Description

Technical Field

[0001] The present invention relates to the technical field of equipment and tooling, and in particular to intelligent dipping equipment. Background Art

[0002] With the rise of additive 3D printing technology in the foundry industry, the production capacity and quality of casting sand cores have significantly increased, and the entire industry is moving towards intelligent manufacturing. Before casting, casting sand cores require surface treatment with coatings. This not only reduces sand sticking to the casting, resulting in high-quality surface finishes, but also effectively increases mold rigidity, preventing damage and deformation during handling. To achieve this excellent surface quality, most sand cores are dip-coated, currently the most efficient treatment process suitable for sand cores of varying complexity.

[0003] Currently, almost all intelligent flow coating processes use tools such as carriers or intelligent manipulators to move sand cores to a large dipping tank for dipping. To prevent precipitation in the dipping coating, a circulating diaphragm pump is generally used in conjunction with a dedicated stirring tank. The diaphragm pump is used to pump the coating from the dipping tank to the stirring tank, and then pump it back into the dipping tank after stirring. The main problem with this process is that the diaphragm pump has a limited range of coating that can be pumped out. Some of the coating that is far from the pipe inlet and outlet cannot be sucked into the stirring tank, and the coating inside the coating chamber is prone to stratification and uneven concentration. On the other hand, the high concentration of the coating makes the diaphragm pump and pipeline easily damaged and clogged, resulting in high maintenance costs. As the use time increases, new coating is constantly added, and the new and old coatings mix, which prevents sufficient stirring in the coating chamber and increases the sedimentation of the coating. Summary of the Invention

[0004] Based on this, it is necessary to provide an intelligent dip coating equipment to address the problems of paint precipitation, uneven concentration, and easy damage of the flow coating equipment in the current intelligent flow coating process.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] An embodiment of the present invention discloses an intelligent dipping device, including a dipping pool, a mounting bracket and a first stirring member, wherein the dipping pool is rotatably arranged on the mounting bracket, the first stirring member is connected to the mounting bracket, the first stirring member is in the dipping pool and extends to the bottom of the dipping pool, the first stirring member includes a stirring rod extending from the center of the dipping pool to its side, the stirring rod is provided with a first inclined surface on the side away from the bottom surface of the dipping pool, the first inclined surface extends from the center of the dipping pool to its side, and the first inclined surface is inclined along the first rotation direction of the dipping pool.

[0007] In one embodiment, the stirring rod is further provided with a second inclined surface on the side facing away from the bottom surface of the dipping tank, the second inclined surface extends along the center of the dipping tank toward its side, and the first inclined surface is inclined along the second rotation direction of the dipping tank, and the first rotation direction is opposite to the second rotation direction.

[0008] In one embodiment, a second stirring member is further included, one end of the second stirring member is connected to the stirring rod, and the other end of the second stirring member extends outside the dipping tank along the depth direction of the dipping tank and is connected to the mounting bracket.

[0009] In one embodiment, the end of the stirring rod is close to the side of the dipping tank, and the end of the stirring rod is connected to the second stirring member.

[0010] In one embodiment, a carrying frame is further included, which is arranged on the mounting bracket and is located in the dipping tank. The first stirring member and the carrying frame are spaced apart in sequence at the bottom of the dipping tank toward the opening.

[0011] In one embodiment, the carrying frame is movably disposed in the dipping tank.

[0012] In one embodiment, a guide member is further included, which is rotatably arranged on the mounting bracket. A guide groove is circumferentially arranged on the outer side of the dipping pool, and the guide member is in guiding cooperation with the guide groove.

[0013] In one embodiment, a driving mechanism is further included, wherein the driving mechanism is disposed on the mounting bracket, the driving mechanism is connected to the dipping pool, and the driving mechanism drives the dipping pool to rotate.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figure 1-Figure 3 As shown, embodiments of the present invention disclose an intelligent dipping device for surface treatment of sand cores using a coating. This device not only reduces sand adhesion to the casting, resulting in castings with excellent surface quality, but also effectively improves the rigidity of the mold, preventing damage and deformation during handling. This intelligent dipping device includes a dipping tank 100, a mounting bracket 200, and a first stirring member 300.

[0027] The dipping tank 100 is the main component of the intelligent dipping device and is used to hold the dipping liquid. The dipping tank 100 is rotatably mounted on the mounting bracket 200, allowing the dipping tank 100 to rotate on the mounting bracket 200. Optionally, a rotation axis can be provided at the center of the bottom of the dipping tank 100, and the mounting bracket 200 can be provided with a rotation slot. The dipping tank 100 can be rotatably mounted within the rotation slot via the rotation axis, making it easier to rotate the dipping tank 100.

[0028] The first stirring member 300 is connected to the mounting bracket 200. The first stirring member 300 is located in the dipping tank 100 and extends to the bottom of the dipping tank 100. Please refer to Figure 1 In the above case, part of the mounting bracket 200 can be moved from the outside of the dipping tank 100 to the inside of the dipping tank 100 and connected to the first stirring member 300 at the bottom of the dipping tank 100.

[0029] The first stirring member 300 includes a stirring rod extending from the center of the dipping tank 100 to the side thereof. Optionally, the stirring rod can be composed of Figure 1 The first stirring member 300 is shown as a cross, and the end of each stirring rod extends from the center of the dipping tank 100 to the side thereof to ensure that all positions on the bottom of the dipping tank 100 are covered.

[0030] Furthermore, a first inclined surface 311 is formed on the side of the stirring rod facing away from the bottom surface of the dipping tank 100. The first inclined surface 311 extends from the center of the dipping tank 100 toward its side, and the first inclined surface 311 is inclined along the first rotation direction of the dipping tank 100. In other words, the stirring rod has an upwardly directed first inclined surface 311 along its length, and the upper side of the first inclined surface 311 is inclined toward the first rotation direction of the dipping tank 100.

[0031] Furthermore, it should be noted that, since the first stirring member 300 is connected to the mounting bracket 200 , when the dipping tank 100 rotates, the first stirring member 300 remains stationary.

[0032] From the above content, it can be seen that in the intelligent dipping coating equipment disclosed in the embodiment of the present invention, a first stirring member 300 that remains stationary is provided in the rotatable dipping coating pool 100, and a first inclined surface 311 is provided on the first stirring member 300. Therefore, during the rotation of the dipping coating pool 100, the dipping liquid at the bottom of the dipping coating pool 100 driven by it is blocked by the first inclined surface 311, and the dipping liquid at the bottom of the dipping coating pool 100 moves along the inclined direction of the first inclined surface 311, that is, the dipping liquid at the bottom of the dipping coating pool 100 moves in an oblique upward direction, so that the dipping liquid at the bottom of the dipping coating pool 100 is stirred up by the first stirring member 300, preventing the dipping liquid from precipitating at the bottom of the dipping coating pool 100, thereby better ensuring the uniformity of the dipping liquid, improving the dipping quality of the product, and at the same time, scraping off the sediment at the bottom of the dipping coating pool 100, reducing the equipment itself and subsequent maintenance costs, and generating better economic benefits.

[0033] In the embodiment of the present invention, a second inclined surface 312 may be provided on the side of the stirring rod facing away from the bottom surface of the dipping tank 100. The second inclined surface 312 may extend from the center of the dipping tank 100 to the side thereof, and the first inclined surface 311 may be inclined along the second rotation direction of the dipping tank 100. The first rotation direction may be opposite to the second rotation direction. This method is equivalent to providing an inverted triangle shape in the vertically upward direction of the stirring rod, such as Figure 2 In this case, when the dipping tank 100 is rotating forward, the stationary first inclined surface 311 can stir up the dipping liquid at the bottom of the dipping tank 100 to prevent the dipping liquid from settling at the bottom of the dipping tank 100; when the dipping tank 100 is rotating backward, the stationary second inclined surface 312 can stir up the dipping liquid at the bottom of the dipping tank 100 to prevent the dipping liquid from settling at the bottom of the dipping tank 100, thereby better ensuring the uniformity of the dipping liquid and improving the dipping effect on the product.

[0034] The intelligent dipping device disclosed in the embodiment of the present invention may further include a second stirring member 400, one end of which may be connected to the stirring rod, and the other end of which may extend outside the dipping tank 100 along the depth direction of the dipping tank 100 and be connected to the mounting bracket 200. In this case, the first stirring member 300 is equivalent to being connected to the mounting bracket 200 through the second stirring member 400, and the second stirring member 400 is opposite to the inner side of the dipping tank 100, so that during the rotation of the dipping tank 100, the second stirring member 400 can stir the dipping liquid to better ensure the uniformity of the dipping liquid.

[0035] Furthermore, the second stirring member 400 may also be provided with an inclined surface on the side facing away from the inner side of the dipping tank 100. During the rotation of the dipping tank 100, the inclined surface can guide the dipping liquid on the inner side of the dipping tank 100 to the center of the dipping tank 100, thereby better stirring the dipping liquid to prevent the dipping liquid from settling. At the same time, it can also scrape off the sediment on the side of the dipping tank 100, reducing the equipment itself and subsequent maintenance costs.

[0036] In an optional embodiment, the end of the stirring rod can be close to the side of the dipping tank 100, and the end of the stirring rod can be connected to the second stirring member 400. In this case, the stirring mechanism composed of the first stirring member 300 and the second stirring member 400 is close to the inner cavity edge of the dipping tank 100, so as to play the role of stirring the dipping liquid while ensuring that there is enough dipping space in the dipping tank 100 to facilitate the dipping operation of the workpiece. Of course, the stirring mechanism composed of the first stirring member 300 and the second stirring member 400 is close to the inner cavity edge of the dipping tank 100, which can also play a better scraping role on the inner cavity edge of the dipping tank 100, so as to ensure the cleanliness of the inner cavity of the dipping tank 100, thereby reducing the equipment itself and subsequent maintenance costs.

[0037] The intelligent dipping device disclosed in the embodiment of the present invention may further include a carrying frame 500. The carrying frame 500 may be disposed on the mounting bracket 200 and may be located within the dipping tank 100. The first stirring member 300 and the carrying frame 500 may be spaced apart at the bottom of the dipping tank 100 toward the opening, i.e., the carrying frame 500 is located above the first stirring member 300. In this case, the carrying frame 500 not only supports the workpiece to facilitate dipping and coating, but also supports larger impurities to prevent them from falling to the bottom of the dipping tank 100 and affecting the stirring action of the first stirring member 300 on the dipping liquid.

[0038] In an optional embodiment, the carrier frame 500 is arranged in a liftable manner within the dipping tank 100, thereby facilitating the dipping and removal of workpieces, stirring the dipping liquid to improve the uniformity of the dipping liquid, and facilitating the cleaning of impurities on the carrier frame 500. Of course, there may be various mechanisms for achieving retraction and extension, and the present invention is not limited thereto.

[0039] The intelligent dipping device disclosed in the embodiment of the present invention may further include a guide member 600, which is rotatably mounted on the mounting bracket 200. A guide groove 110 may be provided circumferentially along the outer side of the dipping tank 100, and the guide member 600 may be guided and engaged with the guide groove 110. In this case, the guiding and engaging of the guide member 600 with the guide groove 110 can improve the rotational stability of the dipping tank 100, thereby improving the dipping effect on each workpiece.

[0040] The intelligent dipping device disclosed in the embodiment of the present invention may further include a drive mechanism 700, which may be disposed on the mounting bracket 200 and connected to the dipping pool 100. The drive mechanism 700 may drive the dipping pool 100 to rotate. In this case, the drive mechanism 700 can free up manpower while also achieving stable rotation of the dipping pool 100 to ensure a good dipping effect.

[0041] In an optional embodiment, an annular rack 120 may be provided at the bottom of the dipping tank 100, and the driving end of the driving mechanism 700 may be engaged with the annular rack 120. The driving end of the driving mechanism 700 may be a gear, and the gear may be engaged with the annular rack 120. This driving method has a simple structure and is easy to implement, and can also produce a relatively stable driving effect. In addition, the driving mechanism 700 can be arranged at the bottom of the dipping tank 100, thereby improving the overall layout of the intelligent dipping equipment.

[0042] The intelligent dipping device disclosed in the embodiment of the present invention may further include a temperature control mechanism, the control end of which may be disposed within the first stirring member 300, and the temperature control mechanism may be used to control the temperature of the first stirring member 300. In this case, the temperature of the dipping liquid within the dipping tank 100 is indirectly controlled by controlling the temperature of the first stirring member 300, thereby achieving a better dipping effect on the workpiece.

[0043] Optionally, the first stirring member 300 can be a hollow structural member, and a circulating coolant or high-temperature liquid can be passed into the first stirring member 300 to enable the special medium with temperature requirements in the dipping tank 100 to maintain a constant temperature or increase or decrease the temperature. A heating tube, a resistance wire, etc. can also be made into the structure of the first stirring member 300 to directly achieve heating or temperature control of the medium. The specific temperature control method is not limited in the embodiment of the present invention. Of course, the second stirring member 400 can also be designed as a structural member capable of temperature control, and the specific setting method is also not limited in the embodiment of the present invention.

[0044] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
