采用模流仿真技术对吸油滤清器滤芯骨架的注塑成型工艺进行模拟，针对常规注塑加工过程中易出现的填充、翘曲等缺陷的原因进行分析并提供相应的解决方案。模腔设计采用一模两出的形式，原材料选用30%玻纤增强尼龙树脂，改进方案替滤清器骨架匹配合适的注塑工艺参数。实验结果证明，双浇口、“H”字形流道相比单浇口、“Z”字形流道在注塑机型选择和降低制件翘曲方面更有优势。优化方案中最高注射压力仅为75 MPa，填充时间仅需0.94 s，总体变形为0.35 mm，满足一般产品尺寸偏差要求，且优化效果较为明显。仿真模拟得到填充过程结果良好，且试模样件的外观及变形测量结果均合格，验证了优化参数的可行性。

The mold flow simulation technology was used to simulate the injection molding process of the filter core skeleton of the oil suction filter, and the causes of the defects such as filling and warping were analyzed and the corresponding solutions were provided. The mold cavity designtook the form of having two cavities inside a core, the raw material was selected 30% glass fiber reinforced nylon resin, and the improved scheme matched the appropriate injection molding process parameters for the filter framework. The experimental results showed that double gate and "H" runner had more advantages than single gate and "Z" runner in selecting injection type and reducing warpage of parts. In the optimization scheme, the maximum injection pressure was only 75 MPa, the filling time was only 0.94 s, and the overall deformation was 0.35 mm, which met the requirements of general product size deviation, and the optimization effect was more obvious. The simulation results of the filling process were good, and the appearance and deformation measurement results of the test pieces were qualified, which verified the feasibility of the optimization parameters.
