Technical Field

[0001] This utility model belongs to the field of casting-related technology, specifically relating to a chilling coating device for gravity casting. Background Technology

[0002] A chilling coating application device for gravity casting is a specialized device designed to uniformly and accurately apply chilling coating to the surface of the mold during the gravity casting process. Gravity casting is a common casting process that utilizes the gravity of molten metal to fill the mold cavity and produce various metal castings. Chilling coating plays a crucial role in gravity casting; it accelerates the cooling rate of specific areas of the casting, refines the grain size, and improves the microstructure and properties of the casting, such as increasing its strength, hardness, and wear resistance.

[0003] However, when the paint inside the storage tank is not used for a long time, the different raw materials inside the paint will separate into layers, making it impossible to maintain a uniform mixing state, which will lead to the unbalanced performance of the sprayed paint. Utility Model Content

[0004] The purpose of this invention is to provide a chilled coating device for gravity casting, in order to solve the problem mentioned in the background art that when the coating inside the storage tank is not used for a long time, the different raw materials inside the coating will separate into layers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chilled coating device for gravity casting, comprising a machine body and a handle installed at the lower end of the machine body;

[0006] A trigger is internally connected to the lower outer wall of the fuselage.

[0007] A spray head is fixedly connected to the outer wall of the left end of the machine body;

[0008] A nozzle is provided on the left side of the spray head, and a storage tank is provided on the upper side of the machine body to store paint. A cap is screwed onto the upper side of the storage tank.

[0009] The cap has a fixing head inside the upper outer wall, a handle on the upper side of the fixing head, a stirring rod on the lower side of the handle, and multiple stirring blades are fixedly connected to the circular outer walls of the left and right ends of the stirring rod at equal intervals from top to bottom.

[0010] Preferably, a fixing block is provided inside the upper outer wall of the fixing head to restrict the position of the handle and the stirring rod.

[0011] Preferably, a sealing ring is provided between the fixing block and the fixing head.

[0012] Preferably, a threaded sleeve is screwed onto the left side of the nozzle, and a retaining ring is provided on the left side of the threaded sleeve.

[0013] Preferably, a limiting groove is formed inside the outer wall of the left end of the threaded sleeve, and a limiting block that is inserted into the limiting groove to the right is fixedly connected at the center of the outer wall of the right end of the fixing ring to limit the position of the nozzle.

[0014] Preferably, the limiting block is provided with ball bearings inside to assist the nozzle in rotating.

[0015] Preferably, a spring is provided between the trigger and the grip to provide resistance when the trigger is pulled.

[0016] Preferably, a fixing seat is fixedly connected to the upper outer wall of the machine body to restrict the installation position of the storage tank, and an observation port is embedded in the front circular outer wall of the storage tank to observe the remaining amount of paint in the storage tank.

[0017] Compared with the prior art, this utility model provides a chilling coating device for gravity casting, which has the following beneficial effects:

[0018] By installing a fixed head, handle, stirring rod, and stirring blade, when spraying is required, the paint can be stirred by rotating the handle, which in turn drives the stirring rod and stirring blade through the fixed head.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] This utility model provides, for example Figure 1-4 The illustrated chilled coating device for gravity casting includes a body 1 and a handle 2 mounted on the lower end of the body 1.

[0026] A trigger 4 is connected to the internal transmission of the lower outer wall of the fuselage 1;

[0027] A spray nozzle 7 is fixedly connected to the outer wall of the left side end of the machine body 1;

[0028] A nozzle 5 is provided on the left side of the spray head 7, and a storage tank 8 is provided on the upper side of the machine body 1 to store the paint. A cap 10 is screwed onto the upper side of the storage tank 8. First, open the cap 10 and pour an appropriate amount of chilled paint into the storage tank 8. Place the mold to be coated in a suitable position and place the nozzle 5 against the center position to be coated to ensure that no paint splashing occurs during the spraying process. The operator holds the handle 2, aligns it with the center of the mold, and pulls the trigger 4 to start spraying. The operator controls the pulling force and time of the trigger 4 to adjust the amount of paint sprayed and the spraying speed until the coating thickness is about 0.4 mm and then stops spraying. After the coating of the mold is completed, release the trigger 4 to stop spraying. Then wait for the paint to dry naturally to form a hardened layer. Finally, close the mold and cast.

[0029] A fixing head 17 is installed inside the upper outer wall of the cap 10. A handle 19 is installed on the upper side of the fixing head 17, and a stirring rod 21 is installed on the lower side of the handle 19. Multiple stirring blades 20 are fixedly connected at equal intervals from top to bottom to the circular outer walls of the left and right ends of the stirring rod 21. The operator holds the handle 19 and rotates it at an appropriate speed and force. During the rotation, the stirring blades 20 are observed to ensure that the stirring is uniform until all components of the coating are fully mixed and there is no obvious layering or sedimentation.

[0030] like Figure 3 and Figure 4 As shown, a fixing block 18 is provided inside the upper outer wall of the fixing head 17 to restrict the position of the handle 19 and the stirring rod 21. A sealing ring 16 is provided between the fixing block 18 and the fixing head 17.

[0031] When the handle 19 is in operation, it transmits the rotational power to the stirring rod 21 through the fixing block 18, while ensuring that the entire stirring assembly does not undergo axial or radial displacement, thus guaranteeing the stability and reliability of the stirring operation. During the stirring process, the sealing ring 16 can prevent the paint from leaking out from the gap between the fixing block 18 and the fixing head 17.

[0032] like Figure 2 As shown, a threaded sleeve 6 is screwed onto the left side of the nozzle 7. A retaining ring 12 is provided on the left side of the threaded sleeve 6. A limiting groove 14 is opened inside the outer wall of the left end of the threaded sleeve 6. A limiting block 13 is fixedly connected to the center of the outer wall of the right end of the retaining ring 12, which is inserted into the limiting groove 14 to the right to limit the position of the nozzle 5. A ball bearing 15 is provided inside the limiting block 13 to assist the nozzle 5 in rotating.

[0033] When the nozzle 5 is brought into contact with the neutron position for spraying, the fixed ring 12 and the limiting block 13 can be rotated to drive the ball 15 to rotate inside the limiting groove 14, thereby flexibly adjusting the angle of the nozzle 5. At the same time, after the nozzle 5 is brought into contact with the neutron area, the machine body 1 area can be flexibly rotated to increase the flexibility of operation.

[0034] like Figure 1 As shown, a spring 3 is provided between the trigger 4 and the grip 2 to provide resistance when the trigger 4 is pulled.

[0035] When the operator applies force to pull the trigger 4, the spring 3 is compressed, generating a reverse elastic force, which provides the operator with tactile feedback, allowing the operator to more accurately control the degree to which the trigger 4 is pulled.

[0036] like Figure 1 As shown, a fixed base 11 is fixedly connected to the upper outer wall of the body 1 to limit the installation position of the storage tank 8. An observation port 9 is embedded in the inner circular outer wall of the front end of the storage tank 8 to observe the remaining amount of paint in the storage tank 8.

[0037] The storage tank 8 is installed on the fixed base 11. The shape and size of the fixed base 11 match the storage tank 8 to ensure that the storage tank 8 will not shake or shift after installation. The operator can visually see the liquid level of the paint through the observation port 9 to determine whether there is enough paint to complete the current coating task. When it is found that the paint is insufficient, the operator can prepare to add paint in advance to avoid interrupting the work due to the paint running out during the spraying process, thus improving work efficiency. At the same time, it also helps to rationally arrange the use of paint and avoid waste.

[0038] The implementation principle of this embodiment is as follows: First, open the cap 10 and pour an appropriate amount of chilled coating into the storage tank 8. Place the mold to be coated in a suitable position, and place the nozzle 5 against the neutron to be sprayed, ensuring that no coating splashes occur during the spraying process. The operator holds the handle 2, aligns it with the neutron of the mold, and pulls the trigger 4 to start the spraying. The operator controls the pulling force and time of the trigger 4 to adjust the amount and speed of the coating sprayed, stopping the spraying when the coating thickness is about 0.4 mm. After the mold is coated, release the trigger 4 to stop the spraying. Then, wait for the coating to dry naturally to form a hardened layer. Finally, close the mold and pour the coating. The operator holds the handle 19 and rotates it at an appropriate speed and force. During the rotation, observe the stirring blade 20 in the coating to ensure uniform stirring until all components of the coating are fully mixed without obvious stratification or sedimentation.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
