Abstract

1481777 Foundry pattern BUDERUS SCHE EISENWERKE 25 July 1975 [2 Aug 1974] 31251/75 Heading B3G A foundry pattern 1 for the production of moulds by the application of vacuum is of gaspermeable material whereby a plastics sheet 4 is drawn on to the pattern by vacuum applied through a hollow pattern plate 3 after which a mould box is located on the sheet, sand is supplied to the box which is then covered with a plastics sheet 7 and a vacuum applied to the box interior via a connection 8. The thus formed mould half is lifted from the pattern after disconnecting the vacuum applied to the pattern plate. The pattern may be produced from sand bonded with synthetic resin.
