[0010] As a preferred embodiment of this invention, the multiple micro sensors are interconnected and coordinated for control.

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

[0012] 1. By adopting a split-type die structure, it consists of three split-type groove molds: mold one, mold two, and mold three. This split design facilitates die manufacturing, reduces the processing difficulty and cost of large integral molds, and allows for individual replacement of damaged parts of the mold without replacing the entire mold, improving maintenance efficiency and reducing costs. Multiple interconnected and collaboratively controlled micro-sensors are embedded on the die surface to achieve real-time monitoring of the die's working status. This enables timely detection of abnormalities during the stamping process. Furthermore, it combines multiple positioning and fastening methods, including positioning arc key blocks and slots, positive and negative magnetic blocks, and connecting plates and pins. Positioning arc key blocks and slots provide initial positioning, positive and negative magnetic blocks enhance connection stability and assist in positioning, and connecting plates and pins further reinforce the die, forming a multi-layered, all-around positioning and fastening system. Compared to a single positioning method, this better ensures the accuracy and stability of the die during the stamping process, improving product quality and consistency.

[0013] 2. The sealing gasket not only serves a sealing function, but also connects to the magnetic holes on the mold through the connecting block and magnetic plug, achieving integrated sealing and fixing. This ensures that the sealing gasket maintains a good sealing state throughout the stamping process, avoiding the problem of easy displacement and detachment of the sealing parts in traditional sealing methods, and improving the reliability and service life of the mold.

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] Please see Figure 1-6This utility model provides a split-type concave die for stamping a car dashboard frame, including a split-type concave die 1, multiple micro sensors 6, a splicing panel 18, multiple positioning arc grooves 19, and multiple positioning arc key blocks 20. A split-type concave die 3 and a split-type concave die 2 are respectively provided on the front and right sides of the split-type concave die 1. Multiple micro sensors 6 are equidistantly embedded in the surfaces of the corresponding split-type concave die 1, split-type concave die 3, and split-type concave die 2. The split-type concave die 3 and... A connecting groove 4 is provided on the left side of the contact surface of the split groove mold 1. A connecting groove 5 is provided on the right side of the contact surface between the split groove mold 3 and the split groove mold 2. A sealing gasket 39 is provided in the connecting groove 4, and a sealing gasket 34 is provided in the connecting groove 5.

The positioning arc grooves 19 are equidistantly arranged on the rear side of the splicing panel 18. Multiple positioning arc key blocks 20 respectively engage with the corresponding positioning arc grooves 19. A groove connecting surface fixing plate 2 12 is fixedly connected to the left side of the split groove mold 3 and the contact surface of the split groove mold 1. A groove connecting surface fixing plate 8 is fixedly connected to the front recess of the split groove mold 1 and the contact surface of the split groove mold 3. A positioning groove 1 9 is provided on the right side of the groove connecting surface fixing plate 1 8. A positive positioning groove is installed on the left side of the groove connecting surface fixing plate 2 12. A magnetic block 13 is installed in a positioning groove 9. A negative magnetic block 10 is installed in the positioning groove 9. A groove connecting surface fixing plate 24 is fixedly connected to the right side of the split groove mold 3 and the contact surface of the split groove mold 2. A groove connecting surface fixing plate 4 25 is fixedly connected to the left side of the split groove mold 2 and the contact surface of the split groove mold 3.

A positioning groove 26 is provided on the left side of the groove connecting surface fixing plate 4 25. A negative magnetic block 28 is provided on the left side of the positioning groove 26.

[0023] The mold adopts a split-type concave mold structure, consisting of a split-type groove mold 1, a split-type groove mold 2, and a split-type groove mold 3. The split-type groove mold 3 and the split-type groove mold 1 are joined by a specific structure: on the contact surface of the two, a connecting groove 4 is provided on the left side of the split-type groove mold 3, with a built-in sealing gasket 39; the equidistantly distributed positioning arc key blocks 20 on the front side of the split-type groove mold 1 engage with the positioning arc grooves 19 on the rear splicing panel 18 of the split-type groove mold 3, achieving initial positioning. Simultaneously, the splicing of the split-type groove mold 3 and the split-type groove mold 2 is similar, with a connecting groove 5 on the right side of the split-type groove mold 3, and a built-in sealing gasket 34. This split-jointing design facilitates mold processing and manufacturing; when a part of the mold is damaged, the damaged split mold can be replaced individually, reducing maintenance costs and difficulty. At the splicing point between the split-type groove mold 1 and the split-type groove mold 3, a groove connecting surface fixing plate 8 and a groove connecting surface fixing plate 2 12 are respectively fixed to the contact surfaces of the two. A positioning groove 9 is provided on the right side of the groove connecting surface fixing plate 1 (8). A positive magnetic block 13 is installed on the left side of the groove connecting surface fixing plate 2 (12). A negative magnetic block 10 is installed in the positioning groove 9. Utilizing the mutual attraction between the positive and negative magnetic blocks, the two fixing plates are tightly fitted together. Similarly, at the joint between the split groove mold 3 (3) and the split groove mold 2 (2), the groove connecting surface fixing plate 3 (24) and the groove connecting surface fixing plate 4 (25) are fixed to the corresponding mold contact surfaces. A positive magnetic block 27 is installed on the right side of the groove connecting surface fixing plate 3 (24), and a positioning groove 26 is provided on the left side of the groove connecting surface fixing plate 4 (25). A negative magnetic block 28 is installed on the left side of the positioning groove 26. Positioning and reinforcement are achieved through the interaction of the magnetic blocks. Multiple micro-sensors 6 are equidistantly embedded on the surfaces of the split groove mold 1 (1), split groove mold 3 (3), and split groove mold 2 (2). During the stamping process of the automotive dashboard frame, these micro-sensors can monitor parameters such as pressure, temperature, and deformation on the mold surface in real time. Because multiple micro sensors are interconnected and work together for control, when a sensor detects abnormal data, such as sudden pressure changes, excessively high temperature, or local deformation of the mold exceeding the set range, it can promptly transmit a signal to the control system. The control system then adjusts the stamping parameters or stops the stamping operation, thereby avoiding mold damage and product quality defects. As a result, the automotive dashboard frame stamping die has a split die structure, which facilitates mold processing and manufacturing. When the mold is partially damaged, the damaged split die can be replaced separately, reducing maintenance costs and difficulty, and enhancing the connection strength and stability of the mold joints. It also plays an auxiliary positioning role, preventing relative displacement of the mold during the stamping process, and enables intelligent monitoring and control of the stamping process.

[0024] Multiple positioning arc key blocks 20 are fixedly connected to the top right side of each connecting disc 21. Each connecting disc 21 has a through hole 42 in its center, which is detachably connected to a matching fixing screw 22. Each fixing screw 22 is detachably connected to a corresponding fixing hole 23. The fixing holes 23 are equidistantly located on the top of the splicing panel 18, on the right side of multiple positioning arc grooves 19. Connecting discs are fixedly connected to the front sides of the groove connecting surface fixing plate one 8 and the groove connecting surface fixing plate two 12. Plate 11 and connecting plate 2 14 are provided with multiple fastening grooves 15 at equal intervals. Each fastening groove 15 has a detachable fixing pin 16. The front sides of the grooved connecting surface fixing plate 3 24 and the grooved connecting surface fixing plate 4 25 are respectively fixedly connected to the connecting plate 3 29 and the connecting plate 4 30. Each fastening groove 2 31 is provided with multiple fastening grooves 31 at equal intervals. Each fastening groove 2 31 has a detachable fixing pin 2 32.

[0025] Multiple positioning arc key blocks 20 are fixedly connected to the top right side of each connecting disc 21. The connecting disc 21 has a through hole 42 in the middle. The connecting disc 21 is detachably connected to the corresponding fixing hole 23 on the splicing panel 18 by passing through the through hole 42 with a matching fixing screw 22. When the split groove mold 1 and the split groove mold 3 are assembled, the positioning arc key block 20 first engages with the positioning arc groove 19 on the splicing panel 18 to achieve initial positioning. Then, the positioning arc key block 20 is further tightened to the splicing panel 18 by fixing screws 22 to prevent the positioning arc key block 20 from coming out of the positioning arc groove 19 during the stamping process. At the splicing point of the split groove mold 1 and the split groove mold 3, the front sides of the groove connecting surface fixing plate 18 and the groove connecting surface fixing plate 212 are respectively fixed to the connecting plate 11 and the connecting plate 214. Multiple fastening grooves 15 are equally spaced on the connecting plate 11 and the connecting plate 214. By inserting the matching fixing pin 16 into the fastening groove 15, the connecting plate 11 and the connecting plate 214 are secured together. The two 14 are connected together, which makes the connection between the groove connecting surface fixing plate 18 and the groove connecting surface fixing plate 22 more secure. This connection method further enhances the structural strength of the mold splice, which can withstand the large impact and shear force generated during the stamping process and prevent the mold from loosening or separating under force. Similarly, at the splice of the split groove mold 3 and the split groove mold 22, the connecting plate 329 and the connecting plate 430 on the front side of the groove connecting surface fixing plate 34 and the groove connecting surface fixing plate 425 are connected and fastened by inserting the fixing pin 232 into the fastening groove 231. This ensures the positioning accuracy and stability of the mold splice, thereby ensuring the dimensional accuracy of the stamped product and the stability and reliability of the overall mold structure.

[0026] A clamping pad 23 is provided between connecting plate 329 and connecting plate 430, and a clamping pad 17 is provided between connecting plate 11 and connecting plate 214;

[0027] A second shim 33 is installed between connecting plate three 29 and connecting plate four 30, and a first shim 17 is installed between connecting plate one 11 and connecting plate two 14. During the mold assembly process, when the connecting plates are connected by fixing pins, the shims will be compressed and deformed. The shims themselves have a certain degree of elasticity, which can play a buffering role, absorbing the vibration and impact force generated by the mold during the stamping process, reducing rigid collisions between various parts of the mold, thereby reducing mold wear and extending mold service life. At the same time, the shims fill the gaps between the connecting plates, which can further enhance the sealing of the mold joint, preventing lubricant, debris and other foreign objects from entering the mold joint gaps during the stamping process, avoiding problems such as mold wear, jamming or affecting the quality of stamped products due to foreign objects entering, and ensuring the normal operation of the mold and the quality of stamped products.

[0028] A magnetic suction hole 38 is provided at the top right rear end of the grooved connecting surface fixing plate 212, and a magnetic suction hole 37 is provided at the top left rear end of the grooved connecting surface fixing plate 324. A magnetic suction hole 43 is provided at the top of the position on the splicing panel 18 that contacts the sealing gasket 239 and the sealing gasket 134. A connecting block plate 20 is fixedly connected to the top left and right ends of the sealing gasket 239, and a connecting block plate 15 is fixedly connected to the top left and right ends of the sealing gasket 134. A magnetic suction rod 41 passes through the multiple connecting block plates 240, and a magnetic suction rod 36 passes through the multiple connecting block plates 135. The multiple magnetic suction rods 41 and 36 are respectively connected to the corresponding magnetic suction holes 237 and 33.

[0029] During mold assembly, sealing gasket 2 39 and sealing gasket 1 34 are positioned within connecting groove 1 4 and connecting groove 2 5, respectively. Magnetic insertion rod 1 41 on connecting plate 2 40 aligns with and inserts into corresponding magnetic holes 2 37 and 3 43, while magnetic insertion rod 2 36 on connecting plate 1 35 also inserts into corresponding magnetic hole 3 43. Utilizing magnetic attraction, the sealing gaskets are securely installed at the mold connection points, preventing displacement during stamping. Sealing gasket 2 39 and sealing gasket 1 34 respectively seal the connections between split groove mold 3 3 and split groove mold 1 1, and between split groove mold 3 3 and split groove mold 2 2, preventing material debris, oil, etc., from entering the connection gaps during stamping and affecting the mold's precision and service life. Meanwhile, the setting of magnetic suction hole 1 38, magnetic suction hole 2 37 and magnetic suction hole 3 43 provides accurate positioning and adsorption position for the magnetic suction rod, ensuring the installation accuracy and sealing effect of the sealing gasket. Through the cooperation of the magnetic suction rod and the magnetic suction hole, as well as the fixing of the sealing gasket by the connecting block plate, the sealing and stability of the mold connection part is achieved.

[0030] Multiple micro sensors 6 are covered with a cover strip 7 to protect the micro sensors 6. The cover strip 7 can prevent the micro sensors 6 from being interfered with or damaged by external factors, such as the impact of debris or the corrosion of oil stains that may be generated during the stamping process, and provide reliable data for mold monitoring and adjustment.

[0031] The tops and sides of multiple positive magnetic blocks 13 and 27 are covered with spring-loaded washers. During operation, at the connection points of the mold, positive magnetic blocks 13 and 10, and positive magnetic blocks 27 and 28, attract each other, tightly connecting the separate parts of the mold. The spring-loaded washers can buffer and dampen the mold when it is subjected to stamping impact, preventing positive magnetic blocks 13 and 27 from being damaged or weakened due to direct impact. They can also compensate for minor deformations that may occur in the mold during stamping, ensuring the stability and reliability of the magnetic connection.

[0032] Multiple micro-sensors 6 are interconnected and work together for coordinated control. By connecting these micro-sensors 6 into a network, they can work together to achieve comprehensive monitoring of the mold surface condition. Each micro-sensor 6 can monitor different locations or parameters on the mold surface. Through coordinated control, these scattered data can be integrated to more accurately reflect the overall state of the mold during the stamping process, such as the uniformity of pressure distribution and the trend of temperature changes. Once an anomaly occurs in a certain area, the system can quickly locate the problem based on the comprehensive data from multiple micro-sensors 6 and take corresponding measures in a timely manner, such as adjusting stamping parameters or stopping the stamping operation, to ensure the quality of the stamped products and the normal operation of the mold.

[0033] In this invention, the mold adopts a split-type concave mold structure, consisting of a split-type groove mold 1, a split-type groove mold 2, and a split-type groove mold 3. The split-type groove mold 3 and the split-type groove mold 1 are joined by a specific structure: on the contact surface of the two, a connecting groove 4 is provided on the left side of the split-type groove mold 3, with a built-in sealing gasket 39; the equidistantly distributed positioning arc key blocks 20 on the front side of the split-type groove mold 1 engage with the positioning arc grooves 19 on the rear splicing panel 18 of the split-type groove mold 3, achieving initial positioning. Simultaneously, the splicing of the split-type groove mold 3 and the split-type groove mold 2 is similar; a connecting groove 2 5 is provided on the right side of the split-type groove mold 3, with a built-in sealing gasket 34. This split-joint design facilitates mold processing and manufacturing; when a part of the mold is damaged, the damaged split mold can be replaced individually, reducing maintenance costs and difficulty. At the joint between the split groove mold 1 and the split groove mold 3, groove connecting surface fixing plate 8 and groove connecting surface fixing plate 2 are fixed to the contact surfaces of the two molds respectively. A positioning groove 9 is provided on the right side of groove connecting surface fixing plate 8, and a positive magnetic block 13 is installed on the left side of groove connecting surface fixing plate 2. A negative magnetic block 10 is installed inside the positioning groove 9. Utilizing the mutual attraction between the positive and negative magnetic blocks, the two fixing plates are tightly fitted together. Similarly, at the joint between the split groove mold 3 and the split groove mold 2, groove connecting surface fixing plate 3 24 and groove connecting surface fixing plate 4 25 are fixed to the corresponding mold contact surfaces respectively. A positive magnetic block 27 is installed on the right side of groove connecting surface fixing plate 3 24, and a positioning groove 26 is provided on the left side of groove connecting surface fixing plate 4 25. A negative magnetic block 28 is installed on the left side of positioning groove 26. Positioning and reinforcement are achieved through the interaction of the magnetic blocks. Multiple miniature sensors 6 are equidistantly embedded on the surfaces of the split groove mold 1, the split groove mold 3, and the split groove mold 2. During the stamping process of automotive dashboard frames, these micro-sensors can monitor parameters such as pressure, temperature, and deformation on the mold surface in real time. Because multiple micro-sensors are interconnected and work together for control, when a sensor detects abnormal data, such as sudden pressure changes, excessively high temperatures, or localized mold deformation exceeding the set range, it can promptly transmit a signal to the control system. The control system then adjusts the stamping parameters or stops the stamping operation, thereby preventing mold damage and product quality defects. This allows the automotive dashboard frame stamping mold to have a split-die structure, facilitating mold manufacturing.
