摘要
基于两种不同的帆船钩注塑料件结构特点,采用镶块成型和斜楔滑块侧抽芯结构,设计出了一模两件四腔的注塑模具。模具浇道采用“S”型布置,且需要绕过侧抽芯分别抵达不同塑料件。采用正交试验法对注塑工艺参数进行了优化,确定了最佳的冷却系统和最优的注塑工艺参数。最优工艺参数为冷却管道直径10 mm,注射时间1.4 s,塑料件顶出温度为95℃。采用最优工艺参数进行实际试模生产,模具结构稳定,产品的精度和质量均符合设计要求。
The structure characteristics of the two sailboat hooks were analyzed by insert block forming and wedge slide block side core pulling structure.The injection mold with four cavities was designed,and two kinds of plastic parts can be produced using this mold.The use of“S”type layout of the sprue needs to bypass the side core to reach different plastic parts.Mold structure and suitable parameters of the process are decided by orthogonal experiment.The suitable cooling system and the optimal injection molding parameters were selected.The optimal process parameters are cooling pipe diameter of 10 mm,injection time of 1.4 s and ejection temperature of plastic parts of 95℃.The optimum process parameters are adopted to test the mold,the mold structure is stable,and the precision and quality of the product meet the design requirements.
