Air hole processing device for tire mold

Abstract

The invention relates to the field of mold manufacturing, in particular to an air hole processing device for a tire mold, comprising a support frame for supporting the tire mold and a tool holder for clamping a drill bit. The support frame is provided with a clamping unit for fixing the tire mold. The support frame is fixed on the first rotation unit, and the first rotation unit is fixed on the second rotation unit. The rotation axes of the first rotation unit and the second rotation unit are arranged horizontally and the two rotation axes are perpendicular to each other. The first rotation The unit drives the support mechanism to rotate around the rotation axis of the first rotation unit, and the second rotation unit drives the first rotation unit to rotate around the rotation axis of the second rotation unit. The cooperation of the first and second rotation units enables the support frame to rotate in multiple directions. Rotate to ensure that the tire mold is adjusted to a suitable processing position, ensure that the drill bit is perpendicular to the tread to be processed, improve the angle accuracy of the tread air hole, save the working time of implanting the air hole sleeve, and facilitate the replacement of the spring air hole sleeve in the later mold.

Description

technical field [0001] The invention relates to the field of tire mold manufacturing, in particular to a tire mold air hole processing device. Background technique [0002] During the tire vulcanization process, in order to release the air in the mold cavity so that the rubber can be evenly distributed in the mold, it is necessary to open a plurality of air holes on the tread surface of the tire mold. The air hole is thin and long, and the center line of the air hole needs to be perpendicular to the tangent line of the tread where it is located. The tool is very easy to deviate during processing, which makes it difficult to insert the air hole sleeve, and the processing is very difficult. At present, there is no device specially used for processing air holes, and the holes are directly drilled manually, and the randomness of personnel is too great. First of all, it is difficult to ensure whether the drill bit is perpendicular to the tread at the beginning, and secondly, it ...

AI Technical Summary

Problems solved by technology

First of all, it is difficult to ensure whether the drill bit is perpendicular to the tread at the beginning, and secondly, it is even more difficult to ensure whether the drill bit is deflected during processing, resulting in the punched air holes and the tread are not perpendicular, and the air hole sleeves will be high and low after being implanted into the mold. Low, the quality of the mold is poor, affecting the quality of the final product
