Mechanical part machining die

The utility model discloses a mechanical part machining die which comprises a machining bottom die, installation top plates are installed on the two sides of the machining bottom die through adjusting mechanisms, and machining top dies are installed on the outer walls of the installation top plates through disassembling and assembling mechanisms. According to the lifting device, the machining top die and the machining bottom die can be lifted relatively stably, the situation that a traditional top die is prone to shaking amplitude in the moving process is avoided, meanwhile, the situation that the position is prone to deviation when the top die is in butt joint with the bottom die is avoided, the stabilizing efficiency of the device in the using process is improved, and the production cost is reduced. And meanwhile, the machining top die can be replaced relatively conveniently, and the working efficiency of the device in the using process is improved. 本实用新型公开了一种机械零部件加工模具，包括加工底模，所述加工底模两侧通过调节机构安装有安装顶板，且安装顶板外壁通过
