Abstract

The utility model relates to a burning-in mold for the pole group of a battery. The burning-in mold comprises a burning-in mold body, positive strap burning-in chambers and negative strap burning-in chambers. The burning-in mold is characterized in that a bridge burning-in chamber is respectively arranged on the burning-in mold body between one positive strap burning-in chamber and one negative strap burning-in chamber which need to be communicated with each other; a through hole is respectively formed on the burning-in mold body above each bridge burning-in chamber; a corresponding loose core is respectively arranged in each through hole; each loose core comprises a cone-shaped body and a locating block arranged on the cone-shaped body; and the taper of each cone-shaped body ranges from 1:30 to 1:50. The burning-in mold has the advantage in improving the production efficiency of the battery.

Description

A kind of accumulator pole group cast welded mold

One, technical field

The utility model relates to a kind of cast welded mold, relates in particular to a kind of lead acid accumulator pole group cast welded mold.

Two, background technology

There are a plurality of cells that work independently lead-acid accumulator inside at present, these cell structures are identical, positive plate and negative plate have all been comprised, the factor amount is more, it adopts cast welded mold to weld identical pole plate is connected, this cast welded mold comprises a cast welding die body, is provided with battery bus-bar cast welding chamber on the cast welding die body; By this mould at same row's the identical pole plate direct casting bus-bar of burn-oning, the identical pole plate of this row is connected, but still need to connect by artificial welding between the bus-bar that connects positive plate and the bus-bar that is connected negative plate, its production efficiency can't be further improved.

Three, summary of the invention

At above-mentioned shortcoming, the purpose of this utility model is to provide a kind of accumulator pole group cast welded mold, its bus-bar that can make internal storage battery connect positive plate directly connects by a cast welding with the bus-bar that is connected negative plate, thereby improves the production efficiency of battery.

Technology contents of the present utility model is that a kind of accumulator pole group cast welded mold comprises the cast welding die body, is provided with positive bus cast welding chamber and negative bus-bar cast welding chamber on the cast welding die body; It is characterized by on positive bus that need are communicated with and the cast welding die body between the negative bus-bar and be provided with a gap bridge cast welding chamber, on the cast welding die body above the gap bridge cast welding chamber, be provided with the bar jack of loosing core, in the bar jack of loosing core, be provided with the bar of loosing core of a correspondence, the bar of loosing core comprises a cone and locating piece, locating piece is located on the cone, and the tapering of cone is 1: 30～1: 50.

The advantage that the utility model compared with prior art has is: passing a bridge in cast welding simultaneously between positive bus and the negative bus-bar when the cast welding pole plate bus-bar by cast welded mold makes positive bus be communicated with negative bus-bar, save the time of artificial welding, thereby improved the production efficiency of battery.
