Abstract: A molding machine comprising an injection portion with an injection nozzle which injects a molding material, a turntable comprising a rotation driving apparatus, a plurality of molds placed along a peripheral edge of the turntable, an attaching and detaching station, an injection station and a plurality of curing stations. Each mold comprises a material receiving port communicating with the injection nozzle when the mold is positioned at the injection station. Each mold further comprises a mechanism which close the material receiving port so as to prevent the molding material from flowing backward when the mold is separated from the injection nozzle. The molds are transferred by rotation of the turntable to each station one by one. Primary formed products are attached to the molds at the attaching and detaching station, injected at the injection station, cured to be second formed products at the curing stations and finally took out at the attaching and detaching station.
