Embodiment Construction

[0032] In order to overcome the above-mentioned problems in the prior art, the present invention provides a sealing packing for the steam chamber of a tire vulcanizing machine and a production method thereof. Next, the sealing packing and its production method will be described in detail.

[0033] figure 2 Show the sectional structure diagram of the sealing packing root of the present invention, as figure 2 As shown, the sealing packing includes a main body core type 1 made of compounded rubber.

[0034] It also includes a fiber ply reinforcement layer 3 arranged on the main body core type 1, and the fiber reinforcement layer is applied on the outer surface 2 of the main body core type which is in contact with the lower half mold of the steam chamber.

[0035] The sealing packing mentioned above is in the shape of a ring. In comparison, the ring shape has no cutout and end plug contact, so the seal is good.

[0036] The height at which the fiber reinforced layer 3 is app...

Abstract

The invention discloses a sealing packing for a steam chamber of a tire vulcanizer and a method for producing the same. The sealing packing comprises a main body core pattern made of mixing rubber, and further comprises a fiber cord fabric reinforced layer arranged on the main body core pattern, wherein the fiber reinforced layer is coated on an outer surface where the main body core pattern is contacted with a lower half mold of the steam chamber. By coating the fiber reinforced layer outside the main body core pattern made of mixing rubber, the fiber of the reinforced layer can effectively prevent aging cracks of the rubber and can increase the using times of the packing while enhancing the entire intensity of the packing. Therefore, the sealing packing and the method improve the sealing effect of the steam chamber during a vulcanizing process of the tire vulcanizer, stabilize the tire vulcanization process, enhance the quality of a tire product and lower the production cost of the tire.

Description

technical field [0001] The invention relates to a sealing packing, in particular to a sealing packing used in the steam chamber of a tire vulcanizing machine in the field of rubber machinery and a production method thereof. Background technique [0002] It is currently used for the sealing packing of the steam chamber of the tire vulcanizing machine. In order to adapt to the high temperature and high pressure conditions, the material is mostly made of silicone rubber, which is expensive. [0003] figure 1 A cross-sectional structure diagram showing a sealing packing in the prior art, such as figure 1 As shown, it is made of a single silicone rubber material, which is cast, extruded or cut from the corresponding mold. [0004] At the same time, professional sealing packing manufacturers mostly use continuous production in production. Therefore, it can only be cut according to the length of the packing chamber installed in the vulcanizer steam chamber during use. [0005] ...
