When the automobile bracket needs to be ejected after punching, the electric cylinder 7 can be controlled to extend and push the waste cleaning plate 8 to slide to the far right. At this time, the ejector plate 12 will move to the right, so the ejector plate 12 can push the automobile bracket outward through the opening on the right side of the lower mold 2, thereby easily completing the unloading. ;

[0030] In the present disclosure, Figure 2 and Figure 4 As shown, a rectangular notch groove is provided on the left side of the workpiece groove at the top of the lower mold 2, and the cross-sectional size of the rectangular notch groove is equal to the cross-sectional size of the ejector plate 12. When it is necessary to punch the automobile bracket, the electric cylinder 7 can be controlled to contract to drive the waste cleaning plate 8 to slide to the far left. At this time, the waste cleaning plate 8 will drive the ejector plate 12 to slide to the far left through the ejector plate support rod 11 and embed into the rectangular notch groove on the left side of the workpiece groove at the top of the lower mold 2, so as not to hinder the placement of the automobile bracket.

[0031] In the present disclosure, Figure 2 and Figure 4 As shown, the right side of the workpiece slot at the top of the lower mold 2 is an open structure, and when the waste cleaning plate 8 slides to the extreme left, the left outer wall of the side baffle 10 will be tightly attached to the right outer wall of the lower mold 2 and close the opening. When it is necessary to punch the automobile bracket, the electric cylinder 7 can be controlled to contract to drive the waste cleaning plate 8 to slide to the extreme left. At this time, the waste cleaning plate 8 will drive the side baffle 10 to slide to the extreme left through the baffle support rod 9 and close the opening on the right side of the workpiece slot at the top of the lower mold 2, so the automobile bracket can be prevented from moving left and right during the stamping process. When the automobile bracket needs to be ejected, it can slide out through the opening on the right side of the workpiece slot at the top of the lower mold 2.

[0032] In the present disclosure, Figure 2-Figure 5 As shown, when the waste cleaning plate 8 slides to the extreme left, the ejector plate 12 will be embedded in the rectangular notch groove on the left side of the workpiece groove at the top of the lower mold 2. When the waste cleaning plate 8 slides to the extreme right, the ejector plate 12 will be located at the right edge of the workpiece groove at the top of the lower mold 2. When it is necessary to punch the automobile bracket, the electric cylinder 7 can be controlled to contract to drive the waste cleaning plate 8 to slide to the extreme left. At this time, the waste cleaning plate 8 will drive the ejector plate 12 to slide to the extreme left through the ejector plate support rod 11 and embed it in the rectangular notch groove on the left side of the workpiece groove at the top of the lower mold 2, so that it will not hinder the placement of the automobile bracket. After the punching is completed, when the automobile bracket needs to be ejected, the electric cylinder 7 can be controlled to extend and push the waste cleaning plate 8 to slide to the extreme right. At this time, the side baffle 10 and the ejector plate 12 will both move to the right, so the ejector plate 12 can push the automobile bracket outward through the opening on the right side of the lower mold 2, thereby easily completing the blanking.

[0033] In the present disclosure, Figure 1-Figure 5As shown, a rectangular groove with openings on both sides is provided at the bottom of the lower mold 2, and the outer wall of the waste cleaning plate 8 is in close contact with the inner wall of the rectangular groove and can slide left and right inside it. The waste generated during punching will fall into the rectangular groove at the bottom of the lower mold 2. When the automobile bracket needs to be ejected after the punching is completed, the electric cylinder 7 can be controlled to extend and push the waste cleaning plate 8 to slide to the far right. At this time, the waste cleaning plate 8 will push the waste in the rectangular groove at the bottom of the lower mold 2 to the right to avoid excessive accumulation of waste and affect subsequent punching.

[0034] In the present disclosure, Figure 4-Figure 6 As shown, a long strip groove running through the top of the lower die base 1 is provided, and the cross bar at the bottom of the baffle support rod 9 is embedded in the long strip groove and can slide left and right inside it, so the cross bar at the bottom of the baffle support rod 9 will not protrude downward, and the waste generated during punching is more likely to fall into the rectangular groove at the bottom of the lower die 2.

[0035] Embodiment 2, based on embodiment 1, as Figure 1-Figure 6 As shown, the ejector plate support rod 11 is a C-shaped rod. When the waste cleaning plate 8 slides to the far right, the vertical rod part of the ejector plate support rod 11 will be located on the left side of the lower mold 2. Because the waste cleaning plate 8 can adjust the position of the ejector plate 12 through the ejector plate support rod 11 when sliding left and right, the waste cleaning plate 8 can be pushed to slide to the far right after punching is completed. At this time, the ejector plate 12 will move to the right to push the car bracket outward through the opening on the right side of the lower mold 2, and the ejector plate support rod 11 will not collide with the lower mold 2 to cause conflict.

[0036] The working principle of this embodiment is as follows: during installation, the position of the lower die base 1 is first fixed and the top of the upper die base 4 is connected to the bottom end of the external hydraulic cylinder, so that the upper die base 4 can be pushed up and down, and then the electric cylinder 7 on the top of the electric cylinder support plate 6 can be connected to the external controller and power supply;

[0037] When it is necessary to punch the automobile bracket, the upper die seat 4 can be driven by the hydraulic cylinder to slide up to the top under the support of the column 3, and then the electric cylinder 7 can be controlled to contract to drive the waste cleaning plate 8 to slide to the leftmost side. At this time, the waste cleaning plate 8 will drive the side baffle plate 10 to slide to the leftmost side through the baffle support rod 9 and close the opening on the right side of the workpiece slot at the top of the lower mold 2, so the automobile bracket can be prevented from moving left and right during the stamping process. In addition, the waste cleaning plate 8 will also drive the ejector plate 12 to slide to the leftmost side through the ejector plate support rod 11 and embed it into the rectangular notch groove on the left side of the workpiece slot at the top of the lower mold 2. At this time, the automobile bracket can be placed in the workpiece slot at the top of the lower mold 2, and then driven by the hydraulic cylinder. The upper die base 4 moves down to close the die. During the closing process, the die rod 5 cooperates with the lower die 2 to punch the automobile bracket, and the waste generated during punching will fall into the rectangular groove at the bottom of the lower die 2. After the punching is completed, the upper die base 4 is driven by the hydraulic cylinder to slide up to the top under the support of the column 3, and then the electric cylinder 7 is controlled to extend and push the waste cleaning plate 8 to slide to the far right. At this time, the side baffle 10 and the ejector plate 12 will both move to the right, so the ejector plate 12 can push the automobile bracket outward through the opening on the right side of the lower die 2, thereby easily completing the unloading. At the same time, the waste cleaning plate 8 will also push the waste in the rectangular groove at the bottom of the lower die 2 to the right to avoid excessive waste accumulation and affect subsequent punching.
