1.导柱、导套孔的加工导柱、导套分别安装于动模板与定模板,为模具合模用的导向装置,因此,动、定模板的导柱、导套孔的加工很重要,其相对位置误差应在0.01毫米以内。除了由座标镗床可以分别在动、定模上镗孔以外,比较普遍采用的方法是将动、定模板合在一起(用工艺定位销钉定位),在车床、铣床或镗床上进行镗孔。对于淬硬的模板,导柱、导套孔如在热处理前加工正确,则会在热处理后因孔形与位置变化而不能满足导向要求。因此在热处理前模板孔加工时应留有磨削余量,热处理后或用座
1. Guide post, guide hole processing guide post, guide sleeve were installed in the movable template and fixed template, the mold clamping with the guide, therefore, the fixed template guide column, guide hole processing is very important , The relative position error should be less than 0.01 mm. In addition to the boring by the standard boring machine in the dynamic and fixed mold respectively, the more common method is to combine the moving and the fixed template (locate with the craft positioning pin) and bore the lathe, milling machine or boring machine. For hardened template, guide post, guide hole, such as heat treatment before the correct processing, it will heat treatment due to changes in hole shape and position can not meet the guide requirements. Therefore, before the heat treatment template hole machining should leave grinding margin, after heat treatment or seat
