Description
Technical field
This patent relates to field of machining, relates in particular to mould and manufacture method thereof.
Background technology
At present, the part of many electronic products, automobile etc. is all produced by mould, and mould owing to its advantage aspect the production and processing cost, has become the first-selection of product, part processing production as the important element of field of machining day by day.
Mould briefly, is used for the instrument of shaped article or part exactly.According to the difference of shaped article, mould is divided into metal die and nonmetal mould, typical case's representative of the product of metal die moulding is exactly aluminium alloy, magnesium-alloy material, and typical case's representative of the product of nonmetal mould moulding is exactly pottery.And according to making the material difference that described mould uses, described mould is divided into sand mold mould, metal die, paraffin mould etc.
The metal material of making metal die is generally alloy, as the nickel nickel-chrome alloy steel.Utilize alloy mold contour alloy product, as magnesium alloy or alloy product, because the alloy mold long-term work is in high-temperature fusant magnesium alloy or aluminium alloy environment, composition in the alloy mold is flowed in the described shaped article, be that described alloy mold is corroded by shaped article or part, and then shortened the service life of described alloy mold, often behind several thousand products of described alloy mold moulding or part, namely need to repair to touch, even scrap.As everyone knows, the cycle of producing described alloy mold is longer usually, and cost is very high.But as mentioned above, the service life of alloy mold is so short, therefore, when needs shaped article in enormous quantities or part, described alloy mold need often repair a die or die sinking again, cause the production cost of producing described product or part to increase, be unfavorable for improving the market competitiveness of product or part.

Description of drawings
Fig. 1 is the flow chart of manufacture method of the mould of a preferred embodiments.
The specific embodiment
A kind of mould that this patent provides, it is mainly used in shaped article and the part of alloying or metal material.Described mould adopts aluminium oxide to form for the primary raw material manufacturing, described aluminium oxide is mainly used in forming the principal crystalline phase of described mould in the forming process of described mould, make intensity and the rigidity of the described mould after the moulding be only second to diamond, and the cost of described aluminium oxide is lower, can reduce described mould production cost.
In the material of making described mould, also comprise Suzhou soil, silica, organic dispersing agent, plasticizer, surfactant etc.The main component of described Suzhou soil is aluminium oxide and silica, and described Suzhou soil and silica are mainly used in reducing the sintering temperature of described mould in the forming process of mould, helps described mould to generate glassy phase simultaneously.Described organic dispersing agent, plasticizer, surfactant are used for making the various materials of making described mould fully to mix, and the various materials of mfg. moulding die are better combined, and are convenient to the moulding of described mould.In the present embodiment, described plasticizer is aliphatic dibasic acid fat, and described surfactant is carboxymethyl cellulose.
In the various materials of the described mould of above-mentioned manufacturing, the proportion of the composition of described aluminium oxide in entire die is between 93.5% to 97%, and described Suzhou soil, silica, organic dispersing agent, plasticizer, the proportion of surfactant in entire die are between 6.5% to 3%.
See also Fig. 1, it makes the method flow schematic diagram of described mould for adopting above-mentioned material.The manufacturing of described mould need be passed through following steps:
S101: the various materials that will make described mould are pulverized and fully mixing.Described various material comprises aluminium oxide, Suzhou soil, silica, organic dispersing agent, plasticizer, surfactant etc., and the shared ratio of wherein said aluminium oxide is between 93.5% to 97%, and the shared ratio of other material is between 6.5% to 3%.After the described material preparation, through ball mill grinding, fully mix then, with standby.
S103: be the blank with regular shape with above-mentioned abundant mixed forming materials.Described mixed material is shaped to the blank with regular shape by the isostatic compaction method.
S105: above-mentioned blank is carried out pre-burning.Described blank is arranged in 900 to 1000 degrees centigrade environment pre-burning in temperature, makes described blank have certain rigidity and rigidity, so that processing also is unlikely to make simultaneously described mould broken diffusing.
S107: the blank of pre-burning being finished according to the definite size of the mould of described needs manufacturing carries out the car base.Consider the shrinkage factor of described blank, described blank is being carried out in the process of car base, need make the size of the elementary mould behind the car base need the size of the mould made bigger, stay leeway to give follow-up repairing a die.
S109: the elementary mould behind the above-mentioned car base is carried out high temperature sintering.Described elementary mould is arranged in environment sintering more than 1650 degrees centigrade in temperature, so that the strength and stiffness of above-mentioned elementary mould reach the requirement that needs the mould made.
S111: the definite size of the mould of making according to described needs, the mould that described high temperature sintering is finished is polished.Because in step S107, described elementary mould does not pass through high temperature sintering, the performance of its some aspect and parameter are not finally determined as yet, so the size to described elementary mould is allowed some leeway in step S107.And through the mould behind the high temperature sintering, the performance of its each side and parameter are all stable, so need be according to the mould that the definite size of the mould of described needs manufacturing is finished the described high temperature sintering processing of polishing, mould behind the described high temperature sintering is reached need the requirement of the mould of making.
S113: check whether the size of the mould that above-mentioned polishing is finished and the size between the described mould that needs to make coincide.If coincide, then the manufacturing of described mould is finished, otherwise, then need to continue execution in step S111, till described mould reaches requirement.
In the manufacture method of above-mentioned mould and mould, because to have adopted with the aluminium oxide be that main material is made described mould, and the more traditional cost of alloy of the cost of described aluminium oxide is much lower, makes the production cost of described mould be lower than the mould that tradition adopts alloy.Compare with the mould that tradition adopts alloy material to make, that employing provided by the invention with the aluminium oxide is that the mould of main material production has is high temperature resistant, strength and stiffness are strong; Because described mould is in the process of shaped metal articles, the alumina composition of described mould not with the metal ingredient of described metal product take place in conjunction with or reaction, the life-span that makes described mould adopts the life-span of the mould that metal material makes long than tradition.In addition, by described aluminium oxide be the weight mould made of the metal material that adopts of tradition in light weight of the mould of main material production.The shrinkage factor of mould provided by the present invention and the shrinkage factor of metal have notable difference, the demoulding after moulding of the product of described mould easy to use.
