Claim:
Molding device for a machine for producing thermoplastic material containers, by blowing or drawing-blowing a preform, the molding device including: two half-molds each of which is provided with a half-imprint and each of which includes a front joint face and a rear face; two mold-carriers each of which is provided with a recess intended to receive an associated one of said half-molds in a mounted position in which the rear face of the half mold is in contact with a bottom of the recess; and at least one retractable fixing bolt that is slidably mounted in at least one of said mold-carriers to slide between an active position in which said fixing bolt is extended to fix in demountable manner the associated half-mold in the mounted position clamped against the bottom of the associated recess by at least one locking face of each fixing bolt bearing against an associated fixing face of the half-mold, and a retracted position in which said fixing bolt releases the half-mold, each fixing bolt includes a clamping ramp that is inclined in such a manner as to press the half-mold against the bottom of the recess on sliding of said fixing bolt from said retracted position to said active position, characterized in that the recess has an entry in a transverse plane that is delimited transversely by a vertical first edge and a vertical second edge, and in that each fixing bolt is mounted to slide transversely between said active position in which said fixing bolt projects through the entry of the recess and said retracted position in which said fixing bolt is completely retracted relative to the entry of the recess.
