摘要谑且麋辛析岱怡箍甯辎孢茵冯
塑料注射模具是工业生产的基础工艺设备,在电子、汽车、电机、电器、仪表、家电和通讯等产品中,60%~80%的零部件,都要依靠模具成形。它不仅直接影响工业产品的水平,也是一个国家工业化程度和机械制造工业技术水平的综合体现。闯卯坤芍蒲逄麽醌婀份倘恭呖
照相机外壳是一类体积适中,形状、结构较为简单的塑料零件。根据照相机外壳的结构确定模具的结构方案,利用塑件的三维零件图,确定模具的主要结构方式,进而画出其模具的CAD装配图和零件图。赚扼筠晏佬棂旦纭麻委淮籀窘
通过对塑件的结构分析,本次设计采用一模四腔设计,滑块侧抽芯机构,实现照相机外壳侧孔的生成;采用侧浇口形式;塑件的体积适中,采用推杆推出实现脱料。采用此模具结构不仅可以保证塑件的表面要求和尺寸精度,而且生产率高、成本低、结构简单,可行性强,是一副实用性很强的模具。呖宸檗呕纱挟啜记腋烧秒馁妮

Plastic injection mould is the basis of process equipment in industrial production, in the electronic, automobile, motor, electrical appliance, instrument, home appliances munication products, 60%-80% of the parts, must rely on forming die. It not only directly affect the level of industrial products, is prehensive reflection of a country industrialization and machinery manufacturing industry technical
Camera housing is a kind of medium in size, shape, simple structure of plastic parts. According to the camera shell structure determine the structure scheme of the mould, plastic parts of the 3D part drawings, the main structure of dies, and then draw the production of plastic parts CAD parts and assembly
Through the structural analysis of plastic parts, the design adopts the design of a mold four cavity, slanted slide block core-pulling mechanism, realization of generating camera housing side hole; the side gate; moderate volume of plastic parts, the push rod is introduced to achieve stripping. The die structure can not only ensure the surface requirements of plastic parts and precision, and high productivity, low cost, simple structure, strong feasibility, is a very practical mould.
