The features such as high, is widely used in machining.The material melts of injection molding machine are realized by melten gel cartridge module.?
Uniform injecting products are produced under certain back pressure, especially for the injection molding of the good plastic material of mobility, and in order to
Guarantee injection molding effect, the nozzle for needing to use can be filtered the plastic material of injection molding.And existing nozzle has following ask
Topic：1, since temperature is unstable, plastic raw materials is caused to solidify in nozzle, then nozzle is cleaned, and due to nozzle
Moulding, cleaning difficulty are big；2, nozzle interior structure causes raw material ejection to receive resistance, influences to be molded effect；3, when being molded, due to
Plastic raw materials of the inside by melting can generate toxic gas, if directly distributing into working environment, influence worker's health.
Utility model content
In order to solve the above technical problems, the utility model proposes a kind of injection molding machine nozzle, including nozzle body, the spray
Mouth body exterior is equipped with shell, and the outer casing inner wall is equipped with polytetrafluoroethylene ethylene layer, and is bonded with the nozzle body inner wall, described
Polytetrafluoroethylene ethylene layer is equipped with micropore；Cleaning hole is disposed on the nozzle body inner wall；It is set outside the nozzle body
There is external screw thread, the shell is combined on the external screw thread, is equipped with several outgassing grooves along the shell in the shell, described
Heating tube is equipped in outgassing groove.
Preferably, the nozzle body includes feed end and ejection end, is equipped with filter screen at the feed end.
Preferably, the cleaning hole is equipped with arcwall face close to the side of the ejection end.
Preferably, the filter screen includes two disks disposed in parallel, and the disc centre is equipped with strainer, the disk
Between pass through ring set connect；The disk circumference is equipped with fixture block, and the fixture block is sticked in the nozzle body.
The utility model proposes injection molding machine nozzle have following beneficial effect：1, it is provided with shell, it can be with head body
Separation when cleaning, is heated by shell, after capable of being heated and softened to the plastics of solidified inside, then will be internal by tool
Nozzle body cleaning hole in set plastic cleaned；2, arcwall face is arranged close to the side of ejiction opening in cleaning hole, protects
When demonstrate,proving fused raw material ejection, reduce the resistance between cleaning hole, guarantees injection molding effect；3, it is provided with outgassing groove, can will be given up
Gas concentrates discharge.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described.
Fig. 1 is the structural schematic diagram of the utility model；

Wherein, 1, nozzle body；2, shell；3, polytetrafluoroethylene ethylene layer；4, hole is cleaned；5, external screw thread；6, outgassing groove；7, add
Heat pipe；8, ejection end；9, feed end；10, arcwall face；11, disk；12, strainer；13, ring set；14, fixture block.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
As shown in Figure 1 and Figure 2, the utility model proposes a kind of injection molding machine nozzle, including nozzle body 1, the nozzle sheets
Shell 2 is equipped with outside body 1,2 inner wall of shell is equipped with polytetrafluoroethylene ethylene layer 3, and is bonded with 1 inner wall of nozzle body, institute
Polytetrafluoroethylene ethylene layer 3 is stated equipped with micropore, nozzle body 1 is bonded setting with shell 2, and by setting outside nozzle body 1
Some external screw threads 5, shell 2 are combined on the external screw thread 5, realize that the two is relatively fixed, in order to washer jet of being more convenient for
Coagulated substance in ontology 1 is disposed with cleaning hole 4, when injection molding, injection raw material meeting on 1 inner wall of nozzle body
Fill part cleans hole 4, bonds between the fused raw material and shell 2 cleaned in hole 4 in order to prevent, and polytetrafluoroethylene ethylene layer 3 is arranged,
It due to its self-lubrication, will not be bonded with fused raw material, can more help and be removed with by shell 2, wherein cleaning hole 4 is being molded
In the process, resistance can be generated to injection raw material, so, the cleaning hole 4 is equipped with arcwall face close to the side of the ejection end 8
10, it with the flow direction of raw material, can be flowed along arcwall face 10, reduce the resistance to raw material, guarantee injection molding effect.
Wherein it is noted that in order to guarantee to be easier to clean, it is equipped with heating tube 7 in the outgassing groove 6, heating tube 7 is
