Giant tire activating mold

Abstract

The invention relates to a fixed connection push board of a lower mold plate of a giant tire adjustable mold. The bottom parts of various patterned mold blocks are articulated with a slide block which is arranged between the lower mold plate and the push board and is embedded in a radial slide groove; and a link rod is articulated with a lower mold sleeve at the back of various patterned mold blocks. The patterned mold block back is provided with an upper inclined plane and a lower inclined plane or an upper inclined arc surface and a lower inclined arc surface, and an upper mold sleeve and the lower mold sleeve are provided with an upper fixing ring and a lower fixing ring of an inner polygonal cone surface which is matched with the upper inclined plane and the lower inclined plane or provided with an upper cone surface and a lower cone surface which are matched with the upper inclined arc surface and the lower inclined arc surface. When the mold is locked, the push board and the lower mold plate drive the slide block and the patterned mold block to move downwards; the patterned mold block controlled by the link rod withdraws downwards and inwards to closely contact the tire surface periphery; the slide block connected with the bottom end slides inwards along the slide groove; the upper mold sleeve move downwards to press the patterned mold block to further withdraw downwardsand inwards and an spigot of the upper mold sleeve and the lower mold sleeve are closed; and then the mold locking is completed. Then the mold is opened by a reverse movement. The adjustable mold meets the requirements of giant tire sulfuration and shaping and is applicable in sulfuration machines and sulfuration tanks; the patterned mold block moves flexibly and accurately, which guarantees the quality of sulfuration and shaping.

Description

(1) Technical field [0001] The invention relates to a tire flexible mold, especially a giant tire flexible mold. (2) Technical background [0002] The tire active mold is the key equipment for tire vulcanization. The active mold includes an upper mold, a lower mold and a radially movable pattern module. Giant tires have large diameters, wide sections, and deep patterns, and the size and weight of their molds have also increased accordingly. For a flexible mold with a general structure, the weight of a pattern module is nearly one ton, which makes the operation force of the mold open and close large and difficult to move. Therefore, this active mold can only be applied to vulcanizing machines, but not to vulcanizing tanks. (3) Contents of the invention [0003] The purpose of the present invention is to design a giant tire flexible mold, the pattern module of which is installed on the lower mold, which can move flexibly in the radial direction, and the centering of the mo...

AI Technical Summary

Problems solved by technology

Usually, the weight of a pattern module is nearly one ton for the active mold with a structure, which makes the operation force of the mold open and close large and difficult to move.

Therefore, this flexible mold can only be used for vulcanizing machines, not for vulcanizing tanks
