[0002] Molds, also called molds or tools, are various devices used to obtain the desired products through injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. In short, molds are tools used to make molded objects. They mainly achieve the processing of the shape of objects by changing the physical state of the molded materials. Molds are known as the "mother of industry" and occupy an indispensable position in industrial production. Mold guide pins are used in molds and are used in combination with components to ensure that the mold moves with precise positioning and guide the mold stroke.

[0003] During the mold opening and closing process, the mold guide pin continuously generates friction with the guide sleeve. In order to reduce the friction between the two, the surface of the guide pin is usually coated with lubricating oil. However, during the repeated use of the mold, the amount of lubricating oil continues to decrease, and the wear rate of the guide pin will also accelerate. The staff is required to lubricate the guide pin regularly, which is cumbersome to operate and the labor cost will also increase. Therefore, a mold guide pin lubrication device is proposed.

When the guide column 16 enters the guide sleeve 12, the guide sleeve 12 squeezes the sealing plug 211 to create a gap between it and the limiting ring 212, and the lubricating oil enters the oil groove 17 to ensure that the amount of lubricating oil in the oil groove 17 is sufficient. After the guide column 16 withdraws from the guide sleeve 12, the second spring 210 drives the sealing plug 211 to close the through hole 29, stop delivering the lubricating oil, and avoid waste of the lubricating oil.

[0030] In this embodiment, specifically: the main body assembly 10 includes a bottom plate 11 and a guide sleeve 12;

[0031] A guide sleeve 12 is fixedly connected to the top of the bottom plate 11 . The guide sleeve 12 is an internal hollow structure and is used to prevent the guide column 16 from moving.
