Problems solved by technology

Since the mechanism including the driving source and the piping for supplying the cooling medium needs to be installed near the cooling device, the cooling device is likely to be enlarged and the cost of such peripheral equipment and such equipment and installation will be reduced. Institutions become more complex

Embodiment Construction

[0086] figure 1 and figure 2 A conventional post-cure inflator (PCI) and cured tire cooling method with reference to the present invention is shown. After vulcanization, the inflator 101 is installed on the back surface of the vulcanizer 102 ( figure 1 and figure 2 at the specified distance on the right side of ). The post-vulcanization inflator 101 includes an expansion cooling unit 103 for expanding and cooling the tire 1 . The number of expansion cooling units 103 is set equal to the number of molds of the vulcanizer 102 . Specifically, the inflator 101 after vulcanization includes: two expansion cooling units 103 arranged in parallel, and the lower rim lifting mechanism 125 for lifting the lower rim mechanism 2 of the two expansion cooling units 103 at the same time; After receiving two vulcanized tires 1 from the vulcanizer 102 at the same time, they are expanded and cooled simultaneously.

[0087] The vulcanizer 102 may be installed parallel to the post-vulcaniza...

Abstract

The invention concerns an apparatus and a method for shock cooling of a cured pneumatic tire. The apparatus for shock cooling a vulcanized tire includes a vulcanized-tire holding mechanism for holding a vulcanized tire and a tank for holding fluid to shock cool the vulcanized tire. The vulcanized tire is submerged in the fluid for between 4 and 60 minutes whereby the vulcanized tire reaches a predetermined temperature.

Description

technical field [0001] The present invention relates to a device and method for cooling vulcanized pneumatic tires. Background technique [0002] Conventionally, organic fibers of polyester, nylon, or similar materials are used as carcass members that are internal reinforcing fibers of pneumatic tires. During the cooling of the tire after vulcanization is complete, these reinforcing fibers shrink. However, due to the inconsistency, arrangement, and molding state of each component, the degree of shrinkage of each component is not uniform. In natural cooling only by exposing the pneumatic tire to the air, the pneumatic tire may be deformed due to a difference in the degree of shrinkage, thereby making the pneumatic tire a defective product or degrading the uniformity performance of the pneumatic tire. [0003] Therefore, it is common to inflate air into the interior of the pneumatic tire with a post-vulcanization inflator after vulcanization is completed, and to cool the pne...
