PROBLEM TO BE SOLVED: To provide a particle feeding device for expansion molding, from which an expandable resin particle can smoothly be fed to/packed in a cavity of a molding die by using the air from a blower without causing clogging and without imposing a large load on the blower.SOLUTION: A suction port 5c is arranged in a base end part 5a of a feed pipeline 5 for feeding the expandable resin particle to a cavity 2 of a molding die 1. A nozzle 7 is made to penetrate an end plate 5d of the base end part 5a and projected into the central part thereof. Air is fed forcibly to the nozzle 7 from a blower 6 to generate negative pressure, which is used for sucking the expandable resin particle into the base end part 5a, by using the air to be jetted from the nozzle 7 so that the expandable resin particle is fed to/packed in the cavity 2 through the feed pipeline 5 and a filling machine 3. |
