Abstract
The invention particularly relates to a tooth-shaped rubber sleeve die vulcanizing device and a production technology, and belongs to the technical field of rubber sleeve die vulcanizing. The tooth-shaped rubber sleeve die vulcanizing device comprises a vulcanizing tank, a tooth-shaped steel die, a rubber sheet and a flat rubber sleeve. The rubber sheet wraps the tooth-shaped steel die, the flat rubber sleeve sleeves the outer side, and the end portion of the flat rubber sleeve is sleeved with a sealing cover. The sealing cover is provided with an air pipe I extending to the outer portion of the vulcanizing tank. A vacuum cavity is formed in the middle of the tooth-shaped steel die, an air pipe II is arranged at a port of the vacuum cavity, the air pipe II penetrates the sealing cover andextends to the outer portion of the vulcanizing tank, a plurality of air holes are formed in the inner wall of the vacuum cavity, and the air holes penetrate the tooth-shaped steel die and extend to tooth grooves between outer wall tooth profiles. The vulcanizing tank is provided with an air pipe III. Tooth filling of the tooth-shaped rubber sleeve die of the tooth-shaped rubber sleeve die vulcanizing device is very full, the phenomenon of tooth shortage is avoided, the service life is longer than the service life of a die pressing rubber sleeve by 1 / 3, the production technology is simple, efficiency is improved, and cost is low.
Description
technical field [0001] The invention belongs to the technical field of vulcanization of rubber sleeve molds, and relates to a vulcanization process of tooth-shaped rubber sleeve molds, in particular to a vulcanization device and production process of tooth-shaped rubber sleeve molds. Background technique [0002] Tooth-shaped rubber sleeve mold is an external mold for vulcanization of rubber trimmed V-belts. It is an indispensable rubber mold in the production of reverse molding vulcanization process. It can be used repeatedly for 200 to 400 times. Generally, according to different Products will be designed with different tooth-shaped rubber sleeves. [0003] The general conventional production method is molding, but sometimes the joint of the molded rubber sleeve is not very firm, and it is easy to disengage during the production process, which affects the service life of the rubber sleeve and easily causes the scrap of the produced product. In addition, smaller rubber sle...
