Description

Technical Field

[0001] This utility model belongs to the field of tire vulcanization technology, specifically, it relates to a tire vulcanization mold and vulcanization equipment. Background Technology

[0002] In the existing technology, the heating methods used for tire vulcanization molds include steam heating and electric heating. As a type of electric heating, the heating film has problems such as low heat transfer efficiency and uneven workpiece temperature during application. Tire vulcanization has high requirements for the temperature uniformity after mold heating, which directly affects the tire vulcanization efficiency and vulcanization quality.

[0003] Tire vulcanizing molds are mainly used for the vulcanization and molding of tires. Currently, the heating points are mainly the upper heating plate, lower heating plate, and middle mold sleeve of the vulcanizing equipment, providing the necessary external heat for tire vulcanization. However, in the actual vulcanization process, many factors affect heat transfer, and there will be temperature differences at different locations of the mold that ultimately bond with the tire blank. This leads to differences in vulcanization efficiency and degree at different locations of the tire, affecting the quality of tire vulcanization. Utility Model Content
