[0040] Reference Figure 2 , Figure 3 A motor 21 is fixedly connected to the top of the top plate 3. The drive end of the motor 21 is fixedly connected to a rotating shaft 22 through the top plate 3. A gear 23 is fixedly connected to the outside of the rotating shaft 22 to drive a gear 25 to rotate. A rotating shaft 24 is rotatably connected inside the connecting plate 6. A gear 25 is fixedly connected to the outside of the rotating shaft 24. A receiving plate 26 is fixedly connected to one end of the rotating shaft 24 to adjust the position of the blocking block 29 and the connecting pipe 27. A blocking block 29 is fixedly connected to the bottom of the receiving plate 26. A connecting pipe 27 is fixedly connected to the bottom of the receiving plate 26. A refractory pipe 28 is fixedly connected to the top of the receiving plate 26. The gear 25 is externally meshed with the outside of the gear 23. The blocking block 29 and the connecting pipe 27 are externally slidably connected to the inner wall of the pouring port 15 for conveying molten metal.

[0041] The molten metal is poured into the pouring port 15 and enters the mold shell 8 and mold shell 11. The molten metal is then cooled to a solid state and takes the desired shape. At this point, the metal casting is complete. The mold rod 20 is removed from the mold shell 8 and mold shell 11. The mold shell 8 is raised and the mold shell 11 is rotated so that the metal casting falls into the external storage box.

[0042] Working principle: In the initial state, the connecting plate 6 is at a high position, close to the top plate 3, and the connecting pipe 27 is close to the damper 7. Rotating the rotating rod 10 causes the mold shell 11 to rotate, so that the top of the mold shell 11 and the mold shell 14 are parallel. Holding the handle 18, insert the mold rod 20 connected to the receiving block 19 into the mold shell 14. Start the cylinder 4 to drive the telescopic rod 5 to extend and retract, which drives the connecting plate 6 to move. The connecting plate 6 drives the damper 7 to move, which in turn drives the mold shell 8 to move, so that the mold shell 8 is above the mold shell 11. Continue to extend and retract the telescopic rod 5, which drives the connecting plate 6 to move, squeezing the damper 7 and applying a downward force to the mold shell 8, so that the mold shell 8 is close to the mold shell 11.

[0043] Insert the insert rod 16 into the inserted block 17 until the connecting pipe 27 is inserted into the pouring port 15. The molten metal is then fed into the mold shell 1 8 and mold shell 2 11 through the refractory pipe 28. The cylinder 4 is activated to repeat the above process in reverse, causing the telescopic rod 5 to extend and retract, raising the connecting plate 6 a certain distance. The rotating shaft 24, connected to the inside of the connecting plate 6, moves along with the connecting plate 6, allowing the damper 7 to return to its original length. The rise of the connecting plate 6 stops, and the connecting pipe 27 is pulled out of the pouring port 15, rising a certain distance. At this time, gear 1 23 and gear 24... When the second wheel 25 engages, the motor 21 drives the rotating shaft 22 to rotate. Through the gear 23, the second gear 25 rotates, which in turn drives the rotating shaft 24 to rotate, thereby driving the receiving plate 26 to rotate. The positions of the blocking block 29 and the connecting pipe 27 are adjusted. The cylinder 4 is started to drive the telescopic rod 5 to extend and retract, causing the connecting plate 6 to descend and re-press the damper 7. At the same time, the blocking block 29 is inserted into the pouring port 15 to ensure that no external impurities enter the mold shell 8 and mold shell 11 through the pouring port 15 when the molten metal in the mold shell 8 and mold shell 11 is cooled.

[0044] The heat from the liquid metal is transferred to the mold shell 11 via the heat-conducting plate 30. The water pump 33 draws coolant from the ring pipe 31 through pipe 32 and transports it to the water tank 35 through pipe 34. As the coolant passes through pipes 32 and 34, the heat carried by the coolant is dissipated into the air. The coolant in the water tank 35, having released heat, is then transported back to the ring pipe 31 by gravity through pipe 36, forming a coolant circulation. This continuously absorbs heat from the liquid metal, accelerating its cooling until it solidifies, thus increasing work efficiency.

[0045] After the metal inside mold shell 1 8 and mold shell 2 11 cools down, a cooling device for preparing automotive balance shaft bracket castings is formed. Hold the handle 18 and pull it in the opposite direction to mold shell 3 14 to pull out mold rod 4 20. Start cylinder 4 and operate in the reverse of the above process to move connecting plate 6 to the initial position. Hold slider 13 and move it in the direction of damper 2 to squeeze the damper. Rotate rotating rod 10 to drive mold shell 2 11 to rotate, so that the cooled automotive balance shaft bracket casting preparation cooling device is separated from mold shell 2 11.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
