Blow molding machine

A blow molding machine, comprising:

• a frame;
• a blow mold adapted for receiving a tubular parison and having a first mold support plate for support of one mold half and a second mold support plate for support of another mold half;
• a transport unit mounted to the base frame and operatively connected to the blow mold, said transport unit including a first drive for movement of the first support plate and a second drive for movement of the second support plate independent of the first drive so as to allow displacement of the blow mold halves independently from one another;
• and
• a locking mechanism secured to the support plates for pinching off the tubular parison and clamping the mold halves during the blow molding operation.

A blow molding machine, comprising:

• a frame;
• a pair of outer support plates mounted to the frame, each carrying a blow mold half;
• at least one inner support plate mounted to the frame and carrying on one side a blow mold half for interaction with the blow mold half of one of the outer support plates an don the other side a blow mold half for interaction with the blow mold half of the other one of the outer support plates;
• a drive mechanism so operatively connected to the outer support plates as to allow a displacement of the outer support plates independently from one another while the inner support plate is freely movable on the frame;
• and
• a locking mechanism provided between the inner support plate and the outer support plates for effecting a displacement of the inner support plate with respect to the outer support plates independent from a displacement of the outer support plates.
