Abstract
A tire mold for processing a green tire includes a movable block, an upper sidewall plate, and a lower sidewall plate. A curved surface corresponding to the green tire is provided at a junction of the movable block and the upper sidewall plate/the lower sidewall plate. The movable block, the upper sidewall plate and the lower sidewall plate cooperate with each other to surround a tire cavity for accommodating the green tire. Thereby, the edge of the upper sidewall plate or the lower sidewall plate won't penetrate the green tire to form a joint fin when the mold is closed, which is beneficial to save the rubber material, improves production efficiency and reduces manufacturing costs.
