Heating tube is installed in part.
A kind of nozzle of described injection molding machine of plastic, the second valve is provided with the spray-hole.
A kind of nozzle of described injection molding machine of plastic, the injection channel are provided with screen pack with feeding channel connecting place.
A kind of nozzle of described injection molding machine of plastic, is provided with groove on the feeding channel, and screen pack is through described logical
Groove is located in feeding channel, and the screen pack has the hand grip portion for stretching out feeding channel, and it is close to be provided with first at the hand grip portion
Seal.
A kind of nozzle of described injection molding machine of plastic, the opposite side of the feeding channel correspond to groove and set fluted, institute
State and fluted corresponding plug-in unit is set on screen pack, the second sealing ring is provided with the plug-in unit.
A kind of nozzle of described injection molding machine of plastic, the feeding channel are threadedly coupled with injection channel, the spray-hole
It is threadedly coupled with injection channel.
The beneficial effect that the present invention is reached：
The nozzle of the present invention is by setting discharging opening and air extractor, and after feeding is stopped, the material that nozzle interior remains is led
Storage tank is flow to, reduces the overflow of material, meanwhile, prevent unnecessary material from being condensed at spray-hole, result in blockage；And storage tank
Interior material is repeatable to be utilized, cost-effective；Meanwhile by setting heating tube to ensure the temperature of material, prevent that material is cold too early
It is solidifying to cause spray nozzle clogging.
