Design of semi-solid die casting die for box shell and its die casting

The semi-solid die casting die for box shell was designed and manufactured. By using Flow-3D software, the filling and solidification process of semi-solid rheological die-casting was simulated, and verification experiment was conducted. The results show that the temperature of die has the obvious effects on semi-solid die casting process. The optimized parameters for semi-solid die casting were presented as follows: injection velocity of 1 m/s, pre-heating temperature of mould at 260 ℃ and slurry temperature of 590 ℃.
