Abstract

The invention discloses a shielding case progressive die, which comprises an upper die base, an upper baffle, a lower template, and a lower die base. A pre-punching module, a flash module, a middle punching module, a projection point module, a bottom punching module, a trilateral folding module, one-side folding module, two-side folding module, an upper punching module, an idle module, a leveling block, and a two-side shearing module are arranged on the lower template in turn. An upper base plate, the upper baffle, a striper plate, and the lower template are arranged between the upper die base and the lower die base in turn; an auxiliary leveling block is arranged on the striper plate and corresponds to the leveling block on the lower template. A guide post is arranged in the upper baffle in a penetrating mode; a guide sleeve which corresponds to the guide post is arranged in the lower template; an isoheight sleeve is arranged on the upper die base; a delivery error resistant device is arranged inside the upper die base; a spring is arranged between the upper base plate and the upper baffle; and a lifter pin is arranged on the lower die base. The shielding case progressive die has the advantages of higher production rate, better product quality, better product flatness, and higher production safety.

Description

technical field [0001] The invention relates to a continuous mold, in particular to a continuous mold for a shielding cover, which is particularly suitable for the flow-type rapid production of the shielding cover. Background technique [0002] With the rapid development of science and technology, the application of various high-tech electronic products is becoming more and more popular, but it also brings many problems, such as the electromagnetic interference problem encountered in the use of electronic products, which not only interferes with the electronic products The normal use, but also has an adverse impact on the surrounding environment. The function of the shielding cover is to form an electromagnetic shield to prevent electromagnetic interference. [0003] The Chinese patent publication number is CN101227815A, and the invention patent disclosed on July 23, 2008 discloses a shielding cover and its manufacturing method. The shielding cover includes a cover body and...
