Background technique

The production process of tires mainly includes four steps, banburying, components, molding, and vulcanization. The vulcanization process mainly refers to the vulcanization of the outer tire. At present, the vulcanization of tires is carried out by means of model pressure. In this process, a vulcanizing machine is used to set the outer diameter of the outer tire forming the tire blank to be smaller than the inner diameter of the model. During vulcanization, the tire blank is filled with water tires or bladders, and high-pressure hot water is added to the water tires to utilize the expansion of the water tires or bladders. The pressure fills the tire blank into the model, and the tire vulcanization adopts the method of gradual temperature rise, low temperature and long time vulcanization, so as to make the rubber material fully flow and heat transfer to ensure the vulcanization quality.

There are two main types of tire vulcanization equipment: one is a universally used setting vulcanizer, which adopts an upper-opening type and realizes the molding of one tire at a time. The second is the vertical vulcanizing machine, which adopts a side-opening type and can install several tire molds of different specifications in the vertical direction.
