By in product mold made from injection step S3, until injection molding material volume is the 95% of product mold mold cavity volume, stop note
Modeling；
S6, pressure maintaining injection molding material: continuing the intracavitary application pressure of product mold type after filling injection molding material to step S5, be compacted melt,
Increase density；
S7, product are cooling: being cooled down by cooling system for the product mold in step S6, until the intracavitary portion of product mold type
Melt it is cooling in until solid；
S8, product stripping: the product mold in step S7 is separated, so that the intracavitary abjection of the type of product from product mold；
S9, installation product: by the top of zero firewire ferrule embedded product blank, and two trips are fixed on product blank top
Portion two sides.
Making mold former in the present invention, in step S1 can be used Auto CAD, 3DMAX, PRO/E or Solidworks.
Further, the 3D modeling in step S2 uses Simpleware software design, and ScanIP is 3D rendering data
Image viewing, measurement and handling implement provide wide in range selection, and treated, and image can export as STL or point cloud file,
It is built applied to CAD analysis, solution and 3D printing field, while in Simpleware software with grid generation module and curved surface
Mould module, grid generation module be based on Simpleware+FE module design, Simpleware+FE module have it is powerful based on
The mesh generation ability of image, provides high quality solution, and the 3D rendering data after segmentation are converted to manifold volume
Grid, exports and is applied to finite element (FE) or Fluid Mechanics Computation (CFD) software package, and the grid of generation has the interface inhibited
And shared node, it may specify material properties, definition contact, node collection and shell unit, and define CFD boundary condition, pass through reduction
Accelerate the workflow of user in the step of other software draw grid again, curved surface modeling module is designed based on+NURBS, and NURBS is bent
Face modeling module provides a kind of a kind of approach converted from image to CAD data, by creating NURBS(Non-
UniformRationalB-Splines) model, which uses automatic Fitting Surface Creation technology, by ROI
(regionofinterest) area-of-interest is converted to NURBSIGES file, can be directed into CAD software after conversion.
During the 3D modeling of mold former, in order to provide the accuracy of 3D modeling, need the type chamber to mold former,
Type core radial dimension calculates, while being also required to accurate data to the type chamber of mold former, the depth dimensions of type core and supporting.
Following formula can be used for the type chamber radial dimension calculating of mold former:
In formula,For type chamber radial dimension, unit mm,For the basic size of plastic；Unit is mm,For the public affairs of plastic
Difference,For the manufacturing tolerance of die forming part, andValue is/4。
Following formula can be used for the type core radial dimension calculating of mold former:
In formulaFor type core radial dimension, unit mm.
Following formula can be used for the depth of cavity size calculating of mold former:
In formula,For depth of cavity size, unit mm,For the basic size of plastic, unit mm.
Following formula can be used for the type chamber height dimension calculating of mold former:
Before processing and forming, need the water content in raw material being dried to certain percentage hereinafter, because moisture content of raw material
Excessively high the defects of causing vapour flower, delamination, decortication, embrittlement.After material containing moisture enters die cavity, the surface of product can be made to go out
The flaw spot of existing silver silk ribbon shape, in addition can there is a phenomenon where hydrolyzables at high temperature, cause Material degradation, the raw material in step S4 is
PBT plastic particle, and PBT plastic particle is dried using vacuum oven drying.
Due to fountain flow, the plastics macromolecular chain before flow waves is arranged to almost PARALLEL FLOW wavefront, because
For this two strands of molten plastics when crossing, the macromolecular chain of contact surface is parallel to each other, in addition two strands of melten gels are distinct, causes melten gel
Intersectional region is poor in microcosmic upper structural strength, Given this fills injection molding material in step S5 of the invention and uses low speed filling side
Formula, when heat transfer controls low speed filling, shearing rate is lower, and local viscosity is higher, and flow resistance is larger, since thermoplastic materials supplements speed
Rate is slower, and flowing is more slow, keeps heat-conduction effect more obvious, and heat is that cold die wall is taken away rapidly, in addition less amount of viscous
Stagnant heating phenomena, cured layer thickness is thicker, further increases the flow resistance of wall portion thin location.
The effect of packing stage is continu to press, is compacted melt, is increased plastic density (density), to compensate plastics
Shrinkage behavior.In pressure maintaining period, due to having filled up plastics in die cavity, back pressure is higher.In pressure maintaining compacting process, injection molding machine
Screw rod is only capable of making minute movement forward at leisure, and also more slowly, flowing at this moment is referred to as pressure maintaining flowing to the flowing velocity of plastics.
Accelerate since in packing stage, plastics are cooled and solidified by die wall, melt viscosity increase also quickly, therefore the resistance in mold cavity
It is very big.In the later period of pressure maintaining, density of material persistently increases, and plastic also gradually forms, and packing stage will be continued until that cast gate is solid
Change sealing until, the cavity pressure of packing stage reaches peak at this time, at the same in step S6 pressure maintaining period injection molding machine nozzle
Constantly to type chamber feed supplement, to fill due to the volume that product is shunk and is vacated.
In injection forming mold, the design of cooling system is extremely important, this is because moulded plastic products only cool down
It is cured to certain rigidity, is just avoided that plastic products are deformed due to by external force after demoulding, in consideration of it, cooling in step S7
System is cooling water pipe configuration mode, and cooling water pipe, closer to die cavity, caliber is bigger, and number is more, and cooling effect is better, cold
But the time is shorter, while the product cooling time is 10-15 times for filling the injection molding material time in step S7.
Since product is deep-cavity thin-wall, and inner wall is required to be smooth, and product stripping uses stripper plate demoulding side in step S8
Formula, feature are that knockout press is big and uniform, and movement is steady, and nothing significantly leaves trace.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
For personnel it should be appreciated that the present invention is not limited to the above embodiments, described in the above embodiment and specification is only the present invention
Preference, be not intended to limit the invention, without departing from the spirit and scope of the present invention, the present invention also has various
Changes and improvements, these changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by institute
Attached claims and its equivalent thereof.
