Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of tire flexible molds, in particular to a tire flexible mold without air holes that reduces the generation of tread rubber hair. Background Art
[0002] The tire production process involves vulcanization and molding of the tire. During the vulcanization process, the gas in the mold needs to be discharged, which will cause rubber hair to form on the tire tread at the exhaust hole. Their presence does not affect the normal use of the tire, but before the tire leaves the factory, most manufacturers will carry out a process to remove these "fetal hairs" to ensure the neat appearance of the tire and avoid foreign matter caused by the shedding of "fetal hairs" during use from entering between the tire and the wheel hub, causing unnecessary trouble. The special process for removing the rubber hair on the tire tread will mean adding corresponding workstations and production equipment, adding relevant personnel, which will lead to an increase in corresponding production costs. In addition, there is a probability of tire damage during the removal of the rubber hair on the tire tread, which increases the overall probability of defective tires, which has a negative effect on the production and operation of the company.
