The method, state of supply pressure and supply system for feeding pressure post casting

摘要

Invention patent: b "method, state of supply pressure and supply system for feeding pressure post cast" d .When leaking in casting cavities (not shown) in casting moulds (6) having supply reservoirs later (8), spears tubular (1) are introduced.First with its tip at a short distance from the feed tank later (8),After that the spears (1) are pressurized from a pressure chamber (3) and by means of a member (5) with an inclined surface by pressing down the last and short distance up the REservatu00f3rio feeding later (8) so as to pressurize it.With this arrangement, it is possible to pressurize the rear supply reservoirs (8) without the need of equipping the casting moulds (6) with complicated and additional equipment and without the risk ofThe molten metal is pressurized unnecessarily.
