The solid-state forming technology of thermoplastic parts is a new production process developed in recent years. This article uses the Plastic Advisor module to simulate the filling of plastic gears and optimize the process parameters. By setting different number of gates, mold temperature and injection temperature, the injection pressure, weld line distribution, air pocket distribution and melt temperature distribution are analyzed, and the best gate number, position and corresponding plastic gear molding are determined. Process parameters to reduce injection molding defects and improve product quality. Combining the simulation analysis results to design the three-dimensional injection mold of the plastic gear, the parametric design of the mold is realized, and the design efficiency of the injection mold is greatly improved.
