[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment of a self-lifting medical device forming mold, comprising a base 1, an open slot 3 is provided on the top of the base 1, a bidirectional screw rod 4 is rotatably connected to the right side of the base 1, the left end of the bidirectional screw rod 4 passes through the open slot 3 and is rotatably connected to the left side of the inside of the open slot 3, a clamping plate 5 is threadedly connected to the left and right sides of the outer wall of the bidirectional screw rod 4, an active bevel gear 6 is fixedly connected to the outside of the bidirectional screw rod 4, a fixed frame 10 is fixedly connected to the top of the base 1, a fixed disk 7 is fixedly connected to the right side of the inside of the fixed frame 10, a hollow rod 8 is rotatably connected to the middle part of the fixed disk 7, a driven bevel gear 9 is fixedly connected to the bottom end of the hollow rod 8, and the driven bevel gear 9 is meshed with the active bevel gear 6, and a hydraulic rod 20 is fixedly connected to the top of the inner side of the fixed frame 10 The output end of the hydraulic rod 20 is fixedly connected with a mounting plate 11, and an L-shaped plate 12 is fixedly connected to the top right side of the mounting plate 11. A rotating rod 13 is rotatably connected to the inside of the L-shaped plate 12 on the right side. The rotating rod 13 is slidably connected to the inside of the hollow rod 8. A threaded rod 14 is rotatably connected to the inside of the L-shaped plate 12 on the left side. A movable column 17 is threadedly connected to the outside of the threaded rod 14. The bottom end of the movable column 17 penetrates the mounting plate 11 and is fixedly connected to a pressing plate 18. A lifting mechanism 2 is provided at the middle of the top of the base 1. A transmission assembly is provided on the outside of the threaded rod 14. The transmission assembly includes a pulley 15 and a transmission belt 16. The two pulleys 15 are respectively fixedly connected to the rotating rod 13 and the upper and middle parts of the outer sides of the threaded rod 14. The two pulleys 15 are connected through a transmission belt 16.

[0031] Specifically, the bidirectional screw 4 can not only drive the clamping plate 5 on its outer side to move toward the middle, but also accurately limit and fix the lower mold 201, ensuring that the lower mold 201 always maintains a stable position during the processing. At the same time, when the bidirectional screw 4 rotates, the driving bevel gear 6 on its outer side will also rotate accordingly, and the driving bevel gear 6 meshes with the driven bevel gear 9, so that the driven bevel gear 9 can also rotate along with the rotation of the driving bevel gear 6. This precise meshing design ensures the stability and accuracy of the transmission process. The connection between the hollow rod 8 and the driving bevel gear 6 and the driven bevel gear 9 allows the hollow rod 8 to rotate accordingly. What is more clever is that a rotating rod 13 is provided inside the hollow rod 8, and the rotating rod 13 can also rotate simultaneously during the rotation of the hollow rod 8. The outer side of the rotating rod 13 is connected to the pulley 15, so when the rotating rod 13 rotates, the pulley 15 also rotates accordingly. The pulley 15 is connected to the pulley 15 on the outside of the threaded rod 14 through a transmission belt 16, so that the threaded rod 14 can also rotate with the rotation of the pulley 15. When the movable column 17 on the outside of the threaded rod 14 rotates, it can drive the pressing plate 18 to move downward to limit and fix the upper mold 19 in the mounting plate 11. This design makes the equipment easy and convenient to operate when replacing upper molds 19 and lower molds 201 of different sizes. In short, when it is necessary to disassemble and replace the upper mold 19 and the lower mold 201, it can be easily completed by simply reversing the above steps. This design makes the disassembly and replacement process simpler, greatly reducing the workload of the staff.

[0032] Reference Figure 1 , Figure 2 and Figure 4 The lifting mechanism 2 includes a lower mold 201 and a connecting rod 208. The lower mold 201 is arranged at the middle of the top of the base 1. The inner bottom of the lower mold 201 is fixedly connected to two support seats 202. The tops of the two support seats 202 are fixedly connected to the same servo motor 203. The output end of the servo motor 203 is fixedly connected to a movable shaft 204. The left end of the movable shaft 204 is fixedly connected to a disc 205. The left side of the disc 205 is fixedly connected to a fixed rod 206. The left end of the fixed rod 206 is rotatably connected to a first rotating shaft 207. The inner side of the lower mold 201 is slidably connected to a placing plate 209. The bottom of the placing plate 209 is rotatably connected to a second rotating shaft 210. The second rotating shaft 210 is connected to the first rotating shaft 207 through a connecting rod 208. The size of the placing plate 209 matches the internal size of the lower mold 201.

[0033] Specifically, when the servo motor 203 can drive the disk 205 to rotate, the first rotating shaft 207 on the disk 205 will rotate accordingly, which is a typical transmission method. In addition, the second rotating shaft 210 will also rotate through the connecting rod 208. This design enables the device to achieve more complex actions during operation and meet various processing requirements. The connecting rod 208 plays a role in connecting and transmitting force, so that the rotation of the second rotating shaft 210 can be smoothly transmitted to other components, improving the operation efficiency of the entire device. During the rotation of the disk 205, the fixed rod 206 will gradually move to the upper left side of the disk 205. This is because there is a certain gap between the fixed rod 206 and the disk 205 during the design, so that the fixed rod 206 can move smoothly under the drive of the disk 205. When the fixed rod 206 moves to the upper left side of the disk 205, the placement plate 209 will move upward from the lower mold 201 to eject the processed parts. This design makes the mold removal process simple and fast, greatly improving production efficiency.

[0034] Reference Figure 2 and Figure 3 The left and right sides of the movable column 17 are fixedly connected with a slider 21, and the top right front end of the mounting plate 11 is fixedly connected with a plurality of sliders 22, and the sliders 21 are respectively slidably connected to the outer sides of the corresponding sliders 22, and the two clamping plates 5 are slidably connected to the inside of the opening groove 3;

[0035] Specifically, the moving tracks of the moving column 17 and the clamping plate 5 can be limited by the sliding rod 22 and the opening slot 3, so that they can move more smoothly.

[0036] Reference Figure 1 A controller 24 is fixedly connected to the right side of the fixed frame 10, and the controller 24 is electrically connected to the hydraulic rod 20. A protective cover 25 is provided on the outer side of the controller 24, and one side of the protective cover 25 is rotatably connected to the right side of the fixed frame 10;

[0037] Specifically, the operation of the hydraulic rod 20 can be controlled by the controller 24, and the protective cover 25 can protect the controller 24 from being damaged by external factors.

[0038] Reference Figure 2 , the adjacent sides of the two clamping plates 5 are fixedly connected with rubber pads 23, and the interior of the mounting plate 11 is provided with an upper mold 19;

[0039] Specifically, the friction between the clamping plate 5 and the lower mold 201 can be further enhanced by the rubber pad 23, and the upper mold 19 can facilitate the normal processing of medical device parts.

[0040] Working principle: When using the device, first carry the device to the position where the medical device parts are to be processed through the handle on the fixed frame 10, and then place the lower mold 201 and the upper mold 19 on the base 1 and the mounting plate 11 in turn, and then rotate the bidirectional screw rod 4 to drive the outer clamping plate 5 to move toward the middle to limit and fix the lower mold 201. While the bidirectional screw rod 4 is rotating, the active bevel gear 6 on the outer side will be driven along, and the driven bevel gear 9 will also rotate along due to the engagement with the active bevel gear 6, the hollow rod 8 will rotate along, and the rotating rod 13 inside the hollow rod 8 will also rotate at the same time. At this time, the pulley 15 on the outer side of the rotating rod 13 will rotate along, and the pulley 15 on the outer side of the threaded rod 14 will rotate along through the transmission belt 16, thereby driving the threaded rod 14 to rotate. At this time, the movable column 17 on the outer side of the threaded rod 14 will drive the pressure plate 18 to move downward to limit and fix the upper mold 19 in the mounting plate 11. When it is necessary to disassemble and replace the upper mold 19 and the lower mold 201 of different sizes, just reverse the above steps. That is, it is relatively simple to disassemble and replace the upper mold 19 and the lower mold 201, which can reduce the workload of the staff and meet the needs of the users. After the upper mold 19 and the lower mold 201 are installed, first pour the part raw material into the placement plate 209 in the lower mold 201, and then the upper mold 19 can be driven by the hydraulic rod 20 to move downward to perform a molding operation on the raw material in the lower mold 201. While the mounting plate 11 moves downward, the rotating rod 13 will slide downward inside the hollow rod 8, which will not affect the fixing work of the upper mold 19 and the lower mold 201. After the processing work is completed, the servo motor 203 can drive the disc 205 to rotate, and the first rotating shaft 207 on the disc 205 will rotate accordingly, and the second rotating shaft 210 will also rotate through the connecting rod 208 until the fixing rod 206 moves to the upper left end of the disc 205. At this time, the placement plate 209 will move upward from the lower mold 201 to eject the processed parts. The mold removal is relatively simple, thereby improving the practicality of the device.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
