Problems solved by technology
[0002] The nozzle is an important part of the hot runner mold. The hot runner mold uses a heating device to keep the raw material melt in the runner from solidifying. The raw material is injected from the injection machine to the main injection port and injected into the mold cavity through the nozzle through the splitter plate. Due to the complex structure of the nozzle , easy to block and cannot be cleaned, it is not only difficult to replace, but also usually causes equipment shutdown, which greatly reduces work efficiency and brings great losses to assembly line enterprises

Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.
[0024] refer to Figure 1-4 As shown, a hot runner cleaning structure includes a switching mechanism, a cleaning mechanism and a nozzle body 5. One end of the switching mechanism is connected to the runner port 11 of the hot runner 1, and two nozzle bodies 5 are provided at the other end. The switching mechanism can Make the flow channel port 11 switch between any one of the two nozzle bodies 5;
[0025] The cleaning mechanism is arranged on the switching mechanism, and the cleaning mechanism cleans the nozzle body 5 that is not connected to the flow channel opening 11 after switching by the switching mechanism.
[0026] In the present invention, a switching mechanism is provided...

The invention relates to the technical field of hot runners, in particular to a hot runner cleaning structure. A switching mechanism is arranged between a hot runner and nozzle bodies, the nozzle bodies are switched through the switching mechanism, when a spraying hole is blocked, the nozzle bodies can be rapidly switched, the situation that shutdown needs to be carried out for replacing a nozzleis solved, the abnormal processing period is effectively shortened, and the working efficiency is improved; meanwhile, an arranged cleaning mechanism can be used for cleaning the nozzle body switchedby the switching mechanism or cleaning blockages; and under the driving of the switching mechanism, the two nozzle bodies can play a mutual standby role, the blocked nozzle bodies can be cleaned on line, so that the convenience of the equipment during working is effectively improved.
