[0002] Mold cleaning equipment is a specialized device used to clean the surface and interior of molds in industrial production. Its core function is to ensure the normal operation of the mold and the precision of subsequent products.

[0003] In the prior art, CN221934799U discloses a mold cleaning device. By setting a height adjustment mechanism and a lateral adjustment mechanism that cooperate with the clamping mechanism, the position of the clamped shower head mold can be freely adjusted to accurately locate the cleaning position. The cleaning force and degree can also be controlled by controlling the distance between the mold and the nozzle, which enhances the flexibility of the device. However, the prior art does not have a drying device. If the mold is not dried after cleaning, it will cause the mold to rust, shorten its life and cause product quality defects. Therefore, a mold cleaning device is proposed. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described below.

[0025] To address the problems existing in the background art, this application proposes the following technical solution: a mold cleaning device, comprising a housing 1, with a horizontally placed perforated plate 8 fixedly installed inside the housing 1, dividing the housing 1 into a cleaning chamber 2 and a liquid storage chamber 3. The cleaning chamber 2 is located above the liquid storage chamber 3. A door 19 is hinged to the opening of the cleaning chamber 2, and tempered glass 20 is embedded in the door 19. A pair of vertically placed support rods 7 are fixedly installed on the top surface of the perforated plate 8, and a mold body 11 is rotatably connected between the two support rods 7. A rotating plate 4 is rotatably connected to the adjacent surfaces of the two support rods 7. A fixed plate 5 is provided at the front. The rotating plate 4 and the fixed plate 5 are connected by an anti-loosening component 6. The mold body 11 is clamped between the rotating plate 4 and the fixed plate 5. The extension end of the servo motor 13 is fixedly connected to one of the rotating plates 4. The servo motor 13 is fixedly installed on the outer surface of the housing 1. The main shaft of the servo motor 13 rotates through the support rod 7 and extends inward. The air distribution box 10 is fixedly installed on the inner top surface of the cleaning chamber 2. The hot air gun 12 is fixedly installed on the outer top surface of the housing 1. The air outlet of the hot air gun 12 penetrates the inner top surface of the cleaning chamber 2 and extends inward, and is fixedly connected to the air inlet of the air distribution box 10.

[0026] First, the operator places the mold body 11 between the rotating plate 4 and the fixed plate 5, and tightens it with the anti-loosening components 6 (such as bolts and anti-loosening nuts) to ensure that the mold does not shake during subsequent rotation. Then, the box door 19 is closed, forming a closed space to prevent the cleaning liquid from splashing out. The operator can observe the internal situation in real time through the tempered glass 20. During the cleaning stage, the servo motor 13 is started, and its main shaft passes through the support rod 7 to drive the rotating plate 4 to rotate, which in turn drives the mold body 11 to rotate intermittently between the two support rods 7 (pausing for a preset time after each rotation angle) to ensure that all surfaces of the mold are covered with cleaning liquid. During the dehydration stage, the servo motor 13 switches to continuous rotation mode, and the mold rotates at high speed with the rotating plate 4, using centrifugal force to shake off the residual water on the surface. At the same time, the hot air gun 12 is started, and the generated hot air is sent into the air distribution box 10 through the pipe. After being dispersed by the internal guiding structure of the air distribution box 10, it is blown evenly onto the mold surface from multiple air outlets to accelerate the evaporation of moisture. Furthermore, the waste liquid generated during the cleaning process drips through the perforated holes of the perforated plate 8 into the lower liquid storage chamber 3, achieving separation of cleaning and waste liquid collection. The beneficial effects are: the anti-loosening component 6 ensures the mold is firmly fixed and prevents it from falling off during rotation; intermittent rotation improves cleaning uniformity, while continuous rotation combined with hot air drying significantly shortens drying time; the design of the perforated plate 8 and the liquid storage chamber 3 facilitates centralized waste liquid treatment, and the tempered glass 20 allows for convenient real-time monitoring, thus improving overall operational safety and efficiency.

[0027] In this embodiment, a cleaning fluid filter box 16 is provided on the outside of the housing 1. A drain pipe 14 is fixedly connected to the bottom surface of the liquid storage chamber 3. The end of the drain pipe 14 is fixedly connected to the inlet of the cleaning fluid filter box 16. A nozzle 9 of the same height as the mold body 11 is fixedly installed on the front vertical surface of the cabinet door of the cleaning chamber 2. A delivery pipe 17 is fixedly connected to the inlet of the cleaning fluid filter box 16. The other end of the delivery pipe 17 penetrates the inner wall of the cleaning chamber 2 and extends inward to be fixedly connected to the inlet of the nozzle 9. An injection pipe 15 is provided on the outside of the housing 1. The end of the injection pipe 15 is fixedly connected to the inner side wall of the liquid storage chamber 3. A second solenoid valve 22 is fixedly installed inside the drain pipe 14. A first solenoid valve 21 is fixedly installed inside the injection pipe 15.

[0028] Initially, the operator injects cleaning fluid into the storage chamber 3 through the injection pipe 15 (at this time, the controller 18 opens solenoid valve 21, and the liquid flows into the storage chamber 3 through the injection pipe 15, closing solenoid valve 21 after reaching the preset liquid level). During cleaning, the controller 18 opens solenoid valve 22, and the cleaning fluid in the storage chamber 3 flows into the cleaning fluid filter tank 16 through the drain pipe 14 under the action of gravity or the pump. The filter screen inside the filter tank (such as a metal mesh or non-woven fabric filter screen) removes mold debris, oil stains, and other impurities from the liquid. The filtered cleaning fluid is delivered to the nozzle 9 through the delivery pipe 17 (powered by a built-in micro pump). Since the nozzle 9 is at the same height as the mold body 11, the sprayed cleaning fluid (such as a high-pressure column or mist) can directly act on the mold surface, achieving thorough rinsing in conjunction with the intermittent rotation of the mold. After cleaning, the controller 18 closes solenoid valve 22 and the power components of the cleaning fluid filter tank 16, stopping the liquid circulation. The beneficial effects are as follows: the cleaning fluid filter box 16 enables liquid recycling, reducing consumable consumption; the equal height design of the nozzle 9 improves the targeting of rinsing and provides better cleaning effect; the solenoid valve 1 21 and solenoid valve 22 precisely control the liquid circuit opening and closing, avoiding resource waste, reducing overall operating costs and making it more environmentally friendly.

[0029] In this embodiment, a controller 18 is fixedly installed on the outer surface of the housing 1. The controller 18 is electrically coupled to the hot air gun 12, the servo motor 13, the cleaning fluid filter box 16, the solenoid valve 21, and the solenoid valve 22.

[0030] The controller 18, as the core control unit, automates the entire process. The specific operation is as follows: After the operator secures the mold and closes the door 19, they initiate a preset program via the controller 18's control panel (or touchscreen). First, the controller 18 sends a signal to the servo motor 13, causing it to enter intermittent rotation mode; simultaneously, it sends an opening signal to the second solenoid valve 22 and starts the power system of the cleaning fluid filter tank 16, initiating the cleaning process. At this time, the nozzle 9 continuously sprays cleaning fluid, working in conjunction with the mold rotation to complete a thorough rinse. Second, when the cleaning time reaches the preset value, the controller 18 sends a stop signal to the cleaning fluid filter tank 16 and closes the second solenoid valve 22, stopping the fluid supply. Third, the controller 18 adjusts the operating parameters of the servo motor 13, causing it to enter continuous rotation mode, using centrifugal force to remove moisture from the mold surface; simultaneously, it sends a start signal to the hot air gun 12, which begins heating and blowing hot air evenly onto the mold via the air distribution box 10. In the fourth step, after the dehydration and drying time reaches the preset value, the controller 18 sends a stop signal to the servo motor 13 and the hot air gun 12, and all components stop operating, completing the entire operation. The benefits are: automated control reduces manual intervention and avoids operational errors; each step is connected in an orderly manner according to preset logic, improving operational consistency and efficiency.

[0031] In this embodiment, the cleaning fluid filter box 16 is a prior art product. Those skilled in the art can select different models of cleaning fluid filter boxes 16 according to actual conditions. The fixing and installation method of the cleaning fluid filter box 16 can be fixed using other existing technologies, which will not be elaborated here.

[0032] In this embodiment, all components in the cleaning chamber 2, as well as solenoid valve 21, solenoid valve 22, and perforated plate 8, need to be treated with anti-corrosion measures to extend their service life.

[0033] To ensure that those skilled in the art can fully understand the technical solution, the usage method of this embodiment is as follows: the rotating plate 4 and the fixed plate 5 are used in conjunction with the anti-loosening component 6 to fix the mold body 11 between the rotating plate 4 and the fixed plate 5. Then, the box door 19 is closed, and the servo motor 13 is started by the controller 18 to achieve intermittent rotation. The main shaft of the servo motor 13 will drive the rotating plate 4 to rotate. The controller 18 opens the second solenoid valve 22 and starts the cleaning fluid filter box 16 to rinse the mold body 11 with cleaning fluid. After rinsing, the cleaning fluid filter box 16 is closed and the second solenoid valve 22 is closed. The controller 18 keeps the servo motor 13 rotating to splash the water off the mold body 11. At the same time, the controller 18 starts the hot air gun 12 to dry the mold body 11. After drying, everything stops.
