Description

Technical Field

[0002] In the field of automotive part manufacturing, production molds, as a commonly used shaping tool, are widely used in the processing and production of various automotive parts to facilitate users in shaping raw materials into the desired part shapes. During the mold closing process, the upper and lower molds directly contact and collide, easily generating a large impact force. This not only causes wear to the molds themselves, reducing the service life of the molds, but also may affect the accuracy of the produced automotive parts, resulting in quality problems such as dimensional deviations. However, traditional devices cannot adjust the buffering force, resulting in an uncontrollable buffering effect when dealing with the production of various types of automotive parts. At the same time, traditional automotive part production molds cannot clean the inside of the mold during the production process, causing debris, impurities, etc. generated during the production process to easily remain in the mold, affecting the forming quality of subsequent parts and reducing the product yield rate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Through the arrangement of the electromagnetic coil, pressure sensor and magnetorheological fluid in the buffer assembly, the user can adjust the buffer effect according to the buffer force required during the production of different automotive parts, significantly improving the adaptability of the device in various automotive part production scenarios. After the pressure sensor senses the pressure change during the die closing process, the user can change the rheological characteristics of the magnetorheological fluid by controlling the current magnitude of the electromagnetic coil, causing the viscosity of the magnetorheological fluid to change, and then adjusting the buffer force provided by the buffer column to meet different production requirements, improving the device's ability to ensure die life and product accuracy. For example, when producing small automotive parts with high precision requirements, the buffer force can be made softer by finely adjusting the current of the electromagnetic coil to avoid the impact force affecting the part accuracy; while when producing large and relatively simple-structured parts, the current can be increased to provide a stronger buffer force to protect the die.

[0017] 2. When using the device, the user can connect an external high-pressure gas source through the air pipe connector in the cleaning assembly, enabling a plurality of high-pressure nozzles to spray high-pressure gas to clean the inside of the die, improving the device's self-cleaning ability during the production process. Then, through the setting of the filtering device, the device can filter the gas entering the high-pressure nozzles to prevent impurities in the gas from being ejected by the high-pressure nozzles and causing damage such as scratches to the die surface and the parts being formed, bringing a higher-quality production environment for the user and improving the device's ability to produce automotive parts with a high yield rate. For example, during continuous production, debris and impurities can be promptly cleaned by the high-pressure nozzles as soon as they are generated, and at the same time, the filtering device ensures the purity of the cleaning gas, ensuring that the subsequent produced parts are not affected by impurities, thereby increasing the product yield rate. The ceramic layers on the surfaces of the punch and insert of the device improve the hardness, wear resistance and corrosion resistance of the device, extend the service life of the parts, and reduce the die maintenance cost.

[0038] Two sets of slide seat groups 18 are symmetrically arranged at both ends of the punch 16 and the insert 17 respectively. By the symmetric arrangement of the slide seat groups 18, the forces on the punch 16 and the insert 17 can be ensured to be uniform, so that the device can avoid the offset of the punch 16 or the insert 17 caused by uneven force, which affects the production accuracy, and improves the ability of the device to maintain the production accuracy.

[0040] The fixing member includes a fixing rod 34 and a top rod 35. The top rod 35 is arranged on the fixing rod 34. By the cooperation of the fixing rod 34 and the top rod 35, the tightening and loosening of the punch 16 or the insert 17 can be realized by adjusting the position of the top rod 35 on the fixing rod 34, so that the device can control the fixing force. A limiting groove 36 is clamped on the top rod 35, and a limiting block 37 is provided on the fixing rod 34. The limiting block 37 is slidably connected to the limiting groove 36. By the setting of the limiting groove 36 and the limiting block 37, the movement range of the top rod 35 can be limited, and the precision of the fixing adjustment of the device is improved.

[0041] At the top of the fixed rod 34, there are a sleeve 38 and an end cap 31. The sleeve 38 is connected to the fixed rod 34 through the end cap 31. Through the setting of the end cap 31, the sleeve 38 can be installed at the top of the fixed rod 34, enabling the device to ensure the position stability of the sleeve 38 on the fixed rod 34 and improving the reliability of the structural connection of the device.

[0045] The cleaning assembly further includes an air pipe connector 45 and a filtering device 46. The air pipe connector 45 is arranged on the upper mold 11 and the lower mold 12. By providing the air pipe connector 45, it is convenient to connect to an external high-pressure air source, enabling the device to provide a stable air source supply for the high-pressure air nozzles 22, and improving the air supply stability of the cleaning system of the device. Multiple groups of high-pressure air nozzles 22 are connected to the external high-pressure air source through the air pipe connector 45. By connecting the high-pressure air nozzles 22 to the air pipe connector 45, the high-pressure gas can be guided to the parts of the mold that need to be cleaned, enabling the device to clean the inside of the mold. The filtering device 46 is installed on the air pipe connector 45. By providing the filtering device 46, the impurities in the gas entering the high-pressure air nozzles 22 can be filtered, enabling the device to prevent impurities from damaging the mold and the product, and improving the protection ability of the device for the mold and the product during the cleaning process.

[0046] As Figure 1 , 10 shown, multiple groups of positioning holes 19 are formed on the punch 16, and multiple groups of positioning posts 21 are arranged on the insert 17. The multiple groups of positioning posts 21 correspond to the multiple groups of positioning holes 19 in position. By providing the positioning holes 19 and the positioning posts 21, positioning can be provided when the punch 16 and the insert 17 are clamped. Ceramic layers are provided on the surfaces of the punch 16 and the insert 17. By providing the ceramic layers, the hardness, wear resistance, and corrosion resistance of the surfaces of the punch 16 and the insert 17 can be improved, enabling the device to extend the service life of the punch 16 and the insert 17.

[0047] The specific usage mode and function of this embodiment:

[0048] When the mold starts to be clamped, the upper mold 11 moves downward, and the buffer posts 13 on the lower mold 12 gradually approach and contact the contact posts 15 on the upper mold 11. Since the buffer posts 13 are arranged in the buffer chambers 23 evenly distributed circumferentially along the clamping surface of the lower mold 12, and the buffer chambers 23 are filled with magnetorheological fluid, the buffer posts 13 slide in the magnetorheological fluid to start providing preliminary buffering. Here, the sealing ring 24 prevents the leakage of the magnetorheological fluid to ensure the stable operation of the buffer system; the guide ring 25 ensures the straightness and stability of the sliding of the buffer posts 13. The return spring 47 can provide the elastic force for returning. The electromagnetic coil 27 is wound around the outer periphery of the buffer chamber 23 and is electrically connected to the pressure sensor 28 located on the upper mold 11. During the clamping process, the pressure sensor 28 monitors the pressure received by the mold and feeds the signal back to the electromagnetic coil 27. The electromagnetic coil 27 adjusts the magnetic field strength according to the pressure change, changes the rheological characteristics of the magnetorheological fluid, and further adjusts the buffering force. For example, when producing different types of automotive parts, different buffering force requirements exist, and this system can automatically adjust according to the actual pressure to ensure that the mold and the parts are not affected by excessive impact forces, protecting the mold and improving the product precision.

[0049] When it is necessary to replace the punch 16 or the insert 17, the fixing part can be operated to achieve quick disassembly. The sleeve 38 at the top of the fixing rod 34 of the fixing part is rotatable. By rotating the sleeve 38, the ejector rod 35 threadedly connected to the sleeve 38 slides in the limiting groove 36 of the fixing rod 34. The limiting block 37 on the ejector rod 35 cooperates with the limiting groove 36 to ensure the stable movement of the ejector rod 35. When the ejector rod 35 moves, it pushes the latch 41 in the guiding groove 39, so that the latch 41 disengages from the clamping groove 33 of the punch 16 or the insert 17, thereby loosening the punch 16 or the insert 17. During installation, operate in the reverse direction. Align the sliders 29 at both ends of the punch 16 or the insert 17 with the slide seat group 18. The slide seat group 18 is symmetrically distributed at both ends of the punch 16 and the insert 17, providing a stable sliding track for them. After the installation is in place, rotate the sleeve 38 to make the latch 41 snap into the clamping groove 33 to quickly complete the fixation. This improves the die repair efficiency and reduces the production downtime.

[0050] The air pipe connection seat 45 is connected to an external high-pressure air source to provide a stable high-pressure air flow for multiple groups of high-pressure air nozzles 22. During the production process, the high-pressure air nozzles 22 spray high-pressure gas into the die to timely clean up the generated debris and impurities. The filtering device 46 is installed on the air pipe connection seat 45 to filter the gas entering the high-pressure air nozzles 22, preventing impurities from being ejected with the air flow to scratch the die surface or affect the forming quality of the components, ensuring the cleanliness inside the die and improving the product qualification rate.

[0051] The anti-falling parts on both sides of the punch 16 are composed of a fixing ring 42 and a fixing column 43. The fixing ring 42 is sleeved on the fixing columns 43 located on the upper die 11 and the punch 16 respectively and is fixed by nuts. During the installation and working process of the punch 16, the anti-falling parts prevent the punch 16 from accidentally falling, ensuring the safety of the operators and avoiding damage to the punch 16 and the die due to falling. The ceramic layers on the surfaces of the punch 16 and the insert 17 improve their hardness, wear resistance and corrosion resistance, extend the service life of the components and reduce the die maintenance cost.

[0052] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
