ABSTRACT:
Centrifugal casting apparatus comprising a rotatable sleeve supported at a fixed axial location and having a conically tapered internal surface, and a driving sleeve axially spaced with respect to the rotatable sleeve and having a conically tapered internal surface opposed to the internal surface of the rotatable sleeve. The driving sleeve is driven in rotation and it is axially displaced with respect to the rotatable sleeve. A split mold assembly is disposed between the rotatable sleeve and the driving sleeve and includes a casing and a plurality of mold segments slidably supported by the casing. The mold segments are radially moveable towards and away from the axis of rotation between a closed mold position and a opened mold position. The mold segments can be locked in the open and closed positions. Cone elements are secured to the mold segments and cooperatively define conical elements at respective ends of the mold assembly which face the conically tapered internal surfaces of the sleeves with the mold segments in closed position. The conical elements are of corresponding taper as and engageable in the conically tapered surfaces for driving the mold assembly in rotation. Molten metal can be introduced into the mold assembly via the rotatable sleeve.
