Description

Vulcanizing machine and tire curing method

technical field

The invention relates to the technical field of rubber product manufacturing, in particular to a vulcanizing machine and a tire vulcanization method.

Background technique

Vulcanizing machine is a kind of equipment that tire manufacturing enterprises invest a lot in. At the same time, vulcanization is also an important process to control tire quality. Therefore, it has high requirements for equipment cost control, process quality and technical performance.

Existing vulcanizers will generate soot, exhaust gas and steam when vulcanizing green tires. These fumes and exhaust gases leak to the outside of the curing chamber, causing the curing workshop to be full of peculiar smell, and the steam will increase the temperature in the workshop after running out. It makes the working environment of the vulcanization workshop worse.

In addition, the existing tire vulcanization mold adopts a movable mold, and the movable mold is divided into upper and lower parts. When in use, the tire blank to be vulcanized is put into the lower part of the movable mold, and then the upper part of the movable mold is connected with the lower part. to seal the embryo in the movable mold. After the flexible mold is sealed, the tire in the mold is heated to a high temperature to soften it. At the same time, the bladder inside the tire is inflated to press the tire to the mold, so that patterns are formed on the tire, and the air in the flexible mold will prevent the rubber from completely filling the flexible mold. The resulting tires have many air bubbles.

In order to solve the above problems, the traditional vulcanizing machine is provided with a vent hole on the movable mold, so that when the rubber is filled into the movable mold, the gas in the movable mold can be discharged.
