Description

Technical Field

[0001] This invention relates to injection molding equipment, and more particularly to a flexible and rigid copper busbar support mechanism, an injection molding processing device, and an injection molding processing method. Background Technology

[0002] In the field of electrical equipment, copper busbars are core conductive components. The combination of flexible and rigid copper busbars, balancing structural strength and installation flexibility, is widely used in various equipment. Their support mechanisms directly affect the equipment's conductivity, operational reliability, and production costs. Currently, existing flexible and rigid copper busbar support mechanisms have several drawbacks: flexible copper busbars lack effective limiting due to their flexibility, making precise positioning difficult and prone to misalignment; rigid copper busbars, due to improper positioning during injection molding, are prone to misalignment and copper leakage, affecting quality and increasing costs; there is no dedicated positioning structure during assembly, making the assembly of copper busbars and nuts cumbersome, time-consuming, and difficult to adapt to large-scale production; furthermore, copper busbars are easily scratched during assembly, reducing their performance and service life. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a soft and hard copper busbar support mechanism, injection molding device and injection molding method that can achieve precise positioning, optimize injection molding effect, improve assembly efficiency and protect copper busbars, in order to address the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] A flexible and rigid copper busbar support mechanism includes a first bracket, a second bracket, a plurality of first copper busbars, and a plurality of second copper busbars. The first bracket has a plurality of vertically extending slots, through which the first copper busbars pass one by one, and the upper ends of the first copper busbars are engaged with the first bracket. The second bracket is stacked on top of the first bracket, and the bottom of the second bracket has a plurality of slots, in which the upper ends of the first copper busbars are fitted one by one, and the upper ends of the first copper busbars are tightly engaged with the slots. The second bracket has a plurality of nut slots, and the plurality of second copper busbars are all attached to the second bracket. The second copper busbars are provided with nuts, which are fitted one by one into the nut slots.

[0006] Preferably, the first copper busbar includes a lower copper busbar and an inverted U-shaped copper busbar. The upper end of the lower copper busbar is connected to one end of the inverted U-shaped copper busbar, and the connection between the two is located in the slot. A straight convex ridge is formed on the first bracket. The straight convex ridge is provided with multiple protrusions. The protrusions are arranged adjacent to the slot. The inverted U-shaped copper busbar is fastened to the protrusions.

[0007] Preferably, the other end of the inverted U-shaped copper busbar has an upper copper busbar extending laterally toward the first bracket.

[0008] Preferably, the upper end of the lower copper busbar has a tenon, and one end of the inverted U-shaped copper busbar has a mortise, with the tenon embedded in the mortise and the two tightly connected.

[0009] Preferably, the lower copper busbar is a soft copper busbar, and the inverted U-shaped copper busbar is a hard copper busbar.

[0010] Preferably, the lower copper busbar is provided with multiple connection holes.

[0011] Preferably, the first support includes a downwardly extending sheath, through which the slot extends.

[0012] Preferably, the second bracket has multiple copper busbar slots, and multiple second copper busbars are respectively embedded in the multiple copper busbar slots.

[0013] An injection molding apparatus includes a mold core, wherein a flexible and rigid copper busbar support mechanism is provided within the mold core.

[0014] An injection molding method, based on a mold core and the aforementioned soft and hard copper busbar support mechanism, includes the following steps: Step S1, passing the first copper busbar through the corresponding slots, so that the upper end of the first copper busbar engages with the first bracket; Step S2, stacking the second bracket on top of the first bracket, so that the upper ends of the first copper busbars are correspondingly embedded in the slots, and keeping the upper ends of the first copper busbars tightly engaged with the slots; Step S3, embedding the nuts on the second copper busbars into the corresponding nut slots, and attaching the second copper busbars to the second bracket; Step S4, assembling the first bracket, the second bracket, multiple first copper busbars, and multiple second copper busbars, and placing them in the mold core for injection molding.

[0015] The flexible and rigid copper busbar support mechanism disclosed in this invention, during assembly, firstly, the first copper busbars are passed through the corresponding slots one by one, so that the upper ends of the first copper busbars are engaged with the first bracket. Then, the second bracket is stacked on top of the first bracket, so that the upper ends of the first copper busbars are embedded in the corresponding slots, and the upper ends of the first copper busbars are kept in close contact with the slots.

[0017] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0018] This invention discloses a flexible and rigid copper busbar support mechanism, combined with Figures 1 to 9 As shown, it includes a first support 1, a second support 2, multiple first copper busbars 3 and multiple second copper busbars 4. The first support 1 has multiple vertically extending slots 10. The first copper busbars 3 pass through the slots 10 one by one, and the upper ends of the first copper busbars 3 are engaged with the first support 1. The second support 2 is stacked on top of the first support 1. The bottom of the second support 2 has multiple slots 20. The upper ends of the first copper busbars 3 are embedded in the slots 20 one by one, and the upper ends of the first copper busbars 3 are tightly engaged with the slots 20. The second support 2 has multiple nut slots 21. The multiple second copper busbars 4 are all attached to the second support 2. The second copper busbars 4 have nuts 40, and the nuts 40 are embedded in the nut slots 21 one by one.

[0019] During assembly, the first copper busbars 3 are first passed through the corresponding slots 10, with their upper ends engaging with the first bracket 1. Then, the second bracket 2 is stacked on top of the first bracket 1, with the upper ends of the first copper busbars 3 correspondingly embedded in the slots 20, ensuring a tight fit between the upper ends of the first copper busbars 3 and the slots 20. Next, the nuts 40 on the second copper busbars 4 are correspondingly embedded in the nut slots 21, and the second copper busbars 4 are attached to the second bracket 2. Finally, the first bracket 1, the second bracket 2, the multiple first copper busbars 3, and the multiple second copper busbars 4 are assembled and placed in the mold core for injection molding. Compared to the technical defects of existing technologies, such as the inability to position soft copper busbars, the easy leakage of copper during injection molding of hard copper busbars, long assembly cycles, and easy scratching of copper busbars, this invention achieves precise positioning of both soft and hard copper busbars, optimizes the injection molding effect, improves assembly efficiency, and protects the copper busbars from damage, thus better meeting application requirements.

[0020] In a preferred embodiment, the first copper busbar 3 includes a lower copper busbar 30 and an inverted U-shaped copper busbar 31. The upper end of the lower copper busbar 30 is connected to one end of the inverted U-shaped copper busbar 31, and the connection between the two is located in the slot 10. A straight protrusion 12 is formed on the first support 1. The straight protrusion 12 is provided with a plurality of protrusions 11. The protrusions 11 are arranged adjacent to the slot 10, and the inverted U-shaped copper busbar 31 is fastened to the protrusions 11.

[0021] In the above structure, by setting the straight protrusion 12, a supporting base can be provided for the inverted U-shaped copper busbar 31, thereby achieving the effect of the first copper busbar 3 and the first bracket 1 engaging. At the same time, by setting multiple protrusions 11, the inverted U-shaped copper busbar 31 can be fastened one by one, which can reliably support and position the inverted U-shaped copper busbar 31.

[0022] In this embodiment, please refer to Figure 2 and Figure 3 The other end of the inverted U-shaped copper busbar 31 forms an upper copper busbar 32 that extends laterally toward the first support 1.

[0023] In a preferred embodiment, the upper end of the lower copper busbar 30 has a tenon 33, and one end of the inverted U-shaped copper busbar 31 has a mortise 34. The tenon 33 is fitted into the mortise 34, and the two are tightly connected. Further, the lower copper busbar 30 is a soft copper busbar, and the inverted U-shaped copper busbar 31 is a hard copper busbar.

[0024] In the above structure, after the tenon 33 is embedded in the mortise 34, it can be fixed secondary by welding. Based on the mortise and tenon connection and the welding fixation relationship, the lower copper busbar 30 and the inverted U-shaped copper busbar 31 not only improve the reliability of physical and electrical connections, but also facilitate assembly and positioning. Furthermore, the secondary welding improves the connection performance between the soft and hard copper busbars. On this basis, in conjunction with the supporting and positioning functions of the first bracket 1 and the second bracket 2, the soft and hard copper busbars can be assembled efficiently.

[0025] To facilitate wiring, the lower copper busbar 30 is provided with multiple connection holes 35.

[0026] In a preferred embodiment, the first support 1 includes a downwardly extending sleeve 13, through which the slot 10 passes. The downwardly protruding sleeve 13 provides more adequate support and positioning for the first copper busbar 3.

[0027] In order to ensure the secure assembly of the second copper busbar 4, in this embodiment, the second bracket 2 is provided with a plurality of copper busbar slots 22, and the plurality of second copper busbars 4 are respectively embedded in the plurality of copper busbar slots 22.

[0028] Based on this, the present invention also discloses an injection molding processing device, which includes a mold core, wherein the mold core is provided with the soft and hard copper busbar support mechanism described above.

[0029] Furthermore, this invention also relates to an injection molding method, which is based on a mold core and the aforementioned soft and hard copper busbar support mechanism, combined with... Figures 1 to 9 As shown, the method includes the following steps: Step S1: Pass the first copper busbar 3 through the slot 10 one by one, so that the upper end of the first copper busbar 3 is engaged with the first bracket 1. Step S2: Stack the second bracket 2 on top of the first bracket 1, so that the upper ends of the first copper busbar 3 are embedded in the bayonet 20 one by one, and keep the upper ends of the first copper busbar 3 tightly fitted with the bayonet 20. Step S3: The nuts 40 on the second copper busbar 4 are fitted into the nut slots 21 one by one, and the second copper busbar 4 is attached to the second bracket 2. Step S4: After assembling the first bracket 1, the second bracket 2, multiple first copper busbars 3 and multiple second copper busbars 4, place them in the mold core for injection molding.

[0030] In the above method, during assembly, the first copper busbar 3 is first passed through the slots 10 of the first bracket 1 one by one to achieve a snap-fit ​​engagement. Then, the second bracket 2 is stacked on top of the first bracket 1, so that the upper end of the first copper busbar 3 is precisely embedded in the snap-fit ​​20 and tightly fitted. Subsequently, the second copper busbar 4 is fitted with the second bracket 2 through the corresponding embedding of the nut 40 and the nut insert 21. Finally, the whole assembly is placed into the mold core for injection molding. Based on the above assembly process, the core defects of the prior art are effectively solved, namely: the dual limiting of the slots 10 and the snap-fit ​​20 achieves precise positioning of the first copper busbar 3, avoiding misalignment and copper leakage during injection molding; the nut insert 21 provides dedicated positioning for the second copper busbar 4 and the nut 40, simplifying the assembly process, significantly shortening the assembly cycle, and adapting to mass production; at the same time, the snap-fit ​​and embedding engagement method replaces the traditional cumbersome assembly, reduces the frictional contact between the copper busbar and the bracket, effectively avoids scratching the copper busbar, and ensures its conductivity and service life.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included within the scope of protection of the present invention.
