[0002] Copper busbar coating refers to the process of coating the surface of a copper busbar with a layer of insulating material. This treatment can improve the insulation performance of the copper busbar, enhance its withstand voltage, and protect it from external environmental corrosion, such as acid and alkali corrosion and mechanical damage, thereby extending the service life of the copper busbar. As new energy vehicles tend to be highly integrated and monolithic, the application of insert injection molding technology in the injection molding of copper busbar coating parts is becoming more and more widespread. This technology involves pre-fixing the copper busbar in the corresponding position of the mold, then performing injection molding after mold closing. After the mold is opened and cooled, the copper busbar is fixed inside the plastic product, thus obtaining a component with composite characteristics of copper busbar and plastic, which significantly promotes the integration and simplification of components.
[0003] Existing injection molding equipment for automotive copper busbars can only process copper busbars of fixed dimensions, which has certain limitations and results in low applicability of the equipment. In addition, it lacks components for positioning and fixing the copper busbars, which can easily cause the copper busbars to shift during injection molding, making the injection-molded copper busbars unacceptable. In order to solve the above problems, the inventor proposes an injection molding equipment for automotive copper busbars to solve the above problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example: Figure 1-6As shown, this utility model provides an injection molding equipment for automotive copper busbar coated plastic parts, including a fixed frame 1. A lower template 2 is fixedly installed at the bottom of the fixed frame 1, and an upper template 3 is slidably installed on the fixed frame 1. The side of the lower template 2 with a sliding frame 8 is wider than the upper template 3. Two symmetrically distributed first clamping plates 11 and second clamping plates 12 are slidably installed inside both the lower template 2 and the upper template 3. A sliding frame 8 is slidably installed on one side of the lower template 2, and a sliding block 20 is slidably installed inside the sliding frame 8. A support plate 22 is slidably inserted into the sliding block 20, and a first limiting bolt 21 is threaded into the sliding block 20. A fixed frame 24 is fixedly installed at one end of the support plate 22, and a second limiting bolt 25 is threaded into the fixed frame 24. According to the size of the mold, the lower mold 15 and the upper mold 26 can be centrally clamped and fixed on the lower template 2 and the upper template 3 respectively using the first clamping plate 11 and the second clamping plate 12. An injection nozzle 6 is fixedly installed on the mold 26. A through groove 5 is opened on the upper mold plate 3, and the injection nozzle 6 is located in the through groove 5. Then, one end of the copper busbar body 23 is inserted into the fixed frame 24 at one end of the support plate 22, and the second limit bolt 25 is tightened to fix it. Then, according to the position to be placed of the copper busbar body 23, the sliding frame 8 drives the support plate 22 and the copper busbar body 23 to move to the installation position. Then, the support plate 22 drives the copper busbar body 23 to move and adjust within the sliding block 20. After the adjustment is completed, the first limit bolt 21 is tightened to fix it. Then, according to the height of the lower mold 15, the height of the mold is higher than the wall plate of the mold plate. The sliding block 20 drives the support plate 22 to slide and descend within the sliding frame 8 to adjust, thereby completing the positioning and fixing of the copper busbar body 23. A slot is opened on one side of the lower mold 15, and the copper busbar body 23 can be locked in the slot to facilitate the sealing and fitting of the upper mold 26 and the lower mold 15.
[0022] Both the lower template 2 and the upper template 3 are rotatably installed with bidirectional lead screws 16, and the bidirectional lead screws 16 are threaded into one end of the corresponding two first clamping plates 11. One end of each of the two bidirectional lead screws 16 is fixedly installed with a first knob 7. Two symmetrically distributed pull rods 13 are inserted through both sides of the lower template 2 and the upper template 3, and one end of the pull rod 13 is fixedly connected to the corresponding second clamping plate 12. Each of the eight pull rods 13 is fitted with a spring 14, and one end of the spring 14 is in contact with the corresponding second clamping plate 12.
[0023] By adopting the above technical solution, firstly, the pull rod 13 pulls the corresponding two second clamping plates 12 away from each other and compresses the spring 14. Then, the lower mold 15 and the upper mold 26 are placed into the lower template 2 and the upper template 3 respectively, and the pull rod 13 is released. Using the rebound force of the spring 14, the second clamping plates 12 are centered and positioned on the mold. The first knob 7 drives the bidirectional lead screw 16 to rotate. The second bidirectional lead screw 16 drives the corresponding two first clamping plates 11 to slide closer to each other and clamp and fix the mold in the center, thereby clamping and fixing the lower mold 15 and the upper mold 26 in the lower template 2 and the upper template 3 respectively.
[0024] A first threaded rod 9 is rotatably installed on one side of the lower template 2, and the first threaded rod 9 is threadedly inserted into the bottom end of the sliding frame 8. A second knob 10 is fixedly installed at one end of the first threaded rod 9. A second threaded rod 18 is rotatably installed inside the sliding frame 8. A third knob 17 is fixedly installed at the top end of the second threaded rod 18. A threaded sleeve 19 is fixedly installed on the upper surface of the sliding block 20, and the second threaded rod 18 is threadedly inserted into the threaded sleeve 19.
[0025] By adopting the above technical solution, the second knob 10 drives the first threaded rod 9 to rotate, the first threaded rod 9 drives the sliding frame 8 to move, the third knob 17 drives the second threaded rod 18 to rotate, and the second threaded rod 18 drives the sliding block 20 to slide and rise and fall within the sliding frame 8 through the threaded sleeve 19.
[0026] A cylinder 4 is fixedly installed at the top of the fixed frame 1, and the output end of the cylinder 4 is fixedly connected to the top of the upper template 3.
[0027] By adopting the above technical solution, the cylinder 4 drives the upper template 3 to descend, so that the bottom end of the upper mold 26 and the top end of the lower mold 15 are sealed and fitted together to complete the mold closing.
[0028] Working principle: When using this utility model, firstly, the pull rod 13 pulls the corresponding two second clamping plates 12 away from each other and squeezes the spring 14. Then, the lower mold 15 and the upper mold 26 are placed into the lower template 2 and the upper template 3 respectively, and the pull rod 13 is released. The rebound force of the spring 14 makes the second clamping plates 12 center the mold. The first knob 7 drives the bidirectional lead screw 16 to rotate. The second bidirectional lead screw 16 drives the corresponding two first clamping plates 11 to slide closer to each other and center the mold for clamping and fixing. Thus, the lower mold 15 and the upper mold 26 are clamped and fixed in the lower template 2 and the upper template 3 respectively.
[0029] Next, insert one end of the copper busbar body 23 into the fixing frame 24 at one end of the support plate 22, and tighten the second limiting bolt 25 to fix it. Then, according to the position where the copper busbar body 23 needs to be placed, use the second knob 10 to drive the first threaded rod 9 to rotate. The first threaded rod 9 drives the sliding frame 8 to move. The sliding frame 8 drives the support plate 22 and the copper busbar body 23 to the installation position. Then, make the support plate 22 drive the copper busbar body 23 to move and adjust within the sliding block 20. After the adjustment is completed, tighten the first limiting bolt 21 to fix it. Then, according to the height of the lower mold 15, make the sliding block 20 drive the support plate 22 to slide and descend within the sliding frame 8 to adjust, thereby completing the positioning and fixing of the copper busbar body 23.
[0030] Then, the cylinder 4 is used to drive the upper template 3 to descend, so that the bottom end of the upper mold 26 and the top end of the lower mold 15 are sealed and fitted to complete the mold closing. Injection is then performed through the injection nozzle 6. After injection molding, the cylinder 4 is used to drive the upper template 3 to rise and remove the molded workpiece.
