WIPO Patent Application WO/2020/184610

A1

[Problem] To provide a molding device, etc. with which an article of good quality can be easily and efficiently obtained by injection molding. [Solution] The present invention comprises: a metal mold 10 for injection molding that has a communication hole 140 which establishes communication between a cavity 100 and the outside; an injection device 70 that supplies a molding material in a molten state into the cavity 100; a microwave irradiation means 30; and a transmission means 20 for microwave transmission that is attached to the microwave irradiation means 30 at one end and to the metal mold 10 at another end so that microwaves are irradiated into the cavity 100 via the communication hole 140. A flow passage 110 for guiding the molding material supplied from the injection device 70 into the cavity 100 is formed, together with the cavity 100, in the metal die 10. The microwaves are irradiated into the cavity 100 such that the microwaves are strong in and near an opening part 130 through which the molding material is injected from the flow passage 110 into the cavity 100.
