ABSTRACT:
A casting-by-squeezing mold having a base, mold halves, and enclosing cheeks. One of the mold halves is movably mounted on the base so that the two mold halves can be driven apart and brought together to form a complete mold. The internal surfaces of the base, mold halves and cheeks form a cavity. One of the mold halves has projections which divide it into three chambers. The first, lower chamber is a metal receiving chamber; the second, side chamber is a feeding chamber; the third, central chamber is a molding chamber. A variable-volume cavity is provided, which communicates with the metal receiving chamber so that the level of the metal in the receiving chamber can be adjusted to a predetermined level.
