We know that the mold guide column products will have dents. These dents are called oil grooves. Some customers ask, what is the role of the oil groove of the mold guide column?
The mold guide post is to be moved relative to the guide sleeve during operation because the gap is small and the lubricating oil is scraped off for a long time. Therefore, the oil sump is designed so that the lubricating oil can stay on the mold guide post for a longer period of time without being completely scraped to one end.
In addition, because the machining accuracy of the oil groove on the guide post is different. Taking the secondary guiding precision as an example, the matching requirement of the sliding guiding part of the guiding post and the guiding sleeve is H7/h6, the matching part of the fixed part of the guiding post and the mounting hole of the mold base is H7/s6, and the oil groove divides the guiding column into two sections. One segment is h6 and the other segment is s6.
Therefore, in order to better play the role of the guide column, the oil groove of the mold guide column must be there!https://www.xhychromerod.com/
