The application relates to the technical field of battery cover plates and discloses a battery cover plate assembling method, which comprises the following assembling method: 1) a surrounding wall is arranged on a top cover sheet; 2) a pole has an upper section, a lower section and an outer peripheral wall, the outer peripheral wall is wrapped with a plastic insert, the top cover sheet has an annular part; a sealing ring is placed; 3) a positioning plate is placed on the outer peripheral wall; 4) the pole is fixed relative to the top cover sheet; 5) an upper plastic part is formed through injection molding, the upper plastic part has an inner annular part, and the inner annular part is wrapped around the outer periphery of the upper section; 6) a lower plastic part is arranged, and the lower plastic part is fixed relative to the top cover sheet; in the process of forming the upper plastic part through injection molding on the top cover sheet, the inner annular part of the upper plastic part is wrapped around the outer periphery of the upper section and abuts against the positioning plate, so that the injection molding of the upper plastic part is facilitated; secondly, the insulation between the pole and the top cover sheet is increased, so that the pole can bear large current; in addition, the structure is simple, the sealing and insulation effects are enhanced, the performance is good, and the assembling process is greatly simplified.

The utility model discloses a kind of nail bin injection moulds, including upper die mechanism and lower die mechanism, upper die mechanism has upper die core, lower die mechanism has lower die core, first, second top plate, lower die core is equipped with insert assembly and can be cooperated with upper die core, insert assembly cooperation and define cavity, first top plate is equipped with multiple first thimble and multiple oblique ejector pins of corresponding cavity front and back side distribution, second top plate is equipped with multiple second thimble respectively in cavity left and right end, the upper portion of first, second thimble is all worn insert assembly and can all extend to cavity, oblique ejector pin is obliquely slidably inserted in lower die core and can extend to the side wall of cavity, first, second top plate can be moved together, so that first, second thimble collectively push long strip-shaped nail bin, oblique ejector pin is obliquely moved to separate from long strip-shaped nail bin, second top plate can be relative to first top plate, so that second thimble pushes long strip-shaped nail bin. The utility model is beneficial to the injection molding of long strip-shaped nail bin and guarantee demoulding quality.
