[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a split bottom-casting model for ductile iron and gray iron casting, comprising a workbench 1, an opening slot 3 on the top of the workbench 1, a first bidirectional lead screw 4 rotatably connected to the right side of the workbench 1, the left end of the first bidirectional lead screw 4 passing through the opening slot 3 and rotatably connected to the left side inside the opening slot 3, a first driving bevel gear 5 fixedly connected to the outer side of the first bidirectional lead screw 4, a fixed frame 16 fixedly connected to the top of the workbench 1, a disc 6 fixedly connected to the right side inside the fixed frame 16, a hollow rod 7 rotatably connected to the middle of the disc 6, a first driven bevel gear 8 fixedly connected to the bottom end of the hollow rod 7, the first driven bevel gear 8 meshing with the first driving bevel gear 5, a hollow frame 9 provided on the upper side of the workbench 1, and a second bidirectional lead screw 5 rotatably connected to the inside of the hollow frame 9. The right end of the first double-acting screw 10 passes through the hollow frame 9 and is fixedly connected to the second driven bevel gear 11. The right side of the hollow frame 9 is fixedly connected to the fixing plate 12. The bottom right side of the fixing plate 12 is rotatably connected to the rotating rod 13. The upper outer part of the rotating rod 13 is fixedly connected to the second driving bevel gear 14. The second driving bevel gear 14 is meshed with the second driven bevel gear 11. The rotating rod 13 is slidably connected to the interior of the hollow rod 7. The left and right sides of the outer walls of the first double-acting screw 4 and the second double-acting screw 10 are threaded with clamping plates 18. The top center of the worktable 1 is provided with a lifting mechanism 2. The upper mold 15 is provided on the adjacent side of the two clamping plates 18 on the upper side. The top inner side of the fixing frame 16 is fixedly connected to the hydraulic rod 17. The output end of the hydraulic rod 17 is fixedly connected to the top of the hollow frame 9.

[0031] Specifically, rotating the first bidirectional lead screw 4 drives the first driving bevel gear 5 to rotate. Since the first driven bevel gear 8 meshes with the first driving bevel gear 5, it also rotates with the rotation of the outer side of the hollow rod 7. At this time, the second driving bevel gear 14 on the outer side of the rotating rod 13 will rotate accordingly. Since the second driven bevel gear 11 meshes with the second driving bevel gear 14, it will also drive the second bidirectional lead screw 10 to rotate. When the first bidirectional lead screw 4 and the second bidirectional lead screw 10 rotate simultaneously, the clamping plate 18 will move to both sides. At this time, the upper mold 15 and the lower mold 201 are placed into the corresponding two clamping plates 18 respectively. Then, by reversing the above steps, the upper mold 15 and the lower mold 201 can be positioned simultaneously. This design simplifies the mold changing process, reduces the difficulty of operation for workers, and improves production efficiency.

[0032] Reference Figure 1 and Figure 3The lifting mechanism 2 includes a lower mold 201 and a connecting rod 206. The lower mold 201 is located at the top center of the workbench 1. A servo motor 202 is fixedly connected to the bottom inner side of the lower mold 201. A fixed plate 203 is fixedly connected to the output end of the servo motor 202. A fixed rod 204 is fixedly connected to the left side of the fixed plate 203. A first rotating shaft 205 is rotatably connected to the left end of the fixed rod 204. A placement plate 207 is slidably connected to the inner side of the lower mold 201. A second rotating shaft 208 is rotatably connected to the bottom of the placement plate 207. The second rotating shaft 208 is connected to the first rotating shaft 205 through the connecting rod 206. The size of the placement plate 207 matches the internal size of the lower mold 201.

[0033] Specifically, the servo motor 202 can drive the fixed disk 203 to rotate. When the fixed disk 203 starts to rotate, the first rotating shaft 205 mounted on it will rotate accordingly. At the same time, the second rotating shaft 208 is connected to the first rotating shaft 205 through the connecting rod 206. Therefore, when the first rotating shaft 205 rotates, the second rotating shaft 208 will also rotate. As the second rotating shaft 208 rotates, the placement plate 207 will be lifted, making it easy to remove the casting. This device design not only improves the efficiency of casting removal but also reduces the labor intensity of workers.

[0034] Reference Figure 3 Multiple clamping plates 18 are slidably connected to the corresponding opening slots 3 and the interior of the hollow frame 9, and a rubber pad 19 is fixedly connected to one side of each of the multiple clamping plates 18.

[0035] Specifically, the rubber pad 19 can further increase the friction between the clamping plate 18 and the upper mold 15 and the lower mold 201, making it more stable.

[0036] Reference Figure 1 A controller 20 is fixedly connected to the right side of the fixed frame 16. The controller 20 is electrically connected to the servo motor 202 and the hydraulic rod 17 respectively. A protective cover 21 is provided on the outside of the controller 20. One side of the protective cover 21 is rotatably connected to the right side of the fixed frame 16.

[0037] Specifically, the controller 20 can control the operation of the servo motor 202 and the hydraulic rod 17, while the protective cover 21 protects the controller 20 from damage caused by external factors.

[0038] Working principle: When processing castings of different sizes, firstly, rotating the first double-acting lead screw 4 drives the first driving bevel gear 5 to rotate. The first driven bevel gear 8 on the outer side of the hollow rod 7, meshing with the first driving bevel gear 5, will also rotate. At this time, the second driving bevel gear 14 on the outer side of the rotating rod 13 will rotate, and the second driven bevel gear 11 on the second double-acting lead screw 10, meshing with the second driving bevel gear 14, will also rotate. Simultaneously, the first double-acting lead screw 4 and the second double-acting lead screw 10 will rotate, allowing the clamping plates 18 to move to both sides. Then, the upper mold 15 and the lower mold 201 are placed into their respective clamping plates 18. Reversing the above steps allows for simultaneous positioning of the upper mold 15 and the lower mold 201. Disassembly and replacement of different sizes are then possible. The upper mold 15 and lower mold 201 are relatively simple in size, which reduces the workload of the workers and meets the needs of the users. The upper mold 15 can be moved downward by the hydraulic rod 17 to mold the raw material injected into the lower mold 201. At this time, the rotating rod 13 will enter the hollow rod 7 at the same time, which can always keep the upper mold 15 and lower mold 201 in a fixed position. After the processing is completed, the servo motor 202 can drive the fixed plate 203 to rotate. The first rotating shaft 205 on the fixed plate 203 will rotate accordingly, and the second rotating shaft 208 will rotate along with it through the connecting rod 206. At this time, the placement plate 207 will be lifted, which makes it convenient for the workers to take out the processed castings, thereby improving the practicality of the device.

[0039] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
