The die brace of claim 1, wherein the back plate is the back plate of a movable die core. 3. The die brace of claim 1, wherein the collar is substantially cylindrical in shape and includes an axial thru-bore for passage of a die tie bar. 4. The die brace of claim 3, wherein the collar is adapted to securely grip a tie bar to which it is installed. 5. The die brace of claim 3, wherein the collar is adapted to float on a tie bar to which it is installed. 6. The die brace of claim 3, wherein the collar is of split design. 7. The die brace of claim 6, wherein the collar is divided substantially along the longitudinal centerline thereof into two halves. 8. The die brace of claim 7, wherein the collar halves are adapted to encircle a die tie bar and to be secured to one another with threaded fasteners. 9. The die brace of claim 1, wherein the back plate bracket element is substantially L-shaped and adapted to overlie a portion of a front and top face of a movable die core back plate. 10. The die brace of claim 1, wherein the bracing leg extends between the collar and the back plate bracket element at an angle of less than 90° as measured from either a front face of a movable die core back plate or a longitudinal axis of a die tie bar when the die brace is installed thereto. 11. The die brace of claim 10, wherein the angle is approximately 45°. 12. The die brace of claim 1, wherein the die tie bar and movable die core back plate are components of a metal casting die. 13. A die brace for installation between a movable die core back plate and an associated die tie bar of a metal casting die, the brace comprising: a collar adapted to fit over and grip the die tie bar;a back plate bracket element adapted for affixation to the movable die core back plate; andan integral bracing leg that extends between the collar and the back plate bracket element at a fixed angle of less than 90 degrees as measured from either a front face of the movable die core back plate or a longitudinal axis of the die tie bar when the die brace is installed thereto;wherein the angle of the bracing leg with respect to the collar and the back plate bracket element remains fixed, such that the die brace is operative to maintain a proper orientation and relationship between the tie bar and back plate during movement of a movable die core associated with the movable die core back plate. 14. The die brace of claim 13, wherein the collar is substantially cylindrical in shape and includes an axial thru-bore for passage of the tie bar. 15. The die brace of claim 14, wherein the collar is of split design. 16. The die brace of claim 15, wherein the collar is divided substantially along the longitudinal centerline thereof into two halves. 17. The die brace of claim 15, wherein the collar halves are arranged to encircle the tie bar and adapted to be secured to one another with threaded fasteners. 18. The die brace of claim 13, wherein the back plate bracket element is substantially L-shaped and adapted to overlie a portion of the front and top faces of the movable die core back plate. 19. The die brace of claim 13, wherein the bracing leg extends between the collar and the back plate bracket element at an angle of approximately 45° .
