Description

Technical Field

[0001] This utility model relates to the field of mold rust prevention technology, specifically a mold rust prevention device. Background Technology

[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. During the use of molds, rust can lead to defects such as corrosion pits and cracks on the mold surface, reducing the mold's strength and precision, and shortening its service life. Rust prevention treatment can effectively prevent molds from rusting, extend their service life, and reduce production costs; therefore, rust prevention treatment is essential.

[0003] Utility model patent CN202221118738.4 discloses a high-efficiency spraying device for mold rust prevention. This device includes a housing with openings at the bottom of both sides, each covered by a shielding curtain. A conveyor belt passes through the lower end of the housing, and a rotating structure is located at the top. The rotating structure includes a motor mounted at the top of the housing, with its output shaft connected to a rotating shaft. A first helical gear is mounted at the top of the rotating shaft, meshing with a second helical gear. A rotating rod is located at the bottom of the second helical gear, with a fixed ring fixed to the rod. Multiple rollers are evenly distributed at the bottom of the fixed ring. A fixed ring groove is provided on the top surface of the housing, matching the rollers. An electric push rod is connected to the bottom of the rotating rod, and a spraying structure is located at the lower end of the electric push rod. This high-efficiency spraying device for mold rust prevention, through its spraying and rotating structures, replaces manual brushing with spraying, improving work efficiency. The rotating spraying ensures more even and thorough application of the rust inhibitor, improving the rust prevention effect and enhancing the device's practicality.

[0004] Although the high-efficiency mold rust prevention spray device improves the efficiency of rust prevention treatment for molds, it still has the following shortcomings in actual use: Although the device is equipped with a spray nozzle and spray blades to spray rust prevention onto the mold, because the mold is placed on top of the conveyor belt, the rust inhibitor can only cover the top and surrounding side walls of the mold during spraying, while the bottom area of ​​the mold is difficult to be effectively sprayed. Therefore, the spraying device has significant limitations. In view of this, we propose a mold rust prevention treatment device. Utility Model Content

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. Example 1

[0033] Please see Figures 1-5 As shown, a mold anti-corrosion treatment device includes a base 1. Two first electric cylinders 10 are installed on the inner top of the base 1. A support plate 11 for supporting the mold is fixed between the piston rod ends of the two first electric cylinders 10. A cover 2 is fixed to the top of the base 1. The front end of the cover 2 is open. Two second electric cylinders 21 are fixed to the outer walls of both sides of the cover 2. A connecting plate 22 is fixed between the piston rod ends of the two second electric cylinders 21. A first motor 23 is installed on the outer wall of the connecting plate 22. A clamping plate 24 for holding the mold is coaxially keyed to the output shaft of the first motor 23. A hollow liquid storage tank 3 is installed on the top of the cover 2. A liquid pump 4 is installed on one side, and the inlet of the liquid pump 4 is connected to the liquid storage tank 3. A spraying part 5 is installed inside the opening of the cover 2. The spraying part 5 includes a connecting pipe 50 that is rotatably connected to the outlet of the liquid pump 4. A hollow housing 55 is fixed at the bottom end of the connecting pipe 50. Multiple nozzles 56 for spraying rust inhibitor onto the mold are fixed at the inner wall of the opening of the housing 55. A first pulley 52 is coaxially keyed at the top of the outer wall of the connecting pipe 50. A second pulley 54 is provided on one side of the first pulley 52. ​​A belt 53 is sleeved between the first pulley 52 and the second pulley 54. A second motor 57 for driving the second pulley 54 to rotate is installed on the top of the cover 2.

[0034] Please see Figure 5 As shown, a support plate 26 is bolted to the opening of the cover 2. The connecting pipe 50 passes through the support plate 26 and is rotatably connected to it. Rotating assemblies 51 are provided on both the upper and lower sides of the outer wall of the connecting pipe 50, each comprising a disc 510 coaxially keyed to the connecting pipe 50. Each disc 510 has a mounting groove 5100 on one of its two opposing end faces. Multiple ball bearings 511 are rotatably mounted in the mounting grooves 5100, with the ball bearings 511 on both the upper and lower sides pressing against the support plate 26. Through this arrangement, on the one hand, the support plate 26 provides support for the connecting pipe 50, ensuring the stability of its rotation; on the other hand, the multiple ball bearings 511 ensure the smoothness of the connecting pipe 50's rotation.

[0035] In this embodiment, sealing doors 20 are installed on both the left and right sides of the front end face of the cover 2, and the sealing doors 20 are hinged to the cover 2 via hinges. The sealing doors 20 prevent the rust inhibitor from spreading to the outside during spraying.

[0036] In this embodiment, a filling port 30 is installed on the top of the liquid storage tank 3, and a sealing cap is threaded onto the filling port 30. The filling port 30 facilitates the replenishment of rust inhibitor into the liquid storage tank 3, while the sealing cap ensures the airtightness of the liquid storage tank 3.

[0037] In this embodiment, the base 1 has a U-shaped cross-section and is fixedly connected to the cover 2 by bolts. The U-shaped base 1 provides better support, while the bolt fixing method ensures the reliable connection between the base 1 and the cover 2.

[0038] In this embodiment, the housing 55 has a U-shaped cross-section and is located directly above the support plate 11. The U-shaped design allows multiple spray nozzles 56 to simultaneously spray the top and surrounding sidewalls of the mold.

[0039] In this embodiment, the clamping plate 24 has a circular cross-sectional shape, and the clamping plate 24 and the support plate 11 are located on the same vertical plane. This design facilitates the stable clamping of the mold located on top of the support plate 11 by the clamping plate 24.

[0040] In this embodiment, the liquid storage tank 3 is fixedly connected to the top of the cover 2 by bolts, and the liquid pump 4 is fixedly connected to the top of the cover 2 by bolts. The bolt fixing method ensures the reliable installation of the liquid storage tank 3 and the liquid pump 4, and at the same time, this installation method also has the advantage of easy disassembly and assembly.

[0041] In practical use, the user first places the mold on top of the pallet 11, so that the mold is located in the opening of the housing 55. Then the user turns on the power of the liquid pump 4 and the second motor 57. The liquid pump 4 and the second motor 57 start to work. The rust inhibitor in the storage tank 3 enters the connecting pipe 50 and the housing 55. At the same time, the rust inhibitor is sprayed out through multiple nozzles 56. Meanwhile, the output shaft of the second motor 57 drives the second pulley 54 to rotate. Under the action of the belt 53, the first pulley 52 is driven to rotate. The first pulley 52 drives the connecting pipe 50 and the housing 55 to rotate. At this time, the rust inhibitor is sprayed onto the four walls and top of the mold.

[0042] When the bottom of the mold needs to be sprayed, the operator first turns on the power to the second electric cylinder 21. The piston rod of the second electric cylinder 21 extends and drives the connecting plate 22 to move horizontally. The connecting plate 22 drives the clamping plate 24 to move horizontally. When the clamping plate 24 presses against the two side walls of the mold, the mold is fixed. Then, the operator turns on the power to the first electric cylinder 10. The piston rod of the first electric cylinder 10 drives the support plate 11 to move downward, and the support plate 11 disengages from the mold. Then, the operator turns on the power to the first motor 23. The first motor 23 starts to work. The output shaft of the first motor 23 rotates, driving the clamping plate 24 to rotate. Motor 24 drives the mold to rotate. When the mold rotates 180°, the operator stops the power supply to the first motor 23. At this time, the operator turns on the power supply to the first electric cylinder 10 again. The piston rod of the first electric cylinder 10 drives the support plate 11 to move upward. When the support plate 11 presses against the bottom of the mold, the operator stops the power supply to the first electric cylinder 10. Next, the operator turns on the power supply to the second electric cylinder 21 again. The piston rod of the second electric cylinder 21 extends and drives the connecting plate 22 to move horizontally. The connecting plate 22 drives the clamping plate 24 to move horizontally. The clamping plate 24 then disengages from the mold. Finally, the operator can spray paint the mold again. Example 2

[0043] Please see Figure 6 Based on Example 1, this embodiment provides the following technical solution: anti-slip pads 25 are fixed on the two opposing end faces of the two clamping plates 24. The anti-slip pads 25 are made of rubber.

[0044] The above-mentioned design not only effectively enhances the friction between the clamping plate 24 and the mold, ensuring stability and reliability during operation, but also protects the mold surface thanks to the properties of the rubber material. This design improves work efficiency and avoids mold surface damage that may be caused by excessive friction, thus protecting the mold.
