本研究是利用模流分析軟體 Moldflow進行分析,CAE的技術即可在設計階段先行發現並解決射出成形時可能遭遇到的問題,事先預知製作過程中所可能發生的情況及成品的品質好壞,可快速檢驗零件及模具的設計是否合宜,針對問題進行修改,並對成形參數進行最佳化,其中探討的成型參數為模具溫度、融膠溫度、冷卻時間、射出壓力、保壓壓力、保壓時間。
分別對進澆點數量進行探討,在能有效進行產品的射出下找出最佳進澆點位置及進澆點數量,並對澆流道進行平衡的設計。建立更有效的冷卻系統,能更迅速均勻的冷卻產品,並維持塑件尺寸精度和穩定性,降低產品的翹曲收縮變形,以減少產品開發及模具修改等成本考量,進而順利達成量產與降低成本提升競爭力。
This paper utilizes the Moldflow Plastics Insight software to analyze mold flow of pallet and study the effect of number of pouring mouth on product formation, including that of finishing time, flowing mark situation and temperature profile. Size, flowing mark and level of temperature will influence the product density, appearance, toughness of the products and stabilization degree. In design stage, mold-flow analysis was used the taguchi method to find out the optimal processing conditions were evaluated with the analysis of mold temperature, melt temperature, cooling time, injection pressure, packing pressure, packing time, the packing pressure etc. Mold-flow analysis was used for decreasing the product cost effectively. On the other hand, it achieves the purpose of mass production, reduce the cost and promote the competitive ability of mold maker.
