Description

Technical Field

[0001] This utility model relates to the field of vulcanized tire cooling technology, and in particular to a vulcanized tire cooling device. Background Technology

[0002] Tire vulcanization cooling is a crucial process after tire vulcanization. Tires are tire blanks composed of rubber compounds and reinforcing materials. In a vulcanization mold, under high temperature and high pressure vulcanization media (hot water, steam, inert gas, etc.), the rubber macromolecules undergo a vulcanization cross-linking reaction, forming a usable rubber composite material. After the tire blank has completed proper vulcanization in the mold, the physical and mechanical properties of the rubber reach their optimal state. Continuing vulcanization will lead to over-vulcanization, resulting in performance degradation. Therefore, timely cooling is necessary to prevent or reduce over-vulcanization. Thus, tires require cooling treatment after vulcanization.

[0003] In the prior art, Chinese patent CN220903888U discloses a vulcanized tire cooling device, belonging to the field of tire production equipment. A linear guide rail is installed on one side of the vulcanizing machine, and a cooling mechanism is fixed at the far end of the linear guide rail. An upper cooling mold is fitted onto the upper central mechanism at the upper end of the cooling mechanism. The upper cooling mold is controlled by a lifting cylinder to slide up and down along the upper central mechanism. The upper cooling mold includes an upper cooling mold body, an upper cooling mold cavity, and an upper steel ring. The upper cooling mold body is pressed against the outer edge of the upper steel ring. The cooling mold has an internally machined upper mold cavity. A slide is installed on the linear guide rail of the lower fixed platform of the cooling mechanism between the cooling mechanism and the vulcanizing machine. A lower central mechanism is vertically fixed on the slide, and a lower cooling mold is fitted on the lower central mechanism. The lower cooling mold includes a lower cooling mold body, a lower cooling mold cavity, and a lower steel ring. The lower cooling mold body is pressed against the outer edge of the lower steel ring. The lower cooling mold cavity is machined inside the lower cooling mold body. The upper and lower cooling mold cavities are connected to the cooling medium pipeline. However, the following defects still exist:

[0004] (1) The existing cooling device introduces cooling water into the mold cavity to cool the vulcanized tire. However, when the water flows in the cavity, the water flow speed may be slow due to the large space, resulting in low heat exchange efficiency and poor cooling effect.

[0005] (2) In the prior art, the temperature at the water inlet of the cooling device is often low when cooling vulcanized tires, resulting in poor cooling uniformity.

[0006] Therefore, we have made improvements to this and proposed a vulcanized tire cooling device. Utility Model Content

Example 1

[0027] See Figures 1-6 , Figure 1A schematic diagram of a vulcanized tire cooling device is shown. As shown, the vulcanized tire cooling device of this invention includes a base plate 1. A bracket 2 is fixedly connected to the upper end of the base plate 1. A first telescopic cylinder 3 is fixedly connected to the upper end of the bracket 2.

A first rotating shaft 11 is rotatably connected to the center of the upper cooling plate 5. The shaft end of the first rotating shaft 11 passes through the upper cooling plate 5 and is fixedly connected to an upper cooling mold 12. A rotating mechanism 13 for driving the first rotating shaft 11 to rotate is provided on the upper cooling plate 5. The lower cooling plate 6 is located at its center... A second rotating shaft 14 is rotatably connected, with its shaft end passing through the lower cooling plate 6 and fixedly connected to the lower cooling mold 15. Two symmetrical and fixedly connected lugs 16 are attached to the upper cooling mold 12, and two symmetrical and fixedly connected clamping heads 17 corresponding to the lugs 16 are attached to the lower cooling mold 15. The first telescopic cylinder 3 drives the connecting frame 4 to move up and down, thereby closing and separating the upper cooling mold 12 and the lower cooling mold 15. The cooling pipe 8 is connected to the cooling water circulation system through the inlet head 9 and the outlet head 10. The cooling water flows in the cooling pipe 8, carrying away the heat of the tire and achieving a cooling effect. The water flow speed is relatively fast, and the heat exchange efficiency is higher. The upper cooling mold 12 and the lower cooling mold 15 are convenient for bearing the vulcanized tire and for cooling it.

The second motor 1303 drives the worm 1304 to rotate. The rotation of the worm 1304 can drive the worm gear 1301 and the first rotating shaft 11 to rotate. The rotation of the first rotating shaft 11 causes the clasp 16 to drive the clasp head 17 to rotate, thereby enabling the lower cooling mold 15 to rotate, thus facilitating uniform cooling of the tire.

[0030] The upper end face of the lower cooling mold 15 is fixedly connected with a retaining ring 18, and the lower end face of the upper cooling mold 12 is provided with a retaining groove 19 that matches the retaining ring 18; the retaining ring 18 and the retaining groove 19 enable the upper cooling mold 12 and the lower cooling mold 15 to be easily aligned and fixed together, ensuring sealing.

A second telescopic cylinder 22 is fixedly connected to the lower end face of the lower cooling plate 6. The driving end of the second telescopic cylinder 22 passes through the lower cooling plate 6 and is fixedly connected to the lower end face of the plug 21. The positioning sleeve 20, the plug 21 and the second telescopic cylinder 22 can ensure the positioning of the lower cooling mold 15 when it is not in use, and also facilitate the docking of the upper cooling mold 12 and the lower cooling mold 15.

[0032] A set of heat dissipation fins 23 are uniformly fixedly connected to the outer peripheral sidewalls of the upper cooling mold 12 and the lower cooling mold 15; the design of the heat dissipation fins 23 increases the heat dissipation area, improves the cooling efficiency, and ensures the rapid cooling of the tire.

[0033] Working principle:

[0034] This utility model provides a vulcanized tire cooling device. During operation: First, the first motor 703 drives the threaded rod 702 to rotate, causing the shifting block 704 to move. The movement of the shifting block 704 drives the base frame 705 and the lower cooling mold 15 to move, moving the lower cooling mold 15 to the vulcanized tire receiving position. After the vulcanized tire is demolded, it falls into the lower cooling mold 15 after being moved out. Then, the lower cooling mold 15 is reset. The first telescopic cylinder 3 is activated to lower the upper cooling mold 12 and the retainer 16 to mate with the lower cooling mold 15 and the retainer 17. Then, the second telescopic cylinder 22 drives the plug... 21 descends to disengage it from the positioning sleeve 20, and cooling water is introduced into the cooling pipe 8 to cool the upper cooling mold 12 and the lower cooling mold 15, thereby cooling the vulcanized tire. At the same time, the second motor 1303 drives the worm gear 1304 to rotate. The rotation of the worm gear 1304 drives the worm wheel 1301 and the first rotating shaft 11 to rotate. The rotation of the first rotating shaft 11 causes the clasp 16 to drive the clasp head 17 to rotate, thereby enabling the lower cooling mold 15 to rotate, and thus the tire inside to rotate, which can uniformly cool the vulcanized tire and improve the cooling effect.

All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
