Abstract
Metal gravity pouring technology, it is characterised in that：Including following technical process：1) mold cleaning, polishing cleaning is carried out with wire wheel to die surface, makes die surface smooth, and the casting demoulding is easily disengaged；2) preheat, pre-heating temperature elevation is carried out to mould with liquefaction gas flame, mold temperature general control is at 95-105 DEG C；3) special coating is sprayed, the special heat-resisting paint of last layer is applied with spray gun to mold cavity surfaces, by spray paint temperature control at 250 DEG C 300 DEG C, coating also needs to carry out mould heating, drying after spraying well, to remove the moisture in coating；4) die trial, preparation finish after by carry out die trial, after having a fling at 1 to 2, observation mould whether reach upstate；5) pour into a mould, die trial is normally poured into a mould after having no problem.Technique of the invention has paint adhesion strong, and the depanning rate of product is high, and the advantages of high yield rate, yield rate can reach more than 95%.
Description
Technical field
The present invention relates to a kind of pouring technology, more particularly to a kind of metal gravity pouring technology.
Background technology
When existing metal gravity is poured into a mould, mould is preheating to 100 DEG C or so by general liquefaction gas flame, and then spray paint is poured into a mould.In this case, cast start 2 to 3 of product are second-rate, start to take a turn for the better with latter made casting quality, and as again the rising of mold temperature, the quality of casting start continuous decrease, final up-to-standard rate is generally 80% or so.
The content of the invention
The purpose of the present invention is exactly the defect and deficiency to overcome above-mentioned prior art to exist, and provides a kind of paint adhesion by force, product depanning rate metal gravity pouring technology high.
The technical scheme of use is：
Metal gravity pouring technology, it is characterised in that including following technical process：
1st, mold cleaning
Polishing cleaning is carried out to die surface with wire wheel, makes die surface smooth, the casting demoulding is easily disengaged.
2nd, preheat
Pre-heating temperature elevation is carried out to mould with liquefaction gas flame, mold temperature general control is at 95-105 DEG C.
3rd, special coating is sprayed
After reaching temperature, the special heat-resisting paint of last layer is applied with spray gun to mold cavity surfaces, spray paint temperature is scheduled on 250 DEG C -300 DEG C or so, toasted and sprayed with carbon fire.When mold temperature is increased to more than 300 DEG C, wind cooling temperature lowering is used.The temperature of mould is thus maintained no more than 300 DEG C, and in time by the coating that filled spray at stripping pattern, is then poured into a mould again, coating also needs to carry out mould heating, drying after spraying well, to remove the moisture in coating.
4th, die trial
Preparation finish after by carry out die trial, after having a fling at 1 to 2, observation mould whether reach upstate.
5th, pour into a mould
Die trial is normally poured into a mould after having no problem.
It is of the invention that spray paint temperature is scheduled on 250 DEG C -300 DEG C or so by putting into practice and summarizing, toasted and sprayed with carbon fire.When mold temperature is increased to more than 300 DEG C, wind cooling temperature lowering is used.The temperature of mould is thus maintained no more than 300 DEG C, and in time by the coating that filled spray at stripping pattern, is then poured into a mould again.Discovery when actual production is carried out after optimize technique, paint adhesion is strong, and the depanning rate of product is significantly improved, and yield rate can reach more than 95%.
The present invention has advantages below compared with prior art：
Discovery when actual production is carried out after optimize technique, technique of the invention has paint adhesion strong, and the depanning rate of product is high, and the advantages of high yield rate, yield rate can reach more than 95%.
Specific embodiment
Metal gravity pouring technology, specifically includes following technical process：
1st, mold cleaning
Polishing cleaning is carried out to die surface with wire wheel, makes die surface smooth, the casting demoulding is easily disengaged.
2nd, preheat
Pre-heating temperature elevation is carried out to mould with liquefaction gas flame, mold temperature general control is at 100 DEG C or so.
3rd, special coating is sprayed
After reaching temperature, the special heat-resisting paint of last layer is applied with spray gun to mold cavity surfaces, by spray paint temperature control at 295 DEG C.Coating also needs to carry out mould heating, drying after spraying well, to remove the moisture in coating.
General principle of the invention, principal character and advantage has been shown and described above.It should be understood by those skilled in the art that; the present invention is not limited to the above embodiments; merely illustrating the principles of the invention described in above-described embodiment and specification; without departing from the spirit and scope of the present invention; various changes and modifications of the present invention are possible, and these changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appending claims and its equivalent circle..
