Abstract

The utility model discloses an improved structure of a battery cast welding mould, which comprises a cast welding mould body, wherein the surface of the cast welding mould body is sequentially distributed with a plurality of forming structures used for casting headers; each forming structure consists of a positive pole concave channel slot and a negative pole concave channel slot; the positions of the positive pole concave channel slot and the negative pole concave channel slot in adjacent forming structures are arranged in a staggered manner, the positive pole concave channel slot or the negative pole concave channel slot in one of the forming structures corresponds to the positive pole concave channel slot or the negative pole concave channel slot in the adjacent forming structure to be connected into an integrated structure, so that structure of the cast welding mould surface is greatly simplified, the cast welding procedures are reduced, the welding efficiency is improved, the production cost is saved to a greatest extent while the welding quality is ensured.

Description

Improved structure of battery cast welded mold

Technical field

The utility model relates to a kind of cast welded mold, refers to be used for the cast welded mold that the lead-acid accumulator afflux is lined up type especially.

Background technology

It is to adopt the mode of welding to finish that polar plate of lead acid storage battery connects technology, but a plurality of cells that work independently are arranged in internal storage battery, these cell structures are identical, all comprised positive plate and negative plate, the factor amount is more, adopts the words of artificial welding fully, required labour is big, production efficiency is very low, but the welding quality of battery is not high, therefore needs a kind of special cast welded mold to carry out welding job.As shown in Figure 1, have the concave path groove 01 that battery current collecting is lined up type on the known battery cast welded mould at present, concave path groove 01 is parallel distribution up and down, after battery pole ear inserts concave path groove, forms negative afflux row and positive afflux row.The concave path groove of each battery cell correspondence is independently to separate, also need pole groove 02 to be set and be used to two the adjacent battery cells that are connected in series in the concave path groove end, therefore after each afflux is lined up the type operation, also need to carry out monomer and connect operation, pole is connected as one, the increase of this procedure causes battery production cycle lengthening, and production efficiency reduces; Being provided with of pole groove increased the cast welding consumption of lead, causes the internal resistance of cell to increase, and product quality but can not get guaranteeing when production cost improved.In order to adapt to full-automatic production, save cost to greatest extent, guarantee the welding quality of battery pole piece, just need improve once again, to obtain best result of use existing cast welded mold.

Summary of the invention

Problem to be solved in the utility model is exactly the shortcoming at prior art, and a kind of improved structure of battery cast welded mold is provided, and has greatly simplified the structure on cast welded mold surface, reduce the cast welding operation, improve welding efficiency, when guaranteeing welding quality, save production cost to greatest extent.

For reaching above-mentioned purpose, the utility model adopts following technical scheme: improved structure of battery cast welded mold, comprise the cast-weldmould body, distribute successively several afflux rows' that are used to cast molding structure of cast-weldmould body surface, each molding structure is made up of anodal concave path groove and negative pole concave path groove, the anodal concave path groove in the adjacent molding structure and the position of negative pole concave path groove are crisscross arranged, and it is characterized in that: negative pole concave path groove in one of them molding structure or anodal concave path groove anodal concave path groove or negative pole concave path groove corresponding and that adjacent molding structure is interior connect as one structure.

Advantage of the present utility model:

At utmost save consumption of lead, reduce the internal resistance of cell, the utility model has been removed the pole groove in original cast-weldmould, has so just saved the plumbous amount of part between battery electrode column, pole and the afflux row, and inside battery is at utmost saved consumption of lead;

Increase the battery volume and capacity ratio, because one of them concave path groove in the adjacent molding structure connects as one each other, afflux is arranged original orientation and is enhanced battery case oral thermometer face, and the original pole plate height of battery can design higher, so the capacity of battery also can design higher;

Saving next process operation is enhanced productivity, owing to removed the pole groove in original cast-weldmould, and concave path groove connects as one structure each other, removed monomer from and connected operation, saves time, laborsaving, material saving.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the structural representation on cast welded mold surface in the prior art;

Fig. 2 is the structural representation of the utility model cast-weldmould body surface.

The specific embodiment

As shown in Figure 2, the utility model is an improved structure of battery cast welded mold, comprise cast-weldmould body 1, distribute successively several afflux rows' that are used to cast molding structure 2 of cast-weldmould body 1 surface, each molding structure 2 is made up of with negative pole concave path groove 21 anodal concave path groove 22, anodal concave path groove 22 in the adjacent molding structure 2 is crisscross arranged with the position of negative pole concave path groove 21, and anodal concave path groove 22 or negative pole concave path groove 21 in negative pole concave path groove 21 in one of them molding structure 2 or anodal the concave path groove 22 corresponding and adjacent molding structures 2 connect as one structure.As shown in Figure 2, the setting of anodal concave path groove and negative pole concave path groove is only for more clearly illustrating the molding structure of the utility model cast-weldmould, embodiment of the present utility model is limited, direction is seen from left to right, negative pole concave path groove 21 in first molding structure 2 and second molding structure 2 interior anodal concave path groove 22 one are connected, and the like, form stepped syndeton, connect operation thereby saved monomer, save time, laborsaving, material saving.
