The middle arc plate (94) separates from the sliding hole plate (91), causing the round hole on the sliding hole plate (91) to separate from the round hole on the arc plate (72), thus stopping the injection of molten iron.

3. The iron weighing device for iron pot production according to claim 2, characterized in that: It also includes a pushing mechanism (10), which includes a fixed frame (101), a long cylinder (102), a connecting rod frame (103), a large arc plate (104), a top rod (105), a rotating corner plate (106), and a torsion spring (107). The lower left and right sides of the upright frame (2) are connected to the fixed frame (101), and the upper part of the fixed frame (101) is connected to the long cylinder (102). The telescopic rod of the long cylinder (102) is connected to the connecting rod frame (103). The upper front side of the two connecting rod frames (103) is connected to the large arc plate (104). The lower right side of the left connecting rod frame (103) is connected to the top rod (105). The lower inside of the thick connecting plate (53) is connected to the rotating corner plate (106). 6) The upper part is an S-shaped block and the lower part is a top arc-shaped protrusion. A torsion spring (107) is connected between the lower part of the rotating corner plate (106) and the upper part of the lower part of the thick connecting plate (53). The torsion spring (107) is wrapped around the lower part of the rotating corner plate (106). When the long cylinder (102) is activated, the telescopic rod of the long cylinder (102) drives the connecting rod frame (103) and the push rod (105) to move backward. The push rod (105) contacts the protrusion under the rotating corner plate (106), so that the rotating corner plate (106) rotates clockwise. The torsion spring (107) is compressed. The S-shaped block on the upper part of the rotating corner plate (106) pushes the connecting round corner plate frame (61) and the small arc plate (64) outward. The small arc plate (64) separates from the mold (4), thereby removing the mold (4).
