PURPOSE:To provide a foam molding raw material filling machine capable of efficiently filling a mold with a raw material by preventing the generation of the clogging of the gap between a piston and the inner wall of a raw material supply pipe with the raw material and reduced in the stroke of a cylinder. CONSTITUTION:In a foam molding raw material filling machine wherein a piston 4 opening and closing the opening part 2 for filling a foaming mold with a pre-foamed granular raw material by the operation of a cylinder is provided to the rear of a raw material supply pipe 1 having the opening part 2 provided to the leading end thereof, a nozzle pipe 15 which becomes smaller in its inner diameter toward the leading end thereof and injects air for supplying the raw material toward the gap between the piston 4 and the raw material supply pipe 1 from the rear position of the piston at the time of the return movement of the piston 4 is provided in the raw material supply pipe 1. |
