The invention discloses a copper rotor non-core-puling vacuum die casting mould which can be used for producing a long iron core copper rotor. According to the mould, a movable template and a core-pulling slide block are machined integrally, and a core-pulling slide block structure is eliminated; through the wedged structure design and rational tolerance design, the problem that the long iron corecopper rotor is eccentric is solved effectively; meanwhile, a casting cavity is used as a first vacuum-pumping system, and a mould space outside the casting cavity is used as a second vacuum-pumpingsystem; gas leaking from a fit clearance, an ejection system and the casting cavity is pumped out, so that the vacuum degree of the casting cavity is achieved effectively; the copper rotor after die casting has high concentricity, and the vacuum die casting process production of such copper rotors is achieved. 本发明公开了种能够用于生产长铁芯铜转子的铜转子无抽芯真空压铸模具，该模具将动模板与抽芯滑块加工成体，取消抽芯滑块结构，利用锲形结构设计和合理的公差设计，有效解决长铁芯转子的偏心问题，同时将铸件型腔作为第抽真空系统，将铸件型腔外部
