Abstract
The invention discloses a method for manufacturing a vehicle sign by an in-mold decoration technology. The method is characterized in that the method comprises the following steps of: thermally-pressing and shaping a compound film to a film with a thickness of 0.45-0.55mm and a certain shape by a vacuum thermally-pressing machine; then putting the film on a three-dimensional cutting machine and cutting the edge of the film so as to remove spare parts and burrs; then forming a plastic panel with a thickness of 2.0-2.5mm by in-mold injection molding; and finally, assembling the plastic panel with a plastic base through a pneumatic pressing machine to obtain a shaped vehicle sign. The method has the advantages of higher surface wear resistance, good resistance to color change, high rate of finished products, energy conservation, environment protection, simple technical processes and easiness in operation.
Description
Technical field
The present invention relates to a kind of preparation method of vehicle label, especially relate to a kind of method of utilizing decoration technique inside mold to make vehicle label.
Background technology
The preparation method of existing vehicle label generally comprises following steps: after aluminium sheet being injected the blank of vehicle label; Sprayed protection lacquer is put into and is watered the groove that injection molding and vehicle label shape match, and in mould, pours into a mould vehicle label bottom surface material; The membrane moulding gets final product; The vehicle label that utilizes this method making paints destructible, thereby causes aluminium material to be prone to oxidation in assembling and transportation; The marginal portion of vehicle label since paint spraying less than or quantity for spray less, also be prone to cause the aluminium material oxidation, simultaneously there is texture in working of plastics product itself, and is uneven, be easy to generate potential corrosion, thereby cause vehicle label, blackout, variable color, surface are not wear-resisting.
In-mold decoration (IMD, In-Mold Decoration) is exactly that the decoration sheet that will print forming is put into injection mould, then plastics is injected at the back side of formed sheet, makes plastics and decoration sheet be bonded into one, then the technology of curing molding.This technology can not only obtain required product shape and size, also can give product outer surface certain physical, chemistry, electric and feel decorative engineering effect.The person of being designed is applied in the different product of every profession and trade more and more, still, also decoration technique inside mold is not applied to the correlative study report that vehicle label is made both at home and abroad at present.
Summary of the invention
Technical problem to be solved by this invention provide a kind of surface abrasion resistance, not easy to change, yield rate is high, energy-conserving and environment-protective, technical process simply utilizes decoration technique inside mold to make the method for vehicle label.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of method of utilizing decoration technique inside mold to make vehicle label may further comprise the steps:
(1) diaphragm vacuum forming: with transparent or to have poly terephthalic acid class and polymethyl methacrylate (PET/PMMA) composite membrane of color hot-forming through the vacuum hotpressing machine be the diaphragm with definite shape of 0.45～0.55mm for thickness;
(2) side cut is pruned: the diaphragm of step (1) forming is placed the pruning of cutting edge on the three-dimensional cutting machine, remove redundance and burr;
(3) in-mould injection: the diaphragm that step (2) is cut accurately is positioned over and carries out in-mould injection in the injection machine mould; Under vacuum protection, membrane surface is poured into a mould high fluidity propylene nitrile-styrene-butadiene copolymer (ABS) material; Injection temperature is controlled to be 230～240 ℃; Injection pressure is controlled to be 70～75 MPa, and injection moulding speed is controlled to be 30～40cm
3/ s, mold temperature is controlled to be 75～85 ℃ during injection moulding, forms the plastic front board that thickness is 2.0～2.5mm at last;
(4) base injection moulding: will electroplate level acrylonitrile-styrene-butadiene copolymer (ABS) injected plastics material and carry out in-mould injection formation plastic feet;
(5) assembling moulding: plastic front board and plastic feet that step (3) is obtained assemble through the pneumatic clamping machine, promptly obtain the vehicle label of moulding.
Injection machine mould mould described in the step (3) advances the cast gate design in product edge, and gate form is cold runner and sub marine gate charging.
Compared with prior art; The invention has the advantages that: the present invention discloses a kind of method of utilizing decoration technique inside mold to make vehicle label first; With diaphragm vacuum forming, cut edge pruning, in-mould injection; At last plastic front board and plastic feet assembling are obtained vehicle label, vehicle label and existing vacuum coating and coating process that this method is made are owing to adopt the PET/PMMA composite membrane; Make plastic front board have better wear resistance, the thickness of formation is the diaphragm of 0.5mm neither too hard, nor too soft (nature is placed the shape that remains unchanged); Owing to saved oil spout lacquer step, under vacuum state, plastic front board and plastic feet are directly assembled, make vehicle label color that the present invention makes homogeneous and not easy to change more, and environmental protection more; Because manufacturing process adopts self-reacting device, make yield rate high, technical process is simple to operation simultaneously, so the preparation method of vehicle label of the present invention makes that its surface abrasion resistance is higher, not easy to change, yield rate is high, energy-conserving and environment-protective and technical process are simple to operation.
