Molten metal multi-stage skimming and storing device for casting production

The utility model relates to a metal liquid multistage skimming and storing device for casting production, which comprises a main core body, a liquid inlet hole is arranged at the top of the main core body, a liquid outlet hole is arranged at the bottom of the main core body, and a storage device for skimming and storing slag is arranged in the main core body. According to the metal liquid multi-stage skimming and slag storage device for casting production, through the arrangement of the storage device, when high-temperature metal liquid enters the main core body and enters the inner core from the liquid inlet groove, the inner core can stop slag, the flowing metal liquid is fully filled and injected, the slag floats on the surface of the metal liquid, the metal liquid enters the inner core under the action of gravity, and the metal liquid is separated from the inner core. Under the action of gravity, the molten metal is jetted into the slag storage tank from bottom to top and finally discharged through the l
