[0030] The flash stamping die for facilitating material removal according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-Figure 7 As shown, according to the embodiment of the utility model, a flash stamping die that is easy to remove materials includes: a base 3, a lower template 2, and an upper template 1; the lower template 2 is arranged on the base 3, and the upper surface of the lower template 2 has a protrusion for cutting the flash of the forging, and a through hole 22 is formed on the lower template 2. A support plate 21 is provided in the through hole 22, and the support plate 21 is connected to a driving unit. The driving unit is used to drive the support plate 21 to make a linear reciprocating movement so that the support plate 21 pushes the forging on the lower template 2. The upper template 1 is arranged on the punching head, and the upper template 1 is arranged opposite to the lower template 2. The punching head is used to drive the upper template 1 to approach or move away from the lower template 2 to cooperate with the lower template 2 to cut the flash of the forging.

[0032] In this embodiment, when placing the forging, the driving unit is in the output state, at which time the forging is placed on the support plate 21, and then the driving unit drives the support plate 21 to move downward, so that the flash of the forging on the support plate 21 gradually contacts the protrusion on the lower template 2, and the support plate 21 is used to drive the forging to descend to contact the protrusion, thereby avoiding the forging being heavily hit against the protrusion during the lowering process due to the thick forging, thereby avoiding damage to the forging, and during the stamping process, the forging is always in contact with the support plate 21, thereby avoiding the forging falling after the flash is removed. The collision phenomenon caused ensures the integrity of the outer surface of the forging. During the downward movement of the support plate 21, the punch head drives the upper template 1 to move downward to approach the lower template 2 until the upper template 1 cooperates with the lower template 2 to complete the cutting of the flash. At this time, the drive unit drives the support plate 21 to move upward, so that the forging is pushed up to leave the lower template 2, and then the forging is picked up by tools such as manipulators, avoiding the phenomenon that the forging is embedded in the lower template 2 after removing the flash, causing difficulty in picking up, speeding up the speed of picking up the forging, and saving time costs.

[0033] The cross-sectional size and shape of the through hole 22 are the same as those of the forging, so that the forging can be embedded in the through hole 22, which is convenient for the flash of the forging to fit with the protrusion, and the support plate 21 is slidably connected to the inner surface of the through hole 22 to increase the supporting area of ​​the forging. That is to say, a concave through hole 22 is provided on the lower template 2 for embedding the forging, which reduces the requirement for the height of the protrusion, and saves the material used to manufacture the lower template 2 while ensuring the stability of the protrusion; in addition, the support plate 21 is slidably connected to the inner surface of the through hole 22, that is, the size of the support plate 21 is close to that of the inner surface of the through hole 22, while ensuring the smoothness of the up and down movement of the support plate 21, the contact surface between the support plate 21 and the forging is increased, and the stability of the forging is increased, so that the forging can maintain balance during the movement, and avoid the forging from tilting and getting stuck inside the through hole 22, thereby achieving the smoothness of the forging moving in the through hole 22.

[0034] The contact surface of the support plate 21 and the forging are matched so that the support plate 21 can stably support the forging, that is, the support plate 21 and the forging are in a meshing state. Due to the complex surface shape of the forging, if a flat support plate 21 is used, the contact surface between the support plate 21 and the forging will be smaller, or the horizontality of the forging cannot be maintained. Therefore, a support plate 21 that matches the forging is used to achieve the stability of the support for the forging and ensure the horizontality of the forging after support.

[0035] The driving unit is a first cylinder 4 . There are multiple first cylinders 4 , and the multiple first cylinders 4 are evenly arranged at the bottom of the supporting plate 21 .

[0036] The plurality of first cylinders 4 are arranged in an S-shaped direction.

[0037] In this embodiment, the first cylinder 4 is fixed on the base 3, and the output end of the first cylinder 4 is fixedly connected to the support plate 21. Multiple first cylinders 4 are arranged at intervals along the length direction of the support plate 21 and arranged in an S-shaped direction. When the width of the support plate 21 is not enough to set two rows, it can be ensured that the first cylinder 4 can support the edge of the support plate 21 to ensure the supporting force of the edge of the support plate 21.

[0038] A plurality of second cylinders 5 are provided on the base 3. The second cylinders 5 are located at both sides of the frame. The second cylinders 5 are used to push the burrs punched down to prevent the burrs from being stuck on the frame.

[0039] In this embodiment, the second cylinder 5 is fixed on the base 3. After the flash is cut off, the output end of the second cylinder 5 is pushed upward to lift the flash. At the same time, the punching head drives the upper template 1 to move upward. When the lifted flash moves to the top of the lower template 2, the flash is taken out by a robot. The flash is pushed by multiple second cylinders 5 to ensure that the flash moves upward horizontally so that the flash can be smoothly taken out from the lower template 2.

[0040] The lower mold plate 2 is formed with the same number of guide holes 25 as the number of the second cylinders 5 , and the output ends of the second cylinders 5 pass through both ends of the guide holes 25 .

[0041] A support plate 51 is provided on the output end of the second cylinder 5 , and the support plate 51 is used to increase the contact area with the flash edge.

[0042] In this embodiment, the second cylinder 5 is located below the lower template 2, and a guide hole 25 is set close to the outer edge of the protrusion, so that the output end of the second cylinder 5 passes through the guide hole 25 to lift the flash. When the output end of the second cylinder 5 is retracted, the support plate 51 is sunken into the guide hole 25 to avoid interference during cutting. The size and shape of the support plate 51 can be set according to the size of the flash to avoid slipping caused by a small contact area between the support plate 51 and the flash when the flash is narrow, thereby ensuring the stability of the flash movement.

[0043] A limiting groove 23 is provided at the bottom of the through hole 22 , and a protrusion 24 is provided on the side surface of the supporting plate 21 . The limiting groove 23 matches the protrusion 24 , and the limiting groove 23 is used to limit the moving range of the protrusion 24 .

[0044] In this embodiment, the limiting groove 23 and the protrusion 24 are both rectangular, and the outer surface of the protrusion 24 fits the inner surface of the limiting groove 23. When the support plate 21 moves upward, the protrusion 24 is slidably connected with the limiting groove 23. The limiting groove 23 guides the protrusion 24, avoiding uneven force on the support plate 21 and tilting caused by uneven gravity at different angles of the forging, thereby ensuring the horizontal state of the support plate 21. The forging structure is complex, so if the gap between the support plate 21 and the inner wall of the through hole 22 is reduced to avoid tilting of the support plate 21, it will cause a problem of great production difficulty. Therefore, the limiting groove 23 and the protrusion 24 are used for guidance, which reduces the gap requirement between the support plate 21 and the through hole 22, thereby reducing the production difficulty.
