Abstract
The invention relates to preparing and painting methods of a coating of a metal mould casting and rising system. The preparing method comprises the following steps: mixing anhydrous zinc oxide, sodium silicate and anhydrous asbestos powder, after stirring to be uniform, pouring into deionized water with temperature of 65-75 DEG C, and stirring until being completely uniform while pouring. The painting method comprises the following steps: pouring a prepared coating; preheating a mould subjected to sand blasting; painting the mould casting and rising system by using the coating, with thickness of 0.3-0.5 mm; controlling the thickness of the coating of a riser to be 1-3 mm; preheating and fixing, charging the painted metal mould into an insulation furnace for being baked, preheating until the work temperature of the mould is 350-420 DEG C, and keeping for 1-2 hours. According to the coating prepared by adopting the preparing method and the painting method, the casting defects of insufficient casting, cold shut and the like in a production process of the metal mould can be effectively solved. The preparing method and the painting method play a role of well protecting the metal mould, and further ensure that the mould is stable in size and quality.
Description
Technical field
The present invention relates to configuration and the brushing method of metal type dies pouring and riser systems coating, belong to metal type dies application of paints technical field.
Background technology
Compare with sand casting, permanent mold casting can Reusability, meets the theory of united nations environment programme division (UNEP)/green casting, technically with have economically many advantages.But metal mold is airtight, and without deformability, easily cause the casting flaws such as mould misrun, cold shut.For fear of defects such as mould misrun, cold shuts, conventionally at metal type dies pouring and riser systems working surface spray coating, thus the cooling velocity of adjusting mould, to reach the object that improves die quality.But existing coating and spraying and brushing method are still difficult to meet above requirement.
Summary of the invention
In order to overcome above technical problem, the object of the present invention is to provide a kind of preparation and brushing method of metal type dies pouring and riser systems coating, adopt the coating of the method preparation and this brushing method can effectively solve in metal mold production process the defects such as mould misrun, cold shut, sticking to mould.
To achieve these goals, the present invention is by the following technical solutions:
The collocation method of metal type dies pouring and riser systems coating, dry oxidation zinc, waterglass, anhydrous flake asbestos are mixed, after stirring, be poured in the deionized water of 65 ℃～75 ℃, limit bevelling stirs until completely evenly, the proportioning of described dry oxidation zinc, waterglass, anhydrous flake asbestos and deionized water is by weight percentage: dry oxidation zinc 9～11%, waterglass 8～10%, anhydrous flake asbestos 8～11%, all the other are deionized water.
The particle size diameter of described zinc oxide and flake asbestos is less than 0.6mm.
The modulus of described waterglass is 2.5～3.0; Density is 1.50～1.60g/cm
3.
The brushing method that adopts the metal type dies pouring and riser systems coating of said method configuration, comprises the following steps:
1) get the coating having configured in 24 hours;
2) the complete metal type dies of blast is preheating to coating brushing temperature: 280～350 ℃;
3) with coating pen, mould pouring and riser systems is brushed, running channel paint thickness is controlled at 0.3～0.5mm; Rising head paint thickness is controlled at 1～3mm;
4) pre-heat fixation, packs the metal type dies having sprayed in holding furnace into and toasts, and is preheated to 350～420 ℃ of mold work temperature, and keeps 1～2h.
Compared with prior art, the invention has the beneficial effects as follows:
1, the coating of the method for the invention configuration, its viscosity is fine, spray convenience, can on metal mold surface, form uniform thin layer, effectively protect metal mold pouring and riser systems, adjust the cooling velocity at mould each position in metal mold, control solidification sequence, improve gas in die cavity and discharge condition, effectively avoid the defects such as misrun, cold shut, sticking to mould; Can guarantee die size, steady quality, between molten metal and die cavity, form fire-resistant shield layer, improve the scouring capability of molten metal to die cavity, the service life of improving metal mold.
2, brushing method of the present invention is simple to operate, brushing is convenient, and cost of material is cheap.Can effectively avoid the defects such as mould misrun, cold shut, and difficult drop-off, be specially adapted to the magnesium alloys such as aviation, automobile, the production of aluminum alloy metal-type gravitational casting.
3, the particle size diameter of refractory material zinc oxide and flake asbestos is less than 0.6mm, and its fire resistance is good, and adopting modulus is 2.5～3.0, and density is 1.50～1.60g/cm
3waterglass, its caking property is good.
4, before spraying brush material, mould is carried out to sandblast and preheating, sandblast can make the adhesiveness of coating better, and preheating is evaporated rapidly moisture in coating, and the dope layer of spary is even and fine and close.Preheat temperature adopts 280～350 ℃, and spraying effect is best, if preheat temperature is too low, coating can not be dried very soon; Preheat temperature is too high, the easy bubbling of coating or peel off.
5, running channel paint thickness is controlled at 0.3～0.5mm, and rising head paint thickness is controlled at 1～3mm, if spraying is too thin, does not have the effect of the cooling velocity that regulates mould; If spray too thickly, dope layer easily comes off, and can have influence on running gate system size.
