Bottom-opening movable mold bow seat positioning device

Abstract

The invention provides a downward-opening type positioning device for a segmented mold arch seat. The positioning device comprises arch seats, wherein the arch seats are arranged at the lower part of an upper cover plate; inner positioning blocks and outer positioning blocks are arranged on the circumference of the upper cover plate and are arranged in a staggered manner; a groove matched with the inner positioning block is arranged at the middle part of the upper end of each arch seat; and each arch seat is arranged between two outer positioning blocks on the upper cover plate. The downward-opening type positioning device for the segmented mold arch seat is characterized in that each arch seat is co-positioned by an inner positioning block in the middle part and two outer positioning blocks at two sides and is not easy to move. With the downward-opening type positioning device, the problem of positioning of a segmented mold arch seat of an engineering giant wheel can be effectively solved; and meanwhile, the problems that an engineering giant tyre is thick in local rubber side and broken in figures are solved and the appearance quality of the tyre is improved. The downward-opening type positioning device with the structure is simple in processing and convenient in operation. Experiments demonstrate that the downward-opening type positioning device with the structure has the characteristics that quality tire in which the problems that the engineering giant tyre is thick in local rubber side and broken in figures exist are greatly reduced, the waste is reduced and remarkable economic benefits are obtained.

Description

technical field [0001] The invention relates to a novel bottom-opening movable mold bow seat positioning device. Background technique [0002] The mold used for the vulcanization of engineering giant tires is a bottom-opening movable mold, which is composed of a centripetal mechanism and a cavity. The cavity is composed of fan-shaped blocks, upper and lower side plates, accessories, etc. sets etc. The working principle is: the upper cover plate and the upper side plate are fixed on the upper fixing plate of the vulcanizing machine, and the middle mold cover is fixed on the lower bottom plate of the vulcanizing machine. And the lower side plate goes down together with it, the slider moves along the guide chute, closes each other, and forms a cavity with the upper and lower side plates; when the mold is opened, the upper side plate rises with the upper beam of the vulcanizing machine, and the movable mold cylinder lifts the lower side plate And the slider, push the slider to...

AI Technical Summary

Problems solved by technology

Due to the thick carcass and deep pattern of the engineering giant tire, and the pressure of the vulcanizing machine is relatively high, during the use, the pattern blocks move and concentrate on one side, causing the gap between one pattern block and the pattern block to be too large, resulting in a corresponding The rubber side of the tire is too thick here, and there are many wrong flowers
