Description

Technical Field

[0001] The invention belongs to the technical field of hanging mechanisms, and in particular relates to a hanging mechanism for producing injection molds. Background Art

[0002] The production and manufacturing of new energy vehicles relies on the critical support of injection molds. As a vital tool for industrial molding, injection molds are widely used in the precision production of lightweight plastic parts in new energy vehicle manufacturing, including core components such as battery housing assemblies, charging port covers, instrument panels, interior trims, and various electronic component housings. With the increasing demand for lightweight and integrated new energy vehicles, high-precision, high-temperature-resistant injection molds have become core equipment for ensuring product quality and production efficiency, driving the innovative application of new engineering plastics and intelligent injection molding processes in the new energy vehicle sector.

[0003] In the production of injection molds for new energy vehicles, they need to be lifted to move to other places or install. Since lifting usually uses ropes accompanied by hooks for transportation, due to the existence of ropes and inertia, it is necessary to reduce the speed of movement. At the same time, a hanging ring is connected to the mold and a hook is hung, which will seriously reduce the lifting rate and thus reduce the production efficiency of the injection mold.

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0023] Example 1: Reference Figures 1-8 A hanging mechanism for injection mold production includes a transverse track 1, on which an electric slide 2 is slidably installed, and the electric slide 2 can move horizontally left and right on the transverse track 1. It also includes: a longitudinally arranged lifting device 3, which is longitudinally fixedly installed on the electric slide 2, wherein the telescopic end of the lifting device 3 is fixedly connected to an inverted U-shaped frame 4, and both sides of the inverted U-shaped frame 4 are rotatably installed with a rotating shaft 5; a rectangular frame 11, which is fixedly installed between the two rotating shafts 5, wherein both sides of the rectangular frame 11 are fixedly installed with a transversely arranged telescopic device 7, the lifting device 3 and the telescopic device 7 are both hydraulic cylinders, and the telescopic ends of the two sets of telescopic devices 7 are fixedly installed with a splint 8, and the inverted U-shaped frame 4 is provided with a flipping part that drives the rotating shaft 5 to rotate 90°.

[0024] Specifically, when the injection mold needs to be moved for processing, the inverted U-shaped frame 4 is driven downward by the lifting device 3 until the inverted U-shaped frame 4 drives the two clamps 8 to move to both sides of the injection mold, and then the two clamps 8 are driven close to each other by the telescopic device 7 until the two clamps 8 clamp the injection mold, and then the inverted U-shaped frame 4 is driven upward by the lifting device 3, and the two clamps 8 will lift the injection mold, and then the electric slide 2 is moved horizontally on the transverse track 1 to realize the movement of the injection mold. During the movement, there is no need to use ropes to fix the injection mold , and the moving injection mold is not prone to shaking, which significantly improves the lifting rate of the injection mold and indirectly improves the processing efficiency of the injection mold. When the inverted U-shaped frame 4 is lifted upward, the flipping part will drive the rotating shaft 5 to rotate, and the rotating shaft 5 will drive the rectangular frame 11 to rotate 90°. The rectangular frame 11 will drive the injection mold to rotate 90° through the two splints 8. The injection mold is not easy to fall out of the rectangular frame 11, which improves the safety during the lifting process, and can also dump out some processing debris in the injection mold, which is convenient for subsequent further processing of the injection mold.

[0025] Example 2: Reference Figures 1-6 , a hanging mechanism for injection mold production, which is basically the same as Example 1, further comprising: The above-mentioned flipping part includes a driven gear 9 fixedly mounted on the end of the rotating shaft 5, and a rack 10 is fixedly connected to the outer wall of the fixed end of the lifting device 3. When the inverted U-shaped frame 4 is lifted upward, the driven gear 9 will sweep over the rack 10.

[0026] Specifically, when the inverted U-shaped frame 4 is lifted upward, the inverted U-shaped frame 4 will also drive the driven gear 9 to move upward, and the driven gear 9 will sweep across the rack 10, and the rack 10 will drive the driven gear 9 to rotate, and the driven gear 9 will rotate through the rotating shaft 5, and the rotating shaft 5 will drive the rectangular frame 11 to rotate 90°, and the rectangular frame 11 will drive the injection mold to rotate 90° through the two splints 8. When the lifting device 3 places the injection mold to the destination, the downward-moving rectangular frame 11 will drive the driven gear 9 to sweep across the rack 10 again in the opposite direction, and the driven gear 9 will drive the rectangular frame 11 to flip 90° in the opposite direction, so that the injection mold is restored to a horizontal state again.

[0027] In practice, in order to ensure that the rotating shaft 5 does not rotate automatically under the action of gravity of the injection mold, a brake assembly can be installed at the shaft end of the rotating shaft 5. The brake assembly mainly consists of a brake disc and a brake assembly. When the rotating shaft 5 does not need to rotate, it is used to temporarily fix the rotating shaft 5 to prevent the rotating shaft 5 from rotating.

[0028] In practice, C-shaped frames 6 are fixedly connected to both sides of the rectangular frame 11, the rotating shaft 5 is fixedly connected to the C-shaped frames 6, and the C-shaped frames 6 will block the fixed end of the telescopic device 7. Therefore, the C-shaped frames 6 can improve the stability of the rotating shaft 5 on the one hand, and effectively protect the telescopic device 7 on the other hand.

[0029] Example 3: Reference Figure 1-Figure 5 , a hanging mechanism for injection mold production, which is basically the same as Example 2, further comprising: The upper and lower sides of the above-mentioned splint 8 are provided with device grooves 12, and L-shaped plates 14 are rotatably installed in the two device grooves 12 through the rotating rod 13. A linkage part is provided on the splint 8. When the rectangular frame 11 rotates following the rotating shaft 5, the linkage part will drive the rotating rod 13 to rotate. The linkage part includes a transmission shaft 15 rotatably connected to the outer wall of the splint 8, and a worm 16 is fixedly installed at one end of the transmission shaft 15. A worm wheel 17 meshing with the worm 16 is fixedly installed at the shaft end of the rotating rod 13, and a long rod-shaped gear 18 is fixedly installed at the other end of the transmission shaft 15. A ring gear 19 meshing with the long rod-shaped gear 18 is fixedly installed on the inverted U-shaped frame 4.

[0030] Specifically, when the rectangular frame 11 flips, the rectangular frame 11 will drive the long rod-shaped gear 18 to flip synchronously through the splint 8, and the long rod-shaped gear 18 will roll along the ring gear 19, and the ring gear 19 will drive the long rod-shaped gear 18 to rotate, and the long rod-shaped gear 18 will drive the worm 16 to rotate through the transmission shaft 15, and the worm 16 will drive the worm wheel 17 to rotate, and the worm wheel 17 will drive the rotating rod 13 to rotate, and the rotating rod 13 will drive the L-shaped plate 14 to flip out of the device groove 12, and the upper and lower groups of L-shaped plates 14 will be buckled at the upper and lower ends of the injection mold respectively, so that the injection mold is fixed more firmly, further improving the stability of the injection mold during lifting.

[0031] The two clamping plates 8 and the two L-shaped plates 14 are both provided with anti-slip grooves on their bearing surfaces, and the anti-slip grooves can improve the stability when clamping the injection mold.

[0032] Example 4: Reference Figures 1-8 , a hanging mechanism for injection mold production, which is basically the same as Example 3, further comprising: A cavity 20 is provided inside the above-mentioned L-shaped plate 14, and an exhaust hole 21 connected to the cavity 20 is opened on the outer wall of the L-shaped plate 14. An air supply part for conveying air to the cavity 20 is provided on the inverted U-shaped frame 4, and the air supply part includes a cross frame 24 fixedly connected to the fixed end of the lifting device 3. A telescopic airbag 25 is installed between the inverted U-shaped frame 4 and the cross frame 24. The telescopic airbag 25 is fixedly connected to the intake pipe 26 and the exhaust pipe 27 connected to it, and a one-way valve is fixedly installed in the intake pipe 26 and the exhaust pipe 27. The exhaust pipe 27 is connected to the cavity 20 through a connecting part. The connecting part includes an inner hole 22 opened at the axial end of the rotating shaft 5, and the end of the exhaust pipe 27 is rotatably connected to the port of the inner hole 22. The outer wall of the rotating shaft 5 is fixedly connected to a hose 23 connected to the inner hole 22, and the end of the hose 23 extends into the cavity 20.

[0033] Specifically, when the inverted U-shaped frame 4 is lifted upward, the inverted U-shaped frame 4 will squeeze the telescopic airbag 25, and the telescopic airbag 25 will discharge the internal air through the exhaust pipe 27 and transport it to the inner hole 22, and then it will be transported to the cavity 20 through the hose 23, and finally discharged from the exhaust hole 21. At this time, the flipped L-shaped plate 14 will drive the exhaust hole 21 to sweep across the upper and lower surfaces of the injection mold, so that the debris in the injection mold can fall out more easily. When the inverted U-shaped frame 4 moves downward, it will stretch the telescopic airbag 25, and negative pressure will be generated inside the telescopic airbag 25, and air will be sucked in through the suction pipe 26.

[0034] Example 5: Reference Figures 1-8 A method for hanging an injection mold for production, comprising the following steps: S1, the inverted U-shaped frame 4 drives the two clamping plates 8 to move to both sides of the injection mold; S2, making two clamps 8 clamp the injection mold; S3, using the two clamping plates 8 to lift the injection mold upwards; S4, while the injection mold is being lifted, the rectangular frame 11 and the injection mold are flipped 90°; S5. While the rectangular frame 11 is flipped 90°, the two upper and lower sets of L-shaped plates 14 are buckled at the upper and lower ends of the injection mold respectively; S6, the electric slide 2 drives the two clamping plates 8 and the injection mold to move horizontally to the destination; S7, the inverted U-shaped frame 4 drives the two clamping plates 8 to move downward until the injection mold is placed at the destination.

[0035] According to the present invention, when the injection mold needs to be moved for processing, the inverted U-shaped frame 4 is driven downward by the lifting device 3 until the inverted U-shaped frame 4 drives the two clamps 8 to move to both sides of the injection mold, and then the two clamps 8 are driven close to each other by the telescopic device 7 until the two clamps 8 clamp the injection mold, and then the inverted U-shaped frame 4 is driven upward by the lifting device 3, and the two clamps 8 will lift the injection mold, and then the electric slide 2 is moved horizontally on the transverse track 1 to realize the movement of the injection mold. During the movement, there is no need to use ropes to fix the injection mold, and the moving injection mold is not prone to shaking, which significantly improves the lifting rate of the injection mold and indirectly improves the processing efficiency of the injection mold.

[0036] When the inverted U-shaped frame 4 is lifted upward, the inverted U-shaped frame 4 will also drive the driven gear 9 to move upward, and the driven gear 9 will sweep across the rack 10, and the rack 10 will drive the driven gear 9 to rotate, and the driven gear 9 will rotate through the rotating shaft 5, and the rotating shaft 5 will drive the rectangular frame 11 to rotate 90°, and the rectangular frame 11 will drive the injection mold to rotate 90° through the two splints 8, so that the injection mold is not easy to fall out of the rectangular frame 11, which improves the safety during the lifting process, and can also dump out some processing debris in the injection mold, which is convenient for subsequent further processing of the injection mold. When the lifting equipment 3 places the injection mold to the destination, the downward-moving rectangular frame 11 will drive the driven gear 9 to sweep across the rack 10 again in the opposite direction, and the driven gear 9 will drive the rectangular frame 11 to flip 90° in the opposite direction, so that the injection mold is restored to a horizontal state again.

[0037] When the rectangular frame 11 flips over, the rectangular frame 11 will drive the long rod-shaped gear 18 to flip synchronously through the splint 8, and the long rod-shaped gear 18 will roll along the ring gear 19, and the ring gear 19 will drive the long rod-shaped gear 18 to rotate, and the long rod-shaped gear 18 will drive the worm 16 to rotate through the transmission shaft 15, and the worm 16 will drive the worm wheel 17 to rotate, and the worm wheel 17 will drive the rotating rod 13 to rotate, and the rotating rod 13 will drive the L-shaped plate 14 to flip out of the device groove 12, and the upper and lower sets of L-shaped plates 14 will be buckled at the upper and lower ends of the injection mold respectively, so that the injection mold is fixed more firmly, further improving the stability of the injection mold during lifting.

[0038] When the inverted U-shaped frame 4 is lifted upward, the inverted U-shaped frame 4 will squeeze the telescopic airbag 25, and the telescopic airbag 25 will discharge the internal air through the exhaust pipe 27 and transport it to the inner hole 22, and then transport it to the cavity 20 through the hose 23, and finally be discharged from the exhaust hole 21. At this time, the flipped L-shaped plate 14 will drive the exhaust hole 21 to sweep across the upper and lower surfaces of the injection mold, so that the debris in the injection mold can fall out more easily. When the inverted U-shaped frame 4 moves downward, it will stretch the telescopic airbag 25, and negative pressure will be generated inside the telescopic airbag 25, and air will be sucked in through the suction pipe 26.
