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.

1. 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). 2. Mold bottom (7) according to claim 1, wherein the inner surface (31) of the molding wall (8) essentially covers the entire molding surface (9). 3. Mold bottom (7) according to claim 1, wherein the molding wall (8) has an essentially uniform thickness. 4. Mold bottom (7) according to claim 1, wherein the molding wall (8) has a thickness of between 0.5 mm and 5 mm. 5. Mold bottom (7) according to claim 4, wherein the molding wall (8) has a thickness of approximately 1 mm. 6. Mold bottom (7) according to claim 1, wherein the intake opening (35) is formed by a series of through holes (35) made in the secondary wall (38). 7. Mold bottom (7) according to claim 6, further comprising a distribution chamber (40) that adjoins the cavity (27) by being separated from the latter by a central portion of the secondary wall (38) in which the through holes (35) are made. 8. Mold bottom (7) according to claim 1, further comprising at least one collector (43) into which at least one discharge opening (37) empties. 9. Mold bottom (7) according to claim 8, wherein the collector (43) comes in the form of a peripheral annular pipe. 10. Mold bottom (7) according to claim 9, further comprising at least one drop (47) into which the collector (43) empties and which ends by a drain opening (48). 11. Mold bottom (7) according to claim 1, further comprising columns (53) and/or a three-dimensional network (R) that connects the inner surface (31) of the molding wall (8) to the rear surface (33). 12. Mold (1) for manufacturing containers from parisons made of plastic material, which comprises at least one mold bottom (7) according to claim 1. 13. Method for manufacturing a mold bottom (7) according to claim 1, which comprises a phase for obtaining a parison of the mold bottom (7) by direct fabrication from a metal powder. 14. Manufacturing method according to claim 13, wherein the parison of the mold bottom (7) is obtained by direct additive laser construction. 15. Mold bottom (7) according to claim 2, wherein the molding wall (8) has an essentially uniform thickness. 16. 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), and at least one collector (43) into which at least one discharge opening (37) empties, wherein the collector (43) comes in the form of a peripheral annular pipe. 17. Mold bottom (7) according to claim 9, further comprising at least one drop (47) into which the collector (43) empties and which ends by a drain opening (48).
