Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and more specifically, to a stamping die structure with an in-die detection system. Background Technology

[0002] Stamping dies are a special type of equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). However, traditional stamping dies cannot monitor key parameters such as stamping pressure in real time during operation. When abnormalities occur, they cannot be detected in time, which can easily lead to the production of a large number of defective products, reduce production efficiency, and increase production costs.

[0003] Utility model patent CN214470939U discloses a metal stamping die inspection mechanism and system, including a housing and a control panel. A groove is formed on the lower surface of the inner wall of the housing, and sliding blocks are provided on both sides above the groove. A storage box is located above the sliding blocks, and a conveyor belt is located above the storage box. A protective sleeve is provided on the outside of the conveyor belt. First locking blocks are provided on both inner walls of the protective sleeve, and the outer walls of the first locking blocks are fitted with first locking grooves. The first locking grooves are located on both sides of the outer wall of the conveyor belt. Cleaning brushes are provided on both sides of the inner wall of the housing, and the cleaning brushes are connected to the housing by fixing bolts. This metal stamping die inspection mechanism and system facilitates the cleaning of the conveyor belt during use, preventing the device from becoming too dirty and inconvenient to use due to the inability to clean the conveyor belt in a timely manner, thus effectively improving the device's performance.

[0004] While this technical solution has its advantages, most current stamping die structures with in-mold detection systems still have some shortcomings in use. For example, the pressure sensors can only detect the extrusion force during pressing, not the ejection force when the workpiece is ejected. The lack of ejection force detection can easily lead to excessive or insufficient ejection force, affecting workpiece ejection and causing inconvenience to the user. Therefore, we propose a stamping die structure with an in-mold detection system. Utility Model Content

[0005] The purpose of this invention is to provide a stamping die structure with an in-mold detection system to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A stamping die structure with an in-mold detection system includes a moving die and a fixed die. A central groove is provided on the bottom wall of the fixed die, and a slide rail communicating with the outside is provided on the bottom wall of the central groove. Side grooves are provided on both the left and right sides of the central groove. A cylinder is located below the fixed die. The end of the cylinder's telescopic shaft passes through the slide rail and is fixedly mounted with an ejector plate.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-3 This utility model provides a technical solution: a stamping die structure with an in-mold detection system, including a moving die 1 and a fixed die 20. A central groove 21 is provided on the bottom wall of the fixed die 20, and a slide rail 211 communicating with the outside is provided on the bottom wall of the central groove 21. Side grooves 22 are provided on both the left and right sides of the central groove 21. A cylinder 3 is provided below the fixed die 20. The end of the telescopic shaft of the cylinder 3 passes through the slide rail 211 and is fixedly installed with an ejector plate 30. The ejector plate 30 is located inside the central groove 21 and is slidably connected to the central groove 21. Side plates 31 are fixedly installed on both the left and right sides of the mold 0. The side plates 31 are located in the side grooves 22. A pressure sensor 32 is fixedly installed on the top surface of the side plate 31. A top plate 33 is fixedly installed on the top of the pressure sensor 32. A control host 4 is set outside the fixed mold 20. When the cylinder 3 drives the ejector plate 30 to eject the workpiece, the top plate 33 transmits the force to the pressure sensor 32 to realize the real-time detection of the ejection force. The detection data can be transmitted to the control host 4 for easy monitoring, avoiding excessive or insufficient ejection force, and ensuring smooth unloading of the workpiece.

[0031] In this embodiment, during normal stamping, the ejector plate 30 is located in the central groove 21, and the side plate 31 is located in the side groove 22, so that the stamping operation can be carried out normally; the top surface of the top plate 33 and the top surface of the ejector plate 30 are located on the same plane, so that the force applied during pressurization can be applied normally to the top plate 33, and further to the pressure sensor 32; and the top plate 33 is located on one side of the ejector plate 30, so that the top plate 33 and the ejector plate 30 will not affect each other.

[0032] Specifically, the slide 211 is vertically arranged, and the size of the side plate 31 is matched with the size of the side groove 22, so that the ejector plate 30 rises and falls vertically along the slide 211, and the side plate 31 slides stably in the side groove 22, preventing deviation during ejection and improving the stability of the ejection mechanism.

[0033] like Figure 1 As shown, a moving template 10 is fixedly installed on the top of the moving mold 1. The moving template 10 is fixedly installed on the external drive shaft, so that the moving template 10 can be fixed on the external drive shaft, driving the moving mold 1 to move precisely, realizing the mold closing and opening operations of the moving mold 1 and the fixed mold 20, and ensuring the smooth progress of the stamping process.

[0034] like Figure 1 As shown, a fixed template 2 is fixedly installed at the bottom of the fixed mold 20. The fixed template 2 is fixedly installed on the external frame to provide stable support for the fixed mold 20, prevent the fixed mold 20 from shaking during operation, and enhance the stability of the overall structure.

[0035] In addition, a vertically arranged guide hole 221 is provided on the bottom wall of the side groove 22, and a vertically arranged hollow guide rod 34 is fixedly installed on the bottom surface of the side plate 31. The hollow guide rod 34 is located in the guide hole 221 and is slidably connected to the guide hole 221, so that the hollow guide rod 34 slides in the guide hole 221, which guides the movement of the side plate 31, ensures that the side plate 31 moves stably along the preset trajectory, and improves the movement accuracy of the ejection mechanism.

[0036] Specifically, the top of the hollow guide rod 34 extends to the top surface of the side plate 31. The hollow guide rod 34 is a hollow columnar structure, which allows the wiring of the pressure sensor 32 to pass through the inside of the hollow guide rod 34, which facilitates wiring operations, avoids messy wiring, and facilitates later maintenance.

[0037] like Figure 2 As shown, the side plate of the fixed mold 20 is provided with heat dissipation holes 23. The heat dissipation holes 23 are connected to the outside for heat dissipation operation, so that the heat inside the fixed mold 20 can circulate with the outside air through the heat dissipation holes 23 to achieve heat dissipation operation and prevent the internal temperature from being too high and affecting the normal operation of the parts.

[0038] It is worth noting that multiple guide posts 24 are fixedly installed on the upper surface of the fixed template 2. The moving template 10 is fitted onto the guide posts 24 and is slidably connected to the guide posts 24 to ensure the accuracy of the moving mold 1 during movement, improve the accuracy of the mold closing between the moving mold 1 and the fixed mold 20, and ensure the stamping quality.

[0039] It is worth noting that the value detected by the pressure sensor 32 can be transmitted to the control host 4. By setting a corresponding pressure value in the control host 4, when the pressure value detected by the pressure sensor 32 reaches the threshold set in the control host 4, the control host 4 controls the cylinder 3 to stop working. Finally, it should be noted that the pressure sensor 32, control host 4, cylinder 3, corresponding control system and external power supply of this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and adapted controllers and power supplies, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0040] In the initial state of use, the moving mold 1 is mounted on the guide post 24 via the moving template 10 and is in the mold opening position. The fixed mold 20 is fixed to the external frame via the fixed template 2. The ejector plate 30 is housed in the central groove 21. The side plate 31 is embedded in the side groove 22. The hollow guide rod 34 is placed in the guide hole 221. The pressure sensor 32 and the top plate 33 are in the low position.

[0041] An external drive shaft drives the moving template 10 to move the moving mold 1 down along the guide post 24 and close with the fixed mold 20 to complete the stamping. During the process, the heat dissipation holes 23 of the fixed mold 20 achieve internal heat dissipation. During the mold closing process, the pressure sensor 32 detects the downward pressing force of the stamping.

[0042] After stamping is completed, the moving mold 1 moves up and opens the mold along the moving template 10. The control host 4 starts the cylinder 3, whose telescopic shaft moves up along the slide 211, driving the ejector plate 30 and the side plate 31 to rise synchronously. The hollow guide rod 34 guides along the guide hole 221.

[0043] After the top plate 33 contacts the workpiece, it transmits the ejection reaction force to the pressure sensor 32. The sensor transmits the force signal to the control host 4 through the internal circuit. The host compares the force signal with the preset threshold and adjusts the pressure of the cylinder 3 to ensure that the ejection force is appropriate.

[0044] After the workpiece is ejected, the cylinder 3 retracts, and the ejector plate 30, side plate 31, etc. return to their initial positions, completing one cycle.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
