Abstract

The invention relates to the field of tire die structures, aims to solve the problem of a safety accident caused by easy damage to a guide strip and a limiting block during die opening of a tire die in the prior art, and provides a tire loose die limiting mechanism and a tire loose die. The tire loose die limiting mechanism comprises a guide ring, an upper cover and multiple sliding pieces, wherein the tire loose die limiting mechanism is used for limiting the upper cover during die opening; the tire loose die limiting mechanism further comprises multiple limiting pieces which are connected tothe guide ring and are distributed along the circumferential direction of the guide ring; the limiting pieces are located in gaps between adjacent sliding pieces of the tire loose die limiting mechanism; and the upper cover of the tire loose die limiting mechanism is provided with a limiting surface corresponding to the limiting pieces along the axial direction of the guide ring. The tire loose die limiting mechanism disclosed by the invention has the beneficial effects that limitation to the upper cover during opening of a die can be realized; stress on a limiting block is reduced and even is not needed, so that problems of falling off of the upper cover, breakage of the guide strip and the like due to the stress on the limiting block are reduced; and the potential safety hazard is reduced, and the safety coefficient is increased.

Description

technical field [0001] The invention relates to the field of tire mold structures, in particular to a tire active mold limiting mechanism and a tire active mold. Background technique [0002] The tire flexible mold is the equipment for tire molding and vulcanization. The flexible mold of automobile tire is opened and closed by the guide structure and the driving pattern part. The mold includes an upper-opening structure, a two-half active structure, etc. In these structure molds, in order to realize the opening and closing of the mold, there is a guide bar between the mold guide structure and the pattern part. Through the guiding function of the guide bar, the force of the vulcanizer drives the guide structure to move upward, and the pattern part moves outward to realize the opening and closing of the entire mold, thereby taking away the formed tire. During this process, the tire active mold needs to limit the mold opening and closing stroke, so as to avoid problems such a...
