Abstract
A device for blow-molding or stretch blow-molding of thermoplastic material performs, the mold including two half-molds and a mold base mutually mobile through actuating devices controlled by a fixed cam. A link rod device with three degrees of freedom in rotation is provided between one half-mold such that upon opening the two half-molds are spaced apart from each other without moving the base, then so that the base moves axially while the two half-molds continue to be mutually and completely spaced apart, and vice-versa.
