Abstract： This paper mainly solves the multi-objective optimization design problem of mold hydraulic opening and closing system under the background of intelligent manufacturing. Aiming at the key performance indexes of hydraulic system，a multi-objective optimization model is constructed，and an improved particle swarm optimization （PSO） algorithm is introduced to improve its global search ability and convergence speed. In the study，the experimental platform was built and tested to verify the effectiveness of the optimization algorithm. Experiments show that compared with the traditional design method，the energy consumption of the optimized system is reduced by 30% （from 2.0kW⋅h to 1.4kW⋅h ， the opening and closing time is shortened by 30.6% （from 7.2 s to 5.0s ），and the position error is reduced by 60% （from 1.0 mm to 0.4mm ）.In addition，the convergence speed of the improved PSO is 50% higher than that of the standard PSO，and the average fitness value is reduced from O. 28 to O. 23，which is obviously better than other algorithms. To some extent，this study provides theoretical support for the high-performance design of mold hydraulic opening and closing system，and promotes the application of intelligent manufacturing technology in hydraulic field.
