Description

Technical Field

[0001] The invention relates to the field of ductile iron casting, in particular to a casting device for pearl-shaped "rain" graphite high-strength and high-toughness ductile iron. Background Art

[0002] The pearl-shaped "rain" graphite high-strength and high-toughness ductile iron described in the invention refers to ductile iron with pearl-shaped graphite, that is, the graphite in the ductile iron has a high roundness; generally, the spheroidization rate is ≥95% and the graphite diameter reaches level 7.

[0003] During the casting process of ductile iron, factors that affect the graphite morphology in the cast iron mainly include chemical composition, cooling conditions, alloying elements, and process control. In the prior art, during casting, the casting tube is generally hoisted by a crane in the production workshop, and then manually rotated by workers to achieve the pouring of molten iron. As a result, the casting process is labor-intensive and risky for workers. Furthermore, the position of the casting nozzle changes during the rotation of the casting tube, making it impossible to control the casting path. Consequently, it is difficult to control the flow rate of the molten iron, making it difficult to ensure the cooling rate of the molten iron during the casting process. This affects the graphite morphology in the ductile iron, and the quality of the casting cannot be guaranteed. Furthermore, the operation is difficult for workers, making it difficult to control the casting speed. Summary of the Invention

[0074] During operation, the cooling water within the cooling box 400 is pumped into the water-cooling box 600 by the second water-supply pump 430, cooling the mold 700. Because each water-cooling box 600 is equipped with a separate second water-supply device, each water-cooling box 600 can be cooled independently, reducing interference between cooling systems. The cooling water within the water-cooling box 600, after cooling the mold 700, is discharged through the outlet pipe 620 and then transported through the outlet main pipe 630 to the heat dissipation pipe 330.

[0075] The casting channel adjustment device 500 is used to adjust the casting channel 520 to be located between the casting nozzle of the casting cylinder 160 and the casting liquid inlet of the mold 700. Specifically, the casting channel adjustment device 500 can be provided with manual lifting devices at both ends of the casting channel 520; the casting channel 520 can then be manually moved and the casting angle of the casting channel 520 can be adjusted.

[0078] Specifically, the driving screw rod 540 is supported by providing vertical support plates, and the screw rod driving motor 550 is installed on one of the vertical support plates.

[0079] During operation, the screw drive motor 550 is activated to rotate the drive screw 540, thereby driving the first slider 510 to move and adjust the position of the casting channel 520. After the casting channel 520 is moved below the casting nozzle of the casting cylinder 160 and between the casting inlet of the mold, since one end of the casting channel 520 is hinged to the first slider 510 and the other end is hinged to the telescopic device 530, the angle of the casting channel 520 can be adjusted by activating the telescopic device 530 to extend and retract.

[0080] The main function of the crossbeam 800 is to support the mold lifting device 900. Specifically, a supporting column is provided below the crossbeam 800, and the crossbeam is supported by the supporting column.

[0081] The mold lifting device 900 is used to lift the mold 700, placing the mold 700 into the cooling chamber, or lifting the mold 700 out of the cooling chamber. Specifically, the mold lifting device 900 can be configured by providing a movable support arm on the crossbeam 800, and a movable pulley assembly on the support arm to achieve lifting. The pulley assembly can be a pulley assembly on a crane as is conventionally used.

[0082] In this embodiment, the mold lifting device 900 includes a second slider 910 provided on the crossbeam 800; a slot 911 matching the crossbeam 800 is provided at the lower end of the second slider 910; the second slider 910 is slidably mounted on the crossbeam 800;

[0086] During operation, the second driving device 920 is started to drive the second slider 910 to move, thereby driving the second horizontal telescopic device 930 to move, and the position of the lifting device is adjusted by controlling the extension and retraction of the second horizontal telescopic device 930.

[0087] When the lifting position is above the mold 700, pull out the pin 952, and by retracting the lifting plate 951, make the lifting plate 951 be located on the side of the lifting ear of the mold 700, and then insert the pin 952 so that one end of the pin 952 is inserted into the lifting ear and the other end is fixedly connected to the lifting plate 951.

[0088] Activating the second vertical telescopic device 941 causes the top plate 942 to move upward, thereby pulling the pull rod 943 upward, which in turn drives the lifting block 950 upward, thereby driving the mold 700 upward. After the mold 700 is released from contact with the water-cooling box 600, the second drive device 920 is activated to move the second slide 910, moving the mold 700 to the set position.

[0089] By adopting the mold lifting device 900 described above in this embodiment, the stability of the mold during lifting can be improved and the operation can be facilitated.

[0090] The mold 700 primarily functions to cast ductile iron. A conventional mold can be used; all that is required is that the mold's dimensions meet the requirements and that a structure is provided on the mold to allow it to be installed within the water-cooling box 600.

Finally, the outwardly extending ridge 720 provided on the upper surface of the mold body 710 defines the position of the mold 700, preventing the mold 700 from falling into the water-cooled box 600. Heat dissipation holes 740 provided on the ribs 730 facilitate the flow of cooling water and dissipate heat, improving heat dissipation.

[0093] The main function of the casting tube overturning device 100 is to realize the rotation of the casting tube 160, thereby realizing the dumping of the molten iron in the casting tube 160.

[0098] The moving device 180 can use universal wheels with brakes to achieve movement and braking; it can also achieve movement by setting guide rails.

[0099] During operation, the casting cylinder 160 is installed within the arc-shaped slider 120 so that the apex of the casting nozzle of the casting cylinder 160 is located at the center of the arc-shaped slider 120. When casting is required, the drive device 170 is activated, causing the drive device 170 to rotate the drive gear 172 via the transmission device 171. Since the drive gear 172 engages with the arc-shaped rack 124 on the back of the arc-shaped slider 120, it drives the arc-shaped slider 120 to rotate, and thus drives the casting cylinder 160 within the arc-shaped slider 120 to rotate. Since the apex of the casting nozzle of the casting cylinder 160 is located at the center of the arc-shaped slider 120, the casting cylinder 160 rotates around its apex, thereby ensuring that the casting position remains unchanged.

[0100] In this embodiment, all telescopic devices, whether horizontal, transverse or vertical, use hydraulic cylinders or pneumatic cylinders; the appropriate model is selected according to the location of the telescopic device; the specific model is selected according to the standards specified by the staff themselves.
