Description

Technical Field

[0001] The utility model relates to the field of injection molds, in particular to a positioning device for an injection mold of a lamp cover. Background Art

[0002] A motorcycle's lighting system typically includes a headlight, turn signals, and taillight. The headlight is the primary light source used to illuminate the road ahead when the motorcycle is driving at night. There are generally two types of headlights: halogen headlights and LED headlights. Halogen headlights use tungsten filaments as a light source, while LED headlights use light-emitting diodes as a light source. Some motorcycles are also equipped with dual or quad headlight systems to provide better lighting effects.

[0003] The lamp cover in the motorcycle headlight requires the use of an injection mold during the production process. The existing injection mold is generally installed and positioned by screws during the injection molding process. It is necessary to manually place the injection mold accurately on the injection molding station, and then use screws or bolts to fix the injection mold. After the fixation is completed, the injection molding operation can be carried out. During the installation process, the mold needs to be accurately aligned with the threaded holes on the injection molding station, which takes a lot of time for the staff to operate. Not only is the installation efficiency low, but the disassembly and assembly are inconvenient. When different models of workpieces need to be processed, different molds need to be replaced, which often takes a lot of time to perform the replacement operation, reducing work efficiency. After the bolts and other fixings are disassembled and installed many times, wear will occur between the threads, which makes the injection mold positioning unstable and inaccurate, affecting the quality of the injection molded products.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the utility model.

[0022] See also Figure 1-3 The utility model provides a technical solution: a lamp cover injection mold positioning device, including a mold table 1, a mold body 6 is provided in the upper middle part of the mold table 1, a connecting plate 9 is fixedly connected to the inner middle part of the mold table 1, a motor 15 is fixedly connected to the bottom of the mold table 1, an output end of the motor 15 is fixedly connected to a second rotating rod 17, and a second gear 16 is fixedly connected to the second rotating rod 17. By starting the motor 15, the second rotating rod 17 and the second gear 16 on the output end can be driven to rotate;

[0023] The middle part of the connecting plate 9 is rotatably connected with a rotating rod 14, and a gear 13 is fixedly connected to the rotating rod 14. The gear 13 and the gear 2 16 are meshed with each other. The top of the rotating rod 14 is fixedly connected with a rotating plate 12. The four ends of the rotating plate 12 are fixedly connected with a rotating shaft 2 18. The inside of the rotating shaft 2 18 is rotatably connected with a connecting rod 19. The four inner ends of the connecting plate 9 are all provided with movable plates 11. The inner end of the movable plate 11 is fixedly connected with a rotating shaft 10. The other end of the connecting rod 19 is rotatably connected to the rotating shaft 10. Under the action of meshing, the gear 13 and the rotating rod 14 can be driven to rotate, thereby driving the rotating plate 12 at the upper end to rotate. Since the rotating plate 12 and the movable plate 11 are connected by a connecting rod 19, and both ends of the connecting rod 19 are rotatably connected, the rotating plate 12 can drive the four movable plates 11 to move inward at the same time during the rotation process.

[0024] A slider 4 is fixedly connected to the top of the movable plate 11. A slide groove 2 is opened at the four ends of the top of the mold table 1. A slide rod 3 is fixedly connected to the inside of the slide groove 2. The slider 4 is slidably connected to the slide rod 3. The slider 4 passes through the slide groove 2 and is fixedly connected to the clamping plate 5 upward. The movable plate 11 can be connected to the clamping plate 5 through the slider 4, and the slide rod 3 can limit the clamping plate 5 to improve the stability of the clamping plate 5 during movement.

[0025] A chute 27 is provided inside the connecting plate 9, and a slider 28 is fixedly connected to the bottom of the movable plate 11. The slider 28 is slidably connected to the inside of the chute 27. By setting the chute 27 and the slider 28, the position of the movable plate 11 can be restricted to ensure that when the rotating plate 12 rotates, the movable plate 11 can only move in the direction of the chute 27 to ensure the positioning and clamping ability of the entire device.

[0026] Working principle: When in use, select a mold body 6 of appropriate size, place it on the mold table 1, start the internal motor 15, and the motor 15 drives the rotating rod 2 17 and the gear 2 16 to rotate. Under the meshing action, it can drive the gear 13 and the rotating rod 14 to rotate, thereby driving the rotating plate 12 at the upper end to rotate. Since the rotating plate 12 and the movable plate 11 are connected by a connecting rod 19, and both ends of the connecting rod 19 are connected in a rotating manner, the rotating plate 12 can drive the four movable plates 11 to move inward at the same time during the rotation process, and the clamping plate 5 is connected to the movable plate 11 through the slider 14. Therefore, the movable plate 11 can drive the clamping plate 5 to move during the movement, realizing the rapid positioning and clamping function of the four ends of the mold body 6 to ensure the stability of the mold body 6 during injection molding. The device is suitable for positioning molds of different sizes, greatly improving its injection molding efficiency.
