Device for blow-molding containers

A device for blow-molding containers, the device comprising a structure (1) and a platform (2) mounted to rotate on the structure about an axis of rotation (3), the platform being provided with blower members (4) and with molds (5) that are mounted under the blower members, each of which comprises a stationary mold portion (6) and a movable mold portion (7) that is movable in pivoting by control means (12, 13) between an open position and a closed position for the mold, the device being characterized in that it includes blocking members for blocking the molds in the closed state, each blocking member comprising a strut (11) that is connected to the movable mold portion by at least one link and that is secured to a pivot shaft (12) mounted on the platform to move between a retracted position and a blocking position in which the strut is in contact with a surface secured to the movable mold portion, the pivot shaft (12) being positioned in such a manner that in the closed position the strut extends in a direction (F) along which a resultant of the blow-molding force as taken up by the movable mold portion is applied.
