A blow molding tool () for producing a plastic article, in particular a fuel tank, comprising at least one clamping frame () with mold clamping devices () and at least two blow mold halves, which are formed such that they can be moved together and apart by means of an opening and closing movement of the clamping frame () and which respectively have at least one cavity () for the forming of the plastic article, the blow molding tool () being distinguished by the fact that the mold clamping devices () respectively have at least one tool holder (), in which a mold insert () is in each case exchangeably inserted, and in that the tool holders () respectively form a peripheral sealing edge ().

Blow molding tool and method for producing extrusion blow molded plastic articles

The invention refers to a method for the production of hollow bodies from thermoplastic, in particular for the production of motor vehicle tanks, in which the plastic is shaped as an extruded preform in the still plastic state or as a semi-finished product into at least two shells with the aid of at least one molding die (), with the use of heat, and the subsequently cooled and then dimensionally stable shells are placed one on the other and joined together into an essentially closed hollow body. As molding die () is used at least one positive die which has essentially the contour of the shells. The shells are shaped by the plastic being laid against the positive die. The apparatus for carrying out the method is also disclosed.
