Ultra-large integrated die-casting die for die-casting magnesium-aluminum alloy castings

The invention relates to an ultra-large type integrated die-casting die for die-casting magnesium-aluminum alloy castings, which belongs to the technical field of intelligent manufacturing, and comprises an air pressure device, a metal tank filled with molten metal, a die cavity, a rotating motor and a rotating shaft, the air pressure device is communicated with the metal tank, and the metal tank is connected with the die cavity through a feeding pipe; the mold cavity is obliquely arranged at the top of the metal tank, the mold cavity is coaxially connected with the rotating motor, the two ends of the rotating shaft are coaxially connected with the mold cavity and the rotating motor correspondingly, and due to the fact that the mold cavity is obliquely arranged, bubbles located in the mold cavity can move to the side wall of the top of the mold cavity; the knocking assembly knocks the side wall of the top of the die cavity, bubbles in the die cavity are broken, the probability of generation of the bubbles in
