In order to further improve the manufacturing sustainability aiming at low carbon, it is necessary to design and optimize the low carbon process of the composite mold of Moldless .
Therefore, according to the structural characteristics of the mold, the forming methods and materials of the composite mold are discussed in this chapter. Secondly, through the analysis of the characteristics of the process parameters of the composite mold, the process parameters of the composite mold are divided into three types: the independent process parameters of the composite mold, the correction process parameters of the composite mold and the coupling process parameters of the composite mold. The low-carbon optimization design of the coupling process parameters of the composite mold is carried out by using particle swarm optimization algorithm, So as to improve the sustainable design system of compound mold forming of Moldless sand casting.
Firstly, the forming method and material selection of composite mold are analyzed, and the forming method and molding sand material suitable for specific mold structure are discussed. Secondly, the process parameters of composite mold are analyzed and defined. Finally, taking the coupling process parameters of composite mold as the optimization object, a design scheme for low-carbon optimization of composite mold is proposed.
