Blow-molding machine comprising a closing and locking mechanism

Machine for blow-molding thermoplastic products, of the type in which a molding unit (10) comprises a mold made of two parts where each is carried by a mobile support (12), of the type in which the two mobile supports (12) are hinged in relation to each other, of the type in which the movements of the two supports (12), between an open position and a closed position, are controlled by a mechanism that comprises a traveling slide (16) between an opening position and a closing position, of the type in which each support (12) is connected to the slide (16) by at least one associated connecting link (36) that is hinged on the one hand to the slide (16) and the other hand to said support (12), of the type in which, in the closed position, the main axes of the connecting links (36), which are each determined as being a common perpendicular to the hinge axes of the connecting link (36) on the slide (16) and on the associated support (12) are oriented in a same direction perpendicular to the hinge axis (A1) and perpendicular to a joint face of the mold parts, so that the control mechanism ensures the locking of the molding unit in the closed position,

• characterized by the fact that, in the closed position, the main axes of the connecting links (36) are arranged in a median plane of the part of the mold that is carried by the associated support, and
• characterized by the fact that the molding unit (10) is integral with a carousel with a continuous rotation movement, and by the fact that the slide (16) is controlled by a device with a cam (42) and a cam follower (44).
