The existing patent is a refrigerator door panel punching die. The patent authorization number CN214520676U provides a limit die base and a movable hole die to facilitate the staff to adjust the position of the punching hole, thereby facilitating subsequent punching processing, and the operation is simple, the time required for adjustment is short, and it is beneficial to improve processing efficiency.

[0004] However, in patent authorization No. CN214520676U, the position of the movable hole die is manually adjusted through an adjustment mechanism, and the scale on the scale reference ruler can be used to assist the adjustment during the adjustment process, and then the limit die holder is manually pushed by hand to adjust the position of the limit die holder. However, the refrigerator door panel punching die, however, the die is not configured to collect the discarded mounting plate parts under the punching holes, resulting in a large amount of discarded parts piled up on the processing platform, and the workpiece does not have the function of automatic discharging after the stamping is completed, so we proposed a stamping die for refrigerator parts to solve the above-mentioned problems.
