Abstract
The invention discloses a kind of casting method of the pump housing, pump housing casting method provided by the invention, including resin sand is used as raw material, and sand mold is made using resin sand, with forming resin bonded sand mould after mould mould assembling, then the making of potting syrup is carried out, the degree of its material chemical component is as follows：C：3.0‑3.2%；Si：1.8‑2.0%；Mn：0.4‑0.5%；P：0.08%；S：0.01%；Mg：0.03‑0.04%；Re：0.01‑0.02%；Cu：0.6 0.8% or Sn：0.04‑0.05%；Remaining is Fe；Above-mentioned raw materials are heated to smelting temperature in electric furnace, make alloy fully melt to form molten iron, form potting syrup；Described potting syrup is poured into a mould into resin bonded sand mould, casting is formed after solidification；After casting all cooling, through sand removal, then it is heat-treated.Technical scheme improves production efficiency, reduces production cost, and casting quality has been effectively ensured.
Description
Technical field
The present invention relates to casting field, specially a kind of casting method of the pump housing.
Background technology
The manufacture of pump body cast requires that casting dimension accuracy is high, in the pouring procedure of the current pump housing, manufactured finished product casting
Part hardness is inadequate, and not only casting process is more, influences production capacity, while the precision of casting can not be effectively ensured, percent defective compared with
It is high.
The content of the invention
In order to overcome above-mentioned technical problem existing for prior art, it is an object of the present invention to provide a kind of pump housing
Casting method, pump body cast can be directly cast out, the precision of casting is high, and processing method is simple.
Pump housing casting method provided by the invention, comprises the following steps：
(1) using resin sand, the degree of its composition is as follows for raw material：Resin 0.9-1.1%；Curing agent 0.3-0.4%；
Remaining is molding sand；
(2) described resin sand is used to make sand mold, with forming resin bonded sand mould after mould mould assembling；
(3) making of potting syrup, material composition and the mixed sand being configured to is replicated into bottom plate core, core, core is assigned in advance
In upper/lower die, the die cavity of core composition carries out bottom pour mold；The degree of its material chemical component is as follows：C：3.0-3.2%；
Si：1.8-2.0%；Mn：0.4-0.5%；P：0.08%；S：0.01%；Mg：0.03-0.04%；Re：0.01-0.02%；
Cu：0.6-0.8% or Sn：0.04-0.05%；Remaining is Fe；
(4) above-mentioned raw materials are heated to smelting temperature in electric furnace, make alloy fully melt to form molten iron, built in ladle
Hole in be put into nodulizer, and coverage inoculator, by molten iron pour into ladle carry out nodularization, inoculation, formed potting syrup；
(5) described potting syrup is poured into a mould into described resin bonded sand mould, casting is formed after solidification；
(6) after casting all cooling, through sand removal, then it is heat-treated.
The casting method of the pump housing provided by the invention, its advantage are, overcome prior art processing pump body cast
The problem of process is more, and workload is big, improve production efficiency；Avoid potting syrup processing it is unqualified caused by mass defect,
Utilization rate of raw materials is high, reduces production cost；The casting dimension of the finished product cast out is accurate, without machining, effectively protects
Casting quality is demonstrate,proved.
Embodiment
A kind of casting method of the pump housing of the present invention is described in further detail with reference to embodiment.The signal of the present invention
Property embodiment and its illustrate be used for explain the present invention, do not form inappropriate limitation of the present invention.

Cu：0.6-0.8% or Sn：0.04-0.05%；Remaining is Fe；
(4) above-mentioned raw materials are heated to smelting temperature in electric furnace, make alloy fully melt to form molten iron, built in ladle
Hole in be put into nodulizer, and coverage inoculator, by molten iron pour into ladle carry out nodularization, inoculation, formed potting syrup；
(5) described potting syrup is poured into a mould into described resin bonded sand mould, casting is formed after solidification；
(6) after casting all cooling, through sand removal, then it is heat-treated.
Pump housing casting method, pump body cast can be directly cast out, without machining, process is simple, the finished product cast out
Casting dimension it is accurate, casting quality has been effectively ensured.
It is described above, only it is embodiments of the invention, not the present invention is imposed any restrictions, it is every according to the technology of the present invention
Any simple modification, change and the change of equivalent method that essence is made to above example, still fall within the technology of the present invention
In the protection domain of scheme.
