Beginning opposite direction overturning is poured after pouring into molten metal in 17, and molten metal passes through difference by bottommost first in the process
The cast gate of position steadily enters type chamber, can guarantee that turbulent flow seldom occurs for molten metal in this way；With the continuous variation of flip angle
Gas in type chamber is gradually discharged；Oxide slag inclusion on liquid level is suspended in molten metal surface, rises to riser finally to last
It excludes.
This anti-overturning pouring type meets the distinctive bottom pouring type pouring requirement of aluminium alloy, in this way can be to avoid normal overturning
Mode generate molten metal swash splash, turbulent flow, oxide slag inclusion and gas hole defect.
Prevent spilling when molten metal excess casting from safety problem occurs to make instead to overturn casting, above-mentioned reversion is poured hopper
17 are also devised with overflow baffle 21.
The present invention is counter to overturn that casting process is steady, may ultimately reach the oxide slag inclusion of casting and the casting that stomata, cold shut are few
Part produces quality of aluminum alloy casting parts with this mode and stablizes, and high yield rate obtains good casting.
