Abstract:
1. A molding device for blow-molding or stretch-blow-molding containers from heated thermoplastic preforms, said device comprising at least one mold comprising at least two half-molds that can be moved with respect to each other between an open position in which they are parted from one another and a closed position in which they are firmly pressed against one another via collaborating respective bearing faces defining a parting line, locking means being provided to lock the two half-molds in the closed position, which locking means comprising on at least one side of the mold, a first lock element in the form of a hook secured fixedly to the first half-mold along the edge of the bearing face thereof, a second lock element in the form of a hook inverted with respect to the previous one and mounted such that it can pivot, on a rotation surface, on the second half-mold, and actuating means functionally associated with said second lock element in such a way as to move the latter transversely between a locked position in which it is engaged with the first lock element to lock the two half-molds in the closed position and an unlocked position in which it is disengaged from the first lock element to release the two half-molds that can then be parted from one another, wherein, in addition: whereby, when the mold is closed and locked and subjected to the blowing pressure, the force to which the second half-mold is subjected is reacted, by said moving part, substantially continuously over most of its height via said rotation surface.
