摘　　要：针对乳液泵弧向出液按头在注射成型时强制脱模可能带来的不良品率过高的问题,设计了带有旋转侧抽芯机构的乳液泵弧向出液按头注塑模。该侧抽芯机构由气缸带动连杆进行圆弧旋转侧抽芯,减少了模具制造上的困难。浇注系统选用潜伏式浇口,能够实现凝料自动脱落。脉冲式冷却系统能够使模具达到快速均匀的冷却效果,极大地提高了生产效率。According to the problems that qualified rate is too low when arc outlet head of emulsion pump was forced to demould in injection molding process, the injection mold of the arc outlet head with rotary side core-pulling mechanism was designed. The arc rotary side core-pulling motion is realized through cylinder driving the connecting rod and it can reduce the difficulty of manufacturing the mold. Using submarine gate can realize pulling out freezing material. The selective impulsetype cooling system can achieve the uniform cooling effect when the mold is cooled with the system and improves productivity enormously.
