Abstract

A system for making foundry molds comprises the combination of a plurality of mold flasks (11) mounted on indexing means (12) for indexing the flasks (11) through a succession of different stations (A1-A3,B1-B3), and a mold-­ forming station (A1 ,B1) associated with the indexing means (12) for pre-filling one of said mold flasks (11) with sand, squeezing the sand within the flask (11) to form a mold with a pattern engaging at least one side thereof, and then drawing the pattern away from the mold. The forming station (A1,B1) includes a sand magazine (20) mounted for movement between a sand loader (10) and the forming station (A1,B1) so that said magazine (20) can be loaded with sand while a mold is being formed, pre-filling means (50,51,52,53,54,55) for supplying pressurised air to the top of the magazine (20) the forming station (A1,B1) to quickly discharge sand from the magazine (20) into a mold flask (11) positioned at the forming station (A1,B1), and a squeeze head (22) for forming the top surface of the mold during the squeezing operation at the forming station (A1,B1), said squeeze head (22) being movable in and out of the forming station (A1,B1) to permit the sand magazine (20) to enter said station (A1,B1). A mold discharge station (A3,B3) associated with said indexing means (12) received flasks (11) containing formed molds and removed the molds from the flasks (11) onto a mold platform (14a,14b) or a mold stack 13a, 13b) on the platform (14a,14b).
