DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-4, the utility model provides a technical solution: a mold for manufacturing an anatomical intervertebral fusion device facilitating discharging, comprising: a fixed mold 1, a telescopic rod 2, a movable mold 3, a bottom plate 4, a telescopic groove 5, an adjusting rod 6, an air nozzle 7, a blowing device 8, a pop-up plate 9, a first spring 10, a side groove 11, a first limiting plate 12, a second spring 13, a support rod 14, a pressing block 15, a top plate 16, a feeding device 17, a connecting pipe 18, a second limiting plate 19, an inner mold 20, a buckle 21 and a connection port 22.

[0031] Among them, the movable mold 3 is connected above the fixed mold 1 through the telescopic rod 2. The movable mold 3 forms a lifting structure above the fixed mold 1. The bottom plate 4 is horizontally arranged inside the fixed mold 1, and an adjusting mechanism for height adjustment is arranged at the bottom of the bottom plate 4. And a pop-up mechanism is arranged on the side of the bottom plate 4. The air nozzle 7 is fixedly installed at the center position of the bottom plate 4, and the end of the air nozzle 7 is communicated with a blowing device 8 located at the bottom of the fixed mold 1. The side grooves 11 are symmetrically opened on the inner side wall of the fixed mold 1, and a bottom limiting mechanism is arranged inside the side grooves 11. The top plate 16 is horizontally arranged inside the movable mold 3, and a connecting pipe 18 is installed at the center of the top plate 16. And the top end of the connecting pipe 18 is connected with a feeding device 17. The inner mold 20 is arranged inside the fixed mold 1, and buckles 21 corresponding to the side grooves 11 are arranged on the side of the inner mold 20. And a connection port 22 communicated with the air nozzle 7 is arranged at the bottom of the inner mold 20. The connection port 22 corresponds to the air nozzle 7, and the air nozzle 7 can be blown through the blowing device 8, so that the intervertebral fusion device inside the inner mold 20 is separated from the inner mold 20, and at the same time, the intervertebral fusion device is blown out to facilitate discharging.

[0032] Further, the adjusting mechanism includes a telescopic groove 5 and an adjusting rod 6. The telescopic grooves 5 are symmetrically opened on the bottom surface of the fixed mold 1, and the adjusting rods 6 are correspondingly threadedly connected to the tops of the telescopic grooves 5. And the tops of the adjusting rods 6 are rotatably connected to the inside of the bottom plate 4, which is convenient for driving the bottom plate 4 to lift by rotating the adjusting rods 6 above the telescopic grooves 5, so as to install and use inner molds 20 with different heights.

[0033] Further, the ejection mechanism includes an ejection plate 9 and a first spring 10. The ejection plate 9 is symmetrically arranged on the side of the bottom plate 4, and the bottom of the ejection plate 9 is elastically telescopically connected to the bottom plate 4 through the first spring 10. The bottom limit mechanism includes a first limit plate 12 and a support rod 14. The first limit plate 12 is rotatably connected to the inner side of the side groove 11, and the top of the first limit plate 12 is elastically connected to the side of the side groove 11 through a second spring 13. The top end of the support rod 14 is in abutting connection with the outer side surface of the first limit plate 12. The support rod 14 is rotatably connected to the inner part of the side wall of the fixed mold 1, and the end of the support rod 14 is connected with a pressing block 15 located outside the fixed mold 1. And the top surface of the pressing block 15 is recessed. Through the downward pressing and installation of the inner mold 20, the first limit plate 12 is automatically rotated inward by extrusion. When the inner mold 20 is pressed downward, the ejection plate 9 is also pressed downward, so that the ejection plate 9 is in contact with the bottom plate 4. At the same time, when the buckle 21 on the outer side of the inner mold 20 corresponds to the side groove 11, the first limit plate 12 is elastically engaged with the buckle 21 under the action of the second spring 13, so that the inner mold 20 and the fixed mold 1 are relatively fixed. At the same time, by pressing the pressing block 15 downward, the support rod 14 rotates, and the top end of the support rod 14 can push and squeeze the top of the first limit plate 12, so that the first limit plate 12 is disengaged from the buckle 21. Under the elastic action of the first spring 10, the ejection plate 9 is pushed upward, and then the inner mold 20 can be automatically ejected.

[0034] Further, a second limit plate 19 is arranged inside the moving mold 3, and the installation structure of the second limit plate 19 inside the moving mold 3 is the same as that of the first limit plate 12 inside the fixed mold 1. The installation structure of the top plate 16 inside the moving mold 3 is the same as that of the bottom plate 4 inside the fixed mold 1. The other half of the mold can be installed inside the moving mold 3 in the same way, so as to facilitate the manufacture of the intervertebral fusion device.

[0035] Embodiment:

[0036] When in use, first, as shown in Figure 1 and Figure 4 , the inner mold 20 with a specific shape is installed inside the fixed mold 1 by directly sinking. By pressing downward, the bottom of the inner mold 20 first squeezes the first limit plate 12, so that the first limit plate 12 automatically rotates and retracts inward to the inner side of the first limit plate 12. After continuous pressing downward, the inner mold 20 presses the ejection plate 9 downward, so that the ejection plate 9 is in contact with the bottom plate 4;

[0037] When the ejection plate 9 is in contact with the bottom plate 4, the buckle 21 on the outer side of the inner mold 20 corresponds to the side groove 11. Under the elastic action of the second spring 13, the first limit plate 12 is engaged with the buckle 21, so that the inner mold 20 and the fixed mold 1 are relatively fixed.

[0038] Similarly, place the other half of the mold inside the moving mold 3 so that the second limiting plate 19 limits it, and at the same time, make the connecting pipe 18 communicate with its internal cavity to facilitate material injection.

[0039] During manufacturing, as Figure 1 and Figure 2 In [reference], the fixed mold 1 and the moving mold 3 are fitted together by the symmetrically arranged telescopic rods 2, and the material is injected through the connecting pipe 18 by the injection device 17. After it is molded and cooled, the moving mold 3 is separated from the fixed mold 1 by the elongation of the telescopic rods 2. At the same time, most of the inner mold 20 of the structure remains inside the fixed mold 1, so that the intervertebral fusion cage stays inside the inner mold 20. By starting the blowing device 8 to blow air into the air nozzle 7, the intervertebral fusion cage inside the inner mold 20 is separated from the inner mold 20, and at the same time, the intervertebral fusion cage is blown out to facilitate discharging.

[0040] When the inner mold 20 needs to be replaced, as Figure 3 In [reference], by pressing down the pressing block 15, the support rod 14 rotates, and the top of the support rod 14 can push against the top of the first limiting plate 12, so that the first limiting plate 12 is disengaged from the buckle 21. Under the elastic action of the first spring 10, the ejecting plate 9 pops up, and then the inner mold 20 can be automatically ejected to facilitate replacement.

[0041] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art. In addition, the orientation nouns such as up, down, left, right, front, and back in the text only represent their relative positions rather than absolute positions.
