摘要
塑料模具的发展是随着塑料工业的发展而发展的。近年业,人们对各种设备和用品轻量化要求越来越高,这就为塑料制品提供了更为广阔的市场。
本设计对“洗衣机管接头”进行研究和讨论,分析了其工艺特点,介绍其注射模结构及模具的工作过程,系统阐述了注射模设计过程,对洗衣机管接头塑料制件结构和成型工艺进行分析,主要包括成型位置及分型面的选择,模具型腔数的确定及型腔的排列,流道布局和浇口位置的选择,模具工作零件的结构设计,推出机构的设计,拉料杆的形式选择,排气方式设计等,并对锁模力、注射压力、开模行程等进行校核,以及模具零件材料的选择和制造进行了分析。
本设计方案结构紧凑,满足制品大批量生产、高精度、外形复杂的要求,设计参考了以往注射模具的设计经验,并结合制件性能,简化设计机构,并且运用AutoCAD、Solidwork等软件进行二维和三维绘图,缩短了生产周期,获得良好的经济性能。
关键词:洗衣机管接头;塑料注射模;侧抽芯
Abstract
The plastic mold's development is develops along with the plastics industry development. In recent years, the people were getting higher and higher request to lightweight of each kind of equipment and the thing, this has provided a broader market for the plastic products.
The design of the "washing machine pipe" to carry out research and discussion, and analysis of the characteristics of its technology to introduce the structure of injection mold and die work processes, systems on the process of injection mold design, plastic fittings for washing machine parts structure and forming process analysis, including the location and the molding surface of choice, to determine the number of mold cavity and the cavity flow arrangement and the layout and the choice of gate location, the work of parts of the structure of mold design, the introduction of institutional design, drawing materials under the form of options, such as exhaust design.
pact design to meet the mass production of products, high-precision, complex shape designed with reference to past experience in injection mold design, combined with performance parts to simplify the design and use of AutoCAD, solidwork software, such as two-dimensional and three-dimensional graphics and shortened the production cycle, access to good economic performance.
Key words:washing machine pipe l; injection mould design; core-drawing
