Abstract
Disclosed is preparation technique for a decoration piece in a die, comprising the following steps: firstly, a vignette is printed on the surface of a transparent substrate material with ink; secondly, the printed film is treated under high pressure to be modeled into the needed shape and the redundant margin part is cut off. The high pressure treatment is done with a high-pressure molding machine and the technique parameters are that the upper and the lower heating temperature are between 280 DEG C and 380 DEG C; the temperature of the hot air is between 250 DEG C and 350 DEG C; the preheating temperature of the die is between 60 DEG C and 120 DEG C; the die closing time is from 6 to 20 seconds; the molding time is from 7 to 20 seconds; the exhausting time is from 3 to 8 seconds; the die closing speed is from 50 to 100 percent and the die opening speed is from 50 to 100 percent; thirdly, the printed film in a certain shape is put into the cavity of the die and thermoplastic resin is injected to make the film into a product; the parameters of the molding technique are subject to the thermoplastic resin. The invention is the technique of veneering at the same time with injection molding; the product and the decorative printed material are compounded into a whole and solid molded product can be printed with a decorative vignette, making the product having both functional effect and decorative effect.
Description
Technical field
The present invention relates to the preparation technology of used in-mould ornament such as manufacturing that the surface has ornamental resin (plastics) formed products.Particularly, the present invention relates to be suitable for to make the shell of products such as computer, camera, mobile phone and Vehicular instrument panel and vehicle preparation technology with the in-mould ornament of the resin forming product of taillight indicator etc.
Background technology
Make computer, camera, mobile phone, combined instrument for vehicle shell, Air-Conditioning Control Panel, home electric control panel, vehicle taillight indicator etc. at present.Its incrustation all is after formed product as pattern, literal, numeral etc., and the method that adopts spraying, water transfer printing etc. is with relevant pattern, literal, digital printed to finished product.Such method exists following technical problem: 1, the printed layers and the substrate combinating strength of pattern, literal, numeral are not enough, and service time one is long, comes off easily, has influence on the aesthetics of product.2, the organic solvent of spraying use has certain toxicity, has environmental pollution problems.3, because spraying method is subjected to technical limitations, on the level of color and color, all there are certain limitation and deficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide the preparation technology of used in-mould ornament such as manufacturing that a kind of surface has ornamental plastic foil formed products.The thermoplastic film that this preparation technology directly will be printed on pattern, literal, numeral is compounded on the matrix.Has the advantage that the finished product aesthetic feeling is good, do not use solvent, non-environmental-pollution.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
The preparation technology of in-mould ornament comprises the steps:
1, on transparent substrate surface, adopts the ink printing decorative pattern;
2, to carry out high-pressure forming be needed shape to the film that will finish this printing, and cut unnecessary rim charge; Wherein the HDVF high-pressure forming machine is adopted in high-pressure forming, its technological parameter is that upper and lower heating-up temperature is 280 ℃～380 ℃, hot air temperature is 250 ℃～350 ℃, the preheat temperature of mould is 60 ℃～120 ℃, the matched moulds time is 6s～20s, and molding time is 7s～20s, and evacuation time is 3s～8s, matched moulds speed 50%-100%, die sinking speed 50%-100%;
3, will have finishing of shape the film of printing be contained in the mold cavity, inject thermoplastic resin and form goods, injection technological parameter is decided according to selected thermoplastic resin.
The present invention puts into injection mould with the decoration sheet that prints forming, then resin injection is bonded into the technology of one curing molding in the mould with sheet material.
Adopt the finished product of preparation method of the present invention preparation, its surface is the UV hardened layer, is the plastic foil that is printed on ink logo below, is exactly the plastic cement matrix below again.The advantage of this technology is a cure process for the surface, the hardness height, and high temperature resistant condition is better.Because printing ink is clipped in the middle, can makes product prevent that surperficial being scraped from undermining wear-resisting wiping, and can keep the distinctness of color to be difficult for fading for a long time.
The present invention carries out the technology that mold insert bands simultaneously injection molding, and product is to be laminated with and to become one with the decoration material of undertaking the printing of, and makes product reach ornamental and functional effect.
The present invention has following advantage relative to existing technologies:
1, product stability is good, makes product produce uniformity and standardized correct chromatography.
2, durability of product is good, and the protection of the film by specially treated can provide the better surface abrasion resistance of product, scratch resistance damage and chemically-resistant characteristic.
3, can carry out the design of 3D complicated shape, the extensibility that applied film is good can be reached required product complexity and appearance design requirement smoothly.Stereo shaping can increase the free degree of design.
4, diversified style can be created metal according to customer demand and electroplate look or natural material look special patterns.
5, technical process is simplified, and via the technology of single injection-molded, moulding and decoration is reached simultaneously, can effectively reduce cost and man-hour, and stable production can be provided.Only need a mold in the production, need offer many molds, reduce system cost and inventory cost unlike other technology.
6, adopt mold insert injection moulding processing method can satisfy all pattern requirements, pattern and colour planning can change at any time, and need not change relevant mould.
7, window causes translucent effect after high transparency and good printing ink are arranged.
8, concavo-convex evenly, the good hand touch of function button, long service life.
9, superficial makings is even, and composite molding reaches seamless effect, and is dustproof, moisture resistance is good.
