Abstract: A thermoforming mould for producing cup-shaped articles from a heated film of plastic is provided. The thermoforming mould comprises a first mould part and a second mould part which are movable in relation to one another, wherein at least one cavity for moulding a cup-shaped article is formed in one of the two mould parts. The thermoforming mould also comprises a measuring device which is designed to determine a tilting of the first mould part and the second mould part with respect to one another. Furthermore, a thermoforming machine comprising the thermoforming mould and also a method for determining a tilting between a first mould part and a second mould part of a thermoforming mould are provided.
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).

Abstract: A thermoforming tool for producing cup-shaped molded parts from a heated film of plastic includes an upper tool and a lower tool, which are movable in relation to each other for clamping the film of plastic therebetween. At least one mold cavity for forming a molded part from the film of plastic is formed in the lower tool and at least one prestretching structure movable into a corresponding mold cavity is arranged in the upper tool inside a hold-down device. The prestretching structure includes at least two prestretching levers pivotable about an associated pivot axis, which lies in a plane running perpendicularly to the direction of movement of the prestretching structure. Each of the prestretching levers has a stretching arm extending downward, and a stop arm extending upward.
