[0002] With the continuous development of the automotive industry, the demand for automotive trim strips, as an important component to enhance the aesthetics and quality of a car's appearance, is increasing. During the production process, automotive trim strips typically undergo electroplating to enhance their corrosion resistance, aesthetics, and other properties.

[0003] In traditional electroplating molds, the loading and unloading of decorative strips relies on manual labor. When loading, each strip needs to be picked up, aligned, and clamped manually. When unloading, each strip needs to be removed, sorted, and stacked. This repetitive operation can easily lead to worker fatigue, high labor intensity, low production efficiency, and difficulty in ensuring consistent quality.

[0004] Therefore, there is a particular need for an electroplating mold for automotive trim strips to solve the above problems. Utility Model Content

[0031] Example: An electroplating mold for automotive trim strips, such as Figures 1-15 As shown, the device includes a housing 1, a motor 2, a screw 21, a guide rod 22, a placement plate 23, a connecting rod 24, a gear 3, a screw 31, a clamping block 32, a motor 33, a gear 34, a feeding mechanism, and a loading mechanism. The motor 2 is bolted to the upper left side of the housing 1, and its output shaft extends vertically upwards. The screw 21 is fixedly connected to the output shaft of the motor 2 via a coupling. Three guide rods 22 are fixedly connected to the upper part of the housing 1. Each screw 21 has a connecting rod 24 threaded onto its external surface. Each guide rod 22 has a slidably mounted connecting rod 24. A placement plate 23 is fixedly connected between the lower ends of the four connecting rods 24. The placement plate 23 has drainage holes extending through its thickness to facilitate the discharge of electroplating solution. Motor 2 33 is fixed to the upper front side of housing 1 by bolts. The output shaft of motor 2 33 extends horizontally backward. Screw 2 31 is rotatably set inside the placement plate 23. The front end of screw 2 31 extends to the outside of placement plate 23 and is fixedly connected to gear 1 3. Gear 2 34 is fixedly connected to the output shaft of motor 2 33. Gear 2 34 is located above gear 1 3 and meshes with it. Eight clamping blocks 32 are set on the external thread of screw 2 31. Each pair of symmetrically arranged clamping blocks 32 is a group, and there are four groups in total. The clamping blocks 32 slide in contact with placement plate 23. The clamping surface of the clamping blocks 32 is provided with a rubber protective pad to prevent damage to the surface of the decorative strip during clamping. The feeding mechanism is set on the upper part of housing 1, and the unloading mechanism is set between housing 1 and placement plate 23.

[0032] like Figure 1 and Figures 12-15As shown, the feeding mechanism includes a fixed frame 6, a placement frame 61, a push plate 2 62, a motor 4 63, and a screw 4 64. The fixed frame 6 is also fixed to the upper left side of the housing 1 by bolts and is located behind the motor 2. Four longitudinally distributed placement frames 61 are fixedly connected to the top of the fixed frame 6. The bottom surface of the inner surface of the placement frame 61 is flush with the top surface of the placement plate 23 to ensure a smooth transition of the decorative strip between the placement frame 61 and the placement plate 23. The central symmetry line of each group of two clamping blocks 32 is aligned with the horizontal midpoint of the lower part of the corresponding placement frame 61 to ensure that the material is pushed from the placement frame 61. The decorative strip can accurately enter the clamping area of ​​the two clamping blocks 32. A push plate 2 62 is slidably arranged between the lower parts of the four placement frames 61. The right side of the push plate 2 62 is provided with four push blocks. The four push blocks extend into the four placement frames 61 respectively, and the bottom surface of the push blocks contacts the inner bottom surface of the placement frame 61. The motor 4 63 is fixed to the top right side of the fixing frame 6 by bolts. The output shaft of the motor 4 63 extends horizontally to the left. The screw 4 64 is fixedly connected to the output shaft of the motor 4 63 by a coupling. The screw 4 64 passes through the push plate 2 62 and is threadedly engaged with it.

[0033] like Figure 1 , Figure 2 and Figures 7-11 As shown, the feeding mechanism includes a drive assembly, a support plate 5, a top plate 51, a connecting plate 511, a guide rod 52, a spring 53, a connecting frame 54, and top blocks 55. Eight top plates 51 are slidably arranged inside the placement plate 23, distributed approximately to the left and right. Each top plate 51 has drainage holes extending through its thickness. A support plate 5 is fixedly connected to the center of the bottom of each top plate 51. Two connecting frames 54 arranged side-by-side are fixedly connected between the lower parts of the four support plates 5 on the same side. The upper part of the connecting frame 54 passes through and slides with the placement plate 23. Five top blocks 55 of different sizes are fixedly connected to the upper part of each connecting frame 54. The ten top blocks 55 on the same side are distributed between the four top plates 51 on the same side, thereby filling part of the gaps between the four top plates 51. To facilitate the full lifting of the decorative strip on the placement plate 23, the top surfaces of the placement plate 23, top plate 51, and top block 55 are located on the same horizontal plane to prevent the presence of the top plate 51 and top block 55 from affecting the stable placement of the decorative strip on the surface of the placement plate 23. Eight evenly distributed guide rods 52 are fixedly connected to the left and right sides of the bottom of the placement plate 23. Four connecting plates 511 are fixedly connected to the bottom of each top plate 51. The number of connecting plates 511 is the same as the number of guide rods 52. The guide rods 52 pass through the corresponding connecting plates 511 and slide with them. A spring 53 is sleeved on the outside of each guide rod 52. The upper and lower ends of the spring 53 are connected to the placement plate 23 and the corresponding connecting plate 511, respectively, to provide a reset force for the connecting plate 511. The drive assembly is located at the front of the housing 1.

[0034] like Figure 1 , Figure 2 and Figure 7As shown, the drive assembly includes a motor 4, a screw 41, a slant plate 42, and a push plate 43. The motor 4 is bolted to the front of the housing 1, and its output shaft extends horizontally forward. The screw 41 is fixedly connected to the output shaft of the motor 4 via a coupling. The slant plate 42 is threaded onto the outside of the screw 41, and has two inclined surfaces at its rear. The front of the housing 1 has two square openings for the slant plate 42 to pass through. The rear of the slant plate 42 extends into the housing 1 through the two square openings. The running trajectory of the slant plate 42 intersects with the height of the support plate 5. When the slant plate 42 moves backward, its two rear inclined surfaces can compress the two rows of supports. The plate 5 moves upward, and two push plates 43 arranged side by side are fixedly connected to the top of the inclined plate 42. The lowest point of the inclined plate 42 is at the same horizontal level as the bottom surface of the support plate 5 at its initial position. The vertical distance from the top surface of the top plate 51 to the lowest point of the rear of the push plate 43 is equal to the height of the inclined plate 42. When the inclined plate 42 moves backward and pushes the support plate 5 upward through the inclined surface until the bottom surface of the support plate 5 contacts the top surface of the inclined plate 42, the top plate 51 rises to the predetermined height and lifts the decorative strip on the plate 23. At the same time, the top surface of the top plate 51 is exactly flush with the lowest point of the rear of the push plate 43, ensuring that the decorative strip lifted by the top plate 51 can be accurately pushed away by the push plate 43.

[0035] In use, the operator places the decorative strips to be electroplated sequentially into the four placement frames 61. The bottom decorative strip in the placement frame 61 contacts the top surface of the push plate 2 62. Then, an appropriate amount of electroplating solution is injected into the housing 1. The liquid level of the electroplating solution is lower than the initial height of the placement plate 23. The motor 4 63 is started, and its output shaft drives the screw 4 64 to rotate clockwise, driving the push plate 2 62 to move to the left and completely exit the placement frame 61. At this time, the bottom decorative strip in the placement frame 61 loses its support and falls freely under the action of gravity, contacting the bottom surface of the placement plate 23. The pusher block of pusher plate 2 62 is aligned with the bottom decorative strip. Then, the output shaft of motor 4 63 drives screw 4 64 to rotate counterclockwise, driving pusher plate 2 62 to move to the right. The pusher block extends into the placement frame 61, pushing the bottom decorative strip horizontally onto the placement plate 23, so that the decorative strip enters the clamping area of ​​the corresponding set of two clamping blocks 32. After the decorative strip is pushed into place, the output shaft of motor 4 63 is rotated clockwise, so that screw 4 64 drives pusher plate 2 62 to move to the left again, so that pusher plate 2 62 exits the placement frame 61, completing one automatic feeding cycle.

[0036] Next, start motor 2 33, so that its output shaft drives gear 2 34 to rotate clockwise. Gear 2 34 meshes with gear 1 3, driving screw 2 31 to rotate counterclockwise, so that the two clamping blocks 32 in each group move inward synchronously and clamp the corresponding decorative strip. After clamping is completed, turn off motor 2 33. Then start motor 1 2, so that its output shaft drives screw 1 21 to rotate clockwise, driving left front connecting rod 24 to move the placement plate 23 downward. The placement plate 23 drives the other three connecting rods 24 to move downward. These three connecting rods 24 slide along the three guide rods 1 22 to guide and ensure that the placement plate 23 descends smoothly. During the descent, gear 1 3 disengages from gear 2 34 along with the placement plate 23. When the placement plate 23 descends to the appropriate position and the decorative strip is immersed in the electroplating solution, turn off motor 1 2 and perform electroplating treatment.

[0037] After electroplating is completed, restart motor 2, controlling its output shaft to drive screw 21 to rotate counterclockwise, causing the placement plate 23 to rise back to its initial position. Gear 3 re-engages with gear 34. Turn off motor 2, then start motor 33, controlling its output shaft to drive screw 31 to rotate counterclockwise, causing the four sets of clamping blocks 32 to move outward synchronously, releasing the decorative strip. Then start motor 4, causing its output shaft to drive screw 41 to rotate clockwise, driving the inclined plate 42 to move backward, which in turn drives push plate 43 to move backward. The inclined surface at the rear of push plate 43 contacts and presses the support plate 5, forcing the support plate 5, along with the top plate 51, connecting plate 511, connecting frame 54, and top block 55, to move upward together. As the top plate 51 and top block 55 move upward, they remove the electroplated decorative strip from the placement plate. When the plate 23 is lifted, the connecting plate 511 moves upward, compressing the spring 53. When the support plate 5 rises to a suitable height and its bottom surface contacts the top surface of the inclined plate 42, the top plate 51 and the top block 55 stop moving. The push plate 43 continues to move backward, pushing the decorative strip off the top plate 51 and the top block 55, completing one automatic unloading cycle. When the decorative strip is pushed to the rear of the housing 1, it is picked up manually. Finally, the output shaft of the control motor 4 drives the screw 41 to rotate counterclockwise, driving the inclined plate 42 to move the push plate 43 forward to reset. After the inclined plate 42 disengages from the support plate 5, the spring 53 returns to its original state, pushing the connecting plate 511 downward to reset. The top plate 51, the connecting frame 54, and the support plate 5 move downward together back to the initial position, completing a complete electroplating cycle, which can be repeated for the next batch of work.
