| 中文摘要: |
| 目的 开发一种可生产无脱模斜度纸浆模塑包装制品的成形模具。方法 以一种纸浆模塑酒盒底托制品为例， 通过分析该制品的结构及成形工艺， 研究模具工作尺寸计算方法、 制品脱模过程和成形模具分体结构。结果 基于纸模制品成形工艺及模具设计要求， 设计了一种分体式吸滤成形模具。结论 设计分体模具必须考虑纸模制品的平均收缩率及其波动、 模具制造误差和装配误差等因素， 成形上模应沿对角线拆分成对称的两部分， 成形下模应设计能准确定位上模的凸缘结构。 |
| 英文摘要: |
| This experiment developed a kind of mold which can be used to produce the special molded pulp packaging products without draft angle. The molded pulp wine-box base was taken as an example. By analyzing the structure and molding process of the product, the calculation method of mold working dimensions, demolding process and split structure of the mold were studied. Based on the requirement of molding process and mold design of pulp molded products, a split type suck-filtration mold was designed. When designing the split mold， the factors must be considered such as the average shrinkage and its fluctuation, mold manufacturing and assembly errors, etc. The upper mold should be split into two symmetrical parts along the diagonal and the lower mold needed a flange structure to locate the upper mold accurately. |
