Description

Technical Field

[0001] The utility model relates to the technical field of molds, and more precisely to a blanking mold applicable to workpieces with complex shapes. Background Art

[0002] The process of separating a sheet along a closed contour line and using the material inside the contour line as a blanked part is called blanking, and the mold for completing the blanking process is called a blanking die.

[0003] When blanking and stamping a workpiece with a complex shape, after the stamping is completed, the workpiece needs to be taken out before the staff can perform the stamping of the next workpiece. The stamped workpiece is generally taken out by material ejection prevention. However, after the workpiece is ejected from the mold, there will be a height difference between the mold and the collection tank. For workpieces with complex shapes, when falling from this height, they will be scratched and worn, resulting in a decrease in the accuracy of the workpiece. Therefore, a blanking mold for safely taking out workpieces with complex shapes is required.

[0004] In view of this, the utility model provides a blanking mold applicable to workpieces with complex shapes. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned disadvantages and provide a blanking mold applicable to workpieces with complex shapes that can safely take out workpieces with complex shapes.

[0006] Therefore, the utility model provides a blanking mold applicable to workpieces with complex shapes, including a mold base. A support frame is fixedly installed at the top of the mold base. A lower mold is fixedly installed at the top of the support frame. A stamping hole is opened at the top of the lower mold, and the stamping hole is used for stamping and forming the workpiece. An outlet is opened at the bottom of the stamping hole and is connected. An outlet plate is arranged at the bottom of the lower mold. A reset column is slidably installed inside the lower mold. The bottom of the reset column penetrates the lower mold and is hinged to the top of the outlet plate. A spring-back assembly is arranged on the outer surface of the reset column, and the spring-back assembly is used for spring-back reset after the reset column moves downward. A blanking component is arranged at the top of the lower mold, and the blanking component is used for stamping and forming the material.

[0007] As a further improvement of this technical solution, the blanking component includes a docking cylinder fixedly installed at the top of the lower mold. A docking column is slidably installed inside the docking cylinder. A docking plate is fixedly installed at the top of the docking column. A connecting column is fixedly installed at the top of the docking plate. A buffer spring is installed on the outer surface of the connecting column. An upper mold is slidably installed at the top of the connecting column. A stamping model penetrating to the bottom of the docking plate is installed at the bottom of the upper mold.

[0008] As a further improvement of the technical solution, the elastic component includes a notch opened inside the lower die. A reset spring is installed at the bottom of the inner wall of the notch. A connecting ring is installed at the top of the reset spring. The connecting ring is fixedly installed on the outer surface of the reset column.

[0009] As a further improvement of the technical solution, the discharge plate is hinged in the middle of the support frame. The discharge plate is installed at the bottom of the punching hole and the discharge port. After the workpiece formed by the punching hole falls from the discharge port, it is picked up.

[0010] As a further improvement of the technical solution, the height of the part of the reset column located at the top of the lower die is higher than the height of the docking cylinder. When the docking plate falls, it will abut against the top of the reset column, causing the reset column to move downward.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. In the blanking die applicable to workpieces with complex shapes, when blanking and forming a workpiece with a complex shape, the upper die is connected to the driving device. When the driving device is started, it drives the lower die and the docking plate to move downward. When the bottom of the docking plate abuts against the top of the reset column, the punching model at the bottom of the upper die also abuts against the material on the punching hole at the top of the lower die, cutting the material into a workpiece with a complex shape. The reset column resists and moves downward, pressing down and opening the discharge plate, so that the cut workpiece falls from the discharge port at the bottom of the punching hole onto the discharge plate and flows out, picking up the blanking of the cut workpiece with a complex shape. When the upper die moves upward, the reset column is no longer subjected to downward extrusion, and the reset spring resets the reset column. Repeating like this can pick up the blanking of each cut workpiece, reducing the situation of workpiece blanking collision. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] When blanking and stamping a workpiece with a complex shape, after the stamping is completed, the workpiece needs to be taken out before the staff can perform stamping on the next workpiece. Generally, the stamping workpiece is taken out by being ejected by materials. However, after the workpiece is ejected from the mold, there will be a height difference between the mold and the collection tank. For workpieces with complex shapes, when dropping from this height, they will be scratched and worn, resulting in a decrease in the accuracy of the workpiece. Therefore, a blanking die for safely taking out workpieces with complex shapes is required.

[0021] As Figure 1 shown, the device includes a mold base 1. A support frame 11 is fixedly installed at the top of the mold base 1. A lower mold 2 is fixedly installed at the top of the support frame 11. A stamping hole 21 is opened at the top of the lower mold 2. The stamping hole 21 is used for stamping and forming the workpiece. A discharge port 22 communicating with the bottom is opened at the bottom of the stamping hole 21. A discharge plate 3 is arranged at the bottom of the lower mold 2. A reset post 4 is slidably installed inside the lower mold 2. The bottom of the reset post 4 penetrates through the lower mold 2 and is hinged to the top of the discharge plate 3. A rebound assembly 41 is arranged on the outer surface of the reset post 4. The rebound assembly 41 is used for rebounding and resetting the reset post 4 after it moves downward. A die dropping assembly 5 is arranged at the top of the lower mold 2. The die dropping assembly 5 is used for stamping and forming the material.

[0022] When using the mold to process and form a workpiece with a complex shape, the lower mold 2 is installed at the top of the support frame 11. The die dropping assembly 5 at the top of the lower mold 2 can move downward through a driving device, so that the die dropping assembly 5 performs die dropping stamping on the material placed on the stamping hole 21 at the top of the lower mold 2, and stamps and forms the workpiece with a complex shape. And when the die dropping assembly 5 moves downward, it will abut against the top of the reset post 4, causing the reset post 4 to move downward and press the discharge plate 3 hinged at the bottom, so that the workpiece with a complex shape falling from the stamping hole 21 into the discharge port 22 can fall onto the discharge plate 3 inclined downward at the bottom and flow out, achieving the effect of blanking and taking out the workpiece and avoiding scratching and wearing of the workpiece.

[0023] Considering how the die dropping component 5 stamps the material and the problem of forming workpieces with complex shapes, the specific structure of the die dropping component 5 is first disclosed. The die dropping component 5 includes a docking cylinder 501 fixedly installed on the top of the lower die 2. A docking column 502 is slidably installed inside the docking cylinder 501. A docking plate 503 is fixedly installed on the top of the docking column 502. A connecting column 504 is fixedly installed on the top of the docking plate 503. A buffer spring 505 is installed on the outer surface of the connecting column 504. An upper die 506 is slidably installed on the top of the connecting column 504. A stamping model 507 penetrating to the bottom of the docking plate 503 is installed on the bottom of the upper die 506.

[0024] The improvement of this embodiment lies in that: the docking column 502 is slidably installed inside the upper die 506, and the upper die 506 is supported and installed on the top of the docking plate 503 through the buffer spring 505 on the outer surface of the docking column 502. A hole adapted to the stamping model 507 at the bottom of the upper die 506 is opened on the top of the docking plate 503. When the driving device presses down on the top of the upper die 506, the upper die 506 compresses the buffer spring 505, causing the upper die 506 to fit on the top of the docking plate 503 and move downward together. The docking plate 503 is docked inside the docking cylinder 501 on the top of the lower die 2 through the docking column 502 at the bottom. At this time, the stamping model 507 at the bottom of the lower die 2 passes through the docking plate 503 and drops on the material placed on the top of the lower die 2. The upper die 506 continues to descend, and the stamping model 507 is docked into the adapted stamping hole 21 on the top of the lower die 2 to cut the material, so that the complex shape is stamped and formed, achieving the effect of die dropping and cutting and forming the material.

[0025] When the upper die 506 in the prior art cuts the material into workpieces with complex shapes, there is a problem of how to open and close the discharge plate 3 for discharging. Therefore, Figures 2 - 4 The second embodiment of the present invention is shown.

[0026] The specific structure of the spring back component 41 is disclosed again. The spring back component 41 includes a notch opened inside the lower die 2. A return spring 401 is installed at the bottom of the inner wall of the notch. A connecting ring 402 is installed on the top of the return spring 401. The connecting ring 402 is fixedly installed on the outer surface of the return column 4. The discharge plate 3 is hinged in the middle of the support frame 11. The discharge plate 3 is installed at the bottom of the stamping hole 21 and the discharge port 22 to pick up the workpieces formed by the stamping hole 21 after they fall from the discharge port 22.

[0027] The height of the part of the return column 4 located at the top of the lower die 2 is higher than the height of the docking cylinder 501. When the docking plate 503 falls, it will abut against the top of the return column 4, causing the return column 4 to move downward.

[0028] The improvement of this embodiment lies in that the reset post 4 is slidably installed inside the lower die 2, and a notch is formed on the outer surface of the reset post 4 inside the lower die 2, so that a connecting ring 402 can be sleeved on the outer surface of the reset post 4. The reset spring 401 can move downward in the notch, and the reset spring 401 can rebound and reset the reset post 4. The part of the top of the reset post 4 exposed above the top of the lower die 2 is higher than the docking cylinder 501 at the top of the lower die 2. When the upper die 506 and the docking plate 503 descend, they will first press against the reset post 4 to move downward, and then press against the top of the docking cylinder 501 for positioning. When the reset post 4 is pressed against, it will move downward, causing the discharge plate 3 hinged to the bottom of the reset post 4 to rotate downward and open, so as to pick up the workpiece falling from the discharge port 22, avoiding the situation that the workpiece drops and wears, affecting its precision.

[0029] In summary, the working principle of this solution is as follows:

[0030] When a workpiece with a complex shape is die-molded, the upper die 506 is connected to the driving device. When the driving device is started, it drives the lower die 2 and the docking plate 503 to move downward. When the bottom of the docking plate 503 abuts against the top of the reset post 4, the stamping model 507 at the bottom of the upper die 506 also abuts against the material on the stamping hole 21 at the top of the lower die 2, cutting the material into a workpiece with a complex shape. The reset post 4 is pressed against and moves downward, pressing down and opening the discharge plate 3, so that the cut workpiece falls from the discharge port 22 at the bottom of the stamping hole 21 onto the discharge plate 3 and flows out, picking up the blanking of the cut workpiece with a complex shape. When the upper die 506 moves upward, the reset post 4 is no longer subjected to downward extrusion, and the reset spring 401 resets the reset post 4. Repeating this way can pick up the blanking of each cut workpiece and reduce the situation of the workpiece blanking being bumped.
