MULTI-CHAMBER TIRE MANUFACTURING MOLD

A multi-chamber tire manufacturing mold, comprising an upper holding plate (11) and a lower holding plate (13) having an interval between the upper holding plate (11) and the lower holding plate (14); a tire periphery forming slider (16), a tire inner chamber forming slider (17), an upper mold block (121), a lower mold block (122), and a central mold post (18) are arranged in the interval; the upper holding plate (11) is connected to the plurality of upper mold blocks (121), and the lower holding plate (13) is connected to a plurality of lower mold blocks (122), forming an enclosed chamber (10); the tire inner chamber forming slider (17) is arranged in the enclosed chamber (10), forming a flexible portion chamber (101) and a partitioned chambers (171), such that a plurality of isolating chambers (25) are formed in the flexible portion (21); the openings of the isolating chambers (25) together with the tire periphery forming slider (16) form an enclosed chamber via process sealing members and fill the forming outer body (22). A tire flexible portion manufactured by the mold is provided with a plurality of enclosed isolating chambers, and can withstand multiple punctures and still meet the demands of high-speed run, thus the service life and performance of the tire are improved.
