摘　　要：通过典型太阳花散热器铝型材作为例子,介绍了这类产品的结构特征,并提出了一种新型模具结构。这种结构与传统模具的主要不同在于,采用了模孔镶块以及将金属的焊合室设计在上模。介绍了模具结构参数的设计与选择方法,包括分流孔的数量与布置、分流孔之间的面积关系、焊合室的结构、工作带的选择及模孔的镶块结构等。介绍了该模具制造的关键技术与普通模具的不同主要体现在电加工方面。实践表明,采用新的模具结构和新的模具包加工工艺是有效的,可以降低太阳花散热器型材挤压过程的挤压力,并大幅提高模具的强度,解决了齿臂过早断裂而导致模具失效的问题。Through the typical sunflower radiator aluminum profile as an example, the structural characteristics of this kind of products are introduced. A new type of die structure is presented. The main difference between this structure and the traditional die is that the die hole insert is used and the metal welding chamber is designed in the upper die. This paper introduces the design and selection method of die structural parameters, including the number and arrangement of shunt holes, the area relationship between shunt holes,the structure of welding chamber, the selection of working belt and the structure of die holes insert block. The key technology of mould manufacture is introduced. The difference between mould and ordinary mould is mainly reflected in electric machining. The practice shows that the new die structure and new processing technology are effective and can be used to produce the profile of sun flower radiator.
