Description

Technical Field

[0001] This utility model relates to the field of mold blank surface treatment technology, and in particular to a corrosion-resistant coating mold blank surface treatment device. Background Technology

[0002] Molds are an indispensable key basic process equipment in modern industrial production, and are widely used in many fields such as automobiles, aerospace, electronics, home appliances, and building materials. During use, mold blanks come into contact with various working media. Under certain environmental conditions such as temperature and humidity, these chemicals can easily react with the surface of the mold blank, leading to corrosion. To avoid this, the inner cavity of the mold blank needs to be coated with an anti-corrosion coating.

[0003] Pre-treatment of the mold base surface is crucial before applying the anti-corrosion coating. Existing pre-treatment technologies, such as acid pickling and alkaline washing, can remove impurities like oil and rust from the mold base surface. However, during storage and transportation, a small amount of dust particles inevitably remain on the inner wall of the mold base. These dust particles act as a physical barrier between the mold base surface and the coating layer. The coating cannot directly contact the mold base surface during application, weakening the adhesion between the coating and the mold base. This leads to decreased coating adhesion and the formation of pore channels, accelerating the corrosion process when the mold base surface comes into contact with corrosive media. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a surface treatment device for anti-corrosion coating mold blanks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a surface treatment device for anti-corrosion coating mold blanks, comprising an exhaust fan and a base frame. A conveying mechanism is installed in the middle of the base frame, and a dust removal mechanism, a spraying chamber, and a baking chamber are sequentially installed on the upper side of the base frame. The conveying mechanism passes through the middle of the dust removal mechanism, the spraying chamber, and the baking chamber in sequence. The exhaust fan is fixedly installed on the upper side of the dust removal mechanism. The dust removal mechanism includes a mounting frame, a connecting frame, a dust sweeping assembly, and an adjusting mechanism. The dust sweeping assembly is installed below the adjusting mechanism. The dust sweeping assembly includes a first servo motor, a driving sprocket, a chain, a driven sprocket, a side frame, and a brush roller. The brush roller is rotatably installed inside the side frame. The driven sprocket is fixedly installed at one end of the brush roller. The driven sprocket is connected to the driving sprocket via the chain. The driving sprocket is fixedly installed on the output shaft of the first servo motor.

[0006] Preferably, the first servo motor is fixedly installed on one side of the side frame, and the adjustment mechanism includes a handle, a threaded rod, a side rod, and a connecting frame. The threaded rod is rotatably installed on the upper middle part of the side frame, and the side rod is fixedly installed on both ends of the upper side of the side frame.

[0007] Preferably, the threaded rod is threadedly connected to the middle of the connecting frame, and the side rod is slidably connected to the connecting frame.

[0008] Preferably, the handle is fixedly installed on the upper end of the threaded rod, and the connecting frame is fixedly connected to the connecting bracket.

[0009] Preferably, the connecting bracket is fixedly connected to the lower middle part of the mounting bracket.

[0010] Preferably, the conveying mechanism includes a driven roller, a conveyor belt, a driving roller, and a second servo motor, with the driven roller and the driving roller respectively rotatably mounted at both ends of the base frame.

[0011] Preferably, the conveyor belt is driven to the outer ring surface of the driven roller and the driving roller, and the second servo motor is driven to the driving roller.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the mold blank is fed into the dust removal mechanism by a conveyor belt. The first servo motor injects power into the drive sprocket. Under the traction of the chain, the drive sprocket drives the driven sprocket to rotate. The driven sprocket then drives the brush roller to rotate. The brush roller has long bristles. After the long bristles come into contact with the inner wall of the mold blank, they sweep off the residual dust particles. Under the action of the exhaust fan, the dust particles are discharged outward, ensuring that the inner cavity is clean and preventing dust particles from remaining in the inner cavity. This ensures the bonding force between the anti-corrosion coating and the mold blank, and guarantees its anti-corrosion ability.

[0014] 2. In this utility model, by rotating the handle, the threaded rod is made to rotate spirally in the middle of the connecting frame. The meshing force generated by the rotation causes the threaded rod to move downward and push the side frame. The side rod slides in the connecting frame to ensure that the side frame moves vertically downward, thereby adjusting the height position of the brush roller to match mold blanks of different heights and expanding the applicability of the device.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4As shown, this utility model provides a surface treatment device for anti-corrosion coating mold blanks, including an exhaust fan 1 and a base frame 6. A conveying mechanism 5 is installed in the middle of the base frame 6. A dust removal mechanism 2, a spraying chamber 3, and a baking chamber 4 are sequentially installed on the upper side of the base frame 6. The conveying mechanism 5 passes through the middle of the dust removal mechanism 2, the spraying chamber 3, and the baking chamber 4 in sequence. The exhaust fan 1 is fixedly installed on the upper side of the dust removal mechanism 2. The dust removal mechanism 2 includes a mounting frame 21, a connecting frame 22, a dust sweeping assembly 23, and an adjusting mechanism 24. The dust sweeping assembly 23 is installed below the adjusting mechanism 24 and includes a first servo motor 231, a drive sprocket 232, a chain 233, a driven sprocket 234, a side frame 235, and a brush. The brush roller 236 is rotatably mounted inside the side frame 235. The driven sprocket 234 is fixedly mounted at one end of the brush roller 236. The driven sprocket 234 is connected to the drive sprocket 232 via a chain 233. The drive sprocket 232 is fixedly mounted on the output shaft of the first servo motor 231. The first servo motor 231 is fixedly mounted on one side of the side frame 235. The conveying mechanism 5 includes a driven roller 51, a conveyor belt 52, a drive roller 53, and a second servo motor 54. The driven roller 51 and the drive roller 53 are rotatably mounted at both ends of the base frame 6. The conveyor belt 52 is connected to the outer ring surface of the driven roller 51 and the drive roller 53. The second servo motor 54 is connected to the drive roller 53.

[0023] The specific settings and functions of this embodiment are described below: By controlling the second servo motor 54 to start, the second servo motor 54 drives the active roller 53 to rotate. Under the connection of the driven roller 51, the conveyor belt 52 is driven to rotate in the middle of the base frame 6. The mold blank that needs to be sprayed with anti-corrosion coating is put into the active roller 53. The conveyor belt 52 sends it into the dust removal mechanism 2. The first servo motor 231 is controlled to start. The first servo motor 231 injects power into the active sprocket 232. Under the traction of the chain 233, the active sprocket 232 drives the driven sprocket 234 to rotate. The driven sprocket 234 then drives the brush roller 236 to rotate. The brush roller 236 has long bristles. After the long bristles come into contact with the inner wall of the mold blank, they sweep off the residual dust particles. Under the action of the exhaust fan 1, the dust particles are discharged outward, ensuring that the inner cavity is clean and avoiding dust particles remaining in the inner cavity. This ensures the bonding force between the anti-corrosion coating and the mold blank and guarantees its anti-corrosion ability.

[0024] Example 2: Figure 1 - Figure 4As shown, the adjustment mechanism 24 includes a handle 241, a threaded rod 242, a side rod 243, and a connecting frame 244. The threaded rod 242 is rotatably mounted on the upper middle part of the side frame 235, the side rod 243 is fixedly mounted on both ends of the upper side of the side frame 235, the threaded rod 242 is threadedly connected to the middle part of the connecting frame 244, the side rod 243 is slidably connected to the connecting frame 244, the handle 241 is fixedly mounted on the upper end of the threaded rod 242, the connecting frame 244 is fixedly connected to the connecting frame 22, and the connecting frame 22 is fixedly connected to the lower middle part of the mounting frame 21.

[0025] The overall effect of this embodiment is that by rotating the handle 241, the threaded rod 242 is spirally rotated in the middle of the connecting frame 244. The meshing force generated by the rotation causes the threaded rod 242 to move downward and push the side frame 235. The side rod 243 slides in the connecting frame 244, ensuring that the side frame 235 moves vertically downward. This adjusts the height position of the brush roller 236 to match mold blanks of different heights, thus expanding the applicability of the device.

[0026] The usage and working principle of this device are as follows: First, debug the device by rotating handle 241, causing the threaded rod 242 to rotate spirally in the middle of the connecting frame 244. The meshing force generated by the rotation causes the threaded rod 242 to move downward and push the side frame 235. The side rod 243 slides in the connecting frame 244, ensuring that the side frame 235 moves vertically downward. This adjusts the height of the brush roller 236 to match mold blanks of different heights. After debugging, the dust removal mechanism 2 is enclosed in its outer shell, and the exhaust fan 1 is powered on to exhaust air. Then, the second servo motor 54 is started, driving the active roller 53 to rotate. Under the action of the driven roller 51, the conveyor belt 52 rotates in the middle of the base frame 6, carrying the mold blanks that need to be sprayed with anti-corrosion coating from... The active roller 53 is inserted, and the conveyor belt 52 sends it into the dust removal mechanism 2. The first servo motor 231 is started, and the first servo motor 231 injects power into the active sprocket 232. Under the traction of the chain 233, the active sprocket 232 drives the driven sprocket 234 to rotate. The driven sprocket 234 then drives the brush roller 236 to rotate. The brush roller 236 has long bristles. After the long bristles come into contact with the inner wall of the mold blank, they sweep off the residual dust particles. Under the action of the exhaust fan 1, the dust particles are discharged outward, ensuring that the inner cavity is clean. Under the conveyor belt 52, it enters the spraying chamber 3 for spraying the anti-corrosion coating of the inner cavity of the mold blank. Then it enters the baking chamber 4 for heating and curing, and is output from the driven roller 51 end. This realizes the batch surface treatment and spraying of the mold blank.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
