摘　　要：液态金属流动性测试实验是材料成形及控制工程专业(铸造方向)非常重要的一个大型综合性实验。流动性是液态金属一个非常重要的铸造性能指标,螺旋形流动性实验是测定液态金属在砂型中流动性常用的实验方法,同心三螺旋形流动性试样造型模板是螺旋形流动性实验方法中最主要的工装用具。本文根据该铸件的结构特点设计了初步铸造工艺方案,并应用ProCAST数值模拟软件优化了其铸造工艺方案,然后基于优化的铸造工艺方案,利用数字化无模铸造精密成形技术完成了同心三螺旋形流动性试样造型模板铸件产品的实际生产。最后利用生产的造型模板铸件,对本科生开设了液态金属流动性测试实验课,取得了良好的实验教学效果。The liquid metal fluidity test experiment is a very important large-scale comprehensive experiment for the major of materials forming and control engineering(casting direction).Fluidity is a very important casting performance index of the liquid metal.The spiral fluidity experiment is a common experimental method to determine the fluidity of the liquid metal in sand molds.The concentric triple spiral fluidity sample molding template is the most important tooling for the spiral fluidity experiment method.In this paper, according to the structural characteristics of the molding template casting, a preliminary casting process scheme was designed and then was optimized with the ProCAST numerical simulation software.Subsequently, based on the optimized casting process scheme, a concentric triple spiral fluidity sample molding template casting product was actually produced by using the digital pattern-less casting precision forming technology.Finally, with the molding template casting produced, the experimental course of the liquid metal fluidity test was conducted for the undergraduates majored in the materials forming and control engineering in our university, and a good experimental teaching effect was achieved.
