In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0048] In the related art, after the casting of the product is completed, the mold shell needs to be cleaned to prevent the impurities remaining on the mold shell from affecting the next casting. Regarding the cleaning of the mold shell, taking CN112657920A as an example, a cavity shell with an opening and a drain port is set on the frame, a support for supporting the module is set at the opening, a nozzle device that is connected to the cleaning liquid tank is set on the support, and the drain port is connected to the wastewater tank. When cleaning the mold shell, the mold shell is placed on the support, and the module is cleaned using the nozzle device, and the cleaned wastewater is collected in the wastewater tank. Although the above scheme can realize the cleaning of the module, it does not recycle and reuse the wastewater, the cost is relatively high, and the single cleaning liquid has a poor cleaning effect on the module.

[0049] In order to solve the above problems, Figure 1 to Figure 6As shown, this embodiment provides a mold cleaning device. The mold cleaning device includes a cleaning chamber 100, a filtering structure 300 and two circulation drive structures 200, wherein a first liquid discharge chamber 130 and a second liquid discharge chamber 140 are provided in the cleaning chamber 100, and a liquid inlet and a liquid outlet are provided on the first liquid discharge chamber 130 and the second liquid discharge chamber 140, respectively, and a hollow plate 110 is provided on the cleaning chamber 100, and the hollow plate 110 connects the liquid inlets on the first liquid discharge chamber 130 and the second liquid discharge chamber 140 to the outside world. The mold is placed in the cleaning chamber 100. On the hollow plate 110, a filtering structure 300 is provided in the first liquid drainage chamber 130 and the second liquid drainage chamber 140, and two circulation driving structures 200 are respectively connected to the liquid outlets of the first liquid drainage chamber 130 and the second liquid drainage chamber 140. Any one of the two circulation driving structures 200 drives the cleaning liquid to circulate between the mold shell and the first liquid drainage chamber 130, and the other drives the cleaning liquid to circulate between the mold shell and the second liquid drainage chamber 140. The cleaning liquids driven by the two circulation driving structures 200 are different.

[0050] The mold shell cleaning device is provided with a first liquid discharge chamber 130 and a second liquid discharge chamber 140 isolated from each other in a cleaning chamber 100, and the liquid inlets of the first liquid discharge chamber 130 and the second liquid discharge chamber 140 are connected to the outside by using a hollow plate 110 on the cleaning chamber 100, and filtering structures 300 are respectively provided in the first liquid discharge chamber 130 and the second liquid discharge chamber 140, and the liquid in the first liquid discharge chamber 130 and the second liquid discharge chamber 140 is filtered by using the filtering structure 300, and two circulation drive structures 200 are respectively connected to the first liquid discharge chamber 130 and the second liquid discharge chamber 140. The liquid outlets of the second liquid discharge chamber 140 are connected to each other. When the mold shell is placed on the hollow plate 110, any one of the two circulation driving structures 200 can drive the cleaning liquid to circulate between the first liquid discharge chamber 130 and the mold shell, and the other drives the cleaning liquid to circulate between the second liquid discharge chamber 140 and the mold shell. The two circulation driving structures 200 drive different cleaning liquids, which not only can achieve the purpose of using two different cleaning liquids to clean the mold shell and improve the cleaning effect of the mold shell, but also can filter, recycle and reuse the two different cleaning liquids to save costs.

[0051] It should be noted that, in the present embodiment, the corresponding cleaning liquid in the first liquid discharge cavity 130 is a mixed liquid of methylene blue and alcohol in a ratio of 1:9, and the corresponding cleaning liquid in the second liquid discharge cavity 140 is pure water. In other embodiments, the specific components of the corresponding cleaning liquid in the first liquid discharge cavity 130 and the specific components of the corresponding cleaning liquid in the second liquid discharge cavity 140 can also be adjusted according to actual needs, and this embodiment does not make specific limitations. When it is necessary to clean the mold shell, first use a cleaning liquid mixed with methylene blue and alcohol in a ratio of 1:9 to clean the mold shell, and after cleaning, pour the cleaning liquid into the first liquid discharge cavity 130, and then use pure water to clean the mold shell, and after cleaning, pour the cleaning liquid into the second liquid discharge cavity 140.

[0052] like Figure 2 and Figure 3 As shown, the circulation drive structure 200 includes a liquid storage tank 210, a circulation drive member 220, a liquid spraying pipe 230 and a connecting pipe 240, wherein one end of the connecting pipe 240 is connected to the liquid outlet of the first liquid discharge chamber 130 or the second liquid discharge chamber 140, and the liquid storage tank 210 is connected to the other end of the connecting pipe 240. The liquid storage tank 210 is used to temporarily store the cleaning liquid discharged along the liquid outlet of the first liquid discharge chamber 130 or the second liquid discharge chamber 140, the input end of the circulation drive member 220 is connected to the liquid storage tank 210, and the output end of the circulation drive member 220 is connected to the liquid spraying pipe 230. The circulation drive member 220 can drive the cleaning liquid in the liquid storage tank 210 to be sprayed into the mold shell along the liquid spraying pipe 230. By using the connecting pipe 240, the liquid storage tank 210 can be connected to the first liquid discharge chamber 130 or the second liquid discharge chamber 140, so that the cleaning liquid discharged after cleaning the mold shell is filtered by the filter structure 300 and then transported to the liquid storage tank 210 along the liquid outlet and the connecting pipe 240, and the input end of the circulation drive member 220 is connected to the liquid storage tank 210, and the output end of the circulation drive member 220 is connected to the spray pipe 230. The circulation drive member 220 is used to inject the cleaning liquid in the liquid storage tank 210 into the mold shell along the spray pipe 230, so as to realize the circulation of the cleaning liquid between the mold shell and the first liquid discharge chamber 130 or the second liquid discharge chamber 140.

[0053] It should be noted that, in this embodiment, the circulation drive member 220 is a circulation pump. The circulation pump has a simple structure, stable output power, and low control difficulty. In other embodiments, the circulation drive member 220 can also be other mechanisms with a circulation drive function, which is not specifically limited in this embodiment.

[0054] In an alternative embodiment, if Figure 3 and Figure 4As shown, a first guiding slope 131 is provided on the inner cavity wall of the first liquid discharge cavity 130 near one end of the liquid outlet. By providing the first guiding slope 131 on the end surface of the first liquid discharge cavity 130 near one end of the liquid outlet, it is possible to facilitate the cleaning liquid in the first liquid discharge cavity 130 to flow into the liquid storage tank 210 along the liquid outlet. It should be noted that, in this embodiment, the liquid outlet is located at the lower end of the first liquid discharge cavity 130, the liquid inlet is located at the upper end of the first liquid discharge cavity 130, and the liquid outlet of the first liquid discharge cavity 130 is provided at the front end of the inner cavity bottom wall of the first liquid discharge cavity 130, so the first guiding slope 131 gradually tilts downward in the process of the inner cavity bottom wall of the first liquid discharge cavity 130 extending from the back to the front, so that the cleaning liquid can flow into the liquid outlet along its own gravity.

[0055] Further, the inclination angle of the first guide slope 131 is 1° to 3°. In this embodiment, the inclination angle of the first guide slope 131 is 2°. In other embodiments, the inclination angle of the first guide slope 131 can also be adjusted arbitrarily within the range of 1° to 3° according to actual needs, and this embodiment does not make specific limitations.

[0056] In addition, the cross-sectional area of ​​the first liquid discharge cavity 130 gradually decreases as it extends from an end close to the liquid inlet toward an end close to the liquid outlet, so that when the cleaning liquid flows from the liquid inlet at the upper end to the liquid outlet at the lower end, the cleaning liquid in the first liquid discharge cavity 130 is gradually gathered together and discharged, further facilitating the discharge of the cleaning liquid from the first liquid discharge cavity 130.

[0057] It can be understood that a second guiding slope is provided on the inner wall of the second liquid discharge cavity 140 near the liquid outlet, and the specific structure and guiding principle of the second guiding slope are the same as those of the first guiding slope 131, and the cross-sectional area of ​​the second liquid discharge cavity 140 gradually decreases from the end near the liquid inlet to the end near the liquid outlet. To ensure the brevity of the text, the specific structure of the second liquid discharge cavity 140 will not be described here.

By providing the pull-out cavity 120 on the side wall of the cleaning chamber 100, the pull-out cavity 120 simultaneously penetrates the first liquid discharge cavity 130 and the second liquid discharge cavity 140, when the filter structure 300 needs to be placed in the first liquid discharge cavity 130 and the second liquid discharge cavity 140, the filter structure 300 can be pushed in along the pull-out cavity 120; when the filter structure 300 needs to be removed from the first liquid discharge cavity 130 and the second liquid discharge cavity 140, the filter structure 300 only needs to be pulled out along the pull-out cavity 120, and the structure is simple and easy to dismantle. It should be noted that, in the present embodiment, the filter structure 300 includes a support frame and a filter net, the filter net is fixed on the support frame, and the support frame can be extended into the drawer cavity 120 and drawn out from the drawer cavity 120 .

[0059] In order to further facilitate the disassembly and assembly of the filter structure 300 and the cleaning chamber 100 , a handle 310 is provided on the filter structure 300 . When the filter structure 300 needs to be disassembled and assembled, the staff can hold the handle 310 , thereby improving the convenience of disassembly and assembly of the filter structure 300 .

[0060] In addition, a plurality of pull-out cavities 120 are provided on the side wall of the cleaning bin 100 at intervals in the up-down direction, each pull-out cavity 120 simultaneously penetrates the first liquid discharge cavity 130 and the second liquid discharge cavity 140, and each pull-out cavity 120 is provided corresponding to a filter structure 300.

By accommodating the cleaning chamber 100 and the liquid storage tank 210 in the housing 400, the protection of the cleaning chamber 100 and the liquid storage tank 210 can be improved, and by providing the observation window 410 directly opposite to the liquid storage tank 210 and the cleaning chamber 100 on the housing 400, the specific volume of the cleaning liquid stored in the liquid storage tank 210 can be easily observed, and the filtered cleaning liquid is prevented from being injected into the liquid storage tank 210 after the cleaning liquid is filled in the liquid storage tank 210, thereby ensuring the normal circulation drive of the cleaning liquid, and facilitating the disassembly and assembly of the filtering structure 300 and the cleaning chamber 100.

[0062] In order to further facilitate observation of the volume of the cleaning liquid in the liquid storage tank 210, the liquid storage tank 210 may be made of a transparent material.

In other embodiments, the liquid storage tank 210 may also be made of PE (polyethylene), PC (Polycarbonate) or other plastic materials, which are not specifically limited in the present embodiment.

[0063] As an alternative, Figure 1 As shown, the mold shell cleaning equipment also includes an ultrasonic vibrator 500, wherein the ultrasonic vibrator 500 is used to increase the rate at which the cleaning liquid penetrates into the mold shell. When cleaning the mold shell, first inject the cleaning liquid mixed with methylene blue and alcohol in a ratio of 1:9 into the mold shell, stop when the liquid level of the cleaning liquid in the mold shell is 5cm to 10cm away from the pouring cup of the mold shell, and then extend the ultrasonic vibrator 500 into the cleaning liquid, adjust the frequency of the ultrasonic vibrator 500 to 28HZ to 35HZ, and stop after vibrating the cleaning liquid for 3min to 5min, so that the cleaning liquid can fully penetrate into the mold shell.
