[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] A sealing device for automotive mold stamping equipment includes a base 1, a sealing mechanism 2 welded to the top of the base 1, and rotating mechanisms 3 welded to both sides of the surface of the sealing mechanism 2. The sealing mechanism 2 includes a lower sealing shell 21, a front sealing shell 22, a rear sealing shell 23, a snap-fit ​​groove 24, and a sealing strip 25. The lower sealing shell 21 is welded to the top of the base 1, the front sealing shell 22 is rotatably connected to the front side of the top of the lower sealing shell 21, and the rear sealing shell 23 is rotatably connected to the rear side of the top of the lower sealing shell 21. The snap-fit ​​groove 24 is respectively opened on the inner side of the bottom of the front sealing shell 22 and the inner side of the bottom of the rear sealing shell 23. The sealing strip 25 is installed on the top of the lower sealing shell 21. A support beam 4 is welded to the top of the base 1, and an electric hydraulic jack 5 is installed at the bottom of the support beam 4. A lower pressure plate 6 is fixedly connected to the telescopic end of the bottom of the electric hydraulic jack 5.

[0028] In this embodiment: the base 1 supports and limits the sealing mechanism 2 and the support beam 4. The support beam 4 provides installation support for the electric hydraulic jack 5. The electric hydraulic jack 5 provides strong driving force to drive the lower pressure plate 6 to move up and down, performing a stamping operation on the workpiece inside the lower sealing shell 21. The lower pressure plate 6 stamps the workpiece under the drive of the electric hydraulic jack 5. The lower sealing shell 21 provides an installation base for the front sealing shell 22 and the rear sealing shell 23. At the same time, the sealing strip 25 on its top can cooperate with the snap-fit ​​groove 24 of the front and rear sealing shells 23 to enhance the tightness of the seal and prevent the outward diffusion of debris generated during stamping. The workpiece is supported and limited. The front sealing shell 22 and the rear sealing shell 23 open and close the sealing space by rotation, which facilitates the handling of the workpiece. During stamping, they close to form a closed space, blocking debris and dust from all directions and improving the sealing protection effect. The snap-fit ​​groove 24 cooperates with the sealing strip 25 on the top of the lower sealing shell 21, so that the front sealing shell 22 and the rear sealing shell 23 can be tightly snapped together with the lower sealing shell 21 when they are closed, reducing gaps and further enhancing the sealing performance and preventing leakage. When the sealing shell is closed, the sealing strip 25 is in close contact with the snap-fit ​​groove 24, filling the gaps and effectively blocking the passage of liquids, dust and debris, improving the sealing reliability of the sealing mechanism 2.

[0029] Specifically, such as Figure 3 As shown, the rotating mechanism 3 includes a limiting plate 31, a rotating rod 32, a support plate 33, a servo motor 34, a connecting block 35, and a PLC controller 36. The limiting plate 31 is welded to both sides of the front side of the lower sealing shell 21 and both sides of the rear side of the lower sealing shell 21.

[0030] Specifically, such as Figure 3 As shown, the rotating rod 32 is rotatably connected to the inner side of the limiting plate 31. The support plate 33 is welded to the front side of the top right side of the base 1 and the rear side of the top right side of the base 1, respectively. The servo motor 34 is installed on the right side of the support plate 33. The right side of the rotating rod 32 passes through the limiting plate 31 and is connected to the connecting shaft through a flat key.

[0031] Specifically, such as Figure 3 As shown, the output end of the servo motor 34 on the left side passes through the support plate 33 and is fixedly connected to the right side of the connecting shaft. The connecting block 35 is welded to both sides of the surface of the rotating rod 32. The side of the connecting block 35 away from the rotating rod 32 is welded to both sides of the bottom front side of the front sealing shell 22 and the bottom rear side of the rear sealing shell 23 respectively. The PLC controller 36 is installed on the surface of the left side of the support beam 4.

[0032] In this embodiment: the limiting plate 31 supports and limits the rotating rod 32, ensuring that the rotating rod 32 can only rotate stably within a limited range and preventing the rotating rod 32 from deviating. The rotating rod 32, through welding with the connecting block 35, transmits the power of the servo motor 34 to the front sealing shell 22 and the rear sealing shell 23, realizing the rotation and opening and closing of the sealing shell. The support plate 33 provides stable mounting support for the servo motor 34. The servo motor 34 drives the rotating rod 32 to rotate through the connection of the output end to the connecting shaft, thereby driving the front sealing shell 22 and the rear sealing shell 23 to open and close. The connecting block 35 connects the rotating rod 32 and the sealing shell, converting the rotation of the rotating rod 32 into the opening and closing action of the sealing shell. The PLC controller 36 is electrically connected to the angle sensor 8, the servo motor 34 and the pressure sensor 11, and can receive signals and control the operation of the servo motor 34.

[0033] Specifically, such as Figure 4 As shown, a limit ring 7 is welded to the left side of the rotating rod 32, and the surface of the limit ring 7 is coated with an anti-corrosion coating.

[0034] Specifically, such as Figure 4 As shown, an angle sensor 8 is installed on the right side of the surface of the rotating rod 32, and the angle sensor 8 is electrically connected to the PLC controller 36.

[0035] In this embodiment: by setting a limiting ring 7, the axial movement of the rotating rod 32 can be limited, preventing the rotating rod 32 from axially moving during rotation and ensuring the stable rotation of the rotating rod 32. By setting an anti-corrosion coating, its corrosion resistance is improved and its service life is extended. By setting an angle sensor 8, which is electrically connected to the PLC controller 36, the rotation angle of the rotating rod 32 can be detected in real time and the signal is transmitted to the PLC controller 36, so that the controller can grasp the opening and closing angle of the front sealing shell 22 and the rear sealing shell 23.

[0036] Specifically, such as Figure 4 As shown, an observation window 9 is provided on the inner side of the front side of the lower sealing shell 21, and high-temperature resistant tempered glass is installed on the inner side of the observation window 9.

[0037] Specifically, such as Figure 5As shown, a mounting hole 10 is provided on the inner side of the bottom of the lower pressure plate 6, and a pressure sensor 11 is installed on the inner side of the mounting hole 10.

[0038] In this embodiment: by setting the observation window 9, the operator can observe the stamping status of the internal workpiece in real time during the stamping process, which facilitates timely detection of abnormalities and improves the safety and convenience of operation. By setting the mounting hole 10, a mounting position is provided for the pressure sensor 11. By setting the pressure sensor 11, the pressure borne by the lower platen 6 during the stamping process can be detected in real time, and the pressure signal is transmitted to the PLC controller 36, which facilitates the controller to monitor and adjust the stamping process.

[0039] Working principle: First, the operator controls the servo motor 34 to start via the PLC controller 36. The output end of the servo motor 34 on the left side drives the connecting shaft to rotate. Since the connecting shaft is connected to the rotating rod 32 via a flat key, the rotating rod 32 rotates inside the limit plate 31. The connecting block 35 on the surface of the rotating rod 32 transmits the rotation to the front sealing shell 22 and the rear sealing shell 23, causing them to rotate upwards and open. At this time, the operator places the workpiece into the bottom of the lower sealing shell 21. Then, after the workpiece is placed, the operator controls the electric hydraulic jack 5 to start via the PLC controller 36. Its bottom telescopic end drives the lower pressure plate 6 to move downwards, pressing the workpiece inside the lower sealing shell 21. When the pressure sensor 11 contacts the workpiece, the PLC controller 36 controls the servo motor 34 to reverse, driving the rotating rod 32 to rotate in the opposite direction, and the front sealing shell 22... The rear sealing shell 23 rotates downwards to close. At this time, the sealing strip 25 at the top of the lower sealing shell 21 and the snap-fit ​​groove 24 on the inner side of the bottom of the front and rear sealing shells 23 are tightly engaged. The snap-fit ​​groove 24 makes the sealing shells tightly engaged to reduce gaps, and the sealing strip 25 fills the gaps to form a closed space. After that, during the stamping process, the pressure sensor 11 detects the pressure it bears in real time and transmits the signal to the PLC controller 36 to monitor the stamping pressure. At the same time, the operator can observe the stamping status of the internal workpiece in real time through the observation window 9. Finally, when the stamping is completed, the operator controls the servo motor 34 to start again through the PLC controller 36. The servo motor 34 drives the front sealing shell 22 and the rear sealing shell 23 to rotate upwards to open. At the same time, it controls the electric hydraulic jack 5 to drive the lower pressure plate 6 to reset upwards. At this time, the operator takes out the processed workpiece and completes the stamping operation.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
