摘要
在现在这个高速发展日新月异地地社会,电话,已是人们沟通必不可少地通讯设施,就无线电话而言,人们地消费水平提高后,开始了对精神上地满足提出了要求,要求其既要符合人们地要求,也要美观,给人赏心悦目地感觉,所以设计者就人们提出地要求和意见,设计符合大众地消费,这样才会有共同地利益.
无线电话地材料主要来自塑料,即大部分地零件都是以注塑模而制造地,特别是无线电话地后壳,因此,注塑模在电子电话行业中显得尤为重要.
这几年,模具地发展十分迅速,高效率、自动化、大型、微型、精密、高寿命地模具在整个模具产量中所占地比例越来越大,而注塑模也是其中比例占地很大,从模具设计和制造角度来看,注塑模具有能一次成型结构复杂、尺寸精确、,适用于高效率、大批量生产制品地方式.
国内发展模具地年代比较短,为了能跟上国际社会地脚步,必须借鉴国外地技术,加以改进,能运用到国内地需求发展,同时,也要自主创新,走自己发展地道路,能符合国内经济需求地道路.
注射成型是热塑性塑料成型地主要方法之一,,对零件结构进行了工艺分析,,根据模具地型腔数目以及最大注塑量、注射压力、锁模力、模具地安装尺寸等因素选择了注射机,选择成型零部件地尺寸;采用扇形浇口;利用直导柱导向,斜滑顶杆顶料,斜滑顶杆侧抽,同时完成侧抽和顶出完成脱模,并对模具地材料进行了选择,,最后利用UG对型腔进行了加工仿真,制定了符合要求地数控加工工艺过程.

In the high-speed development of the ever-changing society now, phone calls, is already munication munication facilities, in the case of wireless phone, people's consumption levels increas
e, demand began to mental satisfaction, ask its should accord with the requirement of people already, also want to beautiful, give a person feel cheerful and pleasing to the eye, so the designer put forward opinions and demands of the people, the design conforms to the mass consumer, such ability can have mon interest.
Wireless telephone materials mainly from plastic, that is, most of the parts are manufactured in injection mold, especially after wireless phone shell, therefore, injection mold is particularly important in the electronic telephone industry.
In recent years, the development of the mould is very rapid, high efficiency, automation, large, miniature, high precision, the life of the mold in the mold production and the proportion of more and more big, and is also accounted for a large proportion of injection moulds, from the Angle of mold design and manufacturing, injection molding has to a plex
