Cooling device for aluminum alloy machining

Abstract

The invention discloses a cooling device for aluminum alloy machining, and belongs to the technical field of aluminum alloy machining. According to the scheme, molten aluminum alloy is poured into a bearing mold, and ammonium chloride powder can be promoted to be heated and decomposed by means of heat in the bearing mold, so that a phase-change heat dissipation hose expands rapidly, magnetic shielding on a built-in magnetic ball is relieved, under the repulsive action of a traction magnetic hemisphere, the phase-change heat dissipation hose is promoted to expand and make full contact with cooling liquid far away from the phase-change heat dissipation hose, the phase-change heat dissipation hose contracts after the temperature is reduced, and the magnetic shielding on the built-in magnetic ball is relieved; on one hand, by the aid of the continuous decomposition and composition of the built-in magnetic ball, the cooling efficiency of the molten aluminum alloy in the bearing mold can be increased; and on the other hand, a bubbling hemisphere is extruded under the contraction effect of the phase-change heat dissipation hose, the bubbling hemisphere is promoted to bulge out a bubbling round hole in the bubbling hemisphere, and therefore the flowing efficiency of the cooling liquid near the bearing mold is increased, and then the cooling effect on the molten aluminum alloy in the bearing mold is improved.
