Description

A kind of double-decker inside gadget injection moulding process
Technical field
The present invention relates to injection molding technology field, more particularly to a kind of double-decker inside gadget injection moulding process.
Background technology
With continuing to develop for automobile industry, the lifting of automotive trim quality turns into the emphasis of automotive development.In automobile Field, moccasin injection cladding process belongs to a kind of new technology type, and the surface sense of automotive trim can be improved using the technique Know quality.
At present, domestic and foreign scholars have done correlative study from process aspect to being molded overmolded technology.Guest's rising sun is flat to be analyzed The injection defect that overmolded product easily occurs in process of production, and carried out by the selection of mold design and molding parameter The control of forming defect.Chang etc. optimizes plastic system by combining field mouthful (Taguchi) method and CAE simulation analysis The cubical contraction of product.Iniesta etc. combines artificial neural network and artificial bee colony algorithm optimization injection-mold process parameter, To reach the purpose for the buckling deformation amount for reducing plastic products.Fan Yabo etc. using automotive trim panel as research object, with reference to The technological parameter such as moldflow simulation analysis and orthogonal experiment optimization filling time, mold temperature, melt temperature.But it is big The parameter that part research institute is directed to is less, and for influenceing the technological parameter that moccasin is molded coating member performance to lack, system is deep to grind Study carefully.
《The injection cladding process research of automotive upholstery moccasin》One text, as research object, is based on using plaque on certain automobile door plate Moldflow softwares establish plaque skeleton and clad FEM model, complete sunykatuib analysis scheme design and The setting of major parameter, has carried out the molding simulation analysis of upper plaque skeleton and clad, according to analog result to upper plaque Mouldability is analyzed, checked product with the presence or absence of it is short penetrate, shrink mark, weld mark, the forming defect such as contraction and warpage.So Afterwards, the problem of being pointed out for mouldability analysis result, based on field mouthful test design method, with reference to Moldflow simulation analysis, grinds Study carefully the affecting laws of melt temperature, mold temperature, injection time, dwell pressure and dwell time to skeleton buckling deformation amount, And melt temperature, injection time, V/P switchings (% volumes), dwell pressure and dwell time are to clad cubical contraction Affecting laws, and obtain optimal combination of process parameters.
It is can be easily separated after moccasin injection with skeleton, form cracking, attractive in appearance and performance is influenceed, now to automobile environment-protection It is required that more and more higher, interior trim is also required to good environmental-protecting performance.
The content of the invention
The object of the invention is exactly that there is provided a kind of double-decker inside gadget injection moulding process in order to make up the defect of prior art.
The present invention is achieved by the following technical solutions：
A kind of double-decker inside gadget injection moulding process, step is：
（1）The carbon nano-fiber containing 3-4wt% in skeleton, ABS ebonites is made with ABS ebonite injection moldings；
（2）Mold cavity is made using skeleton as substrate, PPT flexible glues are heated and melted, are molded in mold cavity, by protecting Pressure, cooling, form one layer of Soft Roll coating on skeleton, form double-decker, produce.
4-5wt% ZnO doughnuts are added in the PPT flexible glues.
Carbon nano-fiber is handled with 4-5wt% silane coupler solution, added after drying.
ZnO doughnuts are handled with 4-5wt% silane coupler solution, added after drying.
The temperature of skeleton is kept for 100-120 DEG C when carrying out the injection of Soft Roll coating.
Relative dwell pressure is 60-70% when carrying out the injection of Soft Roll coating, and melt temperature is 185-200 DEG C, and injection time is 1-2s。
Secondary heat treatment is carried out after the completion of skeleton injection, first time heat treatment temperature is 130-140 DEG C, and the time is 8-9s, Second of heat treatment temperature is 100-110 DEG C, and the time is 10-13s
It is an advantage of the invention that：The present invention adds carbon nano-fiber formation skeleton with ABS ebonites, and intensity is high, good toughness, in skeleton The bond strength that upper injection is formed between one layer of PPT Soft Roll coating, two layers is high, is difficult division, and service life is long, in Soft Roll coating Middle addition ZnO doughnuts, the carbon nano-fiber improved in the intensity of clad, inoxidizability, with skeleton forms dual knot Structure, being capable of radiation proof, raising environmental-protecting performance.When carrying out the injection of Soft Roll coating, ABS skeletons keep certain high temperature so that double The shrinkage factor of Rotating fields is close, is not readily separated, and improves bond strength and aesthetic property.
