发明名称 Process and extrusion blow-moulding machine for producing plastic containers
摘要 Process for producing plastic containers, including an extrusion blow molding machine, is disclosed. For example, in an extrusion blow molding process for plastic bottles, in which plastic tubing (T) which has been extruded from an extruder head in a definable cycle is placed in the mold cavity of a blow molding tool arrangement, the inserted plastic tubing is inflated via an infeed blow mandrel by overpressure according to the mold cavity and is then removed from the mold. The extruded plastic tubing (T) is inserted into a mold cavity which is composed of several blow mold cavities which are located axially under one another, two of the blow mold cavities at a time being arranged mirror-symmetrically to one another and connected on their mouth regions and an individual blow mold cavity being separated from the bottom section of the adjacent blow mold cavity by a land region and having a mouth on the outer surface of the blow molding tool arrangement. There is a number of guided blow mandrels corresponding to the number of pairs of blow mold cavities located mirror symmetrically to one another. The containers (B) which have been inflated according to the blow mold cavities are removed from the mold.
