Beschreibung
Zusammenfassung:	A machine (10) for blow molding containers (110). The machine (10) has a stationary flow head (26) located above a turntable (12) with molds (16) mounted on carriages (38). The carriages (38) are mounted on ramps (40) and are raised to remove containers (110) and are lowered from the flow head (12) using a closed loop hydraulic system actuated by a cam. A double rack-and-pinion assembly (78) guides opening and closing of the molds (16) and a locking system having locking shafts (94, 96) engaging apertures (98, 100) in a cross head (74) with pivoting locking keys (102, 104) movable into alignment with the apertures (98, 100) prevents inadvertent mold opening. A container transfer device (32) has inflatable bladders (140) which engage the interior of the containers (110) to prevent damage. Augmented cooling of the containers (110) in the mold (16) is provided by positioning the flow head (26) at an acute angle (28) to the transfer device (32). Different molds (16) may be positioned on the turntable (12) in an alternating arrangement to facilitate production changeover.
