Both machines inject molten plastic into a mold and then cool it to form. However, when the injection molding machine is in use, the nozzle may become clogged. For example, a common material problem is that if metal debris, dust or degraded plastic particles are mixed into the raw materials, they will carbonize and clog the nozzle at high temperatures. At this time, the staff needs to remove the nozzle from the feed barrel. The nozzle is usually fixed on the feed barrel, and the surrounding space of the installation position is small, which makes maintenance more troublesome. Summary of the invention
