水轮机叶片类铸件造型模具制作工艺的改进

Modelling of a turbine blade type casting mould process improvements

为解决水轮机叶片类铸件造型模具制作周期长、模型手工处理难度大和后期变形的问题,通过对水轮机叶片类铸件铸造模具的改进设计,采用多层板U型咬合法,有效缩短了制作周期,解决了模型手工处理难度大和后期变形问题。经过批量设计和生产结果表明,改进后的模具设计工艺合理可行。

In order to solve the turbine blade casting molding mold production cycle is long, model manual processing difficulty and the late deformation problem, analysis is the main reason for the design is not rational, through improvement in turbine blade casting mould design and production, production cycle is long, model manual processing difficulty and the late deformation problems. After batch design and production results show that the improved mould design is reasonable and practical.
