| 中文摘要: |
| 为解决医用药瓶吹塑过程中塑件壁厚不均的问题，课题组利用ANSYS软件中的POLYFLOW模块对其进行了成型模拟。通过设计L9(33)正交实验表，研究不同吹胀压力、吹胀时间及模具运动速度对塑件壁厚的影响，从而制定出最佳的工艺参数；再对最佳的工艺参数进行模拟验证，最后通过实际生产验证模拟的结果正确与否。结果表明：吹胀时间8 s、吹胀压力为0.1 MPa和模具运动速度为0.9 m/s时，得到的产品质量较好，壁厚较为均匀。通过该研究为吹塑制件的壁厚控制提供了参考，在一定程度上降低了生产成本。 |

| In order to solve the problem of uneven wall thickness of blown plastic parts in the process of blow molding, the wall thickness was simulated by using the POLYFLOW module in the ANSYS software. By designing L9(33) orthogonal experimental table, the effects of different blowing pressure, blowing time and mold movement on the wall thickness of plastic parts were studied, and the optimal process parameters were worked out. Then the simulation of the best process parameters was verified, and the simulation was verified through the actual production. The results show that the product quality is better and the wall thickness is more uniform when the expansion time is 8 s, the blowing pressure is 01 MPa, and the mold velocity is 09 m/s. This research can provide effective guidance for the wall thickness of blown plastic parts and reduce the production cost to some extent. |
