Description

Vulcanizing device for curing rubber tire with uniform heat transfer

Technical Field

The utility model relates to a technical field of rubber tire processing, concretely relates to vulcanizer that rubber tire solidification of even heat transfer was used.

Background

Pneumatic rubber tires are generally produced by vulcanizing a raw tire in a laminator for a certain period of time by inflating the tire while maintaining a certain pressure, the green tire having a flow-extending property at a certain temperature. The raw tire is tightly attached to the inner surface in the mold, and then the rubber tire finished product with higher strength and toughness can be obtained through shaping treatment.

There are also problems in the prior art in that heating is generally required in the vulcanization plant, and superheated gases such as nitrogen or steam are generally used. However, the use of nitrogen is costly and is generally replaced by steam. However, after the heat exchange, the water vapor is condensed to generate liquid water, which is retained at the bottom.

The temperature of the remaining liquid water is not uniform at other portions and is lower than that at other portions, and therefore, uneven vulcanization of the tire may occur, and the performance of the tire may be unstable. Condensation of water vapor also results in long sulfiding processes, resulting in productivity cracking.

Accordingly, there is a need for improvements in the prior art to achieve a uniformly heat-transferring curing apparatus for curing rubber tires.
