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.
