长槽座的注塑模具设计-注射模含NX、proe三维及11张CAD图带模流+说明书

A三维塑件图

摘要
在科技发达的今天，注塑模具发挥了不小的作用，在机械、器械、用品的产品中都存在注塑模具的生产。从模具的开创至今模具设计和制造也是不断的进步与创新，以前绘制装配图都是用手绘制现如今科技发达绘制图纸只需要用电脑绘制，不仅仅绘制二维装配图连三维也能绘制。
本次设计的参考件是以长槽座为设计任务，此产品外形光滑简单，用UG三维软件绘制产品。在绘制过程中要考虑到抜模斜度，方便顶出脱模。绘制完成后，根据需求排列出一模二腔计算出他的模架，然后确定它的分型面。分型面的选择也要考虑到脱模的方向和零件的外形，还要考虑到型芯型腔的机械加工方便性和顶出机构的受力均匀。根据产品的排列和原料的流动性收缩率选择进料口使其填面不缺料。冷却方法根据模具的设计产品的摆放来确定，一般采用环绕式的水管。推出机构通常采用圆顶针，这种推模方式会留有顶出痕迹，如不能有顶出痕迹可使用推板推出或者使用机型手取出，选用的方式根据产品的使用和外观要求而定。三维软件绘制完成后根据图形再使用CAD绘制二维装配图和零件图，这样绘制二维装配图时思路清晰不容易出错。在设计过程中需考虑到模具在机械加工方面的制造工艺，还有就是在制造完成后模具使用的安全设备维修的方便跟换宜受损部分的简便，这都是在设计过程不可缺少的。

Abstract
In today's highlydeveloped science and technology,injection mold plays a great role in the production of injection mold in machinery,equipment and supplies.Die design and manufacturing has been a continuous progress and innovation since the beginning of the die.Previously,assemblydrawingswere drawn byhand.Today,advanced science and technologydrawings onlyneed to be drawn bycomputer,not onlytwo-dimensional assemblydrawings but also three-dimensional assemblydrawings.
The reference parts of this design are designedwith long groove base.The product has smooth and simple shape and is drawnwith UG three-dimensional software.During the drawing process,the slope of the die must be considered to facilitate ejection and demoulding.After the drawing is completed,one module and two cavities are arranged according to the requirements to calculate the frame and then determine its parting surface.The selection of parting surface also takes into account the direction of demoulding and the shape of the part,aswell as the convenience of machining the core cavityand the uniform force exerted bythe ejection mechanism.Choose the inlet according to the product arrangement and material flowshrinkage so that the filling surface is free of material.Cooling methods are determined bythe layout of the mold design product,generallyusing awater pipe enclosure.Push-out mechanism usuallyuses dome needle,whichwill leave a mark of ejection.If there is no mark of ejection,push-out plate can be used or model hand can be used to remove it.The selection depends on the use and appearance of the product.After three-dimensional software drawing is completed,two-dimensional assemblydrawing and part drawing are drawn according to the drawing and then using CAD.In thisway,it is not easyto make mistakeswhen drawing two-dimensional assemblydrawing.In the design process,it is necessaryto take into account the die manufacturing process in the field of mechanical processing,aswell as the convenience of repairing the safetyequipment used in the die after manufacture and the convenience of replacing the damaged parts,which are indispensable to the design process.
