ABSTRACT:
A computerized die-casting machine control includes a microcomputer and a programmable controller having presettable inputs to establish a desired machine operating sequence. Temperature sensors at the holding furnace, cover die, ejector die, gate and at the die impact bushing monitor the die casting variables and produce input signals to the shot-control micro-computer. The micro-computer is programmed to take pre-programmed actions to correct out of tolerance conditions in the machine on a continuous on-line basis during machine operation.
