Method and tool for producing a plastic container, particularly a fuel container, by internal pressure forming

A method for producing a plastic container by internal pressure of a tubular preform and subsequent displacement of components of a molding tool relative to each other thereby to produce two halves of the plastic container, the method comprising:

• disposing the tubular preform between two mold parts of the molding tool, the two mold parts being configured to provide a mold cavity that is surrounded by at least one chamber, wherein the two mold parts are movable relative to one another;
• and
• closing the two mold parts of the molding tool to perform molding or pre-molding of the tubular preform to form the container by internal pressure, wherein the tubular preform is disposed between the two mold parts,
• wherein a resulting encircling portion of the preform is pushed through a mold gap into the at least one chamber that surrounds the mold cavity, wherein, thereby, in this at least one chamber, the resulting encircling portion is pressed against a plurality of claw pairs that are positioned in the at least one chamber, wherein the claw pairs are disposed about the mold cavity, wherein the plurality of claw pairs include stationary inner holding claws and movable outer tearing claws such that the outer tearing claws are laterally displaced, wherein the lateral displacement of the pair of outer tearing claws is perpendicular to a movement direction of the mold parts, and,
• wherein, thereafter, and on account of the lateral displacement of the pair of outer tearing claws, the encircling portion is torn between the pair of outer tearing claws and the pair of inner holding claws, whereby the produced container is divided into two container halves.
