摘要： An injection assembly for an injection molding machine includes a plasticizing screw defining an axis, a housing, and a drive train, which is accommodated in the housing, for moving the plasticizing screw in an axial direction and for turning the plasticizing screw. The drive train includes an injection drive having a screw mechanism with a threaded shaft moveable in direction of an injection stroke, with the plasticizing screw being rigidly connected to the threaded shaft, and a rotary drive having a drive element, with the plasticizing screw being connected to the drive element such that the plasticizing screw is able to turn with the drive element and able to move in axial direction. The drive train is movably supported independently from the rotary drive by a support structure which includes a radial bearing disposed in an area between a screw-proximal end of the threaded shaft and the plasticizing screw, and a linear guide securely fixed to the housing for guiding the drive train during movement in the axial direction.

摘要： A hybrid injection unit for an injection molding machine includes a plasticizing screw having a shaft and constructed for rotation and axial displacement. Operatively connected to the shaft is a first electric motor for rotating the plasticizing screw, and a second electric motor for axial displacement of the plasticizing screw. A cost-efficient construction of the second electric motor and reduced stress of the linkage between this electric motor and the shaft is realized by providing at least one piston and cylinder unit in fluid communication with a pressure source for support of the second electric motor in injection direction, and a traverse acted upon by one end of the piston and cylinder unit and rotatably supporting the shaft of the plasticizing shaft. The traverse acts upon the shaft between a force introduction point of the second electric motor into the shaft, on one hand, and the plasticizing screw, on the other hand.

摘要： An electromagnetic coaxial driving injection apparatus, having a linear motor for driving injection and a rotation motor for metering. The linear motor and the rotation motor of both the injection and metering motors and an injection screw are set on a common axis. A connecting device connects moving parts of the motors with the injection screw. Stationary parts of the motors are fastened on a frame and forward-backward moving unit, not moving during injection and metering. Due to the arrangement of the moving parts and the injection screw on a single axis, moving parts are lessened, and transmission losses are minimized. Since the number of structural parts is low, only the moving parts of the motors move during injection while the stationary parts thereof remain at rest, thus greatly reducing inertia. Furthermore, since the moving axis of the injection screw and the injection screw are linked, without being connected with stators or other structural parts, injection is performed with minimal friction, enhancing effectiveness of the apparatus. The main characteristic of the present invention is that, due to direct driving of injection without mechanical transmission, the effects of hysteresis and backlash are avoided. Furthermore, inertia and friction are reduced. The present invention increases the response and reappearance of the system.
摘要翻译：一种具有用于驱动注射的线性电动机和用于计量的旋转电动机的电磁同轴驱动注射装置。注射和计量电机的线性电动机和旋转电动机和注射螺钉都设置在公共轴上。连接装置将电动机的运动部件与注射螺杆连接起来。马达的固定部件固定在框架和前后移动单元上，在注射和计量期间不移动。由于移动部件和注射螺杆在单个轴上的布置，运动部件减少，传动损失最小化。由于结构部件的数量少，所以在注射期间只有马达的运动部件在其静止部分保持静止的状态下移动，从而大大降低了惯性。此外，由于注射螺杆和注射螺杆的移动轴线连接而不与定子或其他结构部件连接，所以以最小的摩擦进行注射，提高了装置的有效性。本发明的主要特征在于，由于直接驱动没有机械传动的注射，所以避免了滞后和反向间隙的影响。此外，减少惯性和摩擦。本发明增加了系统的响应和再现性。

摘要： An electro-mechanical drive apparatus uses a single motor and three one-way clutches to provide both injection and extruder functions in the injection unit of an injection molding machine. When engaged, the first one-way clutch couples the feed screw to the frame of the injection unit, the second clutch couples the drive motor to the feed screw, and the third clutch couples the drive motor to the ball screw mechanism. During rotation of the drive motor in a forward (injection) direction, (a) the third one-way clutch engages, rotating the ball screw mechanism which results in forward movement of the feed screw; (b) the second one-way clutch slips; and (c) the first one-way clutch engages to prevent rotation of the feed screw as it moves forward. When the drive motor is rotated in a reverse (extrusion) direction, (a) the second one-way clutch engages, rotating the feed screw, (b) the first one-way clutch slips, and (c) the third one-way clutch slips, allowing rotation of the ball screw mechanism commensurate with the rearward movement of the feed screw. Three versions of the drive apparatus, each having its own specific advantages, are disclosed: (I) a double shaft motor mounted adjacent separate drive couplings for extrusion (feed screw rotation) and injection (ball screw rotation--feed screw translation); (II) a single shaft motor connected by a mechanical coupling to a transmission that alternately drives the feed screw and ball screw; and (III) a hollow (or double) shaft motor axially aligned with the feed screw and ball screw mechanism, so that one rotor shaft is coupled to the feed screw and the shaft is coupled to the ball screw mechanism.

摘要： An object is to increase the mechanical efficiency of an injection molding machine, decrease the inertia, and decrease the axial length. The injection molding machine comprises a cylinder member; an injection member disposed within the cylinder member such that the injection member can advance and retract; an injection motor (82); and a transmission shaft which is connected to the injection member such that the transmission shaft can rotate relative to the injection member. The transmission shaft has a rotation transmission portion, to which rotation of the injection motor (82) is transmitted, as well as a motion conversion portion for converting rotational motion to linear motion. The injection motor (82) and the transmission shaft are disposed on the same axis, and the transmission shaft is advanced and retracted inside the rotor (92) of the injection motor (82). In this case, since rotation of the injection motor (82) is transmitted directly to the transmission shaft without intervention of a speed reduction mechanism, a pulley, and the like, mechanical efficiency can be improved, and inertia can be decreased. Further, the time required for changeover from the injection stage to the pressure holding stage is shortened. Since the transmission shaft is advanced and retracted inside the rotor (92) of the injection motor (82), the injection molding machine can be reduced in axial length.
