169、;70前 言本设计分为两部分，一部分是对滴注仪的上盖和下盖进行结构设计，一部分是对滴注仪的下盖进行模具设计。所以本设计分两个阶段完成，第一阶段结构设计大概要一个月的时间；第二阶段模具设计大概要两个月的时间。首先，根据给定的主pcb板的大小、按键个数、拨码盘的个数、计算机串口插座、电源插座及扬声器，进行滴注仪的结构分析，其中包括尺寸的计算及测量，根据各部件的形状确定部件的摆位，以次进行结构设计。设计出来的形状力求使用，结构简单，外形美观。同时设计的时候还要考虑加工制造的可能性。因为滴注仪是用注塑模注塑成型的，所以在设计时应考虑设计的形状能注塑的可能性。其次，根据设计出来的下盖形状，对下盖进行模具

170、设计，在进行模具设计时，根据塑件的形状并结合手册循序渐进的进行模具设计。这次模具设计是对以前所学知识的一次实践。由于我没有实践经验所以很多东西都要依靠手册。包括数据的选取和工艺性的确定。模具设计包括浇注系统、冷却系统及动、定个部分的结构的设计。在设计时要使用到autocad2000和pro/engineer，这些计算机辅助设计软件对于提高设计的速度和质量很有帮助，这也是当今模具行业发展的选择。在近四个月的设计中，为了更好地完成任务，期间还到工厂进行了实习，参观了塑料模具的生产加工过过程，这加强了我们的感性认识，更有利于我们完成模具设计。感谢老师对我们的关怀和指导，感谢同学们的帮助。我这次设计的
