[0029] Specifically, the hydraulic rod 401 moves the upper mold 402 downward and bends the aluminum alloy door and window workpiece. After bending, the workpiece is rotated by the drive shaft 502 through the motor 505, and the lower mold 503 is rotated, so that the workpiece unloading operation can be completed quickly and the unloading efficiency is improved. When the lower mold 503 is reset, the square hole 501 can be used for positioning operation to accurately reset the lower mold 503.

[0030] Example 2

[0031] See Figure 4 , and on the basis of Example 1, it is further obtained that the pop-up mechanism 6 includes a square groove 601 opened at the top of the lower mold 503, the bottom end of the square groove 601 is fixedly connected to multiple springs 602, the top of the multiple springs 602 is fixedly connected to a curved plate 605, and limiting grooves 603 are opened at both ends of the square groove 601, and limiting blocks 604 are set on the inner walls of the two limiting grooves 603, and the two limiting blocks 604 are fixedly connected to the curved plate 605.

After bending, the upper mold 402 is moved upward, and the limiting groove 603 is moved upward under the elastic return action of the spring 602 to prevent the workpiece from being stuck in the square groove 601, thereby facilitating the material removal operation of the workpiece.

[0040] Then, the electric push rod 702 is started to move the clamping column 703 outward, so that it leaves the range of the clamping slot 704. Then, the motor 505 is started to rotate the driving shaft 502, thereby rotating the lower mold 503 and turning it 180 degrees, thereby facilitating the unloading operation of the workpiece and improving the unloading efficiency.
