摘　　要：分析了一种典型内翅片工业散热器型材的结构工艺性。对传统的挤压模进行了分析,得出分流孔设计不合理是造成产品质量得不到保证的主要因素,提出了一种新的分流孔布置方案。介绍了这种新的方案中分流孔设计、金属的供应方式、导流孔与导流槽结构、下模焊合室与工作带、模芯工作带等参数。实践表明,新的方案是有效的。The technological property of the structure of a typical inner fin industrial radiator section was analyzed.The traditional extrusion die is analyzed,and it is concluded that the unreasonable design of porthole hole is the main factor that cannot guarantee the quality of the product.A new layout scheme of porthole holes is put forward.The choice of parameters of this new scheme is introduced,including the design of portholes,the type of metal supply,the structure of guide holes and groove,the welding chamber and bearing of female die and the core bearing etc.Practice shows that the new scheme is effective.
