Abstract

1371988 Foundry moulding machines GLYNWED FOUNDRIES Ltd 2 Feb 1973 [14 Feb 1972] 6710/72 Heading B3F A foundry mould for centrifugal pipe casting is made by placing a hollow cylindrical flask 1 on a movable cradle 9 between a sand blow-head 20 and a plate 21. The flask 1 is located and clamped therebetween by guide sleeves 14, 26. A mandrel 30 with an oversized head 34 is passed through the flask 1 from a first socketforming pattern 28 mounted on the plate 21 to abut a second socket-forming pattern 16. Sand is blown into the space between the flask 1 and mandrel 30. The ends of the so-formed pipemould are compressed by movement of the second socket-forming pattern 16 and a compression ring 29 into the flask 1 towards one another. After end compression of the mould the mandrel 30 is withdrawn towards (and eventually beyond) the plate 21 thereby compacting the formed mould along its whole length by means of the oversized head 34.
