MULTI-PART BLOW MOULD, METHOD FOR PRODUCING A HOLLOW BODY, HOLLOW BODY AND EXTRUSION BLOW MOULDING MACHINE

摘要

The invention relates to a multi-part blow mould for producing a blow-moulded hollow body, comprising a first one-piece tool segment (13) having an axial passage (31) provided with a first and a second opening (33, 35). Said passage (31) defines a first cavity (37) for forming a seamless hollow body section. A second two-part tool segment (15) is arranged on the first opening (33) of the passage (31), defining a second cavity (19) in the blow-moulding position and is used to form the head part of the hollow body. A third two-part tool segment (17) is arranged on the second opening (35) of the passage (31), defining a third cavity (21) in the blow-moulding position and is used to form a base of the hollow body. The three cavities together define the shape of the hollow body that is to be produced.
