Title:
METHOD FOR SEMI-MOLTEN OR SEMI-SOLIDIFIED MOLDING
Document Type and Number:
WIPO Patent Application WO/2011/027769
Kind Code:
A1
Abstract:
In the disclosed method for semi-molten or semi-solidified molding, a semi-molten or semi-solidified metal fills from a columnar part through a runner (54) into a cavity (13) that is a casting space of a scroll member (50) formed within a mold (2). Moreover, the method is characterized by the angle of intersection (θ1), which is the angle at which the runner (54) and the columnar part intersect, being such that 97°≤θ1<135°, and/or the ratio R/√S of the radius of curvature (R) of a chamfed section at the intersection of the runner (54) and the columnar part, to the square root √S of the cross-sectional area (S) of the columnar part being such that 0.12≤R/√S≤0.96.
