Ways of improving service life of die casting die were proposed including structure design of die castings

design of die casting die

the selection of component materials

working and assembling of mould

heat treatment of materials as well as selection of processing parameters. It is pointed out that the die castings should be designed to thin-walled components with uniform thickness as possible

in which the round angle should be adopted at turn corner to avoid deep and narrow slot. The components in die casting die should be ensured rigidity and strength

and the impaction of liquid metal should be prevented at gating system design

and so on. Steel billet should be annealed after forging

and the surface of cavity in die casting die should be strengthened.
