Patent ID: 8794953

Claim:
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 ); and fixing 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 ).
