Induction vacuumizing system for die-casting die

The utility model discloses a die-casting die induction vacuumizing system which comprises a die-casting machine, a vacuum device and a die-casting die. The vacuum device comprises a vacuum pump station and a vacuum pipeline; the die-casting die is connected with a vacuum pump station through a vacuum pipeline; a vacuum valve is arranged on the vacuum pipeline; a first pressure sensor is arranged on the vacuum pipeline; the device further comprises a vacuum control module. Linkage control among the die-casting machine, the vacuum device and the vacuum control module is achieved, and the vacuum valve and the first pressure sensor are arranged on the vacuum pipeline. Before injection of the die-casting machine, whether the pipeline is blocked or not is determined by opening the vacuum valve and detecting the pressure in the vacuum pipeline through the first pressure sensor, and whether the vacuum valve is closed or the closing condition of the vacuum valve is determined by closing the vacuum valve and detecting
