摘　　要：镁合金作为一种绿色的轻质金属结构材料,由于其具有比重小、比强度和比刚度高、导热和导电性好、切削加工性好、优良的阻尼性和电磁屏蔽性、易于加工成型和回收等优点,因此广泛应用于汽车、电子、通讯等行业。压铸是镁合金最主要、应用最广泛的成型工艺,目前90%以上的镁合金产品是压铸成型的。文中分析了镁合金齿轮盖零件的结构工艺特点,介绍了压铸模的浇注系统及模具结构设计。As an environment-friendly light metallic structure material, Magnesium alloy possess low density, high specific strength and stiffness, the fine thermal conduction and fine electroconductibility, good machinability, good damping and electromagnetic shielding, easy-forming and processing, the advantages of recycling, so it is widely used in automobiles, electronics, telecommunications and other industries. Magnesium alloy die-casting is the most important, the most extensive application of the forming process, more than 90 percent of magnesium alloy products are forming by die-casting. This paper attalyses the structure characteristics of the magnesium alloy gear cover, introduces the design of gating system in die casting and the structural design of die-casting mould.
