Abstract：

Traditional mold replacement modes such as using forklift to coordinate lifting usually takes a lot of time to find the positioning between mold base and equipment, and the mold change efficiency is low. Therefore, according to the specific situation of a 63000 kN press in a forging automatic production line, and in order to avoid the influence of the larger space occupied by the press maintenance platform on the mold hoisting at the same time, a two-stage transmission rapid mold change device was adopted, which saved costs and achieved the purpose of rapid mold change. In addition, the hydraulic clamping mold mechanism was used to lock the mold formwork instead of the traditional form of preloading the mold formwork by T-bolts and nuts, which greatly reduced the work intensity of operator and improved the work efficiency during the process of disassembling and installing the mold formwork. After production verification, the results show that the rapid mold change technology can obviously improve the efficiency of mold change in gear forging automatic production line, and also provides a reference for the mold change scheme on the forging automatic production line of other products.
