Description

Technical Field

[0001] This utility model relates to the field of mold cleaning technology, specifically an automatic cleaning device for injection molding. Background Technology

[0002] Injection molds are tools used to produce plastic products. Based on molding characteristics, injection molds are classified into two types: thermosetting plastic molds (automotive molds) and thermoplastic plastic molds. Based on molding processes, they are classified into transfer molds, blow molds, and injection molds. Hot press molds can be further divided into three types based on overflow method: overflow type, semi-overflow type, and non-overflow type. Injection molds can be divided into two types based on gating system: cold runner molds and hot runner molds. After use, molds should be cleaned and sealed for maintenance to keep their surfaces clean and smooth.

[0003] Existing cleaning methods for injection molds are inefficient because they rely on manual cleaning. However, the internal structure of injection molds is complex and difficult to touch directly with the hands. Furthermore, manual cleaning can lead to incomplete rinsing due to the hands obstructing the water flow, making it difficult to ensure the uniformity of cleanliness. Utility Model Content

[0015] 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.

[0016] Please see Figures 1-5 This utility model provides a technical solution, including a shell 1, four sets of columns 2 connected to the top of the shell 1, a side plate 3 connected between two sets of columns 2, a top plate 4 connected to the top of the columns 2, a cavity 5 opened inside the shell 1, a cleaning tank 6 connected to the top of the shell 1, a clamping and flipping mechanism 7 connected inside the cleaning tank 6, a drain pipe 8 connected to the bottom of the cleaning tank 6, an electric push rod 10 connected to the bottom of the top plate 4, a connecting plate 11 connected to one end of the electric push rod 10, a water storage tank 12 and a booster pump 15 connected to the top of the top plate 4, a connecting pipe 16 connected to one side of the water storage tank 12, the connecting pipe 16 connected to the booster pump 15, a corrugated pipe 17 connected to one end of the connecting pipe 16, a plurality of nozzles 18 connected to the bottom of the connecting plate 11, a control circuit board 19 connected to one side of the cavity 5, and a control panel 22 connected to one side of the side plate 3.

[0017] The clamping and flipping mechanism 7 includes a protective shell 71 connected to one side of the cleaning tank 6. A motor 72 is connected inside the protective shell 71. A rotating shaft 73 is connected to the output end of the motor 72. One end of the rotating shaft 73 extends into the cleaning tank 6 and is connected to a rectangular frame 74. Telescopic rods 75 are connected to all four sides of the inner circle of the rectangular frame 74. A clamping plate 76 is connected to the telescopic end of the telescopic rods 75. A rubber pad 77 is connected to one side of the clamping plate 76. The function of the telescopic rods 75 and clamping plates 76 on all four sides of the inner circle of the rectangular frame 74 is to ensure that the items to be cleaned are fully and evenly clamped in the cleaning tank 6, so that the cleaning liquid or water can more easily contact all surfaces of the items, thereby improving the cleaning effect.

[0018] A wastewater storage tank 9 is connected to the bottom of the cavity 5 and is located directly below the drain pipe 8. The purpose of the wastewater storage tank 9 is to ensure that the wastewater generated during the cleaning process can flow smoothly and centrally into the wastewater storage tank 9, avoiding the scattering and accumulation of wastewater inside the equipment or in the surrounding environment, and keeping the equipment clean and hygienic.

[0019] Multiple sets of ultrasonic transducers 20 are connected to the surface of the cleaning tank 6. One end of each ultrasonic transducer 20 is connected to an ultrasonic output end 21. The function of the ultrasonic transducer 20 is to convert electrical energy into ultrasonic vibration energy and transmit this energy to the cleaning fluid through the ultrasonic output end 21. The tiny bubbles (cavitation effect) generated by the ultrasonic waves in the cleaning fluid can expand and burst rapidly, releasing a powerful impact force, thereby effectively removing stains and dirt from the surface of the items to be cleaned.

[0020] A water inlet pipe 13 is connected to one side of the water storage tank 12, and a transparent scale plate 14 is connected to the other side of the water storage tank 12. The purpose of the water inlet pipe 13 is to allow the operator to easily add water or other cleaning fluid to the water storage tank 12, and the transparent scale plate 14 allows the operator to visually view the water level in the water storage tank 12.

[0021] The control circuit board 19, ultrasonic transducer 20, ultrasonic output terminal 21, and control panel 22 are connected by signals. The function of the control circuit board 19 is to achieve precise control of the ultrasonic transducer 20, including the adjustment of parameters such as switching, frequency, and power. The ultrasonic output terminal 21 can provide real-time feedback of the working status of the ultrasonic transducer 20 to the control circuit board 19. The control panel 22 allows the operator to flexibly adjust the cleaning parameters according to actual needs, such as the frequency, power, and working time of the ultrasonic waves.

[0022] Two sets of door panels 23 are hinged on one side of the outer casing 1. A handle 24 is connected to one side of the door panel 23. The function of the handle 24 is to connect the door panel 23 to the outer casing 1 by means of hinge, so that the door panel can be easily opened and closed. The handle 24 makes the opening and closing of the door panel more convenient.

[0023] Working principle: The operator sets cleaning parameters, such as cleaning time, ultrasonic intensity, and water pressure, through the control panel 22. Then, the mold is placed in the clamping and flipping mechanism 7, and the telescopic rod 75 extends inward to clamp the mold through the clamping plate 76. The rubber pad 77 prevents the mold from slipping. Next, the cleaning fluid is added to the cleaning tank 6. After starting the device, the control circuit board 19 controls each component to start working according to the preset parameters. The ultrasonic transducer 20 converts electrical energy into ultrasonic vibration energy and transmits this energy to the cleaning fluid through the ultrasonic output terminal 21. The tiny bubbles (cavitation effect) generated by the ultrasonic waves in the cleaning fluid can rapidly expand and burst, releasing a powerful impact force. This process cleans the mold first. After cleaning, the plug on the drain pipe 8 is removed, and the cleaning fluid is discharged into the wastewater storage tank 9 through the drain pipe 8. Then, the booster pump 15 is started, and the water in the water storage tank 12 is pressurized by the booster pump 15. It then enters the connecting plate 11 through the connecting pipe 16 and the corrugated pipe 17, and then sprays high-pressure water onto the mold through the nozzle 18. At the same time, the motor 72 of the clamping and flipping mechanism 7 is started, driving the rotating shaft 73 and the rectangular frame 74 to rotate. The telescopic rod 75 and the clamping plate 76, together with the rubber pad 77, clamp the injection molded part and flip it as the rectangular frame rotates, so as to achieve the effect of thoroughly cleaning the mold. Then, the clamping and flipping mechanism 7 is reset, waiting for the next cleaning task.
