Embodiment

[0031] The invention provides a method for curing rubber tires, which includes the step of vulcanizing with a vulcanizing device, and vulcanizing and molding the green tire base through the vulcanizing step.

[0032] The structure of the specific vulcanization device 1 is as follows: figure 1 As shown, the vulcanization device 1 is rotationally symmetrical about the axis A-A'. It includes an upper mold 21 located above, a lower mold 22 located below, and an outer mold 23 located on the outside. The outer mold 23 has a frustum-shaped outer surface 231; the inner side of the outer mold 23 is also stacked with The inner mold 24, the upper mold 21, the lower mold 22 and the inner mold 24 form a closed inner cavity 3; the vulcanization device also includes a snap ring 4, which can move in the axial direction and is used for engaging The outer surface 231 of the outer mold 23; the snap ring 4 includes an annular inner pedestal 42 and an outer snap ring 43 with a concave cavity insi...

Abstract

The invention relates to a rubber tyre curing method. The rubber tyre curing method comprises the step of vulcanizing by using a vulcanizing device, wherein vulcanization molding is carried out on a green tyre in the step of vulcanizing. Vulcanization molding comprises the following steps of S1, introducing heating water vapor into an inner cavity to heat the inner side of the green tyre; and S2,introducing heating water vapor into an outer cavity for auxiliary heating. According to the rubber tyre curing method, the temperature difference caused by condensed water is reduced through auxiliary heating, so that problems like insufficient vulcanization or long vulcanization time can be solved. A heat conduction element is arranged in a cavity for auxiliary heating, so that the temperature difference during external heating is further reduced, the post-forming quality of a tyre is improved, and the phenomenon of uneven vulcanization is avoided.

Description

technical field [0001] The invention relates to the technical field of rubber tire processing, in particular to a rubber tire curing method. Background technique [0002] Pneumatic rubber tires are generally prepared in a laminator, using raw tires that have the ability to flow at a certain temperature, and are vulcanized within a certain period of time by inflating and maintaining a certain pressure. The raw tire is tightly attached to the inner surface inside the mold, and then after shaping treatment, the finished rubber tire with high strength and toughness can be obtained. [0003] There are still certain problems in the prior art. Generally, heating is required in vulcanization equipment, and superheated gas, such as nitrogen or water vapor, is usually used. However, the cost of using nitrogen is high, and water vapor is generally used instead. However, after the heat exchange, the water vapor will condense to produce liquid water, which stays at the bottom. [0004...
