Description

Technical Field

[0001] This application relates to the field of automotive parts manufacturing and processing technology, and in particular to a seat slide rail mold. Background Technology

[0002] Seat rails are used to adjust the position of car seats inside the vehicle to meet the seating needs of different people. Existing seat rails need to be formed by stamping and other processing methods. When stamping the rails, the metal raw material sheet is placed on the forming groove of the lower die, and then the upper die descends to drive the bending block to squeeze the sheet, finally obtaining the bent rail.

[0003] However, the forming groove width in existing stamping dies is usually a fixed value. If the thickness of the raw material sheet is greater than the design tolerance of the forming groove, the forming gap is too small, which can easily cause stress concentration due to excessive extrusion, leading to cracks or surface wrinkles at the bending point of the slide rail. When the raw material sheet is smaller than the forming groove width, the forming gap is too large, and the material is prone to shift during the stamping process, causing deviation in the bending angle of the slide rail.

[0004] Therefore, any thickness deviation in the metal raw materials will lead to a reduction in the forming quality of the slide rail, resulting in significant deficiencies. Utility Model Content

[0005] To improve the molding quality of the slide rail, this application provides a seat slide rail mold.

[0006] The seat slide rail mold provided in this application adopts the following technical solution:

[0007] A seat slide rail mold includes an upper mold and a lower mold arranged opposite to each other. The upper mold is provided with a bending block for bending. The lower mold is provided with a forming component. The forming component includes a first forming block and a second forming block slidably connected to the lower mold. A forming groove is formed between the opposing surfaces of the first forming block and the second forming block. The upper mold is provided with an adjustment component, which pushes the first forming block to move toward or away from the second forming block.

[0008] By adopting the above technical solution, when there is a deviation in the thickness of the raw material, the first forming block is moved towards or away from the second forming block by adjusting the component. This allows the width of the forming groove to be adjusted according to the thickness of the raw material, ensuring that the material is always in the optimal plastic deformation range during the bending process. This effectively eliminates the reduction in the forming quality of the slide rail caused by the deviation in the thickness of the sheet metal, thereby improving the forming quality of the slide rail.

[0009] Optionally, the upper mold is provided with a mounting shell, and the lower mold is provided with a mounting groove that slides with the mounting shell. The adjustment component includes a push plate and an adjustment pad disposed in the mounting shell. The push plate and the adjustment pad are both wedge-shaped and their inclined surfaces are in contact with each other. The push plate and the adjustment pad are slidably connected inside the mounting shell along the length and width directions, respectively. The adjustment pad is provided with an adjustment block for pushing the first molding block. The upper mold is provided with a manual operation component, which drives the push plate to move along the length direction of the mounting shell. When the upper mold and the lower mold are closed, the adjustment block is in contact with the end face of the first molding block.

[0010] By adopting the above technical solution, when the thickness of the sheet is thin, the user can manually operate the component to drive the push plate to move backward. The push plate, in cooperation with the inclined surface of the adjustment pad, pushes the adjustment pad to move towards the first forming block. The adjustment pad drives the adjustment block to push the first forming block towards the second forming block, thereby reducing the width of the forming groove to accommodate the thinner workpiece.

[0011] Optionally, the manual operation component includes a guide seat disposed on the mounting housing, an adjusting screw rotatably connected within the guide seat, and the end of the adjusting screw being threadedly connected to the push plate.

[0012] By adopting the above technical solution, during adjustment, the user can rotate the adjusting screw in the forward or reverse direction. Under the limit of the mounting shell, the rotation of the adjusting screw drives the push plate to slide along the length direction of the mounting shell. The inclined contact surface between the push plate and the adjusting pad generates sliding friction. The forward or backward movement of the push plate is converted into the lateral displacement of the adjusting pad along the width direction of the mounting shell through the inclined surface cooperation. The adjusting pad drives the adjusting block to move synchronously, thereby realizing the adjustment of the width of the forming groove.

[0013] Optionally, a connecting plate is provided on the surface of the first molding block away from the upper mold. Multiple adjusting pins are slidably passed through the connecting plate. The adjusting assembly also includes a clamping spring sleeved on the outer surface of the adjusting pins. A mounting seat is provided on the lower mold that is threadedly connected to the end of the adjusting pin. The end face of the mounting shell facing the first molding block is provided on the abutment block. One end of the clamping spring abuts against the mounting seat, and the other end abuts against the end face of the connecting plate. The elastic force of the clamping spring pushes the connecting plate toward the abutment block. When not adjusted, there is an adjustment gap between the opposite end faces of the connecting plate and the abutment block.

[0014] By adopting the above technical solution, when the thickness of the sheet is relatively large, the user can manually operate the component to drive the push plate forward. At this time, a gap is generated between the inclined surface of the push plate and the adjusting pad, the force of the push plate on the adjusting pad disappears, and the clamping spring pushes the connecting plate towards the abutting block under its own elastic force until it abuts against the abutting block. The movement of the connecting plate drives the first forming block to move away from the second forming block, thereby increasing the width of the forming groove to accommodate the thicker workpiece.

[0015] Optionally, a limit cap is provided at the end of the adjusting pin near the connecting plate, and a limit groove is provided on the connecting plate to slide with the limit cap. When not adjusted, there is a gap between the end faces of the limit cap and the limit groove.

[0016] By adopting the above technical solution, when the upper mold and the lower mold are separated, the adjusting block is disengaged from the first forming block, the resistance force on the clamping spring disappears, and the clamping spring pushes the connecting plate to slide on the adjusting shaft until the limit cap abuts against the end face of the limit groove, thereby effectively preventing the connecting plate from moving forward and disengaging from the adjusting shaft, and ensuring that the subsequent adjustment of the forming groove width is always within the preset safety threshold.

[0017] Optionally, the mounting housing has multiple placement slots along its length, and each placement slot is provided with a connecting pin. The end of the connecting pin passes through the push plate and is threaded to the adjusting pad. The push plate has a waist-shaped hole that slides with the connecting pin. The adjusting assembly also includes a return spring sleeved on the outer surface of the connecting pin. One end of the return spring abuts against the inner sidewall of the placement slot, and the other end is disposed on the connecting pin.

[0018] By adopting the above technical solution, after the adjustment is completed, the user can manually operate the component to drive the push plate to reset. The pressure on the reset spring gradually decreases. Since the connecting pin is threaded on the adjustment plate, the reset spring resets and drives the connecting pin to pull the adjustment pad to reset, thereby restoring the forming groove width to the preset state and avoiding the accumulation of the next stamping gap deviation caused by manual reset error.

[0019] Optionally, the upper mold has a retaining block on its surface facing the lower mold. When the upper mold and the lower mold are closed, the retaining block abuts against the end face of the second forming block that is away from the first forming block.

[0020] By adopting the above technical solution, the contact pressure between the clamping block and the second forming block during mold closing can offset the lateral extrusion force of the bending block on the forming groove during the stamping process, preventing the second forming block from undergoing slight displacement or vibration due to unilateral force, and further ensuring the dimensional stability of the forming groove during the bending stage.

[0021] Optionally, the adjusting block is detachably mounted on the adjusting pad by multiple connecting bolts, and the abutting block is detachably mounted on the mounting shell by multiple connecting bolts.

[0022] By adopting the above technical solution, the setting of connecting bolts realizes the detachable connection between the adjusting block and the adjusting pad, and the detachable connection between the abutment block and the mounting shell. This makes it convenient for workers to replace the adjusting block and the abutment block in a timely manner after they are worn or damaged, thereby ensuring the stable operation of the adjustment work.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. In this embodiment of the application, by setting an adjustment component, the width of the forming groove is adjusted according to the thickness of the raw material, ensuring that the material is always in the optimal plastic deformation range during the bending process, effectively eliminating the reduction in the forming quality of the slide rail caused by the thickness deviation of the sheet metal, thereby improving the forming quality of the slide rail.

[0025] 2. In this embodiment of the application, a manual operation component is provided. During adjustment, the user rotates the adjusting screw in the forward or reverse direction. Under the limit of the mounting shell, the rotation of the adjusting screw drives the push plate to slide along the length direction of the mounting shell. The inclined contact surface between the push plate and the adjusting pad generates sliding friction. The forward or backward movement of the push plate is converted into the lateral displacement of the adjusting pad along the width direction of the mounting shell through the inclined surface cooperation. The adjusting pad drives the adjusting block to move synchronously, thereby realizing the adjustment of the width of the molding groove. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0035] This application discloses a seat slide rail mold.

[0036] Reference Figure 1 and Figure 2 A seat slide rail mold includes an upper mold 1 and a lower mold 2 arranged opposite to each other. A bending block 101 for bending is installed on the surface of the upper mold 1 facing the lower mold 2. A forming component 3 is provided inside the lower mold 2. The forming component 3 includes a first forming block 31 and a second forming block 32 slidably connected inside the lower mold 2. A forming groove 33 is provided between the opposing surfaces of the first forming block 31 and the second forming block 32 for accommodating the bent part of the workpiece. An elastic support part (not shown in the figure) is installed inside the lower mold 2. The elastic support part is provided inside the forming groove 33 for supporting the workpiece. A pressing block 102 is fixedly connected to the surface of the upper mold 1 facing the lower mold 2. When the upper mold 1 and the lower mold 2 are closed, the pressing block 102 presses against the end face of the second forming block 32 away from the first forming block 31.

[0037] During stamping, the raw material sheet is first placed on the lower die 2. During stamping, the upper die 1 descends, causing the bending block 101 to move downward. The bending block 101 exerts downward pressure on the workpiece and the elastic support is formed to create a bend. During the bending process, the contact pressure between the pressing block 102 and the second forming block 32 offsets the lateral extrusion force of the bending block 101 on the forming groove 33 during the stamping process, preventing the second forming block 32 from undergoing slight displacement or vibration due to unilateral force, and ensuring the dimensional stability of the forming groove 33 during the bending stage.

[0038] Reference Figure 1 and Figure 3 The upper mold 1 is equipped with an installation shell 4, and the lower mold 2 has an installation groove 21 that slides with the installation shell 4. The installation groove 21 is located on the side of the first molding block 31 away from the second molding block 32. When the mold is closed, the installation shell 4 slides into the installation groove 21.

[0039] Reference Figure 3 , Figure 4 and Figure 5 An adjustment assembly 5 is provided inside the mounting shell 4. The adjustment assembly 5 includes a push plate 51 and an adjustment pad 52 that are slidably connected inside the mounting shell 4. Both the push plate 51 and the adjustment pad 52 are wedge-shaped and their inclined surfaces are in contact with each other. The push plate 51 is inclined from front to back along the direction close to the first molding block 31. The push plate 51 and the adjustment pad 52 are slidably connected inside the mounting shell 4 along the length and width directions, respectively. An adjustment block 53 for pushing the first molding block 31 is detachably connected to the adjustment pad 52 by a connecting bolt (not shown in the figure). When the adjustment block 53 is worn, the user should replace the adjustment block 53 in time to ensure the accuracy of the adjustment. When the upper mold 1 and the lower mold 2 are closed, the adjustment block 53 is in contact with the end face of the first molding block 31 that is away from the second molding block 32.

[0040] Reference Figure 3 , Figure 4 and Figure 5 The mounting housing 4 has multiple placement slots 41 along its length. Each placement slot 41 is provided with a connecting pin 6. The end of the connecting pin 6 passes through the push plate 51 and is threaded onto the adjusting pad 52. The push plate 51 has a waist-shaped hole 511 that slides with the connecting pin 6. The adjusting assembly 5 also includes a return spring 54 sleeved on the outer surface of the connecting pin 6. One end of the return spring 54 abuts against the inner wall of the placement slot 41, and the other end is fixedly connected to the connecting pin 6. The return spring 54 is used to return the adjusting pad 52 to its initial state.

[0041] Reference Figure 3 , Figure 4 and Figure 5 The upper mold 1 is equipped with a manual operation component 7, which includes a guide seat 71 on one end face of the mounting shell 4. An adjusting screw 72 is rotatably connected inside the guide seat 71. The end of the adjusting screw 72 is threadedly connected to the push plate 51. During adjustment, the user rotates the adjusting screw 72 in the forward or reverse direction. Under the limit of the mounting shell 4, the adjusting screw 72 rotates and drives the push plate 51 to slide along the length direction of the mounting shell 4. The inclined contact surface of the push plate 51 and the adjusting pad 52 generates sliding friction. The forward or backward movement of the push plate 51 is converted into the lateral displacement of the adjusting pad 52 along the width direction of the mounting shell 4 through the inclined surface cooperation. The adjusting pad 52 drives the adjusting block 53 to move synchronously.

[0042] Reference Figure 5 , Figure 6 and Figure 7A connecting plate 311 is installed on the surface of the first forming block 31 facing away from the upper mold 1. In this embodiment, there are multiple connecting plates 311, which are evenly distributed along the length of the first forming block 31. Multiple adjusting pins 8 are slidably passed through each connecting plate 311. The adjusting assembly 5 also includes a clamping spring 55 sleeved on the outer surface of the adjusting pin 8. A mounting seat 81 threadedly connected to the end of the adjusting pin 8 is installed on the lower mold 2. An abutting block 42 is detachably connected to the end face of the mounting shell 4 facing the first forming block 31 by a connecting bolt. One end of the clamping spring 55 abuts against the mounting seat 81, and the other end abuts against the end face of the connecting plate 311. The elastic force of the clamping spring 55 pushes the connecting plate 311 toward the abutting block 42. When not adjusted, there is an adjustment gap 9 between the opposite end faces of the connecting plate 311 and the abutting block 42.

[0043] After the mold is closed, the adjusting block 53 moves to fit the end face of the first forming block 31. When the thickness of the sheet is thin, the user drives the push plate 51 to move backward through the manual operation component 7. The push plate 51 pushes the adjusting plate 52 to move towards the first forming block 31 by cooperating with the inclined surface of the adjusting plate 52. Since the connecting pin 6 is threadedly connected to the adjusting plate 52, the movement of the adjusting plate 52 pulls the connecting pin 6 to move laterally. The return spring 54 deforms in the placement groove 41. At the same time, the adjusting plate 52 drives the adjusting block 53 to push the first forming block 31 towards the second forming block 32. The movement of the first forming block 31 causes the width of the forming groove 33 to become smaller to accommodate the thinner workpiece.

[0044] When the plate is thick, the user manually operates component 7 to drive the push plate 51 forward. At this time, a gap is generated between the push plate 51 and the inclined surface of the adjusting pad 52. The force of the push plate 51 on the adjusting pad 52 disappears, and the resistance force of the clamping spring 55 from the adjusting block 53 disappears. Under its own elastic force, the clamping spring 55 pushes the connecting plate 311 toward the abutting block 42 until it abuts against the abutting block 42. The movement of the connecting plate 311 causes the first forming block 31 to move away from the second forming block 32, thereby increasing the width of the forming groove 33 to accommodate thicker workpieces.

[0045] After adjustment, the user manually operates component 7 to reset push plate 51. The pressure on reset spring 54 gradually decreases. Since connecting pin 6 is threaded onto adjustment plate, reset spring 54 resets and drives connecting pin 6 to pull adjustment pad 52 to reset, thereby restoring the width of forming groove 33 to the preset state and avoiding the accumulation of gap deviation in the next stamping caused by manual reset error.

[0046] Reference Figure 7Each adjusting pin 8 has an integrally formed limit cap 82 at its end near the connecting plate 311. The connecting plate 311 has a limit groove 10 that slides with the limit cap 82. When not adjusted, there is a gap of the same length as the adjusting gap 9 between the opposite end faces of the limit cap 82 and the limit groove 10. When the upper mold 1 separates from the lower mold 2, the adjusting block 53 disengages from the first forming block 31, the resistance force on the clamping spring 55 disappears, and the clamping spring 55 pushes the connecting plate 311 to slide on the adjusting shaft until the limit cap 82 abuts against the end face of the limit groove 10, thereby effectively preventing the connecting plate 311 from moving forward and disengaging from the adjusting shaft, ensuring that the width adjustment of the subsequent forming groove 33 is always within the preset safety threshold.

[0047] The implementation principle of a seat slide rail mold in this application embodiment is as follows: After the mold is closed, the adjusting block 53 moves to fit the end face of the first forming block 31. When the thickness of the plate is thin, the user drives the push plate 51 to move backward through the manual operation component 7. The push plate 51 pushes the adjusting pad 52 to move towards the first forming block 31 by cooperating with the inclined surface of the adjusting pad 52. Since the connecting pin 6 is threadedly connected to the adjusting pad 52, the movement of the adjusting pad 52 pulls the connecting pin 6 to move laterally. The return spring 54 deforms in the placement groove 41. At the same time, the adjusting pad 52 drives the adjusting block 53 to push the first forming block 31 towards the second forming block 32. The movement of the first forming block 31 causes the width of the forming groove 33 to become smaller to adapt to the thinner workpiece.

[0048] When the plate is thick, the user manually operates component 7 to drive the push plate 51 forward. At this time, a gap is generated between the push plate 51 and the inclined surface of the adjusting pad 52. The force of the push plate 51 on the adjusting pad 52 disappears, and the resistance force of the clamping spring 55 from the adjusting block 53 disappears. Under its own elastic force, the clamping spring 55 pushes the connecting plate 311 toward the abutting block 42 until it abuts against the abutting block 42. The movement of the connecting plate 311 causes the first forming block 31 to move away from the second forming block 32, thereby increasing the width of the forming groove 33 to accommodate thicker workpieces.

[0049] The adjustment component 5 allows the width of the forming groove 33 to be adjusted according to the thickness of the raw material, ensuring that the material is always in the optimal plastic deformation range during the bending process. This effectively eliminates the reduction in the forming quality of the slide rail caused by the thickness deviation of the sheet metal, thereby improving the forming quality of the slide rail.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
