Description

Technical Field

[0001] The invention relates to the technical field of casting, and in particular to a novel lost foam casting production line and a casting method. Background Art

[0002] Lost foam casting is a new casting method in which paraffin or foam models with similar size and shape to the casting are bonded together into a model cluster, coated with refractory paint and dried, and then buried in dry quartz sand for vibration molding. The model is poured under negative pressure to vaporize the model, and the liquid metal occupies the position of the model. After solidification and cooling, the casting is formed. After the lost foam casting is completed, the casting needs to be taken out from the quartz sand.

[0003] In the prior art, the invention patent with patent application number CN202221848177.3 discloses a separated lost foam casting production line, including a production line body, a bottom plate fixedly connected to the front side of the production line body, a cooling box arranged on the top of the bottom plate, and a cooling mechanism arranged on the top of the cooling box; the cooling mechanism includes a water tank, a water pump and a water-passing plate, the bottom of the water-passing plate is fixedly connected to the top of the cooling box, the bottom of the water tank is fixedly connected to the top of the water-passing plate, and the bottom of the water pump is fixedly connected to the top of the water-passing plate, which to a certain extent reduces the residual heat on the surface of the casting. The quartz sand can be removed and the residual temperature after molding can be cooled down, which is convenient for storing the casting and performing the next processing; but in the specific operation process, since the casting placed on the slide is stationary when entering the cooling box, the water flow sprayed from the water spray hole cannot remove the quartz sand attached to the lower side of the casting and the side where the casting and the slide are in contact, and the lower side of the casting cannot be cooled down, so the residual temperature of the casting after molding is cooled down slowly. The staff still needs to cool down the casting for the second time and clean the quartz sand on the outside of the casting for the second time, which is time-consuming and laborious. Summary of the invention

[0013] Preferably, the water supply assembly comprises a water tank fixedly mounted on the top of the cooling box, a water pump is fixedly mounted on the water tank, and a water outlet end of the water pump is connected to a water pipe connected to a nozzle.

[0014] The invention also discloses a casting method of a novel casting lost foam casting production line, comprising the following steps: S1: Take the molded casting out of the quartz sand and place it on a V-shaped frame on the bottom plate at the front end of the production line body, with the casting against one side of the V-shaped frame; S2: Then the driving motor is controlled to run, the output shaft of the driving motor drives the screw to rotate, and the sleeve threadedly connected to the screw drives the V-shaped frame and the casting on the V-shaped frame to move into the cooling box through the swing assembly; S3: When the sleeve moves along the axial direction of the screw, the driving gear rotates with the screw and meshes with the driven gear on the rotating shaft. The crank shaft at the end of the driven gear drives the collar to rotate.

[0015] Compared with the prior art, the present invention provides a new type of lost foam casting production line and casting method, which has the following beneficial effects: 1. The new lost foam casting production line and casting method of castings use the swing assembly to flip the V-shaped frame to drive the casting to swing back and forth, so that the casting will not always fit the placement surface, so that the spray cooling mechanism can fully cool the casting and efficiently remove the quartz sand on the surface of the casting, thereby improving the cooling effect and removal effect of the casting, thereby improving the casting production efficiency; 2. The new lost foam casting production line and casting method of castings are linked by the conveying mechanism and the swinging assembly, so that when the conveying mechanism drives the casting to move and load the material through the V-shaped frame, the swinging assembly automatically works and drives the casting to swing back and forth by turning the V-shaped frame, so that the above components act as a linkage mechanism with continuous action, so that the various components cooperate and relate to each other to achieve coordinated movement, so that the cooling and cleaning process of the molded casting is more coherent and smooth; 3. The new lost foam casting production line and casting method of castings can buffer and unload the downward pressure of the casting when the V-shaped frame is turned over and drives the casting to move left and right by elastically setting a buffer plate on the V-shaped frame, so as to avoid the casting from violently colliding with the V-shaped frame when turning over, causing damage to the casting or reducing the service life of the V-shaped frame, thereby ensuring the production quality of castings and the service life of the V-shaped frame; 4. The new lost foam casting production line and casting method of castings drives the moving seat to move through the transmission chain, and the moving seat drives the nozzle to move left and right through the telescopic rod.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] Example 1: Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 A novel casting lost foam casting production line includes a production line body 1, a bottom plate 2 is provided at the end of the production line body 1, and further includes: The conveying mechanism is arranged on the bottom plate 2 and is used to convey the V-shaped frame 3 on which the casting is placed. The V-shaped frame 3 is provided with a plurality of grooves 301. The bottom plate 2 is connected to a guide rod 201 which is slidably connected to the V-shaped frame 3 through a support plate. A swing assembly, which is arranged on the conveying mechanism and is used to drive the V-shaped frame 3 to rotate circumferentially around the guide rod 201; A cooling box 4, which is fixed on the bottom plate 2 and has a spray cooling mechanism disposed therein; and A water supply assembly is arranged on the top of the cooling box 4 and is used to provide clean water to the spray cooling mechanism.

[0021] Specifically, the molded casting is taken out from the quartz sand, and the casting is placed on the V-shaped frame 3 on the bottom plate 2 at the front end of the production line body 1, and the casting is close to one side of the V-shaped frame 3. The conveying mechanism and the swinging assembly cooperate with each other, so that when the conveying mechanism drives the casting to move and load the material through the V-shaped frame 3, the swinging assembly automatically works and uses the V-shaped frame 3 to flip and drive the casting to swing back and forth, so that the above components act as a linkage mechanism with continuous action, so that the various components cooperate and relate to each other to achieve coordinated movement. When the casting swings back and forth and flips, it is conducive to loosening the quartz sand attached to the outside, reducing the difficulty of the subsequent spraying and cooling mechanism to impact and drop the quartz sand, and the swinging assembly uses the V-shaped frame 3 to flip and drive the casting to swing back and forth, so that the casting will not always fit the placement surface, so that the spraying and cooling mechanism can fully cool the casting and efficiently remove the quartz sand on the surface of the casting, improve the cooling effect and cleaning effect of the casting, and then improve the casting production efficiency, so that the cooling and cleaning process of the molded casting is continuous and smooth.

[0022] Example 2: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 A new type of lost foam casting production line for castings, based on Example 1, further, the conveying mechanism includes support plates 5 fixedly mounted on both ends of a bottom plate 2, a screw 501 is rotatably connected between the two support plates 5, a driving motor 502 for driving the screw 501 to rotate is fixedly mounted on one of the support plates 5, a sleeve 503 is threadedly connected to the outer side of the screw 501, and the sleeve 503 is movably connected to the V-shaped frame 3 through a swinging assembly.

[0023] Specifically, when the conveying mechanism is working, the driving motor 502 is controlled to run, and the output shaft of the driving motor 502 drives the screw 501 to rotate on the support plate 5. When the screw 501 rotates, the sleeve 503 moves along the axial direction of the screw 501. When the sleeve 503 moves, the V-shaped frame 3 is driven to move through the swing assembly, so that the casting on the V-shaped frame 3 moves to the cooling box 4, and the casting is cooled and the quartz sand is removed.

[0024] Example 3: Reference Figure 3 , Figure 6 , Figure 7 and Figure 8A new type of lost foam casting production line for castings, based on Example 2, further, the swing component includes a side plate 6 fixedly mounted on the sleeve 503, the side plate 6 is rotatably connected to a rotating shaft 601, a driven gear 602 is arranged on the rotating shaft 601, a driving gear 7 meshing with the driven gear 602 is rotatably connected to the sleeve 503, the driving gear 7 is slidably connected to the screw 501, a crank shaft 8 is arranged on the rotating shaft 601, a collar 801 is movably connected to the crank shaft 8, and a connecting rod 802 is arranged between the collar 801 and the V-shaped frame 3.

[0025] Furthermore, a guide bar 701 is fixedly disposed on the inner side wall of the driving gear 7 , and a slide groove 5011 for the guide bar 701 to slide is provided on the screw rod 501 .

[0026] Specifically, when the sleeve 503 moves along the axial direction of the screw 501, it drives the driving gear 7 to move synchronously. When the driving gear 7 moves, it rotates with the screw 501 under the action of the guide bar 701. The screw 501 drives the driving gear 7 to mesh with the driven gear 602 on the rotating shaft 601 for transmission. The crank shaft 8 at the end of the driven gear 602 drives the collar 801 to rotate. The collar 801 drives the V-shaped frame 3 to swing back and forth around the guide rod 201 through the connecting rod 802, so that the casting attached to one side of the V-shaped frame 3 flips and swings back and forth, the outer surface of the casting will not always fit with the V-shaped frame 3, and there will be no flushing dead angle of the spray cooling mechanism, so that the spray cooling mechanism can fully cool the casting and efficiently remove the quartz sand on the surface of the casting, thereby improving the cooling effect and quartz sand removal effect of the casting, thereby improving the casting production efficiency.

[0027] Example 4: Reference Figure 2 , Figure 3 , Figure 6 and Fig. 9 A new type of lost foam casting production line for castings, based on Example 3, further, a buffer plate 9 is rotatably connected to the groove 301 of the V-shaped frame 3 through a first pin shaft, and a first torsion spring for resetting and rotating the buffer plate 9 is sleeved on the first pin shaft.

[0028] Specifically, by elastically arranging the buffer plate 9 on the V-shaped frame 3, when the V-shaped frame 3 is flipped to drive the casting to move left and right, the buffer plate 9 can buffer and unload the downward pressure of the casting when it is flipped, thereby avoiding a violent collision between the casting and the V-shaped frame 3 when it is flipped, causing damage to the casting or the V-shaped frame 3, thereby ensuring the production quality of the casting and the service life of the V-shaped frame 3.

[0029] Example 5: Reference Figure 3 , Fig.10 and Fig.11A novel lost foam casting production line for castings, based on Example 4, further, a spraying cooling mechanism includes an arc seat 10 fixedly arranged in a cooling box 4 through a connecting plate 401, sprockets 11 are rotatably connected to both sides of the arc seat 10, a transmission chain 111 is arranged between the two sprockets 11, a movable seat 12 is fixedly arranged on the transmission chain 111, and the movable seat 12 is movably connected to a telescopic rod 121 through a rotating shaft, an arc plate 13 coaxially arranged with the arc seat 10 is fixedly arranged in the cooling box 4, one end of the telescopic rod 121 away from the movable seat 12 slides on the arc plate 13, and a nozzle 14 connected to a water supply component is arranged at the bottom of the telescopic rod 121.

[0030] Furthermore, a transmission rod 15 is fixedly provided on the sprocket 11 , and synchronous wheels 16 are provided on the transmission rod 15 and the screw rod 501 , and a synchronous belt is provided between the two synchronous wheels 16 .

[0031] Specifically, when the screw 501 rotates, the transmission rod 15 is driven to rotate through the synchronous wheel 16 and the synchronous belt. When the transmission rod 15 rotates, the sprocket 11 is driven to rotate. When the sprocket 11 rotates, the transmission chain 111 is driven to move. The transmission chain 111 drives the movable seat 12 to move along the arc seat 10, so that the movable seat 12 drives the nozzle 14 to move back and forth left and right through the telescopic rod 121, so that the nozzle 14 flushes the casting from left to right and then from right to left. Since the casting swings left and right on the V-shaped frame 3, the water flow sprayed by the nozzle 14 can fully impact the surface of the casting, and the casting will not always fit with the V-shaped frame 3, thereby achieving comprehensive cooling of the casting surface and removal of quartz sand.

[0032] Example 6: Reference Fig.10 , Fig.11 , Fig.12 and Fig.13 A new type of lost foam casting production line for castings, based on Example 5, further, the nozzle 14 is rotatably connected to the bottom of the telescopic rod 121 through a second pin shaft, and the second pin shaft is sleeved with a second torsion spring for driving the nozzle 14 to reset and rotate, and a plurality of baffle rods 131 that resist the movement of the nozzle 14 are fixed on the arc plate 13.

[0033] Specifically, when the telescopic rod 121 moves along the arc seat 10 with the movable seat 12, the nozzle 14 at the bottom of the telescopic rod 121 will intermittently abut against the baffle 131 provided on the arc plate 13, and the side curved surface of the nozzle 14 moves backward when abutting against the curved surface at the end of the baffle 131, and when the nozzle 14 is not abutting against the baffle 131, it returns to its original position and moves forward under the action of the second torsion spring, so that the nozzle 14 swings back and forth relative to the telescopic rod 121, so that the nozzle 14 impacts the quartz sand on the surface of the casting at different angles, which is convenient for loosening the quartz sand tightly adhered to the surface of the casting, ensuring the cleaning effect and efficiency of the quartz sand on the outside of the casting, and improving the production quality and efficiency of the casting.

[0034] Example 7: Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 A new type of lost foam casting production line for castings, based on Example 6, further, a water supply component includes a water tank 17 fixedly mounted on the top of the cooling box 4, a water pump 171 is fixedly mounted on the water tank 17, and a water outlet end of the water pump 171 is connected to a water pipe 172 connected to the nozzle 14.

[0035] Specifically, the water tank 17 is filled with clean water, and the water supply component controls the operation of the water pump 171. The water pump 171 draws clean water from the water tank 17 and supplies water to the nozzle 14 through the water pipe 172 to ensure that the nozzle 14 continues to cool the casting and clean it.

[0036] The invention also discloses a casting method of a novel casting lost foam casting production line, comprising the following steps: S1: Take the molded casting out of the quartz sand and place the casting on a V-shaped frame 3 on the bottom plate 2 at the front end of the production line body 1, with the casting leaning against one side of the V-shaped frame 3; S2: Then the driving motor 502 is controlled to operate, the output shaft of the driving motor 502 drives the screw 501 to rotate, and the sleeve 503 threadedly connected to the screw 501 drives the V-shaped frame 3 and the casting on the V-shaped frame 3 to move into the cooling box 4 through the swing assembly; S3: When the sleeve 503 moves axially along the screw rod 501, the driving gear 7 rotates with the screw rod 501 and meshes with the driven gear 602 on the rotating shaft 601. The crank shaft 8 at the end of the driven gear 602 drives the collar 801 to rotate. The collar 801 drives the V-shaped frame 3 to swing back and forth around the guide rod 201 through the connecting rod 802, so that the casting attached to one side of the V-shaped frame 3 swings back and forth, and the outer surface of the casting will not always fit with the V-shaped frame 3. S4: When the screw 501 rotates, the transmission rod 15 is driven to rotate through the synchronous wheel 16 and the synchronous belt. When the transmission rod 15 rotates, the sprocket 11 is driven to rotate. When the sprocket 11 rotates, the transmission chain 111 is driven to move. The transmission chain 111 drives the moving seat 12 to move along the arc seat 10, so that the moving seat 12 drives the nozzle 14 to move back and forth left and right through the telescopic rod 121, so as to achieve comprehensive cooling of the casting surface and removal of quartz sand. In addition, because the casting swings left and right on the V-shaped frame 3, the water flow sprayed by the nozzle 14 can fully impact the surface of the casting; S5: When the telescopic rod 121 moves along the arc seat 10 with the movable seat 12, the nozzle 14 at the bottom of the telescopic rod 121 intermittently abuts against the blocking rod 131 provided on the arc plate 13, and the nozzle 14 cooperates with the second torsion spring to swing back and forth relative to the telescopic rod 121, so that the nozzle 14 impacts the quartz sand on the surface of the casting at different angles, thereby comprehensively cooling and cleaning the formed casting.

[0037] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

The casting method of the novel casting lost foam casting production line according to claim 9, characterized in that: The following steps are involved: S1: taking out the molded casting from the quartz sand, placing the casting on a V-shaped frame (3) on the front end bottom plate (2) of the production line body (1), with the casting resting against one side of the V-shaped frame (3); S2: Then, the driving motor (502) is controlled to operate, and the output shaft of the driving motor (502) drives the screw (501) to rotate, and the sleeve (503) threadedly connected to the screw (501) drives the V-shaped frame (3) and the casting on the V-shaped frame (3) to move into the cooling box (4) through the swing assembly; S3: When the sleeve (503) moves axially along the screw (501), the driving gear (7) rotates along with the screw (501) and meshes with the driven gear (602) on the rotating shaft (601) for transmission, and the crank shaft (8) at the end of the driven gear (602) drives the collar (801) to rotate. The collar (801) drives the V-shaped frame (3) to swing back and forth around the guide rod (201) through the connecting rod (802), so that the casting abutting against one side of the V-shaped frame (3) swings back and forth, and the outer surface of the casting does not always fit the V-shaped frame (3); S4: When the screw (501) rotates, the transmission rod (15) is driven to rotate through the synchronous wheel (16) and the synchronous belt. When the transmission rod (15) rotates, the sprocket (11) is driven to rotate. When the sprocket (11) rotates, the transmission chain (111) is driven to move. The transmission chain (111) drives the moving seat (12) to move along the arc seat (10), so that the moving seat (12) drives the nozzle (14) to move back and forth left and right through the telescopic rod (121), thereby achieving comprehensive cooling of the casting surface and removal of quartz sand. In addition, because the casting swings left and right on the V-shaped frame (3), the water flow sprayed by the nozzle (14) can fully impact the surface of the casting; S5: When the telescopic rod (121) moves along the arc-shaped seat (10) with the movable seat (12), the nozzle (14) at the bottom of the telescopic rod (121) intermittently abuts against the stop rod (131) provided on the arc-shaped plate (13), and the nozzle (14) cooperates with the second torsion spring to swing back and forth relative to the telescopic rod (121), so that the nozzle (14) impacts the quartz sand on the surface of the casting at different angles, thereby comprehensively cooling and cleaning the formed casting.
