Claim Text:
1. A casting machine for fabrication of precast concrete structural members, comprising: side walls including integrally formed end dams which are pivotally movable from an open position to a closed position; and a bottom casting surface, which includes pivotable bottom surfaces which rotate on bottom surface pivots to a vertical position and to a horizontal position, said bottom casting surface, and said side walls with integrally formed end dams serving to form a self-releasing mold surrounding a cavity when said side walls with integrally formed end dams are in said closed position, said self-releasing mold being configured to contain wet concrete which is pumped into said cavity, said side walls with integrally formed end dams, being automatically movable to an open position when said concrete has solidified so that a precast concrete structural member is automatically released from said self-releasing mold; and a removable bottom core which completely supports a precast structural member from within when said side walls and said end dams are moved to said open position.
