Problems solved by technology

In the casting process of lead parts, the traditional casting mold core does not deal with the air in the mold core cavity, and the cast lead parts contain a large number of pores, resulting in poor molding of lead parts and pores in lead parts, resulting in poor molding A lot of unnecessary waste, waste of a lot of raw materials and labor costs of workers, if the lead parts containing pores are used in the battery, during the use of the battery, these pores will accelerate the corrosion of the lead parts by the electrolyte, Affect the usage of the battery and reduce the service life of the battery

Abstract

The invention discloses a model comprising a first sub-model and a second sub-model, which are arranged symmetrically; the splicing surface of the first sub-model and the second sub-model divides a plurality of die cavities of the splicing model into two same parts; a plurality of exhaust holes are formed on the splicing surface of the first sub-model and the second sub-model; and the exhaust holes and the die cavities are arranged at intervals. Compared with the prior art, the model provided by the invention adopts a symmetrical structure to replace the original integral model, and the exhaust holes and exhaust slots are formed on the model, thus, under the condition of not affecting the casting quality, the exhaust capability in the die cavities can be enhanced during the casting process as much as possible, the poor shaping due to air during the casting process of lead parts and air hole phenomenon in the lead parts are further reduced, the casting quality of the lead parts of a lead-acid battery is improved and the quality of the lead-acid battery is also improved.

Description

technical field [0001] The invention belongs to the technical field of lead-acid batteries, in particular to a mold for casting lead parts of lead-acid batteries. Background technique [0002] As an environmentally friendly power source, lead-acid batteries are widely used in various fields due to their low price, reliable quality, large capacity range, easy maintenance, and long service life. [0003] The quality of the lead parts in the lead-acid battery directly affects the quality and service life of the lead-acid battery. In the casting process of lead parts, the traditional casting mold core does not deal with the air in the mold core cavity, and the cast lead parts contain a large number of pores, resulting in poor molding of lead parts and pores in lead parts, resulting in poor molding A lot of unnecessary waste, waste of a lot of raw materials and labor costs of workers, if the lead parts containing pores are used in the battery, during the use of the battery, thes...
