Two pairs of three-plate inner tube vulcanizing moulds

Abstract

The invention relates to two pairs of three-plate inner tube vulcanizing moulds. Each mould comprises an upper mould, a lower mould and a middle mould, wherein the upper mould consists of an upper bottom plate and an upper mould body; a first annular air path is arranged on the upper part of the upper mould body; the upper bottom plate is welded above the upper mould body to seal the first annular air path; the lower mould consists of a lower bottom plate and a lower mould body; a second annular air path is arranged at the bottom of the lower mould body; the lower bottom plate is welded at the bottom of the lower mould body to seal the second annular air path; the middle mould consists of two half middle mould bodies; two third annular air paths are arranged on the opposite sides of the two half middle mould bodies, respectively; the two half middle mould bodies are welded oppositely to seal the two third annular air paths; a first half middle cavity and a second half middle cavity are formed in the upper part and the bottom part of the middle mould, respectively; the first half middle cavity and an upper half cavity oppositely form a first cavity, and the second half middle cavity oppositely forms a second cavity. According to the two pairs of three-plate inner tube vulcanizing moulds, the aim of energy saving is fulfilled, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to an inner tube vulcanization mold. Background technique [0002] At present, most vulcanization molds on the market are in the form of two pieces of upper and lower molds, such as the Chinese utility model patent (application number: 95213998.7 application date: 1995-06-01). This kind of mold form has low steam utilization during the vulcanization process. According to the conduction of heat energy, it is conducted to the surroundings. Only part of the heat energy is conducted to the product, and most of the heat energy is dissipated into the air, which leads to a lot of energy waste. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a three-piece two-pair inner tube vulcanization mold, which can make better use of energy, reduce energy waste, and reduce power costs. [0004] In order to achieve the above object, the present inventio...
