[0030] Please refer to Figure 1 , Figure 2 In this embodiment, the cylinder 21 and the top plate 11 are detachably arranged, and the upper and lower installation positions of the cylinder 21 on the top plate 11 can be adjusted according to the specifications of the upper mold 3, so as to adjust the displacement distance of the top plate 11 when the hydraulic rod 13 is pushed quickly, so that the overall device can be suitable for molds of multiple specifications.

[0031] In a preferred embodiment, a ventilation pipe 16 is fixedly provided at the center of the top surface of the top plate 11 for connecting to an air pump device; one end of the ventilation pipe 16 is fixedly connected to the mounting groove 14 .

[0035] In a preferred embodiment, a displacement sensor 5 is installed at one end of the top plate 11 along the diameter direction.

[0036] Please refer to Figure 1 , Figure 2 In this embodiment, after replacing the tire mold, because the specifications of the mold are different, it is necessary to re-measure and adjust the rapid mold moving distance of the hydraulic rod 13. During measurement and adjustment: the upper mold 3 and the lower mold 4 are installed on the top plate 11 and the bottom plate 12 respectively, and the hydraulic rod 13 is slowly started.

[0037] How this application works:

[0038] Installing the mold: first, place the upper mold 3 into the installation groove 14 along the axial direction of the top plate 11, so that the top surface of the upper mold 3 is close to the inner wall of the top surface of the installation groove 14. At this time, the sealing ring 17 ensures that a sealed space is formed between the top surface of the upper mold 3 and the inner wall of the top surface of the installation groove 14, and this space is connected to the air pump equipment by the ventilation pipe 16. Then the air pump provides high-pressure suction to make the upper mold 3 tightly adsorbed inside the installation groove 14, and then the lower mold 4 is placed and installed in the placement groove 15.

[0039] Mold closing work: start the hydraulic rod 13, the hydraulic rod 13 quickly pushes the top plate 11 downward, during the downward movement, the cylinder 21 passes through the through hole 25, and the rubber ring 26 at the bottom end of the damping spring 22 presses against the bottom end of the spring groove 23. As the damping spring 22 further contracts, the thrust of the hydraulic rod 13 is blocked and increased, and the downward movement of the top plate 11 slows down until it stops, and the mold closing is completed. Then, the nut 24 is screwed on the bottom end of the cylinder 21.
