Abstract
The invention relates to a molding device for producing vessels by blowing or stretch-blowing from preforms of a heated thermoplastic material, the device including at least one mold that has at least two half-molds and a driving mechanism for moving the half-molds between an open position and a closed position. The two half-molds are hinged together for rotation about a hinge axis included in the junction plane and perpendicular to the axis of the molding cavity, the hinge axis being located under the half-molds, while a mechanism for locking the half-molds in their closed position are also provided. Each half-mold includes an outer surface area capable of abutment with an inner surface area of the mechanism for locking the half-molds in their closed position. The locking mechanism is in the form of a clamp capable of clamping the two half-molds in their closed position.
