Abstract

PURPOSE: To manufacture molded pieces free from local strength lowering, large strain, distorsion, warp etc. by charging thermoplastic resin melt into a predetermined shape in a lower mold by using the robot in pressure-molding of thermoplastic resin melt.
CONSTITUTION: When thermoplastic resin melt which is plasticized by the extruder 1, stored in the accumulator 6 is charged on the inner face of the lower mold 12 via a flexible hose 18 and pressure-molded between an upper mold 11 and lower mold 12, means is used, which moves the nozzle 17 of the flexible hose 18 tip by the robot 16 according to the route stored in the computer through the preliminary molding trial and charges melt on the inner face of the lower mold 12. By this, molded pieces free from local strength lowering, large strain, distorsion, warp etc. can be manufactured.
