It is generally a cylindrical shoulder and generally has an oil groove. The guide sleeve is a mold accessory used in conjunction with the guide pin to play a guiding role. There are many types of existing mold guide pins and sleeves, such as:

[0003] Publication number CN211515831U discloses a precision mold guide pin and guide sleeve, which optimizes the setting of the guide sleeve, and sets a large number of V-shaped openings at the bottom of the slide groove to reserve part of the lubricating oil, so that the guide sleeve can store more lubricating oil for lubrication, and the groove cavity flowing between each slide groove is set as a vertical channel, which is conducive to the circulation of lubricating oil and greatly avoids the problem of lubricating oil residue, so that the lubricating oil injected through the filling channel can better lubricate and improve the coordination effect between the guide sleeve and the guide pin. However, there are still disadvantages. First, when lubricating the guide pin, the equipment lubricates the guide pin through the slide groove, but there is a certain gap between the outer side of the guide pin and the slide groove, so that the guide pin cannot be fully lubricated.

[0004] Therefore, we proposed that precision mold guide pins and guide sleeves can solve the above problems well. Utility Model Content
