| 中文摘要: |
| 目的 研究纸浆模塑制品分体式成形模具的开孔问题， 以保证制品厚度均匀、 外观美观。方法 通过分析纸模制品成形过程中滤液流动的能量损失， 建立滤液在分体式模具内的出流过程的能量方程， 以研究模具特定部位间应具有的开孔率关系。结果 建立了模具不同部位之间的开孔率关系式， 并研究了模具各部位的布孔方法。结论 为保证纸模制品壁厚一致， 模具不同部位间的开孔率需满足一定关系；模腔底面宜采用60°错排的布孔方式， 而直立侧壁可划分成若干连续的单位开孔区， 采用非均匀性布孔方式。 |
| 英文摘要: |
| The aim of the study was to research the opening problem of split type suck-filtration mold for molded pulp packaging products, in order to ensure that the product thickness is uniform, and the appearance was good. Through analyzing the energy loss of the filtrate flowing in the molding process of the molded pulp packaging products, the energy equation of filtrate flowing process in the split type mold was established, to research the relationship of the opening ratio between the specific parts of the mold. Equation for the opening ratio relationship between different parts of the mold was established, and the opening arrangement method in different parts of the mold was studied. In order to ensure uniform thickness of the product, the opening ratio between different parts of the mold need to meet a certain relationship; Cavity bottom should use 60° staggered opening arrangement method, and the vertical wall can be divided into several continuous unit opening areas, using heterogeneous opening arrangement method. |
