摘　　要：传统的铸造因铸型制备过程复杂、生产周期长、成本高,不适合单件、小批量生产和新产品试制,研究利用光固法与熔模铸造相结合的工艺制造变矩器导轮功能样件,用于变矩器性能试验.首先利用快速成型设备制作导轮的SLA原型,随后对原型进行沾浆、淋砂、焙烧制成型壳,再经熔炼浇注后得到导轮功能样件.利用此方法,可以实现导轮的快速铸造,从而节约模具费用,缩短新产品开发周期.The high costs and long lead-time associated with the fabrication of casting mold render conventional investment casting uneconomical for new product development, single part or small quantity production. In this paper, the torque converter impeller＇s function sample, which is used for the torque converter test, can be obtained by the craft combined stereolithography with fired mold casting. The basic craft process is that： first, impeller SLA prototype can be manufactured by the rapid prototyping equipment, then comes the process of moistening slurry, drench sand and roasting type to make the shell, in the end, impeller＇s function sample can be obtained after smelting casting. By this method, mould＇s cost can be saved and the new product＇s construction cycle can be cut.
