Abstract
The invention discloses a kind of casting preparation method of the pump housing, the casting technique of the pump housing comprises the following steps that：1）Design drawing is produced according to the pump housing and makes mould；2）Upper mold, lower mold are copied into resin sand；3）The mixed sand that 50% 75% chrome ore and 15% 35% zircon sand are configured to is replicated into bottom plate core, core；4）Negative pressure；5）Burnt in smelting furnace and melt raw scrap material, obtain water solution；6）Water solution is poured into ladle, obtains pump housing idiosome, treats that air cooling is molded；7）To the pump housing idiosome after shaping after molten metal is hardened and to form metallic article, cover half separates with dynamic model.Using the technical program, the problem of process is more, and workload is big in prior art processing pump housing technology is overcome, improves production efficiency；The mass defect caused by casting dimension processing is unqualified is avoided, utilization rate of raw materials is high, reduces production cost；Technique is simple, and casting dimension accuracy is high, and corrosion resistance and wearability are good.
Description
Technical field
The present invention relates to a kind of casting preparation method of the pump housing, technical field is manufactured applied to electric machine casing.
Background technology
The manufacture of pump body cast requires that casting dimension accuracy is high, in current pump housing pouring technology, manufactured casting finished products
Pump housing rough surface, not only casting process is more, influences production capacity, while the precision of casting can not be effectively ensured, percent defective
It is higher.Therefore, we design a kind of casting preparation method of the pump housing.
The content of the invention
To solve the defects of prior art, the invention discloses a kind of casting preparation method of the pump housing.
The invention discloses a kind of casting preparation method of the pump housing, the casting technique of the pump housing comprises the following steps that：
1）According to pump housing production design drawing making mould, upper mold, the lower mold that mould is made up of upper dynamic model, lower cover half,
Cope is respectively placed in after extrusion forging shaping, in drag box；
2）Upper mold, lower mold are copied into resin sand, the mould of core and core is respectively prepared with Digit Control Machine Tool depending on cavity shape
Tool；
3）The mixed sand that the zircon sand of 50%-75% chrome ore and 15%-35% is configured to replicates bottom plate core, core；
4）Negative pressure, by the air in mold cavity under negative pressure pump air-extraction function, range of negative pressure 0.05-0.07Mpa discharge sand
Air in case；
5）Burnt in smelting furnace and melt raw scrap material, burning melts temperature at 1400-1600 DEG C, adds C：4-8%, Si：2-4%, Mo：0.5-
1.5%, Mn：0.5-0.88%, Ni：0.4-0.9%, Fe：65-75% mixing burning is melted, and obtains water solution；
6）Water solution is poured into ladle, water solution is poured into a mould sandbox at the rising head of fixing mould using ladle
It is interior, pump housing idiosome is obtained, treats that air cooling is molded；
7）To the pump housing idiosome after shaping after molten metal is hardened and to form metallic article, cover half separates with dynamic model.
The beneficial effects of the invention are as follows：Overcome in prior art processing pump housing technology that process is more, workload is big to ask
Topic, improves production efficiency；The mass defect caused by casting dimension processing is unqualified is avoided, utilization rate of raw materials is high, drop
Low production cost；Technique is simple, and casting dimension accuracy is high, and corrosion resistance and wearability are good.
