A mold cleaning device for a mold production

Abstract

This utility model relates to the field of mold manufacturing and discloses a mold cleaning device for mold production. It solves the problem that when ultrasonic waves propagate in cleaning fluid, they travel almost in a straight line, and the energy radiation has strong directionality. When ultrasonic waves act on a mold with grooves, most of the energy can only directly act on the planar area of ​​the mold or the opening of the groove, making it difficult to effectively penetrate and directly reach the sidewalls and bottom inside the groove. The mold cleaning device includes a cleaning tank, a discharge port located on one side below the cleaning tank, an ultrasonic machine fixedly connected to the outside of the cleaning tank, and a pushing mechanism above the cleaning tank that clamps the mold. After the ultrasonic machine is started, it drives the pull rod and the second guide rod to move along the trajectory of the vortex guide hole, thereby realizing the multi-directional composite movement (rotation + oscillation) of the mold, dynamically adjusting the direction of its grooves to better fit the ultrasonic wave propagation path, significantly improving cleaning efficiency.

Description

Technical Field

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

[0002] In the field of mold cleaning, ultrasonic cleaning technology is widely used in cleaning various molds due to its advantages such as non-contact operation, high cleaning efficiency, and minimal damage to the mold surface. Its principle is based on the cavitation effect generated by high-frequency vibration, which causes tiny bubbles in the cleaning fluid to rapidly burst, releasing a powerful impact force to effectively remove impurities such as oil, debris, and oxides from the mold surface. However, existing ultrasonic cleaning devices face significant technical bottlenecks when dealing with molds with complex structures. Mold surfaces typically have numerous grooves of varying shapes, sizes, and depths. These grooves are crucial for mold forming and directly affect product quality and precision. However, ultrasonic waves propagate almost in a straight line in the cleaning fluid, exhibiting strong directionality in energy radiation. When ultrasonic waves act on a mold with grooves, most of the energy only directly affects the planar area of ​​the mold or the opening of the grooves, failing to effectively penetrate and reach the inner sidewalls and bottom of the grooves. Even if some ultrasonic waves indirectly enter the grooves through reflection, the energy attenuates significantly during reflection, resulting in a substantial reduction in the actual cleaning energy acting on the groove surface. Therefore, stubborn stains in the grooves cannot be thoroughly cleaned, easily creating cleaning blind spots, which greatly reduces the effectiveness of mold cleaning and seriously affects the reusability of the mold and the molding quality of the product. Utility Model Content

[0003] The purpose of this invention is to provide a mold cleaning device for mold production. By using this device, the problem is solved that when ultrasonic waves act on a mold with grooves, most of the energy can only act directly on the flat area of ​​the mold or the opening of the groove, and it is difficult to effectively penetrate and directly reach the side wall and bottom inside the groove.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a mold cleaning device for mold production, comprising a cleaning tank, a discharge port located on one side below the cleaning tank, an ultrasonic machine fixedly connected to the outside of the cleaning tank, a pushing mechanism located above the cleaning tank, and a pulling mechanism located below the pushing mechanism.

[0005] The pushing mechanism includes a first support plate fixedly connected to the top of the cleaning tank, a first cylinder fixedly connected to the top of the first support plate, a first air rod fixedly connected to the output end of the first air cylinder, a support cylinder fixedly connected to the inner upper surface of the first support plate, a first connecting rod rotatably connected to the lower end of the first air rod, a second support plate rotatably connected to the cleaning tank and slidably connected to the outer side of the first connecting rod, a guide groove is provided on the outer surface of the first connecting rod, a first guide rod fixedly connected to the support cylinder is provided inside the guide groove, and a clamp is provided below the second support plate.

[0006] Preferably, the guide groove has a spiral shape, and the guide groove and the first guide rod are fitted with a clearance fit.

[0007] Preferably, the central axis of the first air rod is perpendicular to the lower surface of the cleaning tank.

[0008] Preferably, the pulling mechanism includes a support rod fixedly connected to the lower surface of the second support plate. A groove is provided inside the lower part of the support rod, and a connecting block is provided inside the groove. A second connecting rod is fixedly connected to the lower end of the connecting block. A guide hole is provided inside the second support plate, and a second guide rod is provided inside the guide hole. A sliding groove is provided inside the second connecting rod, and a slider is provided inside the sliding groove. One end of the slider is hinged to a pull rod fixedly connected to the second guide rod. A third connecting rod is fixedly connected to the middle outer side of the first connecting rod. A straight hole is provided inside the third connecting rod, and a third guide rod fixedly connected to the second guide rod is slidably connected to the inner side of the straight hole.

[0012] Preferably, the third guide rod has a cuboid shape.

[0013] 1. The present invention proposes a mold cleaning device for mold production. The mold is clamped by a fixture. After the ultrasonic machine is started, the first cylinder drives the first air rod and the first connecting rod to press down, which causes the guide groove to descend spirally. Due to the clearance fit between the guide groove and the first guide rod, the first connecting rod generates a rotational motion. The rotation is then transmitted through the third connecting rod and the straight hole, which drives the pull rod and the second guide rod to move along the trajectory of the vortex guide hole. This realizes the multi-directional composite motion (rotation + oscillation) of the mold, which dynamically adjusts the direction of the groove to better fit the ultrasonic propagation path and significantly improves the cleaning efficiency.

[0014] 2. This utility model proposes a mold cleaning device for mold production. By periodically moving the mold up and down during operation, it intermittently removes the mold from the cleaning fluid area containing debris, preventing repeated friction of debris against the mold surface. This reduces secondary wear during the cleaning process, protects mold precision, and enhances the thoroughness of cleaning. Attached Figure Description

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.

[0022] Please see Figures 1-5 The present invention provides a technical solution: a mold cleaning device for mold production, including a cleaning box 1, a discharge port 2 located on one side below the cleaning box 1, an ultrasonic machine 5 fixedly connected to the outside of the cleaning box 1, a pushing mechanism 3 located above the cleaning box 1, and a pulling mechanism 4 located below the pushing mechanism 3.

[0023] The pushing mechanism 3 includes a first support plate 301 fixedly connected to the top of the cleaning tank 1. A first cylinder 302 is fixedly connected to the top of the first support plate 301. A first air rod 303 is fixedly connected to the output end of the first cylinder 302. A support cylinder 304 is fixedly connected to the upper inner surface of the first support plate 301. A first connecting rod 305 is rotatably connected to the lower end of the first air rod 303. A second support plate 306, which is vertically slidably connected to the cleaning tank 1, is rotatably connected to the lower outer side of the first connecting rod 305. A guide groove 307 is provided on the outer surface of the first connecting rod 305. A first guide rod 308, which is fixedly connected to the support cylinder 304, is provided inside the guide groove 307. The guide groove 307 has a spiral shape, and the guide groove 307 and the first guide rod 308 are fitted with a clearance fit, so that the first connecting rod 305 can rotate when it moves up and down. A clamp 309 is provided below the second support plate 306.

[0024] The pulling mechanism 4 includes a support rod 401 fixedly connected to the lower surface of the second support plate 306. A groove 402 is provided inside the lower part of the support rod 401. A connecting block 403 is provided inside the groove 402. The inner surface of the groove 402 fits against the outer surface of the connecting block 403. The connecting block 403 has a spherical shape, allowing it to rotate within the groove 402. A second connecting rod 404 is fixedly connected to the lower end of the connecting block 403. A guide hole 405 is provided inside the second support plate 306. A second guide rod 406 is provided inside the guide hole 405. A sliding groove 407 is provided inside the second connecting rod 404. A slider 408 is provided inside the sliding groove 407. One end of the slider 408 is hinged to a pull rod 409 fixedly connected to the second guide rod 406. A third connecting rod 409 is fixedly connected to the outer middle part of the first connecting rod 305. The rod 410 has a straight hole 411 inside. A third guide rod 412, which is fixedly connected to the second guide rod 406, is laterally slidably connected to the inside of the straight hole 411. The guide hole 405 has a spiral shape and the guide hole 405 and the second guide rod 406 are fitted with a clearance fit, so that the second guide rod 406 can move outward when the guide hole 405 moves. The width of the slider 408 at the end away from the third connecting rod 410 is greater than the width of the slider 408 at the end close to the third connecting rod 410. The outer surface of the slider 408 is in contact with the inner surface of the groove 407, and the central axis of the slider 408 is parallel to the central axis of the second connecting rod 404, so that the slider 408 will not move out of the inner side of the groove 407 when it moves inside the groove 407. The third guide rod 412 has a cuboid shape.

[0025] When cleaning the mold, clamp 309 is used to hold the mold. The ultrasonic machine 5 is started, and the first cylinder 302, the first air rod 303, and the first connecting rod 305 are activated to move downwards, causing the guide groove 307 to move downwards. Because the guide groove 307 has a spiral shape and the guide groove 307 and the first guide rod 308 are in a clearance fit, the first connecting rod 305 rotates, driving the third connecting rod 410 and the straight hole 411 to rotate. This causes the third guide rod 412, the pull rod 409, and the second guide rod 406 to rotate. Because the guide hole 405 has a vortex shape and the guide hole... The second guide rod 406 and the third guide rod 412 are fitted with a clearance fit, which causes the second guide rod 406 to move downward and outward along the trajectory of the guide hole 405. This causes the third guide rod 412, the pull rod 409, and the second guide rod 406 to move outward, thereby driving the slider 408 to move outward. Because the inner side of the groove 402 is in contact with the outer side of the connecting block 403, and the connecting block 403 has a spherical shape, the second connecting rod 404 and the clamp 309 swing, which causes the mold to swing and rotate, so that the orientation of the groove on the mold changes, which better matches the direction of sound wave propagation of the ultrasonic machine 5, resulting in a better cleaning effect.

[0026] Because the mold moves up and down when it rotates and swings, it can detach from the area where the debris has just been removed, reducing wear and tear on the mold and resulting in better cleaning.
