[0018] The present invention will be further described below with reference to the embodiments.

[0019] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0020] Please see Figures 1-4 This utility model provides a molding device for small automotive bracket parts, including a base plate 1, a molding seat 2 fixedly connected to the top of the base plate 1, a plurality of clamping components rotatably connected to the inner side of the molding seat 2, and a lower mold 10 for manufacturing small automotive bracket parts clamping between the plurality of clamping components. A spur gear ring 8 is rotatably connected to the outer side of the molding seat 2, and the spur gear ring 8 engages at a right angle with one end of the clamping components. The clamping components include an inner threaded sleeve 3 rotatably connected to the inner side of the molding seat 2, a lead screw 4 threadedly connected to the inner side of the inner threaded sleeve 3, and a clamping plate 5 rotatably connected to the end of the lead screw 4 near the lower mold 10. The bottom of the clamping plate 5 is slidably connected to the top of the base plate 1. The clamping plate 5 is fixedly connected to a ball bearing 6 at the end away from the corresponding lead screw 4. The outer side of the lower mold 10 is provided with a groove adapted to the ball bearing 6. The inner thread sleeve 3 is fixedly connected to a driven crown gear 7 on the side away from the lower mold 10. The driven crown gear 7 meshes with the spur gear 8 at a right angle. The side of the forming seat 2 is rotatably connected to a driving crown gear 9, which meshes with the spur gear 8 at a right angle. The outer side of the forming seat 2 is fixedly connected to a motor, the output end of which is fixedly connected to the driving crown gear 9. The center of the base plate 1 is fixedly connected to a second cylinder 17, and the top of the cylinder is fixedly connected to a support plate 18. The bottom end of the lower mold 10 is provided with a groove adapted to the support plate 18, and the support plate 18 is located at the top of the groove.

[0021] Place the appropriate lower mold 10 inside the forming base 2, and insert the support plate 18 into the inner side of the slide groove at the bottom of the lower mold 10. Start the motor and drive the crown gear 9 to drive the spur gear ring 8 to rotate. The spur gear ring 8 rotates by meshing with the driven crown gear 7, causing the inner thread sleeve 3 to rotate. When the inner thread sleeve 3 rotates, the screw 4 moves axially under the action of the inner thread of the inner thread sleeve 3, pushing the clamping plate 5 to move inward, so that the cladding ball 6 is embedded in the cladding groove of the lower mold 10, clamping and fixing the lower mold 10.

[0022] The device cleverly utilizes the meshing transmission relationship between the driving crown gear 9 and the spur gear ring 8 to drive all driven crown gears 7 to rotate synchronously. This not only ensures the uniformity and stability of power transmission, but also, through the threaded transmission between the inner thread sleeve 3 and the lead screw 4, drives the lead screw 4 to make precise axial displacement. This drives the connected clamping plate 5 to move synchronously, thereby achieving stable clamping of lower molds 10 of different sizes. This design allows the device to flexibly adapt to lower molds 10 of various sizes, greatly improving its versatility and adaptability. The device also utilizes the cooperation between the ball bearing 6 and the outer groove of the lower mold 10 to limit the lower mold 10 in the vertical direction. This not only effectively prevents the lower mold 10 from shifting due to vibration or other external forces during the molding process, but also ensures that the lower mold 10 will not move during demolding. As a result, this device demonstrates excellent performance and wide applicability in the molding and processing of small automotive bracket parts.

[0023] Please see Figures 1-4 A fixed frame 11 is fixedly connected to the top of the base plate 1. A cylinder 12 is fixedly connected to the top of the fixed frame 11. A mounting frame 13 is fixedly connected to the bottom of the cylinder 12. An upper mold 14 is slidably connected to the mounting frame 13. The upper mold 14 includes a connecting block 15 fixedly connected to the top. A threaded rod 16 is threadedly connected to the inner side of the mounting frame 13. The other end of the threaded rod 16 passes through the inner side of the connecting block 15. There are three clamping components, which are distributed in a ring on the inner side of the forming seat 2.

[0024] Insert the connecting block 15 above the upper mold 14 into the mounting bracket 13 from the bottom. Rotate the threaded rod 16 to make it enter the connecting block 15 and fix the upper mold 14. Place the blank into the lower mold 10. Start the first cylinder 12 to push the mounting bracket 13 downward, which in turn moves the upper mold 14 downward and into the lower mold 10, squeezing the blank inside until it forms a support part. After forming, the first cylinder 12 retracts, which moves the upper mold 14 upward and returns it to its initial position. Start the second cylinder 17 to push the support plate 18 upward. The top of the support plate 18 pushes the bottom of the support part and pushes it out of the lower mold 10. At the same time, the retaining ball 6 fixes the lower mold 10 to prevent it from shifting, thus completing the work.

[0025] The device can stably clamp and fix the lower mold 10 by setting the molding seat 2 and the clamping plate 5. With the help of the ingenious cooperation between the mounting bracket 13 and the threaded rod 16, the upper mold 14 can be easily disassembled and installed. This design makes the device more efficient and convenient in quickly disassembling and assembling the lower mold 10 and the upper mold 14. Therefore, the device can flexibly change the mold to match the style of the required parts according to actual production needs, so as to easily produce parts of different styles and specifications. This function greatly improves the applicability of the device, enabling it to better adapt to diverse production needs and enhance its versatility and flexibility in different production scenarios.

[0026] The working principle and usage process of this utility model are as follows: A suitable lower mold 10 is placed inside the forming base 2, and the support plate 18 is inserted into the inner side of the sliding groove at the bottom of the lower mold 10. The motor is started, driving the crown gear 9 to rotate the spur gear ring 8. The spur gear ring 8, through meshing with the driven crown gear 7, causes the inner thread sleeve 3 to rotate. When the inner thread sleeve 3 rotates, the lead screw 4 moves axially under the action of the inner thread of the inner thread sleeve 3, pushing the clamping plate 5 inward, so that the retaining ball 6 is embedded in the retaining groove of the lower mold 10, clamping and fixing the lower mold 10. The connecting block 15 above the upper mold 14 is inserted into the mounting bracket 13 from the bottom, and the threaded rod 16 is rotated. The blank is placed into the connecting block 15 to fix the upper mold 14. The blank is then placed into the lower mold 10. The first cylinder 12 is activated, pushing the mounting bracket 13 downward, which in turn moves the upper mold 14 downward and into the lower mold 10, squeezing the blank inside until it forms a support part. After forming, the first cylinder 12 retracts, moving the upper mold 14 upward to return to its initial position. The second cylinder 17 is activated, pushing the support plate 18 upward. The top of the support plate 18 pushes the bottom of the support part out of the lower mold 10. At the same time, the retaining ball 6 fixes the lower mold 10 to prevent it from shifting, thus completing the work.
