Aluminum alloy die casting die is used to die-casting aluminum alloy, because of the unique plasticity of aluminum alloy, so in the die casting time to pay attention to these points.
What measures should be taken if the die of aluminium alloy die casting dies when it is die casting?
1, improve the fluidity of the alloy:
(1) the correct smelting process is adopted to eliminate gas and non-metallic inclusions.
(2) increase the pouring temperature and die temperature of the alloy.
(3) increasing the injection velocity.
(4) adding nitrogen to raise the effective pressure.
(5) adopting quantitative pouring.
(6) improve the casting structure and adjust the wall thickness properly.
2, improve the gating system:
correct selection of gate location and diversion mode is beneficial to
the use of multiple gates for non - ideal castings and large castings.
(2) increase the cross sectional area of the gate or increase the injection speed.
3, improve exhaust conditions:
(1) adding overflow tank and exhaust duct, and the deep concave cavity can be provided with breather plug.
(2) the use of paint, thin and uniform, dry burn after die.
(3) reduce die temperature to working temperature.
Well, the above is the aluminum alloy die castings, mold cast when the solution.
