In order to solve the above problems, the tire segmented mold of the embodiment is used for solving the technical problem that the excessive glue amount is large due to the fact that the block groups are not closed in place.

Referring to fig. 1, the present embodiment provides a tire segmented mold, which includes a lower side plate 100, a block group 200 capable of moving relative to the lower side plate 100, a guide ring 300 slidably connected to the block group 200 and pushing the block group 200 to move laterally, and an upper cover 400 driving the guide ring 300 to move vertically; a first elastic support assembly 500 is arranged between the upper cover 400 and the guide ring 300, and the first elastic support assembly 500 can enable a first gap to be formed between the upper cover 400 and the guide ring 300 in the mold opening state of the tire segmented mold.
