Background technology

Consult shown in Figure 1, be the three-dimensional part sectioned view of the housing of commonly using, the shaping surface of this housing 1 has lines 2, these lines 2 are carved good corresponding lines in advance in the die cavity of plastic injection forming mold, so when plastic cement ejaculation material was fed in the die cavity, lines 2 just was formed on the surface of finished product housing 1, so if ten kinds of different lines, will prepare ten groups of moulds at least, the value of each group mould is all in hundreds thousand of units, and the cost cost of preparing many group moulds is quite surprising.

Only, its above-mentioned housing molding surface pattern or color of commonly using still has following disappearance:

One, the die cavity inside of mould is not that all lines or colors all can carve, and some lines can't carve at all, so still have its restriction place by the inner rag of die cavity road.

Two, the inner texturing line of die cavity is quite time-consuming, and price is also quite expensive, it is just expensive to add the cost of mold own, so there are not a considerable amount of products, be to divide the huge expenditure of mould, but the quantitative requirement of single kind of lines housing just can not be a lot, make that housing all can only be made shiny surface now, and without any lines.

Three, the color change of commonly using after the mould housing moulding must being taken out, presents various different brightness colors with spraying method.

Be with, at the existing problem points of above-mentioned conventional construction, how to develop a kind of innovation structure that has more desirable practicality, the ardent hope of real consumer institute also is that relevant dealer must make great efforts target and the direction that research and development break through.

In view of this, the creator this in manufacturing development and the design experiences of being engaged in Related product for many years, at above-mentioned target, in detail after design and the scrupulous assessment, eventually the utility model of a true tool practicality.

Summary of the invention

The utility model purpose is, the PU putamina structure of multiple lines of a kind of tool and color change is provided, and to overcome the defective of above-mentioned traditional structure, its surface of shell can process multiple lines and color change easily, suitable a large amount of production.

Technical solutions of the utility model: the PU putamina structure of multiple lines of a kind of tool and color change, it is characterized in that, include:

The plastic material layer of one ejection formation;

The one PU putamina of making by PU diaphragm thermoplastic mold pressing with decorative pattern or color; This PU putamina layer is positioned at the plastic material laminar surface, and combines with described plastic material layer.

Wherein, this plastic material layer is made by propylene-butadiene-styrene polymer (ABS).

Wherein, (Polyurethane PU) makes this plastic material layer by polyurethanes.

Wherein, (Polycarbonate PC) makes this plastic material layer by Merlon.

The utility model beneficial effect:

One, housing of the present utility model also can be produced single kind of decorative pattern demand after a little while, so can break the conventional thought of standard figure colour, allow the decorative pattern or the color of electronic product (as mobile phone etc.) housing, has personalized uniqueness, and can allow decorative pattern produce the effect of on-slip line, or warn honeycomb face effect.

Two, hierarchical structure of the present utility model is different from the ejection formation structure of prior art, and in the hierarchical structure of the present utility model, layer structure more comprises the decorative pattern and the color of surface structure, this decorative pattern and color are just molded when still being the PU diaphragm at layer structure, follow-up thermoplastic pattern processing and injection shaping die processing, then all be to process at the housing external form, need not be again to decorative pattern and color processing, so the outer surface decorative pattern and the color of shell layer level structure of making and layer structure are different from prior art.

Therefore, hierarchical structure of the present utility model is different from the structure that known ejection formation is made, and relatively the housing of the utility model and known techniques has on the easness of decorative pattern and color, the utility model is more prone to, even and if quantity can change the housing of multicolour or decorative pattern less also quite easily in reaching with a kind of type.And, broken through the prior art bottleneck, be able to this shell skin produce located by prior art decorative pattern and the color that can't make.

The technology that relevant the utility model adopted, means and effect thereof after lifting a preferred embodiment now and cooperating graphic being described in more detail in, are believed the above-mentioned purpose of the utility model, structure and feature, when can by one deeply and concrete understanding.

Embodiment

Consult shown in Figure 2ly, the utility model provides the PU putamina structure of multiple lines of a kind of tool and color change,

This shell structure comprises:

One plastic material layer 10, (Polycarbonate PC) waits plastic material to make to the material of this plastic material layer 10 by propylene-butadiene-styrene polymer (ABS), Merlon;

One PU putamina layer 20, this PU putamina 20 is when still being the PU diaphragm, with regard to specific decorative pattern or the color of moulding, so PU putamina layer 20 surface of finished product housing also have decorative pattern or color.

Described PU putamina layer 20 is to be molded as the PU putamina by the PU diaphragm prior to the thermoplastics type, the PU putamina is placed the molded housing surface location of ejection shaping die die cavity again, promptly gets a housing 30 with PU putamina layer 20 through ejection formation.

Consult shown in Figure 3, for identical patterns but the contrast schematic diagram of two kinds of PU diaphragms of different color effect, same a kind of decorative pattern of PU diaphragm also can be made different color representation, as shown be similarly cancellate decorative pattern 41, the surface of a kind of PU diaphragm 40a just produces the performance near black (expression of adding some points), the surface of another kind of PU diaphragm 40b just produces the performance near blue (blank expression), and be provided with most same direction twills by each grid inside, the waling difference of contiguous grid, can produce different light and shade shadows, make and visually produce the stereoscopic depth effect.Hence one can see that, just with a kind of decorative pattern, and the application that just has different colours to change.

Consult the effect comparison with different tones shown in Figure 4, atomizing processing 51 also can be done on the surface of blue (representing than multiple spot) in the surface of PU diaphragm 50a, feasible surface is comparatively coarse, dim aesthetic feeling is also arranged, on the other hand, 51 surfaces are handled in same atomizing, and the performance of different colours is also arranged, and performance that also can light blue (less point is represented) as the surface of PU diaphragm 50b is exactly another aspect.

Consult identical decorative pattern shown in Figure 5 but the effect of different tones, the surface of PU diaphragm 52 also can present the decorative pattern of dermatine, and is similarly the decorative pattern of dermatine, and its color also can make dark colour 53a or light colour 53b changes, and makes it show more horn of plenty.
