Disclosed is a molding device (10) for a machine for manufacturing containers, in particular bottles, made of a thermoplastic material by blow-molding or stretch blow-molding a preheated preform. The molding device (10) includes: two half-molds (14), each of which is provided with a half-cavity (16) and each of which includes a sealing surface (18) and an outer surface (20); two mold carriers (34), each of which has a recess (40) for receiving a corresponding half-mold (14); and an attachment element (44, 52) for removably attaching each half-mold (14) into the recess (40) of the corresponding mold carrier (34), characterized in that the attachment element (44, 52) is controlled by the attraction of the half-mold (14) against the back wall (42) of the recess (40) of the mold carrier (34).

1. Molding device (10) for a machine for producing chambers, notably bottles, in thermoplastic material by blowing or drawing-blowing a pre-heated preform, the molding device (10) including: two half-molds (14) each of which is provided with a half-imprint (16) and each of which includes a joint face (18) and an external face (20);two mold-carriers (34) each of which is provided with a recess (40) intended to receive an associated half-mold (14) in a mounted position in which the external face (20) of the half-mold (14) is in contact with the bottom (42) of the recess (40), the mold-carriers (34) being provided with means for regulating the temperature of the imprint (16) by thermal conduction between the half-mold (14) and the means for regulating the temperature of the mold-carrier (34); andfixing means (44, 52) adapted to fix each half-mold (14) demountably in the recess (40) of the associated mold-carrier (34), characterized in that the fixing means (44, 52) are controlled means for aspiration by the sucker effect of the half-mold (14) against the bottom (42) of the recess (40) of the mold-carrier (34). 2. Device (10) according to claim 1, characterized in that the half-mold (14) is adapted to be mounted in and demounted from its recess by a movement in translation orthogonal to the joint face (18) of the half-mold (14). 3. Device (10) according to claim 1, characterized in that at least one airtight chamber (44) is reserved at the interface between the mold-carrier (34) and the half-mold (14) in the position mounted on the mold-carrier (34), and in that the airtight chamber (44) communicates with a vacuum source (52) via an aspiration conduit (54) to enable establishing in the airtight chamber (44) of a fixing pressure less than atmospheric pressure. 4. Device (10) according to claim 3, characterized in that the airtight chamber (44) is formed in part by a cavity that is formed in the external face (20) of the half-mold (14). 5. Device (10) according to claim 3, characterized in that the airtight chamber (44) is formed at least in part by a cavity (46) that is formed in the bottom (42) of the recess (40) in the mold-carrier (34). 6. Device (10) according to claim 3, characterized in that the airtight chamber (44) is sealed by at least one seal that is carried by the half-mold (14). 7. Device according to claim 3, characterized in that the airtight chamber (44) is sealed by at least one seal (48) that is carried by the mold-carrier (34). 8. Device according to claim 1, characterized in that the half-mold (14) includes means (64, 66) for positioning it on the mold-carrier (34). 9. Device (10) according to claim 8, characterized in that the positioning means (64, 66) are means operative via nesting of complementary shapes between the associated half-mold (14) and the associated mold-carrier (34). 10. Device according to claim 1, characterized in that the half-mold (34) is equipped with means (68) for mechanically attaching it to the mold-carrier (34) in order to enable retention of the half-mold (14) on the mold-carrier (34) on stopping the controlled fixing means (44, 52). 11. Device (10) according to claim 2, characterized in that at least one airtight chamber (44) is reserved at the interface between the mold-carrier (34) and the half-mold (14) in the position mounted on the mold-carrier (34), and in that the airtight chamber (44) communicates with a vacuum source (52) via an aspiration conduit (54) to enable establishing in the airtight chamber (44) of a fixing pressure less than atmospheric pressure. 12. Device (10) according to claim 4, characterized in that the airtight chamber (44) is formed at least in part by a cavity (46) that is formed in the bottom (42) of the recess (40) in the mold-carrier (34). 13. Device (10) according to claim 4, characterized in that the airtight chamber (44) is sealed by at least one seal that is carried by the half-mold (14). 14. Device according to claim 4, characterized in that the airtight chamber (44) is sealed by at least one seal (48) that is carried by the mold-carrier (34). 15.
