摘　　要：根据汽车拉线接头塑件的工艺特点,设计了该塑件注射模的结构并分析了模具工作过程。该模应用开放式热流道转冷流道侧浇口一点进胶,一模两腔,卧式注射成型;使用NX软件设计了模具分型面,因塑件尺寸较小,空间受限,创新设计了滑块底部带滑块的脱模机构;为了保证滑块底下司筒的安全,设置了顶棍拉杆式先复位机构;利用MoldFlow软件构建了冷却水路,并对模具注射时间、翘曲量等进行仿真模拟,确定理想注射参数以指导生产。According to the process characteristics of the plastic part of an automobile stay wire joint,the structure of the injection mold of the product was designed and the working process was analyzed.In the first mock exam,the open hot runner cooling channel and the side gate of the nozzle are used for one point injection,one mold and two cavities,horizontal injection molding.NX/CAD is used to design the parting surface of the die.Because the size of the plastic part is small and the space is limited,the demoulding mechanism with slider at the bottom of the slider is innovatively designed;In order to ensure the safety of the cylinder under the sliding block,a top rod pull rod type first reset mechanism is set;The cooling water path is constructed by Moldflow,and the injection time and warpage of the mold are simulated to determine the ideal injection parameters to guide the production.
