[0002] The nozzle of a self-closed injection molding machine is a specially designed nozzle that is suitable for situations where it is necessary to prevent plastic from overflowing or leaking during the injection molding process. It usually has a sealing ring or other sealing device that can completely close the nozzle during the injection process to prevent the plastic from flowing out. The nozzle of a self-closed injection molding machine can also reduce the oxidation and volatilization of the plastic when the nozzle is closed, thereby improving the surface quality and appearance of the product. The nozzle of a self-closed injection molding machine can effectively reduce the scrap rate, improve production efficiency and product quality.

[0003] Most of the self-enclosed injection molding machines on the market still have the following problems when in use:

[0004] 1. The nozzle of the traditional self-enclosed injection molding machine needs to ensure that the material is always in a state that can be injected during the injection molding process. However, if more injection molded parts are to be injected, the subsequent injection molded parts may be injected unsmoothly due to the re-condensation of the molten plastic particles, resulting in too many waste parts, which is not convenient for long-term injection molding process;

[0005] 2. Most self-enclosed injection molding machine nozzles may be hit by external forces when they are idle and may cause damage to the nozzle components, which will affect the aesthetics of the final injection molded product during use and have poor protection effect. Utility Model Content
