Problems solved by technology

[0006] Although the continuous die for the shielding case solves the disadvantages of low production efficiency and high labor cost of manufacturing the shielding case by using a single punch mold in the traditional process, the design of the continuous die for the shielding case is complicated and the steps are cumbersome, resulting in high design and manufacturing costs, and it is difficult to apply to Manufacture of shielding covers with special structures such as openings on both sides

Embodiment 1

[0073] A kind of double-hole shield progressive mold of the present invention such as Figure 1-13 As shown, it includes an upper mold base 101, an upper mold 103, a stripper plate, a lower mold 104 and a lower mold base 102. The special feature is that the upper mold 103, the stripper plate and the lower mold 104 are assembled in sequence to form a punching guide hole station 201, half-cutting station 202, stretching station 203, double-sided punching station 204, double-sided hole flanging station 205, first flanging flattening station 206, second flanging flattening station 207, punching side notch station 208, punching down shielding cover station 209.

[0074] The double-sided punching station 204 punches holes from the outside to the inside of the stretched part, including the punching and stripping sliders 401 arranged on both sides of the upper die 103, and the punching and stripping slides on both sides of the stripper plate. Slide block 402, punching and stripping s...

Embodiment 2

[0079] A double-hole shield progressive die of the present invention has the same main structure as that of the above-mentioned embodiment 1, and the difference lies in:

[0080] The double-side hole flanging station 205 flangs the drawn part from the outside to the inside, including the three-stage punch 501 of the inner slide block of the flanging lower die on both sides of the upper die 103 and the flanging and stripping slide block punch 502, The flanging and stripping slider punch 502 is arranged on the inner side of the third-stage punching 501 of the slider in the flanging lower mold;

[0081] The secondary punch 503 of the inner slide block of the flanging lower die which is arranged on both sides of the lower die 104, the inner slide block of the flanging lower die which is arranged in the middle of the lower die 104, and the bottom of the inner slide block of the flanging lower die The slide block resetting device 508, the third-stage punch 501 of the inner slider of...

Embodiment 3

[0090] A double-hole shield progressive die of the present invention has the same main structure as that of the above-mentioned embodiment 1, and the difference lies in:

[0091] The first flanging flattening station 206 is to flatten the flanging 302 from the inside to the outside of the drawn part, including the first flanging flattening punch 601 arranged on the upper die 103, and the first flanging arranged on the stripper plate. The flattening punching hole and the first flanging flattening block 602 arranged on the lower die 104, the first flanging flattening punch 601 passes through the first flanging flattening punching hole, the first flanging flattening block 602 is provided with The first flanging flattening block 603 , the first flanging flattening block 603 is provided with a first side hole protection protrusion 604 , and the bottom of the first flanging flattening block 602 is provided with a first reset device 605 .

[0092] During operation, the upper mold 103...

Abstract

The invention relates to the technical field of dies, in particular to a double-hole shielding cover progressive die. The double-hole shielding cover progressive die comprises an upper die holder, an upper die, a stripper plate, a lower die, a lower die holder, and a punching pilot hole station, a half sectioning station, a stretching station and a shielding cover punching-off station which are assembled correspondingly, wherein the upper die, the stripper plate and the lower die are correspondingly assembled with the punching pilot hole station, the half sectioning station, the stretching station, a double-side punching station, a bilateral hole turnup station, a first turnup flattening station, a second turnup flattening station, a punching side notch station and the shielding cover punching-off station which are formed sequentially. During actual production, production can be performed only by placing a material belt on the lower die, all the procedures are finished in the die, andfull automation of the whole flow is realized, so labor cost is reduced, the defective rate of the shielding covers is low, production efficiency is high, and the double-hole shielding cover progressive die is suitable for production of the shielding cover with side holes on the two sides.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a progressive mold for a double-hole shielding cover. Background technique [0002] With the rapid development of science and technology, the application of various high-tech electronic shielding covers is becoming more and more popular, but at the same time it also brings many problems, such as the electromagnetic interference problem encountered in the use of electronic shielding covers, which not only interferes with The normal use of the electronic shield also has adverse effects on the surrounding environment. [0003] In the existing technology, in the protection design of EMI (Electromagnetic Interference, electromagnetic interference) and ESD (Electro-Static discharge, electrostatic discharge) of some current equipment, one of the main means is to shield the interference source with a shielding cover, and Devices susceptible to interference are protected and cut off from t...
