A set of moulding elements, designed to be inserted into a mould for moulding a tyre, comprises: at least one first moulding element () and one second moulding element, each moulding element extending in a main moulding-element direction (EM) between two ends () of the moulding element with one of the ends () of the first moulding element connecting to one of the ends () of the second moulding element along an axis (MA), which is substantially perpendicular to the main moulding-element axis (EM).

Set of molding elements for tire mold

A mould for vulcanizing a blank tire has an overall shape that is annular about an axis of revolution and includes a configuration for channelling a heat-transfer liquid in a substantially circular path about the axis. The channelling configuration includes an annular wall around the axis, separating at least two chambers in which the heat-transfer liquid circulates. Furthermore, a downstream end (respectively an upstream end) of one of the chambers has substantially the same angular position with respect to the substantially circular path as the downstream (respectively upstream) end of the other of the chambers. The mould is additionally configured for circulating the liquid in opposite directions in the two chambers.
