[0002] A cable box, also known as a wire storage box or cable organizer, is a device used to organize and store electrical cords, power strips, chargers, and other items. It can help us solve the problem of tangled wires, tripping hazards, and unsightly appearance. Cable boxes are made of a variety of materials, including plastic, metal, bamboo, and wood. Plastic is lightweight and durable, making it a popular choice for many applications. Plastic cable boxes are injection molded during the manufacturing process.

[0003] In the injection molding process of the wire receiving box, after the workpiece is removed, some impurities may be attached to the outside of the mold core. Because it needs to be manually cleaned before the next processing, frequent cleaning is required after the mold is opened. This operation wastes manpower and is affected by the mold and equipment. When manually cleaning, the cleaning time will be longer due to the angle, and there are certain safety hazards. Utility Model Content

[0025] It should be noted that when the die 1 and the punch 2 of the utility model are separated, the hydraulic cylinder or other driving components penetrate the base 4 and connect with the movable plate 6. By driving the movable plate 6, the ejector 7 is driven to demold the workpiece. While the movable plate 6 moves, it drives the rack 8 to rotate. The rack 8 drives the screw 10 to rotate through the gear 9. Under the action of the thread, the lifting plate 11 moves downward. The lifting plate 11 drives the air nozzle 16 or the mounting plate 14 through the lifting part to blow or sweep the punch 2. When the hydraulic cylinder drives the movable plate 6 to reset, the movable plate 6 drives the lifting part to reset through the rack 8 and the gear 9.

[0026] See also Figure 1 、 2 As shown in Figure 3, one end of the punch 2 is fixedly connected to two supporting side plates 3, one end of the supporting side plate 3 is fixedly connected to a base 4, one side of the base 4 is fixedly connected to a support rod 5, and a movable plate 6 is slidably installed on the outside of the support rod 5. A spring 18 is fixedly connected to the outside of the support rod 5 and located between the punch 2 and the movable plate 6.

[0027] It should be noted that a hole is provided in the middle of the base 4 of the utility model, and the hydraulic cylinder is installed on one side of the base 4 so that its output end passes through the hole and is fixedly connected to the movable plate 6. The movable plate 6 is driven to move on the outside of the support rod 5 by the extension and contraction of the hydraulic cylinder, so that the ejector pin 7 is driven by the movable plate 6 to demold the workpiece, and during this period the workpiece can be blown off by the air nozzle 16.

[0028] See also Figure 1 、 2As shown, the gear 9 is rotationally connected to the punch 2, and the screw 10 is fixed to the gear 9.

[0029] It should be noted that a limit groove is provided on the top of the rack 8 of the utility model, and an L-shaped limit plate is slidably connected to the inside of the limit groove. The limit plate is fixed to the punch 2, and the gear 9 is meshed with the rack 8. When the movable plate 6 moves, it drives the rack 8 to move. The rack 8 drives the screw 10 to rotate through the gear 9, and the screw 10 drives the lifting plate 11 to rise and fall, which is convenient for cleaning the mold core.

[0030] See also Figure 1 、 2 As shown, the lifting part includes a lifting plate 11 threadedly connected to the outside of the screw 10, the middle of the lifting plate 11 is slidably connected to a limit rod 17, the bottom of the limit rod 17 is fixedly connected to the punch 2, one side of the lifting plate 11 is fixedly connected to the lifting rod 12, the bottom of the lifting rod 12 is fixedly connected to the mounting rod 13, and one side of the bottom of the mounting rod 13 is fixedly connected to the mounting plate 14.

[0031] It should be noted that the utility model is provided with two limit rods 17, which are fixedly connected to the outer side of the punch 2. The lifting plate 11 is limited by the sliding connection between the limit rod 17 and the lifting plate 11, so that the lifting plate 11 can move up and down stably along the limit rod 17, and cooperate with the action of the rack 8 and the gear 9. The screw 10 can drive the lifting plate 11 to slide up and down stably, and drive the installation plate 14 to move through the lifting rod 12 and the installation rod 13, so that the cleaning part can be conveniently moved up and down through the installation plate 14.

[0032] See also Figure 3 、 4 As shown, the cleaning portion is a brush 15 fixed to one side of the mounting plate 14 .

[0033] It should be noted that the length of the brush 15 of the utility model is greater than the sum of the lengths of the mold core and the ejector pin 7 extending outward from the mold core, and the mounting plate 14 is tilted downward and in contact with the mold core at a lower position. When the mounting plate 14 drives the brush 15 to move downward, it can sweep down the injection molded parts and clean the designated position of the mold core to prevent impurities from remaining.

[0034] See also Figure 3 As shown, the cleaning portion is a nozzle 16 fixedly connected to one side of the mounting plate 14 .

[0035] It should be noted that a magnetic switch electrically connected to the solenoid valve of the air nozzle 16 is installed on one side of the lifting plate 11 of the utility model, and a strip-shaped magnet is installed at the position of the punch 2 corresponding to the magnetic switch, so that the magnetic switch and the magnet correspond for a longer time. During the descent of the lifting plate 11, continuous power can be achieved in the section where the length of the magnet and the magnetic switch are coordinated, and the workpiece can be separated by the air nozzle 16. When it is raised and reset, the mounting plate 14 drives the air nozzle 16 to clean the mold core.
