Detailed Implementation
[0020] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0021] like Figure 1 - Figure 4 As shown, the anti-overflow sealing structure of the copper busbar plastic mold provided in this embodiment includes a slider insert 1 and a slider seat 2 disposed on one side of the slider insert 1. A copper busbar frame 3 is disposed on the slider insert 1, and a plurality of copper busbars 4 are embedded inside the copper busbar frame 3. A first inclined ejector 5, a second inclined ejector 6, and a third inclined ejector 7 are disposed at one end of the plurality of copper busbars 4. The first inclined ejector 5, the second inclined ejector 6, and the third inclined ejector 7 are respectively corresponding to the plurality of copper busbars 4, and a push plate 8 is fixedly connected to the end of the first inclined ejector 5, the second inclined ejector 6, and the third inclined ejector 7 away from the plurality of copper busbars 4. Two springs 9 are disposed on one side of the push plate 8. When the mold is closed, the slider insert 1 moves closer to the slider seat 2. At this time, the first inclined ejector 5, the second inclined ejector 6, and the third inclined ejector 7 move towards the slider insert 1 under the action of the mold closing force. As the mold closing action progresses, the gap between the copper busbar 4 and each of the inclined ejectors gradually decreases, causing the sides of the first inclined ejector 5, the second inclined ejector 6, and the third inclined ejector 7 to fit tightly against the corresponding edges of several copper busbars 4, forming a sealing surface. At this time, the push plate 8 moves with the inclined ejectors, and the two springs 9 are compressed, which prevents the molten plastic from overflowing from the edges of the copper busbar 4, effectively avoiding overflow. Moreover, because the movement of the inclined ejectors is guided and controllable, it can better ensure the accuracy and stability of the sealing compared to traditional sealing methods, allowing for better control of the overflow size. At the same time, it can also prevent damage to the copper busbar 4 during mold closing and opening, protecting the integrity of the copper busbar 4 surface, thereby improving the quality and yield of the copper busbar 4 plastic products.
[0022] Furthermore, such as Figure 1 - Figure 4As shown, the slider insert 1 has several inclined top grooves 10 inside. The first inclined top 5, the second inclined top 6, and the third inclined top 7 are slidably disposed inside the several inclined top grooves 10. The first inclined top 5, the second inclined top 6, and the third inclined top 7 are all provided with copper busbar grooves 13. The several copper busbar grooves 13 correspond to several copper busbars 4. The first inclined top 5, the second inclined top 6, and the third inclined top 7 slide inside the slider insert 1 through the inclined top grooves 10 to ensure the accuracy and stability of their movement direction during mold closing and opening. The copper busbar grooves 13 on the inclined tops correspond one-to-one with the copper busbars 4. When the mold is closed, the copper busbars 4 can be precisely embedded in the copper busbar grooves 13, making the contact between the inclined tops and the copper busbars 4 tighter and more fitting, further enhancing the sealing effect, and thus preventing the plastic melt from seeping out from the gap between the copper busbars 4 and the inclined tops.
[0023] Furthermore, such as Figure 1 - Figure 4 As shown, a first pin 11 is installed on the first inclined ejector 5, and a second pin 12 is installed on the second inclined ejector 6 and the third inclined ejector 7. The first pin 11 and the second pin 12 provide connection points for the first inclined ejector 5, the second inclined ejector 6 and the third inclined ejector 7 respectively, thereby assisting the inclined ejectors in accurate positioning and stable movement, ensuring accurate sealing action, and avoiding the displacement deviation of the inclined ejectors from affecting the anti-overflow sealing effect of the copper busbar plastic mold.
[0024] Furthermore, such as Figure 1 - Figure 4 As shown, a groove 14 is provided at one end of the slider insert 1 near the slider seat 2. The push plate 8 is slidably disposed inside the groove 14. One end of the two springs 9 is fixedly connected to the push plate 8, and the other end of the two springs 9 is fixedly connected to the slider seat 2. The groove 14 provides guidance and limit for the push plate 8, so that the push plate 8 can only slide in a specific direction. The two ends are connected by the springs 9, so that the energy is compressed and stored when the mold is closed, ensuring stable sealing of the inclined ejector. When the mold is opened, the energy is released to push the push plate 8 to reset and drive the inclined ejector to return to its original position, ensuring that the opening and closing actions of the anti-overflow sealing structure of the copper busbar plastic mold are continuous, accurate and reliable.
[0025] like Figure 1 - Figure 4 As shown, the principle of the anti-overflow sealing structure of the copper busbar plastic mold provided in this embodiment is as follows:
[0026] The copper strip grooves 13 on the first inclined ejector 5, the second inclined ejector 6, and the third inclined ejector 7 correspond one-to-one with several copper strips 4. When the mold is closed, the slider insert 1 moves closer to the slider seat 2. At this time, under the action of the mold closing force, the first inclined ejector 5, the second inclined ejector 6, and the third inclined ejector 7 move along the inclined ejector grooves 10 into the interior of the slider insert 1. As the mold closing action proceeds, the gap between the copper strips 4 and each inclined ejector gradually decreases, so that the sides of the first inclined ejector 5, the second inclined ejector 6, and the third inclined ejector 7 are tightly fitted with the corresponding edges of several copper strips 4 to form a sealing surface. At this time, the push plate 8 is displaced with the movement of the inclined ejectors, and the two springs 9 are compressed, which can prevent the plastic melt from overflowing from the edge of the copper strip 4, effectively avoiding the overflow phenomenon. At the same time, it can also avoid the copper strip 4 from being damaged during the mold closing and opening process, protecting the integrity of the surface of the copper strip 4, thereby improving the quality and yield of the copper strip 4 plastic products.
