Method and tooling for coating isolating agent onto surface of vulcanized capsule

Abstract

The invention discloses a method and tooling for coating an isolating agent onto the surface of a vulcanized capsule. The cooling is composed of two end circle frameworks, a lacing layer, an isolatinglayer and an isolating agent absorbing layer, the two end circle frameworks are located at the upper and lower ends of the tooling, the lacing layer, the isolating layer and the isolating agent absorbing layer are arranged between the two end circle frameworks, the two ends of each layer are connected to the two end circle frameworks and to form a ball surface by surrounding, the lacing layer, the isolating layer and the isolating agent absorbing layer are sequentially arrayed from outside to inside and tightly keep contact with one another, and the inner side of the isolating agent absorbinglayer is provided with an arc surface capable of being attached to the surface of the vulcanized capsule during expanding. By using the tooling, outside of a vulcanization work producing line, the isolating agent is coated in the tooling firstly, then the tooling is arranged on the vulcanized capsule in a sleeving mode, the surface of the vulcanized capsule and the isolating agent absorbing layerare in contact with each other fully and stick to the isolating agent by reverse sticking, and then the tooling is removed. The tooling and the coating method improve the operation efficiency, and high temperature burns can be prevented.

Description

technical field [0001] The present invention relates to the technique of coating release agent on tire vulcanization bladder, more specifically, the present invention relates to the method and tooling of coating release agent on the surface of curing bladder. Background technique [0002] The shape of the raw tire is the same as that of the tire. After the green tire is made on the molding machine, it is transported to the vulcanizing machine for vulcanization to obtain the tire. The vulcanizing bladder is one of the main components of the vulcanizing machine and participates in the vulcanization process. Before the green tire is vulcanized, it is necessary to spray a release agent inside it. The release agent is a release agent. Its function is to prevent the tire from sticking to the vulcanization bladder after vulcanization, and at the same time make the vulcanized tire have better appearance and performance. [0003] At present, there are two forms of spray release agent...

AI Technical Summary

Problems solved by technology

[0004] 1. Concentrated spraying of release agent inside the raw tire before vulcanization. The advantage of this method is that the spraying is uniform, but the disadvantage is that the production of the outer tire increases the process and prolongs the production cycle of the sulfur tire; the spraying process takes up space, increases handling, and increases environmental pollution, etc.;

[0005] 2. In the vulcanization process, the release agent is manually brushed on the vulcanization capsule. The advantage of this method is that it saves process, space and labor by relatively concentrated spraying; the disadvantage is that manual brushing is time-consuming and has a certain impact on the vulcanization capacity. Uneven brushing has a certain impact on the quality of the tire, and there is no guarantee for the safety of the brushing personnel in a high temperature environment
