Abstract
The invention discloses a magnesium alloy profile extrusion die cleaning device and method. The method comprises the following steps of: separating a left half die from a right half die of a magnesium alloy profile extrusion die; placing a sleeve-shaped right half die cushion on a platform of a press, and placing the right half die which is filled with magnesium alloy in a tap hole on an extrusion die cushion; assembling an extruding punch on a slide block of the press, adapting the lower end of the right half die to the appearance of the tap hole one the right half die; and driving the extruding punch to move downward by the slide block of the press, extruding the residual magnesium alloy from the tap hole of the right half die, and leading the residual magnesium alloy in a tube cavity of the extrusion die cushion. By adopting the method for cleaning the magnesium alloy profile extrusion die, the extrusion punch is driven to extrude the magnesium alloy left in the right half die through the press; and compared with the conventional method for cleaning the extrusion die of the magnesium alloy profile, a section of the aluminum bar is saved, and alkali consumed when the die is boiled and energy consumed in heating alkaline water can be saved simultaneously.
