摘要:

以中心静脉导管挤出成型精度为研究对象,借助Polyflow软件通过反变形技术分析得出精确的口模截面形状及尺寸;通过压缩角、口模成型段长度、间隙角度等参数进行了3因素2水平的正交试验仿真,借助方差分析得到中心静脉导管最佳的挤出模具流道结构参数,并通过生产实际验证了仿真分析结果。结果表明,该挤出模具生产成品率高,对相关类型挤出模具的开发具有一定的借鉴意义。

Abstract:

In this study, the precision of central venous catheter extrusion mold was taken as a research object, and the accurate cross⁃section shape and size of die was obtained from the analysis of a reverse deformation technology with the aid of the Polyflow software. A three⁃factor and two⁃level orthogonal experiment simulation were carried out by using the parameters of compression angle, mold length and clearance angle, and the optimal central venous catheter die runner structure parameters were obtained from the variance analysis. The simulation results were further verified by the actual production. The results indicated that the extrusion die had a high yield and could be used as a reference for the development of related extrusion dies.

Key words: extrusion molding, central venous catheter, Polyflow software, orthogonal test
