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 method of vacuum forming an object includes heating a plastic sheet. After heating the plastic sheet, a vacuum is applied to pull the sheet against an outer surface of a flexible mold so that the plastic sheet has a formed shape that conforms to a contoured shape of the outer surface of the flexible mold. A rigid core is withdrawn from a cavity in the flexible mold. The flexible mold is then withdrawn from the plastic sheet by applying force to the flexible mold in a single direction, thereby causing flexing of the flexible mold past the undercut. An apparatus for vacuum forming a plastic sheet includes the flexible mold.

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： A sheet of plastics material is continuously extruded onto the upper run of an endless conveyor which carries aluminum vacuum mold plates each defining a cavity with a shingle pattern. The sheet is progressively vacuum-formed into the mold plate cavities, and opposite longitudinal upper and lower portions of the sheet are progressively vacuum-formed, with traveling plug assist in one embodiment, to define shingle panels with hook-shaped lower portions and upper portions defining grooves for receiving the lower portions. The upper portion of the sheet is punched with longitudinally spaced slots to form a nailing flange, and the sheet is then cut laterally at longitudinally spaced intervals to produce elongated siding panels each having integrally connected shingle panels. The shingle panels may have different bottom configurations or profiles and are interchangeable.

摘要： A modular, vacuum formed, unitary vanity which extends from floor to the ceiling, or near the ceiling. Alternatively, the vanity extends upwardly from the counter top level to the ceiling. The vanity is vacuum formed of a single piece of formable material, such as acrylic. The vanity has no joints or seals to deteriorate with use and time or to collect dirt. The modular and unitary vanity fits within a void formed in a wall during construction. The device is substantially maintenance free in ordinary use. The vanity is vacuum formed from a single piece of formable material using a vacuum form mold. The mold is a break apart mold which allows the vanity to be removed from the mold without interference from the sink bowl which is formed in the vanity.
