摘　　要：一种滑移门下导轨限位机构是左、右对称件,呈"U"形状,结构较复杂,外形尺寸较大,给模具设计增加了一定的难度。对此,在设计中运用功能较强的三维CAD/CAM软件UGNX进行产品的数值建模,为模具制造模型的创建提供了依据。文章通过对产品进行工艺分析,确定弹片外侧安装的合理性和一种滑移门下导轨限位机构采用的焊接连接方式,由此降低采购成本和制造成本,设计出高性价比的产品。Concerning the spacing mechanism of the lower guide rail in the sliding door,the left and right symmetry properties, the＂U＂shape,the complex structure,the large dimensions,all of these increase certain difficulties to the design of the mold.In this regard,the application of the more powerful 3D CAD/CAM software UGNX in the numerical modeling of the product provides a basis for the creation of the model for the mold fabrication.This article determines the reasonableness of the outboard mounting of the shrapnel and a welding connecting method adopted in the spacing mechanism of the lower guide rail in the sliding door by analyzing the process of the products.Thus,it reduces procurement costs and manufacturing costs,designs products of high price performance ratio.
