Title:
TIRE VULCANIZATION DEVICE AND METHOD FOR ASSEMBLING TIRE VULCANIZATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/029725
Kind Code:
A1
Abstract:
In order to accurately position a sector relative to the side plates in a tire vulcanization device, this tire vulcanization device is equipped with: sectors for molding the tread section of the tire, a segment which moves the sectors in the radial direction of the tire and to which the sectors are affixed, a bolt for affixing the sectors to the segment, a ring-shaped jacket ring provided outside the segment in the radial direction of the tire, a pair of upper and lower side plates for molding the sidewall section of the tire, and mold-splitting surfaces formed between the sectors and each of the pair of upper and lower side plates. The mold-splitting surfaces extend outward in the radial direction of the tire from mold inside end sections, and are positioned in a manner such that the mold inside end sections are located on the tread section. The segment is provided so as to be capable of adjusting the sector-affixing location in the vertical direction. The jacket ring is provided with a through-hole that passes therethrough in the tire radial direction, and when the jacket ring moves downward relative to the segment so as to cover the outside of the segment in the tire radial direction, sectors which are adjacent to one another in the tire circumferential direction are tightly adhered to one another, and the through-hole and a bolt hole provided in the segment connect with one another.
