<p>The invention is a new rotary support structure for moulds, with circular or annular rotating plane (O2), on which various moulds are installed (S), said structure being equipped with a single mould opening mechanism (U 1a, U 1b) and a single mould closing mechanism (U2a, U2b). On the circular plane (02), at the level of each pair of mould halves (Sa, Sb), there are several locking devices (C) that slide radially and are formed by two elements (C1, C2) with opposing C-shaped sections constrained to each others. The upper half of the mould (Sa) is integral with one or more sliding rods (Bs) generically orthogonal to the circular or annular plane (O) and having the lower end provided with a sliding block (Bp) suited to slide on a rail (F5) positioned below the circular or annular plane (O).</p> |
