电话机上壳注塑模设计
摘要
根据塑料电话机上壳的要求，了解塑件的用途，分析塑件的工艺性、尺寸精度等技术要求，选择塑件制件尺寸。本模具采用一模二件，侧浇口进料，注射机采用海天200XB型号，设置冷却系统，CAD和UG绘制二维总装图和零件图，选择模具合理的加工方法。附上说明书，系统地运用简要的文字，简明的示意图和和计算等分析塑件，从而作出合理的注塑模具设计。
按国家职业定义，模具设计是：从事企业模具的数字化设计，包括型腔模与冷冲模，在传统模具设计的基础上，充分应用数字化设计工具，提高模具设计质量，缩短模具设计周期的人员。
模具，是以特定的结构形式通过一定方式使材料成型的一种工业产品，同时也是能成批生产出具有一定形状和尺寸要求的工业产品零部件的一种生产工具。大到飞机、汽车，小到茶杯、钉子，几乎所有的工业产品都必须依靠模具成型。用模具生产制件所具备的高精度、高一致性、高生产率是任何其它加工方法所不能比拟的。模具在很大程度上决定着产品的质量、效益和新产品开发能力。所以模具又有“工业之母”的荣誉称号。
模具设计与制造专业的培养目标是：培养德、智、体、美等方面全面发展，具有良好的职业素质，面向制造行业，从事模具设计、模具加工工艺编制、冲压和塑料成型加工、数控机床的操作以及生产管理等工作的高等技术应用性专门人才。体现为制造方面达到模具制造的补师水平，设计方面达到助理设计师的水平

Abstract
According to the requirements of the shell of the plastic telephone, the use of the plastic parts is understood, the technological requirements of the plastic parts, the dimensional precision and so on are analyzed, and the size of the parts of the plastic parts is selected. This mold adopts the first mock exam two, side gate, injection machine adopts the Haitian 200XB model, set cooling system, CAD and UG drawing two-dimensional assembly and parts drawing, choose the reasonable processing method of mould. The instructions are attached, and the simple text, simple schematic and calculation are used to analyze the plastic parts so as to make a reasonable design of the injection mold.
According to the definition of the national occupation, the mold design is to engage in the digitalized design of the die, including the cavity mold and the cold die, and apply the digitalized design tools to improve the quality of mold design and shorten the design period on the basis of the traditional mold design.
Mold is a kind of industrial product that moulds materials in certainways in a specific structure form. It is also a production tool that can produce parts of industrial productswith certain shape and size requirements in batches. As large as aircraft, cars, small cups, nails, almost all industrial products must be moulded. The high precision, high consistency and high productivity produced by the mold production are incomparable to any other processing methods. To a great extent, the mould determines the quality, benefit and the development ability of the new product. So the mold also has the honorary title of"the mother of industry".
Training target of mold design and manufacturing specialty is to cultivate all-round development of morality, intelligence, body, beauty, good occupation quality, manufacturing industry, advanced technology and specialized personnel engaged in mold design, process design, mold stamping and plastic molding processing, CNC machine tool operation and production managementwork. To achieve the level of mould making in manufacturing, and to achieve the level of assistant designer in design.
Keywords: telephone shell; the first mock exam two; side gate feeding; injection machine, injection mold cooling system;
