[0033] In one embodiment of this application, specifically, the upper mold assembly 2 includes an upper mold body 24 and an offset structure 21. The offset structure 21 is slidably disposed on the upper mold body 24. The offset structure 21 is located on the side of the upper mold body 24 near the fixed die 1.

Because the limiting block 34 is in the release position, there is no contact between the limiting block 34 and the guide 32. The actuator 31 drives the guide 32 to the right until it contacts the fixed die 1 (or until the actuator 31 is fully working). At this time, the drive mechanism drives the upper mold assembly 2 to move downward, and the first guide surface 22 and the second guide surface 33 are not in contact.

One end of the compression reset member 5 is connected with the inner wall of the mounting groove 25, the other end of the compression reset member 5 is connected with the offset structure 21, the stress direction of the compression reset member 5 is consistent with the sliding direction of the offset structure 21, when the first guide surface 22 is in contact with the second guide surface 33, the compression reset member 5 provides a left offset amount, so that the punch block 23 and the side punching structure 4 are in contact to complete the punching; when the first guide surface 22 is not in contact with the second guide surface 33, the compression reset member 5 does not provide the left offset amount, the punch block 23 normally moves downward and is not in contact with the fixed die 1 and the side punching structure 4, so that the punch block 23 is protected from being damaged.

[0038] In one embodiment of the present application, specifically, the fixed die 1 is provided with a weight-reducing structure 6, which is a weight-reducing groove, a weight-reducing hole or a weight-reducing recess, etc., to reduce the overall weight of the fixed die 1.

[0039] The guide 32 has a mounting portion, and the driving member 31 is fixedly connected with the mounting portion.

[0040] In one embodiment of the present application, specifically, the fixed die 1 is provided with a blanking hole, which is communicated with the side punching structure 4, and the diameter of the blanking hole is greater than that of the side punching structure 4, so that the punched device can be directly discharged by falling, avoiding the blockage of the side punching structure 4.
