5. About Guide Components
(1 ) Introduction
Guide Pillar is mold and die components to be used in combination to ensure precise positioning activities guide travel guide elements mold.
Guide Bushes / Guide Sleeves
Mold parts, used in conjunction with the guide posts, play a guiding role in general with the gap is very small, less than the 0.05mm;
Material of guide pillars generally used in bearing steel, hot die steel, easy to iron, etc., and to the amount of bearing steel SUJ2 larger, so that the guide post in durability and performance can change sexual orientation is greatly enhanced. Guide column with components outside the guide column components and assemblies within the guide column, with a beautiful metallic luster.
Pillar shoulder belt is generally cylindrical, generally have oil groove, the number of oil groove of the guide post with lengthened degree increases, up to the limit tank is generally 8.
(2) Classification
Guide Pillars, in accordance with the use of different places, divided into: automotive mold guide column, an independent guide posts, guide posts with mold, stripper plate with guide posts. Not the same in accordance with the direction of the guide is divided into: slide guide column (Code SGP), rolling guide column (Code SRP). Follow the installation in a different way, divided into: loading type push type pillar and pillar.
(3) Angle pins
Oblique angle pillar mold often used typically 20 degrees or 25 degrees two tilt angle of 20 degrees generally use this kind, if the length of the slider is moved a little distance, you can adopt this kind of 25 degrees. If the distance is longer, then we would use hydraulic or pneumatic methods.
( 4 ) Center hole
Roundness pillar there is a very high demand, primarily playing center hole in order to use cylindrical grinder grinding diameter, because the use of the outside diameter of the cylindrical&
