[0019] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —4: A stamping die for edge banding of inner and outer panels of a car tailgate includes a lower die base 1 and a material support frame 2. A fixed plate 3 is provided vertically below the material support frame 2. A lower die material support cylinder 4 and a support 5 are provided on the side of the fixed plate 3 and installed in the lower die base 1. The piston rod of the lower die material support cylinder 4 faces the fixed plate 3. A linkage rod 6 is hinged to the support 5. The linkage rod 6 includes a first connecting rod 6a and a second connecting rod 6b fixedly connected at their ends. The other end of the first connecting rod 6a is connected to the fixed plate 3, and the other end of the second connecting rod 6b is connected to the piston rod of the lower die material support cylinder 4. When the piston rod of the lower die material support cylinder 4 extends or retracts, it drives the linkage rod 6 to rotate around the hinge axis between it and the support 5. The movement of the first connecting rod 6a drives the fixed plate 3 to move vertically.

[0020] The working principle of this utility model is as follows: Figure 1-3 As shown, when the piston rod of the lower mold support cylinder 4 extends, it drives the linkage rod 6 to rotate clockwise around its hinge axis with the support 5, thereby causing the fixed plate 3 to move downwards, as shown. Figure 2 As shown; when the piston rod of the lower mold support cylinder 4 retracts, it drives the linkage rod 6 to rotate counterclockwise around its hinge axis with the support 5, thereby driving the fixed plate 3 to move upward, as shown. Figure 3 As shown.

[0021] This invention features a lower mold support cylinder 4 mounted on the side of a fixed plate 3, with the piston rod of the lower mold support cylinder 4 facing the fixed plate 3. The fixed plate 3 and the lower mold support cylinder 4 are connected by a linkage rod 6, thereby ensuring that the extension and retraction direction of the piston rod of the lower mold support cylinder 4 is not vertical. This effectively shortens the vertical space required for the lower mold support cylinder 4 and its stroke, making it suitable for lower mold bases 1 and lower mold cutter blocks with lower heights. When it is necessary to apply it to lower mold bases 1 and lower mold cutter blocks with higher heights, the length of the fixed plate 3 can be increased, resulting in a wide range of applications.

[0022] The specific installation structure of the lower mold material support cylinder 4, the linkage rod 6, and the fixing plate 3 is as follows: A mounting base 7 is fixedly installed inside the lower mold base 1. The lower mold material support cylinder 4 is hinged to the mounting base 7. The piston rod of the lower mold material support cylinder 4 is hinged to the end of the connecting rod 6b away from the connecting rod 6a. The fixing plate 3 is provided with an oblong hole 8, the length direction of which is vertically arranged. The end of the connecting rod 6a away from the connecting rod 6b is provided with a pin 9, which slides in the oblong hole 8. The connecting rod 6a is connected to the fixing plate 3 through the pin 9. The structure is simple and easy to process and install.

[0023] This invention uses a lower mold material support cylinder 4 hinged to a mounting base 7 to achieve displacement of the end of connecting rod 2 6b away from connecting rod 1 6a in both vertical and horizontal directions, while the piston rod of the lower mold material support cylinder 4 moves in a straight line.

[0024] This invention achieves the connection of the end of the connecting rod 6a away from the connecting rod 6b in both vertical and horizontal directions by means of the pin 9 sliding in the waist-shaped hole 8, while the fixing plate 3 only moves vertically.

[0025] To facilitate the installation of the linkage rod 6, a connecting block 10 is provided on the piston rod of the lower mold material support cylinder 4. The end of the second connecting rod 6b away from the first connecting rod 6a is hinged to the connecting block 10. A connecting plate 6c is provided at the end of the first connecting rod 6a and the second connecting rod 6b that are fixedly connected. The connecting plate 6c is hinged to the support 5.

[0026] To ensure a secure and reliable connection of the linkage rod 6 and to reduce assembly steps, the first linkage 6a, the second linkage 6b, and the connecting plate 6c are an integral structure.

[0027] Furthermore, the support 5 is fixedly installed inside the lower mold base 1, and the support 5 is located below the lower mold material support cylinder 4.

[0028] The specific structure of the material support frame 2: The material support frame 2 includes a horizontally arranged flat plate 2a, a guide sleeve 2b arranged below the flat plate 2a, and an extension plate 2c arranged on the flat plate 2a. The upper end of the fixed plate 3 is fixedly installed in the middle of the flat plate 2a. There are two or more guide sleeves 2b, which are symmetrically distributed on both sides of the fixed plate 3. The extension plate 2c is Z-shaped, and the upper plate of the extension plate 2c is connected to the lower part of the flat plate 2a. The lower plates of the flat plate 2a and the extension plate 2c are provided with support columns 11 to better support the inner and outer panels of the car tailgate.

[0029] The guide sleeve 2b is slidably mounted on the guide post set on the lower mold base 1 to guide the vertical movement of the material support 2, so as to ensure that the material support 2 moves vertically.

[0030] Preferably, there are two or more extension plates 2c, symmetrically distributed on both sides of the fixed plate 3, and two or more support columns 11 are symmetrically arranged on the flat plate 2a. In this embodiment, there are two extension plates 2c, symmetrically distributed on both sides of the fixed plate 3, two support columns 11 are symmetrically arranged on the flat plate 2a, and two guide sleeves 2b, symmetrically distributed on both sides of the fixed plate 3.

[0031] To facilitate automatic loading and unloading and reduce the labor intensity of operators, the lower mold base 1 is equipped with a loading device, a unloading device, and a conveying device. The loading device and the unloading device are both two oppositely arranged conveyor belts 12, and the conveying device is two oppositely arranged conveyor belts 13. The lower mold base 1 is hinged with two brackets 14 and two bracket cylinders 15. The piston rod of the bracket cylinder 15 is hinged to the corresponding bracket 14 and drives the bracket 14 to rotate around its hinge axis with the lower mold base 1. The second conveyor belt 13 is arranged on the corresponding bracket 14.

[0032] The inner and outer panels of the car tailgate are placed on conveyor belt 12 at the loading station. Conveyor belt 12 moves the inner and outer panels forward to conveyor belt 13. After conveyor belts 12 and 13 work together to move the inner and outer panels into position, the lower mold support cylinder 4 drives the support frame 2 to move upward. Under the drive of the bracket cylinder 15, conveyor belt 13 rotates outward around the hinge axis between the bracket 14 and the lower mold base 1. After the lower mold support cylinder 4 drives the support frame 2 to move downward into position, the upper mold base 16 moves downward. After the hemming is completed, the lower mold material support cylinder 4 drives the material support frame 2 to move upward, which in turn drives the inner and outer panels of the car tailgate to move upward. Then, under the drive of the bracket cylinder 15, the second conveyor belt 13 rotates and resets around the hinge axis between the bracket 14 and the lower mold base 1. Immediately afterwards, the lower mold material support cylinder 4 drives the material support frame 2 to move downward, and the inner and outer panels of the car tailgate fall on the second conveyor belt 13. The second conveyor belt 13 drives the inner and outer panels of the car tailgate to move to the first conveyor belt 12 of the unloading station. The first conveyor belt 12 and the second conveyor belt 13 of the unloading station work together to move the inner and outer panels of the car tailgate out.

[0033] When the robotic arm is used for material feeding, conveyor belt 12 and conveyor belt 23 are not working, and conveyor belt 23 is always on the outside. The robotic arm moves the inner and outer panels of the car tail door to be edged onto the material support frame 2. After the lower mold material support cylinder 4 drives the material support frame 2 to move down into place, the upper mold base 16 moves down to perform edge binding. After the edge binding is completed, the lower mold material support cylinder 4 drives the material support frame 2 to move up, thereby driving the inner and outer panels of the car tail door to move up, and the robotic arm removes the inner and outer panels of the car tail door.

[0034] This invention can be used for both manual and robotic loading.

[0035] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
