Anti-dislocation device for vulcanizing machine forming mold

Abstract

The invention relates to the field of vulcanizing equipment, in particular to an anti-dislocation device for a vulcanizing machine forming mold. An upper plate mold and a bottom plate mold both for molding a workpiece are separately and fixedly arranged on the vulcanizing machine; a medium plate mold which matches with both the upper plate mold and the bottom plate mold is movably arranged betweenthe upper plate mold and the bottom plate mold in push-and-pull mode; a positioning opening groove A is formed in one side of the medium plate mold; a guiding column, positioned at one side of the positioning opening groove A, is hinged with a positioning plate matching with the positioning opening groove A; the positioning plate is positioned right above the positioning opening groove A when themedium plate mold is in matching state with the upper plate mold and the bottom plate mold; and a proximity switch used for controlling start-stop state of a jacking hydraulic cylinder is arranged below one end, away from the medium plate mold, of the positioning plate. By means of the anti-dislocation device for the vulcanizing machine forming model, the occurrences of failure of hot melting molding of a rubber workpiece and damage of the mold due to the fact that the medium plate mold is not pushed in place in a traditional art are avoided, and the work efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of vulcanizing machine equipment, in particular to an anti-displacement device for a molding die of a vulcanizing machine. Background technique [0002] When using a vulcanizer to heat-melt a rubber workpiece with a relatively complex structure, in order to prevent the occurrence of "bubbles" during the hot-melt molding process, the forming mold is composed of multiple plate molds, so that the gas in the rubber raw material after hot melting For this reason, in the traditional technology, every time the vulcanized rubber workpiece is vulcanized, the forming mold needs to be disassembled and assembled. This method is slow in processing efficiency, and it is easy to misplace or miss the plate mold. [0003] In order to solve this problem and improve processing efficiency, some manufacturers currently fix the upper plate mold and the lower plate mold on the heating plate and lifting platform of the vulcanizer respectivel...

Problems solved by technology

[0004] However, in the actual production, it was found that due to the high work intensity, the position of the operator pushing the middle plate mold was not in place, and the middle plate mold did not match the upper plate mold and the lower plate mold, resulting in the failure of hot-melt molding of the rubber workpiece Occurs, increasing the waste of raw materials, reducing production efficiency, and even causing damage to the formwork in severe cases
