Molding tool with biomimetic conformal venting passageways

The present invention provides a molding tool with biomimetic conformal venting passageways. The method of forming a molding tool includes performing a computer aided engineering (CAE) analysis on a molding tool design. The CAE analysis predicts flow of injection molded material and a location of gas entrapment within a molding recess of the molding tool design. At least one venting design constraint is applied to the molding tool design as a function of the gas entrapment location. Also, a biomimetic shaped passageway for venting gas away from the gas entrapment location is selected from a plurality of biomimetic shaped passageways. A computational fluid dynamic (CFD) CAE analysis of the molding tool design with the selected biomimetic shaped passageway is performed and modifications of the selected biomimetic shaped passageway are CFD CAE analyzed until a final biomimetic shaped passageway is determined and a molding tool with the final biomimetic shaped passageway is formed. 本公开提供了"具有仿生共形排气通道的成型工具"。一种形成成型工
