The invention relates to an anode oxidating dyeing technique of aluminium extruded section product with a plurality of blind holes which has steps as follows: loading, removing oil, washing with clean water, washing and spraying, corrupting with alkali, washing with clean water, washing and spraying, cleaning with ultrasonic, washing with pure water, anode oxidating, cleaning, cleaning and spraying, washing with pure water, processing before dyeing, washing with pure water, dyeing, washing with pure water, closing with nickel salt, cleaning and spraying, washing with pure water, drying in vacuum. The technique changes oxidating film hole by using increase of oxidating temperature and electrolyte concentration for enhancing the film absorption ability to dye; a processing agent before dyeing can avoid poor dyeing effect caused by acid sewage flow in hole, screw hole of the anode oxidating product efficiently, and control poor dyeing effect, white point, color mistiness with flow hanging shape caused by residual medicinal liquor flow in dyeing by increasing dyeing ability of dye; replacement of dyeing agent can greatly increase stability of dyeing and prolong working life of dye, and increase absorption ability of the oxidating film to dye.
