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.

[0017] Please see Figures 1-4 This utility model provides a technical solution: A precision connection injection structure for large injection molded parts includes a frame 1. A mold module 3 and an injection module 4 are located on the top of the frame 1. A disassembly unit 2 is located on one side of the injection module 4 for easy disassembly and cleaning of the injection tube. The disassembly unit 2 includes: The connecting unit 21 is located on one side of the injection module 4 and includes a first injection tube 211 and a second injection tube 212. A fixing ring 215 is fixedly installed on the surface of the second injection tube 212, and five locking blocks 216 are fixedly installed on the outer side of the fixing ring 215. A connecting ring 213 is fixedly installed on the surface of the first injection tube 211, and a locking rod 214 is rotatably installed inside each of the five supports of the connecting ring 213. One end of the locking rod 214 is locked with the locking block 216 to fix the first injection tube 211 and the second injection tube 212, and to achieve quick assembly and disassembly between the second injection tube 212 and the first injection tube 211. The drive unit 22 is disposed on the surface of the first injection tube 211 and is used to rotate the locking rod 214 so that one end of the locking rod 214 is engaged with the locking block 216.

[0018] In this embodiment, the connecting unit 21 includes a threaded sleeve 221 rotatably mounted on the surface of the first injection tube 211. A threaded sleeve 222 is rotatably mounted on the surface of the threaded sleeve 221, and five connecting blocks 223 are circumferentially arrayed on the surface of the threaded sleeve 222. A connecting rod 224 is rotatably mounted inside the connecting block 223, and one end of the connecting rod 224 is rotatably connected to the locking rod 214. The threaded sleeve 222 moves by rotating the threaded sleeve 221, which in turn causes the connecting rod 224 to push the locking rod 214 to rotate.

[0019] The connecting unit 21 includes a threaded rotating sleeve 221, a threaded sleeve 222, a connecting block 223, and a connecting rod 224. By rotating the threaded rotating sleeve 221, the threaded sleeve 222 moves, and the connecting rod 224 pushes the locking rod 214 to rotate, thereby driving the locking rod 214 to engage with the locking block 216, thus completing the rapid fixing and disassembly of the first injection molding tube 211 and the second injection molding tube 212.

[0020] In this embodiment, a rubber gasket 2110 is installed between the first injection tube 211 and the second injection tube 212 to achieve a seal between the first injection tube 211 and the second injection tube 212.

[0021] By installing a rubber gasket 2110 between the first injection tube 211 and the second injection tube 212, a seal is achieved between the two, preventing leakage of injection molding material and ensuring the stability of the injection process and product quality.

[0022] In this embodiment, five fixing blocks 217 are fixedly installed on the surface of the second injection tube 212, and a plug rod 218 is fixedly installed on one side of the fixing block 217. Five insertion holes 219 are opened on one side of the connecting ring 213, and the plug rod 218 is slidably inserted into the inside of the insertion hole 219 to achieve precise docking between the first injection tube 211 and the second injection tube 212.

[0023] By setting a fixing block 217 and a plug 218 on the surface of the second injection tube 212, and opening a plug hole 219 on the connecting ring 213, the plug 218 is inserted into the plug hole 219, thus achieving precise docking between the first injection tube 211 and the second injection tube 212 and avoiding misalignment.

[0024] In this embodiment, five locking rods 214 and five locking blocks 216 engage with each other to achieve multi-point compression and bonding between the first injection tube 211 and the second injection tube 212, thereby improving the bonding tightness between the first injection tube 211 and the second injection tube 212.

[0025] By setting five locking rods 214 and five locking blocks 216 to engage with each other, multi-point extrusion bonding between the first injection tube 211 and the second injection tube 212 is achieved, which improves the tightness and stability of the connection.

[0026] In this embodiment, five supports are fixedly installed on the surface of the threaded sleeve 222 to provide force points for the threaded rotating sleeve 221.

[0027] By fixing five supports on the surface of the threaded sleeve 222, force points are provided for the threaded rotating sleeve 221, which facilitates rotation operation and enhances the convenience of driving.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] During operation, the second injection tube 212 is connected to the first injection tube 211, and the insertion rod 218 is inserted into the insertion hole 219. The user rotates the threaded rotating sleeve 221, which drives the threaded sleeve 222 to move. The threaded sleeve 222 pushes the locking rod 214 to rotate through the connecting rod 224. One end of the locking rod 214 is engaged with the locking block 216, so that the second injection tube 212 and the first injection tube 211 are fixedly connected.
