Description

Technical Field

[0001] This utility model relates to the field of mold production, specifically a marking device for mold production. Background Technology

[0002] Publication number CN218016428U discloses a multi-faceted marking device for mold production, including a worktable, a movable seat structure, a laser marking mechanism, a rotating seat structure, a mounting seat, a lifting seat structure, and a follow-up clamping structure. The worktable has multiple support legs at its bottom, and two longitudinally spaced grooves on its upper surface. In the mold manufacturing industry, marking is often performed on the mold surface or specific structural parts to achieve full lifecycle management, assembly precision control, and intellectual property protection. In recent years, with the increasing complexity and precision of mold designs, the demand for marking inside mold holes has been increasing, such as cooling holes and guide post holes in stamping dies, requiring marking of hole diameter, tolerance grade, material information, or unique traceability codes. Compared to marking the mold surface, marking inside holes faces challenges such as enclosed space, poor accessibility, and high operational precision requirements, and laser marking technology is often used.

[0003] Laser marking technology, with its advantages of non-contact and high precision, is widely used for marking inside mold holes. However, during the processing, the mold material is instantly vaporized and melted by the high-energy laser beam, generating a large amount of metal vapor, smoke, and splatter particles. These fumes are difficult to expel quickly due to the closed structure of the channels and easily adhere to the optical components of the marking device (such as the focusing lens and reflector of the laser head). On the one hand, the deposited fumes on the optical lenses reduce light transmittance, leading to laser energy attenuation and spot distortion, resulting in blurry or uneven marking effects, affecting the marking quality and accuracy. On the other hand, metal particles entering moving parts exacerbate mechanical wear, shorten the equipment's lifespan, and may even cause the marking device to jam or misalign, significantly reducing production efficiency. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4The present invention provides a technical solution: a marking device for mold production, comprising a base 1, a first support plate 2 fixedly connected to one side of the upper end of the base 1, a first cylinder 3 fixedly connected to the upper end of the first support plate 2, a first air rod 4 fixedly connected to the output end of the first air rod 3, a pressure plate 5 fixedly connected to the lower end of the first air rod 4, a second cylinder 6 fixedly connected to the other side of the upper end of the base 1, a second air rod 7 fixedly connected to the output end of the second cylinder 6, a marking device 8 fixedly connected to one end of the second air rod 7, a pushing mechanism 9 provided below the second air rod 7, and a sliding mechanism 10 provided on one side of the pushing mechanism 9;

[0022] The pushing mechanism 9 includes a second support plate 901 fixedly connected below the second air rod 7. A first guide groove 902 is formed on the upper surface of the second support plate 901. A first guide rod 903 is disposed inside the first guide groove 902. A connecting rod 904 is fixedly connected to the upper end of the first guide rod 903. A sliding plate 905 is fixedly connected to one end of the connecting rod 904. A third support plate 906, fixedly connected to the second support plate 901, is slidably connected to one side of the sliding plate 905. A push plate 907 is disposed on one side of the third support plate 906. A cleaning cloth 908 is disposed inside the push plate 907. Point a is provided on the outer side of the first guide groove 902 near the second cylinder 6. Point b is provided on the inner side of one end of cylinder 6, point c is provided on the outer side of the end of first guide groove 902 away from second cylinder 6, and point d is provided on the inner side of the end of first guide groove 902 away from second cylinder 6. Point a of first guide groove 902 is closer to first support plate 2 than point b of first guide groove 902, and point c of first guide groove 902 is farther away from first support plate 2 than point d of first guide groove 902. This allows the first guide rod 903 to move to the side of first guide groove 902 closer to first support plate 2 when it moves to point a of first guide groove 902 and moves back, and the first guide rod 903 to the side of first guide groove 902 away from first support plate 2 when it moves to point c of first guide groove 902 and moves back.

[0023] The third support plate 906 has a second guide groove 11 inside. The sliding mechanism 10 includes a second guide rod 1001 disposed inside the second guide groove 11. The second guide rod 1001 is fixedly connected to the push plate 907. The slide plate 905 has a third guide groove 1003 inside. The third guide groove 1003 has a third guide rod 1004 fixedly connected to the push plate 907 inside. The second guide groove 11 has a vertical straight shape. The second guide rod 1001 has a cuboid shape. The second guide rod 1001 is slidably connected to the third support plate 906. The third guide groove 1003 has an inclined straight shape. The third guide groove 1003 and the third guide rod 1004 are fitted with a clearance fit. This allows the slide plate 905 to move along the trajectory of the second guide groove 11 when it moves.

[0024] When marking is required on the inner hole of the mold, the mold is placed in a suitable position on the base 1. The first cylinder 3, the first air rod 4, and the pressure plate 5 are activated to clamp and fix the mold. The second cylinder 6 is activated to drive the second air rod 7 and the marking device 8 to move towards the inner hole of the mold. After marking is completed, the second air rod 7 drives the second support plate 901 to move back, which in turn drives the first guide groove 902 to move back. Because point a of the first guide groove 902 is closer to the first support plate 2 than point b, and point c of the first guide groove 902 is farther away from the first support plate 2 than point d, when the first guide rod 903 moves to point c of the first guide groove 902 and moves back, the first guide rod... 903 can move to the side away from the first support plate 2. The first guide rod 903 drives the connecting rod 904 and the slide plate 905 to move away from the first support plate 2, so that the third guide groove 1003 moves. Since the appearance structure of the second guide groove 11 is a vertical straight line, the appearance structure of the second guide rod 1001 is a cuboid, and the connection between the second guide rod 1001 and the third support plate 906 is a sliding connection, the appearance structure of the third guide groove 1003 is an inclined straight line, and the cooperation between the third guide groove 1003 and the third guide rod 1004 is a clearance fit, the second guide rod 1001, the push plate 907, and the cleaning cloth 908 move towards the center to clean the surface of the coding device 8.

[0025] As the second air spring 7 and the coding device 8 move back, the first guide rod 903 moves to the side of the first guide groove 902 close to the first support plate 2, causing the third guide rod 1004 and the cleaning cloth 908 to reset, so that the cleaning cloth 908 opens to both sides to avoid secondary pollution.

[0026] As the coding device 8 moves out of the mold's inner hole, it can be cleaned immediately because most of the dirt is in a relatively soft state at this time, making it easier to remove.
