    摘要： A molding tool and a method for producing molded parts from a moldable material with a first tool component and a second tool component are described. The first tool component has a cavity with a first molding surface and the second tool component has a second molding surface and a flexible material forming at least one portion of the second molding surface. In a first step, a moldable material is introduced into the cavity and then the second tool component is moved into the cavity. A second molding surface of the second tool component moves the moldable material in regions against the first molding surface. Thereafter, overpressing of the second tool component takes place after reaching a bottom dead center within the cavity, whereby the flexible material is deformed and presses the moldable material against a corresponding portion of the first molding surface.

    摘要： 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).

    摘要： A crisscross thermoforming assist plug assembly having a pair of oppositely outwardly facing thermoforming assist plugs each carried by a respective one of a pair of thermoforming assist plug linkage arrangements, where at least one link of the linkage arrangement is used to extend one of the assist plugs in one direction crosses but does not contact in a side view or profile of the thermoforming assist plug assembly, and at least one link of the other linkage arrangement is used to extend the other one of the assist plugs in an opposite direction. The links of the linkage arrangement preferably pivot about a common pivot axis that preferably is an elongate pivot shaft extending transversely between elongate upper rails of a frame of the assembly. At least one of the links of the linkage arrangement is a drive link that extends or retracts one of the plugs that crosses a drive link that extends and/or retracts the other one of the plugs. The drive links preferably form a crisscross arrangement when actuated in a manner that substantially simultaneously extends the respective plugs into the mold cavity and/or substantially simultaneously retracts the respective plugs from the mold cavity.

    摘要： A pair of form keys and a method for forming reverse drafts in foam parts are disclosed. A male form key is reciprocally mounted in a first mold half in a retracted position. A female form key is rotatably mounted in a second mold half in a neutral position. The first mold half includes a first drive pin that when engaged, moves the male form key into engagement with a foam sheet to form an undercut as the first and second mold halves are closed. The first mold half also includes a second drive pin that engages the female form key as the first and second mold halves close rotating the female form key into engagement with the foam sheet and the male form key. After closure of the mold and the product is formed, the mold is opened. As this occurs, the drive pins are disengaged and the male form key retracts and the female form key rotates to their neutral positions. The formed product may then be stripped from the mold while maintaining the reverse draft or undercut. In a further embodiment the male form key and the female form key are fluid actuated.

    摘要翻译： 公开了一种形式键和在泡沫部件中形成反向牵引的方法。 阳形成钥匙在缩回位置的第一半模中相互安装。 阴形密钥钥匙可旋转地安装在中间位置的第二半模中。 第一模具半部包括第一驱动销，当第一和第二半模封闭时，第一驱动销接合时，移动凸形键与泡沫板接合，形成底切。 第一半模具还包括与第一和第二半模相接合的第二驱动销，该第二和第二半模闭合使阴形密钥键旋转与泡沫片和阳形密钥卡合。 在模具闭合并形成产品之后，打开模具。 当这种情况发生时，驱动销被分离并且凸形键缩回并且凸形键旋转到它们的中立位置。 然后可以在保持反向牵伸或底切的同时从模具剥离成形的产品。 在另一个实施例中，凸形键和凹形键被流体致动。
