摘　　要：分析了出水弯接头塑件的结构及成型工艺,针对塑件材料性能、内部垂直管道及侧面安装孔,研究了一模二件对称分布的注塑型腔模具结构,设计了包含弹簧辅助分型抽芯的三套侧向分型机构于同一模具上方案,采用了冷料井为顶出位和确保开合模行程有效的结构。并设计了模具的盘式浇注系统、组合式的型腔与开型芯部件、斜导柱式侧向分型抽芯机构、导向机构、复位及顶出机构、冷却与排气系统等。实践结果表明:模具设计方案合理、结构紧凑、动作可靠。It analyzed the structure and forming process of plastic parts of the pump outlet＇s curved pipe and studied the injection cavity mould mode structure of symmetric distribution of＂one mould two plastic parts＂according to the material property,the internal vertical pipe of plastic parts as well as the side mounting hole.The scheme of combining three side parting mechanisms were designed including the spring aided parting core-pulling as one,adopting the cold slug well as the ejection and making sure the efficient structure of mould open-close stroke.The disc feed system,molding parts,combined cavity and open cores parts,bevel lead side parting core pulling mechanism,guiding mechanism and reset ejector plate assembly as well as cooling exhaust system were designed.The results of practice show that the rational design scheme of mould has compact structure and reliable action.
