It can greatly reduce the manufacturing cost and time of mold, getting rid of the extra size of the mold, shrinking it to achieve the goal of light mold.

Description

Mould manufacturing method and structure thereof

Technical field

The present invention relates to a kind of mould structure, particularly a kind of quick Fabrication, accuracy high and lamination type mould manufacturing method and structure thereof cheaply.

Background technology

For the strain arriving in low margin age, all trades and professions are all pursued the reduction of self cost, and effective and efficient manner reduces cost with a large amount of productions exactly for manufacturing industry, the mass-produced most important condition then must provide the mould that casts out this product, utilize filling mold forming mode to make in a large number, but product category must constantly be weeded out the old and bring forth the new now, and the cost of especially consumption electronic products, so mould manufacturing and efficient are the steps of can not ignore.

Mould is a kind of for the injection of melt molding liquid, special implement with moulding reservation shape, structure article, and common shaping dope for example: plastic solution, metallic solution etc., the shaping dope of high temperature is poured in the mould, make model fixed-type this mold cools down again, by ejection system model is ejected, the interior shaping dope of mould is essential to be heated through high temperature earlier so this model is owing to being poured in, so general mould all has cooling system in design again.

Existing mold must be through processing procedures such as borings in addition, therefore need consider the structural strength that each boring processing procedure can bear and the space of reservation at the material of mould and volume, no matter therefore traditional moulds all is one of factor of considering at volume or material, cause the volume of mould and weight to dwindle or to reduce; Moreover carry out cooling step behind the mould filling mould, and also must model be ejected after the cooling by ejection system, therefore mould also must have ejection system in design, add original mould inner mould cave again, so mould process during fabrication complexity very, and above-mentioned die cavity, cooling system and ejection system processing procedure are to use the bore mode gradation to carry out with technology now mostly, so also must expend a large amount of time and money

The present invention is directed to the problems referred to above, propose a kind of mould manufacturing method and structure thereof, can effectively overcome the shortcoming of prior art.

Summary of the invention

The specific embodiment

Mould manufacturing method of the present invention is different from the existing machinery bore mode, no matter at time, precision and the cost of Mold Making improvement is significantly arranged all, below is just explained orally at mould structure and manufacture process.

At first introduce structure of the present invention, with reference to Figure 1 and Figure 2, this mould structure 10 is to be formed by a plurality of thin plate 12 folded establishing, the material of this thin plate 12 is a metal material, and thin plate 12 also can be heat-resisting material in addition, and this mould structure 10 comprises counterdie 14 and patrix 16, this counterdie 14 is provided with one and pours into hole 18, and between counterdie 14 and patrix 16, be provided with a die cavity 20, pour into hole 18 therewith die cavity 20 communicate, this pours into hole 18 and can pour into and flow in this die cavity 20 for the shaping dope of fusion; Be provided with cooling system and ejection system in addition in the mould structure 10 in addition, this cooling system is that form with a plurality of passages 22 presents at this embodiment, ejection system then is to present in the form that counterdie 14 is provided with four through holes 24 at this embodiment, this cooling system can make the shaping dope cooling that pours into form the model body, and ejection system then can eject the model body.

Please be simultaneously with reference to Fig. 2 and shown in Figure 3, because of mould structure 10 is to be formed by a plurality of thin plate 12 folded establishing, so each thin plate 12 is provided with a plurality of patterning openings 26, for example counterdie 14 structural thin plate 12a are provided with the through hole 24 and the die cavity 20 of ejection system of part among Fig. 3, the passage that pours into hole 18 and cooling system 22 that then has part at patrix 16 structural thin plate 12b, respectively with thin plate 12 folded patrix 16 and the counterdies 14 of being set as, the folded back patrix 16 of establishing can formation pour into hole 18, the passage 22 of cooling system and the depressed part of die cavity 20, counterdie 14 then can form the through hole 24 of ejection system, the passage 22 of cooling system and the protuberance of die cavity 20; Therefore the patterning opening 26 on each thin plate 12 can be selected from die cavity 20, pour into a wherein part of hole 18, cooling system and ejection system because of the folded position difference of establishing, establish when forming mould structure 10 when these thin plates 12 are folded, each patterning opening 26 is stacked and is formed a plurality of cavitys, and these cavitys just comprise the passage 22 that pours into hole 18, die cavity 20, cooling system and the through hole 24 of ejection system.

Then introduce the manufacture method of this mould, please refer to shown in Figure 4, at first carry out step S1, this step is by Computer Simulation, also the notion that is about to the designer is set up product model in computer, and on the model of being set up, set up out mould, and in mould, add cooling system, ejection system etc., then the model of being set up is carried out emulation section (slicing), produce embryo rapidly with the mode and the form of stacking layer by layer, Chang Yong computer software can be selected Autocad now, Solid-work or PRO-ENGINEER etc., therefore can learn the minimum area of each section by Computer Simulation, thickness and the position is set produces mould in folded mode of establishing.

Then carry out step S2 according to the data that computer calculated, this step S2 prepares a plurality of sheet metals, this thin plate can be formed by cutter cutting or laser cutting, then carry out step S3, this step is the one or more patterning openings of cutting on each thin plate, and this patterning number of openings, position and area all are that the data that calculate according to computer are cut; Then carry out lamination procedure of processing S4, this step must be carried out under vacuum state, this step is the thin slice that each cutting is finished to be folded establish, wherein can utilize adhesive agent between each thin slice, the metal welding, laser spot welding, modes such as electric resistance welding or ultrasonic joint are folded and are established, and each thin slice is finished the preliminary form of back formation mould folded establishing, and this step mode commonly used is a laser spot welding, laser spot welding is laser directly to be penetrated do accurate welding on the pad of sheet surface, therefore this welding only produces the heat of a little, so other partly can't be influenced; The metal welding then is at thin sheet surface the layer of metal layer to be set, and utilizes HTHP to make to form alloy between metal level and the thin plate and thin plate is engaged, and this metal level is a copper metal layer.

And each thin slice is behind storehouse, and the patterning opening storehouse on each thin slice forms a plurality of cavitys, and these cavitys comprise die cavity, cooling system passage, ejection system through hole and the hole that pours into of shaping dope input is provided; Carry out step S5 at last, this step is to carry out the surface treatment of thin portion at die surface, and this surface treatment is to utilize high temperature to make the trickle fusion of die surface, makes die surface present smooth effect, can finish mould structure 10 as shown in Figure 1.

The above is by embodiment characteristics of the present invention to be described, its objective is that person skilled can understand content of the present invention and implement according to this, rather than be used for limiting claim of the present invention, therefore other does not anyly break away from the identity property that spirit set forth in the present invention finishes and modifies or revise, and must be included in the claim scope of the present invention.
