Abstract of the Disclosure The invention relates to a method of detecting the filling weight for an injection molder, or specifically to a method of detecting the weight of the plasticized synthetic resin injected from the injection molder cylinder to fill in the cavity of a mold. The objective is to ensure highly accurate detection of the filling weight, on the injection molder side, in continuous molding production. According to the invention, the weight of the resin injected from the cylinder to fill in the cavity is detected through opera- tions on the basis of the positional values of the screw and the pressure and temperature values of the resin obtained before and after injection with the resin pressure main- tained at a specified value and with the block valve and check valve closed. - 32 -
