[0038] Example: Please refer to Figures 1 to 8 as shown:

[0039] The present invention provides a cage-type shell load-bearing structure that is convenient for combined disassembly and assembly, including an annular support frame 1;

[0040] Refer to Figure 1 and Figure 2 . The annular support frame 1 is an annular support structure formed by connecting the left half-ring 101 and the right half-ring 102 through a transverse support rod 103. Four connection card slots 10101 are opened in the left side wall of the left half-ring 101, and four connection blocks 10201 are provided on the right side wall of the right half-ring 102. The two annular support frames 1 are spliced by engaging the connection blocks 10201 in the connection card slots 10101. Six transverse support rods 103 are arranged in an annular array. The two ends of the transverse support rod 103 are respectively connected to the left half-ring 101 and the right half-ring 102. The transverse support rod 103 at the front and rear middle of the left half-ring 101 and the right half-ring 102 is hollow and communicates with the pouring pipe 104. The annular support frames 1 are connected by fixing bolts 2. When in use, when two annular support frames 1 need to be connected, the right half-ring 102 of the previous annular support frame 1 is connected to the left half-ring 101 of the next annular support frame 1 through the connection card slots 10101 and the connection blocks 10201, and fixed by the fixing bolts 2, which can make the connection of the two annular support frames 1 more firm and facilitate providing a better support and protection effect. The annular support frame 1 provides support and protection for the internal integral mold 7 to prevent the integral mold 7 from being impacted externally.

[0041] Refer to Figure 2 and Figure 8, the closed support 3 is connected to one side of the annular support frame 1 through the fixing bolt 2. There are two wax injection ports 301 arranged in the middle of the side wall of the closed support 3. The inner side wall of the wax injection port 301 is inclined and provided with a slot. A fixing knob 8 is rotatably connected to the middle of the closed support 3. When in use, the closed support 3 is installed at both ends of the annular support frame 1 through the fixing bolt 2, so that the closed support 3 and the annular support frame 1 form a circular ring, thereby improving the load-bearing capacity of the annular support frame 1 and preventing the annular support frame 1 from deforming due to extrusion. And the wax injection port 301 of the closed support 3 is communicated with the hollow transverse support rod 103, which is convenient for injecting wax oil into the integral mold 7 through the pouring pipe 104 subsequently.

[0042] Refer to Figure 5 and Figure 6 , the injection pipe connector 4 is inserted into the middle of the side wall of the closed support 3. One end of the outer side wall of the injection pipe connector 4 is inclined and provided with an insertion block. One end of the injection pipe connector 4 is inserted into the wax injection port 301. The outer side wall of the injection pipe connector 4 and the insertion block are fitted with the inner side wall and the slot of the wax injection port 301. An anti-detachment convex block 401 is arranged on the outer side wall of the injection pipe connector 4. When in use, by inserting the injection pipe connector 4 into the wax injection port 301, it is convenient to perform the wax injection operation on the integral mold 7 and improve the forming effect of the wax mold.

[0043] Refer to Figure 3 and Figure 4 , the locking collar 5 is rotatably connected to the middle of the side wall of the closed support 3. The locking collar 5 is in a semi-open cylindrical shape. Four T-shaped lock block chutes 501 are opened in the inner side wall of the locking collar 5. The locking collar 5 is rotatably connected to the outside of the wax injection port 301. An elastic lock block 6 is slidably connected in the inner side wall of the locking collar 5. The elastic lock block 6 is slidably connected in the lock block chute 501 of the locking collar 5. A spring 601 is arranged between the top of the elastic lock block 6 and the side wall of the lock block chute 501. The bottom of the elastic lock block 6 is clamped on one side of the anti-detachment convex block 401 of the injection pipe connector 4. When in use, when the injection pipe connector 4 is inserted into the wax injection port 301, the locking collar 5 is pulled forward so that the locking collar 5 is sleeved on the outside of the injection pipe connector 4. The locking collar 5 is clamped at the anti-detachment convex block 401 of the injection pipe connector 4 through the elastic lock block 6 slidably connected in the inner side wall to improve the connection firmness and prevent the injection pipe connector 4 from accidentally falling off.

[0044] Refer to Figure 1 and Figure 2, The integral mold 7 is disposed inside the annular support frame 1. The integral mold 7 includes: a left mold 701 and a right mold 702. Four connecting bumps 70101 are welded on the right side wall of the left mold 701, and four connecting grooves 70201 are formed in the left side wall of the right mold 702. During use, since the integral mold 7 is composed of the left mold 701 and the right mold 702, the integral mold 7 can be modularly assembled, facilitating arbitrary changes in the degree and size of the integral mold 7, thereby improving the scope of application and making the adaptability broader.

[0045] Refer to Figure 7 and Figure 8 , The fixing knob 8 is rotatably connected to the middle of the closed support frame 3 through a rotary connection block 801 provided on one side. One end of the fixing knob 8 is provided with a thread. During use, by rotating the fixing knob 8, the thread at one end of the fixing knob 8 is screwed into the side wall of the integral mold 7, thereby fixing the integral mold 7 and preventing the integral mold 7 from shaking in the annular support frame 1, facilitating the improvement of the stability of the integral mold 7.

[0046] Specific usage method and function of this embodiment:

[0047] When the present invention is in use, first, the right half ring 102 of the previous annular support frame 1 is connected to the left half ring 101 of the subsequent annular support frame 1 through the connection slot 10101 and the connection block 10201, and then fixed through the fixing bolt 2, enabling the length of the shell bearing structure to be changed. Then, the left mold 701 and the right mold 702 of the integral mold 7 are assembled and placed into the annular support frame 1. Next, the closed support frame 3 is installed at both ends of the annular support frame 1 through the fixing bolt 2, so that the closed support frame 3 and the annular support frame 1 form a circular ring, thereby improving the load-bearing capacity of the annular support frame 1. Then, by rotating the fixing knob 8, the thread at one end of the fixing knob 8 is screwed into the side wall of the integral mold 7 to fix the integral mold 7. Subsequently, the injection tube connector 4 is inserted into the wax injection port 301 and the locking collar 5 is pulled forward, so that the locking collar 5 is sleeved outside the injection tube connector 4. The locking collar 5 is stuck at the anti-disengagement protrusion 401 of the injection tube connector 4 through the elastic locking block 6 slidably connected to the inner side wall to improve the connection firmness.
