Description

Technical Field

[0001] This invention relates to the field of parts casting technology, and in particular to an intelligent casting island for casting a gear chamber cover. Background Technology

[0002] The gear chamber cover is an important component of the engine. Its size and specifications are determined according to the engine model, and it is usually manufactured by gravity casting.

[0003] In the gravity casting process, the casting sand mold needs to be tilted first and the molten aluminum needs to be introduced into the intermediate receiving box. Then, while controlling the level of the casting sand mold, the molten aluminum in the intermediate receiving box automatically flows into the casting sand mold and finally cools and forms the gear chamber cover. Gravity casting can reduce the height of the molten aluminum pouring, reduce the impact of the molten aluminum on the relevant structures inside the casting sand mold, and ensure the quality of the final product.

[0004] However, using the above method, a small amount of molten aluminum will inevitably remain in the intermediate containment box. After the molten aluminum solidifies, it forms a solid aluminum shell inside the intermediate containment box, which requires on-site personnel to manually clean it regularly. This increases the workload of on-site personnel and also poses a risk of inhaling toxic gases and injury. Especially for gear chamber covers with large size ranges, manual cleaning by personnel is more difficult, riskier, and less efficient. Summary of the Invention

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] This intelligent casting island is specifically designed for sand casting of automotive engine gear chamber covers, realizing integrated operations of casting, part removal, and cleaning. Its core objective is to improve casting efficiency and product qualification rate while reducing manual intervention.

[0029] See attached document Figure 1 - Appendix Figure 9 A smart casting island for casting gear chamber covers includes a casting body 300 and a hoisting device 100 located outside the casting body 300. The casting body 300 casts the gear chamber cover. After the cast gear chamber cover cools and solidifies, the hoisting device 100 lifts, transports, and stacks the corresponding gear chamber cover, thereby achieving continuous and efficient production of gear chamber covers.

[0030] The casting body 300 includes a casting base 310, a casting sand mold 330, and a tilting shaft 320 located between the two. The tilting shaft 320 can control the casting sand mold 330 to tilt in a predetermined direction or adjust it to a horizontal state. It also includes an intermediate receiving device 400 located on the upper side of the casting sand mold 330. The intermediate receiving device 400 is connected to the bottom of the casting sand mold 330 through a positioning mechanism 700. The intermediate receiving device 400 can move synchronously with the casting sand mold 330 to ensure that the molten aluminum can flow normally and stably between the two.

[0031] The intermediate receiving device 400 includes an intermediate positioning frame 430 and intermediate receiving boxes 440 located on both sides of the intermediate positioning frame 430. The intermediate positioning frame 430 is connected to the positioning mechanism 700 via a rotating shaft 420. By rotating the rotating shaft 420, the intermediate positioning frame 430 can be controlled to drive the intermediate receiving boxes 440 on both sides to deflect horizontally around a predetermined vertical axis.

[0032] An automatic cleaning device 500 is provided on the side of the intermediate receiving device 400 away from the casting sand mold 330. The automatic cleaning device 500 can automatically clean the aluminum shell remaining in the intermediate receiving box 440 of the intermediate receiving device 400 without manual intervention.

[0033] Specifically, the automatic cleaning device 500 includes a cleaning end 510, a control component for controlling the deflection of the cleaning end 510, and an electric slide rail 560 for controlling the movement of the cleaning end 510 along the length of the intermediate receiving box 440. The control component can adjust the deflection state of the cleaning end 510, and the electric slide rail 560 can control the position of the cleaning end 510. The two work together to drive the cleaning end 510 to complete the cleaning of the surface of the intermediate receiving box 440.

[0034] During the automatic cleaning process, the intermediate receiving box 440 is first rotated 180° by rotating the rotating shaft 420. Then, the cleaning end 510 is controlled to fit against the surface of the intermediate receiving box 440 by the control component to complete the automatic cleaning. During the cleaning process, the cleaning end 510 is controlled to move along the length of the intermediate receiving box 440 by the electric slide rail 560 to achieve deep cleaning of various positions inside the intermediate receiving box 440.

[0035] The casting body 300 is the core equipment for sand casting. The outer edge of the casting base 310 is made of cast iron, and the middle can be used to place the sand core. The internal structure of the casting sand mold 330 is precisely made according to the three-dimensional model of the gear chamber cover, with a cavity size accuracy of ±0.1mm, ensuring that the casting size meets the standard. The rotating shaft 320 is driven by a servo motor, and the rotation angle is adjustable from 0-90°. It can drive the casting sand mold 330 to rotate to receive and pour molten aluminum.

[0036] The intermediate receiving device 400 is located in the middle to receive molten aluminum to ensure the normal operation of gravity casting. The intermediate positioning frame 430 is made of heat-insulating material. The intermediate receiving boxes 440 on both sides are arc-shaped grooves with length dimensions that match the shape of the gear chamber cover to ensure that the molten aluminum can flow evenly from multiple positions into the casting sand mold 330. The rotating shaft 420 is connected to the servo motor assembly 410 to realize drive control.

[0037] The automatic cleaning device 500 is the core cleaning component, which can drive the cleaning end 510 to move along the length of the intermediate receiving box 440 to achieve full surface cleaning of the solid substances remaining on the inner surface of the intermediate receiving box 440; the control component can be a motor-driven deflection mechanism with a deflection angle of 0-90° to ensure that the cleaning end 510 is in close contact with the surface of the casting and to ensure the stable operation of the rotational friction cleaning.

[0038] After the solidified molten aluminum residue accumulates to a certain thickness in the intermediate receiving box 440, the rotating shaft 420 drives the intermediate positioning frame 430 and the intermediate receiving boxes 440 on both sides to rotate horizontally and change direction. This allows the cleaned intermediate receiving box 440 to be rotated to the side of the casting sand mold 330, enabling continuous reception and transfer of molten aluminum. Meanwhile, the intermediate receiving box 440 to be cleaned is rotated to the side away from the casting sand mold 330. At this time, the automatic cleaning device 500 can perform friction cleaning on the surface of the intermediate receiving box 440 to achieve automated cleaning without manual intervention. This ensures that the molten aluminum can be received and transferred normally afterward, and prevents the continuous increase in the thickness of the aluminum shell from affecting the subsequent reception and transfer of molten aluminum.

[0039] In summary, the above structural design enables automatic casting and deep cleaning of gear chamber covers and related structural components. During the continuous production of gear chamber covers, it improves the overall automation rate of the production process, reduces the workload of workers, and greatly improves the efficiency of gear chamber cover casting. Furthermore, it eliminates the need for workers to approach for cleaning, avoiding the inhalation of toxic and harmful gases and reducing the risk of injury to surrounding workers. It is especially suitable for gear chamber covers with large size ranges.

[0040] An air-jet cleaning body 200 is also provided on the outside of the casting body 300. The air-jet cleaning body 200 is located on the outside of the rotation path of the casting sand mold 330. The air-jet cleaning body 200 is used to clean the residual sand on the surface of the sand core inside the casting sand mold 330 to prevent residual sand from affecting the casting quality. It is located on the outside of the turning path of the casting sand mold 330. When the casting sand mold 330 turns to the predetermined tilt position, the air-jet cleaning body 200 is activated. At this time, the cavity opening faces outward to facilitate the discharge of sand particles. After the inside of the sand core is cleaned, molten aluminum is added into the intermediate receiving box 440 on the side near the casting sand mold 330 to realize the addition of molten aluminum.

[0041] The jet pressure of the jet cleaning unit 200 is controlled at 0.6-0.8MPa, and the air source is dry compressed air to avoid the sand mold from getting damp and clumping. The cleaning time is determined according to the amount of residual sand particles on the surface of the sand core inside the sand mold to ensure that there are no residual sand particles inside the cavity. After cleaning, the amount of residual sand in the sand mold cavity is ≤0.5g.

[0042] Specifically, the jet cleaning body 200 includes a multi-joint manipulator 230 and a jet pipe 210. The jet pipe 210 and the multi-joint manipulator 230 are connected by a universal joint 220. Through the cooperation of the multi-joint manipulator 230 and the universal joint 220, the casting sand mold 330 and the intermediate receiving box 440 can be cleaned at different stages. Before the aluminum molten metal is poured, the jet pipe 210 is controlled to face the casting sand mold 330 to clean the sand particles. After the intermediate receiving box 440 is cleaned, the jet pipe 210 is controlled to face the outer side of the intermediate receiving box 440 to achieve automatic deep cleaning of residual aluminum shell debris.

[0043] The multi-joint robotic arm 230 is a multi-axis industrial robot that can flexibly adjust the position and angle of the air jet pipe 210 to adapt to the complex structure of the casting sand mold 330 cavity (such as deep cavities and blind holes), achieving thorough cleaning. The air jet pipe 210 is a stainless steel flexible hose with a flat nozzle at the end, causing the airflow to be sprayed out in a fan shape, expanding the cleaning range. The universal joint 220 is a 360° rotating joint, which can allow the air jet pipe 210 to deflect at any angle. Together with the multi-joint robotic arm 230, it can penetrate deep into the cavity to remove residual sand particles. The air jet pipe 210 is connected to an external high-pressure air source and is equipped with a flow control valve, which can adjust the air jet flow rate according to the degree of sand mold contamination.

[0044] Specifically, the positioning mechanism 700 includes a first positioning base 730 fixedly connected to the casting sand mold 330 and a second positioning body 710 fixedly connected to the intermediate receiving device 400. The first positioning base 730 and the second positioning body 710 are connected by a positioning telescopic rod 720.

[0045] The positioning mechanism 700 is used to fix the relative position of the intermediate receiving device 400 and the casting sand mold 330, ensuring that the molten aluminum can flow accurately and stably from the intermediate receiving box 440 into the casting sand mold 330. The first positioning base 730 is fixed to the bottom of the casting sand mold 330 by bolts to ensure the connection strength. The positioning telescopic rod 720 is a servo electric push rod or a hydraulic telescopic rod, which can control the intermediate receiving device 400 to move linearly in a predetermined direction, so that the intermediate receiving box 440 is aligned with or away from the opening of the casting sand mold 330, with an alignment deviation ≤1mm.

[0046] The bottom of the intermediate receiving box 440 is provided with a first wedge-shaped sealing surface on the side away from the rotating shaft 420, and the top of the casting sand mold 330 is provided with a second wedge-shaped sealing surface. During the movement, the intermediate receiving box 440 is first controlled to move away from the casting sand mold 330, and after being staggered by a certain distance, the intermediate receiving box is controlled to rotate 180° to avoid the two wedge-shaped sealing surfaces interfering with each other.

[0047] Both the first and second wedge-shaped sealing surfaces are inclined at 45-60°. When the intermediate receiving device 400 moves to the receiving position, the two wedge-shaped surfaces fit tightly together to form a sealing structure with a sealing gap ≤0.1mm. This sealing structure prevents aluminum leakage and loss, while also preventing air from entering the mold cavity and affecting the casting quality. The wedge-shaped surfaces are made of wear-resistant alloy material, extending their service life. When the aluminum is poured, a certain pre-tightening force is applied through the positioning telescopic rod 720 to ensure reliable sealing and prevent loosening.

[0048] The automatic cleaning device 500 also includes an impact rod 520 and an impact telescopic rod 530 for controlling the reciprocating movement of the impact rod 520. The telescopic end of the impact telescopic rod 530 is fixedly connected to the impact rod 520, and the base of the impact telescopic rod 530 is connected to the electric slide rail 560 through a positioning bracket 550.

[0049] The impact rod 520 has a cylindrical structure. The impact telescopic rod 530 drives the impact rod 520 to rapidly reciprocate, causing residual solid impurities on the surface of the intermediate receiving box 440 to fall off under the impact force. The bottom of the positioning bracket 550 is fixedly connected to the electric slider of the electric slide rail 560 to ensure that the impact telescopic rod 530 is stably installed without shaking during impact. The impact force of the impact rod 520 can be adjusted and controlled by the impact telescopic rod 530, flexibly adapting to the thickness and material of the casting.

[0050] The aforementioned impact is carried out before the molten aluminum is poured into the casting sand mold 330 and is relatively stable and not yet completely solidified. Appropriate impact can also impact the molten aluminum in the casting sand mold 330, ensuring that the molten aluminum can efficiently penetrate into every corner of the casting sand mold 330, reducing the impact of residual air bubbles on the final product's appearance quality, and improving the product's appearance quality; at the same time, the impact force should not be too large to affect the stability and state of the sand core.

[0051] Specifically, the cleaning end 510 includes a hollow cleaning ring, which is sleeved on the outside of the impact rod 520. A drive assembly for controlling the rotation of the cleaning ring is also provided between the cleaning ring and the impact rod 520. The cleaning end 510 can be controlled to rotate through the drive assembly. During the rotation, the cleaning end 510 can increase the friction on the aluminum shell inside the intermediate receiving box 440, thereby achieving rapid cleaning of impurities in the aluminum shell inside the intermediate receiving box 440.

[0052] The cleaning ring has a ring-shaped structure with a metal cleaning brush mounted on its surface. This structure enables a combined cleaning process of impact and brushing, improving cleaning efficiency by 40% compared to single impact cleaning. The metal cleaning brush of the cleaning ring is made of a wear-resistant material with moderate hardness, effectively removing residual aluminum shell inside the central receiving box 440 without scratching its inner surface. The drive assembly provides rotational power for cleaning, creating dynamic friction between the brush bristles and the casting surface, further enhancing the cleaning effect.

[0053] Specifically, the drive assembly includes a drive protrusion 511 fixedly connected to the inner wall of the cleaning ring, and a drive groove 521 adapted to the drive protrusion 511 is provided on the outer side of the impact rod 520. The base of the cleaning ring and the impact telescopic rod 530 are rotatably connected by a limiting frame 540. The limiting frame 540 can position the rotation position of the cleaning end 510, ensuring that the cleaning end 510 can rotate back and forth in a predetermined position, thus ensuring stable cleaning.

[0054] During the reciprocating extension and retraction of the impact rod 520 controlled by the impact telescopic rod 530, the fixed drive protrusion 511 inside the clearing ring can move along the inner wall of the arc-shaped drive groove 521. The impact rod 520 and the drive groove 521 are in a relatively fixed state. At this time, the drive protrusion 511 can drive the outer cleaning ring to reciprocate synchronously with the arc-shaped drive groove 521, thereby realizing automatic drive control.

[0055] The aforementioned drive groove 521 has a small inclination arc to avoid excessive pressure and friction between the drive protrusion 511 and the drive groove 521. At the same time, rolling structures such as balls can be set on the surface of the drive protrusion 511 to further reduce rolling friction.

[0056] The impact rod 520 can reciprocate along the axial direction under the action of the impact telescopic rod 530 to achieve impact. During the reciprocating linear movement of the impact rod 520, it can drive the cleaning end 510 to rotate back and forth in a relatively constant position. The two work together to achieve efficient cleaning of the intermediate receiving box 440. At the same time, there is no need to arrange multiple drive units and control electrical components for individual control. The two actions are automatically synchronized and end, which simplifies the cleaning control method and greatly improves the overall cleaning efficiency and effect.

[0057] When the impact telescopic rod 530 drives the impact rod 520 to reciprocate, the driving protrusion 511 slides within the arc-shaped drive groove 521, generating a circumferential force that compresses and cleans the ring, causing it to reciprocate around the axis of the impact rod 520. The reciprocating deflection speed is linked to the reciprocating speed of the impact rod 520. The limiting bracket 540 is a ring bearing structure, fixed to the base of the impact telescopic rod 530, which both restricts the axial movement of the cleaning ring and ensures its smooth rotation, reducing frictional resistance.

[0058] Below the automatic cleaning device 500, a collection device 600 is also provided. The collection device 600 can collect the impurities that fall into the intermediate container box 440, preventing the impurities from overflowing and affecting the surrounding equipment, and ensuring the cleanliness of the area around the production equipment.

[0059] Furthermore, a cooling medium spraying assembly 570 is also provided on the outside of the impact telescopic rod 530. The cooling medium spraying assembly 570 includes a spraying rod 572 located on the horizontal side of the cleaning ring, and a pumping pipe 571 connected to the spraying rod 572. The cooling medium is pumped in from the pumping pipe 571. The cooling medium spraying assembly 570 can spray out a small amount of cooling medium to briefly cool the aluminum shell on the surface of the intermediate container box 440. It can further reduce the adhesion effect of the aluminum shell on the inner wall surface of the intermediate container box 440 by utilizing the principle of thermal expansion and contraction. Together with the cleaning end 510, it can improve the cleaning effect on the aluminum shell inside the intermediate container box 440.

[0060] The cooling medium can be either a cooling liquid or a cooling gas. During the process of spraying the cooling medium, the spray rod 572 is in contact with the surface of the intermediate receiving box 440. Multiple nozzles are arranged along the length of the spray rod 572 to spray the cooling medium synchronously.

[0061] Furthermore, the impact telescopic rod 530 is equipped with a control piston inside, which divides the impact telescopic rod 530 into a first control chamber and a second control chamber. The first control chamber is connected to a pressure controller, and the second control chamber is equipped with an elastic airbag. The elastic airbag is connected to two pumping pipes with built-in one-way valves. The two pumping pipes are respectively connected to the ejection rod 572 and the pumping pipe 571.

[0062] The control piston can be made of wear-resistant rubber and is sealed to the inner wall of the impact telescopic rod 530. The first control chamber is connected to an external pressure controller and the control piston is driven to move back and forth by changes in air pressure, thereby driving the impact rod 520 to perform impact operations.

[0063] The elastic airbag in the second control chamber can be made of fluororubber, which is oil-resistant and temperature-resistant, and can be repeatedly compressed and expanded as the control piston moves: when the control piston moves to the right, the elastic airbag is compressed, the internal pressure increases, and the cooling medium is pumped to the spray bar 572 through one of the pumping pipes (with a built-in one-way valve that only allows the medium to flow out) to achieve atomized spraying.

[0064] When the control piston returns to its original position to the left, the elastic airbag expands and returns to its original position under its own elasticity, and draws in the cooling medium from the pump inlet pipe 571 through another pumping pipe (with a built-in check valve that only allows the medium to flow in), thus completing the medium replenishment.

[0065] This structure eliminates the need for additional power to drive the cooling medium pump. It utilizes the reciprocating motion of the impact telescopic rod 530 to achieve synchronous pumping, simplifying the equipment structure, reducing energy consumption, and linking the pumping flow rate with the impact frequency. This ensures precise matching between the cooling effect and the cleaning rhythm. Furthermore, it can periodically and intermittently spray the cooling medium, preventing the continuous spraying of the cooling medium from creating a directional airflow that carries away impurities during cleaning. This also prevents impurities from overflowing onto the casting sand mold 330 side during the cleaning process, ensuring the quality of the final product.
