[0015] By adopting the above technical solution, the upper and lower molds and the stamping equipment can be easily disassembled and assembled through the upper fixing feet installed on the upper fixing plate and the lower fixing feet installed on the lower fixing plate.

[0016] Preferably, the slide groove is a circular channel, and the slider is a circular plate.

[0017] Preferably, the diameter of the sliding block is larger than the diameter of the top opening end of the lower guide cylinder.

[0018] Compared with the prior art, the beneficial effect of the utility model is that it can play a dust-proof role on the slide grooves opened on the upper guide rod and the lower guide cylinder, preventing dust and waste chips generated by stamping from entering the slide grooves and affecting the sliding of the upper guide rod in the slide grooves, thereby avoiding affecting the use of the guide device, and further improving the accuracy of mold closing and the quality of the product.

The hydraulic press of the stamping equipment drives the upper mold 3 to move downward and close the mold with the lower mold 6. When the upper fixed plate 1 moves downward, it drives the slider 14 installed at the bottom end of the upper guide rod 7 to slide in the slide groove 9 opened on the lower guide cylinder 8, which plays a role in guiding the upper and lower molds. When the upper guide rod 7 and the lower guide cylinder 8 slide and guide, the elastic bellows 11 installed on the outside of the upper guide rod 7 and the open end of the lower guide cylinder 8 are retracted, which can play a dust-proof role for the slide groove 9 opened on the upper guide rod 7 and the lower guide cylinder 8, and prevent dust and waste chips generated by stamping from entering the slide groove 9 and affecting the sliding of the upper guide rod 7 in the slide groove 9, thereby avoiding affecting the use of the guide device, thereby improving the accuracy of mold closing and the quality of the product.

[0026] Refer to Figure 2. Figure 3 , Figure 4 A spring 10 is installed between the bottom of the slider 14 and the slide groove 9. When the slider 14 moves in the slide groove 9, it will squeeze the spring 10, which can buffer the downward pressing speed of the upper mold 3. The protrusion installed on the slider 14 is slidably connected with the track opened on the wall of the slide groove 9. When the slider 14 moves in the slide groove 9, the mating protrusion also slides in the track, which increases the stability of the slider 14 during guidance and makes the mold closing more precise.
