Abstract: According to the requirement of injection mold remanufacturing, an evaluation system for mold disassembly was established, and each single factor was quantitatively described. Having studied the evaluation process of the molded parts and researched the correlation and interaction among various factors, based on the correlation matrix of indicators and mathematical graph theory, an evaluation algorithm model of mold disassembly design was established. Taking an injection mold design as an example, the validity of the evaluation algorithm was examined.

Key words: mold, disassembly design, remanufacturing, comprehensive evaluation
