The invention relates to a one-piece mould bottom (7) for a mould (1) for manufacturing containers, said mould bottom (7) including a moulding wall (8) having a raised moulding surface (9) bearing the imprint of at least one portion of a container bottom. Said mould bottom (7) includes a cavity (27) integrally formed with the mould bottom (7), defined by a surface casing (29) defined entirely by the mould bottom (7) and including an inner surface (31) of the moulding wall (8), opposite the moulding surface (9) and matching the raised pattern thereof, and a rear surface (32, 33) opposite the inner surface (31). The mould bottom (7) is provided with at least one pair of openings (35; 37) leading into the cavity (27) for circulating a heat-transfer fluid inside the cavity. |
