Description

Technical Field

[0001] This utility model relates to the field of clay sand box turning technology, and in particular to a turning and closing device for a fully automatic horizontal molding line for clay sand. Background Technology

[0002] In the casting production of cast iron parts such as forklift wheel hubs and brake hubs, clay sand molding is mainly used. The design of upper and lower molds is adopted. The upper and lower molds are molded and then joined together to form the mold box through a fully automatic horizontal clay sand molding line. Turning the mold box over is a key process before closing the mold box, which directly affects the forming quality and production efficiency of the cast iron parts. At present, there are still many shortcomings in the clay sand mold box turning and closing device.

[0003] The clay sand box turning and closing device suffers from insufficient automation. The turning process often requires manual assistance in positioning or intervention, which not only increases the labor intensity of workers but also poses safety hazards due to operational errors. Traditional devices lack effective automatic limit mechanisms when turning sand boxes, making the sand boxes prone to displacement or even falling due to centrifugal force, resulting in decreased closing accuracy and affecting the stability of casting quality. The transmission structure design of some devices is not reasonable enough, and the turning angle control accuracy is insufficient, which can easily lead to reverse reversal or jamming. It is difficult to adapt to the continuous operation requirements of fully automated horizontal molding lines and restricts the improvement of overall production efficiency.

[0004] In response to the technical problems of low automation, easy displacement of sand boxes during flipping, and insufficient operational accuracy and efficiency, this application proposes a flipping and closing device for a fully automatic horizontal molding line for clay sand. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a fully automatic horizontal molding line for clay sand, which realizes the automated and precise operation of the sand box turning process. During the turning process, it can automatically limit the sand box to prevent displacement without manual intervention, which not only ensures the safety of operation, but also improves the accuracy and efficiency of operation.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A fully automatic horizontal molding line for clay sand, comprising a support frame, with a first rotating wheel rotatably connected to the inner sides of the front and rear ends of the support frame, a first gear fixedly connected to the opposite side of the first rotating wheel, and a second rotating wheel fixedly connected to the opposite side of the first gear. A dust cover is fixedly connected to the lower left side of the support frame, and a drive shaft is rotatably connected to the front and rear sides of the dust cover. A second gear is fixedly connected to the front and rear ends of the drive shaft, with the outer side of the second gear meshing with the outer side of the first gear. Connectors are fixedly connected to the opposite sides of the left and right ends of the second rotating wheel, with a plurality of conveying wheels arranged inside the connectors, and an outer frame arranged inside the conveying wheels. Limiting components are provided on the inner sides of both the front and rear ends of the connectors.

[0008] Furthermore, the limiting assembly includes a limiting rod slidably connected to the inner sides of both the front and rear ends of the connector, a buckle fixedly connected to the outer end of the limiting rod, a spring provided on the outer side of the limiting rod, a limiting ring fixedly connected to the outer side of the limiting rod outside the spring, a fixing ring fixedly connected to the inner sides of both the front and rear ends of the bracket, slots provided at both the left and right ends of the fixing ring, and the buckle provided inside the slot.

[0009] Furthermore, the inner end of the spring is fixedly connected to the inside of the connector, the outer end of the spring is fixedly connected to the inner end of the limiting ring, and the limiting ring is slidably connected to the inner side of the connector.

[0010] Furthermore, the outer side of the second rotating wheel is rotatably connected to the inner side of the bracket, and the outer side of the fixing ring is located on the opposite side of the second rotating wheel.

[0011] Furthermore, a motor is fixedly connected inside the dust cover, and a worm gear is fixedly connected to the drive end of the motor.

[0012] Furthermore, a turbine is fixedly connected to the middle of the drive shaft, and the outer side of the worm gear is engaged with the outer side of the turbine.

[0013] Furthermore, conveyor belts are provided at both the front and rear ends of the first rotary wheel, and an outer frame is slidably connected to the inner side of the conveyor belts.

[0014] Furthermore, a number of reinforcing members are fixedly connected to the inner side of the outer frame, and an inner frame is fixedly connected to the inner side of the reinforcing members.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, through the coordinated work of limiting rods and buckles, the buckles are squeezed by the fixed ring when flipping, which drives the limiting rod to slide inward, stably restricting the movement of the outer frame and preventing the sand box from shifting and falling due to centrifugal force. After it is in place, the spring pushes the limiting ring to reset, and the buckle is automatically released from the restriction when it is engaged in the slot. No manual operation is required, which not only ensures the safety of operation, but also improves the accuracy and automation of flipping and closing the box.

[0017] 2. In this utility model, a worm gear driven by a motor meshes with a turbine, and gear transmission is combined to achieve precise action, ensuring accurate tilting angle without reverse rotation. Gear meshing ensures synchronous rotation of the rotating wheel, and the conveyor belt and conveyor wheel are seamlessly connected, realizing a smooth transition of the sand box from conveying to tilting. This adapts to continuous operation on the assembly line and improves overall operation efficiency and stability. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-3 This utility model provides an embodiment of a fully automatic horizontal molding line for clay sand, comprising a support 1. A first rotating wheel 2 is rotatably connected to the inner sides of both ends of the support 1. A first gear 4 is fixedly connected to the opposite side of the first rotating wheel 2. A second rotating wheel 3 is fixedly connected to the opposite side of the first gear 4. A dust cover 5 is fixedly connected to the lower left side of the support 1. A drive shaft 6 is rotatably connected to the front and rear sides of the dust cover 5. A motor 9 is fixedly connected inside the dust cover 5. A worm gear 10 is fixedly connected to the drive end of the motor 9. A turbine 8 is fixedly connected to the middle of the drive shaft 6. The outer side of the worm gear 10 is meshed with the outer side of the turbine 8. A second gear 7 is fixedly connected to both ends of the drive shaft 6. The outer side of the second gear 7 is meshed with the outer side of the first gear 4. (See reference) Figure 4 The left and right ends of the second rotating wheel 3 are fixedly connected to the opposite sides of the connecting parts 12. Several conveyor wheels 13 are provided on the inner side of the connecting parts 12. An outer frame 14 is provided on the inner side of the conveyor wheels 13. Conveyor belts 11 are provided at both the front and rear ends of the first rotating wheel 2. An outer frame 14 is slidably connected to the inner side of the conveyor belt 11. Several reinforcing members 15 are fixedly connected to the inner side of the outer frame 14. An inner frame 16 is fixedly connected to the inner side of the reinforcing members 15.

[0028] The worker first starts the motor 9 installed inside the dust cover 5. The dust cover 5 blocks dust from entering, reducing wear and corrosion, extending the life of the transmission system, and lowering the failure rate and maintenance frequency. Its drive end drives the worm gear 10 to rotate, and the worm gear 10 drives the turbine 8 fixedly connected in the middle of the transmission shaft 6 to rotate. This allows for precise control of the tilting angle and prevents reverse rotation due to excessive load, ensuring stable tilting action. The second gears 7 at both ends of the transmission shaft 6 rotate with the transmission shaft 6, and the outer sides of the second gears 7 are meshed with the outer sides of the first gear 4, thereby driving the first gear 4 to rotate. The first gear 4 is fixedly connected to the first gear 4. The first wheel 2 and the second wheel 3 also rotate inside the support 1. When the first wheel 2 rotates, the conveyor belts 11 at its front and rear ends transport the outer frame 14 and the reinforcing member 15 connected to its inner side and the inner frame 16 into the opposite side of the two conveyor wheels 13. The conveyor wheels 13 are connected to a drive source. The reinforcing member 15 and the inner frame 16 form a high-strength structure to extend the service life of the device, reduce maintenance costs, realize a seamless transition from conveying to flipping of the sand box, adapt to continuous operation of the assembly line, reduce process connection time, and improve efficiency. When flipping the box, the second wheel 3 drives the conveyor wheel 13 and the outer frame 14 to flip 180° synchronously through the connecting member 12.

[0029] Reference Figures 4-6 The limiting assembly includes a limiting rod 17 slidably connected to the inner sides of both the front and rear ends of the connector 12. A buckle 18 is fixedly connected to the outer end of the limiting rod 17. A spring 19 is provided on the outer side of the limiting rod 17. A limiting ring 20 is fixedly connected to the outer side of the limiting rod 17 and the outer side of the spring 19. A fixing ring 21 is fixedly connected to the inner sides of both the front and rear ends of the bracket 1. A slot 22 is provided on both the left and right ends of the fixing ring 21. The buckle 18 is provided on the inner side of the slot 22. The inner end of the spring 19 is fixedly connected to the inside of the connector 12. The outer end of the spring 19 is fixedly connected to the inner end of the limiting ring 20. The limiting ring 20 is slidably connected to the inner side of the connector 12. The outer side of the second rotating wheel 3 is rotatably connected to the inner side of the bracket 1. The outer side of the fixing ring 21 is provided on the opposite side of the second rotating wheel 3.

[0030] During the flipping process, the buckle 18 connected to the rear end of the limiting rod 17 is squeezed by the fixing ring 21, causing the limiting rod 17 to slide inward, thereby restricting the movement of the outer frame 14 and preventing the sand box from shifting or falling due to centrifugal force, ensuring safety. When the flipping is in place, under the elastic force of the spring 19, the limiting ring 20 moves outward, driving the limiting rod 17 and the buckle 18 connected to its outer end to move outward, so that the buckle 18 moves to the inside of the slot 22, thereby releasing the limiting rod 17 from restricting the outer frame 14, automatically releasing the limit without manual intervention, improving the degree of automation, and ensuring the accuracy of flipping and closing the box.

[0031] Working principle: When the equipment is running, the motor 9 inside the dust cover 5 is started. Its drive end drives the worm gear 10 to rotate. The worm gear 10 drives the turbine 8 fixedly connected in the middle of the transmission shaft 6 to rotate. The second gears 7 at both ends of the transmission shaft 6 rotate with the transmission shaft 6, and the outer side of the second gear 7 meshes with the outer side of the first gear 4, thereby driving the first gear 4 to rotate. The first rotating wheel 2 and the second rotating wheel 3 fixedly connected to the first gear 4 also rotate inside the bracket 1. When the first rotating wheel 2 rotates, the conveyor belts 11 at both ends of it transport the outer frame 14 and the reinforcing member 15 connected to its inner side to the inner frame 14. When frame 16 enters the opposite side of the two conveyor wheels 13, during the flipping process, the second rotating wheel 3 drives the conveyor wheels 13 and the outer frame 14 to flip synchronously through the connector 12. During the flipping process, the buckle 18 connected to the rear end of the limiting rod 17 is squeezed by the fixing ring 21, causing the limiting rod 17 to slide inward, thereby restricting the movement of the outer frame 14. When the flipping is in place, under the elastic force of the spring 19, the limiting ring 20 moves outward, driving the limiting rod 17 and the buckle 18 connected to its outer end to move outward, so that the buckle 18 moves to the inside of the slot 22, thereby releasing the limiting rod 17 from restricting the outer frame 14.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
