To realize intelligent control to the rapid solidification of aluminum alloy wheel hub in the solid-liquid phase solidification temperature range,an ARM+DSP control system was designed to predict the temperature of the casting by obtaining the current mold temperature and filling speed in real time,thus to control the cooling system.The temperature and pressure parameters were set by ARM in the man-machine interface,and the pressure and temperature data were calculated and processed by DSP.According to the feedback data,the opening and duration of water cooling and air cooling in the cooling system could be regulated,then the accurate control of the casting temperature could be realized.Therefore,the wheel hub of low-pressure casting could solidify rapidly and sequentially in the solid-liquid phase solidification temperature range with better surface quality and mechanical properties.Thus,the intelligent control of the production of continuous low pressure casting aluminum alloy hub is realized.
