Technical Field

[0001] This application relates to the field of parts casting technology, and in particular to a surface coating device for casting molds. Background Technology

[0002] Currently, sand casting is a casting method that produces castings in sand molds. It is widely used in the production of steel, iron, and most non-ferrous alloy castings. In the sand casting process, in order to ensure the quality of the castings and production efficiency, after the mold is manufactured and before pouring the molten metal, a coating needs to be applied to the surface of the mold to protect the molding sand and the core mold.

[0003] In related technologies, when it is necessary to apply paint to a mold, the paint is usually applied to the surface of the mold by hand with a brush. However, this wastes a lot of time and manpower, and is prone to paint waste and uneven application. It is difficult to guarantee the quality and efficiency of spraying, which is very inconvenient.

[0004] To address the aforementioned issues, a surface coating device for casting molds is now designed. Utility Model Content

[0005] This application provides a surface coating device for casting molds to solve the problems in related technologies where manual coating of molds not only wastes a lot of time and manpower, but also easily leads to paint waste and uneven application, making it difficult to guarantee coating quality and efficiency.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] This application provides a surface coating device for casting molds, which solves the problems in related technologies where manual coating of molds not only wastes a lot of time and manpower, but also easily leads to paint waste and uneven application, making it difficult to guarantee coating quality and efficiency.

[0025] Please see Figures 1-3 A surface spraying device for casting molds includes: a workbench 1, a groove 11 at the upper end of the workbench 1, a storage tank 2 on one side of the workbench 1, a discharge pipe 21 at the lower end of one side of the storage tank 2, a first connecting pipe 3 on the discharge pipe 21, a water pump 4 at the end of the first connecting pipe 3 away from the discharge pipe 21, a second connecting pipe 5 on the water pump 4, and a spray nozzle 6 at the end of the second connecting pipe 5 away from the water pump 4.

[0026] In this way, when in use, the staff can use a crane to place the mold in the groove 11 on the workbench 1, then put the paint into the storage tank 2, and then start the water pump 4 to extract the paint from the storage tank 2. The paint flows through the discharge pipe 21, through the first connecting pipe 3, the water pump 4 and the second connecting pipe 5, and finally sprays out through the nozzle 6. The staff can then hold the nozzle 6 and spray the paint onto the surface of the mold, and adjust the position and spraying direction of the nozzle 6 as needed to ensure that the paint is evenly covered on the surface of the mold.

[0027] In this way, the staff only needs to move the nozzle 6 to spray the paint onto the mold surface. This not only makes it easier for the staff to operate and saves a lot of time and manpower, but also makes the mold more evenly and fully coated, thereby ensuring the coating quality and efficiency of the mold. Excess paint will be stored in the groove 11 for easy recycling, thus avoiding paint waste and making it highly practical.

[0028] Specifically, in this embodiment, the workbench 1 is provided with a discharge pipe 12 communicating with the groove 11, the discharge pipe 12 is provided with a feed pipe 7, and the upper end of one side of the storage tank 2 is provided with a feed pipe 22. The feed pipe 22 is connected to the end of the feed pipe 7 away from the discharge pipe 12, and the height of the plane where the discharge pipe 12 is located is higher than the height of the plane where the feed pipe 22 is located.

[0029] In this way, during use, the paint in the groove 11 will flow from the discharge pipe 12 into the discharge pipe 7 under the action of gravity, and finally flow back to the storage tank 2 through the feed pipe 22. This allows excess paint to flow back to the storage tank 2 for recycling, which not only effectively reduces paint waste, but also ensures a clean working environment and facilitates use.

[0030] More specifically, the bottom surface of the groove 11 is inclined, and the distance between the bottom surface of the groove 11 and the ground gradually increases as the distance between the groove 11 and the discharge pipe 12 increases;

[0031] This ensures that excess paint on the bottom surface of the groove 11 can flow smoothly to the discharge pipe 12, thereby further improving the efficiency of paint recycling and avoiding paint accumulation in the groove 11 and causing waste.

[0032] Please see Figure 3 In this embodiment, a stirring assembly 8 is also included. The stirring assembly 8 includes a motor 81, a rotating shaft 82 and a plurality of stirring blades 83. The rotating shaft 82 is rotatably disposed inside the storage tank 2. The motor 81 is disposed at the upper end of the storage tank 2 and connected to the rotating shaft 82. The plurality of stirring blades 83 are disposed on the rotating shaft 82.

[0033] In this way, the motor 81 drives several stirring blades 83 on the rotating shaft 82 to rotate, thereby stirring and mixing the paint in the storage tank 2. This not only avoids sedimentation and stratification of the paint due to long-term standing, but also mixes the returned paint with the newly added paint evenly. This ensures that the paint drawn from the storage tank 2 always maintains a uniform quality, thereby improving the stability of the spraying effect and making it highly practical.

[0034] The stirring blades 83 are inclined, which allows the coating at the bottom layer and the coating at the top layer in the storage tank 2 to be fully stirred and mixed, thereby enhancing the mixing effect of the coating.

[0035] Preferably, a plurality of the stirring blades 83 are evenly distributed in a ring on the rotating shaft 82, which can further improve the stirring efficiency of the coating.

[0036] Please see Figure 2 In this embodiment, a handle 61 extends from one end of the nozzle 6 near the second connecting pipe 5;

[0037] This allows the worker to hold the handle 61 while spraying paint, making it easier to adjust the position and direction of the nozzle 6 during the spraying process, thus facilitating its use.

[0038] Furthermore, a positioning component 9 is provided in the groove 11. The positioning component 9 includes a first fixing frame 91 and a second fixing frame 92. Both the first fixing frame 91 and the second fixing frame 92 are provided in the groove 11. The first fixing frame 91 is V-shaped, and the second fixing frame 92 is inverted V-shaped. The height of the plane where the first fixing frame 91 is located is higher than the height of the plane where the second fixing frame 92 is located. The handle 61 is located in the first fixing frame 91 and the second fixing frame 92.

[0039] During spraying, when the operator needs to temporarily put down the nozzle 6, the handle 61 can be inserted into the first fixing bracket 91 and the second fixing bracket 92. The first fixing bracket 91 and the second fixing bracket 92 fix the handle 61 and tilt the nozzle 6 downward. This not only keeps the handle 61 suspended, preventing it from falling into the groove 11 and causing contamination, but also makes it easier for the operator to pick it up. Furthermore, the tilted handle 61 can prevent paint from flowing from the end of the nozzle 6 to the handle 61, thus ensuring the cleanliness of the handle 61 and making it easy for the operator to pick up and use. It is highly practical.

[0040] Preferably, the workbench 1 is provided with a plurality of baffles 10;

[0041] In this way, when workers are spraying paint, the baffle 10 can shield and protect the work area, thus preventing paint from splashing outside the work area. The splashed paint will drip down the baffle 10 into the groove 11 for recycling. This not only avoids paint splashing outward and causing waste, but also keeps the work environment clean.

[0042] Furthermore, a valve 23 is provided on the discharge pipe 21;

[0043] This allows workers to control the flow rate of the paint by turning valve 23 during operation, thereby adjusting the paint flow rate according to actual needs, which helps to save paint and improve the accuracy of spraying, making it highly practical.
