Description

TECHNICAL FIELD

[0001] The utility model relates to mould technical field especially relates to a cage forming die. BACKGROUND

[0002] The origin of cage forming die is closely related to the development of bearing industry. In the early stage, with the improvement of the performance requirements of mechanical equipment on bearings, a tool capable of accurately forming the cage was needed to meet the demand of bearing production. In the early stage of bearing development, the structure and manufacturing process of the cage were relatively simple. For example, the early rolling bearings of railway freight cars used steel plate stamping to form the cage. The forming die at that time was mainly designed for simple stamping process, and the steel plate was processed into a specific shape of cage through the stamping die. With the progress of technology, the requirements for the precision, strength and wear resistance of the bearing cage are continuously improved, which promotes the continuous development and improvement of the cage forming die. Different types of cages, such as die-cast cages, plastic-cast cages, etc., also have their own forming dies to meet the needs of different materials and processes.

[0003] However, for traditional equipment, the traditional cage forming die structure requires a lot of time and effort to adjust the position and fixing method of the die during installation, which not only is inefficient, but also is difficult to ensure the accuracy and stability of the die installation. This leads to displacement or loosening of the die during the forming process, which affects the forming quality of the cage and causes size deviation, irregular shape and other problems, which need to be improved. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at solving the technical problems raised in the background technology.

[0005] This utility model adopts the following technical solution: a retainer forming mold, including an operating table, a fixed frame fixedly installed at the top of the operating table, a hydraulic cylinder fixedly installed at the top of the fixed frame, an upper mold fixedly installed at the output end of the hydraulic cylinder, an injection groove penetrating the surface of the upper mold, a sliding groove opened on the surface of the operating table, a lead screw fitted inside the sliding groove, a gear fixedly installed on the surface of the lead screw, a synchronous belt drivingly connected to the surface of the gear, a handwheel fixedly installed at one end of the lead screw, and a slider threadedly connected to the surface of the lead screw. A fixed plate is fixedly installed at the top of the slider. A groove is formed at the top of the fixed plate, and a cooling fan is fitted inside the groove. An air inlet mesh is fixedly installed on the surface of the fixed plate. A moving groove is formed on the surface of the fixed plate, and a second lead screw is fitted inside the moving groove. A clamping plate is threaded onto the surface of the second lead screw. A second bevel gear is fixedly installed at one end of the second lead screw. A third bevel gear is fitted inside the moving groove. A rotating block is fixedly installed at one end of the second lead screw. A lower mold is placed on the top of the fixed plate and the mating surface of the clamping plate. A heat dissipation groove is formed on the bottom surface of the lower mold.

[0006] Preferably, the heat dissipation groove is wound in a ring shape inside the lower mold, and the bottom end of the heat dissipation groove is in close contact with the air outlet of the cooling fan. The surface of the rotating block is provided with anti-slip textures, which are multiple sets and distributed circumferentially on the surface of the rotating block. Here, the ring-shaped winding inside the lower mold increases the contact area with the air outlet of the cooling fan, making heat dissipation more uniform and efficient, effectively reducing the mold temperature and improving the molding quality.

[0007] Preferably, the number of the lead screw, bevel gear, and clamping plate is four sets, which are circumferentially distributed at the top and inside of the fixed plate. The surfaces of the multiple sets of bevel gears mesh with the surfaces of the bevel gears. Here, the four sets of circumferentially distributed structures can clamp the lower mold from multiple directions, making the lower mold evenly stressed, more firmly fixed, preventing the mold from shifting during the molding process, and ensuring molding accuracy.

[0008] Preferably, the number of gear one, lead screw one, slider, fixed plate, and lower mold are all two sets, symmetrically distributed at the top of the operating table, and the surface of gear one meshes with the surface of the timing belt. Here, the two symmetrically distributed gear one, lead screw one, slider, fixed plate, and lower mold can simultaneously perform the forming operation of two cages, improving production efficiency.

[0009] Preferably, there are two sets of hydraulic cylinders and fixing frames, symmetrically distributed above the operating platform. The output ends of both sets of hydraulic cylinders are connected and fixed to the surface of the upper mold. Multiple sets of air inlets are circumferentially distributed on the side of the fixing plate, and each air inlet is connected through one end of the groove. Here, the two symmetrically distributed sets of hydraulic cylinders and fixing frames provide more stable pressure to the upper mold, ensuring a tight fit between the upper and lower molds and improving molding quality.

[0010] Preferably, the lower mold has a placement groove inside its top end, a top plate is placed inside the placement groove, an operating groove is formed at the bottom end of the placement groove, a movable column is fitted inside the placement groove, a push block is fitted inside the operating groove, a movable rod is fixedly installed at the rear end of the push block, a spring is fitted on the outer surface of the movable rod, and a push handle is fixedly installed at the rear end of the movable rod. Here, the spring provides a restoring force; when the push handle is released, the spring returns the push block and the movable rod to their initial positions, preparing for the next demolding operation.

[0011] Preferably, the number of the moving rods and springs is three sets, arranged in an array at the rear end of the push handle and the push block. One end of each spring is connected and fixed to the surface of the lower mold, and the other end of each spring is connected and fixed to the surface of the push handle. Here, the three sets of arrayed moving rods and springs ensure that the push handle is subjected to uniform force, guaranteeing smooth movement of the push block. At the same time, the spring's restoring action is more stable and reliable, improving the stability and efficiency of the demolding operation.

[0012] Preferably, the number of movable columns is three sets, arranged in an array inside the lower mold and at the bottom of the top plate. The top plate is circular, and the top ends of the movable columns are connected and fixed to the bottom ends of the top plate. The push block is trapezoidal, and the bottom ends of the movable columns are semi-circular, with the bottom ends of the movable columns fitting against the surface of the push block. Here, the three sets of arrayed movable columns can evenly transmit the pushing force of the push block to the top plate, allowing the top plate to rise smoothly and ensuring that the molded retainer can be easily demolded, avoiding product damage.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up an operating table and a fixed frame structure, multiple structures with clamping plates work together during mold installation. This eliminates the need for workers to spend a lot of time and effort adjusting the mold's position and fixing method, effectively improving the equipment's fixing efficiency and ensuring the accuracy and stability of mold installation. It prevents mold displacement or loosening during the molding process, effectively preventing issues such as dimensional deviations and irregular shapes that could affect the forming quality of the retainer. For heat dissipation, multiple cooling fan structures work together to improve the mold's heat dissipation effect during continuous production, preventing any impact on the retainer's forming accuracy and surface quality. Furthermore, it reduces mold wear, increases mold lifespan, and effectively reduces production costs.

[0015] 2. In this utility model, by setting up a placement groove, a top plate, an operating groove, a moving column, a push block, a moving rod, a spring, and a push handle structure, when the equipment is in use, by pushing the push handle, the push block moves in the operating groove, the push block pushes the moving column, and then the top plate rises, pushing the formed retainer out of the placement groove, which facilitates the demolding of the product and effectively improves the rapid demolding effect of the equipment.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1

[0026] Please see Figures 1-5This utility model provides a technical solution: a retainer forming mold, including an operating table 1, a fixed frame 2 fixedly installed on the top of the operating table 1, a hydraulic cylinder 3 fixedly installed on the top of the fixed frame 2, an upper mold 4 fixedly installed on the output end of the hydraulic cylinder 3, an injection groove 5 penetrating the surface of the upper mold 4, a sliding groove 6 opened on the surface of the operating table 1, a lead screw 7 sleeved inside the sliding groove 6, a gear 8 fixedly installed on the surface of the lead screw 7, a synchronous belt 9 drivingly connected to the surface of the gear 8, a handwheel 10 fixedly installed on one end of the lead screw 7, a slider 11 threadedly connected to the surface of the lead screw 7, a fixed plate 12 fixedly installed on the top of the slider 11, and a recessed part opened on the top of the fixed plate 12. A cooling fan 14 is fitted inside the groove 13. An air inlet mesh 15 is fixedly installed on the surface of the fixing plate 12. A movable groove 16 is formed on the surface of the fixing plate 12. A second lead screw 17 is fitted inside the movable groove 16. A clamping plate 18 is threadedly connected to the surface of the second lead screw 17. A second bevel gear 19 is fixedly installed at one end of the second lead screw 17. A third bevel gear 20 is fitted inside the movable groove 16. A rotating block 21 is fixedly installed at one end of the second lead screw 17. A lower mold 22 is placed on the top of the fixing plate 12 and the mating surface of the clamping plate 18. A cooling groove 23 is formed on the bottom surface of the lower mold 22. When using this retainer forming mold, first, the operating table 1 is placed in a suitable working position. Then, the handwheel 10 is turned, which drives the first lead screw 7 to rotate. When the first lead screw 7 rotates, the slider 11 threadedly connected to it moves in the groove 6 on the surface of the operating table 1. The movement of the slider 11 moves the top fixing plate 12 to a suitable position. Next, the lower mold 22 is placed on the top of the fixed plate 12 and the mating surface of the clamping plate 18. The rotating block 21 is rotated, causing the lead screw 17 to rotate. The rotation of the lead screw 17 moves the clamping plate 18, which is threaded to it, thus clamping and fixing the lower mold 22 onto the fixed plate 12. Then, the hydraulic cylinder 3 at the top of the fixed frame 2 is activated. The output end of the hydraulic cylinder 3 pushes the upper mold 4 downwards, causing the upper mold 4 to fit against the lower mold 22. At this time, the material required for molding is injected through the injection groove 5 on the surface of the upper mold 4 to perform the cage molding operation. During the molding process, the cooling fan 14 in the groove 13 at the top of the fixed plate 12 is turned on. Air enters through the air inlet mesh 15 on the surface of the fixed plate 12 and is blown out by the cooling fan 14, dissipating heat from the cooling grooves 23 on the bottom surface of the lower mold 22 to ensure that the mold operates within a suitable temperature range. After the cage molding is completed, the hydraulic cylinder 3 is turned off, causing the upper mold 4 to rise and reset. Then, the clamping plate 18 is released, and the molded cage is removed.

[0027] Please see Figures 1-5The heat dissipation groove 23 is wound in a ring shape inside the lower mold 22. The bottom end of the heat dissipation groove 23 is in close contact with the air outlet of the cooling fan 14. The surface of the rotating block 21 is provided with anti-slip texture. There are multiple sets of anti-slip textures, which are distributed circumferentially on the surface of the rotating block 21. There are four sets of lead screw 17, bevel gear 19 and clamping plate 18, which are distributed circumferentially on the top and inside of the fixed plate 12. The surfaces of multiple sets of bevel gear 19 mesh with the surfaces of bevel gear 20. There are two sets of gear 8, lead screw 7, slider 11, fixed plate 12 and lower mold 22, which are symmetrically distributed on the top of the operating table 1. The surface of gear 8 meshes with the surface of the synchronous belt 9. There are two sets of hydraulic cylinder 3 and fixed frame 2, which are symmetrically distributed above the operating table 1. The output ends of the two sets of hydraulic cylinder 3 are connected and fixed to the surface of the upper mold 4. There are multiple sets of air inlet mesh 15, which are circular on the side of the fixed plate 12. The air inlet mesh 15 is connected to one end of the groove 13. There are three sets of moving rods 29 and springs 30, which are arranged in an array at the rear end of the push handle 31 and the push block 28. One end of the spring 30 is connected and fixed to the surface of the lower mold 22, and the other end of the spring 30 is connected and fixed to the surface of the push handle 31. There are three sets of moving pillars 27, which are arranged in an array inside the lower mold 22 and at the bottom end of the top plate 25. The top plate 25 is circular. The top end of the moving pillar 27 is connected and fixed to the bottom end of the top plate 25. The push block 28 is trapezoidal. The bottom end of the moving pillar 27 is semi-circular. The bottom end of the moving pillar 27 fits against the surface of the push block 28. The top plate 25 is circular, which matches the shape of the cage. The shape design of the push block 28 and the moving pillar 27 makes the contact and pushing between the push block 28 and the moving pillar 27 smoother, and improves the demolding success rate.

[0028] Example 2

[0029] Please see Figures 3-4The lower mold 22 has a placement groove 24 inside its top, and a top plate 25 is placed inside the placement groove 24. An operating groove 26 is provided at the bottom of the placement groove 24, and a movable column 27 is fitted inside the placement groove 24. A push block 28 is fitted inside the operating groove 26. A movable rod 29 is fixedly installed at the rear end of the push block 28, and a spring 30 is fitted on the outer surface of the movable rod 29. A push handle 31 is fixedly installed at the rear end of the movable rod 29. When it is necessary to remove the molded retainer from the lower mold 22, first locate the push handle 31 at the bottom of the lower mold 22. Grasp the push handle 31 and push it forward. The push handle 31 drives the movable rod 29 fixed at its front end to move forward. When the movable rod 29 moves forward, it pushes the push block 28 fitted inside the operating groove 26 forward. As the push block 28 moves forward, it pushes the movable column 27, which is in contact with it, upward. Since the top of the movable column 27 is connected and fixed to the top plate 25 placed in the placement slot 24, the upward movement of the movable column 27 will also drive the top plate 25 upward. The upward movement of the top plate 25 will push the molded retainer placed in the placement slot 24 out of the lower mold 22, thus facilitating the removal of the retainer. After the retainer is removed, the push handle 31 is released. At this time, the spring 30 sleeved on the outer surface of the movable rod 29 will play its role. One end of the spring 30 is connected to the surface of the lower mold 22, and the other end is connected to the surface of the push handle 31. The elastic force of the spring 30 will cause the push handle 31, the movable rod 29, and the push block 28 to move backward and return to the initial position. The movable column 27 will also descend, and the top plate 25 will return to the placement slot 24, preparing for the next molding and demolding operation.

[0030] Working Principle: When using this cage forming mold, first place the operating table 1 in a suitable working position. Then, turn the handwheel 10, which drives the lead screw 7 to rotate. When the lead screw 7 rotates, the slider 11, which is threaded to it, moves within the groove 6 on the surface of the operating table 1. The movement of the slider 11 moves the top fixing plate 12 to a suitable position. Next, place the lower mold 22 on the top of the fixing plate 12 and the mating surface of the clamping plate 18. Rotate the rotating block 21, which drives the lead screw 17 to rotate. The rotation of the lead screw 17 moves the clamping plate 18, which is threaded to it, thereby clamping and fixing the lower mold 22 onto the fixing plate 12. Afterward, activate the hydraulic cylinder 3 at the top of the fixing frame 2. The output end of the hydraulic cylinder 3 pushes the upper mold 4 downward, causing the upper mold 4 to fit against the lower mold 22. At this time, the material required for molding is injected through the injection groove 5 on the surface of the upper mold 4 to perform the cage forming operation. During the molding process, the cooling fan 14 in the groove 13 at the top of the fixed plate 12 is turned on. Air enters through the air inlet mesh 15 on the surface of the fixed plate 12 and is blown out by the cooling fan 14 to dissipate heat from the cooling grooves 23 on the bottom surface of the lower mold 22, ensuring that the mold operates within a suitable temperature range. After the retainer is molded, the hydraulic cylinder 3 is turned off, causing the upper mold 4 to rise and reset. Then, the clamping plate 18 is released, and the molded retainer is removed. When it is necessary to remove the molded retainer from the lower mold 22, first locate the push handle 31 at the bottom of the lower mold 22. Hold the push handle 31 and push it forward. The push handle 31 drives the moving rod 29 fixed at its front end to move forward. When the moving rod 29 moves forward, it pushes the push block 28, which is fitted in the operating groove 26, to move forward. During the forward movement of the push block 28, it pushes the moving column 27 that is in contact with it to move upward. Since the top of the moving column 27 is connected and fixed to the top plate 25 placed in the placement groove 24, the upward movement of the moving column 27 will also drive the top plate 25 to move upward. Moving the top plate 25 upward will push the molded retainer placed in the placement slot 24 out of the lower mold 22, making it easier to remove the retainer. After the retainer is removed, the push handle 31 is released. At this time, the spring 30 sleeved on the outer surface of the moving rod 29 will play its role. One end of the spring 30 is connected to the surface of the lower mold 22, and the other end is connected to the surface of the push handle 31. The elastic force of the spring 30 will cause the push handle 31, the moving rod 29 and the push block 28 to move backward and return to the initial position. The moving column 27 also descends accordingly, and the top plate 25 returns to the placement slot 24, preparing for the next molding and demolding operation.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
