Abstract

PURPOSE: To obtain precise moldings free from cavity or fin at high working efficiency, by providing gas release route in a molding space extending in the direction opposing to the centrifugal force, in a molding mold made of special molding material, and molding centrifugally.
CONSTITUTION: A reverse mold made of agar is taken from, for instance, a dental pattern, and is filled with molding material to obtain a duplicate mold 21 of the pattern. This molding material consists of, by parts by weight, silica sand 100, hardening promoter 0.3W1, phosphate 3W15, and gelatinous silicic acid 12W18cc per solid matter 100 of said hardener 3W15, and is hardened by expanding to an extent to cancel the shrinkage of metal. A sheet 20 of specified thickness, a funnellike body 24, a connecting part 25, and strips 26, 27, which are all made of wax, are fitted to the mold 21, thus forming a wax mold 30, which is filled with said material. After hardening, the block is heated in a furnace to cause the wax to flow out, and while rotating the block 34 around a shaft 44, molten metal is poured in from a sprue 37 opened toward the shaft. The gas in the hollow space 35 in the molding space is effectively released from degassing routes 39, 40, so that cavity or fin may not occur.
