为了以短周期、低成本、高质量地生产汽车覆盖件金属模具，提出了一种基于快速成型和快速模具的模具制造新方法。首先，介绍了快速加工技术的工艺流程和基于分域并行加工创新思想的大型快速加工制造设备SSM-1600。SSM-1600设备填补了大型原型制造领域的空白。介绍了基于快速成型技术的生瓷铸型工艺。采用三维非线性热力耦合有限元分析方法，对汽车覆盖件模具在铸造凝固过程中的尺寸精度进行了分析。模拟结果可用于修改CAD模型，进一步提高模具精度。基于快速成型的汽车覆盖件模具制造系统经过实际生产验证，取得了成功。
To produce the metal die of an automobile deck part of high quality at low cost with a short cycle, a new method of manufacturing the die, based on rapid prototyping and rapid tooling, is proposed in this paper. First, the technological process of rapid processing (RP) technology and the large-scale rapid processing and manufacture (RP&M) equipment SSM-1600 that is based on the innovative idea of concurrent processing in a divided field are introduced. The SSM-1600 equipment supplies a gap in the field of making large prototypes. The technology of the unbaked ceramic mold casting process based on RP technology is also introduced. The method of 3D non-linear coupled thermo-mechanical FEM analysis is adopted to analyze the dimensional accuracy of the die of an automobile deck part during the casting solidification process. The simulation result can be used to modify the CAD model to further improve the precision of the die. The system of manufacturing the die of an automobile deck part based on rapid prototyping has gained success by the verification of practical production.
