Technical Field
[0001] This application relates to the field of nut processing technology, and in particular to a thermoforming mold for left and right mounting nuts of an automotive battery pack. Background Technology
[0002] Currently, the left and right mounting nuts of automotive battery packs are important components used to fix electric vehicle battery packs. They are usually located on the left and right sides of the battery pack to ensure that the battery pack is stable and does not move during vehicle operation. When processing the mounting nuts, thermoforming molds are required to process and shape the nuts.
[0003] However, the existing thermoforming molds for the left and right mounting nuts of automotive battery packs have the following drawbacks: for example, after the nuts are processed and shaped using thermoforming molds, the inside of the nuts needs to be machined into the shape of threaded grooves, which makes demolding inconvenient. The formed nuts need to be manually rotated and removed, which is a cumbersome process and not convenient for quickly removing the formed nuts. Summary of the Invention
[0004] The purpose of this application is to facilitate the rapid demolding and removal of the nut after it has been molded.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a thermoforming mold for left and right mounting nuts of an automotive battery pack, comprising a bracket, a lower mold fixedly connected to the upper surface of the bracket, a plate frame fixedly connected to the inner wall of the bracket, a telescopic rod fixedly connected to the upper surface of the plate frame, a connecting plate fixedly connected to the output end of the telescopic rod, a demolding assembly provided on the upper surface of the connecting plate, the demolding assembly comprising three sets, the demolding assembly comprising a demolding rod, a threaded mold, and a limiting rod, the demolding rod being fixedly connected to the upper surface of the connecting plate, a limiting rod being rotatably connected inside the demolding rod, a threaded mold being fixedly connected to the upper end of the limiting rod, a lower mold groove being provided inside the lower mold, three lower mold grooves being provided, the threaded mold being movably connected inside the lower mold groove, a nut body being movably connected inside the lower mold groove, and the threaded mold being threadedly connected inside the nut body.
[0006] Further preferably, a pump body one is fixedly connected to the outer wall of the lower mold, a cooling pipe is fixedly connected to the output end of the pump body one, the cooling pipe is fixedly connected to the inside of the lower mold, a pump body two is fixedly connected to the outer wall of the lower mold, and the input end of the pump body two is fixedly connected to the inside of the cooling pipe.
[0007] Further preferably, the upper surface of the lower mold is fixedly connected with a support rod, and four support rods are provided, with a top plate fixedly connected to the top of each support rod.
[0008] In a further preferred embodiment, a cylinder is fixedly connected to the upper surface of the top plate, a fixed frame is fixedly connected to the output end of the cylinder, an upper mold is fixedly connected to the lower end of the fixed frame, and the upper mold is slidably connected to the outer wall of the support rod.
[0009] Further preferably, the upper mold has an upper mold groove inside, and there are three upper mold grooves, which are movably connected to the outer wall of the nut body.
[0010] Further preferably, an injection tube is fixedly connected inside the upper mold, and an injection hole is opened inside the upper mold.
[0011] Compared with the prior art, the beneficial effects of this application are as follows:
[0012] (1) The telescopic rod drives the connecting plate to move down, the connecting plate moves down and drives the three sets of demolding components to move down, the connecting plate drives the demolding rod to move down, the demolding rod moves down and drives the limiting rod and the threaded mold to move down. During the process of the threaded mold moving down, it is connected to the internal thread of the nut body, which causes the limiting rod to rotate within the demolding rod. After the threaded mold moves down out of the lower mold, it slides up and can remove the nut body, which facilitates the effect of quick demolding.
[0013] (2) The cylinder drives the fixed frame and the upper mold to move down and press against the upper surface of the lower mold. The heated processing nut material is injected into the upper mold groove and the lower mold groove through the injection hole using the injection tube. Combined with pump body one and pump body two, the coolant circulates in the cooling tube, so that the interior of the lower mold is cooled quickly, thereby making the nut body quickly formed and assisting in the demolding effect.

A telescopic rod 4 is fixedly connected to the upper surface of the plate frame 3. A connecting plate 5 is fixedly connected to the output end of the telescopic rod 4. A demolding assembly is provided on the upper surface of the connecting plate 5. The demolding assembly has three sets, which facilitate demolding by moving downwards. The demolding assembly includes a demolding rod 6, a threaded mold 7, and a limiting rod 8. The demolding rod 6 is fixedly connected to the upper surface of the connecting plate 5. The limiting rod 8 is rotatably connected inside the demolding rod 6. The limiting rod 8 limits the rotation inside the demolding rod 6, assisting in moving the threaded mold 7 downwards. The upper end of the limiting rod 8 is fixed... The lower mold 2 is fixedly connected to a threaded mold 7. The interior of the lower mold 2 has three lower mold grooves 9. The threaded mold 7 is movably connected inside the lower mold groove 9. A nut body 10 is movably connected inside the lower mold groove 9. The threaded mold 7 is threadedly connected inside the nut body 10. A pump body 11 is fixedly connected to the outer wall of the lower mold 2. The input end of the pump body 11 is connected to a cooling box. The output end of the pump body 11 is fixedly connected to a cooling pipe 12. The cooling pipe 12 is fixedly connected inside the lower mold 2. A second pump body 13 is fixedly connected to the outer wall of the lower mold 2. The input end of the second pump body 13 is fixedly connected to the interior of the cooling pipe 12. The output end of the second pump body 13 is connected to the cooling box, thus realizing the circulation of coolant.
[0025] A support rod 14 is fixedly connected to the upper surface of the lower mold 2. Four support rods 14 are provided. A top plate 15 is fixedly connected to the top of the support rod 14. A cylinder 16 is fixedly connected to the upper surface of the top plate 15. A fixing frame 17 is fixedly connected to the output end of the cylinder 16. An upper mold 18 is fixedly connected to the lower end of the fixing frame 17. The upper mold 18 is slidably connected to the outer wall of the support rod 14. The support rod 14 limits the upper mold 18. An upper mold groove 19 is provided inside the upper mold 18. Three upper mold grooves 19 are provided. The upper mold grooves 19 are movably connected to the outer wall of the nut body 10. An injection tube 20 is fixedly connected inside the upper mold 18. The inlet end of the injection tube 20 is connected to the nut raw material heating device. An injection hole 21 is provided inside the upper mold 18. The injection hole 21 facilitates the injection of raw material into the upper mold groove 19 and the lower mold groove 9.
[0026] Working principle: In use, first connect the inlet end of the injection tube 20 to the nut material heating device, and fix the input end of pump body 11 and the output end of pump body 2 13 inside the cooling box. First, start the cylinder 16 to drive the fixed frame 17 to move down. The movement of the fixed frame 17 drives the upper mold 18 to move down. The upper mold 18 moves down and fits with the lower mold 2, so that the three upper mold grooves 19 are aligned with the three lower mold grooves 9. The heated nut material is injected into the upper mold 18 through the injection tube 20, and then enters the upper mold grooves 19 and lower mold grooves 9 through the injection hole 21. After the injection is completed, start pump body 11 and pump body 2 13. Pump body 11 delivers coolant into the cooling pipe 12, and pump body 2 13 draws coolant out of the cooling pipe 12 and delivers it back into the cooling box, so that the coolant circulates inside the cooling pipe 12. The cooling pipe 12 is used to quickly cool the interior of the lower mold 2, which allows the nut body 10 to be formed quickly. After forming, the cylinder 16 is activated to move the fixed frame 17 and the upper mold 18 upward. Then, the telescopic rod 4 is activated to move the connecting plate 5 downward. During the downward movement of the connecting plate 5, the three sets of demolding components are moved downward. The connecting plate 5 moves the demolding rod 6 downward. During the downward movement of the demolding rod 6, the limiting rod 8 and the threaded mold 7 are moved downward. The threaded mold 7 is threadedly connected to the interior of the nut body 10, which causes the threaded mold 7 to rotate during the downward movement. During the rotation of the threaded mold 7, the rotation is limited by the limiting rod 8 and is inside the demolding rod 6. When the threaded mold 7 slides out of the interior of the lower mold 2, the nut body 10 can be slid upward to remove it, completing the demolding work and achieving the effect of easy demolding without the need for manual rotation of the nut body 10 for demolding.
