Detailed ways

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

Please refer to FIG. 1 and FIG. 2 , the side punching die of the present invention includes an upper die 10 and a lower die 20 matched with the upper die 10 .

The upper mold 10 includes an upper mold base 11 , an upper driving block 12 is provided on the lower surface of the upper mold base 11 , and an upper stripping plate 13 is provided in the middle of the upper mold base 11 .

The lower mold 20 includes a lower mold base 21 , between the upper driving block 12 and the lower mold base 21 a resisting block 22 and a lower driving block 23 are arranged on the lower mold base 21 . An elastic element 24 is installed in the lower driving block 23 , specifically, a receiving cavity 231 is arranged in the lower driving block 23 , and the elastic element 24 is installed in the receiving cavity 231 . The lower driving block 23 is provided with a lower stripping plate 25, and the lower stripping plate 25 is provided with a forming block 26 and a push block 27 movably mounted on the forming block 26 in the horizontal direction. The resisting block 27 is adjacent to the elastic element 24 , and a punch 28 is fixedly mounted on the resisting block 27 . Specifically, the forming block 26 is provided with a mounting groove 261 , one end of the punch 28 is fixedly installed in the resisting block 27 , and the other end is accommodated in the mounting groove 261 .

A plurality of wear-resistant plates 29 are arranged around the lower driving block 23 , and the wear-resistant plates 29 are respectively arranged between the resisting block 22 and the lower driving block 23 and between the lower driving block 23 and the lower mold base 21 .

In this embodiment, the upper driving block 12 is a wedge driving block, and the lower driving block 23 has a slope matching the slope of the wedge driving block.

In this embodiment, the elastic element 24 is a nitrogen spring. The nitrogen spring has a large elastic force, a long service life, and a constant elastic force. The long service life can reduce the number of maintenance of the mold, thereby reducing the total cost of the mold.

When the upper mold 10 moves downward under the action of pressure, the upper driving block 12 also moves downward thereupon until the upper driving block 12 contacts the lower driving block 23, and the upper driving block 12 pushes the lower driving block 23 in a horizontal position. direction sliding, the lower drive block 23 drives the elastic element 24, the lower stripper plate 25, the forming block 26, the thrust block 27 and the punch 28 to move in the horizontal direction until it contacts the product (not shown in the figure) until the product is formed process, at the same time, the upper driving block 12 continues to push the lower driving block 23 to slide in the horizontal direction, the forming block 26 moves in the opposite direction and pushes the resisting block 27 to move together, and the resisting block 27 moves in the direction of the elastic element 24 Slidingly extrudes the elastic element 24 . The lower driving block 23 drives the elastic element 24, the lower stripping plate 25, the forming block 26, the pushing block 27 and the punch 28 to continue to move in the horizontal direction until the forming process of the product is completed, at this time the elastic element 24 releases the elastic potential energy , the elastic element 24 pushes the push block 27 to move in the horizontal direction, and the push block 27 drives the punch 28 to move, and the head of the punch 28 protrudes from the side of the forming block 26 until the product is punched.

As mentioned above, since the side punching die of the present utility model is provided with an elastic element 24 in the lower driving block 23, after the side punching die molds the product, the elastic element 24 releases the elastic potential energy to push the punch 28 out of the pair. The product realizes punching, and the mechanism characteristics of the side punching die of the utility model can realize the first forming and then punching of the product, thereby improving the product quality.

However, the above is only a preferred embodiment of the utility model, and should not limit the scope of the utility model implementation, that is, all simple equivalent changes made according to the scope of the utility model claims and the contents of the patent specification and modifications, all still belong to the scope of the utility model claims.
