摘要： PROBLEM TO BE SOLVED: To provide a molding method, with which molding can be realized without being influenced by the mechanical difference between two cylinders, when the amount of injection by once can be sufficed by one cylinder in a molding method, in which a double head type injection molder is employed. SOLUTION: A pair of cylinders 10 and 11 for plasticizing and injecting resin are respectively communicated with guide holes 28a and 28b on respective head sides. The guide holes 28a and 28b meet through shut-off valves 30 and 31 so as to communicate to an injection nozzle 4. The molding action employing one of cylinders 10 and 11 and the molding action employing the other one of the cylinders are performed alternately. While plasticizing action is performed also by one cylinder in parallel with the molding action of the other cylinder with each other.

摘要： PURPOSE: To make the volume of a mold clamping cylinder smaller than ever are realize the shortening of pressure rise timing by a method wherein a hydraulic cylinder is so controlled as to stop a travelling die plate at its expected position on the basis of a detecting means under the condition that half nuts provided on the surface in the opposite side of the mold mounting surface of a travelling die plate are engaged with the threaded part at the tip of each tie bar. CONSTITUTION: Each tie bar 15 is directly connected to one side surface of each mold clamping ram 13 and held through each inserting hole 27 of a travelling die plate 9, which faces opposite to the tie bar 15. To a fixed die plate 5, each travelling cylinder 17 is fixed. Pairs of half nuts 29 engaging with the threaded part of the tie bar 15 are provided so as to pinch each axis center of the inserting hole 27. During the movement of the travelling die plate 9, the counter of a controlling device records the number of divisions detected with a position sensor 41 so as to issue a command to stop the travelling cylinder 17 when the recorded number of divisions reaches the stored number of divisions. At this instant, the half nuts 29 are engaged with the thread of the tie bar 15. After that, pressure oil is fed to the hydraulic cylinder 13 so as to clamp the molds.
