Tire segment mold

Abstract

The invention discloses a tire segment mold, and belongs to the field of tire molds. The tire segment mold can be widely applied to riding-use tires, light truck tires, engineering tires and giant tires, and comprises a mold body and an inner side tire forming capsule. A sealed heating chamber is arranged on the mold body. An electric heating device and a heating medium are arranged in the sealedheating chamber. The electric heating device is electric heating coils. Water or other liquids with high specific heat capacity, or anti-corrosion liquids or solids which are heated to 100-200 DEG C and can generate phase change serve as the heating medium preferably. In addition, the electric heating device is preferably arranged in the position, away from the inner side tire forming capsule, ofthe cavity wall of the sealed heating chamber, and the electric heating device is prevented from directly heating the mold.

Description

technical field [0001] The invention relates to the field of tire molds, in particular to a tire flexible mold. Background technique [0002] The tire active mold is the necessary equipment for tire vulcanization molding. At present, the tire vulcanization process is summarized as follows: the green tire is placed in a mold, and the mold is heated by water vapor. However, the existing water vapor requires additional pipelines to enter the mold. The installation of pipelines and the acquisition and transportation of water vapor will increase the cost. The mold is also easily corroded by steam during long-term use, and its service life is limited. influences. Moreover, it is difficult to precisely control the vulcanization temperature by water vapor. Therefore, there is now a way of heating the mold with a heating coil, but the current heating method is mostly to wrap the heating layer on the outer layer of the mold. Although this method is simple to process and operate, th...

Problems solved by technology

However, the existing water vapor requires additional pipelines to enter the mold. The installation of pipelines and the acquisition and transportation of water vapor will increase the cost. The mold is also easily corroded by steam during long-term use, and its service life is limited. influences

Moreover, it is difficult to precisely control the vulcanization temperature through water vapor

Therefore, there is now a way of heating the mold with a heating coil, but the current heating method is mostly to wrap the heating layer on the outer layer of the mold. Although this method is simple to process and operate, the heating heat is easy to waste, and the vulcanization parameters are difficult to control.
