Abstract Based on die structure analysis, an SIMP based die structure topology optimization model was proposed. An optimal design method for binder part was established, aiming to reduce die weight. Optimization of binder structure of a floor member part of DP590 was studied. Compared with current design, optimally designed binder can reduce 50% weight. And the critical displacement and maximum stress are not affected.
