Abstract: Design a synchronizer hub forming mold based on the structural characteristics of a certain gearbox synchronizer hub and the principle of equal forming speed and forming rate in powder metallurgy mold design. Design the forming die using variable modulus design method, ropose a design scheme for forming the core rod for the positioning hole, and establish a mold assembly diagram based on the designed mold diagram, and analyze the feasibility of the mold design scheme. Verify the rationality of the forming mold design through mold installation experiments. The results show that the trial production of the gear hub meets the requirements of the automotive company in terms of size, accuracy, and functionality through processes such as shaping and sintering, and successfully achieves cost reduction and efficiency improvement, as well as the development of synchronous gear hub forming molds.

Key words: transmission gear hub; synchronizer; forming mold design
