Technical Field
The utility model relates to a can cast joint multiple specification battery busbar's mould belongs to battery technical field.
Background
The large-capacity storage battery is a necessary power supply device of a large-sized vehicle, the large-capacity storage battery is shown in a figure 1, the large-capacity storage battery is a structural schematic diagram and mainly comprises an outer wall 4, a pole group 2 and a busbar 1, the inner part of the outer wall 4 is divided into a plurality of independent spaces (six 12V storage batteries) with the same size and shape, the pole group 2 and the busbar 1 are installed in each space and filled with electrolyte to form a single-cell battery, and the plurality of single-cell batteries are connected in series and then supply power to vehicle-mounted electric appliances. The capacity requirements of different large-sized vehicles for the storage batteries are different, and the thickness of the pole group (the distance between the reinforcing ribs 3 on the outer wall 4 and the transverse intermediate wall 5 in fig. 1 is the pole group thickness) of the storage batteries with different capacities is different, so that the length of the bus bar 1 for connecting the pole group 2 is also different. The bus bar is formed by cast welding of metal lead, and at present, two ways for manufacturers to cast weld bus bars with different specifications are available: firstly, a pair of maximum-model cast-weld molds are used for cast-welding the busbars of the storage batteries with different capacities, and although the molds do not need to be replaced in the mode, when the small-model busbars are cast-welded, redundant parts are arranged at the end parts of the busbars, so that the waste of lead materials is caused, and the manufacturing cost of products is increased; secondly, the bus bars with corresponding models are produced by using the cast-weld molds with different specifications, although the mode can not cause the waste of lead, the production cost of products can be increased by preparing the molds with various models, and the cast-weld molds need to be frequently replaced and debugged in the cast-weld process, so that the production efficiency is reduced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to the drawback of prior art, provide a battery busbar cast joint mould that the commonality is strong to reduce the manufacturing cost of busbar, and improve production efficiency.
The problem of the utility model is solved with following technical scheme:
the utility model provides a battery busbar cast joint mould that commonality is strong, includes mould base plate and slider in the constitution, the upper surface of mould base plate is equipped with the busbar phase-match of cross sectional shape and large capacity battery and length is greater than the busbar die cavity of busbar, the slider embedding busbar die cavity the tip and with the inner wall sliding contact in busbar die cavity be equipped with the locking bolt between slider and mould base plate.
According to the storage battery busbar cast-weld mold with high universality, the part, located outside the busbar mold cavity, of the sliding block is expanded into a flat plate attached to the upper surface of the mold substrate, long bolt holes formed in the length direction of the busbar mold cavity are formed in the flat plate, and the threaded parts of the locking bolts penetrate through the long bolt holes and then are screwed into the threaded holes in the mold substrate.
The storage battery busbar cast-weld mold with high universality is characterized in that the busbar mold cavity and the slide block are arranged in a plurality, and each busbar mold cavity and each slide block correspond to one busbar of a high-capacity storage battery.
The storage battery busbar cast-weld mold with high universality is characterized in that two long bolt holes are formed in each sliding block, and the two long bolt holes are symmetrically arranged on two sides of a busbar mold cavity.
The utility model discloses a change the size that busbar die cavity inner space was adjusted to the position of slider to change the length of cast joint busbar, improved the commonality of cast joint mould greatly. The cast-weld mould can be used for conveniently cast-welding the storage battery busbars with various specifications, thereby not only avoiding the waste of metal lead and reducing the manufacturing cost of the busbars, but also not needing to replace the mould when the busbars with different specifications are cast-welded, and further improving the working efficiency.
Drawings
The present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a schematic view of a large capacity secondary battery;
fig. 2 is a schematic structural diagram of the present invention;
FIG. 3 is a cross-sectional view A-A of FIG. 2;
fig. 4 is a sectional view B-B of fig. 2.
The reference numbers in the figures are: 1. busbar, 2, utmost point crowd, 3, strengthening rib, 4, outer wall, 5, horizontal mid-board, 6, mould base plate, 7, long bolt hole, 8, slider, 9, busbar die cavity, 10, locking bolt.
Detailed Description
Referring to fig. 1, the pole group 2 of the accumulator is attached to the transverse intermediate wall 5 on one side and to the reinforcing ribs 3 on the outer wall 4 on the other side, the length of the busbar 1 varying with the thickness of the pole group, while the other dimensions are unchanged.
Referring to fig. 2, 3 and 4, the present invention includes a mold base 6, a slide 8 and a locking bolt 10. Be equipped with a plurality of busbar die cavity 9 on the mould base plate 6, every busbar die cavity 9 corresponds a busbar 1 of large capacity battery, the tip of every busbar die cavity 9 is equipped with a slider 8, slider 8 can slide and can be fastened by locking bolt 10 along the length direction of busbar die cavity 9, the part that except slider 8 pours into fused lead in the busbar die cavity 9, lead forms the busbar after solidifying, therefore the length accessible of busbar 1 adjusts by changing the position of slider 8. The long bolt hole 7 is the slider adjustable range, which is determined by the pole group thickness of the maximum capacity and minimum capacity batteries.
Utilize the utility model discloses during the preparation busbar, at first through the length of the 9 inner spaces of slider accurate adjustment busbar die cavity, make it match with the thickness size of utmost point crowd. Then lead water is filled into the busbar die cavity 9, the busbars suitable for different plate group thicknesses can be produced, so that raw materials can be reasonably utilized, waste is avoided, and the production efficiency can be improved.
