Abstract
A stabilizing ring assembly for stabilizing a mold in a centrifugal pipe casting machine during operation includes a plurality of ring segments mounted on the mold and cooperating to form an annular ring retained in the mold by a plurality of resilient O-rings positioned in grooves extending around the annular ring with the O-rings fitting within and being compressed radially by the casting machine housing surrounding and rotating with the mold, and water flow passages are formed in the ring segments to permit the flow of cooling water axially of the casting machine between the internal surface of the housing and the external surface of the mold.
