Embodiment Construction
[0016] A method for one-time injection molding of a bipolar plate sealing assembly according to the present invention, the method includes the following steps:
[0017] (1) Sealing grooves and glue injection holes connected to the sealing grooves on both sides are provided on both sides of the bipolar plate body, and an exhaust port is reserved on the sealing grooves; the sealing groove is to solidify the sealing material in the groove and form The fixed shape meets the sealing requirements, and the exhaust port is to discharge the original air in the groove in time when the sealing material is injected into the groove, which is not only conducive to the flow of the glue injection material, but also prevents residual influence in the cured sealing component. Airtight quality air bubbles;
[0018] (2) prepare a pair of mold according to the shape of bipolar plate, this mold has sealing ring mold cavity and glue injection opening corresponding to the sealing groove on the bipola...
