Description

Technical Field

[0001] This utility model relates to the field of steel ingot molds, and more specifically, it relates to a quick-change steel ingot mold assembly. Background Technology

[0002] In traditional steel ingot production, the ingot mold assembly plays a crucial role. Its structure is typically an integrated design of the mold body and base, or a complex connection method to fix the mold and base. This design reveals numerous problems in practical use. When the mold base is worn, deformed, or damaged and needs replacement, the process is extremely cumbersome. Taking the common bolt connection method as an example, workers need to use multiple tools and spend a significant amount of time unscrewing numerous bolts to remove the damaged base from the mold. Installing a new base requires ensuring that each bolt is precisely aligned and tightened, again consuming considerable time and manpower.

[0003] Therefore, in order to solve the above-mentioned technical problems, this application proposes a quick-change steel ingot mold assembly. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quick-change steel ingot mold assembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-change steel ingot mold assembly, comprising: The mold body has a cavity inside for holding molten steel and solidifying it into a steel ingot. A lower opening groove is provided at the bottom of the mold body, and a fixing groove is formed by extending from the two side walls of the lower opening groove to both sides. The quick-change base has support seats fixedly connected to both sides of its top. The top of the support seats is fixedly connected to a frame plate that can be inserted into the lower opening groove. The frame plate is equipped with a coupling component that can push two fixing blocks located inside the frame plate to move to both sides and insert into the fixing groove for fixation.

[0006] Preferably, the frame plate has through slots on both sides for the fixing block to pass through. The coupling assembly includes guide rails fixed on the front and rear sides of the frame plate, and sliders are slidably connected on both sides of the guide rails. A vertical plate is fixedly connected between the two sliders, and the fixing block is fixed on the opposite surface of the vertical plate and the through slot.

[0007] Preferably, each of the vertical plates is fixedly connected to a bearing seat at its bottom end, and each bearing seat is equipped with a roller bearing. Each roller bearing has a rotating rod embedded in its inner ring. Each rotating rod is fixedly connected to a screw A at the end opposite to the support seat. Each support seat and screw A has a threaded hole for threaded connection with screw A on their opposite surfaces.

[0008] Preferably, a handle is fixedly connected to the other end of each rotating rod.

[0009] Preferably, a rubber cushioning pad is installed at the bottom of the quick-change base.

[0010] Preferably, the support base and the quick-change base are detachably connected.

[0011] Preferably, a positioning block is fixedly connected to the top of the quick-change base, a positioning groove for the positioning block to be inserted is provided at the bottom of the support base, and mounting plates with through holes are fixedly connected to both sides of the support base. A screw B that can pass through the through hole is also fixedly connected to the support base, and a nut is threaded onto the outer wall of the screw B.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model, by operating the coupling component on the quick-change base, first releases the fixing of the fixing blocks, causing the two fixing blocks originally located inside the frame plate to move to both sides, thereby detaching them from the fixing grooves formed by the extension of the side walls of the bottom opening slot of the mold body. At this point, the damaged quick-change base can be easily removed from the mold body. When installing a new quick-change base, simply align the frame plate at the top of the support base on the quick-change base with the bottom opening slot of the mold body, and then operate the coupling component again to push the two fixing blocks to both sides and insert them into the fixing grooves for fixing. This achieves quick fixing of the quick-change base to the mold body. The entire process does not require complicated alignment and tedious bolt operations, and can ensure the stability of the connection, effectively solving the problem of tedious replacement of traditional mold component bases. 2. This utility model designs a detachable connection between the support base and the quick-change base. When the support base wears or deforms due to long-term support of the frame plate and bearing the weight of molten steel, or when the frame plate or coupling component at its top malfunctions and needs to be repaired or replaced, it is not necessary to disassemble and replace the entire quick-change base. Only the connection structure between the support base and the quick-change base needs to be disassembled separately, and the damaged support base and its auxiliary parts can be repaired or replaced, which greatly reduces maintenance costs. 3. The cooperation between the positioning block and the positioning groove in this utility model can quickly ensure the accurate installation position of the support base and greatly improve the efficiency of disassembly and assembly.

[0015] like Figure 1-5 As shown, this utility model provides a quick-change steel ingot mold assembly, including: The mold body 1 has a cavity inside for containing molten steel and solidifying it into a steel ingot. A lower opening groove 101 is provided at the bottom of the mold body, and fixed grooves 102 are formed extending from the two side walls of the lower opening groove 101 to both sides. The quick-change base 2 has support seats 201 fixedly connected to both sides of its top. The top of the support seats 201 is fixedly connected to a frame plate 202 that can be inserted into the lower opening slot 101. The frame plate 202 is equipped with a coupling component 204 that can push two fixing blocks 203 located inside the frame plate 202 to move to both sides and insert into the fixing groove 102 for fixation. The bottom of the quick-change base 2 is equipped with a rubber buffer pad 3. When the quick-change base 2 is assembled with the mold body 1 and placed on the ground or workbench, it can effectively buffer the impact force generated during the injection of molten steel into the cavity of the mold body 1, avoid the impact force being directly transmitted to the ground or workbench and causing the equipment to shake, and at the same time reduce the impact force on the quick-change base 2 itself and the support seats 201, frame plate 202 and other components, and extend the service life of the quick-change base 2.

[0016] When the quick-change base 2 needs to be replaced, it is not necessary to spend a lot of time disassembling it with multiple tools like the traditional bolt connection method. Instead, by operating the coupling component 204 on the quick-change base 2, the fixing block 203 is first released, so that the two fixing blocks 203 originally located inside the frame plate 202 move to both sides, thereby detaching from the fixing grooves 102 formed by the extension of the two side walls of the bottom opening groove 101 of the mold body 1. At this time, the damaged quick-change base 2 can be easily removed from the mold body 1. When installing the new quick-change base 2, simply align the frame plate 202 at the top of the support base 201 on the quick-change base 2 with the bottom opening groove 101 of the mold body 1, and operate the coupling component 204 again to push the two fixing blocks 203 to both sides and insert them into the fixing grooves 102 for fixing. This achieves quick fixing of the quick-change base 2 and the mold body 1. The whole process does not require complicated alignment and cumbersome bolt operation, and can ensure the stability of the connection.

[0017] The following is the specific structure of the coupling component 204: The frame plate 202 has through slots 2021 on both sides for the fixing block 203 to pass through. The coupling component 204 includes guide rails 2041 fixed to the front and rear sides of the frame plate 202, and sliders 2042 are slidably connected to the left and right sides of the guide rails 2041. A vertical plate 2043 is fixedly connected between the two sliders 2042. The fixing block 203 is fixed on the opposite surface of the vertical plate 2043 and the through slot 2021. The bottom end of the vertical plate 2043... A bearing housing 2044 is fixedly connected, and a roller bearing 2045 is installed inside the bearing housing 2044. A rotating rod 2046 is embedded in the inner ring of each roller bearing 2045. A screw A2047 is fixedly connected to the end of the rotating rod 2046 opposite to the support base 201. A screw hole 2011 for threaded connection with the screw A2047 is opened on the surface of the support base 201 opposite to the screw A2047. A handle 2048 is fixedly connected to the other end of the rotating rod 2046.

[0018] When disassembling the quick-change base 2, the worker first grasps the handle 2048 fixed to the end of the rotating rod 2046 in the coupling assembly 204 and rotates it in the opposite direction, causing the rotating rod 2046 to rotate within the bearing seat 2044 through the roller bearing 2045 (the rotating rod 2046 drives the inner ring of the roller bearing 2045 to rotate, and its inner ring rotates along its outer ring). This causes the screw A2047 at the other end of the rotating rod 2046 to gradually unscrew from the screw hole 2011 on the support seat 201. As the screw A2047 is unscrewed, the vertical plate 2043 fixedly connected to the bearing seat 2044 will drive the sliders 2042 slidably connected to the guide rails 2041 on both sides to slide towards the middle of the frame plate 202. This causes the fixing block 203 fixed on the vertical plate 2043 to retract from the through groove 2021 into the frame plate 202 and disengage from the fixing groove 102 on the mold body 1. At this point, the quick-change base 2 can be removed from the mold body 1 as a whole. When installing the new quick-change base 2, first align the frame plate 202 at the top of the support base 201 on the quick-change base 2 with the lower opening slot 101 of the mold body 1 (at this time, the fixing block 203 is aligned with the fixing groove 102). Then, hold the handle 2048 and rotate the rotating rod 2046 in the forward direction so that the screw A 2047 is screwed into the screw hole 2011 of the support base 201 (it is necessary to manually push the bearing seat 2044 to make the screw A 2047 contact the screw hole 2011 before rotating). Push the vertical plate 2043 to drive the slider 2042 to slide along the guide rail 2041 to both sides of the frame plate 202, so that the fixing block 203 passes through the through slot 2021 of the frame plate 202 and is inserted into the fixing groove 102 of the mold body 1, thus completing the fixed installation of the quick-change base 2 and the mold body 1. The whole process does not require complicated alignment and tedious bolt operation (only the frame plate 202 and the lower opening slot 101 need to be aligned once).

[0019] The above demonstrates the stability of the connection in several ways: First, the precise fit between the fixing block 203 and the fixing groove 102 ensures that during installation, after the frame plate 202 is inserted into the lower opening groove 101, the fixing block 203 aligns with the fixing groove 102. Subsequently, the fixing block 203 passes through the through groove 2021 and inserts into the fixing groove 102 to form a mechanical locking structure, which effectively limits the relative displacement between the quick-change base 2 and the mold body 1. Second, the threaded connection between the screw A2047 and the screw hole 2011 allows the screw A2047 to be screwed into the screw hole 2011 when the handle 2048 is rotated in the forward direction. The self-locking characteristic of the thread prevents the screw A2047 from loosening on its own, thus firmly supporting the vertical plate 2043 and preventing the fixing block 203 from detaching from the fixing groove 102. Thirdly, the vertical plate 2043 is slidably connected to the guide rail 2041 through the slider 2042. When the slider 2042 slides along the guide rail 2041, it can ensure that the vertical plate 2043 moves in a stable direction, so that the fixing block 203 is always accurately inserted into the fixing groove 102 and will not loosen due to deviation. These structures work together to ensure the stability of the connection between the quick-change base 2 and the mold body 1.

[0020] Furthermore, this utility model designs a detachable connection between the support base 201 and the quick-change base 2. When the support base 201 wears or deforms due to long-term support of the frame plate 202 and bearing the weight of molten steel, or when the frame plate 202 or coupling component 204 at its top malfunctions and needs to be repaired or replaced, it is not necessary to disassemble and replace the entire quick-change base 2. Only the connection structure between the support base 201 and the quick-change base 2 needs to be disassembled separately to repair or replace the damaged support base 201 and its auxiliary parts, which greatly reduces maintenance costs. The specific detachable structure is as follows: a positioning block 4 is fixedly connected to the top of the quick-change base 2, and a positioning groove 2012 for the positioning block 4 to be inserted is opened at the bottom of the support base 201. Mounting plates 5 with through holes 501 are fixedly connected to both sides of the support base 201. A screw B6 that can pass through the through hole 501 is also fixedly connected to the support base 201, and a nut is threaded on the outer side wall of the screw B6. When disassembling the support base 201, the worker first uses tools to loosen and remove the nut on the outer wall of the screw B6, then lifts the support base 201 upwards, removes the mounting plate 5 from the screw B6, and simultaneously separates the positioning groove 2012 at the bottom of the support base 201 from the positioning block 4 at the top of the quick-change base 2, thus releasing the fixed connection between the support base 201 and the quick-change base 2. The support base 201 (including the top frame plate 202 and coupling assembly 204) can then be removed from the quick-change base 2. When installing the support base 201, first... The positioning groove 2012 at the bottom of the support base 201 is aligned with the positioning block 4 at the top of the quick-change base 2 and inserted to complete the initial positioning of the support base 201. At this time, the screw B6 also passes through the through hole 501 on the mounting plates 5 on both sides of the support base 201. Finally, the nut is installed on the outer side wall of the screw B6 and tightened to achieve a stable connection between the support base 201 and the quick-change base 2. The whole process does not require complicated tools, and the cooperation between the positioning block 4 and the positioning groove 2012 can quickly ensure the accurate installation position of the support base 201, greatly improving the efficiency of disassembly and assembly.
