Abstract:
1. A machine for moulding containers ( 3 a ) made of plastic material, comprising an assembly ( 2 ) for extruding tubes ( 3 ) of plastic material, a blowing assembly ( 5 ), a mould for containing containers ( 3 a ) formed by two half-moulds ( 4 a, 4 b ) 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 ( 4 a, 4 b ) in the longitudinal direction are of the electric type, and means ( 110 ) for symmetrically adjusting the distance of the two half-moulds ( 4 a, 4 b ) from said fixed axis (Z—Z), wherein said means ( 110 ) for adjusting the relative distance of the two half-moulds ( 4 a , 4 b ) comprise a sleeve ( 112 ) which is parallel to the longitudinal direction (X—X) and a first end of which is joined to the rod ( 105 b ) actuating the front carriage ( 106 b ) and the other end of which is constrained to the base of the said carriage ( 106 b ) by means of a screw/internal thread coupling ( 112 a ).
