摘要: 针对大型且结构复杂的深色哑光塑料制品在注射成型时表面产生的熔接痕缺陷,通过利用数值模拟软件优化模具浇口数量和排布方式使熔接痕在窄面、非主视面汇合,在模具结构、材料流动性等方面深入研究削弱熔接痕对制品外观的影响,成功获得高质量制品。为免喷涂技术应用于大型复杂结构注塑件提供参考。

Abstract: Aiming at the defects of weld marks generated on the surface of a large-scale and complex-structured dark-colored matte plastic product during injection molding, mold flow software is utilized to optimize the number of mold gates and the arrangement mode to make the weld marks converge on a narrow plane and a non-dominant plane, the influence of weld marks on the appearance of the products was further studied in the aspects of mold structure and material flowability, and high quality products were successfully obtained. Provide reference for the application of spray free technology to large and complex structural injection molded parts.

Key words: Air conditioning, Spray free, Numerical simulation, Mold structure, Material fluidity
