Mold structure for preventing pressed damage to part and upper die for preventing pressed damage to part

Abstract

The invention discloses a mold structure for preventing pressed damage to a part. The mold structure for preventing pressed damage to a part comprises an upper die (20) and a lower die (10) which arematched with each other, wherein the upper die (20) is provided with an upper die lower surface facing the lower die (10); the lower die (10) is provided with a lower die upper surface facing the upper die (20); each of the upper die lower surface and the lower die upper surface is provided with a processing region; the processing regions correspond to an incoming material (200); the upper die lower surface and / or the lower die upper surface is / are at least partially provided with an avoiding region outside the processing regions; and the distance between the avoiding regions of the upper dielower surface and the lower die upper surface is greater than the distance between the processing regions. When the upper die lower surface and the lower die upper surface approach to each other, dueto the existence of the avoiding regions, the part can be accommodated in a space corresponding to the avoiding regions, so that the secondary pressed damage is avoided.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a mold structure for preventing parts from being crushed and an upper mold for preventing parts from being crushed. Background technique [0002] Please refer to Figure 1-2 , figure 1 Schematic diagram for the working of the mold on the fine blanking machine; figure 2 It is a schematic diagram when there is a foreign object between the upper mold and the lower mold of the mold. [0003] Such as figure 1 As shown, the fine blanking machine clamp is equipped with a mold, the mold includes an upper mold 02 and a lower mold 01, the incoming material 002 is transported to the upper surface of the lower mold 01, and the lower worktable pushes the lower mold 01 to move upward for a certain distance. figure 1 position, that is, when the incoming material 002 is in contact with the lower surface of the upper die 02, it will continue to push the upper die 02 and the upper worktable t...

AI Technical Summary

Problems solved by technology

[0006] The part 001 is left between the upper die 02 and the lower die 01. The height of the part 001 is smaller and slightly larger than the height of the incoming material 002. At this time, although the part 001 first touches the lower surface of the upper die 02, it is in contact with the incoming material 002. The position difference to the lower surface of the upper die 02 is not obvious. At this time, it is difficult for the position sensor to detect the slight height difference. The fine blanking machine tool will continue the stamping operation, which will crush the part 001. The crushed part 001 is in the air blowing pipe 03 Under the blowing of the mold, it will fall out of the mold again and fall into other qualified parts, causing serious quality risks
