Abstract

The invention discloses a double-cavity automatic cast welding mold and a lead supply system of the mold. The double-cavity automatic cast welding mold comprises two mold cavities, two manifolds, two lead inlets and a plurality of lead flow openings. The corresponding lead flow openings are formed in one side of the positive mold cavity, the positive manifold is arranged on one side of the lead flow openings, and the positive mold cavity, the lead flow openings and the positive manifold are internally communicated. The negative mold cavity, the corresponding lead flow openings and the negative manifold are arranged on one side of the positive mold cavity, the corresponding lead flow openings and the positive manifold in a mirror symmetry mode. Through the manifolds, a lead supply pipeline is divided into the two independent mold cavities, namely the positive mold cavity and the negative mold cavity, and two independent lead supply subsystems are formed. The positive manifold and the negative manifold supply lead separately, and therefore temperatures needed for smelting tabs of different thicknesses are better achieved; the speeds and flowing directions of molten lead entering the manifolds and the mold cavities are controlled, so that the temperatures of the molten lead in all portions of the manifolds and the mold cavities are consistent, and the purpose of improving the welding quality of storage batteries is achieved.

Description

technical field [0001] The invention belongs to the field of battery manufacturing, and in particular relates to a double-cavity automatic casting and welding mold and a lead supply system for the mold. Background technique [0002] At present, environmental protection requirements are increasingly demanding for battery manufacturers, and battery production is gradually developing from manual operations to automatic casting and welding. ~10%, the thicker positive tab requires more heat to melt than the negative tab. Moreover, the content of the positive and negative tab alloys is different. Generally, the tin content of the positive tab alloy is higher than that of the negative tab, and the composition and temperature of the lead liquid during casting welding are the same. If the temperature and alloy composition of this lead liquid are set according to the positive plate, it cannot meet Negative plate welding required quality requirements. On the contrary, if the temperat...
