Abstract
The casting method of the present invention's long runner thin wall type casing: one, adopt metal pattern low pressure casting mode, note pressure use pressure at 0.6-0.8MP/cm
2; Two, product integrality and density safeguard measure: establish newly on plane mould and note aluminium feeding chute, meeting the thin-wall part product cast out has higher, more uniform density; Three, technology controlling and process: metal die is heated distribution: one, 420 degree, Chong Xing district, two, flat-die face (die) 410 degree, three, punch 400 degree; Four, safeguard measure: mold exterior warming plate is packed; Five, the shaping of S shape runner: adopt the diameter 5.9 millimeters of S shape copper tubes be supported on concave-convex mold to make flow passage chamber; Six, auxiliary material: select zinc oxide, boron nitride coating; Seven, cooling provision (product shaping crucial): while filling shape, S shape copper tube must be made cooling airway and be blown into compressed air at and just can guarantee that product is intact.
Description
Technical field
This long runner thin wall type casing casting method belongs to casting field, especially aluminum alloy low-pressure casting field.
Background technology
The aluminium alloy thin-walled Complex Parts of new research and development product, requires on the casing baseplane of wall thickness two millimeters, to cast out diameter six millimeters, S shape length 1,500 millimeters, the runner that wall thickness is two millimeters; The inspection of runner ne-leakage adopts medium: kerosene, pressurize 34 kilograms of six hours ne-leakages; Record without casting case through retrieval, be also ready to accept without casting unit.
Summary of the invention
The casting method of the present invention's long runner thin wall type casing:
One, adopt metal pattern low pressure casting mode, note pressure use pressure requirements at 0.6-0.8MPa;
Two, product integrality and safeguard measure: establish newly on plane mould and note aluminium feeding chute, meeting the thin-wall part product cast out has higher, more uniform density;
Three, technology controlling and process: metal die is heated distribution: one, Chong Xing district---420 degree, two, flat-die face (die) 410 degree, three, punch 400 degree;
Four, safeguard measure: mold exterior warming plate is packed;
Five, the shaping of S shape runner: adopt the diameter 5.9 millimeters of S shape copper tubes be supported on concave-convex mold to make flow passage chamber;
Six, auxiliary material: select zinc oxide, boron nitride coating;
Seven, cooling provision (product shaping is crucial): while filling shape, S shape copper tube must be made cooling airway and be blown into compressed air at.
Detailed description of the invention
The casting method of the present invention's long runner thin wall type casing: adopt metal pattern low pressure casting; Copper tube annealing cooling rear enclosed one, pour into stainless shot be shaped after, clear up, blow logical; Increase note aluminium feeding chute on plane mould; Mold exterior warming plate is packed; Heating mould to 250 spends rear even application zinc oxide coating, then sprays boron nitride coating; Continue to heat to one, Chong Xing district---420 degree, two, flat-die face (die) 410 degree, three, punch 400 degree; Even application boron nitride coating after heating; Put into S shape copper tube after mould to temperature to fix, reserve one and make air blowing cooling vent; Inject 710 degree, pressure is blown into compressed air S shape copper tube one while the aluminum alloy melt of 0.6-0.8MPa, guarantees that S shape copper tube is not filled shape fusing; With aluminium argon welding, exposed S shape copper tube fixing point soldering is sealed after product stripping cooling; Copper tube is dissolved by the nitric acid liquid of percent 60; The inspection of runner ne-leakage adopts medium: kerosene, pressurize 34 kilograms of six hours ne-leakages; Polishing, Ageing Treatment, by figure machined.
Claims (1)
