摘　　要：实心铝型材在挤压生产和模具制造方面具有较为容易的特点,因而得到了广泛的应用。而实心型材生产中模具是关键。为了降低生产成本,在实际生产大断面实心型材时都采用导流宽展模。通过实际例子介绍了大断面实心型材导流模的设计。模具设计中的有关参数如模具结构、金属的流速与供应、宽展设计、模孔弹性变形补偿等已经在生产实践中得到验证,表明它们是可行的和有效的,供同行参考。The solid aluminum profiles, due to easy extrusion and die manufacturing, are widely used. The die plays a key role in production of solid profiles. Flow-guided dies are widely used in actual production of aluminum solid profiles with large section to reduce cost. The design of the flow-guided die for aluminum solid profiles with large section is introduced through practical examples. Its design parameters are tested in the production practice, such as the die structure,metal flow and supply, spread design and the compensation for deviation due to elastic deformation, etc. The results show that they are feasible and effective, for reference only in this industry.
