Description

Technical Field

[0001] The utility model relates to the technical field of rubber and plastic machinery, and more specifically to an anti-internal leakage combined sealing device for a central mechanism of a vulcanizing machine. Background Art

[0002] Product sealing refers to the use of appropriate materials and technology to completely seal the product packaging in order to protect the product from external contamination, extend the shelf life of the product and maintain the freshness of the product. Sealing is crucial for products in all walks of life. It not only protects the quality of the product, but also enhances the product's image and market competitiveness. In tire industry manufacturing companies, the vulcanization production process requires a combined sealing device to prevent internal leakage of the vulcanizer center mechanism.

[0003] During the vulcanization production process, the central mechanism is mainly responsible for functions such as vulcanization medium transportation and capsule shaping. However, due to poor sealing effect, internal leakage and other phenomena occur, resulting in large energy consumption losses. At the same time, due to the use of high-temperature vulcanization processes such as nitrogen, capsule oxides will stick to the central shaft, causing abnormal lifting of the central shaft, thereby affecting the shaping accuracy and the quality of the tire. At the same time, the capsule oxides stuck to the central shaft are difficult to clean and need to be polished to remove. After multiple polishing, the accuracy of the central shaft will be damaged, thus affecting its service life. Utility Model Content

Example

[0029] When the capsule 100 is delaminated, it will enter the return pipe and block the pipe, resulting in low internal temperature, which will seriously affect the temperature, one of the three elements of vulcanization, and make the tire quality abnormal. Although delayed vulcanization is used to ensure the quality of the tire when the internal temperature is low, the energy consumption is indirectly increased, which cannot meet the low-carbon requirements. At the same time, it is difficult to clean the debris in the pipe, which seriously affects the efficiency of maintenance. The following solution is used to solve the problem.

The return water port groove 12 adopts a honeycomb structure, which effectively reduces the blockage caused by the delamination capsule 100 entering the return pipe. At the same time, the honeycomb structure and the return water port groove 12 generate corresponding turbulence or vortex, so that the debris does not block the return water port groove 12, and the cleaning of the debris in the internal pipe of the return water port groove 12 is reduced, which improves the maintenance efficiency. The good sealing performance makes the tire have good pressure holding ability in the vulcanization stage and the nitrogen process / superheated water stage, and the product quality is guaranteed.

The lower module is fixedly connected to the surface of the vulcanizer base 104, and the upper module is fixedly connected to the injection cover 4 by screws and bolt connection countersunk holes 5.

[0032] The utility model uses the following steps: When the anti-internal leakage combined sealing device for the central mechanism of the vulcanizer is used, when shaping, the vulcanizing medium 101 enters from the water inlet groove 11 and fills the capsule 100. After shaping, the vulcanizing medium 101 in the capsule 100 flows out from the water return groove 12 to achieve a circulation effect. The water inlet groove 11 and the water return groove 12 are both one-divided-two combinations, and are arc-shaped, with inlets and outlets with angles. Through the optimization of the layout, the flow rate is uniform. When vacuuming, the water return groove 12 uses two water outlets distributed in an arc shape, which can quickly reduce the internal pressure to the process conditions and reduce the vacuuming.

The water return groove 12 adopts a honeycomb structure, which effectively reduces the blockage caused by the delamination capsule 100 entering the return pipe. At the same time, the honeycomb structure and the water return groove 12 produce corresponding turbulence or vortex, so that the debris does not block the water return groove 12, and the cleaning of the debris in the internal pipe of the water return groove 12 is reduced, which improves the maintenance efficiency. The good sealing performance makes the tire have good pressure holding ability in the vulcanization stage and the nitrogen process / superheated water stage, and the product quality is guaranteed. The good sealing performance can reduce the delayed vulcanization caused by leakage and meet the requirements of low carbon and environmental protection.
