Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically a molding die for the front support leg of a car seat. Background Technology

[0002] Stamping of the front support legs of car seats is a common processing technology in automobile manufacturing. According to the performance requirements of the front support legs of car seats, steel with certain strength and toughness is usually selected, such as high-quality carbon structural steel and low-alloy high-strength steel.

[0003] During stamping, the die constantly contacts and rubs against the sheet metal, causing wear to critical parts such as the punch and die. Wear on the cutting edge leads to poor cross-sectional quality of the stamped part, resulting in increased burrs and larger corner collapses. Wear on the cavity surface affects the dimensional accuracy and surface quality of the stamped part. Furthermore, since dies are typically fixed with bolts after installation, replacement is inconvenient once wear occurs. During feeding, the sheet metal may jam or deviate, causing feeding difficulties. This affects the continuity and production efficiency of stamping, and may even lead to dimensional deviations in the stamped part. Therefore, this application provides a forming die for the front support leg of an automotive seat. Utility Model Content

[0013] As a further improvement of this utility model, a fitting groove is provided on the top of the body, which is adapted to the protrusion to keep the forming pressure block and the bearing pressure block in fit.

[0014] As a further improvement of this utility model, the bottom of the stamping assembly is provided with a support foot, the support foot including a support strip, and the support strip is adapted to the bottom of the stamping assembly by fixing bolts.

[0018] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0019] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0020] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 During the stamping process, key parts of the die, such as the punch and die, are prone to wear due to continuous contact and friction with the sheet metal. Wear on the cutting edge will deteriorate the cross-sectional quality of the stamped part, resulting in increased burrs and larger corner collapses; wear on the cavity surface will affect the dimensional accuracy and surface quality of the stamped part.

[0021] Mold installation is usually fixed with bolts. Once wear occurs, it is not convenient to replace later. Furthermore, the sheet metal may jam or deviate during feeding, resulting in uneven feeding, affecting stamping continuity and production efficiency, and may also cause dimensional deviations in stamped parts. Based on this, this application provides a forming mold for the front support leg of an automobile seat, including a stamping assembly 1 for forming. The stamping assembly 1 has a forming pressure block 4 and a bearing pressure block 5 on its inner side for stamping the target object. The stamping assembly 1 includes an upper die 11 and a lower die 13. The bottom of the upper die 11 is adapted to the forming pressure block 4, and the lower die 13 is adapted to the bearing pressure block 5. Telescopic components 12 are provided at the diagonal corners of the four sides of the upper mold 11 and the lower mold 13 to move the upper mold 11 and the lower mold 13 closer together; The top of the forming block 4 is provided with a connecting component 3 for fitting with the upper mold 11. The telescopic component 12 drives the upper mold 11 to reciprocate, and works with the connecting component 3 to press the target object. The top of the lower mold 13 is adapted to the bearing pressure block 5. The bearing pressure block 5 includes a block 51, an inner cavity 55 is provided on the inner side of the block 51, and a forming lower mold 56 is provided on the inner side of the inner cavity 55. It cooperates with the forming upper mold 44 installed on the forming pressure block 4 and performs stamping under the action of the telescopic member 12. The lower mold 56 includes a mold cavity 562, a cross-shaped retaining block 561 is provided at the bottom of the mold cavity 562, and a fixing block 563 is provided on the inner side of the mold cavity 562. The upper forming die 44 and the fixed block 563 are symmetrically and oppositely arranged to stamp the target object.

[0022] The stamping assembly 1 of this forming die mainly consists of an upper die 11 and a lower die 13. The upper die 11 and the lower die 13 realize the stamping forming of the front support leg of the car seat, and the two cooperate with each other to complete the stamping action.

[0023] Telescopic components 12 are installed at the diagonal corners of the four sides of the upper mold 11 and the lower mold 13. The telescopic components 12 can be hydraulic telescopic rods or electric push rods, etc., which can realize telescopic functions. Taking hydraulic telescopic rods as an example, hydraulic telescopic rods are powered by hydraulic systems and can accurately control their telescopic length and speed.

[0024] When a stamping operation is required, the hydraulic system controls the extension rod to extend, causing the upper die 11 to move downwards and approach the lower die 13; after stamping is completed, the extension rod retracts, causing the upper die 11 to return to its initial position. This extension rod 12 enables the upper die 11 to reciprocate, providing power and a motion basis for stamping.

[0025] The forming block 4 is located inside the stamping assembly 1, and a connecting assembly 3 is provided on its top. The connecting assembly 3 can be a snap-fit ​​structure, for example, a slot is provided on the top of the forming block 4, and a snap block that matches the slot is provided on the bottom of the upper mold 11.

[0026] During installation, align the locking block at the bottom of the upper mold 11 with the locking groove at the top of the forming block 4 and press gently to complete the connection. This connection method not only facilitates the installation of the forming block 4 and the upper mold 11, but also allows for easy disassembly when the forming block 4 needs to be replaced due to wear. When the telescopic component 12 drives the upper mold 11 to reciprocate, the upper mold 11 drives the forming block 4 to move together through the connecting component 3, pressing the target object (i.e., the raw material sheet of the front support leg of the car seat) placed on the bearing block 5.

[0027] The top of the lower mold 13 is adapted to the bearing pressure block 5. The bearing pressure block 5 includes a block 51, and an inner cavity 55 is provided on the inner side of the block 51. The function of the inner cavity 55 is to provide installation space and protection for the lower mold 56. The lower mold 56 is installed inside the inner cavity 55 and includes a mold cavity 562. A cross-shaped retaining block 561 is provided at the bottom of the mold cavity 562.

[0028] The function of the cross-shaped retaining block 561 is to securely fix the lower forming die 56 to the bottom of the inner cavity 55. A cross-shaped retaining groove 58 adapted to the cross-shaped retaining block 561 can be provided at the bottom of the inner cavity 55. When installing the lower forming die 56, the cross-shaped retaining block 561 is aligned with the cross-shaped retaining groove 58 and inserted to achieve initial fixation of the lower forming die 56. A fixing block 563 is provided on the inner side of the die cavity 562. The fixing block 563 is used to limit and support the target object during the stamping process.

[0029] The upper forming mold 44 is mounted on the forming pressure block 4 and is arranged symmetrically and oppositely to the fixing block 563 of the lower forming mold 56. When the telescopic component 12 drives the upper mold 11 to move downward, the upper forming mold 44 on the forming block 4 moves downward accordingly, cooperating with the lower forming mold 56 to stamp the target object. During the stamping process, the target object is placed in the mold cavity 562 of the lower forming mold 56, and the fixing block 563 limits the target object to prevent it from moving during the stamping process. The upper forming mold 44 applies downward pressure, working together with the lower forming mold 56 to gradually shape the target object into the shape of the front support leg of a car seat.

[0030] Because the molding block 4 and the lower molding die 56 adopt a structure that is easy to install and disassemble, these parts can be easily replaced when they are worn, avoiding the situation where the entire mold becomes unusable due to wear of key parts of the mold, thus extending the overall service life of the mold.

[0031] Please see Figure 3 , Figure 4 , Figure 5 as well as Figure 6 The connecting component 3 includes a fixed cavity 31 and a pressure spring 32 disposed inside the fixed cavity 31. The fixed cavity 31 is disposed at the bottom of the upper mold 11 and extends to the inside of the upper mold 11.

[0032] An auxiliary shaft 15 is provided between the upper mold 11 and the lower mold 13, located between the two telescopic members 12, to assist in supporting the upper mold 11 and the lower mold 13.

[0033] Positioning holes 16 are provided at the diagonal corners of the top four sides of the upper mold 11. The positioning holes 16 are adapted to the piston rod end of the telescopic member 12. A fixing member 14 is provided on the outside of the telescopic member 12 to fix the fixing member 14 and keep the telescopic member 12 fixed.

[0034] The inner cavity 55 of the block 51 is provided with a clamping area 57, which is adapted to the lower forming mold 56 and is used to fix the lower forming mold 56. One or more limiting members 54 arranged in a linear array are provided on both sides of the inner wall of the clamping area 57 to restrict the outer walls of the lower forming mold 56.

[0035] A protrusion 53 is provided in the middle of the block 51. The protrusion 53 is adapted to the forming pressure block 4 to maintain the stability of the two during stamping. A combination hole 52 is provided at the top four sides of the block 51. The combination hole 52 is adapted to the top of the lower mold 13 to fix the block 51.

[0036] A cross-shaped slot 58 is provided on the bottom inner side of the clamping area 57, which is adapted to the cross-shaped slot 561 of the forming lower mold 56.

[0037] The connecting assembly 3 consists of a fixed cavity 31 and a pressure spring 32 located inside the fixed cavity 31. The fixed cavity 31 is located at the bottom of the upper mold 11 and extends inward therein. When the forming block 4 needs to be installed, the forming block 4 is aligned with the fixed cavity 31. During the installation process, the pressure spring 32 is compressed and contracts, generating an elastic force. On the one hand, the elastic force can make the forming block 4 tightly connected to the upper mold 11, ensuring that the forming block 4 will not loosen during the stamping process. On the other hand, when the forming block 4 needs to be replaced later, the elasticity of the pressure spring 32 helps to remove the forming block 4 more easily. When disassembling, only a portion of the elastic force of the pressure spring 32 needs to be overcome to remove the forming block 4 from the fixed cavity 31, realizing a convenient replacement operation, thereby solving the problem of inconvenient replacement after mold parts wear.

[0038] An auxiliary shaft 15 is positioned between the upper die 11 and the lower die 13, between the two telescopic members 12. The auxiliary shaft 15 assists in supporting the upper die 11 and the lower die 13. During the stamping process, the telescopic members 12 drive the upper die 11 in a reciprocating motion, generating a significant impact force. The auxiliary shaft 15 can absorb some of this impact force, ensuring the stability of the upper die 11 and the lower die 13 during movement. For example, when the telescopic members 12 drive the upper die 11 to press downwards, the auxiliary shaft 15 prevents the upper die 11 from tilting or wobbling, ensuring accurate alignment between the forming block 4 and the supporting block 5. This improves the stamping precision and quality, and reduces problems such as dimensional deviations in stamped parts caused by die instability.

[0039] Positioning holes 16 are provided at the diagonal corners of the top four sides of the upper mold 11. These positioning holes 16 are adapted to the piston rod end of the telescopic component 12. When installing the telescopic component 12, the piston rod end of the telescopic component 12 is accurately inserted into the positioning holes 16, ensuring accurate connection between the telescopic component 12 and the upper mold 11. A fixing member 14 is provided on the outer side of the telescopic component 12 to secure it and maintain stability. For example, the fixing member 14 can be a fixing structure composed of bolts and nuts. By tightening the bolts and nuts, the telescopic component 12 is firmly fixed in the appropriate position. This fixing method ensures that the telescopic component 12 will not shift or shake during operation, thereby stably driving the upper mold 11 to reciprocate and achieve accurate stamping of the target object.

[0040] The inner cavity 55 of the block 51 is provided with a clamping area 57, which is adapted to the forming die 56. When the forming die 56 is installed, it is placed into the clamping area 57 to achieve initial positioning of the forming die 56. One or more limiting members 54 arranged in a linear array are provided on both sides of the inner wall of the clamping area 57. The limiting members 54 can be small protrusions or elastic blocks, etc. These limiting members 54 restrict the outer walls of the forming die 56 to prevent the forming die 56 from swaying or displacing during the stamping process. For example, when the forming die 56 is subjected to stamping pressure, the limiting members 54 can tightly abut against the outer wall of the forming die 56 to keep it stable, ensure the smooth progress of the stamping process, and improve the quality of the stamped parts.

[0041] A protrusion 53 is provided in the middle of the block 51, which is adapted to the forming pressure block 4. During the stamping process, when the forming pressure block 4 moves downward and contacts the block 51, the protrusion 53 can fit tightly with the forming pressure block 4 to maintain the stability of both during stamping. For example, the protrusion 53 can play a positioning and guiding role, so that the forming pressure block 4 is accurately aligned with the forming lower die 56, avoiding deviations during the stamping process. Combination holes 52 are provided on all four sides of the top edge of the block 51, which are adapted to the top of the lower die 13. When installing the block 51, bolts or other connecting parts are used to connect it to the corresponding position on the top of the lower die 13 through the combination holes 52, thus fixing the block 51. This fixing method ensures that the block 51 and the lower die 13 are tightly integrated, jointly bearing the pressure during the stamping process and ensuring the overall stability of the die.

[0042] A cross-shaped groove 58 is provided on the inner bottom of the clamping area 57, which is adapted to the cross-shaped locking block 561 on the bottom of the forming lower die 56. When installing the forming lower die 56, the cross-shaped locking block 561 is accurately inserted into the cross-shaped groove 58 to achieve precise positioning and firm fixation of the forming lower die 56. The cooperation between the cross-shaped groove 58 and the cross-shaped locking block 561 not only prevents the forming lower die 56 from moving in the horizontal direction, but also withstands vertical pressure to a certain extent, ensuring the stability of the forming lower die 56 during the stamping process and further improving the forming quality of the stamped parts.

[0043] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 The forming block 4 includes a body 42. The bottom of the body 42 is adapted to the forming upper mold 44. A matching groove 41 is provided in the middle of the bottom of the body 42. The matching groove 41 is adapted to the protrusion 53 on the bearing block 5.

[0044] The top of the body 42 is provided with a fitting groove 41, which is adapted to the protrusion 43 to keep the molding block 4 and the bearing block 5 in a fitting position.

[0045] The bottom of the stamping assembly 1 is provided with a support foot 2, which includes a support bar 21. The support bar 21 is adapted to the bottom of the stamping assembly 1 by a fixing bolt 22.

[0046] The forming block 4 includes a body 42, the bottom of which is fitted with the upper forming die 44. This means that in actual stamping operations, the upper forming die 44 can be accurately installed on the bottom of the body 42. For example, the upper forming die 44 can be fixed to the bottom of the body 42 by bolt connection or snap-fit. When the telescopic member 12 drives the upper die 11 to move downward, the body 42 together with the upper forming die 44 applies downward pressure to stamp the target object (the raw material sheet of the front support leg of the car seat) placed on the lower forming die 56. This close fit ensures that the upper forming die 44 can function stably during the stamping process, allowing the target object to be formed according to the predetermined shape.

[0047] A fitting groove 41 is provided at the bottom center of the body 42, which is adapted to the protrusion 53 on the bearing pressure block 5. Before the stamping process begins, when the forming pressure block 4 is moved downwards and close to the bearing pressure block 5, the protrusion 53 will accurately embed into the fitting groove 41, playing a role in positioning and guiding.

[0048] On the one hand, it ensures that the forming block 4 and the bearing block 5 are accurately aligned in the horizontal direction, so that the upper forming die 44 can be accurately aligned with the lower forming die 56, avoiding deviations during the stamping process, thereby improving the dimensional accuracy of the stamped parts; On the other hand, during the stamping process, the cooperation between the protrusion 53 and the mating groove 41 can enhance the stability between the forming block 4 and the bearing block 5, reduce the shaking caused by the stamping impact force, and ensure the smooth progress of the stamping process.

[0049] The top of the body 42 is provided with a mating groove 41, which is adapted to the protrusion 43 to keep the forming block 4 and the supporting block 5 in a proper fit. The protrusion 43 can be positioned at a specific location on the upper mold 11. When the telescopic member 12 moves the upper mold 11 downwards, bringing the forming block 4 closer to the supporting block 5, the protrusion 43 will embed into the mating groove 41 at the top of the body 42, further enhancing the stability of the forming block 4 during the stamping process. It not only positions and stabilizes from the bottom (through the protrusion 53 and the bottom mating groove 41) but also constrains from the top (through the protrusion 43 and the top mating groove 41), ensuring that the forming block 4 maintains an accurate fit with the supporting block 5 throughout its up-and-down movement, thus improving the stamping accuracy and quality.

[0050] The bottom of the stamping assembly 1 is provided with a support foot 2, which includes a support strip 21. The support strip 21 is adapted to the bottom of the stamping assembly 1 by fixing bolts 22. When installing the support foot 2, the support strip 21 is placed in a suitable position on the bottom of the stamping assembly 1. Then, the fixing bolts 22 are passed through the mounting holes on the support strip 21 and the corresponding threaded holes on the bottom of the stamping assembly 1. By tightening the fixing bolts 22, the support strip 21 is firmly fixed to the bottom of the stamping assembly 1.

[0051] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
