Abstract

1,142,378. Moulding machines. MOSKOVSKY AVTOMEKHANICHESKY INSTITUT. 13 Oct., 1966, No. 45785/66. Heading B3F. In a method of manufacturing moulds by pressing sand between a movable pattern board 2 carrying a pattern 1 and a die plate 6, held stationary, a cavity is provided in the die plate of a particular depth to allow a particular density of the compressed sand to be achieved at the mould surface after pressing. A piston 4 carrying the pattern board 2 is initially set below the bottom face of a flask 5 within a guide frame 3, sand is poured into the flask to fill to the level of the top of the flask 5 and the die plate 6 is placed on top. Piston 4 is then raised to compress the sand. The Specification includes formulae for calculating the distance A 0 the pattern board is set below the bottom of the flask and the depths Y 1 and Y 2 of the cavity in the die plate 6, said formulae employing a squeezing coefficient K which characterises the degree of compression of the moulding sand.
