[0002] Injection molding is a method of producing industrial products. Products are usually made of rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting. Injection molding machine (referred to as injection machine or injection machine) is the main molding equipment for making various shapes of plastic products by using thermoplastic or thermosetting material. Injection molding is realized by injection molding machine and mold.

[0003] When using injection mold, we will use the positioning guide column matched with the mold. However, the existing guide column is often used with the guide sleeve on the lower mold, and the friction between the two often occurs. After a long time of friction, the guide column and the guide sleeve will be worn. In order to reduce the friction between the guide column and the guide sleeve, we usually add lubricating oil to the guide column to reduce the friction between the two. However, when adding oil to the guide column, the equipment needs to be stopped for oiling, which will reduce the yield of injection molded plastic products and cause economic losses to the processing plant, and cannot meet the use requirements of the user.
