Science and technology first of.Compared with traditional processing and manufacturing technology, with rapid prototyping manufacturing, saving material, personalized customization etc.
Advantage, and printing shaping process is conducive to the formation of Ultra-fine Grained even nanometer crystal microstructure, so that the production that printing obtains
Product have superior mechanical performance.The mainstream forming technique of 3D printing technique is fusion sediment rapid shaping, and fusion sediment is again
Fuse is made to deposit, it is that Filamentous heat-fusible materials heating and melting is squeezed there are one the nozzle of minute nozzle by band and gushed out.Heat
Melt material sprays after melting from nozzle, is deposited on and makes on panel or the cured material of preceding layer, and temperature is less than solidification temperature
Start to cure after degree, final finished is formed by the layer upon layer of material.Since it can manufacture arbitrarily complicated part and possess
Preferable printing degree of freedom, increasingly has actual application value in industrial production and daily life.
3D printing technique has and can prepare that material ranges are wide, the recyclable energy saving remanufactured of some materials, part lightweight
The material characteristics of high intensity are measured, and it includes aerospace, national defense and military, medical industry, industry spot and machine to be widely used in
Multiple fields including device people, service trade.And in order to improve the 3D printing of extrudable moulding material, both at home and abroad with regard to printed material sheet
Body has carried out various performance improvements, removes continuous excavation and update for new material, even more utilizes staple fiber, continuous fibre
A variety of strengthening materials such as dimension realize the strength enhancing of printout in all directions by the 3D printing of composite material.
And it is simply installed at one of the tip of heat block mostly for the 3D printing nozzle of the existing extrusion molding of tradition
Runner derived from simple material, major function are forced to squeeze according to channel size when being the friction feeding in print procedure
Go out, and forming situation after extrusion is then substantially dependent upon the setting of material itself and printing technology parameter, and by the pressure of nozzle
Power influences extremely faint.
Invention content
Insufficient present in the above technology in order to overcome, the utility model provides a kind of passing for material extrusion molding
3D printing nozzle is squeezed into formula, the disadvantage that material flowing deformation viscosity is big, meltbility is poor can be effectively improved by the nozzle, well
Meet the requirement of 3D printing industry.
In order to achieve the above object, the utility model adopts the following technical scheme：
A kind of progressive extruding 3D printing nozzle, including in integrated 3D printing nozzle housing, integration 3D printing nozzles
Core, integrated 3D printing nozzles inner core are placed in the inside of integrated 3D printing nozzle housing；Integrated 3D printing nozzle housing and
It is polyurethane thermal-insulation foam plastics insulating layer between integrated 3D printing nozzles inner core.Integrated 3D printing nozzle housing 1, spray
Connection screw thread 2 is equipped with outside 1 upper end of mouth shell, between integrated 3D printing nozzle housing and integration 3D printing nozzle inner cores
For polyurethane thermal-insulation foam plastics insulating layer 3, integrated 3D printing nozzles inner core 5 is placed in integrated 3D printing nozzle housing
Inside, is provided with internal thread 4 on integrated 3D printing nozzles inner core, the progressive extruding 3D printing integrated nozzle of one kind,
Below installation to 3D printing nozzle, material by being in molten state under integrating the temperature control system inside nozzle in 3D printing, then according to
It is secondary to be acted on by integrated 3D printing nozzles inner core and by the intensive shear of inner core internal thread, improve fluid ability and fluid
Viscosity, to print the extruding realized under different power.
The utility model has the advantages that：The variation characteristic of endothecium structure can be utilized to effectively improve to be extruded into
Mobile performance, print density and the properties of shape 3D printing material, are extremely improved traditional prints nozzle and property
It can be promoted, have vital meaning for the 3D printing of extrusion molding material.
