The invention relates to a special oil composition for an injection molding machine joint as well as a preparation method and application thereof. The special oil composition for the joint of the injection molding machine comprises the following components in percentage by mass: 0.0-15% of at least one viscosity index improver; 0.1%-1.0% of at least one pour point depressant; 0.05%-2.5% of at least one extreme pressure agent; 0.01%-2.0% of at least one antiwear agent; 0.01%-0.2% of at least one antirust agent; 0.01%-0.15% of at least one metal deactivator; 0.0001% to 0.1% of at least one anti-foaming agent; and 84%-93% of base oil. The special oil composition for the joint of the injection molding machine has the advantages of low odor, excellent extreme pressure wear resistance and anti-foaming performance, and good viscosity-temperature performance, low-temperature performance and corrosion resistance; meanwhile, the special oil composition can be used in a joint system of injection molding machine equipmen
