Abstract

1,253,091. Foundry moulding machines. BAKER PERKINS Ltd. 16 April, 1970 [23 Jan., 1969], No. 3759/69. Heading B3F. [Also in Division B1] A foundry moulding machine for preparing moulds from a cold-setting sand/resin/catalyst mixture, has a mixer 7 which both forms the mixture and impels it into a mould-box 9. Sand from a hopper 1 is supplied to two horizontal mixers 3, 4 where the sand is mixed with metered quantities of resin and catalyst respectively. The separate mixtures are delivered to a final mixer 7 where two mixing elements 8 rotate at high speed in the directions indicated by the arrows to impel the final mixture into a mould-box 9 containing a pattern 12. After filling the mould-box a plate 14 moves below the mixer 7. The completed mould is then compressed against the plate by a ram 10. The mould is stripped from the pattern 12 by pins 13.
