DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, a large diameter bearing copper sleeve casting mold includes a first outer mold 1, a second outer mold 6 and an inner mold 3, wherein the first outer mold 1 and the second outer mold 6 are both arranged in a semi-arc structure, and the first outer mold 1 and the second outer mold 6 are both movably installed in a slide groove 9 at the top of a base 10, and the slide groove 9 is used for the first inner mold 1 and the second outer mold 6 to slide;

[0022] The top of the base 10 is located in the slide groove 9 and a positioning plate 16 is fixedly installed. The diameter of the positioning plate 16 is consistent with the inner diameter of the inner mold 3. The inner mold 3 is sleeved on the outer side of the positioning plate 16. A casting groove 5 is provided between the inner mold 3 and the first outer mold 1 and the second outer mold 6. A cooling water tank 4 is provided inside the inner mold 3.

[0023] A threaded hole 2 is provided at the top of the inner mold 3, and the threaded hole 2 is provided at two locations. The two threaded holes 2 are used for the bottom end of the rotating rod 20 to be installed and inserted. The bottom end of the rotating rod 20 is provided with threads adapted to the threaded holes 2. The top end of the rotating rod 20 is rotatably connected to the bottom end of the second piston push rod 13; the top end of the second piston push rod 13 passes through the top cover 12 and is fixedly connected to the output end of the second electric cylinder 11. The second electric cylinder 11 is provided at two locations and is fixedly installed on the top of the top cover 12;

[0024] The top cover 12 is arranged directly above the base 10, and a support 14 is arranged between the top cover 12 and the base 10, and the support 14 is arranged at four places; a water outlet 15 is opened at the center of the positioning plate 16, and a drainage cavity 17 is arranged on one side of the base 10, and a floor drain can be installed on the bottom surface near the base 10 to facilitate the water discharged from the drainage cavity 17 to flow away from the floor drain, and the interior of the drainage cavity 17 is connected with the interior of the water outlet 15, and the water outlet 15 can be blocked with a plug;

[0025] The sides of the first outer mold 1 and the second outer mold 6 that are away from each other are fixedly connected to one end of the first piston push rod 7, and the other end of the first piston push rod 7 is fixedly connected to the output end of the first electric cylinder 8; both ends of the first outer mold 1 are provided with plug blocks 18, and the plug blocks 18 are adapted to the slots 19, and the slots 19 are opened at both ends of the second outer mold 6, and the diameter of the circular chamber formed by the first inner mold 1 and the second inner mold 6 is larger than the diameter of the inner mold 3.

[0026] It should be noted that the utility model is a large-diameter bearing copper sleeve casting mold. When the copper sleeve needs to be cast, firstly, the two first electric cylinders 8 are started by an external power supply. The first electric cylinder 8 drives the first piston push rod 7 to push the first outer mold 1 and the second outer mold 6, so that the first outer mold 1 and the second outer mold 6 are close to each other until the plug 18 is inserted into the slot 19 to form a circular chamber. Then the inner mold 3 is sleeved on the outer side of the positioning plate 16, so that an annular chamber is formed between the inner mold 3 and the first outer mold 1 and the second outer mold 6, that is, the casting trough 5. The basic model of the copper sleeve is formed by injecting molten copper into the casting trough 5. After the casting is completed, cooling water can be injected into the cooling water tank 4 in the inner mold 3. Before injecting the cooling water, the water outlet 15 needs to be blocked with a plug. Accelerate the cooling and solidification of the copper sleeve. After the copper sleeve solidifies, use some longer rods to pull out the plug of the water outlet 15. Because the cooling water is at a high temperature at this time, you cannot directly reach out and pull it out. Let the cooling water flow away from the water outlet 15 and be discharged from the base 10 from the drainage cavity 17. Then start the second electric cylinder 11 through the power supply. The second electric cylinder 11 drives the second piston push rod 13 and the rotating rod 20 to descend, and insert the rotating rod 20 into the threaded hole 2 at the top of the inner mold 3, and rotate and tighten it. Then, the second piston push rod 13 is driven to rise by the start of the second electric cylinder 11, and then the inner mold 3 is driven to rise to realize the demolding of the inner mold 3. Finally, by starting the first electric cylinder 8, the first piston push rod 7 is driven to move away from each other so that the first outer mold 1 and the second outer mold 6 are separated, and the copper sleeve is obtained.

[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
