摘     要
    模具技术是上世纪下半叶制造业中发展最快的技术之一，模具的设计和制造是一个非常复杂的过程，并且是一个不断反复的过程。做为踏入社会的当代学生，就应该掌握扎实的专业基础，现在学好理论基础，希望通过这次设计，能掌握模具设计的基本方法和基本理论。本次设计就是利用冲压模具来制造喇叭罩成型模，冲压是利用安装在冲压设备（主要是压力机）上的模具对材料施加压力，使其产生分离或塑性变形，从而获得所需零件（俗称冲压或冲压件）的一种压力加工方法。冲压通常是在常温下对材料进行冷变形加工，且主要采用板料来加工成所需零件，所以也叫冷冲压或板料冲压。冲压是材料压力加工或塑性加工的主要方法之一，隶属于材料成型工程术。模具是制造业的一种基本工艺装备，它的作用是控制和限制材料（固态或液态）的流动，使之形成所需要的形体。用模具制造零件以其效率高，产品质量好，材料消耗低，生产成本低而广泛应用于制造业中。模具工业是国民经济的基础工业，是国际上公认的关键工业。模具生产技术水平的高低是衡量一个国家产品制造水平高低的重要标志，它在很大程度上决定着产品的质量，效益和新产品的开发能力。振兴和发展我国的模具工业，正日益受到人们的关注。

Mould for the speaker enclosure design
Abstract
Die technology is in the second half of the manufacturing sector in one of the fastest growing technology,Die design and manufacturing is a very complicated process and is a constantly repeated the process.As the contemporary students into the community, they should have a solid professional foundation, now based learning theory, the hope that through the design, mold design can grasp the basic methods and basic theory.The design is to make use of stamping die speaker enclosures-forming, stamping is installed in the use of stamping equipment (mainly press) on the mold to exert pressure on the materials to produce plastic deformation or separation, to obtain the necessary components (commonly known as Stamping or punching.) a pressure processing methods.Stamping is usually at room temperature deformation of the material cold processing, and mainly used to process sheet metal parts as required, also called cold stamping or sheet metal. Stamping is the pressure processing or plastic materials processing one of the main methods, materials forming part of engineering. Die is one of the basic manufacturing technology and equipment, it is the role of control and limitation of materials (solid or liquid) flows, so that the required physical form. Mould manufacture parts for its high efficiency, good quality products, low consumption of materials, production costs low and widely used in the manufacturing sector.Die industry is the foundation of the national economy industries, is internationally recognized the key industries. Die production technology level is the level of a country's manufacturers an important indicator of the level of its products to a large extent determine the quality, efficiency, and new product development capability. Revitalization and development of China's mould industry, are increasingly subject of concern.
