The presentation quality of material products accepts the reasons such as performance, and the addition such as some stabilizers, filler is often added in plastic raw materials
Thing, because plastic raw materials are different with the fusing point of additive, the sol in expects pipe is caused to occur failing fully under different operating modes
Fusing, with bulky grain solid matter, when flowing through tiny nozzle bore, easy plug nozzle hole causes not these solid matters
It can normally produce, influence operating efficiency.
The content of the invention
For overcome the deficiencies in the prior art, the invention provides a kind of anti-blocking injection molding machine nozzle.
The present invention is achieved through the following technical solutions：
A kind of anti-blocking injection molding machine nozzle, including spray-hole, the injection channel that is connected with the spray-hole and with the injection
The connected feeding channel of passage, the injection channel are connected with the diameter of feeding channel connecting place more than injection channel with spray-hole
The diameter at place, multiple first screen packs is provided with the feeding channel, multiple first screen packs are staggered, the spray
Penetrate passage and feeding channel connecting place is provided with the second screen pack, second area of filter net and feeding channel cross-sectional area
Identical, first area of filter net is less than the cross-sectional area of feeding channel.
A kind of described anti-blocking injection molding machine nozzle, groove is provided with the feeding channel, the second screen pack passes through institute
State groove to be located in feeding channel, second screen pack has the hand grip portion for stretching out feeding channel, sets at the hand grip portion
There is the first sealing ring.
A kind of described anti-blocking injection molding machine nozzle, the opposite side of the feeding channel correspond to groove and set fluted, institute
State and fluted corresponding plug-in unit is set on the second screen pack, the second sealing ring is provided with the plug-in unit.
A kind of described anti-blocking injection molding machine nozzle, the feeding channel and injection channel are arranged with external member, the set outside
Heating tube is installed in part.
A kind of described anti-blocking injection molding machine nozzle, temperature inductor is provided with the external member.
A kind of described anti-blocking injection molding machine nozzle, the feeding channel are threadedly coupled with injection channel, and the injection is logical
Road is threadedly coupled with spray-hole.
The beneficial effect that the present invention is reached：
The nozzle arrangements of the present invention are simple, by setting multiple first screen packs, intercept the large particulate matter in material, prevent big
Particulate matter causes overall blocking after the first screen pack is blocked, and influences operating efficiency, meanwhile, set the second screen pack to carry out most
Intercept eventually, prevent large particulate matter from flowing into injection channel, and then block spray-hole.
