E1 Optimization Design of Cooling Channel of Block Laminated Mold by using Genetic Algorithm(Other manufacturing-related technologies)

Abstract

This study discusses a method for the automatic design of injection-mold cooling channels using genetic algorithms (GA), the finite element method (FEM), and an evaluation function based on unsteady state heat transfer and linear static deformation. The uniformity of cooling and the deformation effect of the automatically designed cooling channel in the injection mold were examined through case studies based on numerical analysis. The genetic algorithm was applied in the following steps: generation of finite elements of individuals expressing different cooling channel shapes, the definition of the fitness function to evaluate individuals, the genetic operation for individuals, and modification to the automatically generated cooling channel shape. Finally, the automatically generated shape of the cooling channel is discussed.
