Abstract
The invention discloses a process method for directly forming a mold. The method comprises the following steps of (1) mold building: a computer technology is used for building a three-dimensional stereo model of the mold; (2) data processing: the three-dimensional stereo model of the mold is subjected to layering processing by special software, and a series of cross section shapes are obtained; (3) powder paving and sintering: raw material powder is sintered through laser beam scanning according to the obtained cross section shapes in the second step, the cross section of each layer is obtained through curing, a work table downwards moves for one layer after the sintering completion of one layer of cross section, a new layer of cross section is obtained through continuous sintering, and the cross section layers are laminated layer by layer until the whole primary mold is completed; (4) post processing: the surface of a primary mold manufactured in the step (3) is ground and polished, then, cleaning is carried out, in addition, the integral curing is carried out, and a finished product mold is formed. Through adopting the mold, the process method can adapt to the manufacturing of molds in various complicated shapes, and a die core and a die cavity of the mold are precisely manufactured.
Description
Technical field
The present invention relates to mould molding technical field, particularly relate to a kind of process of mould straight forming.
Background technology
Mould be in industrial production in order to injection moulding, blowing, extrude, cast, various mould and instrument that shaping, smelting, punching press, the method such as stretching obtain required product.In brief, mould is used to the instrument of formed article.The height of Tool and Die Technology level is the important symbol weighing manufacturing industry level height.Traditional die processing method, the manufacturing cycle is longer, and cost is high, is difficult to the change rapidly adapting to market.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of process of mould straight forming, can adapt to the manufacture of the mould of various complicated shape, produces core and the die cavity of mould accurately.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of process of mould straight forming is provided, comprises the steps:
(1) modeling, uses computer technology to make the three-dimensional stereo model of mould;
(2) data processing, uses special software that the three-dimensional stereo model of mould is carried out layered shaping, obtains a series of cross sectional shape;
(3) powder, sintering is spread, according to the cross sectional shape of step (2) gained, laser beam flying raw materials for sintering powder, solidification obtains the cross section of every layer, after having sintered a layer cross section, workbench moves down one deck, continue the cross section that sintering obtains new one deck, described cross section is stacked until complete whole primary mold layer by layer;
(4) post processing, carry out polishing in the surface of primary mold step (3) made, polishing, then cleans, and again carry out integrally curing, forms finished product die.
In a preferred embodiment of the present invention, described material powder comprises resin, pottery, wax powder, plastic powders or metal dust.
In a preferred embodiment of the present invention, in layered shaping, the THICKNESS CONTROL of every one deck is at 50 μm ~ 500 μm.
In a preferred embodiment of the present invention, mould produces to obtain in rapid shaping room, and described rapid shaping room has heater.
In a preferred embodiment of the present invention, before carrying out step (3), in described rapid shaping room, temperature can be preheated to 50 ~ 70 DEG C, then material powder is preheated to 150 ~ 280 DEG C.
The invention has the beneficial effects as follows: the process of a kind of mould straight forming of the present invention, not only be applicable to the small quantities of rapid mould of single-piece, and the rapid mould of various complexity can be adapted to, core and the die cavity of mould can be produced accurately, compared with traditional digital control processing mfg. moulding die, its production cycle making mould shortens, and manufacturing expense also reduces.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
A process for mould straight forming, comprises the steps:
(1) modeling, uses computer technology to make the three-dimensional stereo model of mould;
(2) data processing, uses special software that the three-dimensional stereo model of mould is carried out layered shaping, obtains a series of cross sectional shape;
(3) powder, sintering is spread, according to the cross sectional shape of step (2) gained, laser beam flying raw materials for sintering powder, solidification obtains the cross section of every layer, after having sintered a layer cross section, workbench moves down one deck, continue the cross section that sintering obtains new one deck, described cross section is stacked until complete whole primary mold layer by layer; In layered shaping, the THICKNESS CONTROL of every one deck is at 50 μm ~ 500 μm; Described material powder comprises resin, pottery, wax powder, plastic powders or metal dust.
(4) post processing, carry out polishing in the surface of primary mold step (3) made, polishing, then cleans, and again carry out integrally curing, forms finished product die.
This process of the present embodiment, carry out in rapid shaping room, described rapid shaping room has heater, before carrying out step (3), in described rapid shaping room, temperature can be preheated to 50 ~ 70 DEG C, again material powder is preheated to 150 ~ 280 DEG C, makes material powder more be applicable to sintering condition.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
