Rapid die casting equipment for aluminum alloy die castings

The rapid die-casting equipment for the aluminum alloy die castings comprises a die-closing die-casting mechanism and a die-casting die, the die-casting die comprises a female die, a male die, a grouting ejection block, a lifting mechanism and a high-pressure injection mechanism, a rectangular cavity is formed in the surface of the female die in a concave mode, a rectangular protruding block is arranged at the bottom of the male die, and after the female die and the male die are closed, the rectangular cavity and the rectangular protruding block are matched with each other. A forming die cavity of a rectangular frame body is formed between the rectangular cavity and the rectangular convex block; the forming die cavity is divided into the four forming runners which are not communicated with one another by the grouting ejection blocks, so that molten metal entering the forming runners can do smooth linear motion in the parallel direction of the forming runners and enters the forming runners in a laminar flow mo
