  • Computerized system for lost foam casting process using rapid tooling set-up
    Patent number: 5796620
    Abstract: A casting system is disclosed which utilizes conventional CAD/CAM software to automatically position the rods of a pin mold to replicate, by the rod end surfaces, the surface contours of an object drawn on a CAD machine when the object is cast in the pin mold. The system modifies the data base to account for the plastic liner and liner variations to permit production of styrofoam cores in the Lost Foam Casting process while the pin mold incorporates a rod and hole configuration in the guide plates which permits automatic positioning and frictional locking of the rods in the pin mold.
