Abstract

The invention provides a limiting block sealing device and a vacuumizing tire mold. The limiting block sealing device comprises a bottom plate, a tire side plate and an upper cover, wherein the uppercover is arranged above the bottom plate in parallel; the tire side plate is fixedly between the bottom plate and the upper cover in a sealing and fitting mode; a pattern mold is correspondingly arranged on one side of the tire side plate, and the pattern mold is fixedly connected with the bottom plate and the upper cover; and an inner mold plate is mounted on the outer wall of the pattern mold ina fitting mode. The limiting block sealing device of the vacuumizing tire mold is extruded and limited through a double-layer installed sealing ring, and the sealing ring is used as a transition, sothat the sealing between steel parts is achieved, the air flow of an outer cavity of the mold and an inner cavity of the mold is effectively blocked, the good sealing effect of the bolt hole connection part of the vacuumizing mold is achieved, and the vacuum degree requirement of the inner cavity of the mold is ensured; and the structure adopts a static sealing mode, so that the sealing effect ofthe bolt hole part is achieved, and the phenomenon that the sealing ring can fail due to deformation after long-term use is avoided.

Description

technical field [0001] The invention relates to the technical field of tire production, in particular to a limiting block sealing device and a vacuumized tire mold. Background technique [0002] With the continuous update of the tire market demand, now most of the large-size AT and MT tires have patterns on the sidewall, which requires the tire mold to use a positioning structure when designing, which can realize the pattern docking, vacuumize the mould, and vulcanize. When it comes to tires, the sidewall and pattern blocks will directly determine the appearance of the tire. The sidewall is a ring, and the pattern blocks are distributed around the circumference of the sidewall. [0003] When the traditional vacuum mold solves the sealing effect of the bolt hole joint, copper sheets and other methods are routinely used, and the steel parts are in contact with the steel parts, which cannot achieve the sealing effect, resulting in poor sealing effect of the equipment. [0004]...
