ALIA 分什麼要分析 ? 模溫的影響 Why analyse? Die temperature affects ?鑄件品質 Casting Quality ?模具壽命 Die life ?生產效率 Production rate Castec AUSTRALIA 實驗 :利用 CASTHERM研究對下面兩項的影響 : An experiment: use CASTHERM to study the effect of ?水流率 water flow rate and ?冷卻距離對模面溫度 cooling distance on die surface temperature 距離 distance Castec AUSTRALIA 水流率 amp。冷卻距離的效益 Effect of water flow rate amp。 cooling distance distance 溫度 Temperature 水流率 Flow rate Castec AUSTRALIA 模具冷卻 amp。加熱設計的方法 Die Cooling/Heating Design Procedures ?大姆指法 (經驗法 ) Rule of thumb experience based ?Castherm法 CASTHERM procedure Castec AUSTRALIA CASTHERM方法 CASTHERM Procedure 水管定位 (Locate channel) 計算溫度 Calculate temperature 可接受 (Acceptable ?) 修改 (Modify) 開模 (Build die) Castec AUSTRALIA 2D分析 CASTHERM 2D analysis CASTHERM Castec AUSTRALIA 為何不是 3D? Why not 3D? ?模具圖仍未做到 3D 3D die drawings are not readily available ?只能鑽直的孔 Drilled holes are straight ?導熱區(qū)的概念引入已考慮 3D:體積 amp。表面積 Thermal zone concept takes into account 3D entities volume amp。 surface area ?根據經驗 :五個剖面就足夠 Experience suggests up to 5 die sections are sufficient Castec AUSTRALIA 樣品 1: 2D已足夠 Sample 1: 2D sections are sufficient Castec AUSTRALIA 樣品 1: 2D已足夠 Sample 2: 2D sections are sufficient Castec AUSTRALIA 樣品 1: 2D已足夠 Sample 3: Three 2D sections are sufficien
