METHOD AND APPARATUS FOR CHARGING METAL TO A DIE CAST MACHINE

摘要

An automatic ladling system is described for delivering a molten metal to the mold or die (14) of a molding or casting machine. The ladling system comprises a programmable logic controller (PLC) for monitoring and controlling the sequential delivery of shots of a precise quantity of molten metal from a furnace or holding pot (10) to a shot delivery apparatus (18) of the casting machine. In the preferred system, the PLC also monitors and/or controls the temperature of the molten metal in the holding pot (10), the temperature of the molten metal in a metal transfer system (16), the operation of a pump (32) for pumping molten metal from the holding pot to the shot delivery apparatus, the level of molten metal in the pot, and the operation of the casting machine.
