Abstract

The invention provides an aluminum stamping die with exhausting structure. The aluminum stamping die comprises an upper die seat mechanism, a lower die seat, a male die, a demolding insert, a forminginsert, an air pressure buffering mechanism and an exhausting channel. The upper die seat mechanism is slidably connected to the lower die seat, the male die and the demolding insert are arranged on the upper die seat mechanism, and a groove is formed in the top of the lower die seat. The groove is formed under the male die, the forming insert is arranged at the inner bottom of the groove, and theair pressure buffering mechanism is arranged between the forming insert and the side wall of the groove, and communicates with the forming insert. The exhausting channel is arranged in the lower dieseat. According to the aluminum stamping die, by means of the air pressure buffering mechanism, air in a sealed cavity is buffered and released through the exhausting channel, so that instant air pressure borne by an aluminum workpiece and the forming insert is reduced, it is ensured that the aluminum workpiece does not deform, and therefore the yield of the aluminum workpiece is increased; and the forming insert is protected against impacting and bursting, and therefore the service life of the die is prolonged, and the die cost is reduced.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to an aluminum stamping die with an exhaust structure. Background technique [0002] The aluminum material is a soft metal material. During the stamping process, a sealed cavity will be formed between the aluminum material and the lower die insert. Due to the stamping of the aluminum material by the punch, the air in the lower die insert will be compressed sharply, which will easily lead to aluminum The deformation of the aluminum workpiece will cause the insert of the lower mold to burst after long-term use, making the mold invalid, which not only reduces the yield of aluminum workpieces, but also increases the investment in mold costs. Contents of the invention [0003] In view of this, the present invention provides an aluminum stamping die with an exhaust structure, which solves the problem in the prior art that the gas in the stamping die is rapidly compressed and the d...
