Description

Technical Field

[0001] This utility model relates to the field of mold trimming technology, and more specifically, to an upper cutting device. Background Technology

[0002] When the scrap material cut off after trimming on the trimming die is large, it is not easy for the scrap material to slide out of the trimming die, nor is it easy to collect the scrap material. Therefore, larger and longer scrap materials need to be cut off. Generally, the trimming die completes the trimming and scrap cutting in one stroke. That is, after the upper die trimming insert moves downward and cooperates with the lower die trimming to complete the trimming, the upper die trimming insert continues to move downward and cooperates with the lower die scrap cutter to complete the scrap cutting. In order to eliminate the interference between the upper die trimming insert and the lower die scrap cutter, a stepped cutting edge must be set on the upper die trimming insert. In this way, during trimming, tearing gaps, burrs and other trimming defects will be formed at the junction of the stepped cutting edges of the upper die trimming insert, which will affect the surface quality of the parts.
