PURPOSE:To produce a large-sized complicate molded article correctly and efficiently by flow molding the fluid plastic resin while moving a nozzle about a mold in accordance with a preset program. CONSTITUTION:After supplying the resin into a thermally melting mechanism 10 comprised of an extruder or a liquid pump and mixing and dispersing the resin, the fluid resin is fed into a measuring mechanism 30 through a supplying mechanism 20 consisting of a flexible connecting pipe and an amount of the resin corresponding to one batch is measured and reserved. Then, the resin is fed under pressure into an injecting mechanism 40 and is injected into the mold 71 whie moving the nozzle 43 by a moving mechanism 50. The movement of the nozzle 43 is performed by presetting a desired movement locus of the nozzle 43 on a movement-controlling mechanism 80 and moving the nozzle 43 within a nozzle moving range A together with the injecting mechanism 40 and the measuring mechanism 30 by the moving mechanism 50 in accordance with the programmed commands. |
