Description

Technical Field

[0001] This invention belongs to the field of mold cleaning technology, specifically referring to a mold cleaning device for aluminum alloy casting. Background Technology

[0002] In the aluminum alloy casting process, the casting mold is the core production component. During casting, a large amount of residue and other impurities are easily generated inside the casting mold, and some may even adhere to the mold surface, affecting the quality of the cast product and the service life of the casting mold. Therefore, it is necessary to clean and maintain it frequently. Moreover, aluminum ingot molds are made of steel, making them relatively heavy and inconvenient to handle and clean.

[0003] However, the existing cleaning methods usually involve manual scrubbing with steel brushes and cleaning agents. Traditional cleaning methods not only fail to completely remove impurities from the mold, affecting the quality of the castings, but also, manual cleaning is prone to uneven force, which can scratch the inner wall of the mold during the cleaning process, damaging the mold and affecting its service life. In addition, manual cleaning requires hands to be inserted into the mold, which can easily lead to safety accidents. Furthermore, the wastewater and impurities generated during the cleaning process can easily pollute the surrounding environment. Summary of the Invention

[0074] like Figure 1 As shown, the specific working principle is as follows:

[0075] First, push the push-pull frame 32 to move the cleaning device next to the mold to be cleaned. Then, turn on the lifting motor 44, the rotating motor 49 and the adjusting motor 52 through the controller 54 to adjust the height and angle of the combined cleaning device 4 in sequence so that the combined cleaning device 4 is located directly above or directly below the mold to be cleaned.

[0076] Then, the height of the combined cleaning device 4 is finely adjusted again by the height adjustment device 3. Then, the control cylinder 29 is turned on, so that the control cylinder 29 extends and the protective ring 27 retracts and sticks tightly to the side of the mold to be cleaned. Then, the switching motor 24 is turned on, and the dry ice descaling nozzle 21 is adjusted to a vertical state. Then, the lifting cylinder 18 is turned on, and the lifting cylinder 18 extends, so that the dry ice descaling nozzle 21 extends out of the through hole 17. The dry ice descaling machine 33 is turned on, and granular dry ice is sprayed onto the mold through the dry ice descaling nozzle 21. Under the impact of the dry ice particles, the residue deposits attached to the mold can be removed. Then, the first shifting motor 11 and the second shifting motor 15 are turned on, so that the moving box 16 drives the dry ice descaling nozzle 21 to move above the mold without dead angles to remove slag, ensuring the slag removal effect.

[0077] Then rotate the switching lever 20 to switch the dry ice descaling spray pipe 21 to the rinsing spray pipe 22, turn on the water pump 35, the first shift motor 11 and the second shift motor 15, and spray the cleaning fluid onto the mold to dissolve impurities and dust. During this process, because the protective ring 27 seals the mold, the cleaning fluid and dry ice particles cannot flow out, ensuring that the environment is not polluted during the cleaning process.

[0078] Then switch the cleaning nozzle 23, turn on the impurity removal pump 9, and turn on the air compressor pump 36 and the gas heater 37 so that the heated high-pressure air is sprayed out from the through hole on the protective ring 27 to vaporize the residual moisture. The water vapor and various impurities that have been cleaned are sucked out into the debris box 38 through the cleaning nozzle 23 until the mold is completely clean and dry, thus completing the mold cleaning operation.

[0079] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
