【正文】 C2100HF. For analysis is prepared mould finite element mesh model. Start model dimensions is determined conventional calculation. In next step is performed runner optimization analysis, to reduce volume and weight of runner system. Determining dimension of runner system by nomogramsThis method belongs to conventional way of puting. Input data for determining runner cross section dimensions are cavity layout, material of molded part and volume of molded part. Cavity layout designed upon determines length of runner channels and with known weight are determined cross section dimensions. (1) Fig. 1 shows cavity layout where:? L – sprue length? L1 – half length of main runner? L2 – half length of secondary runner? L3 – gate length.Fig. 1 Cavity layoutOverall length of runner system to single cavity is:LC= L1+L2+L3 = 55 + 33, 5 + 15, 5 = 94 mmMolded part volume: V = 61000 mm3Runner system volume: VCA = 4298, 96 mm3Material density (Cycoloy C2100HF): δ = 1,075 Molded part volume: G = = 61. 1,075 = 65, 57 gWall thickness of molded part: s = 2mmWith this parameters and nomograms are determined dimensions of trapezoidal cross section of runner channel.Value D180。圖31. 填充時(shí)間分析圖32. 冷卻時(shí)間的分析在想要的流道分析輸出后，基于有限元網(wǎng)格劃分的3D CAD 模型被準(zhǔn)備好（圖41）。在圖31，32中，是填充始時(shí)間與冷卻時(shí)間的輸出。主要的分析是47, 92%的分流道系統(tǒng)體積的減少輸出。圖23. 仿真模型分流道系統(tǒng)的優(yōu)化由MPI/Flow模型來(lái)展示。.
