洗衣机水管接口注射模具设计
摘要：在现代工业中，模具工业已成为制造业的基础，这一观点随着全球制造业向我国转移的过程中以被越来越多的有识之士所意识到。而在模具行业中塑料模又是其重中之重，种模具占模具行业总份额的50％以上，我国的塑料成型模具设计，制作技术比较晚，整体水平还比较低。目前单型腔、简单型腔的模具达70%以上，仍占主导地位。本论文介绍了洗衣机水管接头的注射模设计过程。从型腔数量和布局的确定、注射机选择、浇注系统设计、模板及其标准件的选用、脱模及抽芯机构的设计、成型部件的设计等一一进行了详细的介绍。塑件有侧孔，需要设计侧向抽芯机构，增加了模具的复杂程度。

Design of Injection Mol forUnion of Washing machine
Mechanical Design & Manufacturing and
Automation
Abstract：In the modern industry, the die industry has become
the
foundation of the manufacturing industry, this standpoint was along
with the process that worldmanufacturing industry transfer to our
country, which was been aware of by the private who more and more
know. But in die profession plastics mold was heavy its heavy
inside again,this kind of molding tool accounts for 50% of total
quota in profession in molding tool above. In our country,because
of the late of manufacture beginning the totalitily standard of
mold design was very low about the plastics of taking shape.
Nowaday,The proportion of odd casement, simple casement mold was
over 70percent which was still dominant. This paper introduces the
main process of the injection mould designing of the union,recounts
the detail asthesefollowed:deciding of the number and the
arrangement of the cavity, the detrusion components ,core-pulling
outfit,and the feed system; selection of the machine for
injection,the moulding boards and the
standardized parts .The plastics has one side hole,so needs to
design a core-pulling part from the side. As a result ,it adds the
complexity of the mould.
Keywords : injection mould;core-pulling;union.
