Copper rotor vacuum die-casting die

The invention relates to a copper rotor vacuum die-casting die which mainly comprises a movable formwork, a static formwork corresponding to the movable formwork, a core pulling sliding block mountedon the movable formwork, a moving die insert, a lower half block, an upper half block mounted on the core pulling sliding block, a static die insert and a pressing chamber, wherein the moving die insert and the lower half block are disposed on the movable formwork; and the static die insert and the pressing chamber are mounted on the static formwork. Exhaust blocks are arranged at the upper ends of the movable formwork and the static formwork respectively, each exhaust block is designed into three independent exhaust wave plates, and gaps of the exhaust wave plates on the two sides are smallerthan a gap of the middle exhaust wave plate. According to the copper rotor vacuum die-casting die, by the design of two exhaust channels, a mode of pumping out gas in the pressure casting process step by step is achieved, the
