A one-piece mold bottom (7) for a mold (1) for manufacturing containers, includes a molding wall (8) having a raised molding surface (9) bearing the imprint of at least one portion of a container bottom. The mold bottom (7) includes a cavity (27) integrally formed with the mold bottom (7), defined by a surface casing (29) defined entirely by the mold bottom (7) and including an inner surface (31) of the molding wall (8), opposite the molding surface (9) and matching the raised pattern thereof, and a rear surface (32, 33) opposite the inner surface (31). The mold 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.
One-piece mold bottom (7) designed for a mold (1) for the manufacturing of containers by blow molding or stretch blow molding from preforms made of plastic material, with this mold bottom (7) comprising a molding wall (8) that has a raised molding surface (9) bearing the imprint of at least a portion of a container bottom, with this mold bottom (7) comprising a cavity (27) enclosed in the mold bottom (7), with this cavity (27) being delimited by a surface casing (29) integrally defined by the mold bottom (7) and enclosing an inner surface (31) of the molding wall (8), opposite to the molding surface (9) and conforming to the raised pattern of the latter, and a rear surface (33) opposite the inner surface (31), with the mold bottom (7) being equipped with at least one intake opening (35) and at least one discharge opening (37) for the circulation of a coolant in the cavity (27), wherein the rear surface (33) is carried by a secondary wall (38) that joins the molding wall (8) to a peripheral edge (39) of the mold bottom (7).
