Abstract

The invention relates to a tire vulcanization inner mould, and belongs to the field of tire production equipment. The tire vulcanization inner mould is characterized in that a piston rod and a base are fixedly connected, a wedge-shaped surface of the base is alternately provided with a narrow tile side guide rail and a wide tile side guide rail, and the narrow tile side guide rail is matched with a narrow tile side sliding block fixed on a narrow drum tile support; the wide tile side guide rail is matched with a wide tile side sliding block fixed on a narrow drum tile support, a limiting disc is sheathed on the piston rod, the circumference of the upper side surface of the limiting disc is alternately provided with a narrow tile bottom sliding block and a wide tile bottom sliding block, and the narrow tile bottom sliding block and the wide tile bottom sliding block are respectively matched with a narrow tile bottom guide rail and a wide tile bottom guide rail fixed on the narrow drum tile support and the wide drum tile support. The tire vulcanization inner mould provided by the invention has the advantages that a mechanical mechanism is adopted to realize the radial dilatation of the mould, the structure precision is high, problems of the existing vulcanization technology that the expansion of a capsule is not thorough and the structure is asymmetric are fundamentally solved, the vulcanization pressure is greatly improved, vulcanized manufacture of the tire can be preformed for a long time, and the problems in the original technology that the service life of the capsule is long and the capsule needs to be frequently changed is solved.

Description

technical field [0001] The invention relates to the field of tire production equipment, in particular to a tire vulcanization inner mold. Background technique [0002] As we all know, the current process of tire vulcanization is to apply high-intensity vulcanization pressure to the green tire with the cooperation of the bladder and the outer mold, and at the same time transfer heat to the green tire by virtue of the high-temperature steam (or superheated water) inside the bladder and the mold. Under the action of such high heat pressure, a chemical cross-linking reaction occurs between the rubber material inside the green tire and the vulcanizing agent, and finally endows the finished tire with good mechanical properties and pattern appearance. The tire shaping vulcanizer is the special equipment for tire vulcanization that is widely used based on this process. [0003] There are certain defects in the existing bladder vulcanization process. On the one hand, problems such ...
