Abstract：This article focuses on the issues of poor molding efficiency and consistency of sports injury protection equipment， and conducts research on collaborative molding technology for multi cavity molds. By constructing a heat conduction model and pressure dynamics model for a multi cavity mold system， a collaborative control strategy that integrates proportional-integral-derivative （PID） control and fuzzy adaptive mechanism is proposed，and a scheduling algorithm based on multi-objective optimization is also designed. On the experimental platform，a four cavity mold system was used to test the formation of knee pads made of ethylene-vinyl acetate Copolymer （EVA） material. The results showed that under the action of adaptive fuzzy control strategy， the temperature consistency of each cavity was significantly improved， the temperature difference was controlled within ±0.9°C ，the pressure standard deviation was reduced to 0.01MPa ，the thickness deviation was reduced to ± 0.11mm ，the average number of bubbles was O.4 per piece，and the molding cycle was shortened to 31.2min . The study found that the proposed collaborative control method effectively improves the molding quality and system stability.
