Description

Casting and welding molds for the manufacture of lead-acid batteries

technical field

The invention relates to a casting and welding mold for manufacturing lead-acid batteries.

Background technique

Existing lead-acid batteries usually have an electrode group consisting of several positive plates and several negative plates, and the positive tabs and negative tabs in the pole group are respectively connected through a bus plate. At present, the soldering of lead-acid battery pole groups mainly adopts manual busbar welding; Manifold. In this way, it is not only difficult to remove the bus plate after soldering, but also the positive and negative pole heads on the bus bar after demoulding need to be manually welded to form a bridge. This method is labor-intensive and time-consuming, has low efficacy, and causes unreliable quality due to artificial factors, and the operation environment pollutes a lot, which is not conducive to environmental protection, but also harmful to the health of operators.

Contents of the invention

The object of the present invention is to provide a kind of cast-welding method for manufacturing lead-acid batteries which is easy to demould, low in mold cost, small in amount of lead raw material, and can be in a weldable vertical state at the cross-bridge post at the top of the busbar after demoulding. Mold Casting Welding Mold Casting Welding Mold.

The purpose of the present invention is achieved through the following technical solutions: it is characterized in that two rows of bus bar grooves are provided on the front of the mold, and one row of bus bar grooves consists of several transverse grooves, several column head grooves, several The other row of busbar grooves consists of several transverse grooves, several column head grooves, several bridge grooves, and a positive lug groove and a negative lug groove respectively located at the left and right ends. Groove; the column head groove is a vertical groove, and the bridge groove is an arc groove, which is composed of two column head grooves and one of the bridge grooves on both sides of the bridge groove. The bridge grooves are connected to form a "U"-shaped groove; the two column head grooves in one of the "U"-shaped grooves are respectively connected with one of the transverse grooves to form a bus groove Each row of bus bar grooves is composed of several bus bar groove units, and each bus bar groove unit is isolated from each other; the positive lug groove and the negative lug groove are respectively connected with a transverse groove.

Compared with the prior art, the present invention has the advantages of reducing the procedure of manual welding to cross the bridge, thereby avoiding the human body damage caused by lead fumes during the manual welding process of workers and reducing environmental pollution. Due to the one-time flux molding of the mold, the quality instability caused by manual welding is overcome, so the product quality is improved; and the mold can also become thinner, and the mold cost becomes more economical.

Detailed ways

The content of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments of the description:

As shown in Figures 1 and 2, the mold of the present invention is characterized in that two rows of busbar grooves 1 are arranged on the front of the mold, wherein the busbar grooves of the first row are composed of several transverse grooves 2, several column heads The groove 3 and several bridge grooves 4 are formed. The second row of busbar grooves consists of several transverse grooves 2, several column head grooves 3, several bridge grooves 4 and one at the left and right ends respectively. The positive lug groove 5 and a negative lug groove 6 are formed; the stud groove 3 is a vertical groove, and the bridge groove 4 is an arc groove, which is respectively located on both sides of the bridge groove. The two column head grooves 3 are connected with one of the bridge grooves to form a "U" shaped groove; the two column head grooves in one of the "U" shaped grooves are respectively connected with the One of the transverse grooves is connected to form a bus bar groove unit, and each row of bus bar grooves is composed of several bus bar groove units. In Fig. 1 of this embodiment, the bus bar grooves of the first row There are three bus bar groove units in the groove, and two bus bar groove units are provided in the second row of bus bar groove units, and each bus bar groove unit is isolated from each other so as not to communicate with other groove units An independent groove unit; the positive lug groove 5 and the negative lug groove 6 communicate with a transverse groove 2 respectively, and their grooves are also independent.

In order to be able to erect the post and the bridge of the lead-acid battery during the demoulding process, in the busbar groove unit, the part located in the bridge groove, the side wall of the groove and the groove The intersection of the bottom surface is close to a right angle or a right angle, without chamfering; while the grooves in other parts are all provided with chamfering. In order to facilitate the demoulding, the groove part of the bridge is the most difficult to demould and the demoulding is the last, and it is demoulded under the action of a certain demoulding force. Finally, the column caps and bridges in a vertical state are formed.

In the groove unit of the bus bar, the depths of the grooves are all equal. Therefore, the thickness of the mold of the present invention is thinner than the original mold.

The grooves of the first row and the second row of busbars are dislocated and distributed symmetrically.
