Abstract:
1. 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.
