Title: Foundry sand mould for mfg. metal castings - where downstick is formed by sheet metal funnel closed by disks which melt when molten metal enters funnel
Inventor: STENDER-ROBERTZ JOST
IPC: B22D35/04
Filed: 1978-12-16
Abstract: The mould is filled with sand to form a cavity and also a downstick. The bottom end of the downstick is closed by a disc made of an appropriate material with a suitable thickness so the disc only melts after an appreciable amt. of molten metal has collected in the downstick. The pref. disc is made of metal plate and located between the cope and drag. The disc pref. forms the base of a funnel made of sheet metal and inserted in the downstick, where the top rim of the funnel is higher than the top surface of the cope and is covered by a lid. The funnel may contain more than one disc melted by the metal poured into the downstick. Molten metal flowing down the funnel and along a runner into the mould cavity does not erode sand from the wall of the downstick, so such sand is not carried into the casting.
