Abstract

The invention relates to a radial tire segmented mold capable of evenly vulcanizing a tire crown and solves the problem that the radial tire crown is uneven in vulcanization. The radial tire segmented mold comprises an annular base (1), an annular lower side plate (2), an annular upper side plate and an annular upper cover (4) and is characterized in that a transverse partition (12) is disposed in a sealed annular vulcanizing heating steam chamber (10), the transverse partition (12) separates the sealed annular vulcanizing heating steam chamber (10) into an annular upper steam chamber (14) and an annular lower steam chamber (15), an upper vertical partition (11) is disposed in the annular upper steam chamber (14), a lower vertical partition (13) is disposed in the annular lower steam chamber (15) right below the upper vertical partition (11), the outer lateral wall of the annular upper steam chamber (14) on the left of the upper vertical partition (11) is provided with a steam inlet (18), the outer lateral wall of the annular lower steam chamber (15) on the left of the lower vertical partition (13) is provided with a steam outlet (17), and a hole (16) communicating the upper steam chamber and the lower steam chamber is formed in the transverse partition (12) on the right of the upper vertical partition (11). By the radial tire segmented mold, the radial tire crown is evenly heated during vulcanization.

Description

technical field [0001] The invention relates to a vulcanization mold, in particular to a movable mold for vulcanizing the crown of a radial tire. Background technique [0002] The active mold is a heating mold used for vulcanizing radial tires. There is an annular steam chamber in the mold that can pass through the heating steam. The heating steam enters the annular steam chamber from the inlet, and flows out from the outlet after a circle to realize the heating of the mold. Vulcanization of the radial tire crown. This heating vulcanization form of steam one-way circulation, due to the rapid loss of steam heat in the one-way circulation steam circuit, makes the steam high at the entrance and drops a lot at the exit. The rapid change of the temperature of the heat medium leads to The uneven heating and vulcanization of the crown of the radial tire causes over-vulcanization of the tire at the steam inlet and under-vulcanization of the tire at the steam outlet, which affects t...
