Abstract:
There are provided a powder slush molding machine that preheats a mold using the transfer time of the mold and may be reduced in size, and a powder slush molding method using the powder slush molding machine.
There are provided a powder slush molding machine and a powder slush molding method using the powder slush molding machine. The powder slush molding machine includes: a mold heating portion that heats a mold so that the temperature of the mold is set to a value equal to or higher than a predetermined temperature; a powder slush portion that sprays a molding resin, while powdering the molding resin, to mold a sheet-like material having a predetermined thickness on the inner surface of the heated mold; a mold cooling portion that cools the mold so that the temperature of the mold is equal to or lower than a predetermined temperature; a mold working portion that separates the cooled sheet-like material from the mold; and a transport device that moves the mold between the respective portions. A preheating device for heating the mold is provided at a part of the transport device.
