[0002] With the development of society, plastic products are more and more widely used in people's life, and daily necessities such as electronic products are applied to plastic products, among which injection molding is one of the important means of manufacturing plastic products. The nozzle is an important medium for transmitting plastic raw materials from the injection molding machine to the mold during the injection molding process.

[0003] After searching, the patent number CN201821808023.5 discloses a plastic injection molding machine nozzle structure. Although the device uses a motor to drive the ball to rotate when in use, by adjusting the relative position relationship between the second flow channel and the connecting hole, the resistance of the plastic raw materials during the flow process is adjusted, thereby realizing the control of the flow in the first flow channel, simplifying the operation process when controlling the flow, and promoting the smoothness of the injection molding process. At the same time, the left end of the communication pipe is set as an arc surface, which helps the free rotation of the ball in the transmission pipe, so that the ball has the dual functions of adjusting the flow and closing the flow channel. However, the device is complex in design, especially the precise fit between multiple components, which makes it difficult to completely disassemble and clean during daily use. This may cause plastic residues to accumulate inside the nozzle, which not only affects the quality of plastic products in the long run, but also may cause the nozzle to be blocked or damaged. Due to the difficulty in cleaning, the nozzle may need to be replaced more frequently, or professional maintenance personnel may need to perform complex disassembly and cleaning work, thereby increasing the maintenance cost and time cost.
