High-toughness self-strengthening aluminum alloy die-casting device and production process thereof

The invention belongs to the technical field of die casting, and particularly relates to a high-toughness self-strengthening aluminum alloy die casting device which comprises a machine tool and a lower die fixed in the machine tool. A high-toughness self-strengthening aluminum alloy die-casting production process comprises the following steps that S1, materials are guided into a lower die, an upper die is driven by an external hydraulic cylinder to move downwards into the lower die, and metal materials are subjected to extrusion forming; a workpiece is cooled and shaped through water flowing, the lopsided vessel is full until the lopsided vessel overturns after the water flows out, the water is poured out to push a swing plate to rotate, an ejector rod moves upwards to knock an ejector plate, connection between the workpiece and a mold is promoted to be loosened, cold airflow guided out of a vortex tube enters a cooling pipe to cool the water, and the water is repeatedly utilized; and meanwhile, the heated ai
