International Classification:
B22D 1720, B22D 1730
US Classification:
164312
Abstract:
The die casting machine includes a trough containing a supply of molten metal and a feed tube extending into the supply of molten metal in the trough. A flow of molten metal is maintained in the trough past the feed tube independent of the transfer of molten metal through the feed tube. The die casting machine further includes a filtering system.

Compliant Fill Tube Assembly, Fill Tube Therefor And Method Of Use
US Patent:
7407068, Aug 5, 2008
Filed:
Jan 21, 2004
Appl. No.:
10/761582

International Classification:
B22D 41/14
US Classification:
222607, 222606, 164335
Abstract:
A fill tube assembly is for a casting mold. The fill tube assembly includes a fill tube having a tubular member with a receiving end, a mold-engaging end and an intermediate portion. The mold-engaging end has a tapered flange radially extending therefrom, the remainder of the tubular-member has a substantially uniform cross-section. A clamping assembly is structured to maintain a substantially leak-proof seal at the fill tube, casting mold interface while accommodating dimensional variations. The clamping assembly includes a gasket, a load ring, a clamping plate and a pre-load gap between the clamping plate and the casting mold and optionally includes a dimensional compensating ring. When tightened, the clamping plate biases the load ring against the flange thereby distributing a uniform load against the casting mold, compressing the gasket therebetween while narrowing the pre-load gap to accommodate dimensional variations. A method of use is also disclosed.
