ABSTRACT:
A new apparatus for casting dental prosthesis has been proposed, comprising a ring-placing section onto which plural rings are to be placed, a crucible holder for holding plural cylindrical crucibles, a burning unit with a furnace, a casting unit and a conveyer for conveying the ring or the crucible. The lifting state of the burning unit includes a base capable of rotating around a substantially horizontal axis, an orientation-maintaining mechanism for maintaining the base substantially horizontal and an orientation-changing mechanism for exerting an external force onto the base. The conveyer performs a position-correcting motion for correcting the position of the ring by lowering the gripper. The apparatus provides a management code to each crucible for preventing troubles or delay of work caused by the breaking of crucibles due to the aging.
