Description

Technical Field

[0001] This utility model relates to the field of automotive seat slide rail processing technology, and in particular to an automotive seat slide rail stamping equipment that is easy to change molds. Background Technology

[0002] Car seat rails are important mechanical components of seats. Common rails are mainly installed under the seat and are used to adjust the seat's forward, backward, left, and right positions. The manufacturing process of car seat rails involves stamping.

[0003] A search revealed a Chinese patent (CN218963742U) for a stamping device used for stamping automotive seat slide rails. The device includes a support box, a lower die fixedly mounted on the top of the support box, a forming chamber on the lower die, and an ejection mechanism within the forming chamber. Two vertical plates are mounted on the top of the support box, and a control box is fixedly mounted between the two vertical plates. Two hydraulic cylinders are fixedly mounted on the bottom inner wall of the control box. A common drive plate is fixedly mounted on the output shafts of the two hydraulic cylinders. An upper punch is mounted on the bottom of the drive plate, and the upper punch is adapted to the lower die. The ejection mechanism includes a groove, a top plate, and a push rod.

[0004] However, the stamping device mentioned above for stamping automotive seat slide rails has its shortcomings. It is inconvenient to easily and efficiently disassemble and replace the upper punch and lower die according to different specifications of automotive seat slide rails. This means that one device can only stamp one specification of automotive seat slide rail, reducing the device's application range. When another specification of automotive seat slide rail needs to be processed, the entire device needs to be replaced, which increases the processing and production cost. Therefore, we propose an automotive seat slide rail stamping equipment that is easy to change dies to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a stamping equipment for automotive seat slide rails that facilitates mold changing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An easy-to-change stamping equipment for automotive seat slide rails includes a base, a lower die, and an upper die for stamping automotive seat slide rails. Two mounting plates are fixedly connected to the top of the base. A convenient disassembly and assembly mechanism is provided between the lower die and the two mounting plates. A gantry frame is fixedly connected to the top of the base. A hydraulic cylinder is fixedly connected to the top of the gantry frame. A hollow plate is fixedly connected to the output shaft of the hydraulic cylinder. A die-changing mechanism is provided between the hollow plate and the upper die. An ejection and demolding mechanism is provided between the base and the lower die.

[0008] As a preferred embodiment of this utility model, the ejection and demolding mechanism includes an electric push rod fixedly connected to the bottom of the base, a lifting plate fixedly connected to the output shaft of the electric push rod, two push rods fixedly connected to the top of the lifting plate, and two through holes opened at the bottom of the lower mold, with the two push rods slidably sleeved in the corresponding through holes.

[0009] As a preferred embodiment of this utility model, two guide rods are fixedly connected to the upper and lower inner walls of the base, and the lifting plate is slidably sleeved on the outside of the two guide rods.

[0010] In a preferred embodiment of this utility model, the mold changing mechanism includes a rotating shaft rotatably connected to the top of the hollow plate and a bidirectional screw rotatably connected to the inner walls of both sides of the hollow plate. A driving bevel gear is fixedly connected to the bottom end of the rotating shaft, and a driven bevel gear is fixedly sleeved on the outer side of the bidirectional screw. The driving bevel gear and the driven bevel gear mesh with each other. Two movable plates are threaded on the outer side of the bidirectional screw. Two horizontal plates are fixedly connected to the sides of the two movable plates that are far apart from each other. A vertical plate is fixedly connected to one side of the two horizontal plates. A fixing block is fixedly connected to one side of the vertical plate. Fixing grooves are opened on both sides of the upper mold, and the two fixing blocks are respectively movably engaged in the corresponding fixing grooves.

[0011] As a preferred embodiment of this invention, the top end of the rotating shaft extends above the hollow plate and is fixedly connected to a handwheel.

[0012] As a preferred embodiment of this utility model, the top of the mounting plate has two guide grooves, the mounting plate has a cavity, the convenient disassembly and assembly mechanism includes four guide blocks, four return springs fixedly connected to the inner wall of one side of the cavity, one end of the four return springs is fixedly connected to a movable plate, the inner side of the movable plate is fixedly connected to four locking blocks, the four guide blocks are respectively fixedly connected to both sides of the lower mold, one side of the guide block has a locking groove, eight locking blocks are respectively movably locked into the corresponding locking groove, the outer side of the movable plate is fixedly connected to two pull rods, and the four guide blocks are respectively slidably sleeved in the corresponding guide grooves.

[0013] In a preferred embodiment of this utility model, one end of two pull rods located on the same side is fixedly connected to the same hand handle, one side of the mounting plate is rotatably connected to a rotating shaft, one side of the mounting plate is fixedly connected to a torsion spring, one end of the rotating shaft and the torsion spring is fixedly connected to the same baffle, and the baffle movably abuts against the outside of the hand handle.

[0014] As a preferred embodiment of this invention, the top of the gantry frame is slidably provided with two limiting rods, both of which are fixedly connected to the top of the hollow plate.

[0015] In this utility model, an automotive seat slide rail stamping device that facilitates mold changing is described. When different specifications of slide rails need to be stamped, the handwheel rotates the shaft and the active bevel gear. The active bevel gear drives the driven bevel gear and the double-headed screw to rotate. The double-headed screw drives the two moving plates, four horizontal plates, two vertical plates, and two fixed blocks to move away from each other, causing the fixed blocks to disengage from the fixed groove and not fix the upper mold. The upper mold is removed, and then the upper mold of the corresponding specification is placed at the bottom of the hollow plate. The shaft is rotated in the opposite direction, so that the two vertical plates and the two fixed blocks move closer to each other. The upper mold can be clamped and fixed by the two vertical plates, and the two fixed blocks are snapped into the fixed groove, thereby achieving the effect of snapping and fixing, making the fixation of the upper mold more secure.

[0016] In this utility model, an automotive seat slide rail stamping device that facilitates mold changing is described. The baffle is pushed upwards, preventing it from limiting the handrail. Pulling the two handrails outwards causes four pull rods and two movable plates to move outwards. The movable plates cause the locking blocks to move outwards, disengaging from the locking slots and no longer fixing the guide blocks and lower mold. The lower mold and four guide blocks can then be disassembled. The lower mold corresponding to the upper mold and the four guide blocks are then placed into the guide groove. Releasing the handrail causes the two movable plates and eight locking blocks to move inwards under the force of the return spring and engage with their corresponding slots, thus fixing the guide blocks and lower mold. Finally, releasing the baffle causes the rotating shaft and baffle to deflect downwards and reposition under the torque of the torsion spring, abutting against the outside of the handrail. This prevents the handrail and locking blocks from sliding outwards and thus securely fixing the lower mold, improving the stability of the lower mold installation.

[0017] This utility model has a reasonable structural design. The mold changing mechanism facilitates the installation and disassembly of the upper mold, making it easy to replace. The convenient disassembly and assembly mechanism facilitates the convenient and efficient disassembly and assembly of the lower mold, allowing for the replacement of lower molds of different specifications. By replacing the upper and lower molds of different specifications, it is possible to stamp different specifications of car seat slides, improving the practicality and reliability of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4 A stamping equipment for automotive seat slide rails that facilitates mold changing includes a base 1, a lower mold 3, and an upper mold 7 for stamping automotive seat slide rails. Two mounting plates 10 are fixedly connected to the top of the base 1. A convenient disassembly and assembly mechanism 9 is provided between the lower mold 3 and the two mounting plates 10. A gantry frame 2 is fixedly connected to the top of the base 1. A hydraulic cylinder 4 is fixedly connected to the top of the gantry frame 2. A hollow plate 6 is fixedly connected to the output shaft of the hydraulic cylinder 4. A mold changing mechanism 8 is provided between the hollow plate 6 and the upper mold 7. An ejection and demolding mechanism 5 is provided between the base 1 and the lower mold 3.

[0025] Furthermore, refer to Figure 2 The ejection and demolding mechanism 5 includes an electric push rod 51 fixedly connected to the bottom of the base 1. A lifting plate 52 is fixedly connected to the output shaft of the electric push rod 51. Two ejector rods 54 are fixedly connected to the top of the lifting plate 52. Two through holes 55 are opened at the bottom of the lower mold 3. The two ejector rods 54 are slidably sleeved in the corresponding through holes 55.

[0026] Using the above solution: Activate the electric push rod 51, which drives the lifting plate 52 and the two push rods 54 to move upward, thereby pushing the formed slide rail out of the lower mold 3, which facilitates the demolding operation of the slide rail after forming. Through the cooperation of the push rod 54 and the through hole 55, the lower mold 3 can be installed and positioned to avoid displacement during installation.

[0027] Furthermore, two guide rods 53 are fixedly connected to the upper and lower inner walls of the base 1, and the lifting plate 52 is slidably sleeved on the outside of the two guide rods 53, which facilitates the guiding and limiting of the lifting plate 52, making its movement more stable.

[0028] Furthermore, refer to Figure 1 and Figure 4 The mold changing mechanism 8 includes a rotating shaft 82 rotatably connected to the top of the hollow plate 6 and a bidirectional screw 86 rotatably connected to the inner walls on both sides of the hollow plate 6. A driving bevel gear 83 is fixedly connected to the bottom end of the rotating shaft 82. A driven bevel gear 85 is fixedly sleeved on the outer side of the bidirectional screw 86. The driving bevel gear 83 and the driven bevel gear 85 mesh with each other. Two movable plates 80 are threaded on the outer side of the bidirectional screw 86. Two horizontal plates 89 are fixedly connected to the side of the two movable plates 80 that are far apart from each other. A vertical plate 88 is fixedly connected to one side of the two horizontal plates 89. A fixing block 87 is fixedly connected to one side of the vertical plate 88. Fixing grooves 84 are opened on both sides of the upper mold 7. The two fixing blocks 87 are movably engaged in the corresponding fixing grooves 84.

[0029] The above scheme is adopted: rotating the shaft 82 and the driving bevel gear 83, the driving bevel gear 83 drives the driven bevel gear 85 and the double-direction screw 86 to rotate, the double-direction screw 86 drives the two moving plates 80, four horizontal plates 89, two vertical plates 88 and two fixing blocks 87 to move away from each other, and makes the fixing blocks 87 disengage from the fixing groove 84 without fixing the upper mold 7. The upper mold 7 is removed, and then the upper mold 7 of the corresponding specification is placed at the bottom of the hollow plate 6. Rotating the shaft 82 in the opposite direction makes the two vertical plates 88 and the two fixing blocks 87 move closer to each other. The upper mold 7 can be clamped and fixed by the two vertical plates 88, and the two fixing blocks 87 are engaged in the fixing groove 84, thereby achieving the effect of engagement and fixation, making the fixation of the upper mold 7 more secure.

[0030] Furthermore, the top of the rotating shaft 82 extends above the hollow plate 6 and is fixedly connected to a handwheel 81, which facilitates the rotation of the rotating shaft 82.

[0031] Furthermore, refer to Figures 1-3The mounting plate 10 has two guide grooves 902 on its top and a cavity 901 inside. The easy disassembly and assembly mechanism 9 includes four guide blocks 903 and four return springs 907 fixedly connected to the inner wall of one side of the cavity 901. One end of each return spring 907 is fixedly connected to a movable plate 906. Four locking blocks 905 are fixedly connected to the inner side of the movable plate 906. The four guide blocks 903 are fixedly connected to both sides of the lower mold 3. A locking groove 904 is provided on one side of each guide block 903. The eight locking blocks 905 are used to move and lock the lower mold 3. The movable plate 906 is fixedly connected to two pull rods 908 in the corresponding slot 904. Four guide blocks 903 are slidably sleeved in the corresponding guide grooves 902. One end of the two pull rods 908 on the same side is fixedly connected to the same hand handle 909. One side of the mounting plate 10 is rotatably connected to a rotating shaft 910. One side of the mounting plate 10 is fixedly connected to a torsion spring 911. One end of the rotating shaft 910 and the torsion spring 911 is fixedly connected to the same baffle 912. The baffle 912 is movably abutted against the outside of the hand handle 909.

[0032] Using the above method: Push the baffle 912 upwards so that it does not limit the hand lever 909. Then pull the two hand levers 909 outwards. The two hand levers 909 drive the four pull rods 908 and the two movable plates 906 to move outwards. The movable plates 906 drive the locking block 905 outwards, disengaging it from the locking slot 904 and thus not fixing the guide block 903 and the lower mold 3. At this point, the lower mold 3 and the four guide blocks 903 can be disassembled. Then, the lower mold 3 and the four guide blocks 903 corresponding to the upper mold 7 are placed into the guide groove 902. Release the handle 909. At this time, under the elastic force of the return spring 907, the two movable plates 906 and the eight locking blocks 905 move inward and respectively lock into the corresponding slots 904, thereby fixing the guide block 903 and the lower mold 3. Finally, release the baffle 912. At this time, under the torque of the torsion spring 911, the rotating shaft 910 and the baffle 912 deflect downward and reset, and abut against the outside of the handle 909. This prevents the handle 909 and the locking blocks 905 from sliding outward and failing to securely fix the lower mold 3, thereby improving the stability of the lower mold 3 installation.

[0033] Furthermore, two limiting rods 11 are slidably installed on the top of the gantry frame 2. Both limiting rods 11 are fixedly connected to the top of the hollow plate 6, which facilitates the guidance of the hollow plate 6 and makes its lifting and lowering more stable.

[0034] In this invention, during use, the hydraulic cylinder 4 drives the hollow plate 6 and the upper mold 7 to move downward. With the cooperation of the forming cavity of the lower mold 3, the plate can be stamped and formed. Then, the hydraulic cylinder 4 is activated in reverse, causing the upper mold 7 to move upward and reset. The electric push rod 51 is activated, which drives the lifting plate 52 and the two push rods 54 to move upward, so that the formed slide rail can be pushed out of the lower mold 3, thus facilitating the demolding operation of the formed slide rail.

[0035] When stamping slide rails of different specifications is required, the handwheel 81 is used to rotate the shaft 82 and the driving bevel gear 83. The driving bevel gear 83 drives the driven bevel gear 85 and the double-acting screw 86 to rotate. The double-acting screw 86 drives the two moving plates 80, four horizontal plates 89, two vertical plates 88 and two fixing blocks 87 to move away from each other, and causes the fixing blocks 87 to disengage from the fixing groove 84 without fixing the upper mold 7. The upper mold 7 is removed, and then the upper mold 7 of the corresponding specification is placed at the bottom of the hollow plate 6. The shaft 82 is rotated in the opposite direction, so that the two vertical plates 88 and the two fixing blocks 87 move closer to each other. The two vertical plates 88 can clamp and fix the upper mold 7, and the two fixing blocks 87 are engaged in the fixing groove 84, thereby achieving the effect of engagement and fixation, making the fixation of the upper mold 7 more secure.

[0036] Then, push the baffle 912 upwards so that it does not limit the hand lever 909. At this time, pull the two hand levers 909 outwards. The two hand levers 909 drive the four pull rods 908 and the two movable plates 906 to move outwards. The movable plates 906 drive the locking block 905 to move outwards and disengage from the locking slot 904, thus not fixing the guide block 903 and the lower mold 3. At this time, the lower mold 3 and the four guide blocks 903 can be disassembled. Then, put the lower mold 3 and the four guide blocks 903 corresponding to the upper mold 7 into the guide groove 902 and release. When the hand lever 909 is held, under the elastic force of the return spring 907, the two movable plates 906 and the eight locking blocks 905 move inward and respectively lock into the corresponding slots 904, thereby fixing the guide block 903 and the lower mold 3. Finally, the baffle 912 is released. At this time, under the torque of the torsion spring 911, the rotating shaft 910 and the baffle 912 deflect downward and reset, and abut against the outside of the hand lever 909, preventing the hand lever 909 and the locking blocks 905 from sliding outward and failing to securely fix the lower mold 3, thus improving the stability of the lower mold 3 installation.
