Considering the low productivity of fixed molded honeycomb mold, an efficient turning molded honeycomb mold is developed. Using TRIZ theory, a technical analysis of fixed molded honeycomb mold is conducted. Through the TRIZ innovation principles of the Spheroidality, combined with the characteristics of the mold, innovative design of the rotary molded honeycomb mold has been made. According on the Pro/MECHANICA analysis platform, by the finite element analysis method, the actual molded honeycomb mold forces, boundary conditions and imposed load are being researched in the view of the molded honeycomb mold for the actual operating conditions. The sensitivity analysis of mold parameters is conducted so as to optimize the structure parameters of mold. Shown by the practical application, the rotary molded mold can improve the productivity significantly.
