RTM Mold Structure for Rapid Impregnation of matrix resin

摘要

The RTM mold structure according to the present invention includes an upper mold 10; a plurality of gate units 20 disposed on the upper mold 10; The lower mold 30 coupled in the lower direction of the upper mold 10; sensor units 61 , 63 , 65 disposed on the lower mold 30 ; Injection discharging means 40 installed to penetrate the inside of the lower mold 30 in the vertical direction; and a suction unit 80 for smoothing the flow of the introduced resin by providing a suction force to the runner formed on the upper mold 10; 10,30) check whether the polyurethane (PU) resin flowing into the inside is filled and the pressure inside the mold (10,30), and after the filling of the introduced polyurethane (PU) resin is completed, the resin is cured and converted into a solid state to measure the change in the opening time of the molds 10 and 30 .
