Abstract
An apparatus and method for removing tie bars from a die casting machine. The apparatus and method involves utilizing gearing attached to the tie bar nut whereby the nut is held captive, but is capable of being rotated by an auxiliary drive unit. Further, by utilizing the existing die casting machine functions, it is possible to remove the tie bar from the machine so that the die can be removed and a new die inserted into the die casting machine. By reversing the process the tie bar can now be reinserted into its operating position in the machine and the locking nut rotated to its proper position and locked up.
