Description

Technical Field

[0001] This utility model relates to the field of automotive parts mold production technology, and in particular to a fastening device suitable for producing automotive parts molds. Background Technology

[0002] With the rapid development of the automotive industry towards lightweighting and electrification, the design, materials, and production technologies of automotive parts are undergoing profound changes. The diverse demands of automotive parts are stimulating the development of the automotive parts mold industry. In the production process of automotive parts molds, the role of fastening devices is crucial, as they directly affect the positioning accuracy, processing stability, and production efficiency of the molds. The requirements for the precision and complexity of automotive parts molds are increasing day by day. Currently, the main method of fastening is still manual tightening. Multiple bolts are tightened in a specific sequence using a hydraulic wrench. When changing molds, the bolts must be loosened first, and then tightened again after mold replacement. This manual tightening process is not only time-consuming, but also requires different bolts for different mold sizes, impacting production efficiency. Furthermore, manual operation is insufficient for high-precision fastening tasks. Traditional fastening devices only provide the tightening effect and have no other functions. For example, during processing, the inside of the automotive parts mold needs to be carefully cleaned manually beforehand. After processing, demolding the automotive parts mold is very difficult, and in severe cases, it may even damage the mold. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fastening device suitable for producing automotive parts molds.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A fastening device suitable for producing automotive parts molds includes a support plate fixedly connected above a base, a U-shaped block slidably connected to the support plate via a tension assembly, a right-angle connecting rod slidably connected through the U-shaped block, a second rack fixedly connected to one end of the right-angle connecting rod, a first rotating shaft rotatably connected through the U-shaped block, a connecting plate fixedly connected to the outer side of the first rotating shaft, a fastening plate slidably connected to the outer side of the connecting plate, a spring fixedly connected between the fastening plate and the connecting plate, a second bevel gear rotatably connected to the upper end of the first rotating shaft, a one-way bearing fixedly connected between the second bevel gear and the first rotating shaft, a fixed sleeve rod fixedly connected through the upper end of the U-shaped block, a drive shaft rotatably connected to the upper end of the fixed sleeve rod, a second gear fixedly connected to the outer side of the drive shaft, a first bevel gear fixedly connected to the outer side of the drive shaft, the first bevel gear meshing with the second bevel gear, and the second gear meshing with the second rack.

[0018] Reference Figures 1-6A fastening device suitable for producing automotive parts molds includes a base 1, a support plate 2 fixedly connected above the base 1, a U-shaped block 7 slidably connected to the support plate 2 via a tension assembly, a right-angle connecting rod 16 slidably connected through the U-shaped block 7, a second rack 14 fixedly connected to one end of the right-angle connecting rod 16, a first rotating shaft 6 rotatably connected through the U-shaped block 7, a connecting plate 15 fixedly connected to the outer side of the first rotating shaft 6, a fastening plate 4 slidably connected to the outer side of the connecting plate 15, a spring 19 fixedly connected between the fastening plate 4 and the connecting plate 15, a second bevel gear 18 rotatably connected to the upper end of the first rotating shaft 6, a one-way bearing 17 fixedly connected between the second bevel gear 18 and the first rotating shaft 6, a fixing sleeve rod 11 fixedly connected through the upper end of the U-shaped block 7, a drive shaft 13 rotatably connected to the upper end of the fixing sleeve rod 11, and a drive shaft 13 rotatably connected to the outer side of the drive shaft 13. A second gear 14 is fixedly connected to the side of the transmission shaft 13, and a first bevel gear 12 is fixedly connected to the outside of the transmission shaft 13. The first bevel gear 12 meshes with the second bevel gear 18, and the second gear 14 meshes with the second rack 9. A wave groove 8 is opened on the side wall of the support plate 2, and one end of the right-angle connecting rod 16 extends into the wave groove 8 and slides in connection with the wave groove 8. When the U-shaped block 7 and the fastening plate 4 move towards each other, the second rack 9 moves up and down under the action of the right-angle connecting rod 16 and the wave groove 8. The second rack 9 drives the meshing second gear 14 to rotate back and forth. The second gear 14 drives the transmission shaft 13 and the first bevel gear 12 to rotate back and forth. The first bevel gear 12 drives the meshing second bevel gear 18 to rotate back and forth. During this process, under the action of the one-way bearing 17, the first rotating shaft 6 can only rotate in one direction. Figure 1 From this perspective, the first rotating shaft 6 and the fastening plate 4 are ultimately deflected towards the center, forming a fastening effect on the automotive parts mold.

[0019] The stretching assembly includes a second rotating shaft 23 that rotatably passes through the support plate 2. The second rotating shaft 23 is rotatably connected to a first gear 5. Two first racks 3 are slidably connected to the side wall of the support plate 2. The first gear 5 and the first racks 3 are meshed together. The first racks 3 are fixedly connected to the U-shaped block 7. A motor is fixedly connected to the outside of the support plate 2. The second rotating shaft 23 is fixedly connected to the output end of the motor. When it is necessary to perform a fastening operation on the automotive parts mold, the motor is started first. The motor drives the second rotating shaft 23 and the first gear 5 to rotate. The first gear 5 drives the two meshing first racks 3 to move closer to each other, thereby driving the U-shaped block and the fastening plate 4 to move as a whole.

[0020] An arc-shaped plate 10 is fixedly connected inside the U-shaped block 7. A wave track 21 is opened on the outside of the arc-shaped plate 10. A round rod 20 is fixedly connected to the outside of the fastening plate 4. The round rod 20 is slidably connected to the wave track 21. When the first rotating shaft 6 drives the fastening plate 4 to deflect through the connecting plate 15 and two springs 19, one end of the round rod 20 is always located inside the wave track 21. Therefore, the fastening plate 4 moves up and down relative to the first rotating shaft 6. The fastening plate 4 drives the fastened mold to shake. Before processing, the vibration of the automotive parts mold can automatically remove dust and other substances stuck inside the automotive parts mold, improving the cleanliness of the automotive parts mold. After processing, it can promote the demolding of the fastened mold.

[0021] A torsion spring 22 is fixedly connected between the connecting plate 15 and the U-shaped block 7, and the torsion spring 22 is sleeved on the outside of the first rotating shaft 6. When the fastening plate 4 and the fastened mold are relatively stationary, the first rotating shaft 6 can continue to move relative to the fastening plate 4 under the action of the torsion spring 22.

[0022] The outer side of the fastening plate 4 has multiple rubber protrusions, which can increase the friction between it and the mold and better fasten the mold.

[0023] In this utility model, when a fastening operation is required, the motor is started first. The motor drives the U-shaped block and the fastening plate 4 to move as a whole through the second rotating shaft 23, the first gear 5, and the first gear 5. During this process, the second rack 9 moves up and down. The second rack 9 drives the transmission shaft 13 and the first bevel gear 12 to rotate back and forth through the second gear 14. The first bevel gear 12 drives the meshing second bevel gear 18 to rotate back and forth. During this process, under the action of the one-way bearing 17, the first rotating shaft 6 can only rotate in one direction, forming a fastening effect on the automotive parts mold until the fastening plate 4 is completely against the automotive parts mold. Then the motor is turned off. Since there is a self-locking structure in the motor, the output shaft of the motor will not rotate when the motor is turned off. Therefore, the whole device is in a fixed state at this time. When the fastening plate 4 is deflected, the fastening plate 4 will move up and down relative to the first rotating shaft 6. The fastening plate 4 causes the fastened mold to shake. Before processing, the vibration of the automotive parts mold can automatically remove dust and other debris stuck inside the automotive parts mold, improving the cleanliness of the automotive parts mold. After processing, it can promote the demolding of the fastened mold.
