[0003] After an injection molding operation is completed on the injection molding machine, it is inevitable that some plastic will remain in the nozzle. If the production interval is long or the operation is improper, this remaining plastic will gradually solidify, making it inconvenient to disassemble the nozzle from the injection molding machine. Therefore, there is a problem of inconvenience in replacing the nozzle. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] As Figure 1 - Figure 3 shown, an adjustable end connector of an injection molding machine includes the rear end 1 of an injection molding machine spray gun, a fixing mechanism 2, a disassembly mechanism 3 and a nozzle 4. The fixing mechanism 2 is slidably connected to the outer surface of the rear end 1 of the injection molding machine spray gun. The disassembly mechanism 3 is fixedly connected to the outer surface of the rear end 1 of the injection molding machine spray gun. The nozzle 4 is slidably connected to the outer surface of the disassembly mechanism 3. The disassembly mechanism 3 includes an electric telescopic rod 304 fixedly connected to the outer surface of the rear end 1 of the injection molding machine spray gun. The output end of the electric telescopic rod 304 is fixedly connected with a sliding frame 301. A clamping frame 302 is slidably connected to the inner side surface of the sliding frame 301. A plurality of resistance heating wires 307 are fixedly connected to the inner wall of the clamping frame 302.
[0023] In order to replace the nozzle 4, the disassembly mechanism 3 further includes a bidirectional threaded rod 308 rotatably connected to the inner wall of the sliding frame 301. One end of the bidirectional threaded rod 308 passes through the outer surface of the sliding frame 301 and is fixedly connected with a knob 303. The outer surface of the bidirectional threaded rod 308 is threadedly connected with the clamping frame 302. By rotating the knob 303, the knob 303 drives the bidirectional threaded rod 308 to rotate, so that the two clamping frames 302 can slide in opposite directions. A limiting rod 305 is fixedly connected to the inner wall of the sliding frame 301. The outer surface of the limiting rod 305 is slidably connected to the outer surface of the clamping frame 302. The limiting rod 305 is convenient for limiting the clamping frame 302, so that the clamping frame 302 can stably slide along the outer surface of the limiting rod 305. A plurality of limiting rings 306 are fixedly connected to the outer surface of the limiting rod 305. The outer surface of the limiting ring 306 is not in contact with the inner wall of the sliding frame 301. The limiting ring 306 is convenient for limiting the upper end of the clamping frame 302 and preventing the clamping frame 302 from separating from the bidirectional threaded rod 308.
[0024] It is worth mentioning that when the resistance heating wire 307 is started, the resistance heating wire 307 heats the outer surface of the clamping frame 302, and through heat transfer, it is convenient to heat the nozzle 4, so that the solidified plastic in the nozzle 4 melts. Then, the electric telescopic rod 304 is started, and the output end of the electric telescopic rod 304 drives the sliding frame 301 to slide away from the rear end 1 of the injection molding machine spray gun, thereby facilitating the separation of the nozzle 4 from the rear end 1 of the injection molding machine spray gun. Then, the knob 303 is rotated, and the knob 303 drives the bidirectional threaded rod 308 to rotate. The rotation of the bidirectional threaded rod 308 drives the two groups of clamping frames 302 to move in opposite directions, facilitating the removal of the nozzle 4 from between the two groups of clamping frames 302, and thus facilitating the disassembly and replacement of the nozzle 4.
[0025] In order to fix the nozzle 4, the fixing mechanism 2 includes a limiting plate 201 slidably connected to the outer surface of the rear end 1 of the injection molding machine spray gun. The outer surface of the limiting plate 201 is fixedly connected to the outer surface of the sliding frame 301, and a plurality of threaded holes 202 are opened on the outer surface of the limiting plate 201. A limiting chute is opened on the outer surface of the rear end 1 of the injection molding machine spray gun. By sliding the limiting plate 201 in the chute on the outer surface of the rear end 1 of the injection molding machine spray gun, it is convenient to limit the sliding frame 301. A fastening bolt 203 is threadedly connected to the outer surface of the threaded hole 202, and the outer surface of the fastening bolt 203 is threadedly connected to the outer surface of the rear end 1 of the injection molding machine spray gun. By connecting the fastening bolt 203 to the threaded hole 202 opened on the outer surface of the limiting plate 201, it is convenient to fix the limiting plate 201.
[0026] It is worth mentioning that by rotating the fastening bolt 203, the outer surface of the fastening bolt 203 is threadedly connected to the outer surface of the threaded hole 202, thereby facilitating the limitation of the limiting plate 201 and, to a certain extent, facilitating the fixation of the sliding frame 301.
[0027] Working principle: By rotating the fastening bolt 203, the outer surface of the fastening bolt 203 is separated from the threaded hole 202, thereby facilitating the release of the limitation on the limiting plate 201, so that the outer surface of the limiting plate 201 can slide on the outer surface of the rear end 1 of the injection molding machine spray gun. When the resistance heating wire 307 is started, the resistance heating wire 307 heats the outer surface of the clamping frame 302, and through heat transfer, it is convenient to heat the nozzle 4, so that the solidified plastic in the nozzle 4 melts. Then, the electric telescopic rod 304 is started, and the output end of the electric telescopic rod 304 drives the sliding frame 301 to slide away from the rear end 1 of the injection molding machine spray gun, thereby facilitating the separation of the nozzle 4 from the rear end 1 of the injection molding machine spray gun. Then, the knob 303 is rotated, and the knob 303 drives the bidirectional threaded rod 308 to rotate. The rotation of the bidirectional threaded rod 308 drives the two groups of clamping frames 302 to move in opposite directions, facilitating the removal of the nozzle 4 from between the two groups of clamping frames 302, and thus facilitating the disassembly and replacement of the nozzle 4.
