摘要;
摸具设计与制造是现代的一种综合性的、实用性的、应用性的、实践性强的制造技术新学科。在现代工业追求高效率以及大批量的制造产业中，摸具是作为最重要的工业制造工具之一，摸具是通过注塑、吹塑、挤出、压铸等一系列的成型手段得到所需的大批量产品的工具。被称为“工业之母”。在铸造、锻造、冲压、塑料、玻璃、粉末炼金、陶瓷制品等成型制造行业得到极大的发展。又由于摸具有提高生产效率，节省材料以及降低成本，保证尺寸的精度等的优点，所以它在关于民用、军事的各个行业都有广泛的应用。
伴随着在中国现代制造行业的技术发展，工业产品的数量和质量的要求也随之提高，产品的更新换代速度加快，对于其外观质量也随之增长。摸具设计也承担着为相关行业以及成形制造部门提供产品的重任。因为这些原因，近几年摸具技术也在不断的进步。对成型零件进行摸具的设计不仅仅是模具制造的第一步，也是正确以及快速制造摸具的基础，也是一项知识运用综合性高、成形制造实用性强的先进制造技术。在各种现代生产技术中占有很高的地位。摸具是制造精密成型零件的一种工具。模具包括塑料模具和冷冲模具，由各种零件构成，不同的摸具也由不同的构建组合而成。
模具在现代工业大批量成型制造行业中是作为最为重要的工艺装备之一，它不但广泛应用在铸造、锻造、冲压等成型制造行业中。也在塑料、粉末冶金、陶瓷制品这些日用行业中有发展。采用摸具进行制造生产不但有提高生产效率、节约原材料的优点，还有降低成本以及可保证较好的加工质量要求的优点。因此，很多产品的基础部件都采用模具进行加工生产。
随着科学技术的不断发展，工业产品不断增加的品种以及数量，快速更新换代的产品以及对产品表面质量和外观都提出了更高的要求。模具设计的部门肩负着为相关企业提供模具的重任。如果我们的模具设计及制造水平落后的话，产品质量就会变得低劣。制造周期和其它相比变长，必将会影响到产品的更新换代，不但会失去与同行业的竞争能力，也会阻碍发展生产和经济。所以，模具设计与制造技术在百姓日常生活中有着十分重要的作用。
本次设计绘图采用CAD,NX等设计绘图软件。CAD是一款绘制平面的机械制图软件，有良好的图像处理功能。而NX是一款绘制三维立体的机械制图软件，

Abstract;
Tool design and manufacturing is a new subject of modern manufacturing technology which is comprehensive, practical, applied and practical. In the modern industry pursuing high efficiency and mass manufacturing industry, moulding tool is one of the most important industrial manufacturing tools. Moulding tool is a series of moulding means such as injection moulding, blow moulding, extrusion, die casting and so on to obtain the required mass product tools. It is called "the mother of industry". In foundry, forging, stamping, plastics, glass, powder metallurgy, ceramic products and other forming manufacturing industries have been greatly developed. Because it has the advantages of improving production efficiency, saving materials, reducing costs and ensuring the accuracy of size, it has been widely used in various industries of civil and military.
With the technological development of modern manufacturing industry in China, the requirement of quantity and quality of industrial products has also been improved, the speed of product renewal has been accelerated, and the appearance quality of industrial products has also increased. Die design also undertakes the responsibility of providing products for related industries and forming manufacturing departments. Because of these reasons, in recent years, touch technology is also constantly improving. Mould design for forming parts is not only the first step of die manufacturing, but also the basis of correct and rapid tooling manufacturing. It is also an advanced manufacturing technology with high comprehensiveness and practicability. It occupies a high position in all kinds of modern production technology. Mould is a tool for manufacturing precision forming parts. Moulds include plastic moulds and cold stamping moulds, which are composed of various parts, and different moulds are also composed of different constructions.
Mould is one of the most important process equipment in modern industrial mass forming manufacturing industry. It is not only widely used in foundry, forging, stamping and other forming manufacturing industries. It has also developed in the daily use industries of plastics, powder metallurgy and ceramics. Mould manufacturing not only has the advantages of improving production efficiency and saving raw materials, but also has the advantages of reducing costs and guaranteeing better processing quality requirements. Therefore, many basic parts of products are processed and produced by dies.
With the continuous development of science and technology, the increasing variety and quantity of industrial products, the rapid updating of products and the higher requirements for product surface quality and appearance are put forward. Mould design department shoulders the responsibility of providing moulds for related enterprises. If our die design and manufacturing level is backward, the product quality will become inferior. Compared with other industries, the longer manufacturing cycle will inevitably affect product updating. It will not only lose the competitiveness of the same industry, but also hinder the development of production and economy. Therefore, die design and manufacturing technology plays a very important role in people's daily life.
This design drawing uses CAD, NX and other design drawing software. CAD is a mechanical drawing software for drawing plane, which has good image processing function. NX is a mechanical drawing software for three-dimensional drawing.
Key words: die design, cold stamping die design and manufacturing, layout.
