The objective of this thesis is to design an intelligent control system for die casting processes involving cooling of a die with multiple channels. The work consists of two parks. First, a correlation between die insert temperature and cooling water outlet temperature is established, which can be used to deduce local die surface temperatures without destructively inserting thermal sensors into a die from its back. Second, a new on-line thermal management scheme is proposed based on an intelligent real-time monitoring and control system (IRMCS) developed for a die insert containing multiple cooling channels. In this scheme, extra cooling water lines controlled by a pump and solenoid valves are hooked up to each established cooling channel. The system is capable of monitoring temperature signals from the die insert and flow rate signals from the cooling lines on the basis of its built-in control algorithms. Pump and solenoid valves can be actuated either automatically or manually to introduce additional cooling water to the die insert for preventing die overheating.
