Description

Technical Field

[0001] The utility model relates to the technical field of production of battery parts, in particular to an injection mold for a battery insulation pad. Background Art

[0002] Battery insulation pads are an auxiliary material used in battery assembly. Their main function is to prevent short circuits between the positive and negative poles of the battery. Battery insulation pads are usually made of materials with poor conductivity and good insulation, such as plastic, rubber, special paper, etc. Injection molds are used in the production process of battery insulation pads.

[0003] Since multiple insulating pads are formed at one time during production, and the mold has no heat preservation function, if the raw material cools down too quickly, it will easily lead to uneven flow, affecting the molding quality. It is also inconvenient to take out after molding. Forcibly pulling the insulating pad to remove it will easily cause damage to the insulating pad, making it unusable and causing waste.
