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： An injection molding machine has a machine frame, a stationary and a movable die platen, as well as a front plate supporting a closure mechanism. The front plate on which the movable die platen is supported via the closure mechanism and the stationary die platen are without bars and connected exclusively via the machine frame. The closing force occurring during the closing process and the lifting force occurring during the injection process between the front plate and the die platen are borne only by the machine frame. The movable die platen is guided on at least one rail supported on the machine frame. The closure mechanism is a toggle joint whose levers are rotatably articulated, on the one hand, at the movable die platen and, on the other hand, at the front plate.

摘要： A device for closing molds of an injection molding machine for plastic which includes a stationary end plate and a mold clamping plate displaceable on traverses. The stationary end plate is connected to the clamping plate by a toggle mechanism having a double toggle lever. The double toggle lever is actuatable by at least two drive units arranged between the end plate and the mold clamping plate, parallel to a main axis of the machine.

摘要： A friction clamp assembly for securing a mold of an injection molding machine in a closed position includes a column rigidly secured to a moving platen carrying a mold half and a gripper bush assembly for frictionally engaging and locking the column in a desired position. The clamp assembly further includes a clamp piston for clamping the moving platen in a mold closed position. The clamp assembly transmits a clamping force to portions of a moving platen other than end portions via the column so that platen parallelism is maintained during closing, injection and hold pressure portions of a molding cycle while platen bending is substantially avoided.

摘要： There is provided a direct mold clamping apparatus with an ejector, which is capable of uniformly applying a mold clamping force to a movable platen and is simple in construction and compact in size. A hollow cylindrical push member (12) and a movable platen (3) are coupled to each other through a single junction plane, in the form of an annular ring. A driving force transmitted through the push member is applied uniformly to the movable platen. The ejector (1) of the mold clamping apparatus (2) is provided with a ball nut (7) disposed in a hollow portion of the push member. A ball screw (6), which mates with the nut, is coaxial with a ball screw (8) for mold clamping, and has a front end fixed to an ejector pin (4) and the rear end portion removably fitted in a hole (8a) in a front end portion of the mold clamping ball screw. Thus, the axial length of the mold clamping apparatus is reduced.
