The subjects such as art.The basic principle of 3D printing technique is " successively print, be layering ", that is, first passes through CAD software and generate three-dimensional mould
Type, then by host computer Slice Software（Such as cura, Repetier-Host, RetinaCreate etc.）Layering is carried out to it to cut
Piece and planning path, the G-code files of generation are imported to the next machine controller, then control 3D printing equipment by controller
Successively reproduce three-dimensional entity model.
Using 3D printing rapid shaping technique as core, there are the 3D formers of different printing principles, wherein melting is heavy
Product molding（FDM）Equipment is easy to use by its, it is easy to operate and as the hot spot applied instantly.Its hardware core is that hot melt is beaten
Nozzle is printed, printed material is mostly hot-melt plastic.In print procedure, under the control of the controller, by feed mechanism by hot melt
Plastics push to printing head, then the extrusion molding using nozzle high temperature melting.
Currently, forming temperature is at an early stage of development in 300 DEG C or more of high temperature FDM 3D forming techniques, many ask still is faced
Topic, one of them is exactly the contraction problem of moulding material.The printed material of high temperature FDM 3D printings is after molding, because temperature is rapid
Drop, generally shrinks bigger.First molding printable layer is first shunk, and the printable layer after-contraction of aftershaping causes between layers
It shrinks inconsistent, easily causes delamination, influence the quality of model.Therefore, it realizes that collaboration between layers is shunk, avoids layer
Between cracking be the key that ensure high temperature 3D printing be smoothed out.
Invention content
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of 3D printing constant-temperature molding cavity,
Its is simple and reasonable, and material model levels in print procedure can effectively be avoided to shrink the generation of inconsistent phenomenon.
To achieve the above object, the present invention uses following technical scheme：
A kind of 3D printing constant-temperature molding cavity of the present invention, including molding cavity module and shaped platform module, institute
It states molding cavity module to include heating collar and cover at main heat shield outside the heating collar, the shaped platform module includes
Hott bed and the molded substrate being set on the hott bed, the main heat shield are set on the molded substrate.
Further, downside thermal insulation board is provided between the bottom and the molded substrate of the main heat shield.
Further, the bottom of the heating collar is undertaken on the downside thermal insulation board.
Further, the molding cavity module further includes the upside heat shield being covered on the upside of the main heat shield.
Further, the upside heat shield movable guard is set to the outside of the main heat shield.
Further, the molding cavity module further includes the upside insulation cover with the upside heat shield corresponding matching,
The upside insulation cover hangs on the surface of the upside heat shield and is fixedly connected with the nozzle of printer.
Further, the shaped platform module further includes substrate supporting device and hand nutting；The hand nutting passes through
The hott bed and the molded substrate are worn, and the hott bed and the molded substrate are fixed on the substrate supporting device.
Beneficial effects of the present invention are：3D printing constant-temperature molding cavity provided by the invention when work, on the one hand passes through control
Heating collar electrified regulation processed makes the inner cavity of molding cavity module generate high temperature, and the material model to print provides suitable height
Warm constant environment, to avoid the material model levels in 3D printer print procedure from shrinking inconsistent problem；Another party
Face is heated by hott bed for molded substrate, while also having partial heat to be passed to by the form of heat radiation in molding cavity module
Molded substrate can effectively reduce the thermal contraction that material model bottom occurs in print procedure.After printing, heating collar and heat
Bed power-off stops heating so that the inner cavity of molding cavity module and the temperature of molded substrate are gradually reduced, and promote material model whole
Body declines with temperature and cooperates with and shrink, because without delamination, ensure that model quality.Structure of the invention setting is simple
Rationally.

Specific implementation mode
The present invention will be further described below with reference to the drawings.
A kind of 3D printing constant-temperature molding cavity as shown in Figure 1, including molding cavity module and shaped platform module, molding
Cavity module includes heating collar 11 and covers at main heat shield 12 outside heating collar 11, when printing, passes through and controls heating collar 11
Electrified regulation makes the inner cavity of molding cavity module generate high temperature, and the material model to print provides suitable high temperature constant ring
Border, to avoid the material model levels occurred in 3D printer print procedure from shrinking inconsistent problem.Main heat shield
On the one hand 12 agent structure as molding cavity module is used to provide print space to material model, on the other hand then be used for
So that the inner cavity of molding cavity module is isolated with external environment, to reduce scattering and disappearing for heat, ensures molding cavity module internal cavity temperature
Stabilization.
Shaped platform module includes hott bed 21 and the molded substrate being set on hott bed 21 22, and main heat shield 12 is set into
In type substrate 22, when printing, the bottom of material model is bonded on molded substrate 22, is at this time molded substrate 22 by hott bed 21
Heating, while molding cavity module internal cavity also has partial heat, to molded substrate 22, can be effectively reduced by radiant heat transfer
Model bottom is heat-shrinked caused by being in direct contact with molded substrate 22 in print procedure.
After printing, heating collar 11 and the power-off of hott bed 21 stop heating so that the inner cavity of molding cavity module and molding
The temperature of substrate 22 is gradually reduced, and is promoted whole decline with temperature of material model and is cooperateed with and shrink, because being opened without interlayer
It splits, ensure that model quality.
Downside thermal insulation board 13 is provided between the bottom and molded substrate 22 of main heat shield 12, it is preferable that heating collar 11
Bottom is undertaken on the thermal insulation board 13 of downside.Downside thermal insulation board 13 separates heating collar 11 and molded substrate 22, prevents heating collar 11
