Injection pipeline system of composite material forming mold and injection method of injection pipeline system

The invention relates to an injection pipeline system for a composite material forming mold, which is characterized in that a vacuum source is communicated with a resin defoaming barrel through a defoaming device vacuum stop valve, and the defoaming device resin stop valve is arranged at an output port of the resin defoaming barrel; the gas pressure balance valve is arranged on the resin defoaming barrel, the output end of the resin defoaming barrel is communicated with the input end of the glue injection pipeline, the output end of the glue injection pipeline is used for being communicated with the input end of the forming mold, and the high-pressure gas source is communicated with the glue injection pipeline through a first connecting pipe. And a pressure electric proportional valve, a gas pressure stop valve and a pressure pipeline stop valve are arranged on the first connecting pipe. The injection pipeline system of the composite material forming mold aims at solving the problem of cleaning residual resin
