Abstract
The invention discloses a casting production process of shells. The process comprises sand mold manufacturing, casting mold manufacturing and a pouring process in sequence and is characterized in that the pouring process comprises the steps of firstly preheating a casting mold by adopting a preheating device, secondly pouring the liquid metal at 1300-1500 DEG C into the casting mold, thirdly sealing the casting mold after liquid metal pouring is completed and putting the casting mold into a constant temperature furnace with internal temperature of 1500 DEG C and finally cooling the casting mold through a cooling process, wherein the preheating device comprises a first temperature zone at 100-200 DEG C, a second temperature zone at 300-500 DEG C and a third temperature zone at 600-800 DEG C; and the constant temperature time is 1-3 hours. The casting production process is stable in casting quality, less in procedures and easy to operate.
Description
Technical field
The present invention relates to a kind of casting production process, relate in particular to a kind of casting production process of housing.
Background technology
Casting refers to liquid metals is cast in the casting cavity that adapts with part shape, after its cooled and solidified, to obtain the method for part or blank, obtain foundry goods cast member by casting method, because the cast member production technology is simple and cost is lower, so increasing mechanical part is preferentially selected cast member, but cast member also exists casting quality unstable when casting, the defective that operation is various and problem.
Summary of the invention
It is stable that technical problem to be solved by this invention provides a kind of casting quality, the casting production process of the housing that operation is less.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of casting production process of housing, this technique comprises sand mold making, mold manufacturing and pouring technology successively, described pouring technology refers to: at first, adopt preheating device that mold is carried out preheating, described preheating device comprises that temperature is the three-temperature-zone that the first warm area of 100-200 ℃, the second temperature that temperature is 300-500 ℃ and temperature are 600-800 ℃, secondly, be that 1300-1500 ℃ liquid metals is poured in the mold with temperature; Then, be poured rear pressurized mould until liquid metals, it is that constant temperature time is 1-3 hour in 1500 ℃ the constant temperature oven that mold is placed internal temperature; , last, make the mold cooling by process for cooling.
Described process for cooling refers to: comprise successively air-cooled and recirculated water cooling, the air-cooled time is 30-50 minute, by recirculated water cooling mold is cooled to normal temperature at last.
Described the first warm area is 150 ℃, and described the second warm area is 400 ℃, and described three-temperature-zone is 700 ℃.
Described constant temperature time is 2 hours.
Compared with prior art, beneficial effect of the present invention is:
Since the casting production process of housing of the present invention before cast with mold preheating in the warm area of three different temperatures, surface quality that like this can the Effective Raise finished product, and technique is simple, easy to operate, so casting quality of the present invention is stable, operation is few, and is easy to operate.
The specific embodiment
Describe the present invention in detail below in conjunction with the specific embodiment
A kind of casting production process of housing, this technique comprises sand mold making, mold manufacturing and pouring technology successively, described pouring technology refers to: at first, adopt preheating device that mold is carried out preheating, described preheating device comprises that temperature is the three-temperature-zone that the first warm area of 100-200 ℃, the second temperature that temperature is 300-500 ℃ and temperature are 600-800 ℃, secondly, be that 1300-1500 ℃ liquid metals is poured in the mold with temperature; Then, be poured rear pressurized mould until liquid metals, it is that constant temperature time is 1-3 hour in 1500 ℃ the constant temperature oven that mold is placed internal temperature; , last, make the mold cooling by process for cooling.
By the arrangement of above-mentioned processing step and process conditions, make at first preheating in without the warm area of temperature of mold, thereby make mold reach best casting condition, thereby can further improve the surface quality of finished product, make casting quality stable.
Embodiment 1:
A kind of casting production process of housing, this technique comprises sand mold making, mold manufacturing and pouring technology successively, described pouring technology refers to: at first, adopt preheating device that mold is carried out preheating, described preheating device comprises that temperature is the three-temperature-zone that the first warm area of 150 ℃, the second temperature that temperature is 400 ℃ and temperature are 700 ℃, secondly, be that 1400 ℃ liquid metals is poured in the mold with temperature; Then, be poured rear pressurized mould until liquid metals, it is that constant temperature time is 2 hours in 1500 ℃ the constant temperature oven that mold is placed internal temperature; , last, make the mold cooling by air-cooled and recirculated water cooling successively, the air-cooled time is 40 minutes, by recirculated water cooling mold is cooled to normal temperature at last.
In sum, casting quality of the present invention is stable, and operation is few, and is easy to operate.
The above only is preferred embodiments of the present invention; protection scope of the present invention is not limited with above-mentioned embodiment; as long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection domain of putting down in writing in claims.
