A hydraulic rod 23 is connected to the hydraulic cylinder 22. A lifting plate 24 is installed on the bottom side of the hydraulic rod 23. A punch 25 is welded on the bottom side of the lifting plate 24. A circular hole is opened on the lifting plate 24, and the support rod 20 passes through the circular hole. The lifting plate 24 slides with the support rod 20; when working, the existing punching equipment is used in the process of punching aluminum alloy die castings. In the process, the aluminum alloy die-casting that has been punched cannot be quickly unloaded, resulting in low unloading efficiency. The aluminum alloy die-casting is placed in the placement groove 4, and then the hydraulic cylinder 22 is operated, and the hydraulic rod 23 drives the lifting plate 24 to move vertically downward, and the lifting plate 24 drives the punch 25 to move vertically downward.

When the push plate 6 moves upward, it pushes the aluminum alloy die-casting to move upward, so that the aluminum alloy die-casting is taken out from the mold cavity 3. Then the push plate 6 is tilted, and the aluminum alloy die-casting slides obliquely downward along the push plate 6 to the guide plate 26, and then slides out from the guide plate 26, realizing the rapid unloading of the aluminum alloy die-casting. Then the push plate 6 moves downward to return to its original position.

The aluminum alloy die-casting is placed in the placement groove 4, and then the hydraulic cylinder 22 is operated, the hydraulic rod 23 drives the lifting plate 24 to move vertically downward, and the lifting plate 24 drives the punch 25 to move vertically downward. The punch 25 descends and applies force to the aluminum alloy die-casting, and impacts it into the mold cavity 3 of the lower mold 2. As the impact force increases, plastic deformation will also occur while compressing and deforming, so that the surface of the aluminum alloy die-casting produces the desired edge shape, thereby realizing the punching forming of the aluminum alloy die-casting; then the motor 10 is operated to drive the rotating plate 9 to rotate. During the rotation of the rotating plate 9, the first connecting rod 11 is pulled to rotate, and the first connecting rod 11 drives the second connecting rod 12 to move vertically upward and then vertically downward. When 11 drives the second connecting rod 12 to move vertically upward, the second connecting rod 12 drives the push plate 6 to move vertically upward, and the push plate 6 drives the third connecting rod 15 and the fourth connecting rod 19 thereon to move vertically upward until the fixed block 16 on the third connecting rod 15 contacts the positioning ring 17, the fixed block 16 is intercepted by the positioning ring 17, and the third connecting rod 15 is pulled by the positioning ring 17 and cannot continue to move upward, but the second connecting rod 12 continues to drive the push plate 6 to continue to move upward, so that the push plate 6 is in an inclined state, and when the push plate 6 moves upward, it pushes the aluminum alloy die-casting to move upward, so that the aluminum alloy die-casting is taken out from the mold cavity 3, and then the push plate 6 is tilted, and the aluminum alloy die-casting slides obliquely downward along the push plate 6 to the guide plate 26, and then slides out from the guide plate 26, realizing the rapid unloading of the aluminum alloy die-casting, and then the push plate 6 moves downward to return to its original position.
