Abstract

The invention discloses a die for preparation of a lead-acid battery holder. The die comprises a die plate, an injection tube is mounted in the top center of the template, six cylinders are symmetrically mounted on the top wall of the die plate, every three cylinders are positioned in a row and arranged at equal internal, and a channel is arranged in the die plate. According to the die, differentstructures are arranged so that a raw material can be discharged evenly and equivalently, the wall thickness of a prepared product is uniform, the quality is higher, and the raw material discharging speed can be adjusted.

Description

technical field [0001] The invention relates to the technical field of lead-acid battery boxes, in particular to a mold for preparing lead-acid battery boxes. Background technique [0002] A lead-acid battery is a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. In the discharge state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charging state, the main component of the positive and negative electrodes is lead sulfate. [0003] The battery box of the lead-acid battery is prepared using a casting mold. The existing casting mold for the lead-acid battery box has the following disadvantages: when pouring, the raw material is not uniformly discharged, and the discharging speed of the raw material is uncontrollable, resulting in uneven wall thickness of the battery box. Even, the product defective rate is hig...
