Description

Technical Field

[0001] The invention belongs to the technical field of casting and molding, in particular to a faucet casting and molding equipment and a molding method thereof. Background Art

[0002] Faucet casting equipment mainly refers to the equipment used to inject molten metal into the mold during the faucet manufacturing process, and then form the parts of the desired shape after cooling and solidification. This process usually involves casting processes such as sand casting, metal mold casting or gravity casting.

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

[0004] For example, the patent disclosed: CN118950933A is a large-size hexagonal nut casting equipment, which vibrates the molding sand to make it loose and fall, and then relies on a filtering structure to screen the used molding sand. The qualified molding sand is transported to the adjustable sand filling structure through the feeding structure, and the unqualified molding sand will be discharged from the slag discharge pipe. Therefore, there is no need for manual sand filling, which improves the production efficiency of hexagonal nuts.

[0005] The above patent states that the used molding sand needs to be screened to remove the agglomerated molding sand, so as to solve the problem that the sand particles in the molding sand are of different sizes, which affects the quality of the subsequent molten metal casting.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0024] Embodiment 1: Figures 1 to 9 As shown, a faucet casting and molding device according to an embodiment of the present invention comprises an upper box body 1 and a lower box body 2, wherein a feed pipe 4 is arranged on the top of the upper box body 1, a feed pipe 3 is arranged on one side of the lower box body 2, the other end of the feed pipe 3 extends to the top of the feed pipe 4, and a conveying auger is arranged inside the feed pipe 3; An opening is provided on the top of the lower box body 2. The molding sand inside can be knocked out by knocking on the formed faucet, and then enters the interior of the lower box body 2, and finally is sent back to the interior of the feed pipe 4 through the conveying auger provided inside the feed pipe 3 for recycling.

[0025] A third platform 7 is fixedly installed inside the upper box 1, a second platform 6 is rotatably installed on the top of the third platform 7, a first platform 5 is rotatably installed on the top of the second platform 6, and the bottom end of the feed pipe 4 is located above the second platform 6 with a gap; The first platform 5 , the second platform 6 and the third platform 7 can form a truncated cone, the surface of which is in an inclined state, so that the molding sand poured into the material pipe 4 can roll down through the inclined surfaces of the second platform 6 and the third platform 7 .

[0026] An elastic screen 9 is fixedly installed on the inner wall of the feed pipe 4. The elastic screen 9 is trumpet-shaped. The bottom diameter of the elastic screen 9 is larger than the top diameter. One end of the elastic screen 9 is fixedly connected to the bottom end of the inner wall of the feed pipe 4. The elastic blocking net 9 is composed of two parts, the upper part is cylindrical and the lower part is trumpet-shaped. When the molding sand falls downward from the inside of the feed pipe 4, the larger agglomerated molding sand will be blocked by the lower part of the elastic blocking net 9, and the smaller part will penetrate the holes of the elastic blocking net 9 and continue to roll downward. At this time, the larger agglomerated molding sand will be retained between the elastic blocking net 9 and the feed pipe 4.

[0027] A crushing roller 20 is rotatably mounted on the outer wall of the second platform 6 , and the crushing roller 20 is located inside the elastic blocking net 9 .

[0028] The elastic screen 9 is located between the crushing roller 20 and the feed pipe 4. Therefore, when the elastic screen 9 blocks the agglomerated molding sand, the crushing roller 20 can be driven by rotating the second platform 6 to crush the agglomerated molding sand blocked by the elastic screen 9, thereby completing the first stage of crushing the molding sand.

[0029] 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, a moving rod 13 is slidably installed inside the air cavity 12, and the top of the moving rod 13 is fixedly connected to the inner wall of the elastic blocking net 9.

[0030] By injecting gas toward the interior of the transfer rod 11, as the air pressure increases, the moving rod 13 will be pushed to slide upward inside the transfer rod 11, thereby driving the elastic screen 9 to move upward inside the feed pipe 4. When the elastic screen 9 moves upward, the lower part of the elastic screen 9 will be pulled upward and the elastic screen 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 crush the agglomerated molding sand.

[0031] As a preferred embodiment of the present invention, a piston cylinder 10 is arranged between the transfer rod 11 and the first platform 5, and 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 to the interior of the air cavity 12, and a one-way valve is provided on the first air pipe 15 and the second air pipe 16.

[0032] The other end of the second air pipe 16 extends to the interior of the elastic barrier 9. The one-way valve arranged on the second air pipe 16 can effectively block the flow of the piston cylinder 10 toward the second air pipe 16. The one-way valve arranged on the first air pipe 15 can effectively block the flow of the air cavity 12 toward the piston cylinder 10.

[0033] Therefore, when the piston 17 moves from top to bottom inside the piston cylinder 10, the gas in the elastic screen 9 can be sucked into the piston cylinder 10. When the piston 17 is controlled to move from bottom to top inside the piston cylinder 10, the gas sucked into the piston cylinder 10 can be transported to the inside of the air cavity 12 through the first air pipe 15, thereby increasing the air pressure in the air cavity 12. At the same time, the moving rod 13 can also be controlled to drive the elastic screen 9 to move upward, thereby assisting in breaking up the agglomerated molding sand.

[0034] As a preferred embodiment of the present invention, the outer wall of the moving rod 13 is in contact with the inner wall of the air cavity 12 , the top of the moving rod 13 is sealed, and an exhaust hole 14 is provided on the moving rod 13 .

[0035] When the air pressure in the air cavity 12 gradually increases, it will push the moving rod 13 to move upward until the exhaust hole 14 opened on the moving rod 13 leaks out from the air cavity 12. At this time, the air pressure in the air cavity 12 will be quickly discharged through the exhaust hole 14, and the air pressure in the air cavity 12 will gradually decrease. At the same time, since the piston 17 slides back and forth to realize air supply, the air cavity 12 is not continuously inhaled. When the air cavity 12 no longer inhales air, the moving rod 13 will slide downward inside the air cavity 12 under the action of gravity and repeat this moving trajectory. When pulling upward, the agglomerated molding sand can be tightened. When sliding down, the molding sand located above can be dropped, which is convenient for the next pulling to tighten the molding sand, thereby improving the efficiency of one-time crushing.

[0036] 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 provided inside the third platform 7, the output end of the drive motor 29 is fixedly connected to the first gear 23, a reciprocating screw 19 is fixedly installed on the top of the first gear 23, the outer wall of the reciprocating screw 19 is threadedly connected to a sliding rod 18, one end of the sliding rod 18 extends to the interior of the piston cylinder 10 and is fixedly connected to the piston 17.

[0037] When the driving motor 29 is started, it will drive the first gear 23 to rotate, and thus the reciprocating screw 19 to rotate. At this time, the sliding rod 18 will slide up and down on the outer wall of the reciprocating screw 19, and at the same time control the piston 17 to slide back and forth inside the piston cylinder 10, and cooperate with the first air pipe 15 and the second air pipe 16 to transport gas to the inside of the air cavity 12, so as to enable the moving rod 13 to drive the elastic blocking net 9 to move upward, tighten the agglomerated molding sand, and facilitate the crushing roller 20 to complete one-time crushing of the agglomerated molding sand.

[0038] 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 to the interior of the second platform 6 and is fixedly installed with a transmission block 26, and a gear block 27 meshing with the gear ring 28 is fixedly installed on the outer wall of the transmission block 26.

[0039] 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 set 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 certain distance to complete the differential speed. Therefore, it can effectively solve the problem that the driving motor 29 rotates at a high speed, causing the second platform 6 to drive the crushing roller 20 to rotate too fast and cause damage to the elastic fence 9. At the same time, it can also solve the problem that if the rotation speed is too slow, the air intake inside the air cavity 12 will be too slow, causing the elastic fence 9 to tighten and agglomerate the molding sand slowly, affecting the crushing effect of the crushing roller 20.

[0040] 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 provided between the retaining ring 8 and the third platform 7 .

[0041] The mold sand after the primary crushing rolls down through the inclined surfaces of the outer walls of the second platform 6 and the third platform 7, and falls on the top of the filter ring net 31 for the final filtration, and the unqualified mold sand will be retained on the top of the filter ring net 31 for secondary crushing.

[0042] As a preferred embodiment of the present invention, an upper grinding ring 22 is fixedly mounted on the inner wall of the retaining ring 8, and a lower grinding ring 21 is elastically mounted on the outer wall of the third platform 7. The top ends of the upper grinding ring 22 and the lower grinding ring 21 are both inclined.

[0043] The bottom surfaces of the upper grinding ring 22 and the lower grinding ring 21 are both rough surfaces. A positioning block is provided on the top of the lower grinding ring 21. The top of the lower grinding ring 21 is slidably connected with the positioning block through an insertion rod. A reset spring is provided between the insertion rod and the positioning block. Through the reset spring, the lower grinding ring 21 can always be kept separated from the upper grinding ring 22. When the lower grinding ring 21 slides up and aligns with the upper grinding ring 22, 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. At this time, the once crushed molding sand will remain on the surfaces of the upper grinding ring 22 and the lower grinding ring 21.

[0044] When the upper grinding ring 22 is separated from the lower grinding ring 21 , the inclined surfaces arranged 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, so that the subsequent filtering ring net 31 can filter the molding sand.

[0045] 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, the inner wall of the retaining ring 8 is provided with an annular groove 30, the outer wall of the filter ring net 31 is fixedly installed with a guide block 32, one end of the guide block 32 extends to the inside of the annular groove 30, the annular groove 30 is inclined, the bottom end of the filter ring net 31 is fixedly installed with a retaining rod 33, and the inner wall of the retaining ring 8 is fixedly installed with a push rod 34 for pushing the retaining rod 33.

[0046] The annular groove 30 is gradually lowered from a high position, so when the filter ring net 31 drives the guide block 32 to slide inside the annular groove 30, 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 the lower grinding ring 21 is pushed to slide upward. When the lower grinding ring 21 is flush with the upper grinding ring 22, the lower grinding ring 21 can no longer slide. At this time, the filter ring net 31 will continue to rotate for a distance before sliding down. Therefore, the molding sand on the surface of the filter ring net 31 will be secondary crushed by the friction between the upper grinding ring 22 and the lower grinding ring 21.

[0047] The second platform 6 is connected to the retaining ring 8 through a connecting rod, so 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 31 to rotate.

[0048] like Fig.10 As shown, a molding method of a faucet casting and molding device, the method adopts the above-mentioned faucet casting and molding device, and comprises the following steps: S1: First, the used molding sand is fed into the material pipe 4 through the feeding pipe 3, and then the first gear 23 is controlled to rotate by the driving motor 29, and then the gear ring 28 drives the second platform 6 to rotate through the cooperation of the second gear 24 and the transmission block 26, so as to control the crushing roller 20 to crush the molding sand once; S2: Secondly, the second platform 6 will drive the retaining ring 8 to rotate at the same time, and the push rod 34 will drive the retaining rod 33 and the filter ring net 31 to rotate. Under the cooperation of the guide block 32 and the annular groove 30, the filter ring net 31 will push the lower grinding ring 21 to slide upward until it is aligned 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 perform secondary crushing on the molding sand; S3: Finally, the crushed molding sand can be discharged from the upper box 1 and used to make the inner cavity mold of the faucet. Then the molding sand mold is placed in the faucet mold, and then the molten metal liquid is poured in and cooled to complete the molding of the faucet. Working principle: the recovered molding sand is fed into the interior of the feeding pipe 4 through the feeding pipe 3, and then the first gear 23 is driven to rotate by the driving motor 29, thereby driving the reciprocating screw 19 to rotate. At this time, the sliding rod 18 will slide up and down on the outer wall of the reciprocating screw 19, and at the same time control the piston 17 to slide up and down inside the piston cylinder 10, and cooperate with the first air pipe 15 and the second air pipe 16 to transport gas to the interior of the air cavity 12, so as to enable the moving rod 13 to drive the elastic blocking net 9 to move upward, tighten the agglomerated molding sand, and facilitate the crushing roller 20 to complete a 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 set on the outer wall of the transmission block 26 will engage with the gear ring 28, and drive the gear ring 28 to rotate a certain distance, thereby improving the crushing effect of the crushing roller 20.

[0049] When the retaining ring 8 is driven to rotate by the second platform 6, the push rod 34 will push the retaining rod 33 to rotate the filter ring net 31, and the filter ring net 31 will slide back and forth up and down through the cooperation of the guide block 32 and the annular groove 30. When the filter ring net 31 slides upward, it will drive the blocked molding sand to push the lower grinding ring 21 to slide upward. When the lower grinding ring 21 is flush with the upper grinding ring 22, the filter ring net 31 will continue to rotate for a distance before sliding down. Therefore, the molding sand on the surface of the filter ring net 31 will be secondary crushed by the friction between the upper grinding ring 22 and the lower grinding ring 21. At this time, the secondary crushed molding sand will pass through the filter ring net 31 for subsequent use.
