[0003] The prior art (publication number: CN217797766U) discloses a metal mold cavity cleaning device, which is used to clean the sand or debris remaining in the cavity after the metal mold is opened, including a baffle, a first pipe, and a second pipe; the baffle is used to cover the cavity, thereby forming a cleaning space between the baffle and the cavity.

[0004] The prior art is placed on the top of the mold to be cleaned so as to clean the inside of the mold through the cooperation of the blowing duct and the suction duct on the device. Although the prior art can clean the mold, the prior art is not effective in sucking dust when cleaning the mold with inconsistent top heights because there is a large gap between the bottom and top of the mold with different heights. Therefore, the prior art can only clean the mold with a flat top, resulting in a small scope of use of the prior art.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0030] like Figure 1 and Figure 2 As shown, a metal mold cavity cleaning device includes: a housing 20, the housing 20 is a hollow rectangular box with an open bottom;

[0031] A blowing pipe 21, which is fixedly connected to the top of the housing 20 and is in the shape of a hollow circular tube;

[0032] The suction pipe 22 is fixedly connected to the wall of one side of the outer shell 20. The suction pipe 22 is also in the shape of a hollow circular tube. The suction pipe 22 and the blowing pipe 21 are both connected to the cavity of the outer shell 20. The blowing pipe 22 is connected to the hair dryer. The suction pipe 22 is connected to a suction fan capable of sucking air. The hair dryer and the suction fan are both electrically connected to a power source. This is an existing technology and will not be elaborated here.

[0033] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the adapting structure can adapt to different mold top walls. The adapting structure includes: an inner limit rod 30 and an extension plate 33. The inner limit rod 30 is symmetrically fixedly connected in the cavity of the outer shell 20, and the extension plate 33 is slidably connected between each adjacent inner limit rod 30.

[0034] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the extension plate 33 is a rectangular plate, the inner limit rod 30 is respectively arranged at the four corners of the cavity of the shell 20, and the extension plate 33 is arranged between the adjacent inner limit rods 30 on each wall surface around the cavity of the shell 20. The height of the inner limit rod 30 and the extension plate 33 is consistent with the height of the cavity of the shell 20. The adaptation structure also includes a slide groove 31, a limit groove 32 and a limit block 34. The slide groove 31 is opened on the side wall surface of the inner limit rod 30, and the limit groove 32 is also opened on the side wall surface of the inner limit rod 30. The limit block 34 is symmetrically fixedly connected to the top of the two side walls of the extension plate 33. The relative walls of each adjacent inner limit rod 30 are all provided with a slide groove 31 and a limit groove 32. The two sides of the extension plate 33 can slide simultaneously in the slide groove 31 of the symmetrical wall surface of the inner limit rod 30 The symmetrical limit blocks 34 on the wall of each extension plate 33 can slide in the limit grooves 32 at the corresponding positions. The position of the limit grooves 32 is higher than the slide grooves 31. The adaption structure also includes a dial block 35 and a schematic groove 36. The dial block 35 is fixedly connected to the front wall of the extension plate 33. The schematic grooves 36 respectively penetrate the surrounding walls of the shell 20. The schematic grooves 36 can adapt to the sliding of the dial block 35. The dial block 35 is a rectangular block. The adaption structure also includes a rotation groove 37 and a universal ball 38. A plurality of rotation grooves 37 are evenly arranged on the bottom wall of the extension plate 33. The universal ball 38 is rotatably connected in each rotation groove 37. The rotation groove 37 is a semicircular groove. The universal ball 38 can rotate in the rotation groove 37. The universal ball 38 is spherical.

[0035] When in use, first turn on the power, and align the bottom of the shell 20 with the top groove of the mold to be cleaned. When the bottom of the shell 20 is aligned with the top of the mold, the blower 21 will blow air into the mold, and the dust in the mold will be blown up by the wind blown out by the blower 21, and the suction pipe 22 can suck the dust blown up by the blower 21 into the suction pipe 22 cavity through the suction fan, so that the cleaning of the mold is completed. When it is necessary to clean the mold with different top heights, the extension plate 33 will slide down due to gravity. When the extension plate 33 slides The extension plate 33 can drive the limit block 34 to slide in the limit groove 32, and the shift block 35 can also slide in the schematic groove 36 due to the sliding of the extension plate 33. When the extension plate 33 slides vertically to the top of the mold, it will stop sliding. The four extension plates 33 will stay on the top of the mold in the corresponding direction. At this time, the four extension plates 33 can reduce the gap formed by the height difference. When the extension plate 33 falls to the top of the mold, the universal ball 38 will contact the top of the mold. When the device moves on the top of the mold, the universal ball 38 in contact with the mold will also roll in the rotating groove 37.

[0036] To summarize, by setting up an adaptor structure, the mold cavity can be cleaned even when cleaning molds with different top heights, because the adaptor structure adapts to the height of the mold through four independent and individually slidable extension plates 33, and the four extension plates 33 can form a hollow rectangular cover to cooperate with the suction pipe 22 to suck out the dust blown up by the blowing pipe 21. By setting up a universal ball 38, the device can move more smoothly when it is translated along the top of the mold for cleaning. Therefore, compared with the prior art, the scope of application of this solution is wider.

[0037] like Figure 2 and Figure 3 As shown, a gathering cover 40 is fixedly connected to the cavity of the shell 20. The gathering cover 40 is a rectangular tube with a gradually narrowing opening on the top. The lower half of the blowing pipe 21 is in the cavity of the gathering cover 40. The end of the suction pipe 22 entering the cavity of the shell 20 is connected to the top of the side wall of the gathering cover 40. The bottom of the gathering cover 40 is flush with the bottom of the shell 20. The extension plate 33 can slide vertically in the gap between the outer wall of the gathering cover 40 and the inner wall of the cavity of the shell 20.

[0038] When in use, the bottom of the housing 20 and the top of the mold are aligned, and the bottom of the gathering cover 40 covers the mold at the same time. When the suction pipe 22 absorbs the dust blown by the blowing pipe 21, the dust will gather toward the suction pipe 22 because the top opening of the gathering cover 40 gradually shrinks.

[0039] In summary, by providing the gathering hood 40, the dust can be more efficiently adsorbed, because the special shape of the gathering hood 40 with the upward opening gradually narrows, so that the dust can be gathered and adsorbed uniformly when the suction pipe 22 adsorbs the dust, thereby improving the cleaning speed of the device.

[0040] Working principle: When in use, first turn on the power, and align the bottom of the shell 20 with the top groove of the mold to be cleaned. When the bottom of the shell 20 and the top of the mold are aligned, the blower 21 will blow air into the mold, and the dust in the mold will be blown up by the wind blown out by the blower 21, and the suction pipe 22 can suck the dust blown up by the blower 21 into the suction pipe 22 cavity through the suction fan, so that the cleaning of the mold is completed. When it is necessary to clean the mold with different top heights, the extension plate 33 will slide down due to gravity, and the extension plate 33 will slide when it slides. Sliding in the slide groove 31, the extension plate 33 can drive the limit block 34 to slide in the limit groove 32, and the shift block 35 will also slide in the schematic groove 36 due to the sliding of the extension plate 33. When the extension plate 33 slides vertically to the top of the mold, it will stop sliding. The four extension plates 33 will stay at the top of the mold in the corresponding direction. At this time, the four extension plates 33 can reduce the gap formed by the height difference. When the extension plate 33 falls to the top of the mold, the universal ball 38 will contact the top of the mold. When the device moves on the top of the mold, the universal ball 38 in contact with the mold will also roll in the rotating groove 37.
