Background technology:
In in-mold decoration processes, generally adopt following processing step at present: the one side at transparent plastic film (as polycarbonate film, pet film) generates pattern and character decorative cover oil lamella with the mode of printing.Its mode of printing can adopt serigraphy as the case may be, film printing and digital printing etc. (can be coated with silane coupling agent in case of necessity to strengthen the adhesive strength of printing ink on film).Again with mould carry out three-dimensionally shaped through after cutting film.Film after the moulding is put into special injection mold locatees: according to different film shape sizes, can select Electrostatic Absorption method location for use, or select the natural positioning mode by the frame for movement key element for use, or select the keeper method that adds for use.Carry out mold-closing injection after finish the location in mould, divide mould to take out moulding, promptly obtain the working of plastics of incrustation.
In-mold decoration processes is compared with traditional decoration technologies such as the surface lacquer of general moulding, printing, pad pastings has more advantage, but also has weak point in actual process, and subject matter is:
1. the plastic film thickness of selecting for use in the ordinary course of things is about 0.1-0.3mm, and is relatively poor through its rigidity of moulding plastics film after three-dimensionally shaped, and especially (as size more than 20cm) its rigidity is poorer when large scale, and is harsh more to the requirement of location.The hot melting plastic that also can be subjected to HTHP in injection moulding process is thereafter impacted, and very easily is out of shape and folds.Head it off generally is that the form film of putting into molding mold cavity is carried out complicated location and clamping at present, promptly needs to increase on the basis of ordinary injection die complicated location and clamping device.And this its manufacturing cost of in-mold decoration particular manufacturing craft is far above common die.Based on above reason, present in-mold decoration processes also is confined in the incrustation utilization scope of reduced size product basically, and as mobile phone, the shell of products such as PDA is decorated.Decorate for the shell of big-and-middle-sized product, as television set, the product of large-sizes such as computer monitor, if adopt present in-mold decoration processes will increase Mould Machining difficulty and cost greatly, and production efficiency of products and yield rate are extremely low.So, still do not have and adopt this technology on a large scale up at present.
2. when injection mo(u)lding, the hot melting plastic of HTHP directly can be washed away the printing ink layer at the plastic sheeting back side, causes the ruined phenomenon of ink lay easily, and the ink lay that especially is positioned at the cast gate place is the easiest of erosion damage.Head it off mainly contains following several solution at present:
A. injection mold is improved.Described a kind of scheme that slide block is set at mould gate among the patent No. 0104330.X and prevented that ink lay is by erosion damage.This method need be made particular manufacturing craft, and its cost all is higher than ordinary injection die, and all will strengthen for the mould design difficulty and the manufacturing cost of the medium-and-large-sized moulding of many cast gates.
B. bonding one deck thermoplastic film protective layer on printing ink layer.Described in the number of patent application 200410060004.5 and adopted bonding layer of plastic film protective layer on ink lay, can play preventing that printing ink is by erosion damage.But the plastic sheeting protective layer that this method adopts is because its rigidity deficiency still needs to carry out special location and clamping in injection mold.And in injection moulding process, promptly also be out of shape because of the influence of high temperature easily, promptly exist as problem 1 described deficiency.
Summary of the invention:
Inner-mould ornamental plastic member in order to provide a kind of good rigidly, available ordinary injection die that production cost is low to finish is provided.Another object of the present invention is in order to provide a kind of speed of production fast, and the yield rate height is particularly useful for the preparation method of the inner-mould ornamental plastic member that can finish that the shell of large scale product decorates in ordinary injection die.

Above-mentioned transparent plastic film thickness is 0.05～1mm.
Above-mentioned decoration flexible layer adopts printing thin film or cloth or leather to make.
The preparation method step of the inner-mould ornamental plastic member that the present invention can finish with ordinary injection die is as follows:
A selects materials: select required decorative flexible materials and sheet metal for use;
B makes it to become the sheet composite bed that good rigidly is easy to three-dimensionally shaped processing again with decorative flexible materials and sheet metal pressing;
C carries out three-dimensionally shaped through cutting the back with mould composite bed;
D puts into the ordinary injection die injection moulding with three-dimensionally shaped composite bed, just injects the decorative plastic part of plastic substrate.
Decorative flexible materials printed patterns and/or text decoration layer and form on transparent plastic film in the above-mentioned method.
In the above-mentioned method before compound on the one side at least of sheet metal coating have a resistant to elevated temperatures adhesive phase, then with decorative flexible materials by adhesive phase on the sheet metal and sheet metal pressing.
Adopted metal level to increase the rigidity of flexible decorative layer in the decorative plastic part of the present invention, so good rigidly.Because available ordinary injection die is finished, so production cost is low.Decorative plastic part of the present invention can be done very greatly, all can realize about 1 meter as size.
