[0007] When the self-lubricating steel sleeve of the injection molding machine with oil grooves of the technical solution is used, a vertical oil groove and a horizontal oil groove are opened on the inner wall of the steel sleeve, a spiral oil groove is opened on the surface of the steel sleeve, and the vertical oil groove, the horizontal oil groove and the spiral oil groove are connected through the oil hole, so that the lubricating oil can fully lubricate the inner wall and surface of the steel sleeve, improve the lubrication effect, and ensure the service life of the steel sleeve.
[0008] Furthermore, the number of the spiral oil grooves is four.
[0009] Furthermore, the number of the vertical oil tanks is four.
[0010] Furthermore, the transverse oil grooves are respectively connected to the four vertical oil grooves.
[0011] Furthermore, the four oil holes are arranged at the intersection of the transverse oil groove, the vertical oil groove and the spiral oil groove.
