摘要： An injection molding device includes a continuously operating extruder and a discontinuously operating injection unit receiving plastic material from the extruder. The extruder has an extruder barrel which includes a plasticizing zone and a discharge zone, whereby the discharge zone is configured to provide an intermediate storage space and has a cross sectional area which is greater than a cross sectional area of the plasticizing zone. In this way, the discharge zone provides a buffer volume which is filled during the injection process and then emptied again.

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： A mould closing device for an injection moulding machine includes a fixed (1) and a movable (4) mould clamping plate for support of screw drives (36) which are freely rotatable in the fixed mould clamping plate (1) and axially supported in one direction and supported in spindle nuts (39) secured in the movable mould clamping plate (4). Provided for actuation of the screw drives (36) for the closing and opening stroke of the movable mould clamping plate (4) are a rotary drive (44) and a hydraulic piston-cylinder unit (45, 46) interacting with the screw drives for effecting the closing force build-up. To ensure a dimensioning of the actuating drive of the screw drives substantially in accordance with the requirements for rapid opening and closing motions while the hydraulic piston-cylinder unit maintains a high closing pressure, it is proposed to form the hydraulic piston-cylinder unit of one or more pistons and hydraulic cylinders, with the admission of pressure medium for effecting the closing pressure build-up being effected by piston-cylinder units which are driven by the screw drives via interposed pressure transmitting devices (19).

摘要： A mold closing apparatus and process for use with an injection molding machine are described. The mold is opened and closed by hydraulic pressure. The disclosed apparatus and method relate to the use of an immobile differential piston within a displaceable, double-action differential piston which moves within an immobile piston cylinder. This arrangement permits the use of smaller diameters to produce the necessary closing force. The immobile differential piston contains the necessary hydraulic passage for routing hydraulic fluid to the appropriate surfaces for exerting opening and closing forces. The use of a plurality of displaceable, single-acting pistons in parallel with the differential piston further reduces the diameters needed for exerting the claim force. Locating these single-acting pistons within the support column cylinders makes for an ever more compact apparatus.

摘要： A clamping unit, particularly for an injection molding machine, includes at least one moving platen which is moveably arranged on a frame element. At least one hydrostatic support is provided in an area between the platen and the frame element for facilitating back and forth displacement of the moving platen to thereby avoid speed-dependent friction values. Operation of the clamping unit is realized by building up pressure in a hydrostatic support before the moving platen is initiated for displacement so that the moving plate is slightly raises platen in relation to the frame element. After displacement of the moving platen, the pressure in the hydrostatic support is decreased again.

摘要： An apparatus for closing a mold having a pair of mold halves has a housing, a fixed support block on the housing carrying one of the mold halves, an abutment block on the housing, and a support block movable on the housing between the fixed support block and abutment block in a direction toward and away from the fixed block and carrying the other of the mold halves. A frame has at least one plate lying in a vertical plane generally parallel to the axis and formed with a pair of stiff upwardly extending upper arms, a pair of stiff downwardly extending lower arms below the respective upper arms, and an elastically deformable web extending in the direction between the upper arms and the lower arms. Anchors, e.g. bolts, fix one of the upper arms to the fixed support block and the other of the upper arms to the abutment block. A main actuator effective in the direction is braced between the movable support block and the abutment block and can expand to press the other mold half in the direction against the one mold half with elastic deformation of the web and to spread the upper arms. A secondary actuator braced between the lower arms can be expanded to push the lower arms apart in the direction and thereby urge the upper arms together.
