Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal smelting technology, specifically to a molten block ejector. Background Technology
[0002] In industrial production, especially in the fields of metal smelting and processing, molten iron often accumulates as a surplus or due to malfunctions. This molten iron is usually poured into iron molds, where it solidifies to form blocks known as "molten ingots." In subsequent production processes, these molten ingots need to be removed from the molds.
[0003] However, the removal process of the fused block currently faces significant challenges. Because the fused block is in close contact with the sides and bottom of the mold during solidification, the adhesion between them, and the potential for minor deformation leading to interlocking, make removal extremely difficult. Traditional removal methods rely heavily on manual labor, incurring substantial labor and time costs, and are inefficient. Even when some companies attempt to use simple tools to assist in removal, these tools often lack specificity and expertise, failing to effectively address the issue of a firm contact between the fused block and the mold. This results in poor removal outcomes and can easily damage both the fused block and the mold, affecting the secondary use value of the fused block and the lifespan of the mold.
[0004] In order to improve production efficiency, reduce labor costs, and avoid unnecessary damage to the molten metal and iron mold, it is urgent to develop a specialized, efficient and labor-saving molten metal removal machine. Utility Model Content
[0005] The purpose of this invention is to provide a molten block ejector to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a molten block ejector, comprising a trapezoidal frame, a connecting ring fixedly installed on the upper surface of the trapezoidal frame, a hydraulic telescopic column fixedly installed through the upper surface of the connecting ring, a lifting hook rotatably adjustable on the lower surface of the hydraulic telescopic column, four lifting chains rotatably installed on the upper surface of the trapezoidal frame, an auxiliary lifting ring detachably installed between two adjacent lifting chains, and a main lifting ring connected between two auxiliary lifting rings.
[0007] Preferably, an I-shaped lifting block is fixedly installed on the lower surface of the hydraulic telescopic column, an adapter seat is rotatably installed on the outer surface of the I-shaped lifting block, an installation groove is opened on the lower surface of the adapter seat, and the upper end of the lifting hook is rotatably installed in the installation groove.
[0008] Preferably, each of the top ends of the lifting chain is fixedly connected to a hook, and the hook is attached to the corresponding auxiliary lifting ring.
[0009] Preferably, two reinforcing plates are fixedly installed inside the trapezoidal frame, and the lower surface of each reinforcing plate is provided with an arc-shaped portion.
[0010] Preferably, each of the reinforcing plates has an extension bracket fixedly installed on the side opposite to the hydraulic telescopic column.
[0011] Preferably, mounting holes are provided through the outer surfaces of both the reinforcing plate and the extension leg, and a bolt and nut assembly is installed between two corresponding mounting holes.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] I. During lifting, this utility model allows the trapezoidal frame to be securely placed on the iron mold barrel, and the lifting hook to be precisely hooked into the lifting ring of the molten block. The hydraulic telescopic column retracts to easily separate the molten block from the iron mold barrel. Compared to existing methods of demolding molten blocks that rely on manual labor or simple tools, this lifting machine greatly simplifies the process, improves convenience, and reduces labor costs and operational difficulty. In terms of mechanical principles, the one-time lifting method from above ensures uniform force on the molten block, fundamentally reducing damage caused by uneven force during demolding and improving the quality of the finished molten block.
[0014] II. This utility model, by creating mounting holes in the reinforcing plate, allows for the installation of extension legs when dealing with iron mold barrels of larger diameters. By installing the extension legs, the lifting machine can flexibly adjust its structure to adapt to the needs of using iron mold barrels with larger diameters. This design effectively solves the compatibility problem of the lifting machine when dealing with iron mold barrels of different specifications, significantly increasing the application range and adaptability of the lifting machine, bringing great convenience to actual operation and use, and improving work efficiency and the practicality of the equipment.

Detailed Implementation
[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] First Embodiment
[0023] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution:
[0024] A molten block ejector includes a trapezoidal frame 1. A connecting ring is fixedly installed on the upper surface of the trapezoidal frame 1. A hydraulic telescopic column 2 is fixedly installed through the upper surface of the connecting ring. A lifting hook 3 with adjustable lifting direction is installed on the lower surface of the hydraulic telescopic column 2. Four lifting chains 4 are rotatably installed on the upper surface of the trapezoidal frame 1. The four lifting chains 4 are distributed at the four corners of the upper surface of the trapezoidal frame 1 and are rotatably connected to the perforated lugs at the four corners of the upper surface of the trapezoidal frame 1. An auxiliary lifting ring 5 is detachably installed between two adjacent lifting chains 4. A main lifting ring 6 is connected between two auxiliary lifting rings 5.
[0025] When using, combine Figure 3 As shown, with the help of an external overhead crane and the main lifting ring 6, the entire hoist is lifted to the working position. Then, the trapezoidal frame 1 is placed on the opening of the iron mold barrel 8. Next, the lifting hook 3 is hooked onto the lifting ring 9 of the molten block. Then, the hydraulic telescopic column 2 is activated to retract. Through the cooperation of the lifting hook 3 and the lifting ring 9, the molten block is slightly lifted from the iron mold barrel 8, separating the molten block from the iron mold barrel 8. Then, with the help of the external overhead crane, the entire hoist is lifted, thereby removing the molten block from the iron mold barrel 8. Compared with the existing technology, the entire process of removing the molten block greatly simplifies the operation process, improves convenience, and reduces labor costs and operation difficulty.
[0026] It is worth noting that, combined with Figure 1 and Figure 2As shown, an I-shaped lifting block 21 is fixedly installed on the lower surface of the hydraulic telescopic column 2. An adapter seat 22 is rotatably installed on the outer surface of the I-shaped lifting block 21. An installation groove 221 is opened on the lower surface of the adapter seat 22. The upper end of the lifting hook 3 is rotatably installed in the installation groove 221. By rotating the I-shaped lifting block 21 and the adapter seat 22, the lifting hook 3 can be rotated circumferentially to adjust the orientation of the hook. By rotating the lifting hook 3 in the installation groove 221, the lifting hook 3 can be flipped to adjust the angle of the hook, thereby improving the convenience of the lifting hook 3 in the operation process.
[0027] Combination Figure 1 As shown, each of the top ends of the lifting chain 4 is fixedly connected to a hook 41. The hook 41 is installed in the corresponding auxiliary lifting ring 5. In actual use, the main lifting ring 6 can be directly connected to the external crane hoist for use. The lifting chain 4 can be easily separated from the auxiliary lifting ring 5 by using the hook 41 to connect with the auxiliary lifting ring 5, thereby disconnecting the trapezoidal frame 1 from the external crane hoist.
[0028] In addition, two reinforcing plates 11 are fixedly installed inside the trapezoidal frame 1, which can improve the strength of the trapezoidal frame 1;
[0029] like Figure 3 As shown, before the molten block is formed, the crossbar 10 is used to suspend the lifting ring b, so that it is shaped inside the iron mold barrel 8, and to prevent the lifting ring b from falling into the molten iron. In order to adapt to the position of the crossbar 10 and ensure that the trapezoidal frame 1 can be stably attached to the upper surface of the iron mold barrel 8, an arc-shaped part 111 is provided on the lower surface of the reinforcing plate 11. When the trapezoidal frame 1 is placed on the upper surface of the iron mold barrel 8, the crossbar 10 just passes through the arc-shaped part 111.
[0030] Second embodiment:
[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: Based on the first embodiment, an extension leg 7 structure is added to facilitate the use of the trapezoidal frame 1 to meet the needs of the iron mold barrel 8 with a larger barrel diameter.
[0032] Specifically, such as Figure 4 As shown, extension legs 7 are fixedly installed on the side of the reinforcing plate 11 away from the hydraulic telescopic column 2, which can increase the application range of the trapezoidal frame 1, thereby facilitating its use on iron mold barrels 8 with larger diameters and improving the applicability of the lifting machine.
[0033] Specifically, mounting holes 112 are provided through the outer surfaces of both the reinforcing plate 11 and the extension leg 7. A bolt and nut assembly is installed between two corresponding mounting holes 112, and the two are fixed together by the bolt and nut assembly.
