Description

Technical Field

[0001] The invention relates to the technical field of rod blank casting, in particular to a rod blank casting device and a process thereof. Background Art

[0002] As an important metal raw material, billets (such as copper bars, aluminum bars, steel bars, etc.) are widely used in machinery manufacturing, electricity, construction, transportation and other fields. In the casting production of metal billets, the common process is to pour the molten metal into the mold cavity to form;

[0003] After searching, a Chinese patent with publication number CN118808574B discloses a cooling device for a continuous casting mold, which relates to the field of non-ferrous metal metal processing technology, including: a graphite mold, a connecting ring fixedly installed on the surface of the graphite mold, and a water inlet fixedly installed on the bottom of the connecting ring; a cooling device, which includes a connecting pipe, a circular pipe, a nozzle, a sealing block, a driving device, a hollow ring, a sealing slide, a connecting rod and an arc plate. Cooling water enters the connecting pipe through the water inlet and then enters the circular pipe from the connecting pipe. The cooling water is then sprayed out through the nozzle to uniformly cool the forgings in the graphite mold. The connecting pipe is fixedly installed on the surface of the water inlet, the circular pipe is fixedly installed on the circumferential surface of the connecting pipe, and the nozzle is fixedly installed on the circumferential surface of the circular pipe to prevent excessive cooling water from being sprayed out, resulting in rapid cooling and thermal stress on the surface of the casting, thereby increasing the risk of wear and damage to the casting.

[0004] In the above technology, although cooling water is transported into the circular tube through the water inlet and connecting pipes, and the cooling water is sprayed out through the nozzles on the circular tube to cool the forgings, the above nozzles are connected to the mold cavity, which makes it easy for the molten metal to flow into the nozzles, thereby easily causing the nozzles to be blocked, and thus making the subsequent cooling effect poor.

[0012] Preferably, the conveying mechanism includes a support frame, a sprocket, a chain and a bearing plate, the top two ends of the support frame are rotatably connected to two sprockets, the two sprockets are engaged with a chain, and a plurality of bearing plates are fixedly connected between the two chains.

[0015] Preferably, the cooling mechanism includes a support rod, an air pump, a sleeve, and a movable tube. The support rod is fixedly connected to the support plate, one end of the support rod is fixedly connected to the sleeve, the bottom of the inner wall of the sleeve is slidably connected to the movable tube, the top of the support rod away from the end of the sleeve is fixedly connected to the air pump, and the output end of the air pump is connected to the sleeve.

[0016] Preferably, both ends of the bottom of the moving tube are rotatably connected to rollers, the rollers are located below the output port of the moving tube, one end of the outer wall of the moving tube is fixedly connected to a second spring, and the second spring is fixedly connected to the sleeve.

[0017] Preferably, the mold includes an upper module and a lower module, a mold cavity is provided in the middle of the lower module, and a feed hole is provided in the middle of the upper module, and the feed hole is communicated with the mold cavity.

[0018] Preferably, the lower module is provided with a cooling cavity around the mold cavity, the upper module is provided with an air inlet adjacent to the feed hole, the air inlet is connected to the cooling cavity, and an exhaust hole is provided at one end of the bottom of the lower module, the exhaust hole is connected to the cooling cavity.

[0019] Preferably, grooves are provided at both ends of the air inlet at the top of the upper module, and inclined surfaces are provided at both ends of the top of the upper module.

[0020] A casting process comprises the following steps:

[0021] S1. Place the mold filled with molten metal on the carrier plate of the conveying mechanism, between the two clamping mechanisms. Then, the conveying mechanism conveys the mold. During this process, the clamping mechanism moves synchronously with the mold. During the movement of the clamping mechanism, the guide wheel contacts and rolls on the guide plate. Under the guidance of the guide plate, the guide wheel moves toward the mold. At the same time, the first spring contracts. When the guide wheel moves, it also drives the clamping block to move toward the mold, allowing the two clamping blocks to clamp the mold tightly, thereby ensuring stability during the conveying process.

[0022] S2. During the mold conveying process, the mold will gradually move to the bottom of the cooling mechanism. During this process, the roller in the cooling mechanism will contact the inclined surface of the upper module and roll along the inclined surface to the top of the upper module. At this time, the moving tube will move into the sleeve, and at the same time, the second spring will contract. When the groove at the top of the upper module moves directly under the roller, the second spring will rebound and push the moving tube and roller downward. At this time, the roller will be in the groove, and the bottom of the moving tube will be connected with the top of the air inlet.

[0023] S3. Use an air pump to deliver low-temperature air, allowing the low-temperature air to flow into the cooling cavity of the lower module through the sleeve, movable tube and air inlet hole, so as to cool the molten metal in the mold cavity and allow the molten metal to be quickly shaped. During this process, excess air in the cooling cavity will be discharged through the exhaust hole;

[0024] S4. The mold is intermittently transported by the conveying mechanism, that is, it stops for a period of time when it is transported to the bottom of the cooling mechanism so that the molten metal can be fully cooled. At the same time, it is convenient for the staff to place the subsequent mold filled with molten metal on the conveying mechanism. After the molten metal inside the mold is cooled by the four sets of cooling mechanisms, it will be cooled and shaped. At this time, the mold is continued to be transported by the conveying mechanism and the clamping mechanism is moved. When the guide wheel in the clamping mechanism is disengaged from the guide plate, the first spring will rebound and drive the clamping plate to move, so that the two clamping plates are away from each other, so that the staff can remove the mold.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The present invention reduces the temperature of the molten metal in the mold through the design of a cooling mechanism, thereby improving the efficiency of cooling and shaping the casting. The air pump delivers low-temperature air, which flows into the air inlet of the upper module through the sleeve and the moving pipe, and then flows into the cooling cavity of the lower module through the air inlet, thereby reducing the temperature of the molten metal in the mold cavity.

[0027] The present invention transports the mold through a conveying mechanism. During the process of transporting the mold, the mold will gradually move to the bottom of the cooling mechanism. During this process, the roller in the cooling mechanism will contact the inclined surface of the upper module and roll along the inclined surface to the top of the upper module. At this time, the moving tube will move into the sleeve, while driving the second spring to contract. When the groove on the top of the upper module moves to just below the roller, the second spring will rebound and push the moving tube and roller downward. At this time, the roller will be in the groove, and the bottom of the moving tube will be connected to the top of the air inlet hole, so that the air pump can subsequently deliver low-temperature air into the mold cavity.

[0028] The present invention clamps the mold metal through the design of a clamping mechanism, thereby ensuring the stability of the mold during the transportation process. During the movement of the clamping mechanism, the guide wheel will contact the guide plate and roll on the guide plate. Under the guidance of the guide plate, the guide wheel will move toward the mold, thereby driving the clamping block to move toward the mold, allowing the two clamping blocks to clamp the mold, thereby ensuring stability during the transportation process.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] See also Figure 1-Figure 7 The present invention provides a technical solution: a billet casting device, comprising a mold 1, a conveying mechanism 2, a clamping mechanism 3, a support plate 4, a guide plate 5 and a cooling mechanism 6, wherein the conveying mechanism 2 is used to convey the mold 1, the clamping mechanism 3 is provided with multiple groups and is evenly distributed on the surface of the conveying mechanism 2, the support plate 4 is fixedly connected to both ends of the top of the conveying mechanism 2, the guide plate 5 is fixedly connected to one end of the support plate 4, the cooling mechanism 6 is provided with four groups and is fixedly connected to one end of the support plate 4; the cooling mechanism 6 comprises a support rod 601, an air pump 604, a sleeve 602, and a moving tube 603, the support rod 601 is fixedly connected to the support plate 4, one end of the support rod 601 is fixedly connected to the sleeve 602, and the sleeve 602 A movable tube 603 is slidably connected to the bottom of the inner wall, and an air pump 604 is fixedly connected to the end of the top of the support rod 601 away from the sleeve 602, and the output end of the air pump 604 is connected to the sleeve 602; the mold 1 includes an upper module 101 and a lower module 102, a mold cavity 103 is provided in the middle of the lower module 102, a feed hole 104 is provided in the middle of the upper module 101, and the feed hole 104 is connected to the mold cavity 103, a cooling cavity 105 is provided around the mold cavity 103 of the lower module 102, an air inlet hole 106 is provided at a position adjacent to the feed hole 104 of the upper module 101, and the air inlet hole 106 is connected to the cooling cavity 105, and an exhaust hole 107 is provided at one end of the bottom of the lower module 102, and the exhaust hole 107 is connected to the cooling cavity 105;

[0039] Specifically, during the casting process, the molten metal liquid needs to be injected into the mold 1. During operation, the upper module 101 and the lower module 102 need to be spliced ​​together. At this time, the feed hole 104 is connected to the mold cavity 103, and the air inlet 106 is connected to the cooling cavity 105. At this time, the staff can inject the metal liquid into the mold cavity 103 through the feed hole 104, and then place the mold 1 filled with the metal liquid on the conveying mechanism 2, and between the two clamping mechanisms 3. The mold 1 is clamped by the clamping mechanism 3. During the conveying process, the mold 1 will gradually move to the bottom of the cooling mechanism 6. When the air inlet 106 on the top of the upper module 101 moves to the bottom of the moving tube 603, the air pump 604 will be used to transport low-temperature air, allowing the low-temperature air to flow into the cooling cavity 105 of the lower module 102 through the sleeve 602, the moving tube 603 and the air inlet 106, so as to cool the molten metal in the mold cavity 103 and allow the molten metal to be quickly shaped. During this process, excess air in the cooling cavity 105 will be discharged through the exhaust hole 107.

[0040] like Figure 2 As shown, the conveying mechanism 2 includes a support frame 201, a sprocket 202, a chain 203 and a bearing plate 204. The top two ends of the support frame 201 are rotatably connected to two sprockets 202, the two sprockets 202 are meshed and connected to the chain 203, and a plurality of bearing plates 204 are fixedly connected between the two chains 203;

[0041] Specifically, when the mold 1 needs to be transported, the sprocket 202 and the chain 203 need to be driven to rotate. At this time, one of the sprockets 202 needs to be driven to rotate by a motor, thereby driving the chain 203 and the supporting plate 204 to move, thereby realizing the transportation of the mold 1.

[0042] like Figure 3 As shown, the clamping mechanism 3 includes an L-shaped plate 301, a sliding rod 302, a guide wheel 303, a spring damper 304 and a clamping block 305. The L-shaped plate 301 is fixedly connected to the carrying plate 204. One end of the L-shaped plate 301 is slidably connected to the sliding rod 302, and one end of the sliding rod 302 is rotatably connected to the guide wheel 303. The guide wheel 303 is rollingly connected to the guide plate 5. The end of the sliding rod 302 away from the guide wheel 303 is fixedly connected to the spring damper 304, and one end of the spring damper 304 is fixedly connected to the clamping block 305; the sliding rod 302 is located at one end of the guide wheel 303 and is sleeved with a first spring 306. The first spring 306 is fixedly connected to the sliding rod 302 and the L-shaped plate 301. The clamping block 305 is located at both ends of the sliding rod 302 and is fixedly connected to the guide rod 307. The guide rod 307 is slidably connected to the L-shaped rod.

[0043] Specifically, in the process of conveying the mold 1 by the conveying mechanism 2, the clamping mechanisms 3 at both ends of the mold 1 will move synchronously with the mold 1. During the movement of the clamping mechanism 3, the guide wheel 303 will contact the guide plate 5 and roll on the guide plate 5. Under the guidance of the guide plate 5, the guide wheel 303 will move toward the mold 1. At the same time, the first spring 306 will shrink. When the guide wheel 303 moves, it will also drive the clamping block 305 to move toward the mold 1, so that the two clamping blocks 305 can clamp the mold 1, thereby ensuring stability during the conveying process. When the clamping mechanism 3 passes through the guide plate 5, the guide wheel 303 will disengage from the guide plate 5. At this time, the first spring 306 will rebound and drive the clamping plate to move, so that the two clamping plates are away from each other, so that the staff can remove the mold 1.

[0044] like Figures 4 to 6 As shown, rollers 605 are rotatably connected to both ends of the bottom of the moving tube 603. The rollers 605 are located below the output port of the moving tube 603. A second spring 606 is fixedly connected to one end of the outer wall of the moving tube 603. The second spring 606 is fixedly connected to the sleeve 602. The top of the upper module 101 is provided with grooves 108 at both ends of the air inlet 106. The top of the upper module 101 is provided with inclined surfaces 109 at both ends.

[0045] Specifically, during the process of conveying the mold 1, the mold 1 will gradually move to the bottom of the cooling mechanism 6. During this process, the roller 605 in the cooling mechanism 6 will contact the inclined surface 109 of the upper module 101 and roll along the inclined surface 109 to the top of the upper module 101. At this time, the moving tube 603 will move into the sleeve 602, while driving the second spring 606 to contract. When the groove 108 at the top of the upper module 101 moves to directly below the roller 605, the second spring 606 will rebound and push the moving tube 603 and the roller 605 to move downward. At this time, the roller 605 will be in the groove 108, and the bottom of the moving tube 603 will be just docked with the top of the air inlet 106, so that the air pump 604 can transport low-temperature air to the air inlet 106 and the cooling chamber 105.

[0046] A casting process comprises the following steps:

[0047] S1. Place the mold 1 filled with molten metal on the carrier plate 204 of the conveying mechanism 2 and between the two clamping mechanisms 3. Then, the conveying mechanism 2 conveys the mold 1. During this process, the clamping mechanism 3 moves synchronously with the mold 1. During the movement of the clamping mechanism 3, the guide wheel 303 contacts the guide plate 5 and rolls on the guide plate 5. Under the guidance of the guide plate 5, the guide wheel 303 moves toward the mold 1. At the same time, the first spring 306 contracts. When the guide wheel 303 moves, it also drives the clamping block 305 to move toward the mold 1, so that the two clamping blocks 305 can clamp the mold 1, thereby ensuring stability during the conveying process.

[0048] S2. During the conveying process of the mold 1, the mold 1 will gradually move to the bottom of the cooling mechanism 6. During this process, the roller 605 in the cooling mechanism 6 will contact the inclined surface 109 of the upper module 101 and roll along the inclined surface 109 to the top of the upper module 101. At this time, the moving tube 603 will move into the sleeve 602, and at the same time drive the second spring 606 to contract. When the groove 108 on the top of the upper module 101 moves to just below the roller 605, the second spring 606 will rebound and push the moving tube 603 and the roller 605 downward. At this time, the roller 605 will be in the groove 108, and the bottom of the moving tube 603 will be just connected with the top of the air inlet 106.

[0049] S3. Low-temperature air is delivered by the air pump 604 and flows into the cooling cavity 105 of the lower die block 102 through the sleeve 602, the movable tube 603 and the air inlet 106, thereby cooling the molten metal in the die cavity 103 and allowing the molten metal to be quickly shaped. During this process, excess air in the cooling cavity 105 is discharged through the exhaust hole 107.

[0050] S4. The mold 1 is intermittently transported by the conveying mechanism 2, that is, it is kept stationary for a period of time when it is transported to the bottom of the cooling mechanism 6 so that the molten metal can be fully cooled. At the same time, it is convenient for the staff to place the subsequent mold 1 filled with molten metal on the conveying mechanism 2. After the molten metal inside the mold 1 is cooled by the four groups of cooling mechanisms 6, it will be cooled and shaped. At this time, the mold 1 and the clamping mechanism 3 continue to be transported by the conveying mechanism 2. When the guide wheel 303 in the clamping mechanism 3 is disengaged from the guide plate 5, the first spring 306 will rebound and drive the clamping plate to move, so that the two clamping plates are away from each other, so that the staff can remove the mold 1.

[0051] Working principle: During the casting process, the molten metal liquid needs to be injected into the mold cavity 103 through the feed hole 104, and then the mold 1 filled with the metal liquid is placed on the conveying mechanism 2 and located between the two clamping blocks 305. Then, one of the sprockets 202 is driven by the motor to rotate, thereby driving the chain 203 and the carrying plate 204 to move, so as to realize the conveying of the mold 1. In the process of the conveying mechanism 2 conveying the mold 1, the clamping mechanisms 3 at both ends of the mold 1 will move synchronously with the mold 1. During the movement of the clamping mechanism 3, the guide wheel 303 will contact the guide plate 5 and roll on the guide plate 5. Under the guidance of the guide plate 5, the guide wheel 303 will move toward the mold 1, and the first spring 306 will contract. When the guide wheel 303 moves, it will also drive the clamping block 305 to move toward the mold 1, so that the two clamping blocks 305 can clamp the mold 1, thereby ensuring stability during the conveying process.

[0052] During the process of conveying the mold 1, the mold 1 will gradually move to the bottom of the cooling mechanism 6. During this process, the roller 605 in the cooling mechanism 6 will contact the inclined surface 109 of the upper module 101 and roll along the inclined surface 109 to the top of the upper module 101. At this time, the moving tube 603 will move into the sleeve 602, and at the same time drive the second spring 606 to contract. When the groove 108 on the top of the upper module 1 moves to just below the roller 605, the second spring 606 will rebound and push the moving tube 603 and the roller 605 to move to the bottom of the upper module 101. The wheel 605 moves downward. At this time, the wheel 605 is located in the groove 108, and the bottom of the movable tube 603 is connected to the top of the air inlet 106. At this time, the air pump 604 delivers low-temperature air, allowing the low-temperature air to flow into the cooling chamber 105 of the lower module 102 through the sleeve 602, the movable tube 603 and the air inlet 106, thereby cooling the molten metal in the mold cavity 103 and allowing the molten metal to be quickly shaped. During this process, excess air in the cooling chamber 105 is discharged through the exhaust hole 107.

[0053] The mold 1 is intermittently transported by the conveying mechanism 2, that is, it stops for a period of time when it is transported to the bottom of the cooling mechanism 6 so that the molten metal can be fully cooled. At the same time, it is convenient for the staff to place the subsequent mold 1 filled with molten metal on the conveying mechanism 2. After the molten metal inside the mold 1 is cooled by the four groups of cooling mechanisms 6, it will be cooled and shaped. At this time, the mold 1 and the clamping mechanism 3 continue to be transported by the conveying mechanism 2. When the guide wheel 303 in the clamping mechanism 3 is disengaged from the guide plate 5, the first spring 306 will rebound and drive the splint to move, so that the two splints are away from each other, so that the staff can remove the mold 1.

9. The rod casting device according to claim 8, characterized in that: The top of the upper module (101) is provided with grooves (108) at both ends of the air inlet (106), and the top of the upper module (101) is provided with inclined surfaces (109) at both ends.

10. A casting process based on the rod casting device according to claim 9, characterized in that: The following steps are involved: S1. Place the mold (1) filled with molten metal on the carrier plate (204) in the conveying mechanism (2) and between the two clamping mechanisms (3). Then, the mold (1) is conveyed by the conveying mechanism (2). During this process, the clamping mechanism (3) moves synchronously with the mold (1). During the movement of the clamping mechanism (3), the guide wheel (303) contacts the guide plate (5) and rolls on the guide plate (5). Under the guidance of the guide plate (5), the guide wheel (303) moves toward the mold (1). At the same time, the first spring (306) contracts. When the guide wheel (303) moves, it drives the clamping block (305) to move toward the mold (1), so that the two clamping blocks (305) can clamp the mold (1) to ensure stability during the conveying process. S2. During the process of conveying the mold (1), the mold (1) will gradually move to the bottom of the cooling mechanism (6). During this process, the roller (605) in the cooling mechanism (6) will contact the inclined surface (109) of the upper module (101) and roll along the inclined surface (109) to the top of the upper module (101). At this time, the moving tube (603) will move into the sleeve (602) and drive the second spring (606) to contract. When the groove (108) on the top of the upper module (101) moves to just below the roller (605), the second spring (606) will rebound and push the moving tube (603) and the roller (605) to move downward. At this time, the roller (605) will be in the groove (108), and the bottom of the moving tube (603) will be just docked with the top of the air inlet (106); S3, delivering low-temperature air through the air pump (604), allowing the low-temperature air to flow into the cooling cavity (105) of the lower module (102) through the sleeve (602), the movable tube (603) and the air inlet (106), thereby cooling the molten metal in the mold cavity (103) so that the molten metal can be quickly shaped. During this process, excess air in the cooling cavity (105) is discharged through the exhaust hole (107); S4. The mold (1) is intermittently transported by the conveying mechanism (2), that is, it is stopped for a period of time when it is transported to the bottom of the cooling mechanism (6) so that the molten metal can be fully cooled. At the same time, it is convenient for the staff to place the subsequent mold (1) filled with molten metal on the conveying mechanism (2). After the molten metal inside the mold (1) is cooled by the four groups of cooling mechanisms (6), it will be cooled and shaped. At this time, the mold (1) and the clamping mechanism (3) are continued to be transported by the conveying mechanism (2). When the guide wheel (303) in the clamping mechanism (3) is separated from the guide plate (5), the first spring (306) will rebound and drive the clamping plate to move, so that the two clamping plates are away from each other, so that the staff can remove the mold (1).
