Abstract

1,256,191. Moulding machines; flasks. HEINRICH WAGNER G.m.b.H., [trading as HEINRICH WAGNER MASCHINENFABRIK]. 10 July, 1970 [11 July, 1969], No. 33682/70. Heading B3F. [Also in Division B8] A stack moulding machine includes mouldbox supports 8-17 (each carrying a pattern plate 20) interconnected to form an endless conveyer and two star-wheels 6 which engage rollers 18 on the mould-box supports to successively present the supports to a mould-box loading station, sand-charging station, pressing station and mould-box unloading station. A stack of empty mould-boxes 42 on a truck 39 is brought below a mould-box support 9 and raised so that the support 9 clamps the uppermost mould-box. The conveyer is rotated so that the clamped mould-box enters the position 12 where sand from a hopper 24 is sieved (25) upon the pattern to form a fine facing layer. As the mould-box progresses beneath the hopper mouth 27 it is filled with sand. A scraper 28 removes surplus sand. A final fine-sand layer is provided by a sieve 26. The moulding sand is compacted by a presser 33 at a position 14. When the filled mould box arrives at a position 17, it is lowered on to a stack of completed moulds 41 on a truck 40 so that all the downsprues in the moulds are aligned. In an alternative embodiment, only one pattern plate is provided, this being attached to the presser head to impress a mould cavity into sand. Flasks.-In Fig. 4, the flask (mould-box) made of a flat iron bar 43 welded at two opposing sides to iron angle 44 is shown clamped to a mould-box support 8 by sprung levers 51. The flask is released from its support by operation of pistons and cylinders 53, 54 to overcome the compression of the springs 50.
