Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 1, 2, 3, 4, and 5, a hemming molding mechanism for a mold includes a die module including an upper die unit and a lower die unit. Go up the mould unit and include clamp plate 1, the downside both ends department of clamp plate 1 all is fixed with a connecting block 2, all installs direction hem piece 3 and connecting block 2 on every connecting block 2. Briquetting 4 and connecting block 2 fixed connection, direction hem piece 3 and connecting block 2 sliding connection, direction hem piece 3 and briquetting 4 also sliding connection. An upper template 5 is fixed on the lower side of the pressing plate 1, and the upper template 5 is positioned between the two pressing blocks 4. When the upper die unit is pressed down, the upper die plate 5 is firstly contacted with the product 7 and presses the product, so that the product 7 is prevented from running in the flanging process.

The die module further comprises a lower die unit, wherein two lower die supporting blocks 6 are arranged on the lower die unit, the positions of the two lower die supporting blocks 6 correspond to the positions of the two pressing blocks 4, the lower die unit is not shown in the drawing, and only the lower die supporting blocks in the lower die unit are shown.

The lower end of one side of the guide flanging block 3 close to the pressing block 4 is provided with a first bending inclined surface 8, the upper side of the first bending inclined surface 8 is provided with a vertical surface 11, and the vertical surface 11 is perpendicular to the upper surface of the lower die supporting block 6. When flanging and edging are carried out, a product 7 is placed on the lower die unit, the edge of the product 7 is bent by 90 degrees, the bent edge is parallel to the vertical surface 11, but the bent edge is not on the same plane with the vertical surface 11, a small distance exists between the bent edge and the vertical surface 11, the specific distance can be set according to the thickness of the product 7, and in order to ensure that the top of the 90-degree bent edge is contacted with the first bending inclined surface 8 when the upper die unit is pressed downwards, the 90-degree bent edge is pressed inwards through the first bending inclined surface 8. The upside of perpendicular 11 is provided with the second inclined plane of bending 12, and the upper end of the second inclined plane of bending 12 and the lower extreme parallel and level of briquetting 4, the second inclined plane of bending 12 are the arc surface, and are the interior concave surface.
