As shown in fig. 1 and 2, an embodiment of the present utility model provides a sheet forming mold, which includes an upper mold 1 and a lower mold 2, wherein the upper mold 1 is provided with a male mold 3, the lower mold 2 is provided with a female mold 4, and the female mold 4 and the male mold 3 are disposed vertically correspondingly. The upper die 1 is fixedly arranged, the lower die 2 is movably arranged, and when the lower die 2 moves upwards and the upper die 1 and the lower die 2 are clamped, the male die 3 stretches into the female die 4 and forms a sheet by stamping, so that a product with a preset shape is formed. It should be noted that a molding pattern or the like may be further provided at the corresponding position of the male die 3 and the female die 4 so that the sheet may have a specific pattern, a decorative pattern or the like directly after molding.

Meanwhile, the die in this embodiment further includes a shearing die 5, the shearing die 5 is in an annular structure, and surrounds the outer side of the male die 3, and the bottom end of the shearing die 5 has an annular shearing edge. Wherein, the shearing die 5 is also connected with the upper die 1 or the male die 3, and the shearing die 5 and the sheet material can also move relatively in the process that the lower die 2 drives the female die 4 to move upwards during the stamping forming. When the male die 3 is fully inserted into the female die 4, the shearing edge of the shearing die 5 also contacts the edge position of the sheet, and the edge position of the sheet is sheared under the action of stamping force, so that the sheet is sheared into a preset contour shape while the stamping forming is finished, and the subsequent product assembly and the like are facilitated.

When the die 4 is moved downward and reset after press forming, it can be separated directly from the sheet (based on the engaging force with the punch 3 after the sheet is deformed). At the same time, the sheet needs to be further separated from the punch 3 to enable the sheet to be collected. Based on this, a pushing mechanism is further provided in this embodiment, and specifically includes a pushing plate 6 and a pushing cylinder 7 that drives the pushing plate 6 to move. Wherein, the pushing cylinder 7 is connected with the upper die 1, and the piston rod end of the pushing cylinder 7 is connected with the pushing plate 6, so that the position of the pushing plate 6 can be controlled by means of cylinder expansion.

In this embodiment, the inner edge of the stripper plate 6 is closely attached to the outer side of the cutting edge and is consistent with the shape of the cutting edge, so that the inner edge of the stripper plate 6 pushes the sheet downward along the cutting edge under the action of the stripper cylinder 7, so that the sheet is quickly separated from the punch 3 and blanked downward.

Wherein, can set up receiving mechanism, after die 4 moves down and punch 3 separation, receiving mechanism's receiving plate removes to punch 3 under, then pushes away material cylinder 7 and drives pushing away material board 6 and separate blanking with the sheet, makes the sheet fall into on the receiving plate, and receiving plate removes to the unloading position again and carries out unloading etc. to let smoothly accomplish the sheet unloading after stamping forming and the shearing.

It should be noted that, based on the larger size of the pushing plate 6, four pushing cylinders 7 are provided in the present embodiment, and the four pushing cylinders 7 are synchronously driven, so that the pushing plate 6 pushes the material more horizontally and stably.

Meanwhile, as shown in fig. 3, in this embodiment, the shearing die 5 is movably connected with the male die 3, and a buffer die 8 is also provided, the buffer die 8 is located above the male die 3, the buffer die 8 is made of an elastic material, and the male die 3 can also perform a certain displacement (small section) relative to the buffer die 8. The outer side of the shearing die 5 is provided with a shearing connecting die 13 in a surrounding mode, the shearing connecting die 13 is fixedly connected with the shearing die 5 through a fixing pin, the upper surface of the shearing connecting die 13 is provided with a first connecting pin 14, and the upper surface of the male die 3 is provided with a second connecting pin 15.

After the female die 4 contacts with the male die 3, the female die 4 continuously drives the male die 3 to move upwards, the male die 3 gradually compresses the buffer die 8 through the second connecting pin 15, and the buffer die 8 can apply elastic counter force to the male die 3 in the gradual compression process, so that the male die 3 cannot continuously move after moving to the limit position, and the die can be completely matched with the female die 4. In this process, the shearing die 5 and the shearing connection die 13 also move upwards, and based on the fact that the length of the first connection pin 14 is greater than that of the second connection pin 15, the first connection pin 14 passes through the structural hole of the buffer die 8 to be in contact with the fixed structure, and the shearing die 5 cannot move in the process that the subsequent male die 3 moves upwards for a small period, so that the shearing die 5 moves downwards for a small distance relative to the male die 3, and the redundant sheet at the edge is sheared.

Meanwhile, as shown in fig. 4, it can be understood that after the stamping is completed, the male die 3 is elastically reset under the action of the buffer die 8, and the shearing die 5 also needs to be reset, and the resetting process of the shearing die needs to be moved up a small distance relative to the male die 3, based on this, the shearing connection die is further provided with a spring hole 9, a reset spring 10 is arranged in the spring hole 9, a first end of the reset spring 10 is contacted with a hole bottom of the spring hole 9, a second end is contacted with the upper die 1, and a second end of the reset spring 10 is located below and a first end is located above. By means of the elastic force of the reset spring 10, the shearing die 5 is ensured to move up to a preset position relative to the male die 3 after the male die 3 is reset, the next shearing quality is ensured, and a buffer protection effect can be further achieved during shearing. When the shear die 5 is reset, the upper surface of the shear die is flush with the upper surface of the punch 3.

The inner side wall of the shearing die 5 is provided with a connecting column 11, the outer side wall of the male die 3 is provided with a connecting groove 12 corresponding to the connecting column 11, and the connecting column 11 is movably arranged in the connecting groove 12, so that the shearing die 5 and the shearing connecting die 13 can stably move downwards and reset relative to the male die 3.

As a preferred embodiment, in this embodiment, the shearing blade is provided with blunt ports, which are preferably distributed at the diagonal positions of the shearing blade, and the blunt ports are used to prevent the shearing blade from completely cutting off the redundant part of the sheet, so that the redundant material can remain on the outer side of the male die 3 after the shearing is completed, thereby facilitating the rapid pushing of the stripper plate 6 and ensuring the reliability of sheet demoulding. Since the sheet is not completely cut off at a few small points, the surplus material can be separated conveniently in the following steps.

In summary, by adopting the sheet forming die provided in this embodiment, the stamping forming, shearing and separating of the sheet from the die can be smoothly completed, the reliability of the sheet forming operation is ensured, and the sheet forming die is suitable for pipelined processing.

While the foregoing is directed to the preferred embodiments of the present utility model, it will be appreciated by those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present utility model, and such modifications and adaptations are intended to be comprehended within the scope of the present utility model.
