Description

Technical Field

[0001] This utility model belongs to the field of aluminum alloy casting technology, and in particular relates to a loading and unloading mechanism for aluminum alloy wheel hub casting. Background Technology

[0002] Currently, most wheel hubs are made of aluminum alloy, which is manufactured using three methods: gravity casting, forging, and low-pressure precision casting. Gravity casting uses gravity to pour molten aluminum alloy into a mold, and after forming, it is finished by lathe processing and polishing. Due to its simple manufacturing process, the absence of precision casting technology, low cost, and high production efficiency, it is adopted by most manufacturers.

[0003] In the aluminum alloy wheel casting process, the aluminum material needs to be heated, and then the liquid aluminum is poured into the mold to solidify and form a shape. However, in the current production process, the injection of molten aluminum into the mold is generally done manually. The extremely high temperature of the liquid aluminum can easily cause burns to workers, which is very unsafe. After the wheel is cast, it needs to be demolded and transferred. During the demolding and transfer process, the upper mold cannot work, which reduces work efficiency. Utility Model Content

[0020] 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.

[0021] Please see Figure 1-5 As shown, this utility model is a loading and unloading mechanism for aluminum alloy wheel hub casting, including a base plate 1. A motor 2 is fixedly connected to the bottom surface of the base plate 1, and a mounting plate 8 is fixedly connected to the top surface of the base plate 1. A processing table 3 is fixedly connected to the output end of the motor 2. A mounting hole 301 is opened inside the processing table 3. A support plate 4 is fixedly connected inside the mounting hole 301. A fixing plate 401 is fixedly connected to the top of the support plate 4. A side mold 5 is slidably connected to the top surface of the fixing plate 401. An electric push rod 501 is fixedly connected to one side of the side mold 5. The end of the electric push rod 501 away from the side mold 5 is fixedly connected to the inner wall of the mounting hole 301. A bottom mold 6 is fixedly connected to the top surface of the fixing plate 401. A hydraulic rod 801 is fixedly connected to the bottom surface of the mounting plate 8. The hydraulic rod 801 outputs... The upper mold 7 is fixedly connected to the outlet end, and the top of the upper mold 7 is fixedly connected to the injection pipe 701. The electric push rod 501 can drive the side mold 5 to move towards the bottom mold 6. When the two sets of side molds 5 come into contact, the electric push rod 501 is stopped and the hydraulic rod 801 is started. The hydraulic rod 801 drives the upper mold 7 to move downward until the upper mold 7 comes into contact with the side mold 5. Then, the molten metal is injected into the mold through the injection pipe 701. After casting is completed, the motor 2 is started. The motor 2 can drive the processing table 3 to rotate. The processing table 3 is equipped with three sets of side molds 5 and bottom molds 6. The rotation of the processing table 3 drives the processed side molds 5 and bottom molds 6 inside it to move, so that the side molds 5 and bottom molds corresponding to the upper mold 7 are always in a state of waiting to be processed, thereby improving the processing efficiency of the device.

[0022] The lifting mechanism includes an electric push rod 402, a movable plate 403, and a movable column 404. The electric push rod 402 is fixedly connected to the bottom surface of the mounting hole 301, and the movable plate 403 is fixedly connected to the top surface of the electric push rod 402. The movable column 404 is fixedly connected to the top surface of the movable plate 403. The movable column 404 passes through the fixed plate 401 and its top surface is flush with the top surface of the fixed plate 401. The movable column 404 is initially flush with the top surface of the fixed plate 401, which does not affect the casting effect. After casting is completed, the electric push rod 402 can drive the movable plate 403 to move up and down, which in turn drives the movable column 404 to move up and down, so that the cast wheel hub is pushed out of the mounting hole 301 for easy subsequent movement.

[0023] The feeding mechanism includes a raw material box 9, a feed inlet 901, a heating furnace 10, a storage box 11, a valve 1101, a valve 2 1102, and a liquid injection tank 1103. The raw material box 9 is fixedly connected to the top surface of the mounting plate 8, and the feed inlet 901 is fixedly connected to the top surface of the raw material box 9. The heating furnace 10 is installed inside the raw material box 9, and the valve 1 1101 is fixedly connected to the bottom of the heating furnace 10. The storage box 11 is fixedly connected to the bottom surface of the raw material box 9, and the interior of the storage box 11 is connected to the valve 1 1101. The valve 2 1102 is fixedly connected to one side of the storage box 11, and the liquid injection tank 1103 is fixedly connected to the end of the valve 2 1102 away from the storage box 11. A liquid injection pipe 7 is slidably connected inside the mounting plate 8. 01, and the injection pipe 701 is located inside the injection tank 1103. The heating furnace 10 can heat and melt the aluminum material fed from the feed port 901. After the aluminum material is melted, it enters the storage tank 11 through valve one 1101 for temporary storage. When casting the wheel hub, the upper mold 7 moves down, causing the injection pipe 701 to slide inside the mounting plate 8 until the upper mold 7 contacts the side mold 5 and stops moving. At this time, the upper end of the injection pipe 701 is flush with the bottom surface of the injection tank 1103. The valve two 1102 is opened, allowing the aluminum liquid inside the storage tank 11 to enter the injection tank 1103 and flow into the upper mold 7, side mold 5 and bottom mold 6 through the injection pipe 701, thereby completing the casting. This reduces manual feeding operations and avoids the occurrence of high temperature burn accidents.

[0024] Working principle: In operation, aluminum is first fed into the heating furnace 10 through the feed inlet 901. After the aluminum is completely melted, valve 1101 is opened to allow the molten aluminum to enter the storage tank 11. Then, electric push rod 501 is activated to move the side mold 5 towards the bottom mold 6. When the two sets of side molds 5 come into contact, electric push rod 501 is stopped, and hydraulic rod 801 is activated. Hydraulic rod 801 moves the upper mold 7 downward until the upper mold 7 comes into contact with the side molds 5. Then, valve 1102 is opened to allow the molten aluminum inside the storage tank 11 to flow freely. The liquid enters the injection tank 1103 and flows into the upper mold 7, side mold 5 and bottom mold 6 through the injection pipe 701. After casting is completed, the electric push rod 402 is started to move the movable plate 403, which in turn moves the movable column 404 upward, so that the cast wheel hub is pushed out of the mounting hole 301 for easy subsequent handling. Then the motor 2 is started, and the motor 2 drives the moving processing table 3 to rotate, so that the cast wheel hub is removed. At the same time, the side mold 5 and bottom mold 6 to be processed are moved to the bottom of the upper mold 7 for easy casting.

[0025] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
