Electrically actuated blow-moulding machine

A machine for moulding containers (3a) made of plastic material, comprising an assembly (2) for extruding tubes (3) of plastic material, a blowing assembly (5), a mould for containing containers (3a) formed by two half-moulds (4a, 4b) movable upon actuation of associated first means (100), in a longitudinal direction (X—X) and symmetrically with respect to a fixed axis (Z—Z) perpendicular to said longitudinal direction, the assembly formed by the mould (4) and the associated first actuated means (100) being movable, upon actuation of second actuating means (200), in a transverse direction (Y—Y) from a position corresponding to the extrusion assembly to a position corresponding to the blowing assembly and vice versa, said first means for actuation of the half-moulds (4a, 4b) in the longitudinal direction are of the electric type, and means (110) for symmetrically adjusting the distance of the two half-moulds (4a, 4b) from said fixed axis (Z—Z), wherein said means (110) for adjusting the relative distance of the two half-moulds (4a, 4b) comprise a sleeve (112) which is parallel to the longitudinal direction (X—X) and a first end of which is joined to the rod (105b) actuating the front carriage (106b) and the other end of which is constrained to the base of the said carriage (106b) by means of a screw/internal thread coupling (112a).
