摘　　要：采用实型铸造技术实现了汽车覆盖件模具的近终成形铸造,选择适当化学成分的模具钢材料进行浇铸,得到汽车覆盖件模具铸件,与同化学成分的锻造模具进行对比磨损试验。试验结果表明,实型铸造法得到的模具耐磨性优于锻造磨具。实型铸造法缩短了模具的成形及加工周期,降低了加工成本,实现了快速铸造,节省了材料及生产成本,同时提高了国内车辆覆盖件铸造模具的制造水平。By using the full mold casting technology, the near-net-shape of automobile panel die can be achieved. And automobile panel die castings were achieved by selecting mold steel materials with the appropriate chemical composition. The wear comparison experiment between the casting die and the forging die with the same chemical composition were made. The experiment results show that the die by full mold casting process has a better wear resistance than the forging die. Full mold casting process can shorten the molding and processing cycle, reduce the manufa^turing costs, realize the rapid casting, save the materials and the production costs, and improve the domestic manufacturing level of the automobile panel die.
