What is a terminal mould guide post?

The guide post is a guide element used in combination with the parts in the mold to ensure that the mold can move and guide the mold stroke with accurate positioning. Bearing steel, hot working die steel, easy turning and iron cutting, etc. The material of guide pillar is generally selected, and bearing steel SUJ2 is widely used, which greatly enhances the durability and interchangeability of guide pillar. The guide pillar and the assembly form an outer guide pillar assembly and an inner guide pillar assembly, which have beautiful metallic luster. The roundness of the guide post is very demanding. The main purpose of drilling the center hole is to grind the outer diameter with a cylindrical grinder, because when grinding the outer diameter with a cylindrical grinder, the guide column can only grind the center against the center hole. Guide post heat treatment: HRC 58-62; Surface roughness of guide pillar: Ra0.8, Ra 1.6? Guide posts are generally cylindrical with shoulders and generally have oil grooves. The number of oil grooves increases with the extension of the guide post, and the maximum is generally 8.

Guide sleeves in standard parts of automobile dies are often used for drilling and boring. Generally known as drill sleeve for drilling and guide sleeve for boring cutter bar, it is used to ensure that the drill bit or cutter bar will not deviate during cutting, so as to improve the dimensional accuracy and position accuracy of the hole to be machined.
