Abstract
The invention provides a manufacturing method of a double-color shell structure. The double-color shell structure comprises a first layer molded from one color, a first film molded once, a second layer molded for the second time, and a second film molded for the second time, wherein the first film is between the first layer and the second layer; the second film is arranged at the other side of the second layer opposite to the first film; the first layer and the second layer are molded by injection; the first film and the second film can respectively adopt in molding film (In Molding Film, IMF) and in molding roller (In Molding Roller, IMR) to coat patterns on the film to the first layer and the second layer, or the first film or the second film does not adopt an in-mold decoration (In-Mold Decoration, IMD) technology. According to the invention, a double-color shell can be obtained, and the surface pattern is not easily scratched.
Description
Technical field
The present invention relates to a kind of shell structure, particularly a kind of manufacturing approach that adopts the double-color shell structure of interior applying of mould and decoration technique inside mold.
Background technology
In-mold decoration (In-Mold Decoration; IMD) technology is the international at present surface decoration technique that is in fashion, its transparent membrane that hardens on the surface, and the centre is a printing pattern layer; The back side is injection molded layers; Printing ink can make product prevent that the surface from being scratched and rub resistance, and can keep the distinctness of color to be difficult for fading for a long time in the centre.
In the decoration technique inside mold again with the decoration technique inside mold of dual-color forming the most complicated (i.e. four look forming techniques); Common way is that mould is designed to double-color mold; Utilization decoration technique inside mold one-time formed the time, the external coating at goods after the post forming prints desired pattern and label.Influence the goods cycle owing to also will pass through application printing, and pattern and the label of application after printing scratched easily and also do not had wearability, can't be obtained the outward appearance product of high-quality high request.Double-colored decoration technique inside mold just can well reach this requirement; Yet this technology owing to fit in the mould (In Molding Film, IMF) with mould in ripple seal (In Molding Roller, IMR) diaphragm all need be opened corresponding mould and makes; So the die products cycle is long, and cost is higher.
Therefore, the present invention promptly proposes a kind of manufacturing approach of double-color shell structure, and to overcome above-mentioned described these problems, the concrete framework and the specific embodiment thereof will be specified in down
Summary of the invention
Main purpose of the present invention is in the manufacturing approach that a kind of double-color shell structure is provided; It forms the ground floor and the second layer respectively with twice ejection formation; Between the ground floor and the second layer, more be provided with a first film; And be provided with second film at the opposite side of the second layer, make product have two sides different colours or pattern, and the first film and second film adopt in the mould seal (IMR) or do not adopt in-mold decoration (IMD) technology of fitting (IMF), ripple in the mould respectively.
Another object of the present invention is in the manufacturing approach that a kind of double-color shell structure is provided, and its decorating film surface that can prevent product is scratched, and promotes wear-resisting wiping property, and can keep the distinctness of color to be difficult for fading for a long time, can also increase the cubic appearance of figure.
A purpose more of the present invention is in the manufacturing approach that a kind of double-color shell structure is provided, and it is fully showed the pattern of the first film and second film, and product appearance is exquisite, and is easy to fully-automatic production.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
A kind of manufacturing approach of double-color shell structure is characterized in that, comprises the following steps:
A the first film is positioned on one first mother module core, relies at least one suction hole to vacuumize so that this first film absorption is close on this first mother module core;

This first male model benevolence is rotated to a post forming position, and utilize a pressing mold pressure ring that one second film is pressed in this second mother module core; And
Behind this first male model benevolence and this second mother module core matched moulds, inject a kind of material to form a second layer, the printing ink on this second film is transferred on the surface of this second layer, accomplishes two looks.
Wherein: this first mother module core is a moulding mother module core of the same colour, and this first male model benevolence is a moulding male model benevolence of the same colour.
Wherein: this second mother module core is one two a look moulding mother module core.
Wherein: also comprise at least one positioning hole collumn on this first mother module core, this first film is aimed at this positioning hole collumn and is placed.
Wherein: this second film is adsorbed in this second mother module core with the mode of vacuumizing.
Wherein: this ground floor is a forming plastic cement spare of the same colour, and this second layer is two look moulding materials.
Wherein: when this first male model benevolence rotated to this post forming position, this pressing mold pressure ring of this two looks shaping position was opened.
Wherein: this second film is positioned earlier on this second mother module core, utilizes this pressing mold pressure ring that this second film is pressed in this second mother module core again.
Wherein: this ground floor and this second layer are formed at the both sides of this first film respectively.
Wherein: this ground floor is a forming plastic cement layer of the same colour, when moulding of the same colour, produces.
Wherein: this second layer is one two a look forming plastic cement layer, and it is a clarity plastic layer or an opaque plastic layer, when two look moulding, produces.
Wherein: this first film is to adopt the technology of fitting in ripple in the mould seal or the mould that pattern is coated with to install to this ground floor.
Wherein: this second film is to adopt the technology of fitting in ripple in the mould seal or the mould that pattern is coated with to install to this second layer.
Wherein: this first film and this second film are to adopt the different surface decoration technique that pattern is coated with to install on this ground floor and this second layer.
Wherein: this first film or this second film do not use decoration technique inside mold when moulding of the same colour or two look moulding.
Wherein: more be provided with a printed circuit on this first film, be provided with an external contact of this printed circuit in this ground floor.
Compared with prior art; The beneficial effect that the present invention has is: the present invention provides a kind of manufacturing approach of double-color shell structure; It forms the ground floor and the second layer respectively with twice ejection formation, between the ground floor and the second layer, more is provided with the first film, and is provided with second film at the second layer with respect to the opposite side of the first film; Make product have two sides different colours or pattern; And the first film and second film adopt respectively and ripple seal (IMR) in the mould in applying (IMF), the mould or do not adopt in-mold decoration (IMD) technology, and it is bright-coloured colour-fast that pattern keeps, but and automated production.
