Damping insert locator for a rotor core tool and a brake rotor employing the same

A rotor core tool for casting a brake rotor for a motor vehicle, the rotor core tool comprising:

• a rotor core tool base comprising a circumferential boundary wall that extends substantially perpendicularly away from a side boundary wall that forms a bottom portion of the rotor core tool base, the circumferential boundary wall being spaced apart from an axis of the rotor core tool base by a diameter of the brake rotor;
• at least one cable comprising a plurality of wires, each of the plurality of wires having a surface in sliding contact with surfaces of adjacent wires of the plurality of wires, wherein the at least one cable is concentric with the circumferential boundary about the axis;
• an outer annular ring disposed at the side boundary wall and concentric with the circumferential boundary about the axis;
• an inner annular ring disposed at the side boundary wall and concentric with the circumferential boundary about the axis, the inner annular ring having a smaller diameter than the outer annular ring;
• and
• a plurality of damping insert locators extending radially away from the axis such that a first instance of the damping insert locators constrains movement of the at least one cable in a first direction, and a second instance of the damping insert locators constrains movement of the at least one cable in a second direction, opposite the first direction.
