Description

Technical Field

[0001] This utility model relates to the field of mold steel production technology, specifically a high-efficiency molten iron casting car for mold steel production. Background Technology

[0002] In the production of mold steel, the casting car is a key piece of equipment for transferring molten iron from the furnace to the mold cavity and for casting. Its performance directly affects production efficiency, operational safety, and the quality of mold steel products. Currently, the casting cars used in the industry have significant shortcomings in dealing with the problem of residual molten iron dripping during casting. Most of these casting cars do not have a special structure for handling the dripping of residual molten iron at the end of the discharge nozzle. When the gap is adjusted, the flow is controlled, or the casting is completed, the residual molten iron at the end of the discharge nozzle will drip randomly without restraint. The dripping of high-temperature molten iron not only burns the workshop floor and corrodes equipment parts, increasing equipment maintenance costs, but also poses a serious safety threat to operators, easily causing burns. At the same time, the traditional equipment used by existing mold factories for casting molten iron in the production of mold steel either uses a fixed support structure, making it difficult to adjust the casting position and requiring repeated movement of heavy molds, which greatly reduces the convenience and efficiency of casting molten iron. Summary of the Invention

[0003] The main purpose of this utility model is to solve the above-mentioned existing technical problems and provide a high-efficiency molten iron casting car for mold steel production.

[0004] The specific solution of this utility model is: a high-efficiency molten iron casting car for mold steel production, including a mounting frame, the mounting frame having a gantry structure, a traveling wheel rotatably mounted at the bottom end of the mounting frame, a sleeve mounted at the top of the mounting frame, an operating rod passing through the sleeve, a casting barrel fixedly connected to one end of the operating rod, a discharge nozzle provided on one side of the casting barrel, a slag-blocking structure installed at the bottom side of the discharge nozzle, the slag-blocking structure including a slag-blocking plate, the slag-blocking plate being detachably installed at the bottom side of the discharge nozzle, the top end of the slag-blocking plate being inclined downwards towards the discharge nozzle, and the other end being hook-shaped and forming an arc-shaped groove, the arc-shaped groove being used for centralized treatment of slag.

[0005] According to the above technical solution, stability is ensured by the gantry structure, mobility is improved by the use of wheels and push rods, and the inclined design and arc groove of the slag baffle plate are used to accurately guide and centrally treat the residual molten iron and slag. At the same time, the baffle ring prevents the operating rod from slipping, and the detachable slag baffle plate facilitates maintenance, which significantly improves the safety of casting, the cleanliness of the environment, and the purity of the mold steel products.

[0006] Furthermore, a first fixing block is installed on both sides of the slag-blocking plate, and a second fixing block is installed on the surface of the casting barrel. The first fixing block is threaded with a bolt, and the other end of the bolt is threaded with the second fixing block. The bolt is used to fix the slag-blocking plate.

[0007] According to the above technical solution, the detachable fixing is achieved by the threaded connection of the first fixing blocks on both sides, the second fixing block on the surface of the casting barrel, and the bolts. This not only ensures the stability of the slag baffle plate installation, but also facilitates quick disassembly and replacement when it is damaged by high temperature, thus improving maintenance efficiency.

[0008] Furthermore, the operating rod has a mounting groove on its surface, and a retaining ring is fitted inside the mounting groove. The retaining ring can rotate around the mounting groove and is used to limit the operating rod from sliding into the sleeve.

[0009] According to the above technical solution, the rotatable retaining ring installed in the groove on the surface of the operating rod can effectively limit the operating rod and prevent it from slipping out of the sleeve. This not only does not affect the normal rotation and adjustment of the operating rod, but also improves the stability and safety of the pouring process.

[0010] Furthermore, a push rod is installed at each end of the mounting bracket.

[0011] According to the above technical solution, the push rods at both ends of the mounting frame allow operators to easily push the pouring vehicle, flexibly adjust the pouring position, reduce the labor intensity during movement, and improve positioning efficiency and ease of operation.

[0012] Compared with the prior art, this utility model has the following advantages: The high-efficiency molten iron pouring car for mold steel production adopts a gantry frame mounting frame with bottom traveling wheels, which not only ensures the overall stability of the equipment and prevents shaking and overturning when carrying molten iron, but also facilitates flexible movement; the slag baffle plate on the bottom side of the discharge nozzle, through its inclined design and arc-shaped groove, can prevent residual molten iron from dripping randomly, reduce damage to the workshop environment and equipment, reduce the impact of impurities, and ensure the quality of mold steel. Moreover, the slag baffle plate can be detached and installed by bolts and fixing blocks, which facilitates quick replacement, simplifies maintenance, and ensures uninterrupted production; the retaining ring on the operating rod can prevent it from slipping off the sleeve, enhancing the stability and safety of operation; the push rods at both ends of the mounting frame make movement and positioning more convenient, reduce labor intensity, improve operating efficiency, and can flexibly adapt to the adjustment needs of the pouring position during production.

[0018] See Figure 1-4 This embodiment is a high-efficiency molten iron casting car for mold steel production, including a mounting frame 1. The mounting frame 1 has a gantry structure. The bottom end of the mounting frame 1 is rotatably mounted with a traveling wheel 2. The top of the mounting frame 1 is mounted with a sleeve 3. An operating rod 4 passes through the sleeve 3 and is rotatably connected. One end of the operating rod 4 is fixedly connected to a casting tank 5. A discharge nozzle 6 is provided on one side of the casting tank 5. A slag-blocking structure is installed on the bottom side of the discharge nozzle 6. The slag-blocking structure includes a slag-blocking plate 7. The slag-blocking plate 7 is detachably installed on the bottom side of the discharge nozzle 6. The top end of the slag-blocking plate 7 is inclined downwards towards the discharge nozzle 6, and the other end is hook-shaped and forms an arc-shaped groove. The arc-shaped groove is used to centrally process iron slag.

[0019] Furthermore, a first fixing block 8 is installed on both sides of the slag baffle 7, and a second fixing block 9 is installed on the surface of the casting bucket 5. The first fixing block 8 is threaded with a bolt 10, and the other end of the bolt 10 is threaded with the second fixing block 9. The bolt 10 is used to fix the slag baffle 7.

[0020] Furthermore, the operating lever 4 has a mounting groove 11 on its surface, and a retaining ring 12 is fitted inside the mounting groove 11. The retaining ring 12 can rotate around the mounting groove 11 and is used to limit the operating lever 4 from sliding into the sleeve 3.

[0021] Furthermore, a push rod 13 is installed at each end of the mounting bracket 1.

[0022] The working principle of this embodiment is as follows: When pouring is required, the operator manipulates the operating rod 4, which passes through the top sleeve 3 of the mounting frame 1, to tilt the pouring barrel 5, which is fixedly connected at one end, so that the molten iron in the barrel flows out through the discharge nozzle 6. During this process, the rotatable retaining ring 12 in the mounting groove 11 on the surface of the operating rod 4 always plays a limiting role, preventing the operating rod 4 from slipping out of the sleeve 3 and ensuring stable operation. The slag baffle 7 on the bottom side of the discharge nozzle 6 plays a key role. Its top end is designed to tilt downwards from the discharge nozzle 6, which can guide the residual molten iron and slag left in the discharge nozzle 6 during the pouring process, so that it flows along the inclined surface into the hook-shaped arc groove at the other end, realizing the centralized treatment of slag and preventing random dripping. In addition, the slag baffle 7 is securely installed through the threaded connection of the first fixing blocks 8 on both sides, the second fixing block 9 on the surface of the pouring barrel 5, and the bolts 10. When wear occurs after long-term use, it can be easily disassembled and replaced to ensure the continuous effectiveness of the slag baffle function.
