Abstract
A molding tool (1000), in particular a thermoforming tool, for producing a container (10) is provided. The molding tool comprises a mold bottom (200) and a mold insert (100) receiving the mold bottom (200), wherein the mold insert (100) is constructed of at least two mold insert parts (110, 120) that together with the mold bottom (200) define a cavity (300) provided for reshaping a two-dimensional web of material into a container, wherein a first mold insert part (110) is mounted stationary in the molding tool (1000) and a second mold insert part is axially movable in the molding tool (1000).
Claims20
A molding tool, in particular a thermoforming tool, for producing a container, comprising a mold bottom and a mold insert receiving the mold bottom,
- wherein the mold insert is constructed of at least first and second mold insert parts that together with the mold bottom define a cavity provided for reshaping a two-dimensional web of material into a container,
- wherein the first mold insert part is mounted stationary in the molding tool and the second mold insert part is mounted axially movable in the molding tool.
(canceled)
A method for producing a container from a two-dimensional web of material, wherein the method comprises the following steps:
- providing a molding tool, wherein the molding tool comprises a mold bottom, a first mold insert part, and a second mold insert part which form a cavity having a mold side wall;
- positioning the second mold insert part and the mold bottom of the molding tool in a molding position in order to permit molding of the container;
- molding the container in that a two-dimensional web of material is molded in the cavity of the molding tool until said web of material is positioned against the mold bottom and mold side wall of the mold insert part;
- and,
- axially moving the mold bottom and the second mold insert part relative to the first mold insert part in order to demold the container in the cavity.
