Small sealed accumulator cast-weld die

Abstract

The invention discloses a small sealed accumulator cast-weld die which comprises a cooling water inlet pipe, a die installation rack, a double-cavity die, electric heating pipes and water drainage pipes. The double-cavity die is arranged in the die installation rack. The output end of the cooling water inlet pipe is arranged in the middle of the bottom of the double-cavity die. The water drainage pipes are arranged at the two ends of the bottom of the double-cavity die respectively. Symmetric cooling water channels are arranged in the double-cavity die. Heating holes which transversely penetrate through the double-cavity die are formed in the double-cavity die. The electric heating pipes are arranged in the heating holes. By the adoption of the mode, the small sealed accumulator cast-weld die is specially designed for lead spraying operation, redundant molten lead can be scraped away conveniently after lead spraying operation, cooling water directly flows into the die, the electric heating pipes are directly communicated with the interior of the die, the heating speed and the cooling speed are high, cast-weld operation and cooling operation can be conducted after the die is moved away from a lead pan, the lead explosion phenomenon is avoided, safety is high, multiple sets of dies can be connected in parallel, production efficiency is improved, and maintenance is convenient.

Description

technical field [0001] The invention relates to the field of mold design for automatic casting and welding equipment, in particular to a casting and welding mold for small-density accumulator batteries. Background technique [0002] At present, the method of storing lead in the mold of the battery casting welding machine is generally to directly invade the lead pot, heat the lead liquid to 410°, put the liquid lead in, and then cool it to 260° with cold water and then demould. The interface between the cooling pipe and the mold uses It is welded, and it is easy to produce cracks and cause water leakage during the frequent heating and cooling cycles. When water enters the lead pot, it will cause lead explosion, which poses a threat to the safety of the operator. In addition, a small amount of lead slag condenses in the mold In the casting and welding cavity, the quality of casting and welding is affected, and regular cleaning (sandblasting or ultrasonic) and frequent maintena...

[0002] At present, the method of storing lead in the mold of the battery casting welding machine is generally to directly invade the lead pot, heat the lead liquid to 410°, put the liquid lead in, and then cool it to 260° with cold water and then demould. The interface between the cooling pipe and the mold uses It is welded, and it is easy to produce cracks and cause water leakage during the frequent heating and cooling cycles. When water enters the lead pot, it will cause lead explosion, which poses a threat to the safety of the operator. In addition, a small amount of lead slag condenses in the mold In the casting and welding cavity, it affects the quality of casting and welding, requires regular cleaning (sandblasting or ultrasonic), frequent maintenance

[0003] In order to change the disadvantages brought by the traditional method of containing lead, a new method of pouring lead is created, that is, the method of pouring lead is used to directly flow the lead liquid to the surface of the mold, but the traditional casting and welding mold is not suitable, so the casting and welding mold is also used. needs further improvement
