Abstract: This mould (12) for vulcanizing a green tyre has an overall shape that is annular about an axis of revolution (X) and comprises means (28) for routing a heat-transfer liquid in a substantially circular path about the axis. The routing means (28) comprise an annular wall (36) around the axis (X), separating at least two chambers (38, 40) in which the heat-transfer liquid circulates. Furthermore, a downstream end (38A; C1A to C4A) (and respectively an upstream end 38B; C1B to C4B) of one of the chambers (38; C1 to C4) has substantially the same angular position with respect to the substantially circular path as the downstream (or respectively upstream) end of the other of the chambers (40; C1 to C4). The mould (12) additionally comprises means (52, 58A, 60B) for circulating the liquid in opposite directions in the two chambers (38, 40).
