Abstract：The mold design and material selection for the high-voltage connector socket housing directly affect the reliability of the equipment. This paper proposes a mold design scheme based on carbon fiber composite materials. By optimizing the gating system with a bul-horn latent gate and combining a surrounding cooling circuit with a well-type cooling circuit，the molding efficiency is significantly improved. Experimental results indicate that the optimized pouring time is reduced to 7.22s ，with a melt shear rate of 4×105s-1 and a filling rate exceeding 98% . Moreover，the corrosion potential of the carbon fiber composite material remains stable at -0.11V ，while its tensile strength （209MPa， ）and flexural strength（268 MPa ） surpass those of traditional metal materials. When the carbon fiber content is increased to 30% ， the warpage of the plastic part at the vertical and parallel cross-sections is reduced to（204号 0.1414mm and 0.1413mm ，respectively，and the service life of the mold is extended to 8 years.This study provides a technical reference for the design of injection molds for highprecision socket housings.
