1、本科毕业设计（论文）通过答辩激光标线仪前盖模具设计及其型腔仿真加工摘要：本课题是关于激光标线仪前盖模具设计及其型腔仿真加工。设计之前要对塑件制品进行测绘，得到塑件制品的尺寸数据。在设计该模具时，首先解决了抽芯的问题，考虑到夹角为20°的侧向抽芯机构所面临的导向、定位、锁紧问题。本模具依据厂方给定的注塑机型号和经济性确定型腔为一模两腔；为了不影响制品的外观，本设计采用潜伏式浇口；为使塑件能够快速均匀冷却，冷却流道布置为环绕式；其次，进行模具的各个零部件的具体设计。对成型部件和紧固件及各种支撑件进行外形尺寸设计和强度校核。为了降低模具的生产周期，提高生产效率，选择315315的标准模架。

2、本设计对激光标线仪前盖型腔的加工工艺进行了分析，在MasterCAM9.0中完成刀具路径设定，确定数控加工代码，通过仿真加工确定是否满足加工要求。通过工艺性分析，检验了设计的可行性和经济性。关键词：测绘；抽芯机构；注塑模具；加工仿真机械模具毕业设计（论文），优质质量，通过答辩，毕业无忧盐城工学院本科生毕业设计说明书2007MouldDesignuppercoverandProcessingSimulationofCavityoftheLaserGraticuleMeterAbstract:Thistopicistodesignthemouldoftheuppercoveroflaser
