Vacuum duct for feeding mold piece from exterior into interior of vacuum chamber, has housing comprising upper ad lower parts with opening in geometry of mold piece at defined distance to external dimensions for feeding mold piece

摘要

The duct has a sealing carrier (5) arranged in a hollow cavity (4) in an axial movable manner. A sealing (7) is arranged between the carrier, an upper part (2) i.e. cover and a lower part (3) i.e. flange, of a housing (1) in a form-fit manner. The sealing encloses a moldpiece (8) in a tight manner. The sealing is designed in external dimensions such that the sealing seals the carrier against the parts in an assembled condition. The parts of the housing have an opening in geometry of the mold piece at defined distance to the external dimensions for feeding the mold piece.
