Concrete Measures to improve the Life of Die Casting Mold (1) In THIS PAPER, THE FORMS AND CAUSES OF DIE CASTING DIE FAILURE ARE DISCUSSED, AND THE FACTORS AFFECTING DIE LIFE and specific countermeasures are discussed from the aspects of die material, heat treatment, design, manufacturing and processing, die casting technology, production operation, die maintenance and so on. The main forms of die casting die failure are: ①the alternating stress of thermal expansion and cold contraction, the long-term frequent repeated cycle, and the thermal fatigue cracking crack on the surface of the die; ② The mold overall cracking and damage...
