    • A threaded shaft (52) for operating toggle joint (44) is driven for rotation by a first servomotor (46). A bevel gear (56) is mounted on the threaded shaft (52) for rotation relative to the threaded shaft (52). The bevel gear (56) is driven for rotation by a second servomotor (57). Bevel gears (60) each having a threaded bore are supported on a rear plate (42) are engaged with threaded sections (40A) of tie bars (40), respectively. Power is transmitted from the bevel gear (56) through power transmitting mechanisms (61) to the bevel gears (60). Each power transmitting mechanism (61) comprises bevel gears (62, 63) engaged with the bevel gears (56, 60), respectively, and a clutch (64) interposed between the bevel gears (62, 63). The clutches (64) are engaged and disengaged selectively to adjust the parallelism of a movable mold (36) with respect to a stationary mold (32).
    • 用于操作肘节(44)的螺纹轴(52)由第一伺服电机(46)驱动旋转。 伞形齿轮(56)安装在螺纹轴(52)上以相对于螺纹轴(52)旋转。 锥齿轮(56)由第二伺服电机(57)驱动旋转。 分别在后板(42)上支撑有螺纹孔的锥齿轮(60)分别与连杆(40)的螺纹部分(40A)接合。 动力通过动力传递机构(61)从伞齿轮(56)传递到伞齿轮(60)。 每个动力传递机构(61)分别包括与锥齿轮(56,60)啮合的锥齿轮(62,63)和插入在锥齿轮(62,63)之间的离合器(64)。 离合器(64)被选择性地接合和分离以调节可动模具(36)相对于固定模具(32)的平行度。

    • An injection apparatus of an injection molding machine, for easy control of the charging motor and the injection motor and highly precise control of the back pressure of a screw thereby enabling performance of the proper charging operation, has an injection motor with a rotor adapted to act as a ball screw nut and which is secured to an injection carriage having mounted thereon a heating barrel of the injection apparatus. The injection motor has a shaft forming a ball screw in one end portion of the shaft connected to a screw of the injection molding machine. The ball screw is screwed into the rotor of the injection motor. The other end of the shaft forms a spline portion, and is connected to a charging motor that has a hollow drive shaft whose inside-diameter portion is spline-fitted onto the spline portion of the shaft.
