1.0MM 1.5MM 6.0MM 第二色单咀尖点式进胶，增加一段胶位辅助进胶，尺寸如下图所示。 Second shot:HRS drop(tip) into part ,and add a length of plastic to contribute melt filling as indicated in the picture. Suggest to create a runner on top of the 1st shot for gating. Gate size 1.5mm 45 deg. 6mm 1.5mm 60 deg. 热流道转4点潜进胶，具体位置待模流分析确定 4 drops HRS, sub-gate, Gate location will finalize after mold flow study. 4 hot drops to cold runner sub-gate. Gate location to be finalized by Moldflow study. 0.8mm 1.5mm Φ5mm Φ6mm Φ5mm 热咀 注：走胶平衡要等模流分析后再调整。 Melt filing balance will finalize after mold flow study. Shoot balance to be adjusted/optimized as per moldflow study. 产品1：这个产品还有一件镜像体，这里不重复分析。 70.67 2.64 Part 1: RH and LH is mirrored so only one of it is shown in this report. 注意，本文件底色绿色部分的翻译文本为比较合适的表述效果。 镶针深入0.10MM封胶，避免出披锋。 To avoid occur flash ,suggest to let insert go deep into seal off surface 0.01mm Suggest to create a 0.1mm concave at core (cavity) steel for the pin insert seal off in order to optimize/improve the flash direction, if any. Improve: 改善 Optimize：优化 Tuning：调整 ,if any: 如果有的话 In case 0.1MM 前后模镶针碰穿，避免出现段差，前模镶针比后模镶针做大0.1MM. Due to core insert pin shutting off,suggest to make the size of cavity insert pin biger 0.1mm than core insert pin size to avoid occur lever mark There is shutoff between core pins, we suggest to make cavity side core pin 0.1mm bigger. 如图，红色部分出前模，产品减胶0.05MM Indicated red surface for cavity,suggest to remove material 0.05mm 分型面与骨位底面平行 PL surface be parallel to the bottom surface of rib The surfaces in red is formed by the cavity which need to create positive draft by removing material, max. 0.05mm Positive：正面的 Negative: 负面的 Draft: 出模角 MMC: Maximum Material Condition Parting line will be in parallel to the bottom surface this rib. 所指红色面直身，建议往前模加胶拨模2度，最大加胶0.06MM 详见修改后的产品3D 所指红色面倒扣，建议往前模拨模0.3 度，最大加胶0.19MM 详见修改后的产品3D 所指红色面倒扣，建议往前模加胶拨模2度，最大减胶0.13MM 详见修改后的产品3D Indicated red surface without draft angle,suggest to apply 2 degree at the cavity side,max. material added is 0.06mm,more details r
