Description

Technical Field

[0001] The present application relates to the technical field of casting molds, and in particular to a casting mold for producing a bearing hub. Background Art

[0002] The main function of the bearing hub is to bear weight and provide precise guidance for the rotation of the wheel hub. It bears both axial load and radial load. It is a very important component. The bearing hub is composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of the bearings are all carried out on the automobile production line.

[0003] During the production process of the bearing hub, a casting mold is usually required to perform pressure casting on the bearing hub to ensure the quality of the bearing hub production. For example, the Chinese patent with publication number CN210160358U in the relevant technology proposes a casting mold for a bearing ring for high-speed rail, which can unload the material used for the mold into a ring-shaped inclined groove to form a bearing, and the second half mold ring and the second half mold column are contacted with the second half groove, and the first half groove is contacted with the first half mold column and the first half membrane ring, so that the mold shaping advantage is achieved through extrusion.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the casting mold of this design does not have the advantage of fast demolding, resulting in the bearing hub being unable to be quickly removed from the casting mold after production is completed. The staff is required to use tools to open the casting mold first. This method is not only time-consuming and labor-intensive, but also increases the labor intensity of the staff. Moreover, it is impossible to quickly cast the next bearing hub, which prolongs the production time of the bearing hub, is inconvenient to use, and reduces the use efficiency and effect of the casting mold. Utility Model Content

[0005] In order to solve the problem that the casting mold does not have the advantage of fast demolding, resulting in the bearing hub cannot be quickly removed from the casting mold after production is completed, the staff needs to use tools to open the casting mold first. This method is not only time-consuming and labor-intensive, but also increases the labor intensity of the staff, and it is impossible to quickly cast the next bearing hub. The present application provides a casting mold for bearing hub production.

[0006] The present application provides a casting mold for producing a bearing hub using the following technical solution:

[0007] A casting mold for producing a bearing hub comprises a supporting base, an upper casting mold, a lower casting mold and a die pressing mechanism, wherein the top of the supporting base is movably connected to the lower casting mold, and the upper casting mold is located directly above the lower casting mold;

[0008] The die pressing mechanism includes a connecting shaft movably connected to a supporting base, a manual turning handle is fixedly connected to the bottom end of the connecting shaft, a power bevel gear is fixedly connected to the outer side of the connecting shaft, two transmission bevel gears are meshed on the outer side of the power bevel gear, a movable shaft is fixedly connected to the inner sides of the two transmission bevel gears, the outer sides of the two movable shafts are fixedly connected to the first bevel gear, the outer sides of the two first bevel gears are meshed with the second bevel gear, the inner sides of the two second bevel gears are fixedly connected to threaded rods, the outer sides of the two threaded rods are threadedly connected to threaded blocks, the outer sides of the two threaded blocks are fixedly connected to limiting blocks, a movable push plate is fixedly connected between the opposite sides of the two limiting blocks, the bottom of the movable push plate is movably connected to the upper casting mold, and the left and right sides of the top of the supporting base are fixedly connected to a driving box.

[0009] By adopting the above technical scheme, the material for making the bearing hub can be stored through the lower casting mold, and the technician only needs to turn the manual turning handle, and the connection shaft and the power bevel gear can be driven to rotate through the rotation of external force, and through the meshing relationship between the two transmission bevel gears and the power bevel gear and the two first bevel gears and the two second bevel gears, when the power bevel gear rotates, the two transmission bevel gears, the two movable shafts, the two first bevel gears, the two second bevel gears and the two threaded rods can be rotated respectively, and through the threaded relationship between the two threaded rods and the two threaded blocks, when the two threaded rods rotate, the two threaded blocks, the two limiting blocks, the movable push plate and the upper casting mold can be driven downward in turn, so that the material inside the lower casting mold can be die-cast by moving the upper casting mold downward to cooperate with the lower casting mold, and the staff does not need to use tools to die-cast the upper casting mold and the lower casting mold, which can reduce the labor intensity of the staff.

[0010] Similarly, rotating the manual handle in the opposite direction can sequentially drive the two threaded blocks, two limit blocks, the movable push plate and the upper casting mold to move upward, so that the upper casting mold can be quickly separated from the lower casting mold, so that the bearing hub material cast on the inner side of the lower casting mold can be taken out, which can ensure the speed of bearing hub processing and discharge, and does not require staff to manually open the upper casting mold, which can save mold opening time and thus increase the speed of bearing hub processing.

[0011] Optionally, lower mold blocks are fixedly connected to the left and right sides of the lower casting mold, and the number of the lower mold blocks is four. The inner sides of the four lower mold blocks are threaded with movable screws, and the bottom ends of the movable screws pass through the lower mold blocks and the support base in sequence and extend to the inner side of the support base.

[0012] By adopting the above technical solution, the lower casting mold can be stably connected to the supporting base through four lower mold blocks and four movable screws, thereby avoiding the lower casting mold from shifting during use, ensuring the use effect of the lower casting mold, and at the same time, the lower casting mold can be disassembled from the top of the supporting base to facilitate regular disassembly, replacement or maintenance of the lower casting mold, thereby increasing the service life of the lower casting mold.

[0013] Optionally, upper mold blocks are fixedly connected to the left and right sides of the upper casting mold, and the number of the upper mold blocks is four. The inner sides of the four upper mold blocks are threaded with connecting screws, and the top ends of the connecting screws sequentially penetrate the upper mold block and the movable push plate and extend to the inner side of the movable push plate.

[0014] By adopting the above technical scheme, the upper casting mold can be stably connected to the movable push plate through four upper mold blocks and four connecting screws, thereby preventing the upper casting mold from falling off during use, so as to ensure the use effect of the upper casting mold. At the same time, the upper casting mold can be disassembled from above the movable push plate to facilitate regular disassembly, replacement or maintenance of the upper casting mold, thereby increasing the service life of the upper casting mold.

[0015] Optionally, an upper mold positioning block is fixedly connected to the top of the upper casting mold, a first positioning square groove is opened at the bottom of the movable push plate, the upper mold positioning block is located on the inner side of the first positioning square groove, the length of the upper mold positioning block is equal to the length of the first positioning square groove, and the width of the upper mold positioning block is equal to the width of the first positioning square groove.

[0016] By adopting the above technical solution, the upper casting mold can be installed and positioned through the upper mold positioning block and the first positioning square groove. When the upper casting mold is installed, the staff can immediately position the upper casting mold on the movable push plate, which can save a lot of staff time for measuring and aligning the upper casting mold. At the same time, simple limiting can be performed when installing the upper casting mold to avoid the upper casting mold from shaking left and right during the installation process, which can improve the installation time of the upper casting mold.

[0017] Optionally, a lower mold positioning block is fixedly connected to the bottom of the lower casting mold, a second positioning square groove is opened on the top of the support base, the lower mold positioning block is located on the inner side of the second positioning square groove, the length of the lower mold positioning block is equal to the length of the second positioning square groove, and the width of the lower mold positioning block is equal to the width of the second positioning square groove.

[0018] By adopting the above technical solution, the lower casting mold can be installed and positioned through the lower mold positioning block and the second positioning square groove. When the lower casting mold is installed, the staff can immediately position the lower casting mold on the supporting base, which can save a lot of staff time for measuring and aligning the lower casting mold. At the same time, simple limiting can be performed when the lower casting mold is installed to avoid the lower casting mold from shaking left and right during the installation process, which can improve the installation time of the lower casting mold.

[0019] Optionally, the outer sides of the two threaded rods are fixedly connected with first bearings, the number of the first bearings is four, the two first bearings on the left side are fixedly connected to the left drive box, and the two first bearings on the right side are fixedly connected to the right drive box, and the top end of the threaded rod passes through the second bevel gear, the support base, the drive box, the first bearing and the threaded block in sequence and extends to the inner side of the first bearing.

[0020] By adopting the above technical solution, the two threaded rods are rotated by the external force of the two second bevel gears, so the four first bearings can support the two threaded rods, the two first bearings on the left side can support the left threaded rod, and the two first bearings on the right side can support the right threaded rod. At the same time, the four first bearings can ensure the rotation stability of the two threaded rods, and can avoid the phenomenon of the two threaded rods shaking left and right during rotation.

[0021] Optionally, the outer sides of the two movable shafts are fixedly connected with second bearings, and the two second bearings are fixedly connected to the support base. The end of the movable shaft away from the transmission bevel gear sequentially passes through the transmission bevel gear, the first bevel gear and the second bearing and extends to the inner side of the second bearing.

[0022] By adopting the above technical solution, the movable shaft needs to support the rotation of the transmission bevel gear and the first bevel gear at the same time. Therefore, the two movable shafts can be supported and limited by the two second bearings, which can avoid the two movable shafts being limited due to the balance of external forces during rotation. Therefore, the two second bearings can improve the rotation stability of the two movable shafts, and can ensure that the two movable shafts respectively drive the two transmission bevel gears and the two first bevel gears to support the rotation.

[0023] Optionally, a third bearing is fixedly connected to the outer side of the connecting shaft, and the third bearing is fixedly connected to the support base. The top end of the connecting shaft sequentially passes through the support base, the power bevel gear and the third bearing and extends to the inner side of the third bearing.

[0024] By adopting the above technical solution, during the rotation of the connecting shaft, the manual turning of the manual handle to drive the connecting shaft and the power bevel gear to support the rotation is not smooth. Therefore, by setting a third bearing, the manual turning handle can be used to drive the connecting shaft to rotate, thereby ensuring the stability of the rotation of the connecting shaft, and at the same time, the top of the connecting shaft can be supported and limited. The third bearing consists of four parts: a small circle, a large circle, a ball and a ball distribution frame. The function of the small circle is to cooperate with the connecting shaft and rotate with the connecting shaft, and the function of the large circle is to cooperate with the support base to play a supporting role.

[0025] Optionally, T-shaped sliders are fixedly connected to the left and right sides of the movable push plate, and T-shaped long grooves are opened on the opposite sides of the two drive boxes. The number of T-shaped sliders and T-shaped long grooves is four, and the four T-shaped sliders are respectively slidably connected to the four T-shaped long grooves, and the two drive boxes are movably connected to the movable push plate.

[0026] By adopting the above technical solution, the stability of the movable push plate moving up and down can be ensured by setting four T-shaped sliders and four T-shaped long grooves. The left and right sides of the movable push plate are supported only by two limiting blocks, which will make the balance force of the movable push plate moving up and down insufficient, and further make the movable push plate move up and down unsmoothly. Therefore, the four T-shaped sliders and four T-shaped long grooves can not only limit the movement of the movable push plate, but also ensure the stability of the movable push plate moving up and down.

[0027] Optionally, a limiting long hole is opened on the opposite side of the two drive boxes, the two limiting blocks are slidably connected to the two limiting long holes respectively, the width of the limiting block is equal to the width of the limiting long hole, and the inner sides of the two threaded blocks are respectively provided with threaded holes that are compatible with the outer threads of the two threaded rods.

[0028] By adopting the above technical solution, the two threaded blocks can be limited by two limiting blocks and two limiting long holes. Because the two threaded rods drive the two threaded blocks to move, a limiting mechanism must be set, otherwise the two threaded rods will drive the two threaded blocks to rotate and move up and down when rotating, thereby failing to drive the movable push plate and the upper casting mold to move up and down. Because the two limiting blocks and two limiting long holes can support the movable push plate while limiting the circular rotation of the two threaded blocks.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. Pour the bearing hub material to be cast into the inner side of the lower casting mold. By turning the manual handle, the connecting shaft and the power bevel gear can be driven to rotate in turn, which will in turn drive the two transmission bevel gears, the two movable shafts and the two first bevel gears to rotate, and then respectively drive the two second bevel gears and the two threaded rods to rotate, which will in turn drive the two threaded blocks, the two limit blocks, the movable push plate and the upper casting mold to move downward. In the process of the upper casting mold moving downward, the lower casting mold can be used to cooperate with the lower casting mold to cast the bearing hub material inside the lower casting mold, and the lower casting mold can be tightly fitted with the upper casting mold. There is no need for staff to press the upper casting mold and the lower casting mold, which can ensure the casting effect of the bearing hub material.

[0031] 2. When it is necessary to discharge and demold the bearing hub material die-cast on the inner side of the lower casting mold, according to the above principle, the manual handle is rotated in the opposite direction, and the movable push plate and the upper casting mold can be driven to move upward in sequence through the connection and cooperation between the connecting shaft, the power bevel gear, the two transmission bevel gears, the two movable shafts, the two first bevel gears, the two second bevel gears, the two threaded rods, the two threaded blocks and the two limit blocks. During the upward movement of the upper casting mold, it will be separated from the lower casting mold, so that the bearing hub material cast on the inner side of the lower casting mold can be taken out, which can ensure the speed of bearing hub processing and discharging, and the staff does not need to manually open the upper casting mold, thereby achieving the purpose of rapid demolding of the casting mold. After the bearing hub is produced, it can be quickly taken out from the casting mold, and the staff does not need to use tools to open the casting mold.

[0032] 3. The lower casting mold can be stably connected to the support base through four lower mold blocks and four movable screws, and the upper casting mold can be stably connected to the movable push plate through four upper mold blocks and four connecting screws, so as to avoid the upper casting mold and the lower casting mold from shifting during use. At the same time, the upper casting mold and the lower casting mold can be disassembled to facilitate regular disassembly, replacement or maintenance of the upper casting mold and the lower casting mold, thereby ensuring the service life and use effect of the upper casting mold and the lower casting mold.

[0053] The implementation principle of a casting mold for manufacturing a bearing hub in the embodiment of the present application is as follows:

[0054] The bearing hub material to be cast is poured into the inner side of the lower casting mold 14. The connecting shaft 2 and the power bevel gear 4 can be driven to rotate in sequence by rotating the manual turning handle 3. Because the two transmission bevel gears 5 are meshed with the power bevel gear 4, the two transmission bevel gears 5, the two movable shafts 6 and the two first bevel gears 7 are driven to rotate in sequence during the rotation of the power bevel gear 4. Because the two first bevel gears 7 are respectively meshed with the two second bevel gears 8, the two second bevel gears 8 and the two threaded rods 9 are driven to rotate in sequence during the rotation of the two first bevel gears 7. The rods 9 are respectively threadedly connected with the two threaded blocks 10, so during the rotation of the two threaded rods 9, the two threaded blocks 10, the two limiting blocks 11, the movable push plate 12 and the upper casting mold 13 will be driven to move downward in sequence. During the downward movement of the upper casting mold 13, the lower casting mold 14 can be used to cast the bearing hub material inside the lower casting mold 14, and the lower casting mold 14 can be closely fitted with the upper casting mold 13, so that the staff does not need to perform compression molding on the upper casting mold 13 and the lower casting mold 14, which can ensure the casting effect of the bearing hub material.

[0055] When it is necessary to discharge and demould the bearing hub material die-cast inside the lower casting mold 14, according to the above principle, the manual handle 3 is rotated in the opposite direction, and the movable push plate 12 and the upper casting mold 13 can be driven to move upward in sequence through the connection and cooperation between the connecting shaft 2, the power bevel gear 4, the two transmission bevel gears 5, the two movable shafts 6, the two first bevel gears 7, the two second bevel gears 8, the two threaded rods 9, the two threaded blocks 10 and the two limiting blocks 11. During the upward movement of the upper casting mold 13, it will be separated from the lower casting mold 14, so that the bearing hub material cast inside the lower casting mold 14 can be taken out, which can ensure the speed of bearing hub processing and discharging, and the staff does not need to manually open the upper casting mold 13;

[0056] The lower casting mold 14 can be stably connected to the support base 1 through four lower mold blocks 16 and four movable screws 17 to prevent the lower casting mold 14 from being offset during use. At the same time, the lower casting mold 14 can be disassembled from the upper side of the support base 1 to facilitate regular disassembly, replacement or maintenance of the lower casting mold 14, thereby ensuring the use effect of the lower casting mold 14.

[0057] The upper casting mold 13 can be stably connected to the movable push plate 12 through four upper mold blocks 18 and four connecting screws 19 to prevent the upper casting mold 13 from falling off during use. At the same time, the upper casting mold 13 can be disassembled from above the movable push plate 12 to facilitate regular disassembly, replacement or maintenance of the upper casting mold 13, thereby ensuring the use effect of the upper casting mold 13.

[0058] Compared with the prior art, the overall structure is simple and easy to use, and the purpose of rapid demolding of the casting mold is achieved.
