Research on the design and material selection of the mold for the housing of electrical equipment
摘要
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 bull-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 7.22 s,with a melt shear rate of 4×105 s-1 and a filling rate exceeding 98％.Moreover,the corrosion potential of the carbon fiber composite material remains stable at-0.11 V,while its tensile strength(209 MPa)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 0.1414 mm and 0.1413 mm,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 high-precision socket housings.This study provides technical reference forthe design of high-precision injection molds for socket housings.关键词
