Abstract
A making method for micro-grain stereo-die assembly is mainly a hologram (optic grating) sheet with surfacial micro-grain made up by the laser hologram technique, the sheet is glued on a manual die, with which a colloidal stereo-die is first duplicated, and then conductive layer and electrocast layer are applied to the colloidal die body to make up a surface layer with concavo-convex micro-grain face, which can be applied to making a large amount of panels with facade of micro-grain surface.
Description
The present invention is a kind of making method of relevant trickle line three-dimensional mold, is the mat manual mould of the trickle lamina of tool, through a succession of copy job, and makes the also trickle line face of tool of three-dimensional mold top layer that duplicates the back.
To close on transparent lamp shade according to the size cutting of lampshade through the made grating plastic cement flat board of full-figure technique by at present general laser light fixture system of seeing, very light is bright brilliant when light is penetrated the diffraction radiance that just produce seven coloured silks when seeing through this grating lampshade by lamp body, but this kind method is very consuming time, or there is the dealer to produce (the plastic rubber ejaculate molding method of imitative CD disc) on the mould via the plane that the made grating metal sheet of laser full-figure technique (hereinafter to be referred as the laser metal sheet) fits in tradition, and the lampshade of the trickle line of ejaculation tool grating, but this method also can only be produced the lampshade on plane, when lampshade is then There is nothing one can do for other three-dimensional shapes, also there is the dealer surface segmentation of three-dimensional mold to be become the plane of various different shapeies and size at present, cut out successively and fitted behind the laser metal sheet on it, and the three-dimensional die that forms tool laser metal sheet is bestowed electroforming again and is duplicated, but this method is also unworkable, its shortcoming is: because laser metal sheet system is cliped and pasted on three-dimensional die by fritter, the joint on its adjacent two planes of microcosmic forms a breaking joint, this breaking joint will form current concentration (most advanced and sophisticated current potential) phenomenon and can't electrotyping forming when carrying out electroforming, this kind breaking joint is the difficult problem that present industry all can't overcome, except since this laser metal sheet system fit on the die, when under the high temperature electroforming solution, the applying power of its sticking work agent reduces, and electroforming solution also needs constantly to impact to die with inflating pump, thereby often take place that the laser metal sheet comes off and the situation of electroforming solution is polluted in the agent of sticking work, even supposing the problems referred to above all overcomes, and the dendritic burr at breaking joint place also are difficult to finishing, so do not see as yet that so far the one-body molded light fixture of the three-dimensional microgroove of any tool is arranged.
Therefore, the present invention's main purpose, promptly at the shortage of the designed mould of present industry, provide a cover to duplicate the mode of operation of three-dimensional mould continuously, trickle lamina is replicated on the three-dimensional mold practically, and can produces Multi-color lampshade in large quantities, in addition, when duplicating three-dimensional mold, more can omit unnecessary dressing operation by the present invention's production process, make the making of three-dimensional mold do not finished rapidly the person.
According to a kind of trickle line three-dimensional mold making method of the present invention, comprising:
One prefabricated die body, the laser metal sheet of the concavo-convex trickle line of its surperficial sticker top layer tool is inferiorly annotated in the surface of prefabricated die body with elastic colloid liquid, after making it to be shaped to another and duplicating rubber moulding, form electricity layer together earlier in the top layer of rubber moulding, give electroforming again and form the three-dimensional mold of the trickle line of a surperficial tool.
Now the explanation of conjunction with figs., it is as follows to enumerate one of the present invention preferred embodiment:
Fig. 1 is the synoptic diagram of the manual mould gummed of expression laser metal sheet.
Fig. 2 system is shown in the synoptic diagram of manual mould copying surface one glue master mold.
Fig. 3 is tied to form the glue master mold sectional view behind the type.
Fig. 4 is the synoptic diagram that the glue master mold imposes electrolytic coating.
Fig. 5 is that the glue master mold imposes the synoptic diagram that electroformed layer duplicates three-dimensional punching block.
Fig. 6 is the synoptic diagram of three-dimensional punching block after the finishing electroforming.
The synoptic diagram that three-dimensional punching block after the moulding cooperates another three-dimensional mould duplicates in Fig. 7 system.
Fig. 8 system is according to the laser Multi-color lampshade synoptic diagram of the invention process.
Please refer to Fig. 1, the present invention at first is the sample attitude by lampshade, make manual mould 10, then press the geometric shape of model surface, cut out laser metal sheet 20 with surperficial trickle line 211, and in regular turn sticker in manual mould surface, and because the thickness of laser metal sheet is atomic, and can reserve thickness prior to manual mould surface in advance, so manual mould behind the sticker laser metal sheet, do not take off the sample attitude of original lampshade, then again by as shown in Figure 2, manual mould is inserted in the model cover 30, and inject and irritate special-purpose silica gel of mould or epoxy glue class, in order to duplicate a glue master mold 40, back to be formed withdrawing pattern, have the generation of burr (too much silica gel liquid flows and injects on the seam that two laser metal sheets join) even if glue master mold inside is still inevasible when moulding, but only need this moment to use little cutter can be easily the burr of master mold inside to be excised, and the three-dimensional master mold 40 of the no breaking joint in a perfect surface, and can not injure the upper layer of glue master mold inwall, and since within the glue master mold wall system with tire out that the laser metal sheet is corresponding does that the casting of applying glue is dies, therefore the glue master mold inwall that duplicates the back will form 211 layers of the trickle lines (as shown in Figure 3) of one deck and the opposite groove of the trickle line of laser metal sheet surface, inferior ginseng such as Fig. 4,5,6, edge of the present invention will be repaired the glue master mold that improves the back and execute a conductive layer 50(earlier and be generally silver, can vacuum evaporation, vacuum splashing and plating or spray silver, spray nickel, spray copper method for it), then electroforming one bed thickness nickel or copper 60 again, and on nickel dam, pour zinc liquid 70 into, can finish one pair of production mould 80(male model), treat with the dorsal part equating of mould whole after (as shown in Figure 7), just can get the production mould 80(male model that a surperficial tool improves trickle lamina), in addition owing to the glue master mold 40 of the present invention in order to the moulding production mould, have and be easy to peel off, not easily damaged characteristic, therefore can over and over again remake and overpay the production mould by this glue master mold, to improve turnout, and, peels off by the present invention's glue master mold because having easily, be difficult for hindering the characteristic that cooperates male model, so also can be over and over again silica gel liquid etc. be injected the surface of manual mould 10, glue master mold 40 so that production is overpaied also belongs to play the same tune on different musical instruments wonderful.At last, as shown in Figure 8, the present invention will use this surface to see that the production mould of trickle line cooperates general steel master mold, frame is used for ejection formation to produce lampshade on shaper, and the lampshade 90 after the moulding, side will be in response to the trickle line in the top layer of male model within its lampshade, and corresponding 211 layers of the corresponding trickle lines that produce, at this moment, if with light source projects on lampshade the time, but lampshade just nationality gives diffraction by the trickle lamina of the various different angles in its top layer with light and goes out the very beautiful bright brilliance of dazzling, and promptly is commonly called as so-called ground Multi-color lampshade.And above series is lifted with a manual mould sticker laser metal sheet, and mat glue master mold forms the specific embodiment of the trickle line production mould of a surperficial tool in the electroforming mode, only the present invention has more than the enforcement that is confined to lampshade, and die surface must have trickle lamina person such as, all is that the present invention's enforcement is derived.
