Plastic composite reinforced plate production mold

The invention discloses a plastic composite reinforced plate production mold which comprises a reinforcing layer damping device, a divergent mold, a confluence mold and an elastic mouth mold, the reinforcing layer damping device is installed at the inlet end of the divergent mold, the divergent mold and the confluence mold are connected to form a mold body, and the elastic mouth mold is installed at the outlet end of the confluence mold. A feeding hole of the divergent die is connected with a connector of a plastic extruder, so that molten plastic extruded by the plastic extruder enters the divergent die to be diverted into an upper layer and a lower layer, then enters the confluence die to be combined with a middle reinforcing layer, and is formed into a plate blank of the plastic composite reinforced plate through the elastic mouth die together. The invention can ensure that the reinforcing layer of the composite reinforced plate is tightly combined with the outer plastic and the reinforcing layer is center
