4. An aluminum alloy processing apparatus according to claim 3, wherein a processing method of the aluminum alloy processing apparatus is provided, characterized in that: the method comprises the following steps:
step one, limiting, the jack (1) jacks up the closing cover (3), the shell is placed in the sand storage wall (2), gravel is arranged at the lower position of the inner side surface of the sand storage wall (2), the partition plate (71) isolates the gravel, the upper position of the surface of the shell is limited by the elastic wall (73), the cylinder (42) controls the elastic wall (73) to clamp the shell in a servo manner, the blocking strip (74) has certain rigidity so that the shell is clamped, the elastic wall (73) is provided with the servo control of the elastic matching cylinder (42) to prevent the surface of the shell from being clamped rigidly to be broken, and fine gravel wraps the lower position of the surface of the shell to prevent the shell from being broken in the casting process;
step two, cladding, wherein the total volume of the grits is smaller than the volume of the sand storage wall (2), after the upper position of the surface of the shell is limited by the elastic wall (73), the water pump (61) is used for pumping water into the rubber bag (62), the rubber bag (62) is expanded to squeeze the grits at the lower position of the partition plate (71), the grits gradually flow to the surface of the shell and gradually clad the shell, in the process, the magnet (55) in the stirring blade (45) attracts the magnet to slide on the inner side surface of the slip guide ring (63), and the scraping plate (65) stirs the grits outside the shell, so that the grits uniformly clad the lower position of the surface of the shell, and the problem of local stress overlarge and fracture during casting of the shell is avoided;
step three, diversion, the mixed metal material is melted to form a molten fluid state, the air cylinder (42) drives the screw rod (53) to move downwards, the bottom end of the screw rod (53) stretches into the inner part of the shell, the molten fluid has the characteristic of viscous wall climbing, the fluid is guided by the necking wall (52) to flow the screw rod (53) forward to the inner part of the shell, the surface of the lubricating body (54) is smoother, the fluid splashing can be reduced, and when the fluid is gradually filled into the shell, the air cylinder (42) drives the lubricating body (54) to gradually leave the shell upwards, so that the cold isolation defect of products caused by the fact that the metal fluid is impacted into the shell and involved in bubbles can be effectively avoided;
step four, molding, when the jack (1) drives the closing cover (3) to move upwards, the closing cover (3) is jacked up and then the molded shell obtained by the investment pattern is flexibly limited through the regulating and controlling component (7), then the jack (1) drives the closing cover (3) to be combined with the sand storage wall (2), aluminum and other metal materials are placed above the casting wall (41), the heating strip (46) heats and melts the mixed metal materials to form aluminum alloy molten fluid, the motor (43) drives the connecting cylinder (44) to rotate, the stirring blade (45) stirs the molten materials to promote the alloy melting process, the fluid materials are guided by the lubricating body (54) to cast the inside of the molded shell, and the molded shell is cooled to form a high-precision aluminum alloy workpiece.
