淋浴喷头注塑模模具设计(含CAD零件图装配图)(任务书,开题报告,外文翻译,论文说明书9700字,CAD图纸13张)
摘 要
随着人们生活水平的提高，除了夏季有些地方的人仍会去一些河流等户外的地方洗澡，大部分人选择在室内，自家或者澡堂进行洗浴。由于担心卫生问题，大部分人还是选择淋浴的方式。为了更好的给人们提供便利，各种淋浴头孕育而出。注射模做为一种比较常见的注塑方式，现在被大部分工厂所采用。通过分型面的设计，制造者基本可以确定整个模具的外形，从而确定场地的大小，一般注塑车间并不需要太大。
淋浴头的设计生产较为简单。首先对淋浴头进行分析，确定适合的材料，注塑方式等。然后进行模具的设计制造，模具的设计对淋浴头的后续生产至关重要。模具就是利用材料之间力学，热学等物理性能的差异，利用模具材料远高于模具材料的熔点，硬度等，将原材料通过挤压，固定成型从而达到生产的目的。
淋浴头现在已经成为人们生活必需品之一，对它的需求量也日益增加，为了满足市场的需求，对设计工艺，成型工艺，加工工艺提出了很大的要求，在确保可以大量生产的同时还要考虑到生产成本，只有拥有低廉的价格，优越的性能才能广泛被人们所接受。

Abstract
With people’s living standard increasingly development, most of them prefer taking showers indoors instead of outdoors. For worried about the health problem, only a few people will bath in outside river at summertime.
In order to serve people better, various kinds of shower come out for convenience. As a way of common injection molding, injection mould has now been adopted by mostly factories. Generally, injection molding workshop does not need to be too big. They use the design of making different parts accordingly to help makers determine the whole mould. It is in this way can the maker determine the size of the venue.
The design of the shower head production is relatively simple. First, we should analyze the shower head, determine suitable materials and injection mode. Then for mould’s manufacturing, mold design is very important for the subsequent production of the shower head. Mould is using the material mechanics, the thermal differences in physical properties, such as using the principle that die mold material’s melting point is much higher than material, hardness etc., and to achieve the production requirements though extrusion and molding.
Shower head has now become one of the necessaries in our lives, and it’s demand is also increasing. In order to supply the market, the designers pay more attention on processing of designing, molding and remolding. They put forward a lot of requirements to ensuring that it can be both lower cost and high performance which will make them easily accepted by people.
