される。Prior art and its problems Immediately after the cast body of a lead-acid battery lattice body is cast by a casting machine, as shown in FIG. are doing. The useless bone portion 4 is an inner bone 6 at the lower end of the lattice body.
Since it is difficult for the molten metal to flow around the inner rib 6 and the inner rib 6 is not formed, that is, a cut occurs, this was necessary to prevent this. The sprue part 3 and the waste bone part 4 are A in the final stage of the casting process.
-A' and B-B' are cut and separated from the grid body 2.

性が増大するという欠点があつた。 The conventional method of cutting a cast body at the A-A' and B-B' sections is as shown in Fig. 2a (A-A' cutting section) and Fig. 2b (B-B' cutting section). Another method was to place the cast body 1 of the lattice body on the receiving teeth 8 of a cutting machine, and suspend the push teeth 9 from above for cutting. Therefore, as shown in FIG. 2c, a burr perpendicular to the plane of the lattice body 2 was generated at the cut portion in contact with the receiving tooth 8 side (lower right side in the figure). When electrode plates were manufactured using the grid and a storage battery was assembled, the burrs cut through the separator sandwiched between the positive and negative electrode plates, causing a short circuit between the positive and negative electrode plates. Therefore, in sealed lead-acid batteries in which the storage battery is self-discharged and the electrolyte is substantially impregnated into the positive and negative electrode plates and the separator, there have been cases where the battery explodes. Moreover, since the separator of a sealed lead-acid battery is made of fine fibers such as glass, the breakage of the separator due to the burrs becomes more pronounced, increasing the risk of self-discharge and explosion due to short circuit.
