Injection molding mold and method for adiabatic joint of solid rocket engine

According to the solid rocket engine heat insulation layer injection molding mold and method, the mold is designed in advance and a runner is reasonably arranged according to the shape of a heat insulation connector product. And the metal joint is pre-installed and fixed in the mold, and the metal joint and the position where the heat insulation layer is bonded are coated with an adhesive and aired. The whole mold is installed on an injection machine, and a glue inlet of the mold is tightly matched with a glue injection opening of the injection machine. The heat insulation layer material is prepared into a strip to be fed into a feeding port of an injection machine, and the strip is extruded, exhausted and plasticized to be in a dense viscous flow state. And under the pressure action of an injection machine, the viscous heat insulation layer sizing material enters a mold cavity through an injection runner until the mold cavity is filled with the viscous heat insulation layer sizing material, and the injection
