Abstract

The invention discloses a water gap plate for a battery case mold. The water gap plate comprises a base plate and a flow channel structure; and the flow channel structure comprises a main flow channel, a secondary flow channel and a shunting pipe. The water gap plate further comprises a flow limiting valve and a flow limiting valve slot; and the flow limiting valve, which comprises a fixed part and a flow limiting part, is arranged in the flow limiting valve slot, wherein the fixed part can move in the flow limiting valve slot and drive the flow limiting part to move so as to limit the flow of adhesive flowing in an adhesive inlet point. The invention also discloses a battery case mold. According to the water gap plate for the battery case mold, the flow limiting valve and the flow limiting valve slot are adopted, the flow limiting valve is arranged in the flow limiting valve slot and comprises the fixed part and the flow limiting part, the fixed part can move in the flow limiting valve slot and drive the flow limiting part to move, so as to limit the flow of the adhesive flowing in the adhesive inlet point; and the flow limiting valve is arranged on the flow channel structure, so that the flow of the adhesive can be controlled by adjusting the flow limiting valve, the pressure of each cavity can be effectively adjusted, and the total external force on an insert can be reduced, and as a result, the problem that the adhesive is departed from the ribs of a battery case can be solved.

Description

technical field [0001] The application relates to the field of storage battery production, in particular to a nozzle plate used for a battery case mold and a battery case mold. Background technique [0002] The battery case is one of the outer carriers of the battery and is generally made of plastic. The quality of the battery case has a direct or indirect impact on the quality of the battery, so the injection molding quality of the battery case is particularly important. [0003] The battery casings of most batteries have multiple cavities, and adjacent cavities are separated by relatively thin and deep plastic ribs. figure 1 It is a schematic diagram of an existing battery shell mold, including a panel 11, a nozzle push plate 12, a nozzle plate 13, a plate 14, a push plate 15, a fixing plate 16 and a bottom plate 17, and the glue injection hole 21 is arranged on the panel 11 and the nozzle push plate 12 and communicate with the channel structure 22. When the battery cas...
