Types and installation methods of metal terminal mold guide posts
What are the main types of guide posts?
1. According to the different guiding directions, it is divided into: sliding guide post (code SGP), rolling guide post (code SRP).
2. According to the different installation methods, it is divided into: loading and unloading type guide post and press-in type guide post.
3. According to the different places of use, the guide posts are divided into: guide posts for automobile molds, independent guide posts, guide posts for mold bases, and guide posts for strippers. The guide post is a guide element used in combination with components in the mold to ensure that the mold moves with accurate positioning and guides the stroke of the mold. It is generally cylindrical with shoulders, and there are generally oil grooves. The number of oil grooves increases with the length of the guide column. The maximum limit of oil grooves is generally 8.
The role of the guide post The guide post is a guide element that is used in combination with components in the mold to ensure that the mold can move and guide the stroke of the mold with accurate positioning. The material of the guide post is generally made of bearing steel, hot work die steel, easy-carriage iron, etc., and the use of bearing steel SUJ2 is large, which greatly enhances the durability and replaceability of the guide post in terms of guiding performance. The guide post and the assembly form the outer guide post assembly and the inner guide post assembly, which have a beautiful metallic luster. The roundness of the guide post has high requirements. The central hole is mainly used to grind the outer diameter with a cylindrical grinder, because when using a cylindrical grinder to grind the outer diameter, the center hole must be supported by the top to make the guide post rotate. Can be ground. Guide post heat treatment: HRC58-62; guide post surface roughness: Ra0.8, Ra1.6 The guide post is generally cylindrical with shoulders and generally has oil grooves. The number of oil grooves increases with the length of the guide post, and the limit is the most The oil tank is generally 8. The guide sleeves in the standard parts of automobile molds are often used for drilling and boring. Generally, the drill sleeves used for drilling are called drill sleeves, and those used for boring holes are called arbor guide sleeves. Improve the dimensional accuracy and positional accuracy of the machined holes.
Processing of the mounting holes of the guide post & guide sleeve The installation holes of the guide post & guide sleeve should be processed with a boring machine or a coordinate grinder after all other holes are processed and the machining stress is eliminated (re-grinding on the upper and lower sides, etc.). In order to determine the datum of the upper die and the lower die, temporary positioning holes can be machined, and then positioned with pins. Four: Installation of the guide post After cleaning the installation holes, tighten the bolts to fix the guide post.
1. When using multiple needle roller guide post assemblies at the same time, stagger the reference plane of one guide post among the multiple guide posts by 90° to prevent the mold base from being assembled incorrectly.
2. Confirm the verticality of the guide post. (0.01mm/100mm or less)
3. When press-fitting the guide post, please press it slowly by means of a hydraulic press or the like. Using a hammer or other tool to strike and press in may cause the guide post to bend and deform. Insert the guide post into the guide sleeve. (Please align the matching marks and marks for the needle roller guide bushes) Place the parallel block on the lower die seat, and then install the upper die seat.・Slide the guide bush and check for interference.・Remove grease and dirt on the bonding surface with solvent, pour anaerobic adhesive into the bonding groove of the guide bush, and then insert it into the mounting hole. Please cure the adhesive to prevent the guide sleeve from popping out of the upper die holder (3 to 6 hours at room temperature). Installation of the stopper The movable stopper... After the adhesive is completely cured, insert the spring and the fixing block, and then rotate the hexagonal guide shaft of the movable stopper RSTM and STM with a wrench to install. Fixed stopper... After the adhesive is completely cured, insert the spring and fixed block, and install the fixed stoppers RSTK and STK. Assembly and disassembly of the guide post.
