Abstract

PURPOSE:To obtain a magnetic field orienting injection molding machine which requires no large consumption of power and can arrange the magnetizing axis easily and securely in a specified direction by laying a magnetic field generating means between the mounting plates and the molds in the injection molding machine. CONSTITUTION:The magnetic field generating means 6 and the yoke 4 are intervened between the molds 7, 8 and the mounting plates 1, 2. Therefore, as A shows, there is provided a magnetic field from one magnetic field generating means 6 to the molds 7, 8 through a mounting plate 2, a tie bar 3, an other mounting plate 1, magnetic field generating means 6, and in this magnetic field, magnetic field generating means 6, the mounting plate 2, the tie bar 3, the other mounting plate 1, the other magnetic field generating means 6, the molds 7, 8 form a closed magnetic path. The magnetic field is not attenuated by the clearance between magnetic field generating means (f) and the mounting plates (a), (c). Accordingly, since no clearance occurs in other than the sections to be molded, the consumption of power is low, the magnetic field due to both magnetic field generating means is changed easily into a repulsive magnetic field and radial orientation also can be executed.
