The telescopic end of the electric telescopic rod 6 is fixedly connected to a rectangular frame 7 located outside the lower end of the inclined push rod 5. A sliding column 8 is fixedly provided on the outer wall of the lower end of the inclined push rod 5. The outer wall of the rectangular frame 7 is provided with a sliding groove 9 that slides with the sliding column 8.

[0022] The slide groove 9 is obliquely opened on the outer wall of the rectangular frame 7 .

[0023] The oiling mechanism includes an oil tank 10 fixedly arranged on the top of the base 1. The top of the oil tank 10 is an open structure. An oil cover 11 is fixedly arranged on the inner wall of the lower end of the oil tank 10. The top of the oil cover 11 is fixedly connected to an oil delivery pipe 12. The side wall of the oil tank 10 is provided with a movable rod 13 that slides with it. The movable rod 13 and the oil cover 11 are located on the same central axis, and one end of the movable rod 13 is fixedly connected to a piston 14 that fits with the inner wall of the oil cover 11, and the other end of the movable rod 13 is fixedly connected to a connecting block 15. A return spring 16 is fixedly connected between the connecting block 15 and the oil tank 10.

[0025] Working principle: When using the inclined ejector tooling for the injection mold, first, add lubricating oil into the oil tank 10. After the injection product is formed, open the upper mold and start the electric telescopic rod 6. The electric telescopic rod 6 moves the rectangular frame 7 at the telescopic end to the right. Since the slide column 8 slides in the inclined slide groove 9, the inclined ejector rod 5 slides upward in the lower mold 3. The top of the inclined ejector rod 5 pushes the injection product in the groove 4 to complete demoulding. At the same time, the oil delivery channel 17 in the inclined ejector rod 5 moves to the inside of the lower mold 3 and below the groove 4.
