Abstract

The present invention discloses a method of forming a small embossed pattern on the surface of a hard object. A mould which is provided with a mould cavity in a certain shape is machined and manufactured at first. A layer of paster is arranged in an area where the embossed pattern needs to be formed in the mould cavity. The plaster is carved, machined and cut into a certain pattern by using laser; the plaster outside the pattern is removed, and etching machining is carried out; at last, the remanent plaster is torn so that a small pattern which is not etched is generated in the mould cavity. The mould is machined by injection forming in order to manufacture a hard object with a small embossed pattern. The visual sensing and observing effect of the product can be increased.

Description

The method of forming small pattern on surface of hard object

Technical field

The present invention relates to the figure line processing method on a kind of hard thing surface, especially relate to a kind of method of producing small embossed pattern on hard thing surface.

Background technology

Along with the raising of people's quality of the life, to the also raising relatively of requirement of material quality, for texture that improves product and the desire to buy that stimulates consumer, the variation that can pursue at aspects such as profile, colors usually.As be widely used in fastener in the daily living articles such as clothing, knapsack, at employed fastener on the market, its form is of a great variety too numerous to enumerate, but all only changes on the decorative pattern of profile, color and texture, there is no outstanding part at present.Normally handle through some frosteds on the surface of products such as computer monitor framework, keyboard and Communication Equipment and for example, makes the surface that certain roughness be arranged, and visual effect is more single, does not also have texture.

Therefore how further hard thing being beautified, increase the effect on its visual sensory, use the texture that promotes article, to be applied on the Related product, increase the surcharge of this product, is the demand that has on its market.

Summary of the invention

Main purpose of the present invention is to provide a kind of method in forming small pattern on surface of hard object, improves the visual effect on hard thing surface.

For reaching above-mentioned purpose, the method for a kind of forming small pattern on surface of hard object provided by the invention, it may further comprise the steps:

A, Mould Machining: on template, produce die cavity with required surface treated product shape;

Paster in b, the die cavity: the surface portion that processing is handled to needs in die cavity sticks a layered paper;

C, laser cutting go out special pattern: utilize laser engraving processing, go out figure in the whole surface engraving of paster, alignment is arranged between each figure;

D, rejecting paster edge: will not have the paster edge part of engraving pattern to reject, and keep the paster that is carved with visuals;

E, carry out texture processing: all gap portions between the figure are etched into cloudy surface;

F, choose the residue paster: the paster in the die cavity is removed, in the die cavity of mould, form the pattern of small bright the pattern arrangement that is not subjected to texture;

G, inject machine-shaping: utilize Jet forming machine to produce hard thing on the mould of finishing, the small embossed pattern of hard thing surface tool.

Among the described step b height fall slight plane or cambered surface are processed the part of handling as one, stick a layered paper on each surface that need process the processing section.

The figure of being carved among the described step c can be the geometry that circle, triangle, quadrangle or other polygon etc. do not limit.

Laser Processing among the described step c, according to the machined surface of differing heights, the setting laser processing head degree of depth, blockette is processed.

Texture processing among the described step e, its etch depth is 0.01～0.5mm.

Preparation method disclosed by the invention is simple, in process, can in die cavity, produce micro pattern by laser engraving process technology, applying overlay film and texture processing, make the hard thing surface that makes have the visual effect of embossed pattern, improved the texture of product, increase the surcharge of product, thereby stimulated consumer consumption.This method can be widely applied in the surface treatment of various hard produce product.

The specific embodiment

Shown in Figure 1 is that the present invention is the block flow diagram of preparation method, and shown in Fig. 2～6, the inventive method is at specific embodiment of fastener surface-treated, and its making step is as follows:

A, Mould Machining: at first in Mold Making, mold template 10, impose conventional meanses such as miller and discharge processing by machine-tool, produce the die cavity 11 (as Fig. 2) of light (mirror) face with fastener contour shape;

B, die cavity add and stick paster: in die cavity 11, to the part that the slight plane of height fall or cambered surface are handled as a processing, stick a layered paper 20 (as Fig. 3) on the surface of processing processing section;

C, laser cutting go out special pattern: utilize the laser engraving processing technology, carve out specific figure 21 on the whole surface of the paster 20 in die cavity 11, this figure 21 can be the geometry that circle, triangle, quadrangle or other polygon etc. do not limit, and each figure intersection alignment of carving out is arranged in the decorative pattern (as Fig. 3) of latticed decorative pattern or other regular arrangement.If a plurality of surfaces that need processing to handle are arranged, then can be according to the differing heights of machined surface, the setting laser processing head degree of depth, blockette is processed.

D, choose edge part not: the paster edge part that does not have engraving pattern beyond the figure 21 22 is rejected, and the paster part that keeps figure 21 is in die cavity 11 (as Fig. 4);

E, carry out texture (discharge process) processing: carry out texture processing in die cavity 11, it is planar 12 that all gap portions between the figure 21 are etched the decorative pattern mist formation, and this etch depth is about 0.01～0.5mm (as Fig. 4);

F, choose the residue paster: the 21 part pasters of the figure in the die cavity 11 are removed, and formation is not subjected to the pattern 13 (as Fig. 5) of small bright pattern arrangement of texture in the die cavity 11 of mould.

G, carry out plastics injections machine-shaping: utilize Jet forming machine to produce the fastener 30 that the surface has small embossed pattern 31 on the mould of finishing 10.

By said method, can create the fastener of providing the visual sensory effect, with the texture of increase fastener, and this fastener can be applied on the Related product, to increase the surcharge of this product.If on template, make the depression that slide fastener is decorated pulling-on piece,, promptly can be made into the slide fastener decoration pulling-on piece that the surface has small embossed pattern 31 by the inventive method.Equally, above-mentioned processing method of the present invention also can be applicable to such as on the products such as computer monitor framework, keyboard and Communication Equipment, has the product that small embossed pattern is rich in texture thereby make the surface.

The above only is preferred embodiment of the present invention, can not limit scope of the invention process with this; Allly change and modify, still belong in the scope that patent of the present invention contains according to the present patent application claim and description of the invention simple equivalent that content is done.
