Stamping die of cellphone protective shell

Abstract

The invention discloses a stamping die of a cellphone protective shell. The stamping die comprises an upper die body and a lower die body. The upper die body sequentially comprises an upper die base, an upper padding plate, an upper clamping plate and a stripper plate, and the lower die body sequentially comprises a lower die plate, a lower padding plate and a lower die base. The stamping die is characterized in that a punching die, a bending die, a leveling die and an attaching die are sequentially arranged on the stripper plate. By the adoption of the stamping die, labor cost and mechanical cost are greatly reduced, production stability and production efficiency are improved, and the defective rate can also be reduced.

Description

technical field [0001] The invention relates to a stamping die, in particular to a stamping die for a mobile phone protective case. Background technique [0002] With the continuous advancement of science and technology, the replacement of mobile phone products is getting faster and faster. At present, intelligent touch-screen mobile phones have gradually replaced traditional key-press mobile phones and become the mainstream mobile phone consumer products. It is thinner, so its drop resistance is poor, resulting in a shorter service life. Therefore, users usually put a protective case on the smart touch screen mobile phone to improve the resistance of the mobile phone. However, the current stamping dies for making mobile phone protective cases are generally It consists of a punch and a die, or it can be composed of multiple punches and dies, but only one punching process can be completed in one stroke of the punching machine. This kind of die is not only unstable, but also w...
