A device for transporting a hollow body having a neck including an inner vertical orientation wall and a top edge, the device including elements for grasping the hollow body by engaging with the neck's inner wall, which are mounted at the bottom end of a rod and movably connected to the rod, the rod being movably mounted vertically between a high position and a low position. The grasping elements are movably mounted radially between: a retracted position, in which the grasping elements are inserted vertically, from top to bottom, inside the neck, without contact with the inner wall; and a deployed position, in which the grasping elements engage with the inner wall of the neck, wherein changing the position of the grasping elements from the retracted to the deployed position is controlled by the vertical movement toward the bottom of the rod, from the high to the low position.

Device for transporting a hollow body comprising improved grasping means

Disclosed is a molding device () for a machine for manufacturing containers, in particular bottles, made of a thermoplastic material by blow-molding or stretch blow-molding a preheated preform. The molding device () includes: two half-molds (), each of which is provided with a half-cavity () and each of which includes a sealing surface () and an outer surface (); two mold carriers (), each of which has a recess () for receiving a corresponding half-mold (); and an attachment element () for removably attaching each half-mold () into the recess () of the corresponding mold carrier (), characterized in that the attachment element () is controlled by the attraction of the half-mold () against the back wall () of the recess () of the mold carrier ().

Blow-molding device provided with means for attaching, by suction, a half-mold to a back wall of a corresponding recess of a mold carrier

A blow moulding machine () for the manufacture of containers based on preforms, includes at least one rotating turntable () furnished with a console () supporting two half-moulds () that are designed to form the body of the container and a mould base () that is designed to form the bottom of the container, of the type in which the mould base () is driven so as to slide vertically by a cam system (), characterized in that the console () includes at least one return member that forces the mould base () towards its top position, and in that the cam system () includes a cam follower element () that is slidingly connected to the mould base () and that interacts with a control surface () oriented downwards.
