Automotive busbar accessories injection molds are used to injection - mold fixtures onto the busbar's copper bar set. Its structure generally consists of an upper mold and a lower mold:
Upper mold: It is equipped with multiple glue - pouring holes that are connected to the injection - molding cavity, allowing fluid - like plastic to flow in. It also has several holes for accommodating the welding pins of the copper bar set. After the copper bar set is fixed to the upper mold, the star - point copper bar is located between the U - phase, V - phase, and W - phase copper wires and the upper mold.
Lower mold: It forms multiple independent injection - molding cavities with the upper mold for molding split - type fixtures.
In addition, to solve the heat - dissipation problem, some automotive busbar accessories injection molds are also equipped with heat - dissipation structures. For example, they use a C - shaped heat - dissipation tube, and the coolant circulates to take away heat, ensuring the stability and safety of the mold and the product.
