[0037] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0038] Unless otherwise specified or defined, the "first, second..." used in this article is merely used to distinguish names and does not represent a specific quantity or order.

[0039] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0041] Figure 1 Schematic diagram of dense bus duct. Compared with traditional bus duct, the copper bars in the busbar 10 of dense bus duct are arranged adjacently, not at intervals. The busbar 10 is more compact, and the copper bars in the joints 20 at both ends are arranged at intervals. There is a terminal 30 between the joint 20 and the busbar 10. The copper bars are bent in the terminal 30 and gradually spread out from the adjacent arrangement to form an at-interval arrangement. After casting with the existing casting mold, the cast dense bus duct obtained is a rectangular parallelepiped, which is large in size and has a high casting cost.

[0042] In view of the above problems, the utility model provides a casting mold for dense bus duct, which uses an end mold and a busbar mold to cast the two ends and the busbar of the bus duct respectively. After casting, the dense bus duct is dumbbell-shaped, smaller in size and lower in cost. In addition, the busbar mold is embedded in the end mold, which is easy to disassemble and improve the casting efficiency.

[0043] Figure 2 A stereoscopic diagram of the casting mold provided in this embodiment. The casting mold 100 mainly includes two terminal molds 110 and a busbar mold 120. The busbar mold 120 is a box body with openings at both ends, which is used to accommodate the busbar 10 and cast the busbar 10. The terminal mold 110 is similar to a box body, with openings at the top and two side ends, and the inside is a first cavity 111 and a second cavity 112 that are connected. The first cavity 111 is used to accommodate the end of the busbar mold 120, and the second cavity 112 is used to accommodate the terminal 30 of the dense bus duct and cast the terminal 30. Since the copper bars of the busbar 10 are arranged adjacently, the size of the busbar 10 is smaller than the size of the terminal 30. In order to save the casting material for casting the busbar 10, the width of the first cavity 111 is smaller than the width of the second cavity 112, the height of the busbar mold 120 is smaller than the height of the first cavity 111, and the size of the busbar 10 after casting is also smaller than the size of the terminal 30 after casting, so that the bus duct after casting is dumbbell-shaped. For the convenience of disassembly and assembly, the ends of the busbar mold 120 are embedded and installed in the first cavity 111. After the pouring is completed, the end molds 110 at both ends are taken out downward, and then the busbar mold 120 is taken out.

[0044] In one embodiment, the end mold 110 and the busbar mold 120 are both made of metal materials, such as stainless steel sheets, galvanized steel plates, aluminum plates, etc. After the casting is completed, only the end mold 110 is removed, and the busbar mold 120 is not removed. The busbar mold 120, as the outer shell of the busbar 10, can quickly conduct the heat of the castable to the outside, thereby improving the heat dissipation efficiency of the dense bus duct.

[0045] The casting mold 100 is also provided with a plugging plate 130, on which a slot 1301 is provided for the connector 20 of the bus duct to pass through, and is used to close the opening on the second cavity 112 and the end away from the first cavity 111 during casting. Since the plugging plate 130 needs to be removed after casting, the plugging plate 130 is embedded and installed in the second cavity 112 during casting, and is easy to remove after casting. In this embodiment, the plugging plate 130 includes an upper plate 1302 and a lower plate 1303, and the upper plate 1302 is provided with a plurality of first slots 1304 that penetrate the bottom surface of the upper plate 1302, and the first slots 1304 are arranged in a transverse interval. Correspondingly, the lower plate 1303 is also provided with a plurality of second grooves 1305 penetrating the top surface of the lower plate 1303, and the second grooves 1305 are arranged in a transverse interval, and each first groove 1304 at each position of the upper plate 1302 has a corresponding second groove 1305, and the first groove 1304 and the second groove 1305 at the same position are connected to form a slot hole 1301. The size of each first groove 1304 or each second groove 1305 can be the same or different, and is designed accordingly according to the size of the connector 20 of the dense bus duct. By providing the upper plate 1302 and the lower plate 1303, it is more convenient to place the bus duct during casting.

[0046] Figure 3 1 is a three-dimensional diagram of the end mold. The end mold 110 includes a first bottom plate 113 and two first side plates 114. The bottom end of the first side plate 114 is provided with a folding piece 1141, which is orthogonal to the first side plate 114. The folding piece 1141 is installed on the first bottom plate 113 by a fastener, so that the first side plate 114 is fixed to the first bottom plate 113. The first side plate 114 is bent into a Z shape to form a first end 1142 and a second end 1143. The first ends 1142 of the two first side plates 114 and the first bottom plate 113 enclose a first cavity 111, and the second ends 1143 of the two first side plates 114 and the first bottom plate 113 enclose a second cavity 112.

[0047] Figure 4 This is a three-dimensional image of the busbar mold. Figure 5The figure is a front view of the busbar mold. The busbar mold 120 includes a cover plate 121, a second bottom plate 122 and two second side plates 123. Removable connections are used between the cover plate 121 and the second side plates 123, and between the second bottom plate 122 and the second side plates 123. By adopting a removable connection, it is more convenient to dismantle the busbar mold 120. Specifically, the cover plate 121 is a U-shaped part with an opening downward. The bottom ends of both sides of the cover plate 121 are provided with a first flange 1211, and the top ends of the second side plates 123 are provided with a second flange 1231. The removable connection between the cover plate 121 and the second side plates 123 is realized by clamping the first flange 1211 and the second flange 1231. In this embodiment, the first flange 1211 is a triangular prism, and the inner surface of the side wall of the cover plate 121 extends a horizontal plane to the inside of the busbar mold 120, and the free end of the horizontal plane is connected to the side wall below to form an inclined plane, and the horizontal plane, the inclined plane and the side wall of the cover plate 121 form a triangular prism; the second flange 1231 is also a triangular prism, and the outer surface of the top of the second side plate 123 extends a horizontal plane to the outside of the busbar mold 120, and the free end of the horizontal plane is connected to the side plate wall above to form an inclined plane, and the horizontal plane, the inclined plane and the side plate wall also form a triangular prism. After the cover plate 121 and the second side plate 123 are clamped, the second flange 1231 is located above the first flange 1211. When closing the mold, place the cover plate 121 on the two second side plates 123, and then press the cover plate 121 down to make the cover plate 121 clamped on the second side plate 123. When demolding, the two ends of the cover plate 121 can be propped open to separate the cover plate 121 from the second side plate 123. The two ends of the second bottom plate 122 extend upward and bend toward the outside of the busbar mold 120 to form an extension arm 1221. Two positions adjacent to the inner wall at the bottom end of the second side plate 123 extend two upper and lower clamping edges 1232 into the inside of the busbar mold 120, and the two clamping edges 1232 form a sliding groove. When closing or demolding, the second bottom plate 122 is pushed into or out of the sliding groove along the longitudinal direction (i.e., the length direction) of the busbar mold 120 to achieve a detachable connection between the second bottom plate 122 and the second side plate 123. The busbar mold 120 can save mold installation time and improve casting efficiency by adopting a combined assembly structure.

[0048] In order to make the busbar 10 more stable during pouring, the pouring mold of this embodiment further includes an upper support member 140 and a lower support member 150 . Figure 6 is a three-dimensional diagram of the upper support member, Figure 7It is a three-dimensional diagram of the lower support member. The upper support member 140 and the lower support member 150 are both U-shaped members. The height of the second side wall 151 of the lower support member 150 is greater than the height of the first side wall 141 of the upper support member 140. The bottom end of the lower support member 150 is also provided with a boss 152, which is used to cooperate with the groove on the second bottom plate 122 of the busbar mold 120, so that the busbar is more stable. The upper support member 140 is used to snap on the upper end of the busbar 10, and the lower support member 150 is used to snap on the lower end of the busbar 10. The busbar 10 is pre-fixed by the upper support member 140 and the lower support member 150, and then poured.

[0049] During pouring, remove the cover plate 121 of the busbar mold 120, embed the busbar mold 120 into the first cavity 111 of the terminal mold 110, put the lower plate 1303 of the plug plate 130 into the second cavity 112 of the terminal mold 110, put the lower support 150 at both ends of the busbar mold 120, and then put the busbar 10 into the pouring mold and support it on the lower support 150, then buckle the support 140 on the busbar 10, and embed the upper plate 1302 of the plug plate 130 on the terminal mold 110 at both ends to complete the mold closing process before pouring. Then inject the pouring material (such as epoxy resin), and after the pouring material fills the pouring mold, cover the cover plate 121 of the busbar mold 120, and wait for the pouring material to completely solidify before removing the terminal mold 110. The busbar mold 120, as the outer shell of the bus duct, is not removed. In another example, after the casting material fills the casting mold, the cover plate 121 of the busbar mold 120 is not covered, and the end mold 110 and the busbar mold 120 can be removed after the casting material is completely solidified. Figure 8 shown.

[0050] In summary, by dividing the casting mold into two parts, namely the busbar mold 120 and the end head mold 110, the size of the busbar mold 120 is reduced, the casting material is saved when casting the busbar 10, and the volume of the dense bus duct after casting is small; the busbar mold 120 and the end head mold 110 are connected in an embedded manner, the top and two side ends of the end head mold 110 are open, and the cover plate 121 and the second bottom plate 122 of the busbar mold 120 are detachably connected to the second side plate 123, the disassembly and assembly efficiency is high, the production efficiency can be significantly improved, and the casting cost can be reduced.

[0051] The above embodiments are not exhaustive enumerations based on the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
