Design of automotive steering gear die-casting die and numerical simulation for forming process
The forming process of automotive steering gear was analyzed.According to the deep casting cavity and complex shape of the forgings,a die-casting die with one-cavity was designed,and hydraulic side core-pulling mechanism was adopted.The specific pressure of ejection was se-lected 85MPa,the casting temperature was 650℃,the preheating temperature of the die was 150℃,the holding time was 5 s,and the filling speed was about 0.22 s.The UG12.0 software was used for the establishment of the three-dimensional model of the die components,and finally the MAGMAsoft software was used for numerical simulation and analysis on the casting process of the filling,cooling,shrinkage,which to verify the rationality of the mould design,so as to put into actu-al production.
