Clonal Selection Algorithm Based Optimization of Heating Channels for Variotherm Injection Mold

Integration of approximate model and clonal selection algorithm (CSA) is considered as an effective way to solve complicated optimization design problems in engineering field. The principles of approximate model and of clonal selection algorithm were presented in this paper. A variotherm temperature injection mold used to produce a large-size liquid crystal display (LCD) TV panel was demonstrated and an approximate model for optimizing the layout of heating channels of the mold was established. The clonal selection algorithm program was coded according to its principle in order to solve the established approximate model. The layout of the heating channels was optimized and the optimal solutions were obtained. Finite element simulation and industrial injection production indicated that the integration of the approximate model and clone selection algorithm used in this paper to optimize the layout of the heating channels for the injection mold was very effective.
