RTM MOLD STRUCTURE FOR RAPID IMPREGNATION OF MATRIX RESIN

摘要

An RTM mold structure according to the present invention comprises: an upper mold (10); a plurality of gate units (20) disposed on the upper mold (10); a lower mold (30) which joins to the upper mold (10) in the downward direction of the upper mold (10); sensor units (61,63,65) disposed on the lower mold (30); an injected material discharge means (40) which is installed so as to vertically pass through the inside of the lower mold (30); and a suction unit (80) which supplies a suction power to a runner formed on the upper mold (10) and thereby facilitates movement of a resin introduced therein, wherein the sensor units (61,63,65) are used to check the filling status of polyurethane (PU) resin introduced into the molds (10, 30) and the internal pressure of the molds (10, 30) and to measure an opening time of the molds (10, 30) by checking if the resin is cured and solidified upon completion of the filling of the PU resin.;COPYRIGHT KIPO 2017
