Mold structure for injection molding of a light alloy and method of injection molding a light alloy using the same |
摘要 |
In order to provide a die structure for injection molding of a light alloy free from gas defects, and a method of molding light alloy parts using the die, the die structure is used for converting a light alloy into a semi-molten state, wherein a solid phase and a liquid phase coexist, or a molten state at a temperature just above a melting point and injecting the molten metal into an interior cavity portion, and S1/S2 of a gate sectional area S1 with respect to a maximum sectional area S2 of the cavity of the mold which area is almost perpendicular to the flowing direction of the melt therein is set in a range of 0.06 to 0.5. <IMAGE> |
