[0028] The pouring module 200 includes two plug-in plates 210 plugged into the protective box 110, a slider 220 slidably connected to the plug-in plates 210, an L-shaped plate 230 installed on the inner side of the slider 220, an iron bucket 240 movably connected between the two L-shaped plates 230, two cylinders 250 connected to the top of the iron bucket 240, a sealing plate 260 connected between the two cylinders 250, a rotating rod 270 connected to the iron bucket 240, and a switch 280 connected to the rotating rod 270. The two cylinders 250 are connected in series, and the switch 280 is electrically connected to one cylinder 250.

[0029] Furthermore, the two threaded rods 130 are symmetrical about the vertical center plane of the protective box 110 , and the threaded rods 130 are arranged in a T shape. This layout design provides conditions for compacting multiple mold shells 150 .

[0030] Furthermore, the sealing plate 260 is located between the two cylinders 250, and the sealing plate 260 is movably connected to the top of the molten iron bucket 240. With this structural design, the sealing plate 260 is in an open state when the molten iron bucket 240 is discharging water, and is in a closed state when the molten iron bucket 240 is lifted, which effectively prevents molten iron from splashing.

[0031] Furthermore, the rotating rod 270 is configured to be T-shaped, and the bottom end of the rotating rod 270 is interference fit with the top of the L-shaped plate 230 . This shape design makes it convenient for the user to rotate the molten iron bucket 240 . Example 2

[0032] Combination Figure 1-2 As shown, based on the first embodiment, the pressing plate 140 is configured as an isosceles trapezoid, and the bottom thereof is in contact with the bottom of the inner cavity of the protective box 110. With this structural design, when the threaded rod 130 rotates, the pressing plate 140 can move in translation. Example 3

[0033] Combination Figure 1 and Figure 3 As shown, in the above embodiment, a plurality of reinforcing plates 300 are connected between the slider 220 and the L-shaped plate 230. The plurality of reinforcing plates 300 are arranged in a row at equal intervals. The provision of the reinforcing plates 300 can improve the connection strength between the slider 220 and the L-shaped plate 230.

[0034] The working principle and use process of the utility model are as follows: when the device is put into actual use, the mold shells 150 are placed in pairs in the protective box 110, and then the threaded rod 130 is rotated, and then the pressing plate 140 is translated along the bottom of the inner cavity of the protective box 110. This process continues until multiple mold shells 150 are pressed tightly, and then the rotating rod 270 is rotated to align the water outlet end of the molten iron bucket 240 with the mold shell 150, and then the switch 280 is pressed, the movable ends of the two cylinders 250 are extended, and then the sealing plate 260 opens the top of the molten iron bucket 240, and the molten iron is accurately poured into the mold shell 150. After that, when the molten iron bucket 240 is moved to the top of another mold shell 150, the staff presses the switch 280 to shrink the movable end of the cylinder 250, and then the sealing plate 260 blocks the top of the molten iron bucket 240, which effectively prevents the molten iron from falling onto the outer surface of the mold shell 150, eliminates sparks and splashes, and improves the safety of the pouring operation.
