Detailed Description of the Invention

[0034] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0035] First Embodiment:

[0036] Please refer to Figures 1 to 6 , the present invention provides a manufacturing device for a quick plug - and - unplug wire harness slide rail of an automotive seat music headrest, including a forming groove 101, a forming seat 102, and a bracket 103. A bottom die 104 is arranged at the inner bottom of the bracket 103, a hydraulic cylinder 105 is arranged above the bracket 103, a stamping die 106 is arranged at the output end of the hydraulic cylinder 105. Installation ends 107 are arranged on the lower end face of the forming groove 101 and the upper end face of the forming seat 102. Both ends of the installation end 107 have two threaded grooves 108. Installation grooves 109 are arranged on the upper end face of the bottom die 104 and the lower end face of the stamping die 106. Two threaded sleeves 110 are rotatably arranged on both sides of the installation groove 109 through bearings. A screw 111 is threadedly arranged in the threaded sleeve 110. Installation covers 112 are arranged on both sides of the forming groove 101 and the forming seat 102. A limiting member is arranged between the screw 111 and the installation cover 112. The two threaded sleeves 110 are connected by a synchronous belt 113 and a synchronous pulley 114. A driven gear 115 is arranged at one end of one of the threaded sleeves 110. Linkage ends 116 are arranged on the front end faces of the forming groove 101 and the forming seat 102. A linkage assembly is arranged in the linkage end 116. The linkage assembly drives the corresponding driven gear 115. The forming groove 101 is connected to the forming seat 102 through the installation end 107, the forming seat 102 is connected to the stamping die 106 through the installation end 107, and the screw 111 is also threadedly arranged in the corresponding threaded groove 108. When the linkage assembly works, it drives the driven gear 115 to rotate, and then makes the threaded sleeve 110 rotate. Since the limiting member restricts the rotation of the screw 111, the screw 111 can only move linearly, realizing the screwing of the screw 111 into or out of the threaded groove 108, completing the connection or disassembly of the mold. This design makes the connection and disassembly between the forming groove 101, the forming seat 102, the bottom die 104, and the stamping die 106 more convenient, without the need for special tools, and can quickly replace the mold to adapt to the production of quick plug - and - unplug wire harness slide rails of automotive seat music headrests with different specifications, improving production efficiency and flexibility.

[0037] Wherein, the limiting member is a polygonal rod 117, the screw rod 111 has a polygonal groove 118 therein, and the polygonal rod 117 extends into the polygonal groove 118. The limiting structure of the polygonal rod 117 and the polygonal groove 118 is simple and reliable, which can effectively ensure that the screw rod 111 only moves linearly when the threaded sleeve 110 rotates, ensuring the stability of the connection and disassembly of the mold, and avoiding the problems of loose connection or difficult disassembly caused by the rotation of the screw rod 111 with the threaded sleeve 110.

[0038] Secondly, the linkage assembly includes two driving gears 119 and a rotating rod 120. Knobs 121 are arranged at both ends of the rotating rod 120. The two driving gears 119 are respectively fixedly connected to the rotating rod 120 and are located on the rotating rod 120. The rotating rod 120 is rotatably connected to the linkage end 116 through a bearing and is located within the linkage end 116. The two driving gears 119 are also respectively meshed with the corresponding driven gears 115 and are located within the mounting cover 112. When the knob 121 is rotated, the rotating rod 120 drives the driving gear 119 to rotate, and the driving gear 119 then drives the driven gear 115 to rotate, thereby driving the threaded sleeve 110 to rotate, realizing the movement of the screw rod 111, and completing the connection or disassembly operation of the mold.

[0039] When using the manufacturing device of a quick - plug - and - unplug wire harness slide rail for an automotive seat music headrest of this embodiment, an operator rotates the knob 121 in the linkage assembly, driving the rotating rod 120 to rotate through the bearing within the linkage end 116. The two driving gears 119 on the rotating rod 120 rotate accordingly. Since the driving gear 119 is meshed with the driven gear 115, the driven gear 115 is driven to rotate. The driven gear 115 drives one of the threaded sleeves 110 to rotate. Also, because the two threaded sleeves 110 are connected by the synchronous belt 113 and the synchronous pulley 114, the two threaded sleeves 110 will rotate synchronously; at this time, due to the cooperation of the polygonal rod 117 and the polygonal groove 118, the rotation of the screw rod 111 is restricted, and when the threaded sleeve 110 rotates, the screw rod 111 can only move linearly, thereby realizing the screwing of the screw rod 111 into or out of the threaded groove 108. After the above - mentioned operation is completed, the installation of the telescopic forming groove 101 and the forming seat 102 of the required components in the slide rail structure is completed; when performing stamping operations, the hydraulic cylinder 105 works, and its output end pushes the stamping die 106 downward to cooperate with the forming groove 101 to stamp the raw material placed in the forming groove 101, making the preliminary shape of the required components in the slide rail structure.

[0040] Second Embodiment:

[0041] Based on the first embodiment, please refer to Figures 7 to 10 , the present invention provides a manufacturing device for a quick-insertion and extraction wire harness slide rail of an automotive seat music headrest, further comprising a discharging mechanism. The discharging mechanism includes a moving plate 201 and an L-shaped seat 202. A pressing handle 203 is hingedly arranged on the moving plate 201. Both sides of the pressing handle 203 are provided with displacement grooves 204. The upper end surface of the moving plate 201 is provided with a discharging rod 205. A lifting seat 206 is arranged below the bracket 103. Both sides of the lifting seat 206 are provided with lifting rods 207. Discharging holes 208 are formed between the bracket 103, the bottom die 104 and the forming groove 101. The moving plate 201 is slidably connected to the L-shaped seat 202 and is located on the L-shaped seat 202, and the discharging rod 205 extends into the discharging hole 208. The L-shaped seat 202 is fixedly connected to the bracket 103 and is located below the bracket 103. The pressing handle 203 is slidably connected to the corresponding lifting rod 207 and is sleeved on the lifting rod 207, and the lifting rod 207 is located in the displacement groove 204. When the pressing handle 203 is pressed downward, under the action of the displacement groove 204 and the lifting rod 207, the moving plate 201 slides upward along the L-shaped seat 202, driving the discharging rod 205 to eject from the discharging hole 208, and ejecting the stamped product from the forming groove 101 to achieve discharging.

[0042] Wherein, the number of the discharging holes 208 and the discharging rods 205 is multiple, and the multiple discharging holes 208 and the discharging rods 205 are arranged symmetrically in pairs and sequentially between the bracket 103, the bottom die 104 and the forming groove 101. Through the design of the multiple symmetrically arranged discharging holes 208 and the discharging rods 205, the uniformity of the force on the product during the discharging process is ensured, the product is prevented from being damaged due to excessive local force, and the quality of the product and the success rate of discharging are improved.

[0043] Secondly, the upper end surface of the moving plate 201 is further provided with a plurality of limit posts 209, and the limit posts 209 are also located between two corresponding discharging rods 205. A return spring 210 is sleeved on the limit posts 209. A limit groove 211 is formed below the bracket 103. The limit posts 209 extend into the limit groove 211, and the return spring 210 abuts between the bracket 103 and the moving plate 201. After the pressing handle 203 is pressed to complete discharging and then the pressing handle 203 is released, under the action of the return spring 210, the return spring 210 abuts between the bracket 103 and the moving plate 201, pushing the moving plate 201 to slide downward along the L-shaped seat 202 to reset. At the same time, the limit posts 209 slide in the limit groove 211 to ensure the accuracy of the reset of the moving plate 201.

[0044] When using the manufacturing device for the quick - plugging wire harness slide rail of an automotive seat music headrest according to this embodiment, after the product stamping is completed, the operator presses down the pressing handle 203. Since the pressing handle 203 is hinged on the moving plate 201 and is slidably connected to the lifting rod 207, and the lifting rod 207 is located in the displacement grooves 204 on both sides of the pressing handle 203, when the pressing handle 203 is pressed, it will rotate around the hinge point as an axis. At the same time, with the cooperation of the displacement groove 204 and the lifting rod 207, the moving plate 201 is driven to slide upward along the L - shaped seat 202. A plurality of unloading rods 205 on the moving plate 201 are pushed upward from the corresponding unloading holes 208, and the products stamped in the forming groove 101 are pushed out to realize unloading. Since the unloading holes 208 and the unloading rods 205 are arranged symmetrically in pairs in sequence, the uniformity of the force on the product is ensured. After unloading, the pressing handle 203 is released. Under the action of the return spring 210, the return spring 210 abuts against the bracket 103 and the moving plate 201, and pushes the moving plate 201 to slide downward along the L - shaped seat 202 to reset. The limiting posts 209 on the moving plate 201 slide in the limiting grooves 211 to ensure the accurate reset of the moving plate 201 and prepare for the next unloading.

[0045] Third Embodiment:

[0046] Based on the second embodiment, please refer to Figures 11 to 13 , the present invention provides a manufacturing device for the quick - plugging wire harness slide rail of an automotive seat music headrest, further including a first positioning member, two second positioning members and a base foot 301.
