To provide a device for manufacturing a resin foam and a method for manufacturing the resin foam each capable of manufacturing the resin foam of a high foaming ratio with high shape precision.
The screw 20 contains a compression part 31 and the first to third supply parts 30a to 30c. A pitch of a flight 25 in the first supply part 30a is larger than the pitch of the flight 25 in the compression part 31. The pitch of the flight 25 in the second supply part 30b is smaller than the pitches of the flight 25 in the first and third supply parts 30a and 30c. An ultrasound impression mechanism 46 impresses ultrasound to a forming mold 40 for at least a part of the period from an initiation of resin injection into a cavity 43 by an injection mechanism 10 to completion of resin injection.
