Description

Cold Stamping Die

technical field

The utility model relates to a stamping die, in particular to a cold stamping die which can be automatically demolded and is convenient for taking out products.

Background technique

With the development of science and technology, the popularity of electronic products such as mobile phones and tablet computers has become more and more widespread, and the output of mobile phones has been increasing year by year. The existing mobile phone middle plate is usually made of aluminum alloy material through die-casting to make a semi-finished product, and then the semi-finished product is processed into qualified mobile phone accessories through stamping, cutting off material, punching, oxidation and other processes. Therefore, stamping dies are required in the stamping and cutting process. Generally, the mobile phone aluminum plate stamping die includes an upper template, an inner stripper plate and a lower template. During stamping, the inner stripper plate and the lower template clamp the semi-finished mobile phone aluminum plate. The remaining aluminum material is stretched out, and then the remaining material is cut by pushing the upper template downward to obtain the aluminum plate of the mobile phone; however, in the actual production process, because the upper template has a hollow area, after cutting, the entire aluminum plate of the mobile phone is easily broken It is held in the hollow area of the upper formwork, so it needs to be taken out manually, which not only makes it difficult to take out, reduces production efficiency, but also easily crushes the fingers of workers, resulting in production accidents.

Utility model content

Detailed ways

In order to describe the technical content, structural features, and achieved effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

As shown in Figures 1 to 4, the utility model cold stamping die 100 includes an inner stripping plate 1, an upper template 2, a lower template 3, a backing plate 4, a bearing plate 5, an ejector plate 6, an ejector pin 7, an elastic The element 8 and the pressing plate 9, the elastic element 8 is a compression spring. The lower formwork 3 is fixed on the carrier plate 5, the upper formwork 2 has a hollow area 21, the inner stripper plate 1 is located in the hollow area 21 and clamps the product 200 with the lower formwork 3 to The remaining material of the product 200 is stretched out below the upper template 2, the upper template 2 is fixed to the backing plate 4, the inner stripping plate 1 is hung on the backing plate 4, and the backing plate 4 is fixed with the pressing plate 9, the ejector plate 6 is placed above the backing plate 4, and the elastic element 8 is arranged between the pressing plate 9 and the ejector plate 6; the lower surface of the pressing plate 9 And the upper surface of the ejector plate 6 is provided with a positioning hole 61 , and the end of the elastic element 8 is placed in the positioning hole 61 . The positioning hole 61 can cover the elastic element 8 to prevent the elastic element 8 from being displaced. The ejector pin 7 slides through the backing plate 4 and abuts against the ejector plate 6 and the inner stripper plate 1 .

As shown in Fig. 1 and Fig. 2 again, support blocks 91 are fixed on both sides between the pressure plate 9 and the backing plate 4, between the two support blocks 91, the pressure plate 9 and the backing plate 4 An accommodating cavity 92 is formed, and the ejector plate 6 and the elastic element 8 are disposed in the accommodating cavity 92 . The support block 91 is provided, on the one hand, the backing plate 4 and the pressing plate 9 can be connected and fixed, and on the other hand, the accommodating cavity 92 can be formed, so as to accommodate the ejector plate 6 and the elastic element 8 .

Referring to FIG. 3 again, the bearing plate 5 is provided with a guide column 51 , and the upper template 2 is provided with a guide hole 22 , and the guide column is inserted into the guide hole 22 . The guide column 51 is provided to play a guiding role when the upper die plate 2 goes down, so as to ensure the accuracy of stamping.

Referring to Fig. 3 and Fig. 4 again, a connecting pin 12 is provided between the inner stripping plate 1 and the backing plate 4, and a through hole 41 is provided on the surface of the backing plate 4, and the through hole 41 is fixed inside. There is a sliding sleeve 42 that runs through the backing plate 4, one end of the connecting pin 12 is fixed to the inner stripper plate 1, the other end of the connecting pin 12 slides through the sliding sleeve 42 and the nail head is in contact The surface of the sliding sleeve 42 in the through hole 41 of the backing plate 4 . By setting the connecting pin 12, when the nail head of the connecting pin 12 is in conflict with the backing plate 4, the inner stripper plate 1 can only rise relative to the backing plate 4 but not relative to the backing plate 4 Move down, so that in the process of cutting the remaining material of the upper template 2, the inner stripper plate 1 is always pressed on the product 200, and when the upper template 2 rises, the inner stripper plate 1 Then the upper template 2 can be moved relative to the upper template 2 .

Based on the above, the working process of the cold stamping die 100 of the present invention is described in detail below, as follows:

First, place the semi-finished product 200 on the lower formwork 3, and then drive the upper formwork 2 and the inner stripper plate 1 to move downward through the press plate 9, so that the inner stripper plate 1 and the lower formwork 3 Close the mold, thereby pressing and holding the product 200 of the semi-finished mouth. When the pressing plate 9 continues to move down, due to the effect of the connecting pin 12, the inner stripping plate 1 remains on the lower template 3 plywood, and The backing plate 4 and the lower template 3 continue to move downwards. At this time, the ejection pin 7 abuts against the ejection plate 6, thereby compressing the elastic element 8, and the elastic element 8 moves toward the ejection plate 6. The ejector pin 7 provides a pressure against the inner stripper plate 1 so that the inner stripper plate 1 presses the product 200; at the same time, the lower template 3 has more than 200 products on the periphery of the inner stripper plate 1 The material is stamped and cut. After the stamping is completed, the pressing plate 9 drives the backing plate 4 and the upper template 2 to move upwards. At this time, due to the elastic recovery force of the elastic element 8, the inner stripping plate 1 remains attached to the lower template 3, that is, the inner stripping plate 1 relatively protrudes from the upper template 2. At this time, it is equivalent to making the product 200 leave the hollow area 21. After continuing to move upward for a certain distance, the inner stripping plate After the pressing surface of the plate 1 is fully protruded from the upper mold plate 2, the product 200 can be completely separated from the hollow area 21 and taken out smoothly.

Compared with the prior art, the utility model is provided with an ejector plate 6 on the backing plate 4, an elastic element 8 is arranged between the ejector plate 6 and the pressing plate 9, and an ejector pin is arranged. 7. Make the ejector pin 7 slide through the backing plate 4 to be in contact with the ejector plate 6 and the inner stripper plate 1, so as to use the elastic force of the elastic element 8 during punching, The inner stripper plate 1 is pressed against the product 200, and after the stamping is completed, the inner stripper plate is pushed out of the upper template 2 by using the elastic recovery force of the elastic element 8, so that the product 200 is detached The upper template 2 prevents the product 200 from being stuck in the hollow area 21 of the upper template 2 after stamping and cannot be taken out; therefore, the utility model has the advantages of automatic demoulding, which facilitates the removal of the product 200 and effectively improves production efficiency .

What is disclosed above is only a preferred example of the utility model, and of course the scope of rights of the utility model cannot be limited with this. Therefore, equivalent changes made according to the patent scope of the utility model still belong to the scope covered by the utility model .
