Abstract
The invention discloses an end cover casting production technology. The technology sequentially comprises the steps of sand mould producing, casting mould producing and pouring and cooling; the technology is characterized in that the pouring technology is that firstly cleaning and vacuumizing are carried out on the interior of a casting mould, and then preheating is carried out at the temperature of 800-900 DEG C; secondarily, liquid metal with the temperature of 1000-1200 DEG C is poured into the casting mould, wherein the pouring time lasts for10-12 seconds, the casting mould is sealed and is put in a constant temperature furnace with the internal temperature of 1200 DEG C, wherein the constant temperature time lasts for 30-60 minutes, and then, cooling is carried out; and the cooling technology is that the casting mould is exposed in air for naturally cooling at first, the cooling time lasts for 1-1.5 hours, and then, the casting mould is soaked in water for cooling to be at the normal temperature. A casting has stable quality and few processes, and is 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 end cap.
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 end cap 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 end cap, this technique comprise sand mold making, mold manufacturing and pouring technology and process for cooling successively,
Described pouring technology refers to:
At first, vacuumize clearing up in the mold, carry out afterwards preheating, the temperature of preheating is 800-900 ℃;
Secondly, be that 1000-1200 ℃ liquid metals is poured in the mold with temperature, be 10-12 second the duration of pouring, pressurized mould afterwards, and mold is placed internal temperature is that constant temperature time is 30-60 minute, afterwards cooling in 1200 ℃ the constant temperature oven;
Described process for cooling refers to: at first, mold is exposed to and carries out nature cooling in the air, and be 1-1.5 hour cool time, then, mold is immersed in the water is cooled to normal temperature.
The preheat temperature of described mold is 850 ℃.
The temperature of described liquid metals is 1100 ℃, and be 11 seconds the duration of pouring, and constant temperature time is 40 minutes.
Be 1.3 hours described cool time.
Compared with prior art, beneficial effect of the present invention is:
Because the casting production process of end cap of the present invention has adopted the process conditions of rational processing step and science, so casting quality of the present invention is stable, and operation is few, and is easy to operate.
The specific embodiment
Describe the present invention in detail below in conjunction with the specific embodiment
The casting production process of a kind of end cap of the present invention, this technique comprise sand mold making, mold manufacturing and pouring technology and process for cooling successively,
Described pouring technology refers to:
At first, vacuumize clearing up in the mold, carry out afterwards preheating, the temperature of preheating is 800-900 ℃;
Secondly, be that 1000-1200 ℃ liquid metals is poured in the mold with temperature, be 10-12 second the duration of pouring, pressurized mould afterwards, and mold is placed internal temperature is that constant temperature time is 30-60 minute, afterwards cooling in 1200 ℃ the constant temperature oven;
Described process for cooling refers to: at first, mold is exposed to and carries out nature cooling in the air, and be 1-1.5 hour cool time, then, mold is immersed in the water is cooled to normal temperature.
The casting production process of end cap has adopted the process conditions of rational processing step and science, so casting quality is stable, operation is also few, easy to operate.
Embodiment 1:
A kind of casting production process of end cap, this technique comprise sand mold making, mold manufacturing and pouring technology and process for cooling successively,
Described pouring technology refers to:
At first, vacuumize clearing up in the mold, carry out afterwards preheating, the temperature of preheating is 850 ℃;
Secondly, be that 1100 ℃ liquid metals is poured in the mold with temperature, be 11 seconds the duration of pouring, pressurized mould afterwards, and mold is placed internal temperature is that constant temperature time is 40 minutes, afterwards cooling in 1200 ℃ the constant temperature oven;
Described process for cooling refers to: at first, mold is exposed to and carries out nature cooling in the air, and be 1.3 hours cool time, then, mold is immersed in the water is cooled to normal temperature.
In sum, casting quality of the present invention is stable, and operation is few, and is easy to operate.
The above only is better embodiment 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.
