澆道比
英文
runner ratio-
The cross section area of the internal sprue of the die casting dies designed should be of proper value, and matches perfectly the fill speed, the fill time and injection pressure in case that the die casting dies fail in the design
設計壓鑄模時應當確定恰當的內澆道截面積，並使之與充填速度、充填時間和壓射比壓保持較好的匹配，以防止壓鑄模設計的失敗。The cross - section area of the internal sprue, the fill speed, the fill time and injection pressure are important die casting technology parameters
摘要內澆道截面積、充填速度、充填時間和壓射比壓都是重要的壓鑄工藝參數。The research showed that basin is the more important feeding resource than runner in runner type gating system in lost wax casting. therefore, on the basis of the basin as feeding resource, runner and ingate as feeding channel, a new design method for runner type pouring and feeding system in investment casting was developed. the corresponding feeding mathematical pattern and allowable total weight listed for casting cluster with different basin were established after analyzing the practical feeding of basin and the calculating process for design was described in detail
在熔模鑄造橫澆道型澆注系統中，澆口杯是比橫澆道更為重要的補縮源，因此在立足於澆口杯為補縮源、橫澆道和內澆道為澆注補縮通道的基礎上，開發了適用於熔模鑄造橫澆道型澆注補縮系統設計的新設計方法，在詳細分析了澆口杯的實際補縮情況后，建立了相應的數學補縮模式和不同澆口杯的鑄件組許用鑄件總質量表，並具體介紹了設計計算過程。Find the law of the influence from the injection pressure to the filling time and the cavity pressure and make certain of the best filling time, injection time and injection pressure. though the analysis of the flowing velocity and pressure spread of the key position element in the injection parts in different gate position, we forecast the injection parts quality and the possibility injection flaw and its position, optimize the gate position. in this paper, though the research of analogue of the runner system of metal - powder injection molding and the process of injection molding, we get the law of how the injection parameter influence the injection process
在相同的注射條件下，通過分析喂料在不同直徑和長度流道中的流動規律，得到了喂料在流道中的速度場、壓力場和溫度場，找到了流道長徑比的合理取值范圍，並得出通過改變流道設計可實現對現有設備資源充分利用的結論；給出了不同注射壓力下，型腔壓力與充模時間關系曲線和喂料熔體平均充填速度與充模時間關系的曲線，得到了注射壓力對充填時間和型腔壓力的影響規律，確定了最佳的充模時間、注射時間和注射壓力；通過分析採用不同位置澆口注射時注射件關鍵位置單元的流動速度和壓力分佈，預測了注射件的成形質量，或可能產生的注射缺陷及位置，優化了澆口設置。The max. temperature, cold runner result shows the max. temperature across the cold runner temperature profile calculated at the end of cooling time
冷卻結束時，冷澆道斷面上最高溫度分佈情況（與頂出溫度相比，判斷此時是否頂出） 。分享友人
