摘要
在带有90°弯管的移位器底座注塑模具设计中,提出一种适用于弯管抽芯的双滑块弯销内抽芯机构。通过从弯管弯曲段主型芯中分割出滑块型芯先进行内抽芯,避免了脱模时带倒扣的弯管与主型芯发生摩擦。通过在滑块型芯的弯销内抽芯机构中引进辅助滑块,替代传统的注塑模具辅助分型面结构,可实现滑块型芯任意角度的内抽芯,从而简化了注塑模具的结构,提高了模具抽芯机构的工作稳定性。
In the injection mold design process of the shifter pedestal with 90° bending pipe, a double sliders Iormcltorm dowel inside core-pulling mechanism suitable for the bending pipe core-pulling was put forward. Through separating slider core from main bending core of the bending pipe for doing inside core-pulling firstly, the interference of the main core and the bending pipe with undercut is avoided when demolding. Through adding auxiliary slider into the forniciform dowel inside core-pulling mechanism of the slider core for replacing traditional auxiliary parting surface of injection mold, the inside core-pulling at any angle of the slider core can be realized. The inside core-pulling mechanism can reduce the complexity of the mold structure and enhance the core- pulling work stability.
