To solve the problem of complex calculation process of plasticizing energy consumption and various related design parameters and process parameters in high energy consumption injection molding equipment,a convenient analysis method of plasticizing energy consumption based on process excavation was proposed.According to the plasticizing molding method and plasticizing energy consumption analysis process,the flow model of plasticizing energy consumption analysis was constructed,and the calculating flow footprints extracted were mined with improved process mining algorithm based on the model,so that the new energy consumption analysis and calculation workflow-net(WF-net)was formed.The convenient energy consumption analysis and calculation were realized by analyzing the relationship between design elements of WF-net and calculating the plasticizing energy consumption of injection molding equipment.The proposed method was applied in the analysis and calculation processing of plasticizing energy consumption of XS-Z60 injection molding equipment manufactured by an injection molding machine manufacturer.As a result,the process of the energy analysis and calculation was simplified,and the efficiency of the energy analysis and calculation was improved.
