Embodiment

[0023] This embodiment describes a general flexible lamination mold for making laminated busbars. The laminated busbar 1 in this embodiment consists of an outer insulating film 5 , an intermediate insulating film 6 and a copper plate 4 . The structure of the laminated busbar 1 when it is not pressed and closed is as follows figure 2 As shown, the edge is not closed; the edge of the laminated busbar 1 is closed after pressing and sealing, that is, the outer edge and inner hole edge of the laminated busbar 1 are closed, and its structure is as follows image 3 shown.

[0024] The universal flexible press die such as Figure 4 As shown, it includes two parts, the upper mold 2 and the lower mold 3. The busbar 1 to be pressed is placed between the upper mold 2 and the lower mold 3. The upper mold 2 includes an upper mold cavity 7 and the The silicone grease 8 , the lower mold 3 includes a lower mold cavity 9 and silicone grease 10 filled in the lower mold cavity 9 . Among them,...

Abstract

The invention discloses a universal flexible pressing mould for manufacturing a laminated busbar. The universal flexible pressing mould comprises an upper die and a lower die, a busbar to be pressed is arranged between the upper die and the lower die, the upper die comprises an upper die cavity and silicone grease filled in the upper die cavity, and the lower die comprises a lower die cavity and silicone grease filled in the lower die cavity. According to the universal flexible pressing mould for manufacturing the laminated busbar, which is disclosed by the invention, the silicone grease respectively filled in the upper die cavity and the lower die cavity is used for conducting the heat and transferring the pressure and can flexibly form matched concave/convex die structures according to different busbars under the pressure, so that the laminated busbar is pressed and the edge of the laminated busbar is sealed. Therefore, the universal flexible pressing mould disclosed by the invention can meet the pressing requirements of different-structure busbars and has the universality; the upper die cavity and the lower die cavity are filled with the silicone grease so as to have a good pressed flexible formation function and a good heat transfer function; the research, development and trial-manufacture costs of the busbar are reduced, and the machining period is shortened; and the mould is simply and conveniently manufactured and maintained.

Description

technical field [0001] The invention relates to the technical field of laminated busbar production, in particular to a general flexible pressing mold used for lamination during the production of laminated busbars. Background technique [0002] Laminated busbar, also known as composite busbar, low-inductance busbar, is a multi-layer composite structure connection bar. The edge-closed laminated busbar with insulating film is a common structure of laminated busbar, which is composed of multi-layer copper plate (or aluminum plate), high temperature and high voltage resistant insulating film. Heat-melt and press-bond the edge of the busbar through special hot-melt pressing equipment and busbar pressing mold, that is, use the outer insulating film and the interlayer insulating film of the copper bar to seal the edge of the copper plate to ensure insulation and voltage resistance. [0003] Existing busbar pressing molds are usually made of aluminum plates, such as figure 1 As sho...
