摘要
Abstract
According to the design requirements of a straight pipe mouth double shrink water chamber in the heat-ex-change system,a detailed process plan was proposed to form the part using a thermoplastic composite based on the PA66 matrix and 30 wt% glass fiber(GF).This plan included the plastic component characteristic analysis,structural design,working principle,and pre-deformation technology of products.The key technologies for the design of the water cham-ber and the pre-deformation of products were studied.Through multiple verifications,the optimal mathematical model for the nozzle water chamber product was designed,and corresponding injection molds were developed.The research re-sults indicated that the structural design of the double shrink Ke slider achieved a significant improvement in the mold space utilization and plastic forming quality.This design makes the mold space more compact and improves the produc-tion efficiency.Meanwhile,the optimized structure reduces the molding defects of the plastic parts,ensuring the stability of product quality.By using the PA66/30 wt% GF composite and mold design scheme,the original metal parts were re-placed by the plastic parts,which greatly reduced the processing and material costs.Such a lightweight design not only reduces the weight of the entire vehicle,but also improves the vehicle's endurance.This study provides an effective ap-proach for the technological development and engineering practice in related fields.关键词
