Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-2 The utility model provides the following technical solution: a pneumatic oil injection mold for an automobile wheel hub unit, comprising an oil injection mold body 12 and a connecting seat 1.

[0024] Among them, the right side of the connecting seat 1 is fixedly connected to the side frame 2, the front and rear sides of the top of the side frame 2 are both screwed with the first screw joint 3, the inner side of the front first screw joint 3 is threadedly connected to the cleaning roller 4, and the inner side of the rear first screw joint 3 is threadedly connected to the water-absorbing roller 5. The front and rear sides of the top of the side frame 2 are both provided with a first thread groove, the first thread groove is adapted to the thread strip on the outer side of the first screw joint 3, the cleaning roller 4 is a cloth cleaning roller, and the water-absorbing roller 5 is a sponge water-absorbing roller.

[0025] It can be explained in the above embodiments that the cleaning roller 4 and the water absorbing roller 5 can be flexibly screwed, disassembled and installed, and the arrangement of the cloth cleaning roller can achieve a better cleaning effect, while the arrangement of the sponge water absorbing roller can achieve a more excellent water absorbing effect.

[0026] In addition, a rotary pneumatic component for automatic rotation and automatic pushing is fixedly connected to the upper surface of the connecting seat 1. The rotary pneumatic component includes a servo motor 6 arranged perpendicular to the connecting seat 1. The output shaft of the servo motor 6 is coaxially connected to a rotating disk 7. The upper surface of the rotating disk 7 is fixedly connected to a cylinder 8. The output shaft of the cylinder 8 is connected to a detachable oiling component.

[0027] In this embodiment, the servo motor 6 can perform precise rotational driving, while the cylinder 8 can perform the pushing process.

[0028] In addition, the detachable oiling assembly includes a screw seat 9, the lower surface of the screw seat 9 is connected to the output shaft of the cylinder 8, the inner side of the screw seat 9 is threadedly connected to a second screw joint 10, and the top of the second screw joint 10 is fixedly connected to an oiling head 11.
