With the cold stamping process applications, and many auto parts form and accuracy improved. Side damping film processing method has also made progress, and finally formed by cold stamping process. Recent years, cold stamping process has been widely development.cold pressing is built on the metal plastic deformation, based on the use of the installation at room temperature in the mold press to exert pressure on the material to produce separation or plastic deformation, and thus obtain a certain shape, size and performance parts a processing methods. In the cold will materials (metal or non-metallic) processing into parts (or semi-finished products) is a special technique and equipment, known as the cold stamping die (commonly known as Die). Die in the achievement of cold stamping processing technique and equipment is essential, there is no mold advanced technology, advanced stamping process can not be achieved. With the rapid development of the national economy, stamping technology development and new types of mold material constant research and development, the market's growing demand for mold, mold also occurred in the structure of certain changes in mold manufacturing and assembly have been greatly affected. In recent years, the mold industry has been around 15 percent to the growth rate of rapid development. Mold is a technologically advanced machinery manufacturing industry, an important and far-reaching process equipment, with the production of high efficiency, high utilization of materials, parts quality, technological adaptability and good characteristics, are widely used in automobiles, machinery, aerospace, aviation, light industry, electronics, electrical appliances, instrumentation and other industries. First, after decades of development, stamping die industry was the rapid development, embodied in: (1)-aided design / processing / engineering and technology are widely used. (2) large-scale enterprises have a high-speed mold CNC machining / Machining Center / CNC machine tools and other advanced processing technology and equipment, they can conduct RP / RT or Die reverse engineering work, hardware and equipment have been standing with the world level of the basic synchronous online . (3) in the die surface finishing processing technology, to carry out an active exploration and accumulated some experience. (4) automotive panel, represented by large, complex, precision stamping die, using CAD / CAM / CAE software for three-dimensional design and simulation to reduce the test time and shorten the cycle mode. With high-speed, precision processing equipment production, access to good dimensional accuracy and surface roughness, using a new type of grinding or polishing method to replace the traditional manual abrasive polishing, to improve the quality of mold. These represent the development trend of stamping dies. Second, the international mold manufacturing technical characteristics are as follows: (1) product specialization body mold enterprises to professional development, such as Germany Volkswagen mold factory, mold factory Audi AG, SCHULLER companies, companies COMAU Italy, the United States AUTODIE, SECKLY, Japan's Toyota Mold Factory, Ogihara, Fujitsu Corporation, Hyundai Motor Dies center. Some professional mold manufacturing overall Wai side, some specializing in the production of four molds, and some specialize in the production floor and the structure of mold. Die to the Multi-Position Progressive Die automation and direction. (2) to create digital three-dimensional physical design widely used in mold manufacturing, the two-dimensional to three-dimensional map DL after DL chart can be used directly in finite element analysis and numerical control programming, the use of CAE analysis of 100 percent. Mold Design using 3D parametric design. Achieved a range of plate forming mold design, mold to the same mode of production. Die CNC machining technology, including EPC technology, the refinement of programming, high-speed processing technology, face NC technology to strengthen and repair. Third, stamping die manufacturing technology development trends: (1) manufacturing stampings with traditional metal materials, are gradually being high-strength steel plate, coated steel plating, plastic laminated steel and other composite materials or polymer materials substitution. With the development of materials science, strengthen the research of new materials stamping performance, continuous development and improvement of metal forming technology. (2) fine blanking and semi-fine blanking, hydroforming, spinning forming, explosive forming, electric water forming, electromagnetic forming, superplastic forming, such as technology development and applications, some of the traditional processing methods will be stamping their replaced by punching processing products become more reasonable and more economical. Fine Blanking technology which has been relatively rapid development, Fine Blanking is an advanced manufacturing technology, can be used to replace certain parts machining with high-quality, high efficiency, low consumption, application characteristics of Canton. Gear plate in terms of fine blanking, in ordinary hydraulic fine blanking machine, technique and equipment is simple and precision workpiece. Its sheet metal as raw material, the use of less without cutting the plastic processing methods, one can get the size shape and high precision, low-shear surface roughness of the parts, the use of fine blanking technology known as fine blanking parts, pieces. (3) With the development of computer graphics technology matures, the field of metal forming in recent years the rise of the computer-aided design (CAD), computer aided engineering (CAE) and computer-aided manufacturing (CAM) technology. The technology of traditional stamping technology changes have had an important impact. Especially the numerical simulation of sheet metal forming technology, so that sheet metal forming technology to rid itself of the "experience" and "qualitative" level, has entered a "scientific" and "quantitative" stage of development. The use of this technology for sheet metal forming process simulation, you can predict metal stamping process flow, stress and strain and thickness distribution, die by the strength and wrinkle, break down, the impact of lines of possible defects and failure mode. This is to optimize process parameters and die structure provides a very effective tool in reducing or even abolishing the test mode process, shorten the product development cycle and reduce the cost of product development plays an increasingly important role, has become the guiding mold design and optimization an important tool. (4) high-speed milling process, both at home and abroad in recent years the development of high-speed milling process to improve the processing efficiency, and access to high surface finish. In addition, high hardness module can also be processed, also has a low temperature rise, thermal deformation of the small advantages. High-speed milling technology, automobile, home appliance industry, a large cavity mold manufacturing has injected new vitality. At present it has more agile, intelligent, integrated direction. (5) die scanning and digitizing system, high-speed scanners and mold scanning system provides a model or in kind from the scan to be processed into the desired model number of the necessary functions, greatly reducing the mold in the development of the manufacturing cycle. Some quick scan system, which can quickly installed in existing CNC milling machine and machining center, the fast data acquisition, automatic generation of a variety of CNC machining process, the CAD data in different formats for the mold manufacturing industry " Reverse Engineering. " Die scanning system has been in the automotive, motorcycle, household appliances and other industries has been successfully applied, I believe in the "Tenth Five-Year" period will play a greater role. (6) high-quality materials and advanced surface treatment technologies, high-quality steel and application of the corresponding surface treatment technology to improve the life of mold it is very necessary. Mold heat treatment and surface treatment can give full play to the die steel material properties of the key link. Mold heat treatment is the development direction of vacuum heat treatment. In addition to improving the mold surface treatment technology should be developed advanced vapor deposition, plasma spraying techniques. Fourth, stamping machinery manufacturers in the position and characteristics: Pressing both capable of producing small-size instrument parts, but also capable of producing beams, such as automotive, pressure vessel head for a class of large parts; both capable of producing the general size and shape of the tolerance level of spare parts, also capable of producing precision (tolerances in the micron level ) and the complex shapes of parts. The world's steel production accounted for 60% ~ 70% of the plates, tubes and other profiles, most of which are made after stamping products. Stamping in the automotive, machinery, household appliances, electrical, instrumentation, aerospace, weapons manufacturing, a very important position. Stamping parts of the light weight, thickness, stiffness good. Its size tolerance is guaranteed by the mold, so the quality of stability, in general no longer be used by mechanical cutting. Cold metal stampings and mechanical properties superior to the original blank, smooth surface appearance. Cold stamping tolerance level and surface state is superior to hot-stamping parts [6]. Stamping production technology and equipment is growing, with the exception of the use of the traditional mold presses and steel stampings, the hydroforming and spinning forming, superplastic forming, explosive forming, electric water forming, electromagnetic forming a variety of special Stamping technology is also developing rapidly, the press raise the level of skills to a new height. Special metal forming process is particularly suitable for many species of small and medium-sized quantities (or even dozens of) parts production. For ordinary stamping process, to be used in simple mold, low melting point alloy die, die and stamping group flexible manufacturing systems, organizations and more species of small and medium-sized quantities of stamping parts processing. In short, stamping die with high productivity, low processing costs, material utilization high, simple operation, easy to achieve mechanization and automation are a number of advantages. The use of stamping and welding, bonding and other composite process, so that more reasonable structural parts, processing more convenient, you can use relatively simple technology to create more complex structure.南京理工大學泰州科技學院本科生畢業(yè)設計（論文）選題、審題表姓 名 丁武學系　　部 機械工程系指導教師專業(yè)技術職 務 副教授課題名稱 車燈注射模設計適用專業(yè) 機械工程及自動化A B C D E A B C D課題性質? 課題來源 ?大 適中 小 難 適中 易課題預計工作量大小 ?課題預計難易程度 ?課題簡介塑料件在各行各業(yè)及日常生活中使用越來越多，塑料模具的設計制造的社會需求日益增長，要求也越來越高，同時社會對具有三維CAD 設計能力的人才需求也日益增長。車燈塑件形狀較復雜，模具含側抽芯結構，通過車燈注射模設計，對學生進行模具設計、工藝設計的基本技能訓練與培養(yǎng)，使學生基本掌握利用三維 CAD 軟件進行工程設計的方法，培養(yǎng)學生應用所學知識進行工程設計的能力，適應社會需求。課題應完成的任務和對學生的要求1．測繪塑件圖紙。要求實測實物尺寸，合理確定零件精度，利用三維 CAD 軟件進行實體造型，生成工程圖紙；2．完成塑件注射模方案設計和設計計算；3．全部模具零件圖、裝配圖紙設計。要求所有成型零件完成三維實體造型后生成工程圖；4．模具制造工藝設計。要求完成主要零件工藝設計；5．編寫設計說明書。所在專業(yè)審定意見：專業(yè)負責人(簽名)： 年 月 日本課題由 張 彪 同學選定，學號： 05010256 注：1．該表由指導教師填寫，經(jīng)所在專業(yè)負責人簽名后生效，作為該專業(yè)學生畢業(yè)設計（論文）選題使用；2．有關內容的填寫見背面的填表說明，并在表中相應欄內打“√” ；3．課題一旦被學生選定，此表須放在學生“畢業(yè)設計（論文）資料袋”中存檔。
