Description
Technical field：
The present invention relates to casting techniques field, and in particular to a kind of shock resistance mould and its manufacture method.
Background technology：
In castings production, the quality of mould directly influences the quality of later stage casting, when traditional mould produces due to
Formula and technological problemses, the mould shock resistance degree produced is inadequate, causes the later stage during castings production is carried out, by it
He casting equipment beats, collides and during other external impacts, often results in burn failure, and service life is low, in production,
Once burn failure, if can not change in time, manufacturing schedule is influenceed again, causes production efficiency low.
The content of the invention：
The technical problems to be solved by the invention are to overcome existing technological deficiency, there is provided a kind of shock resistance mould and its
Manufacture method, the mould shock resistance degree that solution prior art is produced is inadequate, causes the later stage during castings production is carried out, by
Beat, collide and during other external impacts to other casting equipment, often result in burn failure, service life is low, is producing
In, once burn failure, if can not change in time, has an impact manufacturing schedule, the problem of causing production efficiency low, the mould
Impact resistance ability is improved, extends service life, the production efficiency and the quality of production of casting is improved, substantially increases enterprise
Economic benefit.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of shock resistance mould, it is characterised in that be made up of the raw material of following parts by weight：
Attapulgite clay 18-25%, limestone sand 35-40%, gangue 30-35%, adhesive 3-5%, intensive 3-
5%；
Preferably, it is made up of the raw material of following parts by weight, attapulgite clay 20%, limestone sand 40%, gangue
30%th, adhesive 5%, intensive 5%；
Preferably, it is made up of the raw material of following parts by weight, attapulgite clay 25%, limestone sand 35%, gangue
35%th, adhesive 3%, intensive 2%.
Described adhesive is one or more of mixing of polystyrene, polyacrylate, ethylene-vinyl acetate copolymer
Thing, bonding effect is good after high-temperature heating fusing, and manufactured die adhesion degree is high, and service life is longer.
The intensive is aluminum matrix composite, increases the shock resistance effect of mould, solves traditional moulds shock resistance degree not
It is enough, beaten, collide and during other external impacts by other casting equipment, the problem of often resulting in burn failure, improve
The impact resistance ability of mould, extends the mold use life-span.
A kind of manufacture method of shock resistance mould, it is characterised in that by the raw material of above-mentioned parts by weight, by following steps system
：
1) pulverize and sieve：After attapulgite clay, limestone sand and gangue are crushed by pulverizer, after sieving removal of impurities
It is standby to compound；
2) parch is heated：Above-mentioned compound is heated into parch by parcher, heating degree is arranged on 230-280 DEG C, parch
2-3 hour of time, it is standby to obtain clinker；
3) cool down：Above-mentioned clinker is cooled down by ultralow temperature, it is standby to obtain freeze-dried powder；
4) mix：Above-mentioned freeze-dried powder is put into stirred tank to mix, adds adhesive, intensive and water, water and raw material

6) it is cooled and shaped：After mould semi-finished product are cooled and shaped, i.e. finished product mould.
Beneficial effects of the present invention are：A kind of shock resistance mould and its manufacture method are provided, prior art is solved and produces
Mould shock resistance degree it is inadequate, cause the later stage during castings production is carried out, beaten by other casting equipment, collide and
During other external impacts, burn failure is often resulted in, service life is low, in production, once burn failure, if can not be timely
Change, have an impact manufacturing schedule, the problem of causing production efficiency low, method provided by the invention, by pulverizing and sieving, remove
Impurity in raw material, consummate mixed material is obtained, dried by heating so that raw material internal component is mutually mixed reaction, passes through
Ultralow temperature is cooled down, and heated sealed is stirred so that composition mutually merges more thorough between raw material, while adhesive is with adding
Thoroughly combined between agent and other raw materials by force, final sintering, base, cooling obtain finished product die so that the mould of finished product has knot
Structure is close, shock proof characteristic, and the mould improves impact resistance ability, extends service life, improves the production effect of casting
Rate and the quality of production, substantially increase Business Economic Benefit.
