摘　　要：介绍了水冷式铝合金电机壳的结构特征、应用情况和电机壳用铝合金型材挤压模的传统结构及其不足之处。提出了一种新的模具结构,新的结构采用的是由三件组成的分流模,是在传统结构基础上增加了一个前置分流板,可以降低挤压力和提高模具的强度;同时在上模中采用了子母上模进行镶嵌的结构方式,这种结构可以简化模具加工、节约材料和提高模具的制造精度。实践表明,新的模具结构消除了产品内腔出现椭圆和壳壁厚度不均匀的现象,是一种值得推广的模具结构。The paper introduces structure characteristics and applications of water-cooled aluminum alloy motor housing,the traditional structure of the aluminum alloy extrusion die for motor housing,and the shortcomings of traditional structure.A new die structure is pro-posed,which is a three-piece split die.On the basis of the traditional structure,a front splitter plate is added,which can reduce the extrusion pressure and improve the strength of the die.At the same time,the structure of the sub-mother die is adopted in the male die,which can simplify the processing,save the material and improve the manufacturing precision of the die.The practice shows that the new die structure eliminates ellipse in the cavity and uneven wall thickness of the housing,worthy of replication and promotion.
