【摘要】塑料的主要成分是高分子聚合物，并且成本原料广泛，成本原料低，如果用它制作人们所需要的产品，可以达到理想的废品使用率。在塑料变为成品时主要用到了注塑模具。因此大力研究注塑模具可有助于我们对塑料产品生产过程的了解，并且还可以大大提高产品的质量。塑料不被加工成制品，就相当于随处可见的垃圾。所以只有塑料成品才具有一定的价值。塑料制品的生产可使塑料原料成为具有一定形状而又有使用价值的物品或定型材料，但这要求我们对于各种塑料的性能，各种工艺方法等技术要求有一定的认识。为了考量塑件制件尺寸。首先，我们必须明确制件应达到的技术使用要求以及使用环境，比如对粗糙度的要求，对抗拉抗压性能的要求，对潮湿性能的要求。只有明白了制件的要求，我们才能选用合理的塑料进行加工，才能使用合理的注塑方法，达到合理的尺寸大小，适当的精度等级。才能更加深刻的明白塑料的性能。模具设计一般为一模一腔，一模两腔与一模四腔，综合考虑各种因素，本模具采用的一模两腔。查阅相关资料，了解注射机的各种性能指标后，我觉得海天HTF160X2B最适合本模具的设计。CAD、Pro/E可谓产品设计不可或缺的东西，我们用CAD进行零件图和总装图的精心绘制，利用Pro/E进行模具的三文成型。并且还可以利用Pro/E得到相应的数量关系。减少了繁重的工作量。39604

Telephone seat bottom screen three-dimensional modeling and mold design
[Abstract] The main component of plastic is a polymer, and the cost of raw materials widely used, low cost raw materials, if people use it to produce the desired product, can achieve the desired scrap usage. When the plastic into finished products mainly used in the injection mold. Therefore strongly of Injection Mold can contribute to our understanding of the plastic production process, and also can greatly improve the quality of the product. Plastic not be processed into products, the equivalent of garbage everywhere. Therefore, only plastic products only have a certain value. Plastic products, plastic raw materials can become objects of a certain shape or amorphous materials and have use value, but it requires us to the performance of various plastics, various process methods and other technical requirements for a certain degree of understanding. To consider plastic parts size. First, we must clear technical requirements to be met by parts and the use of the environment, such as the requirement for roughness against pull compression performance requirements, performance requirements for humidity. Only understand parts of the requirements, we can choose a reasonable plastics processing, injection molding to use reasonable methods to achieve a reasonable size, the appropriate level of accuracy. In order to more deeply understand the performance of plastics. Mold design is generally a model of a cavity, a two cavity mold and a four-cavity mold, considering a variety of factors, a mold cavity of the mold using two. Access to relevant information about the kinds of performance injection machine, I think the Haitian HTF160X2B most suitable for the mold design. CAD, Pro / E product design can be described as something indispensable, we use CAD were carefully drawn diagrams and assembly diagrams of parts, with Pro / E mold three-dimensional shape. And also with Pro / E to afford the corresponding number of relationships. Reduce the heavy workload.
