[0026] A kind of servo hot press lower pressure buffer subassembly, including base 1, fixed seat 2 is set to the top end of base 1, lower mold 3 and upper mold 4 are sequentially set to the upper end of fixed seat 2, flange 17 is set to the middle top end of upper mold 4, hot press plate 5 is set to the same side of upper mold 4 and lower mold 3;Between fixed seat 2 and lower mold 3, damping mechanism is set, damping mechanism includes connecting rod one 9 and connecting rod two 10, two cross-arranged connecting rod one 9 are set to the two sides bottom end of lower mold 3, two cross-arranged connecting rod two 10 are set to the two sides top end of fixed seat 2, connecting rod one 9 and connecting rod two 10 are movably connected, damping mechanism further includes movable slot 11, movable slot 11 is opened to the upper end of lower mold 3, spring damper 12 is set to the left side both ends of movable slot 11, shaft support 13 is set to the output shaft end of spring damper 12, one end of connecting rod two 10 away from connecting rod one 9 and shaft support 13 movably connected;

[0027] In the embodiment, by setting damping mechanism between fixed seat 2 and lower mold 3, the impact force generated in the process of pressing down can be effectively absorbed and consumed by the cooperation of connecting rod one 9, connecting rod two 10 and spring damper 12, avoiding the rigid collision of lower mold 3 and upper mold 4, not only protecting hot press plate 5, but also greatly improving the stability of hot pressing, thereby improving product quality and prolonging the service life of mold.

[0028] As Figure 2 and Figure 4As shown, vertical posts 6 are arranged at four corners of the fixed seat 2, movable sleeves one 7 are arranged at four corners of the upper die 4 and match the vertical posts 6, movable sleeves two 8 are arranged at four corners of the lower die 3 and match the vertical posts 6, an adjusting mechanism is arranged below the movable sleeves two 8 and the vertical posts 6, the adjusting mechanism comprises a threaded groove 14, the threaded groove 14 is arranged at the bottom end of the vertical post 6, a magnetic ring two 15 is threadedly connected outside the threaded groove 14, a magnetic ring one 16 is arranged at the bottom end of the movable sleeve two 8 and movably connected with the vertical post 6, and the magnetic poles of the magnetic ring one 16 and the magnetic ring two 15 on the same side are the same;

[0029] In the embodiment, the adjusting mechanism is arranged below the movable sleeves two 8 and the vertical posts 6, the repulsive force of the magnetic poles of the magnetic ring one 16 and the magnetic ring two 15 and the cooperation of the threaded groove 14 are utilized to realize flexible and accurate fine adjustment of the height of the lower die 3, quickly adapt to the requirement of different hot pressing processes on the hot pressing gap between the upper die 4 and the lower die 3, effectively solve the deficiencies of the hot press in the aspects of buffering and damping and height adjustment in the prior art, and improve the production efficiency and the stability of product quality.

[0030] Working principle: when the servo hot press drives the upper die 4 to move downward, the lower die 3 will be subjected to downward pressure. At this time, the connecting rod one 9 arranged at the bottom end of the lower die 3 will move due to the downward movement of the lower die 3, and then drive the connecting rod two 10 movably connected therewith to move. The end of the connecting rod two 10 away from the connecting rod one 9 is movably connected with the shaft bracket 13 of the output shaft end of the spring damper 12 in the movable groove 11, so that the movement of the connecting rod two 10 drives the shaft bracket 13 to compress the spring damper 12. The spring damper 12 absorbs and consumes the impact force generated in the process of moving downward, avoids rigid collision between the lower die 3 and the upper die 4, protects the hot pressing plate 5 and improves the hot pressing stability. When the upper die 4 is lifted after hot pressing, the spring damper 12 releases energy, drives the shaft bracket 13 to move the connecting rod two 10, and drives the lower die 3 to rise to the initial position through the connection of the connecting rod one 9 and the connecting rod two 10. In terms of height adjustment, if the height of the lower die 3 needs to be adjusted, the magnetic ring two 15 on the threaded groove 14 at the bottom end of the vertical post 6 is rotated to move up and down along the threaded groove 14 on the vertical post 6. Since the magnetic ring one 16 at the bottom end of the movable sleeve two 8 and the magnetic ring two 15 repel each other with the same magnetic pole, the movement of the magnetic ring two 15 will drive the magnetic ring one 16, the movable sleeve two 8 and the lower die 3 connected with the magnetic ring one 16 to move up and down through the repulsive force, so as to realize fine adjustment of the height of the lower die 3 and meet the requirement of different hot pressing processes on the hot pressing gap between the upper die 4 and the lower die 3, and ensure the hot pressing effect.
