Abstract
The invention discloses an accurate-positioning injection mould with a self-lubricating guiding column. The accurate-positioning injection mould with the self-lubricating guiding column comprises a front mould body and a rear mould body. The rear mould body comprises a rear mould plate, a rear mould fixing plate, a rear mould support and a rear mould base. An ejector plate is movably disposed between the rear mould fixing plate and the rear mould base. The guiding column is disposed in the ejector plate. A plurality of annular grooves are formed in the external circumference of the guiding column of the ejector plate. Solid lubricants are inlaid into the annular grooves. A plurality of accurate-positioning guiding rods are disposed between a front mould plate and the rear mould plate. During usage of the injection mould, the guiding column makes friction of the solid lubricants and a mould base occur through friction heat, and an excellent condition of oil and powder coexistence lubrication is formed, so that the ejector plate guiding column is protected against abrasion, the solid lubrication property is permanent, the hardness and abrasion resistance of the ejector plate guiding column are effectively improved, and the service life is greatly prolonged; and the accurate-positioning guiding rods of the injection mould are simple in structure, convenient to dismantle, accurate in positioning and capable of being applied and popularized.
