Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0019] The present invention provides the following embodiments Example 1 The embodiment of the present invention provides a 7050 aluminum alloy ingot casting method and device, such as Figure 1-5 As shown, the method includes the following steps: Step 1: convey the lower mold 15 to the bottom of the upper mold installation mechanism 12 through the lower mold conveyor belt 14, and preheat the lower mold 15 through the lower mold conveyor belt 14; Step 2: Place the upper mold 13 in the upper mold installation mechanism 12 by a robot and clamp and install it; Step 3: The installed upper mold 13 is turned 180 degrees by the upper mold turning and regulating assembly 11, and then moves vertically downward to cooperate with the lower mold 15, and is fastened by the fastening mechanism 16; Step 4: preparing 7050 aluminum alloy melt, performing melt purification on the 7050 aluminum alloy melt, and introducing the 7050 aluminum alloy melt after the melt purification into the liquid storage tank 170; Step 5: introducing the 7050 aluminum alloy melt in the liquid storage tank 170 into the lower mold 15, and continuously exhausting the introduced 7050 aluminum alloy melt during the process; Step 6. After the 7050 aluminum alloy melt is introduced, the upper mold flipping and regulating component 11 lifts the upper mold 13 and the lower mold 15 at the same time, flips them in the air and returns them to their original positions, and then vents them again. After the venting is completed, the temperature and flow rate of the cooling medium in the cooling nozzle 174 are adjusted to control the cooling rate of the 7050 aluminum alloy melt, thereby achieving precise control of the ingot structure.

[0020] Among them, the composition of the 7050 aluminum alloy melt includes mass fractions of Al (6.4%-6.7%), Zn (2.4%-2.6%), Mg (2.0%-2.2%), Cu (<0.08%), Zr (<0.1%), Fe (<0.06%), Si (<0.12%), Mn (<0.04%), and Cr (<0.06%); Melt purity control is achieved through melt purification treatment, which removes oxides, hydrogen and other impurities in the original 7050 aluminum alloy melt. The melt purification treatment includes the use of vacuum melting, argon protection, refining treatment and fluid filtration to treat the original 7050 aluminum alloy melt to ensure the purity of the aluminum alloy melt, avoid the influence of impurities and gases, reduce bubbles and inclusions inside the ingot, and improve the density and mechanical properties of the ingot; Microstructure control: By regulating the cooling rate and exhaust process of the 7050 aluminum alloy melt, the microstructure grains are prevented from being too coarse or having microstructure defects, so that the ingot has a uniform microstructure, the grains are refined, the pores and inclusions are reduced, and the tensile strength, fatigue resistance and corrosion resistance are improved. Preferably, the 7050 aluminum alloy ingot needs to undergo a heat treatment process after casting to improve its microstructure and enhance its performance. The heat treatment process includes aging treatment (which can significantly improve the strength and hardness of the aluminum alloy) and ingot surface treatment (such as sandblasting, pickling, etc., which help improve surface quality).

[0025] The working principle and beneficial effects of the above technical solution are as follows: the height electric adjustment screw 110 rotates to drive the height adjustment nut 111 to move up and down, thereby driving the back plate 112 to move up and down, thereby driving the upper mold installation mechanism 12 or the upper mold 13 to move up and down; The rotating driving gear 115 rotates and cooperates with the annular rack 116 to drive the electric telescopic column 113 to rotate, thereby realizing the flipping of the upper mold installation mechanism 12 or the upper mold 13. The electric telescopic column 113 can be extended and retracted to adjust the horizontal spatial position of the upper mold installation mechanism 12 or the upper mold 13, thereby improving the flexibility of the device.

A cooling nozzle 174 is provided on the baffle 173.

[0032] The working principle and beneficial effects of the above technical solution are as follows: when adding liquid, the telescopic hard tube 172 extends to the liquid inlet 152 of the lower mold body 150, and the 7050 aluminum alloy melt is introduced into the mold through the liquid storage tank 170 and the telescopic hard tube 172.

During the whole process, the receiving plate 1206 moves upward to receive the upper mold 13. When the upper mold 13 passes through the installation hole 1212 and is placed on the receiving plate 1206, the electric spindle 1200 rotates to drive the receiving plate 1206 to move downward.

If the gap between the upper mold 13 and the mounting hole 1212 is too large, as the electric spindle 1200 rotates to drive the receiving plate 1206 to move downward, the electric spindle 1200 drives pulley 1 123 to rotate, pulley 1 123 drives transmission belt 125 to transmit, transmission belt 125 drives pulley 2 124 to rotate, pulley 2 124 drives the driven screw 122 to rotate, the driven screw 122 drives the clamping nut 126 to move, and the clamping nut 126 drives the retractable arc pressure block 127 to move toward the upper mold 13, so that the retractable arc pressure block 127 cooperates with the wedge-shaped block 1210 to clamp the upper mold 13.
