To protect the phenomenon that plastic parts are often left in the half of the fixed mold when mold is being opened, this paper put forward detailed preventive measures and resolved methods from the injection process to the design and manufacture of the mold. 针对注塑模具中常出现的塑件留在定模上的现象,从注塑工艺和模具设计与制造两方面提出了具体的预防措施和解决办法。
Dual-layer cycle cooling is applied for fixed mold cavity insert of mold, and compatible septa cycle cooling is used on the movable core insert, the mold after injection forming can be cooled sufficiently, the forming cycle is shorten and the products quality get improved as well. 模具定模型腔镶件采用了双层循环冷却方式,动模型芯镶件采用了并行隔片循环冷却方式,模具注射成型后能充分冷却,既缩短了成型周期,又提高了产品质量。
By applying working principle of antecedence reposition mechanism in mold structure, ejector mechanism is set in one side of fixed mold to eject injection formed plastic parts, which satisfies surface quality requirements of products. 模具结构利用先复位机构的工作机理,实现在定模一侧设置顶出机构顶出注射成型后的塑件,满足了产品的外观质量要求。
Analysis on Fracture Failure of Fixed Bolt in Mold of Caster 连铸机结晶器铜板与备板固定螺栓开焊断裂失效分析
Based on this factors, by the complex method, the three important parameters ( fixed mold temperature, packing time, packing pressure) are optimized to further reduce the amount of warpage of plastic parts. 然后,利用复合形法对影响翘曲变形量最大的三个因素(定模温度、保压时间、保压压力)进行优化设计,进一步减小塑件翘曲变形量。
The overall function was decomposed into three major parts: lateral-rolling component, tensile system and fixed mold table. 将机床整体功能分解为三大模块:侧向滚压功能组件、拉伸系统和固定模具工作台。
