Abstract:
The properties of the magnetic mold in magnetic mold casting directly determine the quality of the final cast parts. In this study, the magnetic mold properties in magnetic mold casting, were studied utilizing a coupled electromagnetic-structural method through numerical simulation. This study investigated key factors including equivalent stress, the distribution of tensile and compressive stresses, and the area ratio of tensile stress. It compared molds made entirely of magnetic materials with those made partially of magnetic materials. Simulation results indicate that as current increases from 4 A to 8 A, both the initial magnetic mold and the material-replaced magnetic mold initially show an increasing trend in equivalent stress, tensile-compressive stress, and the area ratio of tensile stress, peaking at 6 A before declining. After material replacement, the area ratio of tensile stress at 6 A decreases to 19.84%, representing a reduction of 29.72%. Magnetic molds comprising a combination of magnetic and non-magnetic materials exhibit sufficient strength and a reduced area ratio of tensile stress compared to those made entirely from magnetic materials. This study provides valuable insights for optimizing magnetic mold casting processes and offers practical guidance for advancing the application of magnetic molds.
