Abstract

PURPOSE: To obtain the branched pipe of good quality with good efficiency by using the integral mold comprising assembling the facing mold of the side making contact with molten metal with split molds by CO2 molds then setting the same in a metal mold and packing the spacing between the same and the metal mold with the specific material.
CONSTITUTION: The facing mold by the CO2 mold of the portion in contact with molten metal is sand-molded to split molds 4A, 4A which are vertically bisected. Here, foamed resin is used for the pattern 8 for branched pipe and a core metal 11 for reinforcement is protruded at both ends in the corresponding position outside the sand mold to the upper and lower molds 4A, 4A, whereby fastening jigs 12, 12 are formed. Thence, the upper and lower molds 4A, 4A are coupled by means of bolts and are assembled to a facing mold 4A, after which it is set by way of an end plate 3 into a rotary mold 2 for centrifugal casting, thence furan back sand is packed in the spacing between the skin mold 4 and flask 2 to form the furan mold 4B. Centrifugal casting is done by using the above-mentioned metal mold 2. As compared to conventional methods, the difficulty in molding the sand mold for the branched pipe of intricate shape with plural branch pipes is solved and at the same time the branched pipe of sound and good quality may be obtained.
