Abstract
The casting method for booster compressor casing comprises the casting of dynamic and fixed compression molds, forming cavity between them, with the said compression mold having sprue connected with said cavity, compressing the casting melt into the cavity using the pressure 23-30MPa, keeping for certain time to open the dynamic mold to eject the booster compressor casing casting piece. It can boost production efficiency, simplify process, reduce product weight, defect and production cost. It also relates to the casting equipment for the booster compressor casing.
Description
Technical field
The present invention relates to mechanical field, particularly a kind of casting method of compressor casing of pressurizer and compressor casing of pressurizer.
Background technology
At present, what the casting of known compressor casing of pressurizer was adopted is the core casting method, and this casting method will be done the core mould earlier, make the core compressor casing of casting again, also will break core into pieces after casting is good and pour out, and core is disposable, the casting process complexity is loaded down with trivial details, casting cost height, compressor casing surfaces externally and internally roughness is low, and particularly whether unimpeded directly influence air-flow for the inner flow passage roughness, influence efficiency of turbocharger, it is big to consume the aluminium amount simultaneously, and product cost is than higher, and weight is big.The compressor casing that above-mentioned casting method is produced produces defectives such as pore, sand holes easily at diffusion face 4, small end 3 and radian 2 places, and its casting technique is loaded down with trivial details, and Heavy Weight, inside surface roughness are not high, cost is big, compressor efficiency is low.
Summary of the invention
The technical problem to be solved in the present invention is intended to overcome the deficiency of above-mentioned prior art, and a kind of casting method of compressor casing of pressurizer is provided, and this method can be simplified casting technique, reduces the casting flaw that produces because of casting.
The technical solution used in the present invention is:
The casting method of compressor casing of pressurizer may further comprise the steps:
1) preparation includes the die-casting die of ejector half and typing, forms die cavity between described ejector half and the typing, and described die-casting die is provided with the cast gate with above-mentioned die cavity UNICOM;
2) above-mentioned ejector half and typing are lumped together;
3) will cast liquid and be pressed in the die cavity by cast gate with the injection pressure of 23～30MPa, certain hour keep-ups pressure;
4) open ejector half, eject the compressor casing of pressurizer foundry goods.
Compared with the prior art the casting method of compressor casing of pressurizer of the present invention has following good effect: under the situation that does not change other any parts, can improve supercharger air compressor efficient, simultaneously can simplify casting, processing technology, alleviate product weight, minimizing has reduced process equipment, has reduced production cost because of the casting flaw that casting produces.
Another technical problem that this aspect will solve provides the casting method that adopts above-mentioned compressor casing of pressurizer and the compressor casing of pressurizer of casting, the diffusion face 4 of this compressor casing of pressurizer, small end 3 and radian 2 place's pore-frees, sand holes, and the surface roughness at its inner flow passage 1 and other each positions improves greatly.
Description of drawings
Fig. 1 represents the structure cutaway view of the compressor casing of pressurizer that the present invention relates to;
Fig. 2 represents the Facad structure figure of the compressor casing of pressurizer that the present invention relates to.
The specific embodiment
With reference to accompanying drawing 1 and Fig. 2, will be described in detail the specific embodiment of the present invention.
