[0002] In the automotive manufacturing industry, die ejection is an indispensable part of the stamping process. Die ejection refers to the rapid and accurate removal of the workpiece from the die after stamping, allowing for further processing or handling. This process plays a crucial role in improving production efficiency and ensuring product quality. With the rapid development of the automotive industry, higher demands are placed on die ejection technology. Not only is high ejection speed and precision required, but the device structure must also be simple and easy to maintain to meet the needs of modern production lines. Therefore, developing a high-efficiency and stable die ejection device for automotive stamping is particularly important.

[0003] Traditional blanking and unloading devices have several drawbacks in practical applications. Firstly, their complex structures involve the coordinated operation of multiple components, increasing both manufacturing difficulty and maintenance costs. Over extended periods, this complex structure can lead to frequent malfunctions, impacting production line stability. Secondly, the unloading accuracy and speed of traditional devices fail to meet the high demands of modern automotive manufacturing. Insufficient fit between components or unstable transmission methods can cause deviations during unloading, affecting workpiece quality. Furthermore, traditional devices lack adaptability; complex adjustments or modifications are often required for workpieces of different shapes and sizes, reducing production line flexibility. Therefore, there is an urgent need to develop a novel blanking and unloading device for automotive stamping dies to address the problems of traditional technologies and meet the development needs of modern automotive manufacturing. To this end, we propose a blanking and unloading device for automotive stamping dies. Utility Model Content

[0022] Please see Figure 1-3A flipping and unloading device for an automotive stamping die includes a worktable 1, with an unloading component fixedly connected to the bottom of the inner wall of the worktable 1.

[0023] The unloading assembly includes a reset spring seat 2, which is fixedly connected to the bottom of the inner wall of the worktable 1. A rack 3 is fixedly connected to the top of the reset spring seat 2, and the rack 3 is perpendicular to the bottom of the inner wall of the worktable 1. A slide rail 4 is fixedly connected to one side of the top of the worktable 1. A limit slide 5 is fixedly connected to the outer wall of one side of the rack 3, and the limit slide 5 is slidably connected to the outer wall of one side of the slide rail 4. A gear 6 is movably connected to the inner wall of one end of the worktable 1, and one side of the gear 6 is meshed with the outer wall of the rack 3 away from the slide rail 4. A limit track seat 7 is fixedly connected to the bottom of the inner wall of the worktable 1. A second rack 8 is slidably connected to both ends of the inner wall of the limit track seat 7, and the second rack 8 is parallel to the rack 3. One side of the outer wall of the second rack 8 is meshed with the outer wall of the gear 6 away from the rack 3. Through the transmission mechanism of the rack, gear, and second rack, the unloading top column can move up and down, providing power for the unloading action.

[0024] Furthermore, a top plate 9 is fixedly connected to the top of the second rack 8, and four ejector pins 10 distributed in a rectangular shape are fixedly connected to the top of the top plate 9. The fixed connection between the top plate and the ejector pins ensures that the ejector pins can stably eject the workpiece and achieve the ejection effect.

[0025] Furthermore, the top of the rack 3 extends to the top of the worktable 1, and the top two sides of the worktable 1 are fixedly connected to the fixing brackets 14. The extension design of the rack facilitates the connection of the telescopic rod, while the fixing brackets provide stable support for the telescopic rod and the hydraulic rod.

[0026] Furthermore, a telescopic rod 11 is fixedly connected to one side of the top of the inner wall of the fixed frame 14. The bottom output end of the telescopic rod 11 is in frictional contact with the top of the rack 3. The extension and retraction of the telescopic rod pushes the rack to move up and down, thereby triggering the entire material ejection mechanism.

[0027] Furthermore, a stamping die 12 is fixedly connected to the top of the worktable 1 near the rack 3. Four rectangular, equidistant ejection holes 13 are provided on the bottom of the inner wall of the stamping die 12. The ejection holes 13 are parallel to the ejection pins 10, and the cross-sectional radius of the ejection pins 10 is three-quarters of the cross-sectional radius of the ejection holes 13. The design of the ejection holes of the stamping die, in conjunction with the ejection pins, ensures that the workpiece can be accurately ejected from the die.

[0028] Furthermore, a hydraulic rod 15 is fixedly connected to the top of the inner wall of the fixed frame 14 near the telescopic rod 11. A stamping head 16 is fixedly connected to the bottom output end of the hydraulic rod 15. The bottom output end of the stamping head 16 is located directly above the stamping die 12. The hydraulic rod extends out and drives the stamping head to stamp the workpiece, which is the main power source for the device.

[0029] Furthermore, the bottom of the workbench 1 is fixedly connected with four rectangularly equidistant support legs 17, which provide stable support for the entire device and ensure the stability and safety of the device during operation.

[0049] Working Principle: First, the core of the device lies in the design of the ejection assembly, which consists of a return spring seat 2, a rack 3, a slide rail 4, a limiting slide bar 5, a gear 6, a limiting track seat 7, and a second rack 8. When the device starts working, the hydraulic rod 15 extends, driving the stamping head 16 to move downwards to stamp the workpiece within the stamping die 12. At this time, the rack 3 is in its initial position, and the ejection top post 10 is not in contact with the workpiece. During the stamping process, in preparation for the ejection action, the telescopic rod 11 (located at the top of the inner wall of the fixed frame 14) begins to extend, pushing the rack 3 downwards in a direction perpendicular to the bottom of the inner wall of the worktable 1. The movement of the rack 3 is stably guided by the sliding of the limiting slide bar 5 on the slide rail 4. Simultaneously, the downward movement of the rack 3 drives the gear 6 meshing with it to rotate, and the rotation of the gear 6 further drives the second rack 8 meshing with it on the other side to slide on the inner wall of the limiting track seat 7. Since the second rack 8 is parallel to the rack 3 and moves in opposite directions, the upward movement of the second rack 8 causes the top plate 9, which is fixedly connected to the top, and the four ejector pins 10 to rise together. After the stamping process is completed, the hydraulic rod 15 retracts and the stamping head 16 is raised. At this time, the telescopic rod 11 also stops extending, and the return spring seat 2 exerts its elasticity to push the rack 3 to return to its original position. The return of the rack 3 is then transmitted to the second rack 8 through the gear 6, causing it to move downward, which in turn causes the top plate 9 and the ejector pins 10 to descend. During the descent of the ejector pins 10, their tops gradually contact and pass through the ejection hole 13 at the bottom of the stamping die 12, ejecting the processed workpiece from the die and achieving the ejection effect. The entire ejection process is smooth and efficient, and the elasticity of the return spring seat 2 ensures that the device can automatically return to its original position after ejection, preparing for the next stamping process.
