated three-dimensional shapes, in particular with undercuts, by this means as well, the casting moulds (6), which can be used only once and are destructible for the purpose of demoulding, are selected from a ceramic material and are attached in a positive-locking and interchangeable manner to the casting wheel (1) and so as to protrude therefrom. As a result, the circulating material can be fed uncontaminated to a recycling process.
