Description

Technical Field

[0001] This invention belongs to the field of metal casting technology, and in particular relates to an aluminum ingot casting device. Background Technology

[0002] Aluminum, used as a raw material in everyday industry, is called aluminum ingot. The casting process of aluminum ingots is a physical process in which liquid aluminum cools and crystallizes into solid aluminum ingots. In the non-ferrous metals industry, it is necessary to further promote the comprehensive utilization of resources and energy conservation and emission reduction, especially the comprehensive utilization of resources and energy such as smelting slag, waste gas, waste liquid, and waste heat and pressure. The aluminum ingot casting process is not only the forming stage, but also a key node in achieving comprehensive resource utilization and energy conservation and emission reduction.

[0003] Traditional aluminum ingot casting processes, including aluminum ingot casting, cooling and forming, demolding, and secondary cooling after demolding, do not fully realize the effective utilization of waste heat in this series of processes.

[0004] First, the mold needs to be preheated before casting. Traditional cold casting can easily cause the aluminum liquid to solidify too quickly, resulting in defects and high energy consumption. Therefore, the mold needs to be preheated before casting. In addition, the temperature of the mold needs to be maintained during continuous casting. Therefore, mold heating equipment is often required, using natural gas, electromagnetic induction, or other methods to heat and keep the mold warm. For continuous casting production, a large amount of energy is required.

[0005] Secondly, in the cooling and forming stage, it is necessary to rapidly cool the aluminum ingot to achieve high-speed production, while controlling the mold to prevent over-cooling to maintain its optimal operating temperature and save energy. A complete mold temperature cycle during production is as follows: Casting point (ideal condition): When the mold reaches below the aluminum liquid distributor, its ideal temperature should be maintained at 150°C - 200°C. This temperature can ensure that the aluminum liquid will not solidify rapidly due to the mold being too cold, resulting in surface defects.

[0006] Spray cooling stage: This is the main stage of mold temperature change. The heat carried away by the cooling water comes not only from the aluminum ingot but also from the mold itself. The mold temperature rises sharply from 150-200°C during casting (due to the absorption of heat from the molten aluminum) and then drops rapidly. At the demolding point, the mold temperature after demolding is typically between 180°C and 280°C.

[0007] Post-demolding and return process: After demolding, the mold no longer has an internal heat source (aluminum ingot) and continues to dissipate heat into the air. Its temperature continues to drop during the return process to the distributor. When the mold returns to the distributor position, its temperature typically drops to 100°C-150°C, or even lower (especially when the ambient temperature is low, the casting speed is slow, or the equipment is long).

[0008] In traditional casting processes, most of the heat from the high-temperature aluminum ingots after demolding (which are still 400-500°C when demolded) is wasted in the environment during the process of being transported to the secondary cooling equipment, resulting in a waste of thermal energy. During the process of the mold returning to the casting position after demolding, the mold continues to cool down, and mold heating and insulation equipment is required to precisely control the mold temperature, which further aggravates energy consumption.

The aluminum ingot casting line is equipped with a guiding mechanism at the demolding station. The guiding mechanism includes a guide block arranged in a ring on the outside of the mold. The guide block is used to restrict the aluminum ingot to remain inside the mold at the demolding position. A detection block is horizontally arranged on the bottom side of the guide block. The height of the detection block is slightly lower than the height of the aluminum ingot conveying line, and the height of the aluminum ingot conveying line is slightly lower than the height of the first conveyor chain on the bottom side of the aluminum ingot casting line.

The upper part of the aluminum ingot is placed inside the mold for heating and heat preservation of the mold. The aluminum ingot conveying line and the aluminum ingot casting line operate synchronously, transporting the mold and the aluminum ingot to the bottom side of the casting station simultaneously.

A mounting block is provided on the bottom side of the lifting groove, and a first spring is mounted on the mounting block, the first spring being in contact with the bottom side of the lifting seat. A distance sensor is provided on the mounting block. When the detection roller is not under pressure, the upper side of the detection roller is slightly higher than the height of the aluminum ingot conveyor line. When the aluminum ingot is demolded and conveyed on the aluminum ingot conveyor line, it can squeeze the detection roller down, thereby detecting the height change through the distance sensor.

The centers of the two rotating grooves coincide with the first striking point Q1 and the second striking point Q2, respectively. The guide roller is slidably fitted in the rotating groove and the limiting groove. When the guide roller is fitted in the rotating groove, the first ball is compressed and housed inside the guide roller. When the guide roller is fitted in the limiting groove, the first ball extends out from inside the guide roller and adheres to the inner wall of the limiting groove. When the sliding seat is located at the first striking point Q1 or the second striking point Q2, the second cylinder extends and retracts to drive the second pendulum to swing and strike the mold, and the guide roller slides in the rotating groove. When the sliding seat is located at the first striking point Q1, the second cylinder retracts to drive the second pendulum away from the mold, and the guide roller moves into the limiting groove. The third cylinder extends to transfer the sliding seat from the first striking point Q1 to the second striking point Q2. When the sliding seat is located at the second striking point Q2, the second cylinder retracts to drive the second pendulum away from the mold, and the guide roller moves into the limiting groove. The third cylinder retracts to transfer the sliding seat from the second striking point Q2 to the first striking point Q1.

[0015] Optionally, the second demolding mechanism further includes a locking assembly for fixing the second rotating shaft when the third cylinder drives the sliding seat to move; The horizontal groove is provided with a first striking point Q1 and a second striking point Q2 at intervals, and the upper inner wall of the horizontal groove is provided with two slots corresponding to the first striking point Q1 and the second striking point Q2 at intervals.

A third spring is provided on the outer wall of the guide cylinder. The bottom side of the upper end of the guide cylinder is in close contact with the third spring. The bottom side of the third spring is disposed on the end face of the stepped hole. When the sliding seat is located at the first striking point Q1 or the second striking point Q2, the second ball is set in the slot and the brake block is away from the second rotating shaft; When the sliding seat is adjusted to the sliding position, the second ball disengages from the first striking point Q1 or the second striking point Q2, and the linkage brake block presses against the second rotating shaft.

[0016] Optionally, the aluminum ingot casting line further includes four first sprockets, which are rotatably mounted on a first mounting frame; the inner wall of the first mounting frame is provided with a first track, and the bottom horizontal section of the first conveyor chain moves close to the first track.

[0017] Optionally, the aluminum ingot conveying line includes a second conveying chain connected end to end, and mold insulation stations and aluminum ingot cooling stations are arranged sequentially along the horizontal section of the first conveying chain; the aluminum ingot casting line also includes four second sprockets, which are rotatably mounted on a second mounting frame; the inner wall of the second mounting frame is provided with a second track, and the bottom horizontal section of the second conveying chain moves close to the second track.

[0020] The present invention has the following advantages and beneficial effects: In this invention, a chain-type continuous aluminum ingot casting system is designed. Through the concept of "synchronous heat preservation," the residual heat of the aluminum ingot itself is used to maintain the mold temperature, replacing external heating equipment such as natural gas, thereby achieving energy conservation and consumption reduction. The high-temperature aluminum ingot after demolding (still 400-500°C at demolding) utilizes its residual heat, avoiding the waste of most heat into the environment. During the process of the mold returning to the casting position after demolding, the demolded aluminum ingot and mold are transported synchronously. The demolded aluminum ingot is located inside the mold, enabling efficient heating and heat preservation. The aluminum ingot is used to heat and preserve the mold. When the mold is about to return to the bottom of the casting position, the aluminum ingot and mold are moved away, eliminating the need for mold heating and heat preservation equipment, greatly reducing energy consumption.

[0021] Secondly, this invention also designs a mechanism to improve demolding efficiency. Demolding is achieved using a cylinder-driven striking mechanism, and the entire striking mechanism can be laterally adjusted to change the striking position, thus functioning similarly to a follow-up striking mechanism. This ensures that the same mold can be continuously struck at multiple points, thereby improving the demolding effect. Simultaneously, when the striking mechanism is adjusting its striking position laterally, a locking component is used to fix the striking mechanism, preventing it from swinging and colliding with the mold. This ensures the reliability and stability of the striking mechanism's position adjustment and also guarantees that the position of the pendulum remains fixed during the adjustment process. Therefore, subsequent striking can be performed directly using the original design parameters without the need for secondary adjustments. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 some embodiments of the present invention, but not all embodiments.

[0025] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0026] Example 1 like Figures 1 to 8 As shown, an aluminum ingot casting equipment includes an aluminum ingot casting line 4 and an aluminum ingot conveying line 2 disposed on the bottom side of the aluminum ingot casting line 4. The aluminum ingot casting line 4 is used to cast aluminum ingots 45 and demold them, and the aluminum ingot conveying line 2 is used to receive and convey the demolded aluminum ingots 45.

[0027] like Figures 1 to 8 As shown, the aluminum ingot casting line 4 includes a first conveyor chain 41 connected end to end, and multiple molds 43 are fixedly installed on the first conveyor chain 41 at a preset interval. Casting station, cooling station and demolding station are arranged sequentially along the horizontal section of the first conveyor chain 41.

[0028] like Figures 1 to 8 As shown, the aluminum ingot casting line 4 also includes four first sprockets 31. Two first sprockets 31 form a group, and the two first sprockets 31 in the same group are connected by a first connecting shaft 311. The first sprockets 31 are rotatably mounted on the first mounting frame 32 via the first connecting shaft 311. The inner wall of the first mounting frame 32 is symmetrically provided with two first tracks 391 via first track seats 39. The bottom horizontal section of the first conveyor chain 41 moves close to the first track 391, thereby limiting the movement of the bottom horizontal section of the first conveyor chain 41.

[0029] like Figures 1 to 8 As shown, the aluminum ingot conveying line 2 includes a second conveyor chain 21 connected end to end. A mold insulation station and an aluminum ingot cooling station are arranged sequentially along the horizontal section of the second conveyor chain 21. The mold insulation station is located on the bottom side of the aluminum ingot conveying line 2, and the aluminum ingot cooling station is located on the outside of the aluminum ingot conveying line 2. A cooling box 10 is installed at the aluminum ingot cooling station to finally cool the aluminum ingots using water cooling to meet stacking requirements. The aluminum ingot casting line 4 also includes four second sprockets 12. Two second sprockets 12 form a group, and the two second sprockets 12 in the same group are connected by a second connecting shaft 11. The second sprockets 12 are rotatably mounted on a second mounting frame 13 via the second connecting shaft 11. Two second tracks 151 are symmetrically arranged on the inner wall of the second mounting frame 13 via second track seats 15. The upper horizontal section of the second conveyor chain 21 moves close to the second track 151, achieving movement limitation of the upper horizontal section of the second conveyor chain 21.

[0030] Reference Figure 8By limiting the first track 391 and the second track 151, it is ensured that the bottom horizontal section of the first conveyor chain 41 and the upper horizontal section of the second conveyor chain 21 are conveyed in parallel, and the bottom horizontal section of the first conveyor chain 41 is located above the upper horizontal section of the second conveyor chain 21. The purpose is to ensure that the mold 43 and the aluminum ingot 45 can be separated by a certain interval, so that the aluminum ingot 45 can be placed on the upper horizontal section of the second conveyor chain 21 for parallel conveying after demolding, and conveyed synchronously with the mold 43, so as to achieve the effect of synchronous conveying of the mold 43 and the aluminum ingot 45 and heating and heat preservation of the mold 43.

[0031] like Figure 5 ,like Figure 7 , Figure 8 and Figure 16 As shown, both the first conveyor chain 41 and the second conveyor chain 21 are composed of several chain links hinged together by pins 421. Guide wheels are sleeved on the pins 421. The first conveyor chain 41 is provided with a first guide wheel 42, and the second conveyor chain 21 is provided with a second guide wheel 22. The first guide wheel 42 is fitted on the first track 391, and the second guide wheel 22 is fitted on the second track 151, thereby realizing the smooth guiding movement of the first conveyor chain 41 and the second conveyor chain 21, ensuring the stable and synchronous conveying of the mold 43 and the aluminum ingot 45.

[0032] like Figure 6 As shown, the aluminum ingot casting line 4 is driven by the first motor 3. The first motor base 33 is fixed on the outside of the first mounting bracket 32 ​​on one side. The first motor 3 is mounted on the first motor base 33. The output shaft of the first motor 3 is connected to the first connecting shaft 311 for transmission, thereby driving the first sprocket 31 and the first transmission chain 41 to move.

[0033] like Figure 6 As shown, an aluminum liquid distributor 5 is provided at the aluminum ingot casting station, that is, on the side near the first motor 3. The aluminum liquid distributor 5 is located on the upper side of the mold 43. An aluminum inlet 52 is provided on one side of the aluminum liquid distributor 5. The aluminum liquid from the smelting furnace enters the aluminum inlet 52 through the chute and reaches the interior of the aluminum liquid distributor 5. Several aluminum outlet pipes 51 are arranged around the circumference of the aluminum liquid distributor 5. During the rotation of the aluminum liquid distributor 5, the aluminum liquid is evenly distributed to the casting cavity 44 of the bottom mold 43 through the aluminum outlet pipes 51.

[0034] like Figure 6As shown, an aluminum liquid distributor 5 has a mounting shaft 53 on one side, and a support frame 38 on one side of the first motor 3. A bearing seat 37 is located at the upper end of the support frame 38. The mounting shaft 53 is rotatably mounted in the bearing seat 37. A first pulley 34 is connected to one side of the output shaft of the first motor 3, and a second pulley 36 is connected to one side of the mounting shaft 53. The first pulley 34 and the second pulley 36 are connected and driven by a belt 35. With this structure, the aluminum liquid distributor 5 rotates simultaneously as the first motor 3 drives the aluminum ingot casting line 4.

[0035] like Figure 5 As shown, the aluminum ingot conveying line 2 is driven by the second motor 1. The second motor base 14 is fixed on the outside of the second mounting bracket 13 on one side. The second motor 1 is mounted on the second motor base 14. The output shaft of the second motor 1 is connected to the second connecting shaft 11 for transmission, thereby driving the second sprocket 12 and the second conveying chain 21 to move.

[0036] like Figures 1 to 15 As shown, the aluminum ingot casting line 4 is equipped with a guiding mechanism at the demolding station. The demolding station is located at the position of the first sprocket 31 on the side away from the aluminum liquid distributor 5. The guiding mechanism includes a guide block 6 arranged in a ring outside the mold 43. The guide block 6 is arranged outside the position of the first sprocket 31 and is used to surround and limit the mold 43 arranged in a ring at the demolding position. The guide block 6 is used to limit the aluminum ingot 45 to remain in the mold 43 at the demolding position and prevent the aluminum ingot 45 from leaving the mold 43 after demolding.

[0037] like Figures 1 to 15 As shown, a detection block 61 is horizontally arranged on the bottom side of the guide block 6. The height of the detection block 61 is slightly lower than the height of the aluminum ingot conveying line 2. The detection block 61 is located inside the second conveying chain 21 and will not interfere with the movement of the second conveying chain 21. The width of the aluminum ingot casting line 4 is greater than the width of the aluminum ingot conveying line 2, and the height of the aluminum ingot conveying line 2 is slightly lower than the height of the first conveying chain 41 on the bottom side of the aluminum ingot casting line 4, ensuring that when the mold 43 is horizontally conveyed after demolding, the bottom side of the mold 43 will not contact the aluminum ingot conveying line 2. When the mold 43 detaches from the guide block 6 and reaches above the detection block 61, the aluminum ingot 45 detaches from the mold 43 and is supported on the aluminum ingot conveying line 2. The upper part of the aluminum ingot 45 is placed inside the mold 43 for heating and heat preservation of the mold 43 (e.g., Figure 12 As shown), the aluminum ingot conveying line 2 and the aluminum ingot casting line 4 operate synchronously, conveying the mold 43 and the aluminum ingot 45 to the bottom side of the casting station simultaneously.

[0038] In this invention, a chain-type continuous aluminum ingot casting system is designed. Through the concept of "synchronous heat preservation," the residual heat of the aluminum ingot 45 is used to maintain the temperature of the mold 43, replacing external heating equipment such as natural gas, thereby achieving energy saving and consumption reduction. The high-temperature aluminum ingot 45 after demolding (still 400-500°C at demolding) utilizes its residual heat, avoiding most of the heat being wasted into the environment and causing thermal energy waste. During the process of the mold 43 returning to the casting position after demolding, the demolded aluminum ingot 45 and the mold 43 are transported synchronously. The demolded aluminum ingot 45 is located inside the mold 43, such as... Figure 12 As shown, the upper part of the aluminum ingot 45 is located inside the mold 43, and there is a certain cavity between the aluminum ingot 45 and the mold 43, which can achieve sufficient preheating and heat preservation, and the heat is not easily dissipated, thus enabling efficient preheating and heat preservation of the mold. Using the aluminum ingot 45 to heat and preserve the mold 43, when the mold 43 is about to return to the bottom of the casting position, the aluminum ingot 45 and the mold 43 are moved away, eliminating the need for heating and heat preservation equipment for the mold 43, greatly reducing energy consumption.

[0039] Furthermore, the design that partially surrounds the mold and aluminum ingot not only allows for preheating and insulation of the mold, but also prevents most of the heat loss of the aluminum ingot through heat exchange with the air. This ensures that the aluminum ingot still has a sufficiently high temperature when it reaches the subsequent cooling box 10, allowing for efficient heat exchange of the aluminum ingot using the cooling box 10. This enables the utilization of hot water resources or steam, thereby improving the waste heat utilization efficiency of the aluminum ingot.

[0040] Example 2 In this embodiment, a demolding mechanism is further designed at the demolding station to increase demolding efficiency and prevent missed inspections of undemolded molds, and to perform a second, efficient and accurate demolding of the undemolded mold 43.

[0041] like Figures 1 to 15 and 18~ Figure 29As shown, a mounting base 63 is horizontally positioned in the middle of the guide block 6. A first hinge block 631 is mounted on the mounting base 63, and a first shaft hole 632 is located at the end of the mounting base 63. A first demolding mechanism is mounted on the mounting base 63, comprising a first cylinder 7, a first swing frame 73, a first swing arm 75, and a first pendulum 76. A first rotating shaft 74 is located on the bottom side of the first swing frame 73, and the first rotating shaft 74 is rotatably mounted in the first shaft hole 632 on the mounting base 63 via a bearing. A first hinge joint 71 is located at one end of the first cylinder 7, and the first hinge joint 71 is hinged to the first hinge block 631. The first piston rod 72 of the first cylinder 7 is hinged to the upper side of the first swing frame 73. First swing arms 75 are respectively mounted on both sides of the first rotating shaft 74, and the first swing arms 75 and the first swing frame 73 are bent at a fixed angle. A first pendulum 76 is mounted at the end of the first swing arm 75. The first pendulum 76 is located on both sides of the guide block 6 and is used to knock the mold 43 for demolding. When the first cylinder 7 extends or retracts, it continuously controls the first pendulum 76 to strike the molds 43 on both sides of the guide block 6, thereby achieving demolding.

[0042] like Figures 1 to 15 and 18~ Figure 29 As shown, the detection block 61 is equipped with a second demolding mechanism, which includes a second cylinder 8, a second swing frame 83, a second swing arm 85, a second pendulum 86, a third cylinder 89, and a sliding seat 87. The sliding seat 87 has a second shaft hole 871 inside. A second rotating shaft 84 is located on the upper side of the second swing frame 83, and the second rotating shaft 84 is rotatably mounted in the second shaft hole 871 of the sliding seat 87 via a bearing. A base 62 is located on the bottom side of the detection block 61, and the base 62 is fixed to the first mounting bracket 32. A second hinge block 65 is located on the bottom side of the base 62. A second hinge joint 81 is located at one end of the second cylinder 8, and the second hinge joint 81 is hinged to the second hinge block 65. The second piston rod 82 of the second cylinder 8 is hinged to the bottom side of the second swing frame 83; the second swing arms 85 are respectively provided on both sides of the second rotating shaft 84, and the second swing arms 85 and the second swing frame 83 are bent at a fixed angle. The second swing arm 85 is equipped with a second pendulum 86 at its end; the second pendulum 86 is provided on both sides of the detection block 61 for knocking the mold 43 to demold. The detection block 61 is provided with a horizontal groove 612 inside, and the sliding seat 87 is slidably provided in the horizontal groove 612. The bottom side of the horizontal groove 612 is provided with a sliding groove 613, and the bottom side of the sliding seat 87 is provided with a slider 878 that fits in the sliding groove 613. The sliding seat 87 is located on the upper side of the second cylinder 8, and the third cylinder 89 is located inside the detection block 61. The third piston rod 88 of the third cylinder 89 is connected to the sliding seat 87 and is used to drive the sliding seat 87 to move horizontally to adjust the knocking position.

[0043] Reference Figure 10 and Figure 11As shown, this invention adds a second demolding mechanism to the first demolding mechanism. The purpose is to perform a second demolding of the mold 43 that has not yet been demolded after being struck by the first mold 43 mechanism. This second demolding mechanism is driven by a dual-cylinder and can move horizontally to adjust the position of the demolding strike. It can then follow the movement of the undemolded mold 43, continuously striking it to ensure the reliability of the second demolding.

[0044] This invention utilizes a cylinder-driven knocking mechanism for demolding. The entire knocking mechanism can be horizontally adjusted to change the knocking position, thus functioning similarly to a follow-up knocking mechanism. This ensures that the same mold 43 can be continuously knocked at multiple points, thereby improving the demolding effect. Since aluminum ingot casting is relatively slow, the transport speed of the mold 43 is also relatively slow. Therefore, for molds 43 that have not been demolded after being knocked by the first demolding mechanism, the third cylinder 89 is first extended to the first knocking point. Then, the second cylinder 8 continuously extends and retracts, controlling the second pendulum 86 to knock, achieving a second knocking demolding. Subsequently, the third cylinder 89 retracts, quickly reaching the second knocking point, and waits for the previously knocked mold 43 to reach the second knocking position. Then, the second cylinder 8 continuously extends and retracts, controlling the second pendulum 86 to knock, achieving a third knocking demolding. This follow-up knocking demolding ensures that molds that have not been demolded initially can be continuously knocked out in subsequent knocking operations, ensuring the reliability of demolding.

[0045] Furthermore, slide rods 64 are slidably mounted on both sides of the detection block 61. The slide rods 64 are fixed to the first mounting bracket 32, and adjusting nuts 641 are threadedly connected to both sides of the slide rods 64. The adjusting nuts 641 are fixed tightly against the side wall of the detection block 61. This structure allows for the lateral adjustment of the positions of the detection block 61 and the guide block 6, so that the guide block 6 is close to the mold 43 outside the first sprocket 31, and then fixed using the adjusting nuts 641.

[0046] Example 3 like Figures 11-15 and Figure 17 As shown, the present invention includes a demolding detection mechanism on the detection block 61. Several lifting grooves 611 are evenly distributed on the upper side of the detection block 61. The demolding detection mechanism includes a detection roller 9, with both sides of the detection roller 9 connected to a lifting seat 91, which is slidably disposed within the lifting grooves 611. A mounting block 93 is provided on the bottom side of the lifting grooves 611, and a first spring 92 is mounted on the mounting block 93, which is in contact with the bottom side of the lifting seat 91. A distance sensor 94 is mounted on the mounting block 93, located inside the first spring 92. When the detection roller 9 is not under pressure, its upper side is slightly higher than the height of the aluminum ingot conveying line 2. When the aluminum ingot 45 is demolded and conveyed on the aluminum ingot conveying line 2, it can squeeze the detection roller 9 downwards, thereby detecting the height change through the distance sensor 94.

[0047] This demolding detection mechanism is used to detect the demolding of mold 43 after the first demolding mechanism strikes it. Specifically, if mold 43 and aluminum ingot 45 separate, the aluminum ingot 45 is demolded and conveyed on the aluminum ingot conveyor line 2, causing the detection roller 9 to descend, thus detecting a height change via distance sensor 94, indicating that mold 43 has been successfully demolded. Conversely, if mold 43 and aluminum ingot 45 do not separate, the aluminum ingot 45 adheres to the inside of mold 43 and is not conveyed on the aluminum ingot conveyor line 2. In this case, the aluminum ingot 45 will not press the detection roller 9 to descend, and distance sensor 94 cannot detect a height change, thus indicating that mold 43 has not been successfully demolded.

[0048] Most of the aluminum ingots 45 can be demolded through the first demolding mechanism. Only a small number of molds 43 cannot be demolded. The demolding detection mechanism is used to detect the molds 43 that have not been demolded and to demold them by knocking them a second time using the subsequent second demolding mechanism.

[0049] Example 4 When the second demolding mechanism is running, the striking parameters need to be preset. For example, during striking, the second cylinder 8 strikes the mold 43 three times at the same striking point, and the swing angle of each strike is controlled at a certain angle. That is, the extension and retraction stroke of the second cylinder 8 during striking is preset. This requires that when the third cylinder 89 extends and retracts to different striking positions, the second cylinder 8 can achieve precise and reliable preset control to ensure that each time the striking position is adjusted, it can strike accurately according to the preset parameters, avoiding over-striking or insufficient striking force.

[0050] Secondly, during the adjustment of the striking position by the extension and retraction of the third cylinder 89, the second cylinder 8 is in a depressurized state and can extend and retract freely. Since the second swing arm 83 is hinged to the sliding seat 87 and the second piston rod 82, the second swing arm 83 will swing uncontrollably during the extension and retraction of the third cylinder 89. This causes the position of the second pendulum 86 to change during the adjustment process, and may even cause the second pendulum 86 to swing and collide with the mold 43, causing damage. In other words, during the adjustment of the striking position by the extension and retraction of the third cylinder 89, the second pendulum 86 must retract away from the mold 43 to maintain a safe distance, and it must not swing during this process. This ensures that after the striking position is adjusted, the pendulum is in the same preset position at each striking position, facilitating precise control during subsequent striking.

[0051] In summary, this embodiment has been further optimized.

[0052] like Figures 9 to 29As shown, the second demolding mechanism also includes a locking component, which is used to fix the second swing frame 83 when the third cylinder 89 drives the sliding seat 87 to move, to prevent the second swing frame 83 from rotating, and to ensure that the position of the second swing hammer 86 remains fixed when adjusting the striking position.

[0053] Specifically: The locking assembly includes guide rollers 831 and first ball bearings 832. The second swing frame 83 is U-shaped, with two guide rollers 831 on each side of the second swing frame 83. The guide rollers 831 are symmetrically arranged on the outer wall of the second swing frame 83, and the first ball bearings 832, which can be elastically compressed and reset, are arranged inside the guide rollers 831. A base 62 is provided on the bottom side of the detection block 61, and clearance grooves 621 are provided on both sides of the base 62. The second swing frame 83 is respectively positioned in the clearance grooves 621 on both sides. Horizontal limiting grooves 622 are provided on the inner walls of both sides of the clearance grooves 621. An arc-shaped rotating groove 623 extends from both ends of the limiting groove 622 to the bottom side. The depth of the limiting groove 622 is greater than the depth of the rotating groove 623. A first striking point Q1 and a second striking point Q2 are spaced apart on the horizontal groove 612. The centers of the two rotating grooves 623 coincide with the first striking point Q1 and the second striking point Q2, respectively. The guide roller 831 is slidably fitted in the rotating groove 623 and the limiting groove 622. When the guide roller 831 is fitted in the rotating groove 623, the first ball 832 is compressed and housed inside the guide roller 831. When the guide roller 831 is fitted in the limiting groove 622, the first ball 832 extends out from inside the guide roller 831 and adheres to the inner wall of the limiting groove 622.

[0054] Tapping process: When the sliding seat 87 is located at the first striking point Q1 or the second striking point Q2, the rotation trajectory of the guide roller 831 on the second swing frame 83 coincides with the rotation groove 623. That is, when the second cylinder 8 extends and retracts to drive the second pendulum 86 to swing and strike the mold 43, the guide roller 831 slides in the rotation groove 623.

[0055] Tapping position adjustment process: When the sliding seat 87 is at the first striking point Q1, the second cylinder 8 retracts to drive the second pendulum 86 away from the mold 43. When the second pendulum 86 reaches its farthest limit position away from the mold 43, the guide roller 831 moves into the limiting groove 622. At this time, the first ball 832 pops out into the limiting groove 622 to achieve initial limiting. Then, the third cylinder 89 is extended. Due to inertia and the limiting of the first ball 832, during the process of transferring the sliding seat 87 from the first striking point Q1 to the second striking point Q2, the guide roller 831 will be limited to lateral movement in the limiting groove 622, and the second pendulum frame 83 cannot rotate, thus fixing the second pendulum 86 when the third cylinder 89 extends and retracts to adjust the striking position.

[0056] When the sliding seat 87 is at the second striking point Q2, the second cylinder 8 retracts, driving the second pendulum 86 away from the mold 43. When the second pendulum 86 reaches its farthest limit position away from the mold 43, the guide roller 831 moves into the limiting groove 622. At this time, the first ball 832 pops out into the limiting groove 622 to achieve initial limiting. Then, the third cylinder 89 is controlled to retract. Due to inertia and the limiting of the first ball 832, during the process of transferring the sliding seat 87 from the second striking point Q2 to the first striking point Q1, the guide roller 831 will be limited to lateral movement in the limiting groove 622, and the second pendulum frame 83 cannot rotate, thus fixing the second pendulum 86 when the third cylinder 89 extends and retracts to adjust the striking position.

[0057] This structure is simple and ingenious. At the striking position, the second cylinder 8 can be extended and retracted to achieve striking demolding. When adjusting the striking position, it can prevent the second pendulum 86 from swinging, ensuring that the second pendulum 86 retracts away from the mold 43 to maintain a safe distance. Furthermore, it does not swing during the process of adjusting the striking position by extending and retracting the third cylinder 89. This ensures that after adjusting the striking position, the pendulum is in the same preset position at each different striking position, which facilitates precise control during subsequent striking.

[0058] Example 5 This embodiment proposes a second locking assembly, which is used to fix the second rotating shaft 84 when the third cylinder 89 drives the sliding seat 87 to move.

[0059] like Figure 11 , Figures 23-30 As shown, a first striking point Q1 and a second striking point Q2 are spaced apart on the horizontal groove 612, and two slots 614 corresponding to the first striking point Q1 and the second striking point Q2 are spaced apart on the upper inner wall of the horizontal groove 612. The sliding seat 87 has a second shaft hole 871 and a stepped hole 872 communicating with the second shaft hole 871.

[0060] The locking assembly includes a brake block 877 and a second ball bearing 874. The brake block 877 is disposed inside the sliding seat 87. A guide cylinder 873 is integrally formed on the upper end of the brake block 877. The guide cylinder 873 is vertically mounted in the stepped hole 872 of the sliding seat 87. A second spring 875 is disposed on the inner wall of the guide cylinder 873, and the upper end of the second spring 875 is connected to the second ball bearing 874. A third spring 876 is disposed on the outer wall of the guide cylinder 873. The bottom side of the upper end of the guide cylinder 873 is in close contact with the third spring 876, and the bottom side of the third spring 876 is disposed on the end face of the stepped hole 872. A second rotating shaft 84 is disposed in a second shaft hole 871, and a brake wheel 841 is disposed on the outer side of the second rotating shaft 84.

[0061] Tapping process: When the sliding seat 87 is located at the first striking point Q1 or the second striking point Q2, the second ball bearing 874 is positioned in the slot 614. At this time, the second spring 875 and the third spring 876 are not compressed, and the brake block 877 is away from the brake wheel 841 of the second rotating shaft 84. Therefore, the second cylinder 8 can freely extend and retract, driving the second swing frame 83 and the second rotating shaft 84 to rotate, thereby realizing the swinging and striking demolding of the second pendulum 86.

[0062] Tapping position adjustment process: When the sliding seat 87 slides to adjust its position, the third cylinder 89 extends or retracts, and the second ball bearing 874 disengages from either the first striking point Q1 or the second striking point Q2. At this time, the second spring 875 and the third spring 876 are compressed, and the linkage brake block 877 presses against the brake wheel 841 of the second rotating shaft 84, thus fixing the second rotating shaft 84. Therefore, during the extension and retraction of the third cylinder 89, the second rotating shaft 84 is fixed, thereby fixing the second pendulum 86 and preventing it from swinging and colliding with the mold 43. This ensures the reliability and stability of the striking mechanism's adjustment of the striking position, and also ensures that the position of the pendulum remains fixed during the adjustment process. Consequently, subsequent striking can be performed directly using the original design parameters without the need for secondary adjustments.

Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
