Stamping die capable of achieving easy material returning of lower die

Abstract

A stamping die capable of achieving easy material returning of a lower die comprises a female die, a male die, a blank holder and a material returning rod. The female die is provided with a first forming side face, and the male die is provided with a second forming side face; a vertical receding groove is formed in the second forming side face of the male die; the material returning rod horizontally penetrates through the blank holder; and in the state that the female die and the male die are matched to extrude a plate blank into a formed part, a vertical space for forming the side face of the plate blank is arranged between the first forming side face and the second forming side face, and one end of the material returning rod is located at the bottom of the formed part and horizontally penetrates through the vertical space into the vertical receding groove. By means of the stamping die, the blank holder is provided with the horizontally-penetrating material returning rod, so that the formed part arranged on the male die in a sleeving manner can be conveniently returned. According to the stamping die, the production efficiency is improved, safety and reliability are achieved, and the technical problems that in the prior art, the male die is tightly arranged on a formed part in a sleeving manner, if manual material returning is conducted after stamping is completed, it is very difficult, material returning of a lower die is inconvenient, and the production efficiency is affected are solved.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a stamping die with an easy-to-return lower die. Background technique [0002] The stamping die includes an upper die and a lower die, wherein the upper die is provided with a die, and the lower die is provided with a punch. The die and the punch cooperate to stamp the blank to form a formed part. Usually, the formed part is easily embedded in the die , so the upper mold is usually equipped with a vertical knockout to return the material. [0003] However, in the prior art, the molded part will also be tightly set on the punch. If the material is manually returned after the stamping is completed, it will be very difficult. The return of the lower die is inconvenient, which affects the production efficiency. Contents of the invention [0004] The object of the present invention is to provide a stamping die with easy return of the lower die, so as to alleviate the technical probl...
