CENTRIFUGAL CASTING MACHINE

摘要

A centrifugal casting machine is provided to lower product defective proportion by making it possible to uniformly maintain cooling and solidifying rates of a casting as a whole through an even air contact over the entire mold and further improve mass production characteristics by easily separating a casting from the mold after casting. In a centrifugal casting machine comprising a disc type surface plate(20) that is driven to rotate, a mold(30) rotated in a state that the mold is held on the surface plate, and a molten metal-pouring mechanism for pouring molten metal into the mold, the centrifugal casting machine is characterized in that the mold includes a lower plate(36) laid down on the surface plate, a cylindrical body(34) coupled onto the lower plate, and an upper plate(32) which is coupled onto an upper part of the body, and which has a sprue(320) formed in the center thereof such that molten metal is poured into the sprue, wherein the lower plate is spaced apart from the surface plate such that air circulates between the lower plate and the surface plate, and wherein grooves(362,322) are recessed in regular patterns on an inner bottom surface of the lower plate and a bottom surface of the upper plate in a state that molten metal poured into the mold contacts with the inner bottom surface of the lower plate and the bottom surface of the upper plate.
