Optimizing control of dwell pressure- and solidification interval in die casting machines, measures temperature as control magnitude to end each phase

摘要

The die casting machine is controlled in terms of temperatures reached. Temperature (T3) corresponds with the end of the dwell pressure interval. Temperature (T4) corresponds with the end of the cooling interval. The temperature reached during the cycle is measured by a sensor and used by the computer to send signals to the machine controller. These signals terminate the dwell pressure applied by the hydraulic multiplier and/or open the moving mold halves. An independent claim is included for the corresponding sensor used for machine control.
