Description

Technical Field

[0001] This invention relates to the field of mold casting technology, specifically to a mold for continuous metal casting. Background Technology

[0002] Casting is a process in which metal is melted into a liquid that meets certain requirements and poured into a mold. After cooling and solidification, and cleaning, a casting with a predetermined shape, size and properties is obtained. Because the casting blank is almost formed, it can achieve the purpose of eliminating or minimizing machining, thereby reducing costs and reducing production time to a certain extent.

[0003] CN114749623B discloses a centrifugal casting testing device and casting method for casting boilers, belonging to the field of centrifugal casting. The device includes a workbench with supports fixedly connected to its lower corners and a support fixedly connected to its upper center. A mold is rotatably connected to the upper end of the support, and a pressure plate bolted to the upper end of the mold is provided. A first motor is fixedly connected to the lower right side of the workbench, and a shaft is rotatably connected to the left side of the first motor. A power disk is fixedly connected to the left side of the shaft, and the upper part of the power disk extends through... The workbench and support are fitted to the mold. A front baffle is movably connected to the left side of the mold, which can trigger the water cooling mechanism after the molten liquid is fully distributed on the inner wall of the mold. This prevents the molten liquid from solidifying and forming in the first half of the mold due to premature cooling, which would cause the casting to segment after forming. Although this patent solves the above problems, it is still difficult to demold the cast parts. In the existing technology, most molds are demolded by workers. This step increases production costs and reduces production efficiency. Therefore, a mold for continuous metal casting is proposed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a mold for continuous metal casting, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a mold for continuous metal casting, comprising a shell frame, an upper mold disposed inside the shell frame, a lower mold fixedly connected inside the shell frame, a drive screw rotatably connected inside the shell frame, a protective mechanism disposed at the top of the upper mold, an ejection mechanism disposed at the top of the lower mold, a collecting mechanism disposed at the bottom of the shell frame, a limit rod slidably connected to the inner wall of the shell frame, a motor disposed at the top of the drive screw, and the protective mechanism comprising a feed inlet, an air hole, a protective plate, a drive block, a drive wheel, a C-shaped frame, and a limit angle rod. The feed inlet and the air hole are both located on the inner wall of the upper mold. The protective plate is slidably connected to the top of the upper mold, the driving block is fixedly connected to the rear of the protective plate, the driving wheel is rotatably connected to the rear of the driving block, the C-frame is fixedly connected to the top of the upper mold, and the limiting angle rod is fixedly connected to the outer wall of the lower mold. The protective mechanism also includes an inner horizontal plate, guide pillars, short rods, an ejector plate, and a cavity. The inner horizontal plate is slidably connected to the inner wall of the lower mold, the guide pillars are fixedly connected to the top of the inner horizontal plate, the short rods are fixedly connected to the top of the inner horizontal plate, the ejector plate is fixedly connected to the top of the short rods, the cavity is opened at the top of the lower mold, the limiting angle rod is located on the movement trajectory of the driving wheel, the upper mold is movably connected to the outer circumferential surface of the driving screw, and the driving wheel is rotatably connected to the outer circumferential surface of the driving screw. The moving block is slidably connected to the inner wall of the C-frame. The driving block is connected to the inner wall of the C-frame by a spring. The guide post is located on the movement trajectory of the upper mold. The inner horizontal plate is connected to the inner wall of the lower mold by a spring. The ejector plate is slidably connected to the inner wall of the cavity. When the device operates, the starter motor drives the upper mold to rotate. When the upper mold rotates, it is driven to move downward by the spiral groove on the circumferential surface and the limiting rod. When the upper mold moves downward, it drives the drive wheel to move downward. During the movement, the drive wheel contacts the limiting angle rod and is guided by the inclined surface of the limiting angle rod, thus moving under the limitation of the C-frame. The movement of the drive wheel drives the drive block to move. The movement of the drive block drives the protective plate. After the protective plate moves, the inlet that is covered is blocked. When the upper and lower molds are fully engaged, the air vents are exposed to the outside. When the device is not in use, the protective plate can cover the inlet and air vents to prevent external debris from entering the inlet and air vents, thus affecting the quality of the finished product. When the upper mold moves downward under the drive screw, it will squeeze the guide post and make it move downward. The downward movement of the guide post will drive the inner horizontal plate to move downward. The downward movement of the inner horizontal plate will drive the short rod to move downward. The downward movement of the short rod will drive the ejector plate to move downward. When the upper and lower molds are fully engaged, the ejector plate will be embedded in the inner wall of the cavity. When the casting is completed and the upper and lower molds are opened, the guide post loses the limit of the upper mold and is reset by the spring at the bottom, thereby driving the ejector plate to rise and push out the finished product.

[0006] Preferably, the ejection mechanism includes a drive rack, a device column, a first gear, a hollow square rod, and a second gear. The drive rack is fixedly connected to the outer wall of the upper mold, the device column is fixedly connected to the outer wall of the lower mold, the first gear is rotatably connected to the inner wall of the device column, the hollow square rod is slidably connected to the inner wall of the limiting angle rod, and the second gear is fixedly connected to the left side of the first gear. The ejection mechanism also includes a guide hemisphere, a locking plate, and an oil guide groove. The second gear is rotatably connected to the inner wall of the hollow square rod, the locking plate is fixedly connected to the inner wall of the second gear, the guide hemisphere is slidably connected to the inner wall of the second gear, and the oil guide groove is formed on the outer circumferential surface of the guide hemisphere. The guide hemisphere and the locking plate are connected by a spring. The top outer wall of the lower mold is located on the movement trajectory of the guide hemisphere. The drive rack meshes with the second gear, and the first gear meshes with the hollow square rod. When the upper mold moves downward, it drives the drive rack to move downward. When the drive rack moves downward, it engages with transmission gear two, causing it to rotate. The rotation of gear two drives gear one to rotate. When gear one rotates, it engages with the rack at the bottom of the hollow square rod, causing it to move under the limit of the limiting angle rod. When the mold closes, the hollow square rod moves outward, driving gear two to move. During the movement of gear two, its circumferential surface contacts the top outer wall of the lower mold, causing it to rotate and drive the guide hemisphere to rotate. When the guide hemisphere moves to the other side, it is squeezed by the lower mold, causing the release agent inside to flow out along the guide oil groove and be evenly coated on the top of the lower mold. This prevents the finished product from sticking to the mold when the ejector plate ejects the finished product, thus preventing damage to the part. When the mold injection is completed and the mold opens, the drive rack moves upward, engaging gear two and causing it to rotate. The rotation of gear two drives gear one to rotate, causing the hollow square rod to move into the mold and cooperate with the ejector plate. The ejector plate ejects the part, and the hollow square rod pushes the part into the protective frame, thus allowing the finished part to be removed and collected.

[0007] Preferably, the collecting mechanism includes a protective frame, a guide plate, and a collecting frame. The protective frame is fixedly connected to the top of the housing, the guide plate is fixedly connected to the bottom of the housing, and the collecting frame is fixedly connected to the bottom of the guide plate. The collecting mechanism also includes a frame door, a sponge plate, a sliding column, and an L-shaped plate. The frame door is rotatably connected to the inner wall of the collecting frame, the sponge plate is slidably connected to the inner wall of the collecting frame, the sliding column is slidably connected to the inner wall of the sponge plate, and the L-shaped plate is fixedly connected to the bottom of the drive bar. The sponge plate is connected to the bottom inner wall of the collecting frame by a spring, and the L-shaped plate is slidably connected to the inner wall of the sponge plate. When the material enters the protective frame, it falls onto the top of the sponge plate along the guide plate. When a workpiece falls onto the top of the sponge board, its weight causes the board to move downwards along the limit of the sliding column, and then it is reset by a spring. This buffers and dissipates the force of the falling workpiece, preventing damage during the fall. When the finished workpiece falls into the collection box, it is blocked and isolated by the L-shaped plate. When the next workpiece is started, the upper and lower molds close, driving the drive bar to move downwards, which in turn moves the L-shaped plate downwards, allowing the workpiece to fall along the slope of the sponge board to the side near the frame door. When the next workpiece is finished, the upper and lower molds open, driving the drive bar to move upwards. The upward movement of the drive bar causes the L-shaped plate to move upwards, thus separating the next falling workpiece and preventing them from colliding and causing damage. This also facilitates the removal of the workpiece.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This continuous metal casting mold, with the cooperation of a protective plate, feed port, vent, upper mold, lower mold, and short rod, allows the feed port and vent, which were previously covered by the protective plate, to be exposed to the outside when the upper and lower molds are fully engaged. When the device is not in use, the protective plate can cover the feed port and vent to prevent external debris from entering and affecting the quality of the finished product. The short rod moves downward, causing the ejector plate to move downward. When the upper and lower molds are fully engaged, the ejector plate will be embedded in the inner wall of the cavity. When the casting is completed and the upper and lower molds are opened, the guide post loses the limit of the upper mold and is reset by the spring at the bottom, thereby driving the ejector plate to rise and push out the finished product, thus improving the production efficiency of the device, reducing labor costs, and achieving automatic material discharge to improve work efficiency.

[0009] 2. In this continuous metal casting mold, the gears, ejector plate, hollow square rod, and protective frame work together. The rotation of gear two drives gear one to rotate, thereby causing the hollow square rod to move into the mold and cooperate with the ejector plate. The ejector plate pushes the material out, and the hollow square rod pushes the material into the protective frame, thereby removing and collecting the finished material.

[0010] 3. This continuous metal casting mold, with the cooperation of the upper mold, lower mold, drive rack, and L-shaped plate, when the next part is completed, the upper mold and lower mold open, driving the drive rack to move upward. The upward movement of the drive rack drives the L-shaped plate to move upward, thereby separating the next falling part and preventing the parts from colliding and causing damage. It also facilitates the removal of the workpiece. Attached Figure Description

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Please see Figures 1-9 One embodiment of the present invention is as follows: a mold for continuous metal casting includes a frame 1, an upper mold 2 disposed inside the frame 1, a lower mold 3 fixedly connected inside the frame 1, a drive screw 4 rotatably connected inside the frame 1, a protective mechanism 5 disposed on the top of the upper mold 2, an ejection mechanism 6 disposed on the top of the lower mold 3, a collecting mechanism 7 disposed on the bottom of the frame 1, a limit rod 8 slidably connected to the inner wall of the frame 1, a motor disposed on the top of the drive screw 4, the protective mechanism 5 including an inlet 501, an air hole 502, a protective plate 503, a drive block 504, a drive wheel 505, a C-shaped frame 506, and a limit angle rod 507, the inlet 501 being opened on the inner wall of the upper mold 2, the air hole 502 being opened on the inner wall of the upper mold 2, the protective plate 503 being slidably connected to the top of the upper mold 2, the drive block 504 being fixedly connected to the rear of the protective plate 503, the drive wheel 505 being rotatably connected to the rear of the drive block 504, and the C-shaped frame 506 being... Fixedly connected to the top of the upper mold 2, the limiting angle rod 507 is fixedly connected to the outer wall of the lower mold 3. The protective mechanism 5 also includes an inner horizontal plate 508, a guide post 509, a short rod 510, an ejector plate 511, and a cavity 512. The inner horizontal plate 508 is slidably connected to the inner wall of the lower mold 3. The guide post 509 is fixedly connected to the top of the inner horizontal plate 508. The short rod 510 is fixedly connected to the top of the inner horizontal plate 508. The ejector plate 511 is fixedly connected to the top of the short rod 510. The cavity 512... 2 is opened on the top of the lower mold 3, the limiting angle rod 507 is located on the movement trajectory of the drive wheel 505, the upper mold 2 is movably connected to the outer circumferential surface of the drive screw 4, the drive block 504 is slidably connected to the inner wall of the C-shaped frame 506, the drive block 504 and the inner wall of the C-shaped frame 506 are connected by a spring, the guide post 509 is located on the movement trajectory of the upper mold 2, the inner horizontal plate 508 is connected to the inner wall of the lower mold 3 by a spring, and the ejection plate 511 is slidably connected to the inner wall of the cavity 512; The ejection mechanism 6 includes a drive rack 601, a device post 602, a first gear 603, a hollow square rod 604, and a second gear 605. The drive rack 601 is fixedly connected to the outer wall of the upper mold 2, the device post 602 is fixedly connected to the outer wall of the lower mold 3, the first gear 603 is rotatably connected to the inner wall of the device post 602, the hollow square rod 604 is slidably connected to the inner wall of the limiting angle rod 507, and the second gear 605 is fixedly connected to the left side of the first gear 603. The ejection mechanism 6 also includes a guide hemisphere 606 and a locking plate 607. The oil guide groove 608 and the second gear 605 are rotatably connected to the inner wall of the hollow square rod 604. The retaining plate 607 is fixedly connected to the inner wall of the second gear 605. The guide hemisphere 606 is slidably connected to the inner wall of the second gear 605. The oil guide groove 608 is opened on the outer circumferential surface of the guide hemisphere 606. The guide hemisphere 606 and the retaining plate 607 are connected by a spring. The top outer wall of the lower mold 3 is located on the movement trajectory of the guide hemisphere 606. The drive rack 601 meshes with the second gear 605, and the first gear 603 meshes with the hollow square rod 604. Working principle: When the device is in operation, the starting motor drives the upper mold 2 to rotate. As the upper mold 2 rotates, it moves downwards due to the spiral groove on the circumferential surface and the limiting rod 8. This downward movement of the upper mold 2 drives the drive wheel 505 downwards. During this movement, the drive wheel 505 contacts the limiting angle rod 507 and is guided by the inclined surface of the limiting angle rod 507, thus moving under the limiting of the C-frame 506. The movement of the drive wheel 505 drives the drive block 504 to move, which in turn drives the protective plate 503. After the protective plate 503 moves, the inlet 501 and air hole 502, which were previously covered, are exposed when the upper mold 2 and lower mold 3 are fully engaged. When the device is not in use, the protective plate 503 can cover the inlet 501 and air hole 502. The vent 502 covers and prevents external debris from entering the feed port 501 and the vent 502, thus affecting the quality of the finished product produced by the device. When the upper mold 2 moves downward under the drive of the drive screw 4, it will squeeze the guide post 509 and make it move downward. The guide post 509 moves downward, which drives the inner horizontal plate 508 to move downward. The inner horizontal plate 508 moves downward, which drives the short rod 510 to move downward. The short rod 510 moves downward, which drives the ejector plate 511 to move downward. When the upper mold 2 and the lower mold 3 are fully engaged, the ejector plate 511 will be embedded in the inner wall of the cavity 512. When the casting is completed and the upper mold 2 and the lower mold 3 are opened, the guide post 509 loses the limit of the upper mold 2 and is reset by the spring at the bottom, which drives the ejector plate 511 to rise and push out the finished product. When the upper mold 2 moves downward, it drives the drive rack 601 to move downward. As the drive rack 601 moves downward, it meshes with the transmission gear 605, causing it to rotate. The rotation of gear 605 causes gear 603 to rotate. When gear 603 rotates, it meshes with the rack at the bottom of the hollow square rod 604, causing it to move under the limit of the limiting angle rod 507. When the mold closes, the hollow square rod 604 moves outward, causing gear 605 to move. During the movement of gear 605, its circumferential surface contacts the top outer wall of the lower mold 3, causing it to rotate and drive the guide hemisphere 606 to rotate. When the guide hemisphere 606 moves to the other side, it is then... 3. The extrusion causes the internal release agent to flow out along the guide groove 608 and be evenly coated on the top of the lower mold 3, preventing the finished product from sticking to the mold when the ejector plate 511 ejects the finished product, thus causing damage to the material. When the mold injection is completed and the mold is opened, the drive rack 601 moves upward to mesh with the second gear 605 to rotate. The rotation of the second gear 605 drives the first gear 603 to rotate, thereby causing the hollow square rod 604 to move into the mold and cooperate with the ejector plate 511. The ejector plate 511 ejects the material, and the hollow square rod 604 pushes the material into the protective frame 701, thereby removing and collecting the finished material.

[0015] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the collection mechanism 7 includes a protective frame 701, a guide plate 702, and a collection frame 703. The protective frame 701 is fixedly connected to the top of the housing 1, the guide plate 702 is fixedly connected to the bottom of the housing 1, and the collection frame 703 is fixedly connected to the bottom of the guide plate 702. The collection mechanism 7 also includes a frame door 704, a sponge plate 705, a sliding column 706, and an L-shaped plate 707. The frame door 704 is rotatably connected to the inner wall of the collection frame 703, the sponge plate 705 is slidably connected to the inner wall of the collection frame 703, the sliding column 706 is slidably connected to the inner wall of the sponge plate 705, and the L-shaped plate 707 is fixedly connected to the bottom of the drive rack 601. The sponge plate 705 is connected to the bottom inner wall of the collection frame 703 by a spring, and the L-shaped plate 707 is slidably connected to the inner wall of the sponge plate 705.

[0016] Working principle: When the workpiece enters the protective frame 701, it falls along the guide plate 702 to the top of the sponge plate 705. When the workpiece falls to the top of the sponge plate 705, the weight of the workpiece itself causes the sponge plate 705 to move downward along the limit of the sliding column 706 and finally be reset by the spring. This buffers and unloads the falling workpiece to prevent damage during the fall. When the finished workpiece falls into the collection frame 703, it is blocked and isolated by the L-shaped plate 707. When the next workpiece is started, the upper mold 2 and the lower mold 3 close the mold and drive the toothed bar 601 to move downward, thereby causing the L-shaped plate 707 to move downward, allowing the workpiece to fall along the slope of the sponge plate 705 to the side near the frame door 704. When the next workpiece is finished, the upper mold 2 and the lower mold 3 open the mold and drive the toothed bar 601 to move upward. The upward movement of the toothed bar 601 causes the L-shaped plate 707 to move upward, thereby separating the next falling workpiece to prevent the workpieces from colliding and causing damage. It also facilitates the removal of the workpiece.

[0017] This invention provides a mold for continuous metal casting. Many methods and approaches exist for implementing this technical solution; the above are merely preferred embodiments. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
