| 中文摘要 | 本文以「製圖圓圈板」薄件產品為探討案例,使用奇美公司之ABS-PA716材料,籍由C-MOLD2000模流分析軟體,考量四種不同澆口位置之設計,配合流道與冷卻管路之配置,模擬射出成型中的充填、保壓、冷卻與收縮翹曲變形分析。從分析結果中,比較流動平衡、充填結束時之溫差變化、射出壓力與厚度方向之翹曲變形(即表面平整度),了解不同澆口位置設計對於「製圖圓圈板」翹曲變形之影響。 依據模流分析結果可知,由側邊雙澆口位置之進澆方式的流道長度最長,所需射壓最高為97.5Mpa,而C-MOLD單一澆口位置最佳化分析之進澆方式流道長度最短,流動平衡效果最好,所需射壓最低為64.1Mpa。但是由於成型品幾何造型之因素,C-MOLD單一澆口位置最佳化分析之進澆位置的邊緣保壓效果比較差,所以翹曲情形最大(翹曲變形量為0.025mm)。 在實際成型品量測時,以C-MOLD單一澆口位置最佳化分析之進澆位置的翹曲量最大(翹曲變形量為0.221mm),亦即產品之平整度最差,而以側邊雙澆口位置之成型品量測之翹曲變形量最少(翹曲變形量為0.096mm),亦即此種澆口位置設計之進澆方式的平整度效果最好。 |
| 英文摘要 | This paper used the C-MOLD® 2000 to simulate the mold flow of sketch circle plate by considering four types gate location. In the C-MOLD® 2000, the Chi-Mei® ABS PA-716 material was used to simulate the filling process、the packing/holding process、the cooling process and the shrinkage/warpage process. After finishing the simulations ' we compared the various analysis results including the pressure at entrance, the states of flow balance and the warpage at normal direction with each type gate location and then referred the analysis results to manufacture sketch circle plate mold. According to the mold flow simulation results, the type of two gates align at one side has the maximum injection pressure due to the longest runner and the type of one gate located at the center position has the minimum injection pressure due to the shortest runner but at the same time it has the maximum warpage, which correspondence with experimental measurements. |
