CAST-IN STRUCTURE AND CAST-IN MOLD FOR VEHICLE COMPONENT

摘要

An object of the present invention is to surely provide a projection of burr by forming an appropriate gap needed to set a cast-in member to a cast-in mold, and by completely closing the gap when the cast-in mold is clamped, and to correct a cast-in positioning (axis mating) to a die-cast component by a clamping operation of the die-cast mold, regardless of a dimensional precision of the cast-in member upon a manufacture.;A steel plate cast-in member 2, which is wrapped cast except for a bonding portion 2b to a steel plate bonding member 3 upon molding a die-cast component 1, has a mold contact portion 4 at a boundary between a cast-in portion 2a wrapped cast with a die-cast component 1 and the bonding portion 2b. When a cast-in mold A is clamped, the mold contact portion 4 is brought into intimate butting contact with the cast-in mold A, whereby a gap S between the cast-in member 2 and the cast-in mold A, i.e., a cavity a, is closed. Thus, a projection of burr is prevented.

主权项

1. A cast-in mold for a cast-in member, the cast-in mold being configured to cast-in a steel plate cast-in member to a die-cast component by setting a cast-in portion of the steel plate cast-in member into a cavity except for a bonding portion to be bonded to a steel plate bonding member, wherein
the cast-in mold includes a butting portion that is brought into intimate butting contact with a mold contact portion upon mold clamping, the mold contact portion being formed on both surfaces of the cast-in member at a boundary between the cast-in portion and the bonding portion of the cast-in member.
