ABSTRACT:
A vacuum casting machine has a rotary table obtaining motion from a self-contained drive and accommodating chambers with casting molds. In turning, the rotary table causes each of the chambers to register in succession with an opening in a melting chamber through which metal is being poured. This arrangement of mold chambers enables partial overlapping in time of such processes as preparing a mold for pouring, the melting of charge and accumulating melt in the melting chamber in a requisite amount, and the cooling of each mold with the casting. This all considerably increases the production rate of the machine.
