It is difficult to manufacture radiator component using integrated structural core in moving die casting die because of thin blades

small gap among the blades as well as deep circlar groove. The use of inserted block for the core in moving die not only overcame the difficulties in mold cavity making but also improved the mold filling and gas release so as to obtain sound casting. The design essentials of the die were described on the basis of analyzing the technological characteristics of die casting for the radiator. The die casting machine was selected by calculating the swelling force and clamping force. The processing parameters and practical die structure were given. Finally running principle of the die and die casting technology were expounded.
