[0034] Further, the pouring outlet 5 is arranged below the outlet gate 2.

[0035] The pouring outlet 5 is in a closed state when the outlet gate 2 is pressed downwards, and is in an open state when the outlet gate 2 is lifted upwards, the pouring outlet 5 can reduce the flow area of the molten liquid, and prevent the molten liquid from spilling out of the mold.

[0036] Further, the heat preservation chute 1 is further provided with a limiting block 6 above the right side of the outlet.

[0037] The limiting block 6 is used for limiting the stroke of the outlet gate 2 when the outlet gate 2 is opened, so as to prevent the molten liquid from flowing out from below the outlet gate 2 due to excessive opening.
