Description

Technical Field

[0001] This utility model relates to the field of aluminum ingot casting technology, specifically to a quick mold changing mechanism for aluminum ingot casting molds. Background Technology

[0002] In the field of aluminum ingot casting, the specifications and shape of aluminum ingots need to be flexibly adjusted according to the needs of downstream applications (such as aerospace, automobile manufacturing, building materials, etc.). Different specifications of aluminum ingots require matching casting molds with corresponding cavity sizes and number of cavities. At the same time, under the long-term high temperature and high pressure working environment, aluminum ingot casting molds are prone to wear, deformation, and aluminum adhesion on the cavity surface. If they continue to be used, it will lead to a decrease in the forming accuracy of aluminum ingots, an increase in surface quality defects, and even safety hazards such as mold cracking. Therefore, the molds must be inspected, maintained or replaced regularly. In addition, aluminum ingot casting production lines often need to switch to the production of aluminum ingots of different alloy grades. The casting process parameters of different alloys have different requirements for the material, coating and structure of the molds, and it is also necessary to replace them with suitable molds to ensure casting quality.

[0003] In the aluminum ingot casting process, traditional mold changing methods make it difficult to quickly and accurately position the mold. In the past, there was a lack of effective positioning methods, making it difficult to ensure that the mold can be accurately positioned in the middle of the top of the machine tool. This resulted in the mold being unable to accurately receive the molten aluminum during aluminum ingot casting, which affected the quality of the cast aluminum ingot and made it difficult to meet the standards.

[0018] Please see Figure 1-5 This utility model provides a technical solution for a quick mold changing mechanism for aluminum ingot casting molds: Example 1: A quick mold changing mechanism for an aluminum ingot casting mold, comprising a machine tool 1 and a mold 4, wherein the machine tool 1 is provided with a positioning mechanism 2 and a fixing mechanism 3; The positioning mechanism 2 includes a motor 21 fixedly connected to the inner bottom wall of the machine tool 1. The output end of the motor 21 is fixedly connected to a rotating shaft 22 via a coupling. A rhombus-shaped block 23 is fixedly connected to the top of the rotating shaft 22. Two hinge rods 24 are hinged to the bottom of the rhombus-shaped block 23. A movable plate 25 is hinged to the end of each hinge rod 24 away from the rhombus-shaped block 23. Several sliding blocks 251 are fixedly connected to the top of each movable plate 25. Several sliding grooves 252 are formed on the top of the machine tool 1. The sliding blocks 251 are slidably connected to the inner walls of the several sliding grooves 252. A connecting sleeve 253 is fixedly connected to the top of each sliding block 251. Each connecting sleeve 253 is slidably connected to the top of the machine tool 1. Piston blocks 254 are slidably connected to the inner walls of each connecting sleeve 253. Piston rods 255 are fixedly connected to each piston block 254. The ends of the piston rods 255 away from the piston blocks 254 slidably extend to the outside of the connecting sleeves 253. Positioning frames 256 are fixedly connected to the ends of the piston rods 255 away from the piston blocks 254. Positioning pulleys 257 are rotatably connected to the inner walls of each positioning frame 256. The positioning pulleys 257 contact the left and right sides of the mold 4 respectively. Springs 258 are wound around the outer walls of each piston rod 255. One end of spring 258 is fixedly connected to the inner wall of connecting sleeve 253, and the other end of spring 258 is fixedly connected to piston block 254. Several connecting sleeves 253 are connected with air guide hoses 26. Two fixed rods 27 are fixedly connected to the top of machine tool 1, and electronic air valves 28 are fixedly connected to each of the two fixed rods 27. The ends of several air guide hoses 26 away from connecting sleeves 253 are respectively connected to the two electronic air valves 28. When positioning mold 4, motor 21 can drive shaft 22 and rhombus block 23 to rotate, causing two hinge rods 24 on rhombus block 23 to drive two moving plates 25 to move closer to each other synchronously. The sliding block 251 and the multiple sliding grooves 252 cooperate with each other, so that the two moving plates 25 can only slide left and right on the inner top wall of the machine tool 1. When the two moving plates 25 are close to each other, the electronic air valve 28 can be opened, and the connecting sleeve 253 is connected to the outside air through the air guide hose 26. After the multiple positioning pulleys 257 contact the left and right sides of the mold 4, the multiple piston rods 255 slide away from each other on the connecting sleeve 253, so that the spring 258 is stretched. Since the size and shape of different molds 4 are different, the stretching degree of the multiple springs 258 is different. After adjusting according to the shape of the mold 4, the electronic air valve 28 is closed.

[0019] Example 2: Based on Example 1, the fixing mechanism 3 includes two extension arms 31 fixedly connected to the inner wall of the machine tool 1. The inner walls of the two extension arms 31 are rotatably connected to several pulleys 32. The mold 4 is placed on the top of the pulleys 32. The front side of the machine tool 1 is threadedly connected to a screw handle 34. The rear end of the screw handle 34 is rotatably connected to a push plate 35. The push plate 35 is slidably connected to the inner wall of the machine tool 1 and contacts the front side of the machine tool 1. The top of the machine tool 1 is fixedly connected to a baffle 33. The rear side of the mold 4 contacts the front side of the baffle 33. While positioning the mold 4, the screw handle 34 can be rotated to move the push plate 35 backward on the inner wall of the machine tool 1, which, together with the baffle 33, abuts against the rear side of the mold 4 to fix the mold 4.

[0020] In practical use, the quick mold changing mechanism of the aluminum ingot casting mold of this utility model is equipped with a positioning mechanism 2 and multiple positioning pulleys 257 to quickly position the mold 4, so that the mold 4 is positioned in the middle of the top of the machine tool 1. This ensures that the mold 4 can accurately receive the aluminum liquid during the aluminum ingot casting process, and ensures that the quality of the cast aluminum ingot meets the standards. At the same time, it also provides a good foundation for the subsequent fixing mechanism 3 to fix the mold 4, making the whole mold changing process more efficient and accurate. By setting a fixing mechanism 3 to fix the mold 4, the displacement of the mold 4 due to the impact of molten aluminum or mechanical vibration during the aluminum ingot casting process is effectively prevented, thus ensuring the stability and continuity of the casting process.
