After waiting for a certain time, the material gradually forms the shape of the inner wall of the mold, so as to achieve the purpose of ductile iron casting production.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0021] To solve the technical problem of low demolding and blanking efficiency of ductile iron castings, as Figures 1-4 shown, the following preferred technical solutions are provided:
[0022] A ductile iron casting production demolding device includes a base 1. Above the base 1, there is a placement table 3. Inside the bottom end of the placement table 3, there is a mold 5. At the bottom of the mold 5, there is a top plate 6. The top plate 6 can perform reciprocating linear motion in the vertical direction. Outside the mold 5, there are several clamping plates 8. The clamping plates 8 can perform reciprocating linear motion in the horizontal direction. Inside the placement table 3, there is a push plate 15. The push plate 15 can perform reciprocating linear motion in the horizontal direction. Above the mold 5, there are two symmetrically arranged limiting plates 24. The limiting plates 24 can perform reciprocating linear motion in the vertical direction. Above the limiting plates 24, there is a corresponding moving plate 22. The moving plate 22 can drive the two limiting plates 24 to perform synchronous approaching or separating motion in the horizontal direction.
[0023] Specifically, first place the mold 5 inside the placement table 3. Subsequently, the clamping plate 8 moves towards the mold 5 to fix the mold 5 inside the placement table 3. Then, pour the material required for the ductile iron casting into the inner wall of the mold 5, enabling the material to gradually take shape and form the shape of the inner wall of the mold 5, thereby achieving the purpose of processing the ductile iron casting. When the ductile iron casting is completed, the two moving plates 22 drive the corresponding limit plates 24 to move synchronously towards each other horizontally, aligning the limit plates 24 with the edge of the mold 5. Then, the limit plates 24 move downward to apply pressure to the mold 5, providing vertical direction limitation to the mold 5. The top plate 6 starts to move upward, ejecting the ductile iron casting from inside the mold 5 to be on the same horizontal plane as the placement table 3. Subsequently, the limit plates 24 move upward to prevent blocking the movement of the push plate 15. Finally, the push plate 15 moves in a reciprocating linear motion vertically to push the ductile iron casting to the collection end for collection. The purpose of this design is to place the mold 5 inside the placement table 3, then the clamping plate 8 moves towards the mold 5 to fix the mold 5 inside the placement table 3, and then pour the material required for the ductile iron casting into the inner wall of the mold 5, enabling the material to gradually take shape and form the shape of the inner wall of the mold 5, thereby achieving the purpose of processing the ductile iron casting. When the ductile iron casting is completed, the two moving plates 22 drive the corresponding limit plates 24 to move synchronously towards each other horizontally, aligning the limit plates 24 with the edge of the mold 5. Then, the limit plates 24 move downward to apply pressure to the mold 5, providing vertical direction limitation to the mold 5. The top plate 6 starts to move upward, ejecting the ductile iron casting from inside the mold 5 to be on the same horizontal plane as the placement table 3. Subsequently, the limit plates 24 move upward to prevent blocking the movement of the push plate 15. Finally, the push plate 15 moves in a reciprocating linear motion vertically to push the ductile iron casting to the collection end for collection. It is no longer necessary for workers to take out the ejected ductile iron casting outward, improving the efficiency of mold removal and blanking.

The purpose of this design is that the support columns 2 can fix the placement table 3 above the base 1, and the output end of the first hydraulic rod 7 extends upward to drive the top plate 6 to move upward to eject the ductile iron casting inside the mold 5, making it on the same horizontal plane as the inner bottom surface of the placement table 3 for easy collection.
[0026] Furthermore, as Figure 1 andFigure 3 As shown, the following preferred technical solutions are provided:
[0027] A number of uniformly distributed rectangular blocks 11 are fixedly connected to the bottom end surface of the placement table 3. A second hydraulic rod 10 is fixedly installed on one side of the rectangular block 11. The output end of the second hydraulic rod 10 enters the inside of the rectangular groove 4 and is fixedly connected to the middle of the side surface of the clamping plate 8. The purpose of this design is to drive the clamping plate 8 to perform a reciprocating linear motion in the horizontal direction through the expansion and contraction of the second hydraulic rod 10.
[0028] Further, as Figure 1 and Figure 2 As shown, the following preferred technical solutions are provided:
[0029] Two symmetrically arranged first chutes 12 are opened at the upper end of the inner side surface of the placement table 3. A first slider 13 is arranged inside the first chute 12. The first slider 13 is slidably connected to the inner wall of the first chute 12. The first slider 13 is fixedly connected to a push plate 15. A lead screw 14 is arranged inside the first chute 12 on the right side of the placement table 3. The lead screw 14 is threadedly connected to the first slider 13. The two ends of the lead screw 14 are rotatably connected to the inner walls at both ends of the first chute 12 through bearings. A first motor 16 is fixedly installed outside the placement table 3. One end of the lead screw 14 extends outward and is fixedly connected to the output end of the first motor 16. The purpose of this design is to drive the rotation of the lead screw 14 through the rotation of the output end of the first motor 16. The rotation of the lead screw 14 drives the threadedly connected first slider 13 to perform a reciprocating linear motion in the horizontal direction. The first slider 13 drives the push plate 15 to perform a reciprocating linear motion in the horizontal direction, and pushes the ductile iron castings ejected from the mold 5 to the collection end for collection.
[0030] Further, as Figure 1 and Figure 4 As shown, the following preferred technical solutions are provided:
[0031] The upper end surface of the placement table 3 is fixedly connected with a rectangular frame 17. Two symmetric second sliding grooves 18 are provided on the inner side surface of the upper end of the rectangular frame 17. Two symmetric second sliding blocks 19 are arranged inside the second sliding grooves 18. The second sliding blocks 19 are slidably connected to the inner wall of the second sliding grooves 18.

The middle part of the lower end of the moving plate 22 is fixedly installed with an electric telescopic rod 23. The output end of the electric telescopic rod 23 is fixedly connected to the middle part of the upper end of the limiting plate 24. The purpose of this design is that the rotation of the output end of the second motor 21 drives the rotation of the bidirectional threaded screw rod 20. The rotation of the bidirectional threaded screw rod 20 drives the two moving plates 22 to move synchronously in opposite or away directions horizontally. The moving plates 22 drive the limiting plates 24 to move synchronously in opposite or away directions horizontally, so that the two limiting plates 24 just move to both side edges at the upper end of the mold 5. Then the output end of the electric telescopic rod 23 extends downward, driving the limiting plate 24 to move downward in the vertical direction, squeezing the upper end of the mold 5, so that the movement of the mold 5 in the vertical direction is limited by the limiting plate 24, preventing the mold 5 from moving in the vertical direction when the top plate 6 ejects the ductile iron casting.
[0032] Further, as Figure 1 and Figure 2 shown, the following preferred technical solutions are provided:
[0033] A rubber layer 9 is attached to the side surface of the clamping plate 8. The purpose of this design is that through the rubber layer 9, the clamping plate 8 can be more closely attached to the side surface of the mold 5.

[0035] One end of the placement table 3 is provided with an outlet 25. The outlet 25 is fixedly connected with a slope 26. The purpose of this design is that through the slope 26, the ductile iron casting coming out of the outlet 25 can be slowly slid into the collection box placed below the slope 26 by gravity, facilitating the collection of the ductile iron casting.
[0036] In summary: During use, first place the mold 5 inside the placement table 3. Subsequently, the clamping plate 8 moves towards the mold 5 to fix the mold 5 inside the placement table 3. Then, pour the material required for the ductile iron casting into the inner wall of the mold 5, enabling the material to gradually take shape and form the shape of the inner wall of the mold 5, thereby achieving the purpose of processing the ductile iron casting. When the ductile iron casting is completed, the two moving plates 22 drive the corresponding limiting plates 24 to move synchronously towards each other horizontally, aligning the limiting plates 24 with the edge of the mold 5. Then, the limiting plates 24 move downward to apply pressure to the mold 5 for vertical direction limiting. The top plate 6 starts to move upward to eject the ductile iron casting from the mold 5 to the same horizontal plane as the placement table 3. Subsequently, the limiting plates 24 move upward to prevent blocking the movement of the push plate 15. Finally, the push plate 15 moves in a reciprocating straight line vertically to push the ductile iron casting to the collection end for collection. The purpose of this design is to place the mold 5 inside the placement table 3, then the clamping plate 8 moves towards the mold 5 to fix the mold 5 inside the placement table 3, and then pour the material required for the ductile iron casting into the inner wall of the mold 5, enabling the material to gradually take shape and form the shape of the inner wall of the mold 5, thereby achieving the purpose of processing the ductile iron casting.
