Through the driving of the telescopic cylinder, the whole stripping process can be completed under the control of mechanization and automation.

[0024] The output end of the telescopic cylinder 2 is connected to the first sliding block 3, and the telescopic action of the telescopic cylinder 2 determines the horizontal movement of the first sliding block 3. When the telescopic cylinder 2 is retracted, the first sliding block 3 drives the horizontal movement of the connecting rod 8, thereby driving the movement of the sliding seat 9 and the third sliding block 11, and finally realizing part of the stripping action. The stroke of the telescopic cylinder 2 can be adjusted according to the requirements of the stripping process, so as to ensure that the sliding block 3 accurately completes the stripping task.

The first limiting part 4 functions to guide the inclined movement of the second sliding block 5 along the direction of the limiting block 7, so as to make the second sliding block 5 separate from the oil port 1 of the oil collector and complete the core pulling and stripping. The second sliding block 5 is provided with a core rod extending into the oil port 1 for forming the inner wall of the oil port 1.

[0027] The second limiting part 6 is provided on both sides of the bottom of the second sliding block 5, and the limiting block 7 matched therewith is provided on the second limiting part 6. The limiting block 7 is fixed on the mold plate and functions to fix the movement path of the second sliding block 5. When the first sliding block 3 moves horizontally, the second sliding block 5 moves obliquely along the direction of the limiting block 7 under the action of the first limiting part 4, and finally separates from the oil port 1 to complete the stripping.
