Description

Technical Field

[0001] This utility model relates to the field of casting and pouring technology, specifically a combined bottom pouring device. Background Technology

[0002] In casting production, the bottom pouring device is a key piece of equipment that connects molten metal to the mold, and its performance directly affects the quality of castings and production efficiency.

[0003] Existing bottom-pouring casting devices often suffer from low automation. Most devices rely on manual operation for ladle tilting and flow rate adjustment, which is not only labor-intensive but also results in poor operational consistency and fluctuations in casting quality due to human error. Furthermore, most bottom-pouring casting devices lack precise flow rate control mechanisms, making it difficult to stably control the outflow velocity and flow rate of the molten metal, often leading to inconsistent flow rates that affect the quality of the casting. Moreover, the insufficient precision in the fit between the outlet and valve core of most bottom-pouring casting devices causes splashing of the molten metal upon impact, resulting in material waste and safety hazards. Therefore, we propose a combined bottom-pouring casting device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low automation, poor flow control, and easy splashing during pouring in existing devices.

[0005] The specific solution of this utility model is as follows: A combined bottom-pouring casting device is designed, comprising two symmetrically arranged supports. The lower surfaces of the two supports are fixedly connected to the same base. The inner walls of the two supports are rotatably connected to the same pouring ladle. The inner wall of the pouring ladle is fixedly connected to two symmetrically arranged internal gear rings. The inner walls of the two internal gear rings are meshed with gears. The inner wall of the gear on the right side is fixedly connected to a first pulley. The upper surface of the base is fixedly connected to a motor. The output end of the motor is fixedly connected to a second pulley. The surface of the second pulley and the surface of the first pulley are fitted with the same transmission belt. The upper surface of the base is fixedly connected to a sliding rod. The sliding rod is located on the left side of the support. The inner wall of the sliding rod is slidably connected to a first slider. The inner wall of the first slider is rotatably connected to a lead screw.

[0006] In specific implementation, the lower end of the lead screw is rotatably connected to the upper surface of the base, the upper end of the lead screw passes through the upper surface of the slide bar and extends upward, the upper end of the lead screw is fixedly connected to a first bevel gear, and the inner wall of the gear on the left side is fixedly connected to a second bevel gear, the surface of the second bevel gear meshing with the surface of the first bevel gear.

[0007] In specific implementation, the side walls of the two supports are fixedly connected to the same hopper, the inner wall of the hopper is fixedly connected to a pouring hopper, the inner wall of the pouring hopper is fixedly connected to a fixing plate, the lower end of the pouring hopper is provided with a conical discharge port, a conical valve core is provided above the conical discharge port, the upper end of the conical valve core is fixedly connected to a valve core push rod, and the upper end of the valve core push rod penetrates the upper surface of the fixing plate and extends upward.

[0008] In a specific implementation, a connecting rod is fixedly connected to the upper end of the valve core push rod. The connecting rod is arranged parallel to the fixing plate. The other end of the connecting rod is rotatably connected to a first rotating rod. The other end of the first rotating rod is rotatably connected to the side wall of the adjacent bracket.

[0010] In practice, both the conical valve core and the valve core push rod are made of tungsten alloy, and the taper of the conical valve core matches the taper of the conical discharge port.

[0011] The beneficial effects of this utility model are as follows: This utility model achieves ladle tilting through a linkage structure of motor-driven pulley, gear and internal gear ring. Then, through a multi-stage transmission mechanism composed of bevel gear, lead screw, slider and rotating rod, the tilt angle of the ladle is converted into the lifting and lowering motion of the conical valve core. The opening and closing degree of the conical discharge port can be precisely adjusted to achieve stepless control of the pouring flow rate and adapt to the flow requirements of different castings. This invention, through the matching taper design of the conical discharge port and the conical valve core, forms a smooth streamlined channel when the molten metal flows out, reducing the impact force of the liquid flow and minimizing splashing from gaps. At the same time, the design of the pouring hopper also prevents molten metal from splashing, greatly improving the safety of the pouring process and the utilization rate of raw materials.

[0013] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0014] Example 1 A combined bottom-pouring casting device, see Figures 1 to 3 The design includes two symmetrically arranged supports 1. The lower surfaces of the two supports 1 are fixedly connected to the same base 2. The inner walls of the two supports 1 are rotatably connected to the same casting ladle 3. The inner walls of the casting ladle 3 are fixedly connected to two symmetrically arranged internal gear rings 4. The inner walls of the two internal gear rings 4 are meshed with gears 5. The inner wall of the right gear 5 is fixedly connected to a first pulley 6. The upper surface of the base 2 is fixedly connected to a motor 7. The output end of the motor 7 is fixedly connected to a second pulley 8. The surface of the second pulley 8 and the surface of the first pulley 6 are fitted with the same transmission belt 9. The upper surface of the base 2 is fixedly connected to a sliding rod 10. The sliding rod 10 is located on the left side of the support 1. The inner wall of the sliding rod 10 is slidably connected to a first slider 11. The inner wall of the first slider 11 is rotatably connected to a lead screw 12.

[0015] The lower end of the lead screw 12 is rotatably connected to the upper surface of the base 2, and the upper end of the lead screw 12 passes through the upper surface of the slide bar 10 and extends upward. The upper end of the lead screw 12 is fixedly connected to the first bevel gear 13, and the inner wall of the left gear 5 is fixedly connected to the second bevel gear 14. The surface of the second bevel gear 14 meshes with the surface of the first bevel gear 13. Through the meshing transmission of the first bevel gear 13 and the second bevel gear 14, the rotation of the gear is converted into the rotation of the lead screw 12, thereby realizing the automatic linkage of the tilting of the ladle 3 and the flow rate adjustment.

[0016] The side walls of the two supports 1 are fixedly connected to the same hopper 15. The inner wall of the hopper 15 is fixedly connected to the pouring hopper 16. The inner wall of the pouring hopper 16 is fixedly connected to the fixing plate 17. The lower end of the pouring hopper 16 is provided with a conical discharge port 18. A conical valve core 19 is provided above the conical discharge port 18. A valve core push rod 20 is fixedly connected to the upper end of the conical valve core 19. The upper end of the valve core push rod 20 passes through the upper surface of the fixing plate 17 and extends upward. By setting the conical valve core 19, a smooth streamlined channel is formed when the molten metal flows out, reducing the pouring impact force.

[0017] A connecting rod 21 is fixedly connected to the upper end of the valve core push rod 20. The connecting rod 21 is arranged parallel to the fixed plate 17. The other end of the connecting rod 21 is rotatably connected to the first rotating rod 22. The other end of the first rotating rod 22 is rotatably connected to the side wall of the adjacent bracket 1. Through the rotatable connection structure between the connecting rod 21 and the first rotating rod 22, the lifting and lowering of the valve core push rod 20 is made more stable, avoiding flow fluctuations and splashing caused by the shaking of the conical valve core 19.

[0018] The surface of the first rotating rod 22 is slidably connected to the second slider 23, and the side wall of the second slider 23 is rotatably connected to the second rotating rod 24. The other end of the second rotating rod 24 is rotatably connected to the side wall of the first slider 11. Through the sliding transmission design of the second slider 23 and the second rotating rod 24, the tilt angle of the ladle 3 is timely fed back to the height adjustment of the conical valve core 19.

[0019] Both the conical valve core 19 and the valve core push rod 20 are made of tungsten alloy. The taper of the conical valve core 19 matches the taper of the conical discharge port 18. By using the conical valve core 19 and the valve core push rod 20 made of tungsten alloy, the long-term use and fitting accuracy of the equipment structure under harsh high-temperature conditions are guaranteed.

[0020] During operation, the output of motor 7 drives the second pulley 8 to rotate, which is transmitted to the first pulley 6 via transmission belt 9, causing the right gear 5 to rotate synchronously. Gear 5 meshes with the internal gear ring 4 on the inner wall of ladle 3, driving ladle 3 to rotate along support 1, thus achieving automated tilting. Simultaneously, the tilting of ladle 3 drives the left gear 5 to rotate, and the second bevel gear 14 connected to the left gear 5 drives the meshing first bevel gear 13 to rotate, thus rotating the lead screw 12. The rotation of lead screw 12 drives the first slider 11 to move up and down. When ladle 3 begins to tilt, it interacts with the first... The second rotating rod 24, which is rotatably connected to the slider 11, drives the first rotating rod 22 to rotate downward. The connecting rod 21, which is rotatably connected to the first rotating rod 22, drives the valve core push rod 20 to move downward. The greater the tilting angle of the ladle 3, the smaller the flow channel of the conical valve core 19 and the conical discharge port 18. When the ladle 3 rotates, the flow channel of the conical valve core 19 and the conical discharge port 18 becomes larger, thereby ensuring that the flow rate of the pouring is consistent. The pouring hopper 3 and the conical discharge port 18 prevent splashing of molten metal and splashing from gaps during the pouring process, ensuring operational safety and reducing material waste.
