Description

Technical Field

[0001] This utility model belongs to the field of casting cooling technology, specifically a cooling device for bearing casting that is easy to disassemble and assemble. Background Technology

[0002] Bearings are supporting components of mechanical transmission shafts, used to guide the rotation of the shaft or realize linear motion. They are an important guarantee for the performance, function and efficiency of the host machine. Bearing casting is a process in which liquid metal is poured into a mold and allowed to cool naturally or be placed on a cooling device to solidify and form a bearing blank of the required shape. In the existing bearing casting, the cooling device is fixed on one side of the lower mold. When casting bearings of different specifications, it is difficult to change the mold cavity shape according to casting needs because the mold cavity shape of the lower mold is fixed. Installing a cooling device on each lower mold can easily increase the processing cost. Therefore, it is necessary to improve it. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a cooling device for bearing casting that is easy to disassemble and assemble. It solves the problem that the existing cooling devices for bearing casting are fixed on one side of the lower mold. When casting bearings of different specifications, the mold cavity shape of the lower mold is fixed and it is difficult to change it at will according to the casting needs. Installing a cooling device on each lower mold can easily increase the processing cost.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for bearing casting that is easy to disassemble and assemble, comprising a mounting base, a lower mold slidably connected to the top of the mounting base, an upper mold provided on the top of the mounting base, the upper mold closely covering the top of the lower mold, positioning blocks fixedly installed at the four corners of the bottom of the upper mold, positioning grooves provided at the four corners of the top of the lower mold, the positioning grooves corresponding to the positions of the positioning blocks, placement grooves provided on both sides of the top of the mounting base, holding plates fixedly connected to both sides of the lower mold, the holding plates corresponding to the positions of the placement grooves, two supporting side plates symmetrically fixedly installed at the bottom of the mounting base, a pouring gate fixedly installed on the top of the upper mold, two snap-fit ​​strips symmetrically fixedly installed on both sides of the upper mold, two connecting plates symmetrically fixedly installed on both sides of the mounting base, plate buckles rotatably connected to the top of the connecting plates via pins, and snap fasteners rotatably connected to the middle positions of both sides of the plate buckles via pins, the tops of the snap fasteners corresponding to the snap-fit ​​strips.

[0005] As a further embodiment of this utility model: a water tank is fixedly installed on one side of the mounting base, a water outlet is provided at the bottom of the water tank, a water pump is fixedly installed at the bottom of the water tank, the input end of the water pump is connected to the water outlet through a conduit, and a cooling pipe is fixedly connected to the output end of the water pump.

[0006] As a further embodiment of this utility model: the bottom of the mounting base is provided with a rectangular groove, the cooling pipes are arranged in a spiral shape in the rectangular groove, and the cooling pipes are in contact with the bottom of the lower mold.

[0007] As a further embodiment of this utility model: a support plate is fixedly installed inside the rectangular groove, and a fixing strip is fixedly installed on the top of the support plate, and the fixing strip is engaged with the cooling pipe.

[0008] As a further embodiment of this utility model: an isolation plate is fixedly installed inside the water tank, the top of the isolation plate is provided with a water inlet, and several cooling plates are fixedly installed on one side of the isolation plate on the inner wall of the water tank.

[0009] As a further embodiment of this utility model: one end of the cooling pipe passes through the bottom of the water tank and winds around several cooling plates in an S-shaped path, and the other end of the cooling pipe inside the water tank is connected to the water inlet.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This easy-to-assemble and disassemble cooling device for bearing casting uses snap-fit ​​strips and buckles to place the upper and lower molds on top of the mounting base. After the positioning block at the bottom of the upper mold and the positioning groove on the lower mold are aligned, the holding plate and the placement groove are aligned. At this time, the snap-fit ​​strip is located above the buckle. Rotating the buckle causes the buckle to rise and rest on the top of the snap-fit ​​strip. Then, pressing the buckle down causes the buckle to snap into the snap-fit ​​strip, thus completing the fixing of the upper and lower molds by the mounting base. This facilitates the assembly, connection, and disassembly of the mounting base, upper mold, and lower mold.

[0012] 2. This easily disassembled cooling device for bearing casting, by means of a water pump and cooling pipes, draws coolant from the water tank through the outlet when cooling the lower mold. The coolant flows through the cooling pipes at the top of the lower mold and absorbs heat at the bottom of the lower mold, causing the liquid metal inside the lower mold to gradually cool and solidify. Finally, the coolant in the cooling pipes enters the water tank through the inlet and is cooled by several cooling plates, allowing the cooled coolant to be re-injected into the water tank for recycling.

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a cooling device for bearing casting that is easy to disassemble and assemble, including a mounting base 1, a lower mold 4 slidably connected to the top of the mounting base 1, an upper mold 2 provided on the top of the mounting base 1, and the upper mold 2 closely covering the top of the lower mold 4. Positioning blocks 16 are fixedly installed at the four corners of the bottom of the upper mold 2, and positioning grooves 17 are provided at the four corners of the top of the lower mold 4, and the positions of the positioning grooves 17 and the positioning blocks 16 correspond to each other. By providing positioning grooves 17 and positioning blocks 16, the positioning grooves 17 of the lower mold 4 are engaged with the positioning blocks 16 of the upper mold 2, so that the upper mold 2 and the lower mold 4 will not shift when they are in contact.

[0019] The mounting base 1 has placement slots 19 on both sides of the top. The lower mold 4 has holding plates 18 fixedly connected to both sides, and the holding plates 18 correspond to the positions of the placement slots 19. The mounting base 1 has two supporting side plates 14 fixedly installed symmetrically at the bottom. The upper mold 2 has a pouring port 15 fixedly installed at the top. By providing supporting side plates 14, the mounting base 1 is kept away from the placement surface, increasing the air circulation space at the bottom of the device and avoiding heat dissipation obstruction due to being close to the ground.

[0020] Two snap-fit ​​strips 20 are symmetrically fixedly installed on both sides of the upper mold 2, and two connecting plates 21 are symmetrically fixedly installed on both sides of the mounting base 1. The top of the connecting plate 21 is rotatably connected to the plate buckle 22 by a pin, and the middle position of both sides of the plate buckle 22 is rotatably connected to the snap-fit ​​strip 20 by a pin. The top of the snap-fit ​​strip 23 corresponds to the snap-fit ​​strip 20. With the snap-fit ​​strip 23, when the upper mold 2 and the lower mold 4 are placed on the mounting base 1, the plate buckle 22 is rotated to make the snap-fit ​​strip 23 rise until the snap-fit ​​strip 20 overlaps with the snap-fit ​​strip 20. The plate buckle 22 is pressed to make the snap-fit ​​strip 23 fasten tightly in the snap-fit ​​strip 20, thereby fixing the upper mold 2 and the lower mold 4 on the mounting base 1.

[0021] A water tank 3 is fixedly installed on one side of the mounting base 1. The bottom of the water tank 3 is provided with a water outlet 6. A water pump 5 is fixedly installed at the bottom of the water tank 3. The input end of the water pump 5 is connected to the water outlet 6 through a conduit. The output end of the water pump 5 is fixedly connected to a cooling pipe 8. With the water pump 5 installed, the water pump 5 draws the coolant from the water tank 3 into the cooling pipe 8. The coolant flows along the bottom of the lower mold 4 through the S-shaped cooling pipe 8, absorbing the heat emitted by the lower mold 4 and cooling the liquid metal in the lower mold 4. Then, it is transported back to the water tank 3 through the cooling pipe 8, thereby realizing the circulation of the coolant in the cooling pipe 8.

[0022] The bottom of the mounting base 1 is provided with a rectangular groove 13, in which the cooling pipes 8 are arranged in a spiral shape and are in contact with the bottom of the lower mold 4. A support plate 9 is fixedly installed inside the rectangular groove 13, and a fixing strip 10 is fixedly installed on the top of the support plate 9. The fixing strip 10 is engaged with the cooling pipes 8. By providing the fixing strip 10, the cooling pipes 8 are arranged in a spiral shape on the fixing strip 10, so that the arrangement of the cooling pipes 8 will not be easily changed, thus improving the stability of heat dissipation.

[0023] An isolation plate 12 is fixedly installed inside the water tank 3. The top of the isolation plate 12 is provided with a water inlet 7. Several cooling plates 11 are fixedly installed on one side of the isolation plate 12 on the inner wall of the water tank 3. By providing the isolation plate 12, the isolation plate 12 isolates the cooling plates 11 from the coolant, preventing the cooling plates 11 from directly contacting the coolant and causing the coolant to condense ice crystals on the surface of the cooling plates 11, which would affect the use of the coolant.

[0024] One end of the cooling pipe 8 passes through the bottom of the water tank 3 and winds around several cooling plates 11 in an S-shape. The other end of the cooling pipe 8 inside the water tank 3 is connected to the water inlet 7. With the cooling plates 11, the refrigerant in the cooling pipe 8 flows through multiple cooling plates 11 to cool down the high-temperature refrigerant in the cooling pipe 8 that has absorbed a lot of heat, so that the refrigerant can be circulated and reused, thereby improving the utilization rate of the refrigerant.

[0025] The working principle of this utility model is as follows:

[0026] Place the holding plate 18 into the corresponding slot 19, put the lower mold 4 into the top of the mounting base 1, and then fit the upper mold 2 and the lower mold 4 together through the positioning block 16 and the positioning slot 17, so that the upper mold 2 and the lower mold 4 are tightly attached together. At this time, the snap-fit ​​strip 20 is located directly above the snap-fit ​​strip 23. Rotate the plate buckle 22 so that the snap-fit ​​strip 20 contacts the snap-fit ​​strip 23, and then snap off the plate buckle 22 to fix the upper mold 2 and the lower mold 4 on the mounting base 1, thereby completing the installation of the cooling device. Pour the liquid metal into the upper mold 2 and the lower mold 4 through the pouring port 15, and start... The pump 5 draws coolant from the water tank 3 into the cooling pipe 8, allowing the coolant to flow through the bottom of the lower mold 4. The cooling pipe 8 then cools the lower mold 4. Subsequently, the cooling pipe 8 passes through the water tank 3 and wraps around the surface of the cooling plate 11 in an S-shape inside the water tank 3, further cooling the coolant in the cooling pipe 8. Finally, the cooled coolant inside the cooling pipe 8 flows back into the water tank 3 through the inlet 7, improving the utilization rate of the coolant and thus realizing the cooling cycle of the device. This accelerates the cooling and forming of the liquid metal in the mold and improves the efficiency of bearing casting.
