Description

Technical Field

[0001] The present invention belongs to the technical field of casting molding, and specifically relates to a faucet casting molding device and a molding method thereof. Background Art

[0002] The faucet casting molding device mainly refers to the device used to inject molten metal liquid into a mold during the manufacturing process of a faucet, and after cooling and solidification, it forms the components with the required shape. This process usually involves casting processes such as sand casting, permanent mold casting, or gravity casting.

[0003] Sand casting is a basic casting process. The molding sand (a mixture composed of sand grains, binders, and additives) is evenly mixed, then filled into the mold, and appropriate pressure is applied to compact the sand mold. The compacted sand mold will form the external and internal shapes of the faucet. Subsequently, the sand mold is placed in the mold, and finally, the molten metal liquid is poured into the mold.

[0004] For example, in the published patent: CN118950933A, a large-size hexagonal nut casting device vibrates the molding sand to make it fall loosely, and then relies on a filtering structure to screen the used molding sand. The qualified molding sand is conveyed to an adjustable sand filling structure through a feeding structure, and the unqualified molding sand will be discharged from the slag discharge pipe. Therefore, manual sand filling is not required, and the production efficiency of hexagonal nuts is improved.

[0005] As recorded in the above patent, the used molding sand needs to be screened for caked and agglomerated molding sand to solve the problem that the different particle sizes of the sand grains in the molding sand affect the quality of the later casting molding of the molten metal liquid. However, directly discharging the unqualified molding sand without continuing to put it into use is a waste of resources.

[0006] Therefore, the present invention provides a faucet casting molding device and a molding method thereof. Summary of the Invention

The output end of the driving motor is fixedly connected to the first gear. A reciprocating lead screw is fixedly installed at the top end of the first gear. A sliding rod is threadedly connected to the outer wall of the reciprocating lead screw. One end of the sliding rod extends into the piston cylinder and is fixedly connected to the piston.

[0016] A toothed ring is fixedly installed inside the second platform. A second gear meshing with the first gear is rotatably installed inside the first platform. A rotating rod is fixedly installed at the bottom end of the second gear. One end of the rotating rod extends into the second platform and is fixedly installed with a transmission block. Tooth blocks meshing with the toothed ring are fixedly installed on the outer wall of the transmission block.

[0017] A retaining ring is rotatably installed inside the upper box body. The diameter of the retaining ring is larger than that of the third platform. A filtering ring net is arranged between the retaining ring and the third platform.

[0018] An upper grinding ring is fixedly installed on the inner wall of the retaining ring. A lower grinding ring is elastically installed on the outer wall of the third platform. The tops of both the upper grinding ring and the lower grinding ring are inclined.

[0019] The filtering ring net is slidably installed between the third platform and the retaining ring. An annular groove is opened on the inner wall of the retaining ring. A guiding block is fixedly installed on the outer wall of the filtering ring net. One end of the guiding block extends into the annular groove. The annular groove is inclined. A retaining rod is fixedly installed at the bottom end of the filtering ring net. A push rod for pushing the retaining rod is fixedly installed on the inner wall of the retaining ring.

[0020] A forming method of a faucet casting and forming device includes the following steps:

[0021] S1: First, the used molding sand is fed into the material pipe through the feeding pipe, and then the first gear is controlled to rotate by the driving motor, and then the gear ring drives the second platform to rotate through the cooperation of the second gear and the transmission block, thereby controlling the crushing roller to crush the molding sand once;

[0022] S2: Secondly, the second platform will drive the baffle ring to rotate at the same time, and the push rod will drive the baffle rod and the filter ring to rotate. Under the cooperation of the guide block and the annular groove, the filter ring will push the lower grinding ring to slide up until it is aligned with the upper grinding ring.

The tooth block arranged on the outer wall of the transmission block will mesh with the gear ring to form a differential speed, thereby reducing the rotation speed of the second platform and improving the crushing effect of the crushing roller.

[0026] 2. A faucet casting and molding equipment and a molding method thereof described in the present invention drives the retaining ring to rotate through the second platform, and at this time the push rod will push the retaining rod to rotate the filter ring net, and through the cooperation of the guide block and the annular groove, the filter ring net will slide back and forth up and down, and when the filter ring net slides upward, it will drive the blocked molding sand to push the lower grinding ring to slide upward, and when the lower grinding ring is flush with the upper grinding ring, the filter ring net will continue to rotate for a distance before sliding down, so the molding sand on the surface of the filter ring net will be secondary crushed by the friction between the upper grinding ring and the lower grinding ring, and the secondary crushed molding sand will pass through the filter ring net, which is convenient for subsequent use.

[0039] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0040] Example 1: As Figures 1 to 9 shown, a faucet casting and molding device according to an embodiment of the present invention includes an upper box body 1 and a lower box body 2. An inlet pipe 4 is provided at the top of the upper box body 1, and a feeding pipe 3 is provided on one side of the lower box body 2. The other end of the feeding pipe 3 extends above the inlet pipe 4, and a conveying auger is provided inside the feeding pipe 3;

[0041] The top of the lower box body 2 is provided with an opening. After the formed faucet is knocked, the internal molding sand can be knocked out, then enter the interior of the lower box body 2, and finally be sent back into the interior of the feeding pipe 4 again through the conveying auger arranged inside the feeding pipe 3 for recycling.

[0042] A third platform 7 is fixedly installed inside the upper box body 1. The top end of the third platform 7 is rotatably installed with a second platform 6, and the top end of the second platform 6 is rotatably installed with a first platform 5. The bottom end of the feeding pipe 4 is located above the second platform 6 with a gap left.

[0043] The first platform 5, the second platform 6 and the third platform 7 can form a frustum of a cone, and its surface is in an inclined state. Therefore, the molding sand poured into the feeding pipe 4 can roll downwards along the inclined surfaces of the second platform 6 and the third platform 7.

[0044] An elastic retaining net 9 is fixedly installed on the inner wall of the feeding pipe 4. The elastic retaining net 9 is in a horn shape, the diameter of the bottom end of the elastic retaining net 9 is larger than that of the top end, and one end of the elastic retaining net 9 is fixedly connected to the bottom end of the inner wall of the feeding pipe 4.

[0045] The elastic retaining net 9 is composed of two parts. The upper part is in a cylindrical shape and the lower part is in a horn shape. When the molding sand falls downward from the interior of the feeding pipe 4, the larger agglomerated molding sand will be blocked by the lower part of the elastic retaining net 9, and the smaller part will penetrate through the holes of the elastic retaining net 9 and continue to roll downward. At this time, the larger agglomerated molding sand will stay between the elastic retaining net 9 and the feeding pipe 4.

[0046] A crushing roller 20 is rotatably installed on the outer wall of the second platform 6. The crushing roller 20 is located inside the elastic retaining net 9.

[0047] The elastic retaining net 9 is located between the crushing roller 20 and the feeding pipe 4. Therefore, after the elastic retaining net 9 blocks the agglomerated molding sand, the second platform 6 can be rotated at this time to drive the crushing roller 20 to crush the agglomerated molding sand blocked by the elastic retaining net 9, thereby completing the first-stage crushing of the molding sand.

[0048] As a preferred embodiment of the present invention, a transfer rod 11 is arranged above the first platform 5. An air cavity 12 is opened inside the transfer rod 11, and a moving rod 13 is slidably installed inside the air cavity 12. The top end of the moving rod 13 is fixedly connected to the inner wall of the elastic retaining net 9.

[0049] By injecting gas into the interior of the transfer rod 11, as the air pressure increases, it will push the moving rod 13 to slide upward inside the transfer rod 11, thereby driving the elastic blocking net 9 to move upward inside the feed pipe 4. When the elastic blocking net 9 moves upward, the lower part of the elastic blocking net 9 will be lifted upward, and the elastic blocking net 9 will be tightened, thereby pushing the intercepted agglomerated molding sand toward the inner wall of the feed pipe 4, making the agglomerated molding sand close to the inner wall of the feed pipe 4. By tightening the molding sand, it is convenient for the crushing roller 20 to break the agglomerated molding sand.

[0050] As a preferred embodiment of the present invention, a piston cylinder 10 is provided between the transfer rod 11 and the first platform 5. A piston 17 is slidably installed inside the piston cylinder 10. The outer wall of the piston cylinder 10 is provided with a first air pipe 15 and a second air pipe 16. The other end of the first air pipe 15 extends into the interior of the air chamber 12. Check valves are provided on both the first air pipe 15 and the second air pipe 16.

[0051] The other end of the second air pipe 16 extends into the interior of the elastic blocking net 9. The check valve provided on the second air pipe 16 can effectively block the flow of the piston cylinder 10 toward the second air pipe 16, and the check valve provided on the first air pipe 15 can effectively block the flow of the air chamber 12 toward the piston cylinder 10.

[0052] Therefore, when the piston 17 moves downward from top to bottom inside the piston cylinder 10, the gas inside the elastic blocking net 9 can be sucked into the interior of the piston cylinder 10. Then, when controlling the piston 17 to move upward from bottom to top inside the piston cylinder 10, the gas sucked into the piston cylinder 10 can be transported through the first air pipe 15 to the interior of the air chamber 12, thereby increasing the air pressure inside the air chamber 12. At the same time, it is also possible to control the moving rod 13 to drive the elastic blocking net 9 to move upward to assist in the crushing of the agglomerated molding sand.

[0053] As a preferred embodiment of the present invention, the outer wall of the moving rod 13 fits with the inner wall of the air chamber 12. The top of the moving rod 13 is sealed, and exhaust holes 14 are provided on the moving rod 13.

[0054] When the air pressure inside the air chamber 12 gradually increases, it will push the moving rod 13 to move upward until the exhaust holes 14 provided on the moving rod 13 leak out of the air chamber 12. At this time, the air pressure inside the air chamber 12 will quickly be discharged through the exhaust holes 14, and the air pressure inside the air chamber 12 will gradually decrease. At the same time, since the piston 17 reciprocates to slide to deliver air, the air chamber 12 is not continuously filled with air. When the air chamber 12 is no longer filled with air, at this time, the moving rod 13 will slide downward inside the air chamber 12 under the action of gravity and repeat this movement trajectory. When moving upward, the agglomerated molding sand can be tightened, and when sliding downward, the molding sand located above can fall, facilitating the next lifting to tighten the molding sand, thereby improving the efficiency of primary crushing.

[0055] As a preferred embodiment of the present invention, a first gear 23 is rotatably installed inside the first platform 5, a drive motor 29 is arranged inside the third platform 7, the output end of the drive motor 29 is fixedly connected to the first gear 23, a reciprocating lead screw 19 is fixedly installed at the top end of the first gear 23, a slide bar 18 is threadedly connected to the outer wall of the reciprocating lead screw 19, and one end of the slide bar 18 extends into the piston cylinder 10 and is fixedly connected to a piston 17.

[0056] When the drive motor 29 is started, it will drive the first gear 23 to rotate, so that the reciprocating lead screw 19 can be driven to rotate. At this time, the slide bar 18 will slide up and down on the outer wall of the reciprocating lead screw 19, and at the same time, the piston 17 is controlled to reciprocate up and down inside the piston cylinder 10, and the gas is conveyed into the air chamber 12 through the first air pipe 15 and the second air pipe 16, so as to drive the moving rod 13 to drive the elastic retaining net 9 to move upward, tighten the agglomerated molding sand, and facilitate the crushing roller 20 to complete a primary crushing of the agglomerated molding sand.

[0057] As a preferred embodiment of the present invention, a gear ring 28 is fixedly installed inside the second platform 6, a second gear 24 meshing with the first gear 23 is rotatably installed inside the first platform 5, a rotating rod 25 is fixedly installed at the bottom end of the second gear 24, one end of the rotating rod 25 extends into the second platform 6, and a transmission block 26 is fixedly installed, and a tooth block 27 meshing with the gear ring 28 is fixedly installed on the outer wall of the transmission block 26.

[0058] When the first gear 23 rotates, it will drive the meshing second gear 24 to rotate at the same time. Therefore, under the action of the rotating rod 25, the transmission block 26 will be driven to rotate. At this time, the tooth block 27 arranged on the outer wall of the transmission block 26 will mesh with the gear ring 28 and drive the gear ring 28 to rotate a certain distance. Since the number of tooth blocks 27 is small, when the transmission block 26 rotates one circle, the second platform 6 can only rotate a little distance to complete the differential speed. Therefore, the problem that the drive motor 29 rotates too fast, resulting in the second platform 6 driving the crushing roller 20 to rotate too fast and damaging the elastic retaining net 9 can be effectively solved. At the same time, the problem that if the rotation speed is too slow, the air intake inside the air chamber 12 will be too slow, resulting in the slow tightening of the elastic retaining net 9 on the agglomerated molding sand and affecting the crushing effect of the crushing roller 20 can also be solved.

[0059] As a preferred embodiment of the present invention, a retaining ring 8 is rotatably installed inside the upper box body 1, the diameter of the retaining ring 8 is larger than the diameter of the third platform 7, and a filter ring net 31 is arranged between the retaining ring 8 and the third platform 7.

[0060] The molding sand after the first crushing rolls downward along the inclined surfaces of the outer walls of the second platform 6 and the third platform 7, and will fall above the filter ring net 31 for the final filtration. The unqualified molding sand will be retained above the filter ring net 31 for secondary crushing.

[0061] As a preferred embodiment of the present invention, an upper grinding ring 22 is fixedly installed on the inner wall of the retaining ring 8, a lower grinding ring 21 is elastically installed on the outer wall of the third platform 7, and the tops of the upper grinding ring 22 and the lower grinding ring 21 are both inclined.

[0062] The bottom surfaces of the upper grinding ring 22 and the lower grinding ring 21 are both rough surfaces. A positioning block is provided at the top of the lower grinding ring 21. The top of the lower grinding ring 21 is slidably connected to the positioning block through a plug rod, and a return spring is provided between the plug rod and the positioning block. By providing the return spring, the lower grinding ring 21 can always be kept in a separated state from the upper grinding ring 22. When the lower grinding ring 21 slides upward and aligns with the upper grinding ring 22, at this time, the upper grinding ring 22 and the lower grinding ring 21 can block the gap between the third platform 7 and the retaining ring 8, and at this time, the molding sand after the first crushing will remain on the surfaces of the upper grinding ring 22 and the lower grinding ring 21.

[0063] When the upper grinding ring 22 and the lower grinding ring 21 are separated, the inclined surfaces provided on the top surfaces of the upper grinding ring 22 and the lower grinding ring 21 will not block the falling of the molding sand, which is convenient for the subsequent filter ring net 31 to filter the molding sand.

[0064] As a preferred embodiment of the present invention, the filter ring net 31 is slidably installed between the third platform 7 and the retaining ring 8. An annular groove 30 is formed on the inner wall of the retaining ring 8. A guiding block 32 is fixedly installed on the outer wall of the filter ring net 31, and one end of the guiding block 32 extends into the annular groove 30. The annular groove 30 is inclined. A retaining rod 33 is fixedly installed at the bottom end of the filter ring net 31, and a push rod 34 for pushing the retaining rod 33 is fixedly installed on the inner wall of the retaining ring 8.

[0065] The annular groove 30 is arranged to gradually decrease in height. Therefore, when the filter ring net 31 drives the guiding block 32 to slide inside the annular groove 30, at this time, the filter ring net 31 will move up and down between the third platform 7 and the retaining ring 8. When the filter ring net 31 slides upward, it will drive the blocked molding sand to slide synchronously until it pushes the lower grinding ring 21 to slide upward. When the lower grinding ring 21 is flush with the upper grinding ring 22, at this time, the lower grinding ring 21 can no longer slide. Before the filter ring net 31 slides downward, it will continue to rotate for a certain distance. Therefore, the molding sand on the surface of the filter ring net 31 will be secondarily crushed under the friction of the upper grinding ring 22 and the lower grinding ring 21.

[0066] The second platform 6 is connected to the retaining ring 8 through a connecting rod. Therefore, when the second platform 6 rotates, the retaining ring 8 will also rotate synchronously. The rotation of the retaining ring 8 will drive the push rod 34 to rotate. With the cooperation of the retaining rod 33, when the retaining ring 8 rotates, it will drive the filter ring net 31 to rotate.

[0067] As Figure 10 shown, a forming method of a faucet casting forming device, which uses the above-mentioned faucet casting forming device, includes the following steps:

[0068] S1: First, the used molding sand is sent into the feeding pipe 4 through the feeding pipe 3, and then the driving motor 29 is used to control the rotation of the first gear 23. Through the cooperation of the second gear 24 and the transmission block 26, the toothed ring 28 drives the second platform 6 to rotate, so as to control the crushing roller 20 to crush the molding sand for the first time;

[0069] S2: Secondly, the second platform 6 will drive the retaining ring 8 to rotate at the same time. The push rod 34 drives the retaining rod 33 and the filter ring net 31 to rotate. With the cooperation of the guiding block 32 and the annular groove 30, the filter ring net 31 simultaneously pushes the lower grinding ring 21 to slide upward until it aligns with the upper grinding ring 22. At this time, when the filter ring net 31 rotates, it can cooperate with the lower grinding ring 21 and the upper grinding ring 22 to crush the molding sand for the second time;

[0070] S3: Finally, the crushed molding sand can be discharged from the upper box body 1 and used to make the inner cavity mold of the faucet. Then, the molding sand mold is placed in the faucet mold, and the molten metal liquid is poured in and cooled to complete the forming of the faucet.

[0071] Working principle: The recycled molding sand is sent into the inner part of the feeding pipe 4 through the feeding pipe 3, and then the driving motor 29 drives the first gear 23 to rotate, thereby driving the reciprocating lead screw 19 to rotate. At this time, the sliding rod 18 will slide up and down on the outer wall of the reciprocating lead screw 19, and at the same time, the piston 17 is controlled to reciprocate up and down inside the piston cylinder 10, and the gas is transported into the inner part of the air cavity 12 through the cooperation of the first air pipe 15 and the second air pipe 16, so as to make the moving rod 13 drive the elastic retaining net 9 to move upward and tighten the agglomerated molding sand, which is convenient for the crushing roller 20 to complete the first crushing of the agglomerated molding sand. At the same time, the rotation of the first gear 23 will drive the second gear 24 to rotate at the same time. At this time, the tooth block 27 arranged on the outer wall of the transmission block 26 will mesh with the toothed ring 28 and drive the toothed ring 28 to rotate a certain distance, thereby improving the crushing effect of the crushing roller 20.

[0072] When the second platform 6 drives the retaining ring 8 to rotate, the push rod 34 will push the retaining rod 33 at this time, causing the filter ring net 31 to rotate. And with the cooperation of the guiding block 32 and the annular groove 30, the filter ring net 31 will slide up and down reciprocally. When the filter ring net 31 slides upward, it will drive the blocked molding sand to push the lower grinding ring 21 upward together. When the lower grinding ring 21 is flush with the upper grinding ring 22, before the filter ring net 31 slides down at this time, it will continue to rotate a certain distance. Therefore, the molding sand on the surface of the filter ring net 31 will be secondarily crushed under the friction between the upper grinding ring 22 and the lower grinding ring 21. At this time, the secondarily crushed molding sand will pass through the filter ring net 31, facilitating subsequent use.
