Embodiment Construction

[0011] An injection type vulcanization bladder mold for a radial tire, comprising an upper mold 1, a lower mold 2, and a core mold 3, in the core mold cover 6 (or in the upper mold) above the mold cavity 4 formed by the upper mold, the lower mold and the core mold , the injection hole 5 communicating with the inner cavity of the mold is set, and the vacuum passage 7 communicating with the inner cavity of the mold is set under the inner cavity of the mold.

[0012] A gas channel 8 is arranged in the middle of the mandrel, and the gas channel communicates with the outer surface of the mandrel through an air valve 9, and can be demolded by gas. The inner cavity of the core mold communicates with the inlet and outlet pipes 10 and 11 of the heating medium. The outer cavities of the upper and lower molds are provided with flow-guiding partitions 12 for the heat-conducting medium. There are multiple diversion partitions arranged radially. Mold surface accuracy ≤0.05mm, concentricit...

Abstract

The invention discloses a radial-ply tire injection-type curing bladder mould, which comprises an upper die, a lower die and a mandrel. The invention is characterized in that injection orifices communicated with an inner die cavity formed by the upper die, the lower die and the mandrel are arranged above the inner die cavity; a vacuumized passage communicated with the inner die cavity of the mould is arranged below the inner die cavity of the mould. Exhaust lines inside the inner die cavity of the mould are integrated with the mould. A plurality of guide partitions of heat conduction media are arranged inside the outer cavities of the upper die and the lower die, and are arranged in a radial shape. The invention has rational structure and works at high efficiency; rubber is injected conveniently and quickly.

Description

Technical field: [0001] The invention relates to a mold. Background technique: [0002] The existing tire vulcanization bladder mold has complex glue injection, difficult demoulding, low yield of finished products and unsatisfactory working performance. Invention content: [0003] The purpose of the present invention is to provide a radial tire injection curing bladder mold with reasonable structure and good working effect. [0004] Technical solution of the present invention is: [0005] An injection-type vulcanization bladder mold for a radial tire, comprising an upper mold, a lower mold, and a core mold, characterized in that an injection hole communicating with the inner cavity of the mold is set above the inner mold cavity formed by the upper mold, the lower mold and the core mold , under the inner cavity of the mold, a vacuuming channel communicating with the inner cavity of the mold is set, the exhaust rib line in the inner cavity of the mold is integrated with th...
