As for the long rod die forgings of small and medium size, the conventional process is machined by forging equipment and trimming devices simultaneously. Using a special multistation traction hook combined die overall structure, the process manner of using single friction press doing die forging and trimming (also flexible, reverse) was solved and the one mold for multipurpose application was realized. The structural features in the mold design, structure and layout of the module and work projects were discussed. The modules and templates adopted the mosaic connections, the forging mold cavity was in the middle of the module and the trimming molds were located on both sides. The mold has the features of flexible structure, easy operation, low production cost and high efficiency. It is proved that the product quality is stable and can be widely used.
