摘要： An object is to reduce the axial dimension of an injection apparatus (31), facilitate the work of removing and inserting a screw (20), and improve the quality of molded products. The injection apparatus (31) comprises a heating cylinder (17), a screw (20), and a drive apparatus. The screw (20) includes a plasticizing portion which includes a body portion (45a) and a flight (53) projectingly formed on an outer circumferential surface of the body portion (45a). An index ε, which is obtained by dividing a value obtained by adding a screw stroke S and a screw effective length L together by the screw stroke S, satisfies the relation 2.0

摘要： The extruder screw drive has a first and a second motor, a screw mechanism connected to the first motor and to the extruder screw for translating it in the extrusion cylinder, and a slide mechanism connected to the second motor and to the extruder screw for rotating it in the extrusion cylinder. The screw mechanism and the slide mechanism are coaxial and partially fit into one another to provide an axially compact arrangement. The motors can be hollow shaft electric motors axially aligned together, and pressure regulated hydraulic axial force can be added to the extruder screw during plasticating as it retracts due to increased volume of plastic at an output end of the extrusion cylinder.

摘要： What is disclosed is an injection unit for an injection molding machine, comprising a screw which may be driven by means of a spindle drive. Driving of the spindle drive is effected by means of an electric motor. In addition, through the intermediary of a hydraulic cylinder a force acting in the axial direction is transmitted to the screw of the injection unit. In accordance with the invention, the electric motor drives a pump whereby a pressure chamber of the cylinder may be supplied with more pressure medium than is required in an axial displacement of the cylinder.

摘要： An injection unit for injection molding machines includes an extruder as plasticizing unit and a plunger-type injection molding device that can be coupled to the injection molding machine by an injection nozzle. The plunger-type injection molding machine has an injection plunger, wherein the area in front of the injection plunger forms an injection space which is connected to a forward end of the extruder by a melt channel, with a shutoff valve disposed in the melt channel. The extruder can be continuously operated and has one or more plasticizing screws for plastification, wherein the extruder is so configured that a backup length is able to increase backwards into the extruder, when the shutoff valve is closed.

摘要： An injection unit for a plastic injection molding machine having a screw, having a motion spindle as first drive element, via which the screw can be rotationally driven for the plasticization and is movable in the axial direction for the injection, having a spindle nut as second drive element, which is coupled to the motion spindle via a motion screw thread, having a large electric motor which is arranged so as to be fixed to the frame and by which, while one drive element is held against rotation, the other drive element can be rotationally driven for moving the screw during the injection, and having a device which is arranged so as to be fixed to the frame and by which a rotational speed of the one drive element can be preset during the plasticization, this rotational speed being different from the rotational speed at which the large electric motor simultaneously drives the other drive element. In a known injection unit of this type, two equally large electric motors, which can both apply a large torque, are used, by which such a counter-torque is exerted on the motion spindle during the injection operation that the motion spindle does not rotate. On the whole, the known injection unit is quite expensive on account of the two electric motors designed for a high torque. In order to provide a more cost-effective injection unit, the drive element held against rotation during the moving of the screw for the injection can be locked by a releasable mechanical brake.
摘要翻译：一种用于塑料注射成型机的注塑单元，其具有螺杆，其具有作为第一驱动元件的运动主轴，螺杆可以被旋转驱动以进行塑化，并且可以在轴向方向上移动以进行注射，具有主轴螺母作为第二驱动元件驱动元件，其经由运动螺纹联接到运动心轴，具有大电动机，其被布置成固定到框架，并且当一个驱动元件被保持抵抗旋转时，另一个驱动元件可以在喷射期间被旋转地驱动以移动螺杆，并且具有被布置成固定到框架的装置，并且在塑化期间可以预设一个驱动元件的转速，该转速不同于大电动机同时驱动另一个驱动元件的转速。在这种类型的已知的注射单元中，使用两个同时施加大扭矩的同等大的电动机，在注射操作期间这样的反扭矩被施加在运动心轴上，使运动心轴不旋转。总体而言，已知的注射单元由于设计用于高扭矩的两个电动马达而相当昂贵。为了提供更具成本效益的注射单元，在用于注射的螺杆的移动期间保持抵抗旋转的驱动元件可以通过可释放的机械制动器来锁定。

摘要： An injection unit in which an offset load is not applied to a ball screw for moving an injection screw. A pusher plate is provided that is moved while being guided by guide rods extending between front and rear plates, and is mounted with the injection screw and the ball screw so as to be rotatable but axially immovable. The ball screw is threadedly engaged with a nut mounted to the rear plate so as to be unrotatable and axially immovable. A support plate is coupled through coupling rods to the pusher plate. The ball screw has another end supported on the support plate in a rotatable but axially immovable manner. The pusher and support plates are supported on a base by linear motion guides. The ball screw is supported at its both ends by the pusher and support plates so as not to be tilted, whereby no offset load is produced and the service life is prolonged.

摘要： An injection molding machine having an injection plunger (21) capable of moving back and forth within an injection chamber (22) includes a scraper ring (23) attached to one end of an injection cylinder (2) having a hole penetrated by the injection plunger. A protuberance (23a), which forms the smallest diameter portion of the hole penetrating the scraper ring and extends to the surface of the injection plunger, is formed on the inside wall of that scraper ring. The perimeters (23e, 23h) of this protuberance scrape off any molding material which adheres to the injection plunger. The scraper ring has windows (23f, 23g) for the purpose of dropping scraped-off material outside thereof. Preferably, the injection plunger has a shank (21b) and a head (21a) which forms the tip of the injection plunger and which has a diameter larger than the shank and slightly smaller than the injection chamber; the protuberance of the scraper ring has a diameter which is slightly larger than the shank and smaller than the head.
