When using the injection nozzle, directly install the injection nozzle at the discharge port of the injection molding machine, and then the heated plastic can be well injected into the mold.

[0028] Refer to Figure 2 and Figure 3, the heat preservation device 2 includes a heating wire 201, the heating wire 201 is sleeved on the surface of the nozzle body 1, a first semi-circular plate 202 and a second semi-circular plate 203 are sleeved on the surface of the nozzle body 1. When using the heat preservation device 2, by energizing the heating wire 201, the heating wire 201 heats the nozzle body 1, and then the first semi-circular plate 202 and the second semi-circular plate 203 are sleeved on the surface of the heating wire 201, which improves the heating efficiency of the heating wire 201 to a certain extent. In this way, the plastic entering the inside of the nozzle body 1 can be kept warm to a certain extent. A rectangular strip 204 is fixedly connected to the top of the second semi-circular plate 203, and the rectangular strip 204 slidably penetrates and is inserted into the bottom of the first semi-circular plate 202. One side of the first semi-circular plate 202 is fixedly connected to a fixing rod 205, one end of the fixing rod 205 is slidably inserted into one side of the rectangular strip 204, a first spring 206 is sleeved on the surface of the fixing rod 205, one end of the first spring 206 is fixedly connected to one end of the fixing rod 205, and the end of the first spring 206 close to the fixing rod 205 is fixedly connected to one side of the first semi-circular plate 202. After passing the rectangular strip 204 through the first semi-circular plate 202, the fixing rod 205 passes through one side of the first semi-circular plate 202 and is inserted into one side of the rectangular strip 204. Then, the fixing rod 205 is pulled towards the rectangular strip 204 by the first spring 206, so that the fixing rod 205 is well restricted inside the rectangular strip 204, and thus the rectangular strip 204 is well fixed inside the first semi-circular plate 202. In this way, the first semi-circular plate 202 and the second semi-circular plate 203 can be restricted on the surface of the heating wire 201. A rock wool sleeve 209 is sleeved on the surfaces of the first semi-circular plate 202 and the second semi-circular plate 203. A fixing groove 211 is opened at the top of the rock wool sleeve 209. By sleeving the rock wool sleeve 209 on the surfaces of the first semi-circular plate 202 and the second semi-circular plate 203, because the material of the rock wool sleeve 209 is rock wool and the internal structure of the rock wool is porous, it can play a certain heat preservation effect. A sliding groove 207 is opened at one end of the nozzle body 1, a clamping block 208 is slidably connected to the inner wall of the sliding groove 207, one end of the clamping block 208 is slidably connected to the inner wall of the fixing groove 211, and a second spring 210 is fixedly connected to the bottom of the inner wall of the sliding groove 207. The end of the second spring 210 close to the sliding groove 207 is fixedly connected to the bottom of the clamping block 208. By controlling the clamping block 208 to slide inside the sliding groove 207, the clamping block 208 slides into the fixing groove 211, and the clamping block 208 is pulled towards the sliding groove 207 by the second spring 210, so that the clamping block 208 is restricted inside the fixing groove 211.

[0029] Refer to Figure 4, the shielding device 3 includes a support bar 301. One side of the support bar 301 is fixedly connected to the rock wool sleeve 209. One end of the support bar 301 is rotatably inserted with a rotating rod 302. The end of the rotating rod 302 away from the support bar 301 is fixedly connected to a baffle 303. When using the shielding device 3, manually drive the rotating rod 302 to rotate at one end of the support bar 301 through the baffle 303. Then, the excess plastic at one end of the nozzle body 1 can be scraped off by the baffle 303. Then, set the baffle 303 at the discharge port, so that one end of the nozzle body 1 can be blocked, and to a certain extent, dust can be prevented from entering the inside of the nozzle body 1. A round block 304 is fixedly connected to the surface of the support bar 301. A round groove 305 is opened on one side of the round block 304. The inner wall of the round groove 305 is slidably connected to a limiting rod 306. The end of the limiting rod 306 away from the round groove 305 is fixedly connected to one side of the baffle 303. The limiting rod 306 slides inside the round groove 305, so that the baffle 303 can drive the rotating rod 302 to rotate well. A rectangular plate 307 is fixedly connected to the top of the round block 304. A sliding rod 308 is slidably inserted through the top of the rectangular plate 307. The bottom of the sliding rod 308 is fixedly connected to a U-shaped plate 309. The U-shaped plate 309 is sleeved on the surface of the limiting rod 306. Control the sliding rod 308 to be inserted into the top of the rectangular plate 307, and then sleeve the U-shaped plate 309 on the top of the sliding rod 308. In this way, the limiting rod 306 can be well restricted inside the round groove 305, and then the baffle 303 can be restricted at the discharge port of one end of the nozzle body 1. A third spring 310 is sleeved on the surface of the sliding rod 308. One end of the third spring 310 is fixedly connected to the top of the sliding rod 308. The end of the third spring 310 close to the sliding rod 308 is fixedly connected to the top of the rectangular plate 307. By pulling the sliding rod 308 in the direction close to the rectangular plate 307 through the third spring 310, the U-shaped plate 309 is restricted on the surface of the limiting rod 306.

[0030] Working principle: When using the injection nozzle, directly install the injection nozzle at the discharge port of the injection molding machine, and then it can well inject the heated plastic into the interior of the mold. When using the heat preservation device 2, by energizing the heating wire 201, the heating wire 201 heats the nozzle body 1. Then, the first semi-circular plate 202 and the second semi-circular plate 203 are sleeved on the surface of the heating wire 201. After passing the rectangular strip 204 through the first semi-circular plate 202, the fixing rod 205 passes through one side of the first semi-circular plate 202 and is inserted into one side of the rectangular strip 204. Then, the fixing rod 205 is pulled towards the rectangular strip 204 by the first spring 206, so that the fixing rod 205 is well restricted inside the rectangular strip 204, and thus the rectangular strip 204 is well fixed inside the first semi-circular plate 202. In this way, the first semi-circular plate 202 and the second semi-circular plate 203 can be restricted on the surface of the heating wire 201, improving the heating efficiency of the heating wire 201 to a certain extent. The rock wool sleeve 209 is sleeved on the surface of the first semi-circular plate 202 and the second semi-circular plate 203. Control the sliding of the clamping block 208 inside the sliding groove 207 so that the clamping block 208 slides into the fixing groove 211. The clamping block 208 is pulled towards the sliding groove 207 by the second spring 210, and then the clamping block 208 is restricted inside the fixing groove 211. Because the material of the rock wool sleeve 209 is rock wool and the internal structure of the rock wool is loose and porous, it can play a certain heat preservation effect. In this way, to a certain extent, the plastic entering the interior of the nozzle body 1 can be insulated to a certain extent. When using the shielding device 3, manually drive the rotating rod 302 to rotate at one end of the support bar 301 through the baffle 303. Then, the excess plastic at one end of the nozzle body 1 can be scraped off by the baffle 303. Then, the baffle 303 is arranged at the discharge port. Control the sliding rod 308 to be inserted into the top of the rectangular plate 307, and then the U-shaped plate 309 is sleeved on the top of the sliding rod 308. In this way, the limiting rod 306 can be well restricted inside the circular groove 305. The sliding rod 308 is pulled towards the rectangular plate 307 by the third spring 310, and then the U-shaped plate 309 is restricted on the surface of the limiting rod 306, and thus the baffle 303 is restricted at the discharge port at one end of the nozzle body 1. In this way, one end of the nozzle body 1 can be blocked, and to a certain extent, dust can be prevented from entering the interior of the nozzle body 1.
