摘要： 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.

摘要： A mold tool includes: a first tool part and a second tool part that works together with the first tool part. In the closed state, the two tool parts are moved toward one another, and in the open state, the two tool parts are moved away from one another. The mold tool also includes a first mold half in the first tool part and a second mold half in the second tool part. The two mold halves reshape the sheet of material, arranged between the two tool parts, into at least one three-dimensional article when the two tool parts are moved toward one another. The mold tool also includes a cutting device including at least one cutting element and at least one actuating device. The actuating device extends the cutting element in the direction of the sheet of material, to cut the sheet of material.

摘要： 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. On the inner surface of the hold-down device a guiding projection is formed opposite to a corresponding one of the prestretching levers, the stretching arm sliding on the guiding projection during movement of the prestretching structure into the mold cavity in such a way that the stretching arm is pivoted outward.
摘要翻译： 用于从加热塑料膜制造杯形模制件的热成型工具包括上工具和下工具，所述上工具和下工具可相对于彼此移动以在其间夹紧塑料膜。 在下部工具中形成用于从塑料膜形成模制部件的至少一个模腔，并且可以在压紧装置内的上部工具中设置可移动到相应的模腔中的至少一个预拉伸结构。 预拉伸结构包括至少两个预拉伸杆，其可围绕相关联的枢转轴线枢转，该预拉伸杆位于垂直于预拉伸结构的运动方向延伸的平面中。 每个预拉杆具有向下延伸的拉伸臂和向上延伸的止动臂。 在压紧装置的内表面上，引导突起形成为与预拉伸杆相对应的引导突起，拉伸臂在预拉伸结构移动到模腔中时在引导突起上滑动，使得拉伸 手臂向外枢转。
