一种行星架粉末冶金成型模具 一种行星架粉末冶金成型模具
技术领域
本实用新型涉及粉末冶金成型领域，尤其涉及一种行星架粉末冶金成型模具。
背景技术
粉末冶金是制取金属粉末或用金属粉末（或金属粉末与非金属粉末的混合物）作为原料，经过成形和烧结，制造金属材料、复合材料以及各种类型制品的工艺技术。粉末冶金法与生产陶瓷有相似的地方，均属于粉末烧结技术，因此，一系列粉末冶金新技术也可用于陶瓷材料的制备。由于粉末冶金技术的优点，它已成为解决新材料问题的钥匙，在新材料的发展中起着举足轻重的作用。
行星架在通过粉末冶金成型的模具,由于行星架的形态特性,行星架的粉末冶金模具中的其中两个冲头模具采用的是一体式结构,但是由于金属的粉末添加量问题,导致一体式的冲头在压铸成型时容易产生断裂的问题。
实用新型内容
本实用新型要解决的技术问题是提供一种行星架粉末冶金成型模具；解决一体式行星架粉末冶金成型模具由于粉末的添加量导致行星架成型时容易出现断裂的问题。
为解决上述技术问题，本实用新型的技术方案为：一种行星架粉末冶金成型模具，包括第一模具、第二模具、第三模具和总模具座；其创新点在于：所述第一模具、第二模具和第三模具由各自独立的模具座支撑；
所述总模具座上设置有容纳第一模具、第二模具和第三模具穿过的模型孔和容纳各自模具座的凹槽；所述第一模具、第二模具和第三模具穿过总模具座上的模型孔并通过各自的模具座安装在总模具座上；第一模具的水平高度低于第二模具的水平高度；
所述第三模具位于第一模具和第二模具之间；
所述第三模具在总模具座上的安装高度低于第一模具和第二模具的高度；
所述第一模具、第二模具、第三模具和总模具座组成该行星架粉末冶金成型的下模具；
