Abstract

1479877 Foundary moulding HEINRICH WAGNER MASCHINENFABRIK 1 April 1976 [14 April 1975] 13245/76 Heading B3G A two-part casting box in which sand is compacted by reduced pressure comprises a drag 2 with four sides and a sieve trough 7 spaced from the sides with an opening 15 communicating with a closable opening 13; a pipe 16 leads to a vacuum source. The drag is placed on a plastics film 6 covering a pattern 5 and filled with sand from a pipe 18; the opening is closed and reduced pressure applied. After inverting the drag, a sand compacted cope, with its sand covered by films, is placed thereon and casting effected. After solidification of the casting the vacuum is released and the drag opening cleared to empty the sand.
