[0002] With the continuous development of industrial technology, the precision requirements for mold processing are increasing, and the surface quality of the mold directly affects the quality of the final product. Therefore, molds need to be cleaned regularly during use to remove surface oil, polishing paste, and other stubborn dirt. However, existing cleaning methods generally involve manual cleaning. In manual cleaning, workers need to use brushes dipped in cleaning agents to scrub the inside of the mold cavity to remove attached dirt. However, this manual cleaning method is inefficient and requires a large amount of manpower; therefore, an ultrasonic mold cleaning machine is needed. Utility Model Content

[0006] The cleaning adjustment mechanism enables the action of moving from the top of the cleaning tank to the inside of the cleaning tank for cleaning during mold cleaning.

[0007] The limiting and locking mechanism enables the mold to be limited during the adjustment movement of the cleaning and adjusting mechanism.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-6 An ultrasonic mold cleaning machine includes a cleaning tank 1, with pads 2 installed at the four corners of the bottom of the cleaning tank 1. An ultrasonic mold cleaning mechanism 3 is installed inside the cleaning tank 1, and a cleaning adjustment mechanism 4 is installed above the ultrasonic mold cleaning mechanism 3. A limit locking mechanism 5 is also provided on the surface of the cleaning adjustment mechanism 4.

[0020] The ultrasonic mold cleaning mechanism 3 realizes the action of cleaning the mold by ultrasonic waves after the mold is processed; the ultrasonic mold cleaning mechanism 3 includes a cleaning inner box 31, which is installed inside the cleaning box 1. An ultrasonic transducer 32 is installed at the bottom of the cleaning inner box 31. Multiple ultrasonic transducers 32 are arranged in a rectangular array. An ultrasonic transmitter 33 is installed on the inner bottom wall of the cleaning box 1.

[0021] Specifically, this is implemented by first converting the mains power into a high-voltage, high-frequency AC signal at a specific frequency using an ultrasonic generator. This process includes rectification, filtering, inversion, power amplification, and frequency matching to ensure a stable and efficient output signal that resonates optimally with the transducer.

[0022] Next, the ultrasonic transducer 32 receives the high-frequency electrical signal from the generator and converts it into high-frequency mechanical vibration of the same frequency using the inverse piezoelectric effect. The ultrasonic transducer 32 is tightly connected to the bottom of the cleaning tank 1 through an adhesive layer, efficiently transferring the vibration energy to the cleaning fluid.

[0023] When high-frequency vibrations propagate in a liquid, they generate tens of thousands of tiny pressure waves, creating localized negative pressure zones and producing numerous microbubbles. These cavitation bubbles rapidly expand and collapse instantly with changes in sound pressure, releasing enormous energy and creating localized high temperatures, high pressures, and powerful shock waves. This "cavitation effect" is like countless miniature high-pressure water guns, capable of penetrating deep into the surface and crevices of workpieces to thoroughly remove stubborn dirt such as oil and polishing paste, achieving a thorough and highly precise cleaning effect.

[0024] The cleaning adjustment mechanism 4 realizes the action of moving from the top of the cleaning box 1 to the inside of the cleaning box 1 for cleaning during mold cleaning; the cleaning adjustment mechanism 4 includes an adjustment shaft 41, the bottom ends of the two adjustment shafts 41 are rotatably connected to the inner bottom wall of the inner cleaning box 31, and the arc surfaces of the two adjustment shafts 41 are threadedly connected to the mold placement frame 42, which is composed of multiple flat plates 421, multiple movable seats 422 and multiple fixed seats 423 spliced ​​together.

[0025] Specifically, the threaded connection between the arc surface of the adjusting shaft 41 and the mold placement frame 42 provides a precise adjustment mechanism, allowing the operator to precisely control the movement of the mold placement frame 42 by rotating the adjusting shaft 41. This facilitates adjustment based on the mold cleaning position.

[0026] Multiple movable seats 422 are arranged linearly in a vertical direction and are sequentially stacked and locked to multiple flat plates 421 in a cross-distribution by screws. The two ends of multiple fixed seats 423 are respectively locked to the surfaces of two adjacent flat plates 421 by screws.

[0027] This specific implementation achieves the effect of separating each mold during cleaning and placing them vertically for cleaning.

[0028] The top of the cleaning tank 1 is fixedly installed with columns 43 at both ends. The top of each column 43 is fixedly installed with a top plate 44. The tops of the two adjusting shafts 41 extend through and to the top of the top plate 44. The arc surfaces of the two adjusting shafts 41 are rotatably connected to the surface of the top plate 44 through bearings. The top of the adjusting shafts 41 is fixedly installed with sprockets 45. The surfaces of the two sprockets 45 are connected to chains 46 for transmission.

[0029] Specifically, the design of the sprocket 45 and chain 46 achieves more stable power transmission. The rotation of the adjusting shaft 41 is transmitted to the other end through the chain 46, thereby driving the adjustment of the position of the mold placement frame 42. This facilitates the upward movement of the mold placement frame 42 during cleaning to remove the mold from the cleaning inner box 31, and the downward movement of the mold placement frame 42 into the cleaning inner box 31 during cleaning.

[0030] A motor base plate 47 is installed on the top of the top plate 44. A drive motor 48 is fixedly installed on the surface of the motor base plate 47. The output end of the drive motor 48 is fixedly installed to one end of the relative adjustment shaft 41 through a coupling. A limit switch 49 is installed on the surface of one of the columns 43.

[0031] Specifically, this is implemented by driving a motor 48 to rotate one of the adjustment shafts 41, which in turn controls the rotation of the sprocket 45 on the control surface. Simultaneously, the chain 46 transmits power to control the rotation of the other adjustment shaft 41, thereby enabling the mold placement frame 42 to move and adjust vertically. When the mold placement frame 42 moves upward and contacts the limit switch 49, the drive motor 48 stops operating, and the mold is placed. After placement, the drive motor 48 is restarted to reverse, controlling the mold placement frame 42 to move downward and enter the cleaning inner tank 31. When the cleaning fluid covers the mold placement frame 42, the drive motor 48 is manually stopped, and a button is pressed to drive the ultrasonic mold cleaning mechanism 3 to perform the mold cleaning operation.

[0032] The limiting locking mechanism 5 realizes the limiting action of the mold during the adjustment movement of the cleaning and adjusting mechanism 4; the limiting locking mechanism 5 includes an upper clamping plate 51 and a lower clamping plate 52. The upper clamping plate 51 is located at the top of the plate 421, and the lower clamping plate 52 is located at the bottom of the plate 421. One end of the upper clamping plate 51 and one end of the lower clamping plate 52 are rotatably connected by a pin. A torsion spring 53 is sleeved on the surface of the pin. The clamping force between the upper clamping plate 51 and the lower clamping plate 52 is realized by setting the torsion spring 53. The mold is located between the two limiting locking mechanisms 5.

[0033] Specifically, through the design of the upper clamping plate 51 and the lower clamping plate 52, the limiting and locking mechanism 5 can accurately lock the position of the mold in the cleaning and adjusting mechanism 4, preventing the mold from shifting or loosening during the adjustment process. The clamping force provided by the torsion spring 53 ensures the fastening effect between the two clamping plates, effectively controlling and locking at both ends of the mold, limiting the mold at both ends, and ensuring that the mold does not move or collide during the cleaning process.

[0034] This ultrasonic mold cleaning machine utilizes efficient ultrasonic cleaning technology to achieve precise cleaning of molds. Multiple ultrasonic transducers 32 are installed at the bottom of its cleaning chamber 31, which convert electrical energy into high-frequency mechanical vibration and transmit it to the mold surface through a liquid medium, creating a strong cavitation effect. This thoroughly removes stubborn stains such as oil and polishing paste, ensuring a thorough and highly precise cleaning effect without any blind spots.

[0035] To improve cleaning efficiency, the mold washing machine is also equipped with a cleaning adjustment mechanism 4, which can precisely control the position adjustment of the molds to ensure that each mold is in the optimal cleaning position. This mechanism includes an adjustment shaft 41, a mold placement frame 42, and related connecting devices, enabling precise up-and-down movement of the molds within the cleaning tank 1, preventing mold displacement or collision during the cleaning process. In particular, the design of the sprocket 45 and chain 46 makes the operation of the adjustment shaft 41 more stable and reliable, ensuring accurate mold placement. In addition, the limit locking mechanism 5 effectively fixes the molds, preventing unnecessary movement during adjustment. The upper clamping plate 51 and lower clamping plate 52 achieve clamping force through the torsion spring 53, which can firmly fix the molds in the cleaning position, preventing mold displacement or damage during the cleaning process.

[0036] Working Principle: To ensure cleaning effectiveness, the ultrasonic mold cleaning machine is equipped with a cleaning adjustment mechanism 4. This mechanism, through the design of the adjusting shaft 41, mold placement frame 42, and related sprockets 45 and chains 46, allows for precise vertical adjustment of the mold's position within the cleaning chamber 1. The rotating shaft 41 is controlled by the drive motor 48, thereby enabling the mold placement frame 42 to move vertically. When the mold moves into the inner cleaning chamber 31, the ultrasonic transducer 32 converts electrical energy into high-frequency mechanical vibration, which is transmitted to the mold surface through the cleaning fluid. In the liquid, the pressure waves generated by the ultrasonic waves cause the formation of numerous tiny bubbles. These bubbles expand and rapidly burst under pressure changes; this process is called cavitation. The tiny bubbles generated by cavitation can quickly remove dirt from the mold surface, especially in the tiny crevices, where the cleaning effect is particularly significant. During the cleaning process, the limiting locking mechanism 5 uses the clamping force of the upper clamping plate 51 and the lower clamping plate 52 to fix the mold position, preventing the mold from shifting or colliding with the wall of the cleaning chamber 1. The design of the torsion spring 53 allows the clamping plate to firmly hold the mold, ensuring its stability throughout the cleaning process and preventing damage or displacement of the mold, thereby improving the cleaning safety of the mold. After cleaning, the drive motor 48 is reversed again to move the mold placement frame 42 upwards away from the cleaning chamber 31, and the mold to be cleaned is replaced.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
