[0019] This utility model provides the following: Figures 1-4 As shown, a hot melt injection nozzle for an injection molding machine includes a nozzle body 1. The nozzle body 1 has a through-hole material conveying cavity. A threaded groove 2 is formed around the top of the nozzle body 1. The discharge port of the discharge device is located above a filter disc 3. The diameter of the discharge port is smaller than the diameter of the filter disc 3, and a threaded connecting sleeve is fitted around the discharge port. The nozzle body 1 can be threadedly connected to the threaded connecting sleeve through the threaded groove 2, allowing the discharge port and the nozzle body 1 to communicate with each other. Material is then conveyed through the material conveying cavity, and the filter disc 3 filters impurities. Components such as the rotating seat 4 and the insert ring 7 do not contact the material and are positioned between the nozzle body 1 and the threaded connecting sleeve, ensuring the orderly progress of subsequent disassembly. A filter disc 3 is snapped onto the top of the nozzle body 1. Rotating seats 4 are fixedly connected to both ends of the filter disc 3. Limiting strips 5 are rotatably connected to the rotating seats 4. Limiting seats 6, which snap onto the limiting strips 5, are fixedly connected to both sides of the nozzle body 1. An insert ring 7 is snapped onto one side of the top of the nozzle body 1.
