The purpose of the present invention is to reliably prevent burr protrusions by appropriately taking the necessary gap in order to set a cast-in member in a cast-in mold and completely closing the gap when the cast-in mold is clamped, and to correct, regardless of manufacturing dimensional accuracy of the cast-in member, positioning (centering) of the cast-in relative to the die-cast component through the action of clamping the die-cast mold. During formation of the die-cast component (1), a steel plate cast-in member (2), which is cast in while leaving the side of the joined section (2b) joined with a steel plate joining member (3), is provided with a mold contact portion (4) in the border section between the side of the cast-in section (2a) cast into the die-cast component (1) and the side of the joined section (2b), and, by pressing into close contact when the cast-in mold (A) is clamped, the cavity (a), i.e., the gap (S) between the cast-in member (2) and the cast-in mold (A), is sealed and burr protrusions are prevented. |
