Abstract
PURPOSE: To enable a double-flanged pipe free from neck cracking of flange parts to be centrifugally cast with ease of knock-out by using the metal molds inserted with insert metal molds provided with simple shrink absorbing mechanism at one end to the inside surface of an outer cylindrical metal mold.
CONSTITUTION: A double-flanged pipe is cast by using the metal molds consisting of an outer cylindrical metal mold 1, two-split insert metal molds 4, an asbestos ring 3, and an adjust ring 2 consisting of an inner cylindrical part 2a, a step part 2b and an outer cylindrical part 2c, rotating the metal molds by a conventional method and pouring molten metal. At the time when the poured molten metal solidifies and shrinks, the amount of shrinkage is absorbed by the deflection deformation of the asbestos ring 3, and this obviates making the removal of the insert metal molds 4 infeasible. The occurrence of a neck cracking phenomenon owing to the cracking at the root part of both flange parts of a casting 5 by yielding to the strength of the metal molds 4 is prevented as well. In the final, the adjust ring 2 of the ring 3 is inserted into the casting 5, and the sound double-flanged pipe is easily cast.
