Modeling Design of Injection Molding Machines Based on Extension Semantic Analysis

To address the problem of insufficient embodiment of form image features in injection molding machine design, a modeling design method of injection molding machine based on extension semantic analysis was proposed. Firstly, the focus group method was used to obtain the image features of the injection molding machine and analyze the form image characteristics of the injection molding machine; Secondly, the extension features of the extracted form image features were evaluated by using the questionnaire survey, and the extension design interval of each form image feature was obtained; Thirdly, the graphic analysis was carried out for the form image features with large extension design interval, the modeling image features were transformed into graphic semantics by using graphic thinking, and the graphic interpretation semantic database was constructed by combining the extension transformation method. Finally, the form image features were applied to the molding design of injection molding machine in the form of graphics, and the optimal design scheme was selected by combining with the fuzzy comprehensive evaluation method, which verifies the feasibility of this method in the molding design of injection molding machine. The results show that the extension semantic analysis can effectively extract and utilize the form image feature elements, and provide a detailed and efficiently method for the modeling design of injection molding machine.
