[0002] With the rapid development of industrial manufacturing, steel ingot production, as a key link in basic industries, plays a vital role in the manufacture of various high-strength components. In the steel ingot production process, die casting technology, with its advantages of fast forming speed, high precision, and high production efficiency, has become one of the mainstream processes in steel ingot manufacturing. The die casting process injects molten metal into a mold under high pressure, enabling the rapid generation of workpieces with complex shapes and precise dimensions, making it widely used in large-scale production and demanding manufacturing fields.

[0003] Traditional die-casting equipment for steel ingots often uses a fixed mold design. After the workpiece is formed, the demolding process usually requires manual labor or additional equipment assistance. Due to the simple structure and cumbersome operation of the demolding process, it often leads to workpiece damage, low efficiency, and difficulty in demolding. Some molds lack ejection functions, which can cause workpieces to get stuck, thereby increasing the difficulty of the production process and the burden of manual operation, and reducing production efficiency. To address these issues, a detachable die-casting component for steel ingot die-casting is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a detachable die-casting component for die-casting steel ingots, aiming to improve the problem of inconvenient demolding in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A detachable die-casting assembly for die-casting steel ingots includes a lower mold and an upper mold. The lower mold has a base plate at its bottom and a cavity inside.

Detailed Implementation

[0034] 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.

[0035] Reference Figures 1-4 This utility model provides an embodiment of a detachable die-casting assembly for die-casting steel ingots, comprising a lower mold 2 and an upper mold 12. The lower mold 2 has a base plate 1 at its bottom and an internal cavity. A fixing block 3 is disposed in the lower cavity of the lower mold 2. A rotating shaft 4 is rotatably connected between the fixing blocks 3. A rotating plate 5 is rotatably connected to the side wall of the rotating shaft 4. A pressure plate 11 is fixedly connected to the outer side of the rotating plate 5. A sliding groove 6 is disposed inside the rotating plate 5. A lifting mechanism is disposed in the upper cavity of the lower mold 2, and a connecting mechanism is disposed in the lower cavity of the lower mold 2. The upper mold 12 is located at the top of the lower mold 2, and an injection tube 13 is disposed in its internal groove. The lower mold 2 is used to add die-casting raw materials; the lifting mechanism slides inside the lower mold 2 and is used to eject the formed workpiece from the upper cavity of the lower mold 2. The lifting mechanism includes a slide rod 8, which is slidably connected inside the lower mold 2. The lifting mechanism also includes a top plate 7, which is slidably connected inside the upper cavity of the lower mold 2. The slide rod 8 is fixedly connected to the lower surface of the top plate 7; the connecting mechanism is used to connect the lifting mechanism to the rotating plate 5. The connecting mechanism includes a connecting shaft 10, which is slidably connected inside the slide groove 6. The connecting mechanism also includes a fixing frame 9, which is fixedly connected between the slide rods 8. The connecting shaft 10 is fixedly connected inside the fixing frame 9.

[0036] After the raw material is formed, the pressure plate 11 located on one side of the mold is pressed, causing the rotating plate 5 to deflect around the rotating shaft 4. When the rotating plate 5 deflects, the sliding groove 6 inside it begins to move accordingly. The sliding groove 6 provides a movement trajectory for the connecting shaft 10, ensuring that the connecting shaft 10 can slide inside the sliding groove 6. As the rotating plate 5 deflects, the sliding groove 6 gradually moves upward, and the connecting shaft 10 also slides under the guidance of the sliding groove 6. When the connecting shaft 10 begins to slide upward, the fixed frame 9 drives the sliding rod 8 to move upward in the bottom cavity of the lower mold 2, lifting the top plate 7. As the top plate 7 moves upward, the workpiece will gradually detach from the upper cavity of the lower mold 2. Through the above steps, the formed workpiece is finally lifted out of the mold by the top plate 7, achieving a convenient demolding effect.

[0037] Reference Figure 1 , Figure 2 and Figure 5The fixing mechanism is located on both sides of the bottom of the upper mold 12 and is used to lock the lower mold 2 to the upper mold 12. The fixing mechanism includes a fixing frame 14 and a positioning frame 21. The fixing frame 14 is fixedly connected to both sides of the bottom of the upper mold 12, and the positioning frame 21 is fixedly connected to both sides of the side wall of the lower mold 2. The fixing mechanism also includes a screw 15, which is threaded into the interior of the upper mold 12. The screw 15 passes through the upper mold 12 and is rotatably connected to a movable frame 16 at its bottom. A fixing column 17 is fixedly connected inside the fixing frame 14. A sliding plate 18 is slidably connected to the side wall of the fixing column 17. A connecting plate 19 is rotatably connected between the movable frame 16 and the sliding plate 18. A positioning rod 20 is fixedly connected to the side wall of the sliding plate 18. The side wall of the positioning rod 20 is slidably connected inside the fixing frame 14 and inside the positioning frame 21. A base plate 1 is fixedly connected to the bottom of the lower mold 2, and a reinforcing plate is provided at the connection between the base plate 1 and the lower mold 2.

[0038] When assembling the upper and lower molds, the upper mold 12 is first placed on top of the lower mold 2, and the extended part at the bottom of the upper mold 12 is aligned with the groove on the upper edge of the lower mold 2. After the molds are aligned, the screw 15 is turned. The thread of the screw 15 interacts with the thread inside the upper mold 12, thereby pushing the moving frame 16 downward. As the screw 15 rotates, the moving frame 16 gradually presses down. When the moving frame 16 moves downward, one end of the connecting plate 19 begins to rotate inside the moving frame 16, while the other end rotates inside the slide plate 18 and pushes it to slide along the fixed column 17, gradually pushing the positioning rod 20 outward. When the slide plate 18 pushes the positioning rod 20 to the corresponding position of the positioning frame 21, the front end of the positioning rod 20 is inserted into the positioning frame 21, ensuring a firm connection between the upper mold 12 and the lower mold 2, and ensuring that the mold will not loosen or shift during the die casting process.

[0039] Working principle: When using this equipment, first place the upper mold 12 on top of the lower mold 2 to connect the two. Then, push the moving frame 16 downward by twisting the screw 15. When the moving frame 16 moves downward, it will push the slide plate 18 outward through the connecting plate 19. At this time, one side of the connecting plate 19 will rotate inside the moving frame 16, and the other side will rotate inside the slide plate 18. As the connecting plate 19 deflects, the slide plate 18 will slide on the fixed column 17 and push the positioning rod 20 outward to insert it into the positioning frame 21, thereby completing the connection between the lower mold 2 and the upper mold 12. Then, inject the raw material into the lower mold 2 through the injection tube 13.

[0040] After the raw material is formed, the screw 15 is rotated in the opposite direction to remove the positioning rod 20 from the inside of the positioning frame 21, thereby releasing the lock between the lower mold 2 and the upper mold 12. The upper mold 12 is then removed from the top of the lower mold 2. At this time, the rotating plate 5 is deflected on the rotating shaft 4 by pressing the pressure plate 11. When the rotating plate 5 deflects, the connecting shaft 10 slides inside the sliding groove 6 under the guidance of the sliding groove 6 and gradually moves upward. The top plate 7 is lifted upward by the sliding rod 8, thereby lifting the formed workpiece upward, achieving the effect of easy demolding.

[0041] 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.
