Description

Technical Field

[0001] This utility model relates to the field of stamping and flanging die technology, and in particular to a guide mechanism for a flanging assembly of an automotive parts die. Background Technology

[0002] The guiding mechanism of the flanging assembly for automotive parts molds is specifically designed for the flanging process requirements of automotive parts. It is used to precisely guide the relative movement of the punch and die in the flanging assembly during the flanging process, ensuring that the two maintain an accurate positional relationship during high-speed stamping, and meeting the stringent requirements of automotive parts for dimensional accuracy and appearance quality.

[0003] A search revealed Chinese patent publication number CN222551895U, which discloses a stamping and flanging die for automotive parts. The die includes a base, a mounting bracket, a worktable, and a demolding mechanism. The mounting bracket and base are fixedly connected, and the worktable is also fixedly connected to the base. The worktable has holes. The demolding mechanism includes a lower die, a drive assembly, a mounting plate, multiple springs, a connecting plate, and a push block. The drive assembly is fixedly connected to the worktable, and the mounting plate is fixedly connected to the drive assembly. The multiple springs connect the mounting plate and the connecting plate, and the push block is fixedly connected to the connecting plate. The drive assembly operates to drive... The component drives the mounting plate, spring, connecting plate, and push block to move vertically upwards. When it reaches a suitable height, the spring extends and drives the push block to move vertically upwards, pushing the parts stuck on the lower mold to complete the demolding of the parts. This solves the problem that the parts are easily stuck on the mold after the flanging is completed, making it inconvenient for operators to remove them and thus reducing work efficiency. However, in actual use, when the parts have asymmetrical surfaces, deep cavity structures, and abrupt changes in edge curvature, the mold frame guide surface cannot match the contour of the parts, resulting in uneven distribution of the contact area between the guide surface and the blank, and excessive local stress causing mold deformation. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a guiding mechanism for the flanging assembly of automotive parts molds, aiming to improve the problem in the prior art where the guide surface of the mold frame cannot match the contour of the part, resulting in uneven distribution of the contact area between the guide surface and the blank.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a guiding mechanism for a flanged assembly of an automotive parts mold, comprising a lower mold base, a lower mold slidably connected to the inner wall of the lower mold base, an upper mold slidably connected to the top of the lower mold, an upper mold base slidably connected to the top of the upper mold, a guide sliding mechanism provided at the top of the lower mold base, an ejection mechanism provided inside the lower mold, a wear-resistant mechanism provided on the right side of the guide sliding mechanism, a pre-pressing mechanism provided on the outer walls of both the lower mold and the upper mold, and an adjustment mechanism provided at the top of the lower mold for adjusting the position of the pressing point;

[0006] The guide mechanism includes two fixed seats. The bottoms of the two fixed seats are respectively fixedly connected to the front and rear sides of the top of the lower mold base. A pressure core is fixedly connected to the top of each of the two fixed seats. A guide surface is opened on the top of each of the two pressure cores. The inner walls of the two guide surfaces are slidably connected to the front and rear sides of the bottom of the upper mold. An L-shaped reinforcing block is fixedly connected to the right side of each of the two pressure cores. A triangular reinforcing block is fixedly connected to the opposite side of each of the two pressure cores. A reinforcing rib is fixedly connected to the inner wall of each of the two fixed seats.

[0007] Through the above technical solution: the fixed seats on the front and rear sides of the top of the lower mold base firmly support the pressure core. During the pressing of the upper mold, the front and rear sides of its bottom slide along the guide surface on the top of the pressure core to achieve precise guidance. The L-shaped reinforcing block and the triangular reinforcing block enhance the structural strength of the pressure core from the right side and the side away from it, respectively, so that it can withstand greater pressure. The reinforcing ribs on the inner wall of the fixed seat further reinforce the fixed seat, ensuring the stable operation of the guide sliding mechanism, ensuring that the upper mold moves smoothly during the mold flanging process, and improving the machining accuracy of the parts.

[0008] As a further description of the above technical solution:

[0009] The adjustment mechanism includes multiple mounting screws. The bottom outer walls of the multiple mounting screws are respectively threaded to the front and rear sides of the top of the lower mold. The middle part of the outer walls of the multiple mounting screws is slidably connected to corresponding connecting blocks. The tops of two connecting blocks are fixedly connected to guide blocks on opposite sides. The adjacent sides of the two guide blocks are provided with guide slopes. The tops of the two connecting blocks are provided with two slots. The inner walls of the multiple slots are fixedly connected to reinforcing blocks.

[0010] Through the above technical solution: when it is necessary to adjust the pressure point to adapt to different parts, loosen the mounting screw. Since the bottom of the mounting screw is threaded to the top of the lower mold, the constraint on the connecting block is reduced after loosening, which can push the connecting block and drive the guide block to move horizontally. The guide slope on the adjacent side of the guide block guides the part to better adapt to the mold when the part is placed and the mold is closed. The reinforcing block in the top slot of the connecting block enhances the structural strength of the connecting block, ensures the stability of the adjustment mechanism, and realizes flexible adjustment of the pressure point.

[0011] As a further description of the above technical solution:

[0012] The ejection mechanism includes multiple fixed rings, the outer walls of which are fixedly connected to the inner wall of the lower mold, the inner walls of which are fixedly connected to reset sleeves, the inner walls of which are slidably connected to ejector rods, and the tops of which are fixedly connected to ejector heads.

[0013] Through the above technical solution: the fixing ring on the inner wall of the lower mold firmly fixes the reset sleeve. After the part is formed, the external force causes the ejector rod to slide upward in the reset sleeve, which drives the top ejector head to push the part out of the lower mold. When the external force disappears, the reset sleeve uses its own characteristics to make the ejector rod fall back to reset, waiting for the next ejection operation.

[0014] As a further description of the above technical solution:

[0015] The wear-resistant mechanism includes multiple screws. The left side of the outer wall of each screw is threaded to the inner wall of the corresponding L-shaped reinforcing block. Wear-resistant plates are fixedly connected to the right side of the outer wall of each screw. The left side of each wear-resistant plate is in contact with the right side of the corresponding L-shaped reinforcing block. The right side of each wear-resistant plate is slidably connected to the front and rear sides of the bottom of the upper mold.

[0016] The above technical solution involves connecting the screws to the inner wall of the L-shaped reinforcing block with two threads, allowing the wear-resistant plate to be securely installed on its right side. During the up-and-down movement of the upper mold, the right side of the wear-resistant plate slides in contact with the front and rear sides of the bottom of the upper mold, effectively reducing frictional loss between the two, extending the service life of the L-shaped reinforcing block and the upper mold, and ensuring a smooth and stable sliding process.

[0017] As a further description of the above technical solution:

[0018] The pre-compression mechanism includes multiple connecting blocks 2, the inner sides of which are fixedly connected to the outer walls of the lower mold and the upper mold, respectively, and pre-compression pins are fixedly connected to the outer sides of each of the multiple connecting blocks 2.

[0019] Through the above technical solution: connecting block two is fixed on the outer wall of the lower and upper molds respectively, positioning the pre-pressing pin. Before the mold is closed, the pre-pressing pin first contacts the blank to apply pressure, so that the blank initially fits the mold, improving the stress and improving the forming quality of the parts.

[0020] As a further description of the above technical solution:

[0021] The bottom of the lower mold base is fixedly connected to a mounting plate, and two mounting slots are opened on the front and rear sides of the mounting plate. Mounting blocks are fixedly connected to the four corners of the top of the mounting plate.

[0022] The above technical solution provides overall support for the lower mold base through a bottom mounting plate. The mounting grooves on the front and rear sides of the mounting plate facilitate connection and fixation with external equipment using bolts. The mounting block at the top corner assists in precise positioning of the lower mold base, ensuring stable mold installation.

[0023] As a further description of the above technical solution:

[0024] Locking blocks 1 are fixedly connected to the front and rear sides of the lower mold. Locking blocks 2 are rotatably connected to the top of the two locking blocks 1. Screws 3 are threadedly connected to the inner walls of the two locking blocks 2. The adjacent ends of the outer walls of the two screws 3 are threadedly connected to the front and rear sides of the upper mold.

[0025] The above technical solution involves first fixing locking block one to the front and rear sides of the lower mold, then rotating locking block two around locking block one to a suitable angle to align with the corresponding position of the upper mold. Next, screw three is screwed into the inner wall of locking block two and threadedly connected to the front and rear sides of the upper mold, thereby firmly locking the upper and lower molds and ensuring stable mold closing.

[0026] As a further description of the above technical solution:

[0027] The lower mold has bases fixedly connected to the top of its front and rear sides, and each of the two bases has a positioning pin fixed to its top. The adjacent sides of the two positioning pins are slidably connected to the bottom of the front and rear sides of the upper mold, respectively.

[0028] Through the above technical solution: the positioning pins on the top base of the front and rear sides of the lower mold are slidably connected to the bottom of the front and rear sides of the upper mold. When the upper mold is pressed down, the positioning pins provide precise guidance, ensuring that the upper mold moves along a predetermined trajectory, ensuring accurate mold closing between the upper and lower molds, and improving the forming accuracy of the parts.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the fixed base is fixed on the top of the lower mold base, the guide surface of the pressure core is slidably connected to the bottom of the upper mold for precise guidance, the reinforcing block, the strengthening block and the reinforcing rib enhance the connection strength and prevent local deformation, the ejection mechanism can eject the formed parts, the wear-resistant mechanism reduces the wear of the upper mold, the pre-pressing mechanism allows the blank to fit better before mold closing and avoids local deformation due to force, the guide surface is moved to the pressure core and the resistance is enhanced, ensuring the efficient operation of the mold flanging assembly, reducing the design difficulty and improving the overall design efficiency and quality.

[0031] 2. In this utility model, when adjusting the pressure point to adapt to complex parts, the mounting screws are loosened. They are threadedly connected to the top of the lower mold. Loosening the screws reduces the constraint on the connecting block two, allowing the connecting block two to be pushed, which in turn moves the top guide block horizontally. The guide slope of the guide block guides the parts when they are placed and the mold is closed, helping the parts to adapt to the mold and optimizing the contact between the guide surface and the blank. The reinforcing block in the top slot of the connecting block two enhances its strength, ensuring the stability of the adjustment mechanism, allowing for flexible adjustment of the pressure point, preventing mold deformation, and improving the forming quality of the parts.

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.

[0041] Reference Figure 3 , Figure 4 and Figure 6This utility model provides an embodiment of a guide mechanism for a flanging assembly of an automotive parts mold, including a lower mold base 1, which provides an installation platform. A lower mold 5 is slidably connected to the inner wall of the lower mold base 1. The lower mold 5 is used to support and fix the automotive parts to be processed and is an important working area for mold flanging. An upper mold 6 is slidably connected to the top of the lower mold 5. When working, the upper mold 6 moves downward to cooperate with the lower mold 5 to perform flanging forming operations on the automotive parts. An upper mold base 7 is slidably connected to the top of the upper mold 6. The upper mold base 7 serves to connect and fix the upper mold 6 and provides guidance and power transmission interface for the movement of the upper mold 6. A guide sliding mechanism 2 is provided on the top of the lower mold base 1. The guide sliding mechanism 2 is used to guide the movement of the upper mold 6 and ensure its accuracy and stability during the up and down movement. An ejection mechanism 8 is provided inside the lower mold 5.

[0042] After the part is formed by flanging, the ejection mechanism 8 ejects the processed part from the lower mold 5, which facilitates the removal of the part and subsequent processing. The right side of the guide sliding mechanism 2 is provided with a wear-resistant mechanism 9, which can reduce the frictional wear between the guide sliding mechanism 2 and the upper mold 6 and extend the service life of the mechanism. The outer walls of both the lower mold 5 and the upper mold 6 are provided with a pre-pressing mechanism 10. The pre-pressing mechanism 10 applies a certain pressure to the blank before the mold is closed, so that the blank fits the mold better and improves the quality of flanging. The top of the lower mold 5 is provided with an adjustment mechanism 3, which is used to adjust the position of the pressure point to adapt to the processing needs of automotive parts of different shapes and sizes.

[0043] The guide mechanism 2 includes two fixed seats 201, which are used to fix the guide mechanism 2 to the lower mold base 1 to ensure its positional stability. The bottoms of the two fixed seats 201 are respectively fixedly connected to the front and rear sides of the top of the lower mold base 1 to achieve a stable connection with the lower mold base 1. A pressure core 202 is fixedly connected to the top of each of the two fixed seats 201. The pressure core 202 provides a guide surface for the movement of the upper mold 6 and also plays a certain role in pressing the blank. A guide surface 203 is opened on the top of each of the two pressure cores 202. The guide surface 203 is slidably connected to the front and rear sides of the bottom of the upper mold 6 to guide the up and down movement trajectory of the upper mold 6. An L-shaped reinforcing block 204 is fixedly connected to the right side of each of the two pressure cores 202. The L-shaped reinforcing block 204 strengthens the connection between the pressure core 202 and the fixed seat 1. The connection strength between the fixed seats 201 is improved, which enhances the overall stability of the guide sliding mechanism 2. The bottoms of the two L-shaped reinforcing blocks 204 are fixedly connected to the tops of the corresponding fixed seats 201 to ensure the stable installation of the L-shaped reinforcing blocks 204. Triangular reinforcing blocks 206 are fixedly connected to the opposite sides of the two pressure cores 202. The triangular reinforcing blocks 206 further enhance the structural strength between the pressure cores 202 and the fixed seats 201 to prevent deformation under stress. The bottoms of the two triangular reinforcing blocks 206 are fixedly connected to the tops of the corresponding fixed seats 201 to ensure the installation of the triangular reinforcing blocks 206 firmly. The inner walls of the two fixed seats 201 are fixedly connected to reinforcing ribs 205. The reinforcing ribs 205 enhance the structural strength of the fixed seats 201 so that they can better withstand pressure.

[0044] The ejection mechanism 8 includes multiple retaining rings 801, which are used to fix the reset sleeve 802 and keep it in a stable position inside the lower mold 5. The outer walls of the multiple retaining rings 801 are fixedly connected to the inner wall of the lower mold 5 to achieve a reliable connection with the lower mold 5. The inner walls of the multiple retaining rings 801 are fixedly connected to the reset sleeve 802, which provides a sliding track for the ejector rod 803 and also plays a reset role. The inner walls of the multiple reset sleeves 802 are slidably connected to the ejector rod 803, which slides up and down inside the reset sleeve 802 to eject the formed part. The top of the multiple ejector rods 803 is fixedly connected to the ejector head 804, which directly contacts the formed part and ejects it smoothly.

[0045] The wear-resistant mechanism 9 includes multiple screws 902, which are used to fix the wear-resistant plate 901 to the L-shaped reinforcing block 204, thus assembling the wear-resistant mechanism 9. The outer left side of the multiple screws 902 is threaded to the inner wall of the corresponding L-shaped reinforcing block 204, ensuring a firm connection between the screws 902 and the L-shaped reinforcing block 204. The outer right side of the multiple screws 902 is fixedly connected to the wear-resistant plate 901, which slides in contact with the bottom of the upper mold 6 to reduce friction. The left side of two wear-resistant plates 901 respectively fits against the right side of the corresponding L-shaped reinforcing block 204, ensuring the wear-resistant plate 901... The installation position of 01 is accurate. The right sides of the two wear-resistant plates 901 are slidably connected to the bottom front and rear sides of the upper mold 6, respectively, to reduce the wear of the upper mold 6 when sliding. The pre-pressing mechanism 10 includes multiple connecting blocks 1001. The connecting blocks 1001 are used to connect the lower mold 5 and the upper mold 6 with the pre-pressing pin 1002 to form the pre-pressing mechanism 10. The inner sides of the multiple connecting blocks 1001 are fixedly connected to the outer walls of the lower mold 5 and the upper mold 6, respectively, to achieve the connection with the mold. The outer sides of the multiple connecting blocks 1001 are all fixedly connected to the pre-pressing pin 1002. The pre-pressing pin 1002 applies pre-pressure to the blank before the mold is closed.

[0046] Specifically, two fixed seats 201 are fixed to the front and rear sides of the top of the lower mold base 1, respectively. The pressure core 202 at the top of the lower mold base 1 has a guide surface 203, which is slidably connected to the front and rear sides of the bottom of the upper mold 6. This design can provide precise guidance for the movement of the upper mold 6. At the same time, the L-shaped reinforcing block 204, the triangular reinforcing block 206, and the reinforcing rib 205 enhance the connection strength between the pressure core 202 and the fixed seat 201 from different directions, ensuring the stability of the guide mechanism 2 under pressure and avoiding deformation due to excessive local stress. The reset sleeve 802 in the ejection mechanism 8 is fixed to the inner wall of the lower mold 5 by the fixing ring 801. The ejector rod 803 can slide in the reset sleeve 802. The top ejector head 804 is used to eject the formed part at the appropriate time, making it convenient to remove the part. The wear-resistant mechanism 9 fixes the wear-resistant plate 901 to the right side of the L-shaped reinforcing block 204 by screw 2 902, which is connected to the upper mold base 6. The bottom sliding connection of the upper mold 6 effectively reduces wear during the sliding of the upper mold 6, extending the service life of the mold. The connecting block 1001 of the pre-pressing mechanism 10 is fixed to the outer wall of the lower mold 5 and the upper mold 6 respectively. The pre-pressing pin 1002 on the outside can apply a certain pressure to the blank before the mold is closed, so that the blank can better fit the mold in the initial stage, further improving the contact between the guide surface 203 and the blank, reducing uneven local stress, thereby effectively avoiding the deformation of the mold due to excessive local stress, ensuring the stable operation of the mold and the forming quality of the parts. By setting the pressure core 202 on the guide surface 203 and increasing the wall thickness and the number of ribs, the resistance of the guide surface 203 is effectively enhanced. This not only ensures that the system can work normally and stably under complex working conditions and ensures the efficient operation of the mold flanging component, but also greatly reduces the design difficulty, reduces obstacles and costs in the design process, and improves the overall design efficiency and quality.

[0047] Reference Figure 5 and Figure 6The adjusting mechanism 3 includes multiple mounting screws 303. These screws 303 connect the adjusting mechanism 3 to the lower mold 5 and adjust the position of the guide block 302. The bottom outer walls of the multiple mounting screws 303 are threaded to the front and rear top sides of the lower mold 5, providing a stable mounting base. The height can be adjusted by rotating the mounting screws 303. Corresponding connecting blocks 301 are slidably connected to the middle portions of the outer walls of the multiple mounting screws 303, allowing the connecting blocks 301 to move vertically as the mounting screws 303 are adjusted. The tops of two connecting blocks 301 are located on opposite sides. Each part is fixedly connected with a guide block 302, which is used to guide the position of the part in the mold. Each of the two guide blocks 302 has a guide slope 306 on an adjacent side. The guide slope 306 helps to guide the part to enter the appropriate position in the mold more accurately and optimize the fit between the part and the mold. Each of the two connecting blocks 301 has two slots 304 on the top. The slots 304 provide an installation position for the reinforcing blocks 305. The inner walls of the multiple slots 304 are fixedly connected with reinforcing blocks 305. The reinforcing blocks 305 enhance the structural strength of the connecting blocks 301 and make them less prone to deformation under pressure.

[0048] Specifically, when the position of the pressure point needs to be adjusted to accommodate complex parts of different shapes, first loosen the mounting screw 303. Since the bottom of the mounting screw 303 is threaded to the top of the lower mold 5, after loosening, the constraint of the mounting screw 303 on the connecting block 301, which is slidably connected to the middle of its outer wall, is reduced. At this time, the connecting block 301 can be pushed, thereby driving the guide block 302 fixed on the top of the connecting block 301 to move horizontally. The guide slope 306 opened on the adjacent side of the guide block 302 can guide the part during the placement of the part and the mold closing process, so that the part... The parts are better adapted to the mold, and the contact area between the guide surface 203 and the blank is optimized. At the same time, a reinforcing block 305 is fixed in the slot 304 opened at the top of the connecting block 301. The reinforcing block 305 enhances the structural strength of the connecting block 301, making it less prone to deformation when subjected to pressure from the parts and the mold during mold closing. This ensures the stable operation of the adjustment mechanism 3. Through this operation, the position of the pressure point can be flexibly adjusted, effectively improving the uneven local stress of the mold when processing complex parts, avoiding mold deformation due to excessive local stress, and improving the service life of the mold and the forming quality of the parts.

[0049] Reference Figure 1 , Figure 2 and Figure 6A mounting plate 4 is fixedly connected to the bottom of the lower mold base 1. The mounting plate 4 serves to fix the entire guide mechanism to the external equipment. Two mounting slots 14 are opened on the front and rear sides of the mounting plate 4. The mounting slots 14 facilitate the fastening connection of the mounting plate 4 to the external equipment by bolts. Mounting blocks 15 are fixedly connected to the four corners of the top of the mounting plate 4. The mounting blocks 15 provide positioning and auxiliary support for the installation of the lower mold 5. Locking blocks 11 are fixedly connected to the front and rear sides of the lower mold 5. Locking blocks 11 are used to cooperate with locking blocks 212 to lock the lower mold 5 to the upper mold 6. Locking blocks 212 are rotatably connected to the top of the two locking blocks 11. Locking blocks 212 can rotate around locking blocks 11 to facilitate the connection with the upper mold. 6. For connection and fixation, screws 13 are threadedly connected to the inner walls of the two locking blocks 12. Screws 13 are used to fasten the locking blocks 12 to the upper mold 6, ensuring a firm connection. The adjacent ends of the outer walls of the two screws 13 are threaded to the front and rear sides of the upper mold 6, further enhancing the stability of the connection between the lower mold 5 and the upper mold 6. The top of the front and rear sides of the lower mold 5 are fixedly connected to the base 16, which provides the mounting base for the positioning pins 17. The top of the two bases 16 are fixedly connected to the positioning pins 17, which are used to position and guide the movement of the upper mold 6. The adjacent sides of the two positioning pins 17 are slidably connected to the bottom of the front and rear sides of the upper mold 6, respectively, to ensure the positional accuracy of the upper mold 6 during the up and down movement.

[0050] Specifically, the mounting plate 4 at the bottom of the lower mold base 1, with its front and rear mounting grooves 14, can be securely fixed to external equipment using bolts, providing stable support for the entire mold. The mounting block 15 at the top corner of the mounting plate 4 assists in the precise positioning of the lower mold 5 and enhances its installation stability. The locking block 11 on the front and rear sides of the lower mold 5 and the locking block 2 12 rotatably connected to the top are tightly threaded to the front and rear sides of the upper mold 6 using screws 3 13, achieving a stable connection between the upper mold 6 and the lower mold 5. At the same time, the positioning pins 17 on the top base 16 on the front and rear sides of the lower mold 5 are slidably connected to the bottom of the front and rear sides of the upper mold 6, providing precise guidance for the movement of the upper mold 6, ensuring stable mold operation, and improving the machining accuracy of parts.

[0051] Working principle: When the device is running, two fixed seats 201 are fixed to the front and rear sides of the top of the lower mold base 1, respectively. The pressure core 202 at the top has a guide surface 203, which slides and connects with the front and rear sides of the bottom of the upper mold 6. This design can provide precise guidance for the movement of the upper mold 6. At the same time, the L-shaped reinforcing block 204, the triangular reinforcing block 206, and the reinforcing rib 205 enhance the connection strength between the pressure core 202 and the fixed seat 201 from different directions, ensuring the stability of the guide mechanism 2 under pressure and avoiding deformation due to excessive local stress. The reset sleeve 802 in the ejection mechanism 8 is fixed to the inner wall of the lower mold 5 by the fixing ring 801. The ejector rod 803 can slide in the reset sleeve 802. The top head 804 is used to eject the formed part at the appropriate time, making it easy to remove the part. The wear-resistant mechanism 9 fixes the wear-resistant plate 901 to the right side of the L-shaped reinforcing block 204 by screw 2 902. The upper mold 6 is slidably connected to the bottom of the upper mold 6, which effectively reduces the wear of the upper mold 6 during sliding and extends the service life of the mold. The connecting block 1001 of the pre-pressing mechanism 10 is fixed to the outer wall of the lower mold 5 and the upper mold 6 respectively. The pre-pressing pin 1002 on the outside can apply a certain pressure to the blank before the mold is closed, so that the blank can better fit the mold in the initial stage, further improve the contact between the guide surface 203 and the blank, reduce uneven local force, and thus effectively avoid the mold from deforming due to excessive local force, ensuring the stable operation of the mold and the forming quality of the parts. By setting the pressure core 202 on the guide surface 203 and increasing the wall thickness and the number of ribs, the resistance of the guide surface 203 is effectively enhanced. This not only ensures that the system can work normally and stably under complex working conditions and ensures the efficient operation of the mold flanging component, but also greatly reduces the design difficulty, reduces the obstacles and costs in the design process, and improves the overall design efficiency and quality.

[0052] Furthermore, when the position of the pressure point needs to be adjusted to accommodate complex parts of different shapes, first loosen the mounting screw 303. Since the bottom of the mounting screw 303 is threaded to the top of the lower mold 5, after loosening, the constraint of the mounting screw 303 on the connecting block 301, which is slidably connected to its outer wall, is reduced. At this time, the connecting block 301 can be pushed, thereby driving the guide block 302 fixed on the top of the connecting block 301 to move horizontally. The guide slope 306 opened on the adjacent side of the guide block 302 can guide the part during the placement of the part and the mold closing process, so that the part... The parts are better adapted to the mold, and the contact area between the guide surface 203 and the blank is optimized. At the same time, a reinforcing block 305 is fixed in the slot 304 opened at the top of the connecting block 301. The reinforcing block 305 enhances the structural strength of the connecting block 301, making it less prone to deformation when subjected to pressure from the parts and the mold during mold closing. This ensures the stable operation of the adjustment mechanism 3. Through this operation, the position of the pressure point can be flexibly adjusted, effectively improving the uneven local stress of the mold when processing complex parts, avoiding mold deformation due to excessive local stress, and improving the service life of the mold and the forming quality of the parts.
