[0038] Working principle: before using the die casting mold mass exhaust and vacuum dual-purpose structure, the overall situation of the device needs to be checked to determine whether it can work normally, according to Figure 1 - Figure 5As shown, when vacuum is needed, the vacuum pump connected by the vacuum pipe 102 is used to pump air, so that the mold connected with the separation bin 1 through the docking groove 216 can be pumped, and when pressure casting is performed, part of the liquid aluminum will enter the separation bin 1, part of it will splash and quickly cool and solidify after falling into the water, and the other part will flow along the inner wall of the separation bin 1 and solidify along the inner wall of the separation bin 1;
