Abstract

The invention concerns a mold tool for the production of extrusion blow molded products, comprising at least three mold portions (2a, 2b, 3) which define a mold cavity (4) and of which two are in the form of outer molds (2a, 2b) and one is in the form of a central mold (3). The outer molds (2a, 2b) and the central mold (3) are displaceable from and towards each other in the sense of an opening and closing movement of the tool. The central mold (3) is provided with component holders (11) which can be moved out of and into the tool plane defined by the central mold and are arranged in turn on a carrier (10) which is also displaceable with respect to the central mold (3).
