Description

Technical Field

[0001] The present invention relates to the field of manufacturing a steering gear bracket, and particularly to an optimized structure of a bracket and a mold lifting device therefor. Background Art

[0002] The steering gear bracket is an important component in an automotive steering system, which mainly functions to support and fix the steering gear. Currently, the structure of the steering gear bracket applied to light trucks is relatively heavy (as shown in Figure 8 ), resulting in not only a large consumption of raw materials but also a high transportation cost during the casting and installation processes. Moreover, the existing bracket is provided with a partition structure inside, which makes it impossible to directly complete the operation of placing the lower sand core in one go during mold lifting, resulting in a rather cumbersome operation process.

[0003] Furthermore, during mold lifting of the existing steering gear bracket, workers pick up the brackets one by one, and then use tools to remove the sand cores inside the brackets. After the sand cores are removed, the brackets are transferred to a designated location. This operation mode leads to a too large workload for individual workers and affects the efficiency of placing the lower sand core due to the proficiency of individual operations. Therefore, the present solution proposes an optimized structure of a bracket and a mold lifting device therefor. Summary of the Invention

[0004] An optimized structure of a bracket and a mold lifting device therefor proposed by the present invention solve the problems of the large weight and troublesome mold lifting of the existing steering gear bracket.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] An optimized structure of a bracket includes a connecting plate, an upper assembly angle plate fixedly connected to one end of the connecting plate, and a lower assembly angle plate fixedly connected to the other end of the connecting plate. Arc-shaped grooves are formed on the opposite sides of the upper assembly angle plate and the lower assembly angle plate. The bottom portions on both sides of the connecting plate are arc structures, and bosses are fixed on both the lower assembly angle plate and the upper assembly angle plate.

[0007] A mold lifting device for an optimized structure of a bracket includes:

[0008] An installation assembly, which includes a bottom plate, a support column rotatably connected to the top of the bottom plate, an installation column fixed to the top of the support column, and an installation disk fixed to the top of the installation column. A plurality of placement grooves are formed on the top surface of the installation disk, and a feeding position, a mold lifting position, and a discharging position are arranged outside the installation disk;

[0009] The blank holding mechanism is arranged in the placing groove and is used to optimize the structure of holding the bracket. The blank holding mechanism includes a fixed frame rotatably connected in the placing groove and a moving block installed on the outer periphery of the mounting post through an elastic member. A stop block is provided on one side of the fixed frame away from the axis of the mounting disc. One side of the moving block is hinged with a movable connecting rod, and the other end of the movable connecting rod is hinged with the bottom surface of the fixed frame;

[0010] The linkage mechanism is installed on the bottom surface of the fixed frame and is used to drive the stop block to rotate when the fixed frame rotates;

[0011] The receiving plate is arranged on one side of the bottom plate and is located at the blanking position. A driving assembly for driving the moving block to move downward is installed on the bottom surface of the receiving plate;

[0012] Through the above technical solutions, not only can the weight of the bracket be effectively reduced, but also the adaptability of the bracket when connected to other components is higher. At the same time, the setting of the mold lifting device also greatly reduces the difficulty of mold lifting and improves the production efficiency.

[0013] As a further improvement of the above solution, a motor is installed on the bottom surface of the bottom plate. A driving gear is sleeved on the output shaft of the motor. The bottom of the support column extends below the bottom plate and is fixed with a driven gear meshing with the driving gear.

[0014] As a further improvement of the above solution, the bottom plate is of a conical structure. A scraping plate abutted against the top surface of the bottom plate is fixed on the outer periphery of the support column.

[0015] As a further improvement of the above solution, a limiting ring coaxially arranged with the bottom plate is fixed on the outer periphery of the bottom plate, and a notch is formed on the limiting ring directly below the mold lifting position.

[0016] As a further improvement of the above solution, a mounting groove for mounting the moving block is formed on the side surface of the mounting post. A through hole is formed on the bottom surface of the mounting groove. The moving block is slidably connected in the mounting groove.

[0017] As a further improvement of the above solution, the elastic member includes a movable column fixed on the bottom surface of the moving block and a spring sleeved on the outer periphery of the movable column. The bottom of the movable column penetrates through the through hole and extends below the mounting post. A fixed column is fixed on one side of the bottom of the movable column. The top of the spring is fixedly connected to the bottom of the moving block, and the bottom of the spring is fixedly connected to the bottom surface of the mounting groove.

[0018] As a further improvement of the above solution, the driving assembly includes a telescopic member installed on the bottom surface of the receiving plate and a pressing block fixed on the output end of the telescopic member. The pressing block cooperates with the fixed column and is used to press down the fixed column located at the blanking position during the elongation of the telescopic member.

[0019] As a further improvement of the above solution, a transmission shaft is rotatably connected to the bottom surface of the fixed frame, the stopper is fixed to the outer periphery of the transmission shaft, and transmission gears are fixed to both ends of the transmission shaft.

[0020] As a further improvement of the above solution, there are two sets of linkage components, which are respectively installed on both sides of the bottom surface of the fixed frame. The linkage component includes a transmission rack arranged on the bottom surface of the fixed frame, a limit sleeve movably sleeved on the outer periphery of the transmission rack, and a fixed connecting rod hinged to one end of the transmission rack close to the mounting column. The transmission rack meshes with the transmission gear, the limit sleeve is fixedly connected to the bottom surface of the fixed frame, and the other end of the fixed connecting rod is hinged to the outer periphery of the mounting column.

[0021] As a further improvement of the above solution, guide plates are fixed to both long sides of the fixed frame. The top surfaces of the two guide plates are both right triangle structures, and the inclined surfaces face the inner side of the fixed frame.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. Optimize the original steering gear bracket. Not only arc grooves are opened on the upper angle plate and the lower angle plate for assembly to achieve the purpose of weight reduction, but also the partition plate inside the original bracket is removed. Therefore, when removing the mold, no lower sand core is required, and only the bracket shell needs to be knocked to make the sand core fall off. Moreover, the side of the connecting plate is set as a connecting mechanism with a sloped arc, so that it can be more conveniently connected to other components during installation.

[0024] 2. Through the setting of the mold removal device, during mold removal, it can be directly placed in the placement groove, and then when it rotates to the blanking position with the installation disk, the operator knocks on the outside of the bracket, so that the sand core inside the bracket directly falls off. Then when it rotates to the blanking position again, the driving component operates, driving the moving block to descend, so that the fixed frame with the bracket on it flips downward. During the downward flipping process of the fixed frame, the stopper is also driven by the linkage mechanism to flip outward, so that the bracket on the fixed frame can automatically slide onto the receiving plate, achieving the purpose of automatic blanking. The whole process greatly reduces the operation difficulty and improves the work efficiency.

[0025] 3. Through the setting of the limit ring and the scraper, the sand core falling on the top of the bottom plate can be automatically discharged from the notch on the limit ring while the support column rotates, thereby achieving the purpose of facilitating the cleaning of the sand core.

[0036] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be combined arbitrarily to form new embodiments

[0037] Embodiment 1:

[0038] Please refer to Figure 1 - Figure 7 A mold lifting device with an optimized structure of a bracket in this embodiment includes:

[0039] Installation assembly, which includes a bottom plate 1, a support column 2 rotatably connected to the top of the bottom plate 1, a mounting column 3 fixed to the top of the support column 2, and a mounting plate 5 fixed to the top of the mounting column 3. A plurality of placement grooves 6 are provided on the top surface of the mounting plate 5. A motor is installed on the bottom surface of the bottom plate 1. A driving gear is sleeved on the output shaft of the motor. The bottom of the support column 2 extends below the bottom plate 1 and is fixed with a driven gear meshing with the driving gear. A loading position, a mold stripping position, and a discharging position are provided outside the mounting plate 5. When stripping the mold, the device to be stripped is placed in the placement groove 6. Then, driven by the motor, the mounting plate 5 rotates accordingly. After each rotation of the placement groove 6 to a working station, the motor stops rotating for a period of time and then resumes operation, so that the bracket to be stripped can be loaded at the loading position, the core can be detached at the mold stripping position, and finally the discharging can be completed at the discharging position. The whole process is fast and simple, which helps to improve the efficiency.

[0040] A material supporting mechanism, which is arranged in the placement groove 6 and is used for supporting and optimizing the structure of the bracket. The material supporting mechanism includes a fixed frame 8 rotatably connected in the placement groove 6 and a moving block 19 installed on the outer periphery of the mounting column 3 through an elastic member. One side of the moving block 19 is hinged with a movable connecting rod 18, and the other end of the movable connecting rod 18 is hinged with the bottom surface of the fixed frame 8. An installation groove 22 for installing the moving block 19 is provided on the side surface of the mounting column 3. A through hole is provided on the bottom surface of the installation groove 22. The moving block 19 is slidably connected in the installation groove 22. The elastic member includes a movable column 20 fixed to the bottom surface of the moving block 19 and a spring sleeved on the outer periphery of the movable column 20. The bottom of the movable column 20 penetrates through the through hole and extends below the mounting column 3. And a fixed column 21 is fixed to one side of the bottom of the movable column 20. The top of the spring is fixedly connected to the bottom of the moving block 19, and the bottom of the spring is fixedly connected to the bottom surface of the installation groove 22. During the mold stripping process, the bracket is placed on the top of the fixed frame 8 in the installation groove 22 located at the placement position. Then, after the mounting plate rotates, the bracket will rotate to the mold stripping position and stop. At this time, the worker knocks on the bracket shell, so that the core inside the bracket falls off. Then, the bracket follows the placement groove 6 to rotate to the discharging position and waits for discharging.

[0041] The material receiving plate 4 is arranged on one side of the bottom plate 1 and is located at the blanking position. A driving component for driving the moving block 19 to move downward is installed on the bottom surface of the material receiving plate 4. The driving component includes a telescopic member 16 installed on the bottom surface of the material receiving plate 4 and a pressing block fixed to the output end of the telescopic member 16. The pressing block cooperates with the fixed column 21 and is used to press down the fixed column 21 located at the blanking position during the elongation of the telescopic member 16. After the placement groove 6 rotates to the blanking position, the mounting disk 5 temporarily stops rotating. Then, the telescopic member 16 in the driving component elongates, driving the pressing block to descend. After the pressing block descends and contacts the fixed column 21, it will press down the fixed column 21, driving the movable column 20 and the moving block 19 to move downward synchronously. The spring is compressed accordingly. As the moving block 19 moves downward, the end of the fixed frame 8 away from the axis of the mounting disk 5 will rotate downward, causing the bracket placed on the top of the fixed frame 8 to gradually slide off its top onto the material receiving plate 4, thus completing the automatic blanking process. Then the telescopic member 16 contracts again, and the moving block 19 will move upward under the action of the spring, and the movable column 20 also moves upward synchronously with the moving block 19 until the moving block 19 returns to its original position and the fixed frame 8 also returns to the inside of the placement groove 6. Then, the mounting disk 5 rotates again driven by the motor.

[0042] Guide plates 7 are fixed to both long sides of the fixed frame. The top surfaces of the two guide plates 7 are both right triangle structures, and the inclined surfaces face the inside of the fixed frame. The setting of the guide plates can limit and guide the position of the bracket placed on the top surface of the fixed frame, preventing it from colliding or rubbing against the inner wall of the placement groove 6.

[0043] Embodiment 2:

[0044] Combined with Figure 1 - Figure 5, on the basis of Embodiment 1, the further improvement in this embodiment is as follows: A stop block 9 is provided on one side of the fixed frame 8 away from the axis of the mounting disc 5. A linkage assembly for driving the stop block 9 to rotate when the fixed frame 8 rotates is installed on the bottom surface of the fixed frame 8. A transmission shaft 13 is rotatably connected to the bottom surface of the fixed frame 8. The stop block 9 is fixed to the outer periphery of the transmission shaft 13. Transmission gears 14 are fixed to both ends of the transmission shaft 13. The linkage assembly includes two groups and is respectively installed on both sides of the bottom surface of the fixed frame 8. The linkage assembly includes a transmission rack 12 provided on the bottom surface of the fixed frame 8, a limit sleeve 15 movably sleeved on the outer periphery of the transmission rack 12, and a fixed connecting rod 17 hinged to one end of the transmission rack 12 close to the mounting column 3. The transmission rack 12 meshes with the transmission gear 14. The limit sleeve 15 is fixedly connected to the bottom surface of the fixed frame 8. The other end of the fixed connecting rod 17 is hinged to the outer periphery of the mounting column 3. The setting of the stop block 9 can prevent the bracket placed on the fixed frame 8 from falling from the opening of the placement groove 6 under the action of centripetal force during the rotation of the mounting disc 5. When the fixed frame 8 is turned downward, the transmission rack 12 will also rotate synchronously with it. Since the height of the connection point between the fixed connecting rod 17 and the mounting column 3 remains unchanged, the transmission rack 12 will be driven to move away from the axis of the mounting disc 5 during the downward rotation of the fixed frame 8, thereby driving the transmission gear 14 to rotate forward, and the transmission shaft 13 will also rotate forward accordingly, driving the stop block 9 to flip outward until it is parallel to the length direction of the fixed frame 8, so that the stop block 9 will not hinder the sliding of the bracket on the fixed frame 8. On the contrary, when the fixed frame 8 is turned upward again, it can drive the transmission rack 12 to move toward the axis of the mounting disc 5, so that the stop block 9 can be flipped back again during the upward rotation of the fixed frame 8.

[0045] Embodiment 3:

[0046] Combined with Figure 1 , on the basis of Embodiments 1 and 2, the further improvement in this embodiment is as follows: The bottom plate 1 is of a conical structure. A scraping plate 10 abutted against the top surface of the bottom plate 1 is fixed to the outer periphery of the support column 2. A limit ring 11 coaxially arranged with it is fixed to the outer periphery of the bottom plate 1, and a notch located directly below the mold removal position is opened on the limit ring 11. When the support column 2 rotates, it will drive the scraping plate 10 to rotate synchronously with it. Since the bottom plate 1 is of a conical structure, the top surface of the bottom plate 1 slopes downward from the central position to the outside. After the scraping plate 10 rotates, it can scrape up the core sand on the top of the bottom plate 1 and finally discharge it from the notch on the limit ring 11, so as to achieve the purpose of conveniently cleaning the core sand on the bottom plate 1.

[0047] Embodiment 4:

[0048] Combined with Figure 6 - Figure 8, on the basis of Embodiment 1, Embodiment 2 and Embodiment 3, the further improvement of this embodiment lies in that: the optimized structure of the bracket includes a connecting plate 101, an upper assembly angle plate 102 fixedly connected to one end of the connecting plate 101, and a lower assembly angle plate 103 fixedly connected to the other end of the connecting plate 101. Arc grooves are provided on the opposite sides of the upper assembly angle plate 102 and the lower assembly angle plate 103. The bottoms of both sides of the connecting plate 101 are arc structures. Bosses 104 are fixed on both the lower assembly angle plate 103 and the upper assembly angle plate 102. By providing arc grooves on the upper assembly angle plate 102 and the lower assembly angle plate 103, the weight of the entire bracket can be greatly reduced. Moreover, compared with the existing bracket, the partition plate inside the connecting plate 101 is removed, so that when knocking on the connecting plate 101 during the lower sand core process, the sand core inside can directly fall off. In addition, the slope arc 105 of the arc structure provided on the side of the connecting plate 101 makes the connecting plate 101 have higher adaptability when connecting with other components.

[0049] The above-mentioned implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
