[0027] In some examples, the buffer assembly 5 includes a mounting groove 51, a mounting seat 52, a cross plate 53, a first slide groove 54, a through hole 55 and a connecting rod 56. The mounting groove 51 is opened on both sides of the top of the lower mold base 1, the mounting seat 52 is movably connected to the mounting groove 51, the cross plate 53 is movably connected to the top of the mounting seat 52, the first slide groove 54 is opened inside the mounting seat 52, the through hole 55 passes through the top inner wall of the first slide groove 54 and has a diameter smaller than the first slide groove 54, and the top end of the connecting rod 56 is fixedly connected to the cross plate 53 and the bottom end passes through the through hole 55 and extends to the inside of the first slide groove 54.

[0028] In some examples, the buffer assembly 5 also includes a first slider 57 and a first spring 58. The first slider 57 is fixedly connected to the bottom end of the connecting rod 56 and is slidably connected to the first slide groove 54. The first spring 58 is fixedly installed inside the first slide groove 54 and its two ends are respectively fixedly connected to the bottom of the first slider 57 and the inner wall of the bottom of the first slide groove 54. When the upper mold base 2 moves downward, the cross bar will press downward. At this time, the cross bar will drive the first slider 57 to move downward along the first slide groove 54 through the connecting rod 56 and squeeze the first spring 58. The rebound force generated by the first spring 58 will buffer the upper mold base 2 and reduce the impact force generated when the stamping block contacts the auto parts, effectively avoiding damage caused by rapid contact between the stamping block and the auto parts.

[0029] In some examples, the buffer assembly 5 also includes an empty slot 59 and a top block 510. The empty slot 59 is opened on both sides of the placement frame 4. The top block 510 is fixedly connected to the inner side of the cross bar and is adapted to the size of the empty slot 59. When the cross bar moves downward, it will drive the top block 510 to move downward along the empty slot 59 until it is immersed in the empty slot 59. When the stamping is completed, the upper mold moves upward. At this time, the first spring 58 rebounds and drives the cross bar to move upward through the first slider 57 and the connecting rod 56. The cross bar drives the top block 510 to move upward, thereby ejecting the stamped automobile parts upward.

[0030] In some examples, the mounting assembly 6 includes a mounting hole 61, a connecting groove 62 and a mounting rod 63. The mounting hole 61 passes through the bottom of the mounting seat 52 and is below the first slide groove 54. The connecting groove 62 is opened inside the lower mold base 1 and is connected to the mounting groove 51. The mounting rod 63 is movably connected to the connecting groove 62 and is adapted to the size of the mounting hole 61. The mounting seat 52 is placed in the mounting groove 51, and then the mounting rod 63 is inserted into the mounting hole 61 to fix the mounting seat 52 in the mounting groove 51, thereby completing the installation of the buffer assembly 5.

[0031] In some examples, the mounting assembly 6 also includes a second slide groove 64, a second slider 65, a second spring 66 and a pull rod 67. The second slide groove 64 is opened at the top of the lower mold base 1 and is connected to the connecting groove 62. The second slider 65 is fixedly connected to one end of the mounting rod 63 and is slidably connected to the second slide groove 64. The second spring 66 is fixedly installed inside the second slide groove 64 and its two ends are respectively fixedly connected to one side of the second slider 65 and the inner wall of one side of the second slide groove 64. The pull rod 67 is fixedly connected to the top of the second slider 65. Pulling the pull rod 67 outward can drive the mounting rod 63 to move outward through the second slider 65 and squeeze the second spring 66. Release the pull rod 67, the second spring 66 rebounds and can drive the mounting rod 63 to move inward through the second slider 65.

[0032] In a specific application scenario, first pull the pull rod 67 outward so that it drives the mounting rod 63 to move outward through the second slider 65 and squeezes the second spring 66. When the mounting rod 63 moves out of the mounting slot 51, the mounting seat 52 is placed in the mounting slot 51 and the mounting hole 61 and the mounting rod 63 are on the same axis. Then release the pull rod 67, the second spring 66 rebounds and drives the mounting rod 63 to move inward through the second slider 65. When the mounting rod 63 is inserted into the mounting hole 61, the mounting seat 52 can be fixed in the mounting slot 51, thereby completing the installation of the buffer assembly 5. Then, place the parts to be stamped on the top of the top block 510 above the placement frame 4. At this time, start the mold so that it drives the stamping block to move downward through the upper mold base 2. When the stamping block When in contact with the parts, the parts are subjected to pressure and drive the top block 510 to move downward along the empty slot 59. The top block 510 drives the first slider 57 to slide downward along the first slide slot 54 through the cross bar and the connecting rod 56 and squeezes the first spring 58. At this time, the rebound force generated by the first spring 58 will buffer the impact force generated when the stamping block contacts the parts. Then the stamping block continues to move downward to stamp the parts. After the stamping is completed, the upper die seat 2 drives the stamping block to move upward. At this time, the first spring 58 rebounds and drives the cross bar to move upward through the first slider 57 and the connecting rod 56. The cross bar drives the top block 510 to move upward along the empty slot 59, thereby ejecting the stamped parts upward. At this time, the staff can take it out of the stamping slot 3.

[0033] By adopting the above technical solution: not only can the impact force generated when the punching block contacts the parts be buffered, effectively avoiding damage to the mold caused by excessive impact force due to too fast contact, but also the parts can be ejected from the punching groove after the punching is completed, so that the staff can take out the parts more quickly, and the installation and disassembly of the buffer assembly is also relatively simple and quick, effectively improving work efficiency.

[0034] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the present invention.
