[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment: a stamping die for automobile parts, comprising a lower die 1, which can receive the raw material of the parts and stamp it into shape by extrusion, and a buffer component is elastically connected to the upper end of the lower die 1, and the buffer component comprises a buffer column 2, and the buffer column 2 can contact the upper end extrusion device to provide a reaction force to it, so that it can be buffered when it slides down, and the lower part of the buffer column 2 is elastically connected to the inside of the lower die 1 through a spring three 10, and the spring three 10 can squeeze the buffer column 2 to keep it in a sliding state, the upper part of the spring three 10 is in contact with the lower part of the buffer column 2, and the lower part of the spring three 10 is in contact with the inside of the lower die 1, and the spring three 10 is squeezed by the lower die 1 to keep the buffer column 2 in a state of being squeezed, and the spring three 10 is not fixedly connected and can be easily replaced.

[0032] Reference Figure 1-Figure 2A sliding block 6 is fixedly connected to the inside of the side end of the lower mold 1. The sliding block 6 is restricted by the lower mold 1 to slide vertically within a fixed distance, so that the sliding ring 5 can only slide vertically within a fixed distance relative to the lower mold 1. A magnet 7 is fixedly connected to the inside of the sliding block 6. The magnet 7 can be adsorbed with the lower mold 1 to keep the sliding ring 5 from sliding down, so that the clamping rod 3 can be fixed inside the buffer column 2 and remain fixed. The upper and lower parts of the magnet 7 are in contact with the inside of the side end of the lower mold 1, and the side end of the sliding ring 5 slides outside the side end of the lower mold 1. The lower mold 1 restricts the sliding ring 5 to slide vertically. The side end of the sliding block 6 is fixedly connected to the sliding ring 5, and the outside of the sliding ring 5 is fixedly connected to the inclined surface block 4. The upper part of the inclined surface block 4 is an inclined surface, which can squeeze the left end of the clamping rod 3 so that it can slide into the buffer column 2 and remain fixed.

[0033] Reference Figure 1 and Figure 3 The upper end of the inclined plane block 4 is slidably connected to a clamping rod 3, and a square groove is provided at the left end of the clamping rod 3 to facilitate the extrusion and sliding of the inclined plane block 4. The right end of the clamping rod 3 is slidably connected to the inside of the side end of the lower mold 1 and the inside of the side end of the buffer column 2 respectively. The clamping rod 3 is restricted by the lower mold 1 and can only slide horizontally, so that the buffer column 2 cannot slide up and down. In this way, when replacing accessories, the buffer column 2 can block the closure of the extrusion device and the lower mold 1 to prevent pinching. The right side end of the clamping rod 3 is fixedly connected to a clamping block 9, and the clamping block 9 is restricted by the lower mold 1 and can only slide horizontally Moving within a fixed distance can prevent the clamping rod 3 from completely sliding out of the lower mold 1. The left part of the clamping block 9 is elastically connected to the inside of the lower mold 1 through a spring 8. The spring 8 can pull the clamping block 9, so that the clamping block 9 can drive the clamping rod 3 to slide out of the buffer column 2 so that it can slide up and down, which is convenient for stamping. One end of the spring 8 is fixedly connected to the side end of the lower mold 1, and the other end of the spring 8 is fixedly connected to the left part of the clamping block 9. The spring 8 is subjected to the internal pulling force of the lower mold 1 to keep the clamping block 9 in a state, and a gear assembly is fixedly connected to the upper end of the lower mold 1.

[0034] Reference Figure 1 , Figure 3 and Figure 4The gear assembly includes a fixed column 13, which can limit the gear block 11 to slide horizontally only within a fixed distance. The right part of the fixed column 13 is fixedly connected to the upper end of the lower mold 1, and the lower mold 1 can limit the fixed column 13 to remain relatively fixed. The left end of the fixed column 13 is slidably connected to the outside of the gear block 11. The side end of the buffer column 2 is provided with a square groove, which can make the gear block 11 limit the buffer column 2 from sliding out of the lower mold 1 and maintain stability. The right part of the gear block 11 is elastically connected to the upper end of the lower mold 1 through the spring 2 12. The spring 2 12 can squeeze the gear block 11 so that it can be fixed in the square groove at the side end of the buffer column 2 to maintain stability. One end of the spring 2 12 is fixedly connected to the right end of the gear block 11, and the other end of the spring 2 12 is fixedly connected to the upper end of the lower mold 1. The buffer column 2 can slide out by sliding the gear block 11, which makes it convenient to replace the buffer column 2 and the internal spring 3 10. The side end of the gear block 11 is slidably connected to the inside of the buffer column 2.

[0035] Working principle: place the accessory in the middle of the lower mold 1, and stamp the accessory by sliding the extrusion device down. The extrusion device can squeeze the buffer column 2 to slide down. The buffer column 2 slides down and squeezes the spring three 10. The spring three 10 provides a recoil force so that the buffer column 2 buffers the extrusion device. The extrusion device slides up, and the sliding ring 5 slides up. The sliding ring 5 drives the inclined surface block 4 and the sliding block 6 to slide up. The upper inclined surface of the inclined surface block 4 squeezes the left square groove of the clamping rod 3, so that the clamping rod 3 can slide into the lower mold 1. The clamping rod 3 drives the clamping block 9 to slide and pull the spring 8. When the clamping rod 3 slides into the side end of the buffer column 2, the upper part of the inclined surface block 4 completely slides into the square groove. At this time, the upper part of the magnet 7 contacts the inner side end of the lower mold 1 and the upper part of the lower mold 1, so that the sliding block 6 and the sliding ring 5 will not The sliding holding inclined plane block 4 can be fixed inside the clamping rod 3 to keep the buffer column 2 fixed to prevent pinching. When the accessories are taken out, the inclined plane block 4 and the sliding ring 5 can be moved down. The sliding ring 5 drives the sliding block 6 and the magnet 7 to slide down. When the inclined plane block 4 slides out of the square groove of the clamping rod 3, the spring 1 8 pulls the clamping block 9 and the clamping rod 3 to slide out of the buffer column 2 so that they can slide up and down. When the spring 3 10 fails or the buffer column 2 is damaged, the stop block 11 can be slid to slide out of the square groove at the side end of the buffer column 2. The stop block 11 squeezes the spring 2 12, and then the internal buffer column 2 and the spring 3 10 can be slid out for replacement. Then the stop block 11 is released, so that the spring 2 12 squeezes the stop block 11 to slide into the square groove at the side end of the buffer column 2 so that it cannot completely slide out of the lower mold 1.
