Abstract
In a blow molding machine comprising a preform station having arranged thereon at least one extruder including at least one downstream parison head, comprising at least one blowing station on which a blowing device is arranged with at least one blowing and calibrating mandrel, and at least one mold system having a blow mold arranged underneath the at least one parison head to accommodate the thermally plasticated parison extruded out of the at least one parison head between the opened mold halves, the blow mold being moved into the blowing station after the mold halves have been closed, wherein the blowing station is arranged in front of the preform station and in parallel with the mold system.
Claims14
A blow molding machine comprising:
- a preform station having arranged thereon at least one extruder including at least one downstream parison head,
- at least one blowing station on which a blowing device is arranged with at least one blowing and calibrating mandrel, and
- at least one mold system having a blow mold having two mold halves, the blow mold arranged underneath the at least one parison head to accommodate a thermally plasticated parison extruded out of the at least one parison head between the opened mold halves, the blow mold being moved into the blowing station after the mold halves have been closed,
- wherein the at least one blowing station is arranged frontally in front of the preform station and in parallel with the mold system.
A method for manufacturing hollow articles by blow molding, wherein, after receiving at least one thermally plasticated parison, the at least one blow mold of a blow molding machine is moved on a preform station vertically or obliquely relative to its mold-parting plane to at least one blowing station arranged frontally in front of the preform station.
