A sweep core die device for a throttle body, or other part, has a cover insert and an ej insert that engage leaving voids therein, a ram component entering the voids, and cores connected to the ram component by ball joints and other components for simultaneous movement in several axes within the voids. The cores are mirror image and connect to one end of a mount. The other end of the mount pivotally connects to the ej insert. A shaft pivotally connects to each mount and to a clamp outwardly from the inserts. The clamp moves relative to the two inserts, moves the shafts, and thus rotates the cores inwardly and outwardly through the voids. The cores have the internal shape of the passage through each horn of a finished throttle body or other part. The cores produce passages so fuel attains laminar flow within the part. |

1. A device for making a part having internal laminar flow of fluid there through, said device comprising:
two mutually engaging inserts, said inserts cooperating and having mutual voids therein, said inserts adapted to make the part; a ram assembly operatively entering said inserts and partially occupying said mutual voids; said inserts including an ej insert being generally rectangular and having a front, an opposite back, a right side, an opposite left side, a bottom and an opposite top, and a cover insert being generally rectangular and having a front, an opposite back, a right side, an opposite left side, a bottom and an opposite top wherein said bottom of said cover insert mates with said top of said ej insert; and, wherein said ram assembly, said ej insert and said cover insert cooperate and are adapted to make the part hollow; said bottom of said ej insert being generally planar and flat; said top of said ej insert having two haunches therein, said haunches extend generally away from said top and towards said left side and said right side respectively, wherein said ram assembly operates upon said haunches. |
