摘要QC接线端子的材料为 PC,对其结构工艺性和注塑工艺性进行分析。并对以往的设计进行改进,避免了侧抽芯,简化模具结构,降低了模具制造成本。在整个设计过程,利用UG对模型进行三维建模,利用Mold WiZard模块分型,对型芯与型腔的结构进行设计。设计了专用推杆,完成推出机构的设计。同时也对其他各个系统进行设计。并利用MOLDFLOW进行了模流分析,利用CAE分析寻找最佳浇口位置,对填充过程进行模拟仿真,对熔接痕、 气穴等缺陷进行预测,并提出解决的方法。不断优化方案,提高模具的制造质量,最后利Mold WiZard 模块进行模架添加。完成了模具设计。UG与MOLDFLOW的结合使用,大大的提高了模具设计的速度与质量,同时也降低了成本。73904

The design of QC terminas injection mold
Abstract Firstly, introduced the development of Mold industry in domestic and foreign。 We take QC terminal materials, structure machinability and injection molding technology into consideration to modify Mold, which avoided the side core pulling, simplified the mold structure and reduced Mold manufacture costs。 In design process, 3D modeling build by UG, Mold WiZard module used for part, designed the structure of core and cavity。 Designed a special push rod, complete the design launch mechanism as well as design for other systems。 Then, we not only use MOLDFLOW to mold flow analysis, and CAE analysis was used to find the best gate location, simulation of filling process to predict defects such as the weld and the air traps, but also put forward for the solution。 Optimize the program, improve the quality of mold manufacturing, mold base was finally added by mold wizard module to complete the mold design。 The combination of UG and MOLDFLOW greatly improving the speed and quality of the mold design, but also reduce the costs。
