<p>The invention relates to a machine for producing containers made of thermoplastic materials by blowing, used for manufacturing containers of various shapes, by blowing the air into the preforms made by thermoplastic materials, said materials having been previously thermally conditioned. According to the invention, the machine comprises a metal frame (A) and a knuckle joint mechanism (B) by means of which there is modified the position of a mobile plate (1) in relation to a fixed plate (2), with a die (3) being located therebetween, and the actuation of the sealing-blowing heads (J-K) being achieved by means of some hydraulic cylinders, at the upper side of the metal frame (A) there being provided a vertical guiding column (13) integral with L-shaped support (12), along which a horizontal arm (D) glides by means of a sleeve (15), whereto there is articulated a rod (16) of a hydraulic cylinder (E), placed outside the shaft of the hydraulic cylinders (G and H) and with a connecting plate (24) achieving the connection between a horizontal arm (D) and some ball joints (F) integral with the connecting plate (24) at the upper side, and at the bottom side with some elongation rods (34) axially crossing the tubular rods (35 and 36) of the hydraulic cylinders (G and H).</p> |
