Abstract：

For the problem of failure caused by dimensional changes due to friction losses during the forging process of mold, a mold life prediction method based on key dimensions was proposed. Firstly, based on the principle of gradual failure for mold, the corresponding relationship between the key dimensions of forging mold and forging workpiece and the mold life was constructed. Then, the entire lifecycle business scenario of forging mold was studied, the business logical process for predicting the mold life was provided, and a collection method for key dimensions and actual mold life was proposed. Finally, using key dimensions and actual life, different fitting algorithms were used for mold life prediction. Examples show that the fitting function and the goodness of fitting index obtained from analysis and calculation can used to select specific fitting algorithms for different usage scenarios, so as to realize the accurate prediction of forging mold life.
