  • Patent number: 11225007
    Abstract: A method for moving a movable mold mounting plate of a molding machine, wherein the movable mold mounting plate is movable relative to a stationary mold mounting plate and the mold mounting plates are kinematically connected to each other, wherein molding tool parts arranged on the mold mounting plates are brought into abutment to each other in a closed state and wherein the movable mold mounting plate is moved by a drive mechanism and/or the stationary mold mounting plate is moved by an injection device such that, when reaching a predeterminable distance of the mold mounting plates relative to each other, a parameter representing a tilting movement of the mold mounting plates relative to each other is less than or equal to a presettable value.

  • Patent number: 11141894
    Abstract: An injection unit for a shaping machine includes an injection element suitable for introducing a plasticized material into a mold tool by a linear movement of the injection element. The injection element is coupled in linear motion-transmitting relationship to a bearing element, and at least two linear drives are adapted to exert a force on the injection element by the bearing element. The force can be transmitted by a transmission element from the at least two linear drives to the bearing element and thus to the injection element, and at least one clearance is arranged between the bearing element and the transmission element such that deformations of the bearing element are not transmitted to the transmission element or are transmitted to a reduced degree.

  • Patent number: 11141895
    Abstract: A shaping machine includes a stationary first mold mounting plate, a second mold mounting plate movable with respect to the first mold mounting plate, a tubular snorkel fixedly secured to the second mold mounting plate, and an injection unit for plasticizing and injecting a molding material. An abutment is designed so that, in the opened condition of the closing unit, the injection unit can be braced against the abutment, and so that, in a closed condition of the closing unit, the injection unit is freed from the abutment by the force action of the snorkel on the injection unit.

  • Patent number: 9914253
    Abstract: A closing unit of a shaping machine includes a moveable clamping plate, a push rod connected to the moveable clamping plate and having an outside profile, a divided locking nut provided with an inside profile, and a closing force mechanism for acting on the moveable mold clamping plate with a closing force. The push rod is lockable in a closed position of the locking nut by the cooperation of the inside profile and the outside profile with the closing force mechanism. For displacement of the locking nut between an opened and the closed position, a rotary drive is provided for rotation of a shaft, and at least one toothed rack cooperates with the shaft by way of a tooth arrangement and is connected to the locking nut.

  • Publication number: 20140234472
    Abstract: A closure unit of an injection molding machine has a fixed mold mounting plate, a moveable mold mounting plate, and at least one mounting element for mounting the fixed mold mounting plate to a machine frame. The at least one mounting element upon accelerations and decelerations of the moveable mold mounting plate to reach the closed position allows such movements of the fixed mold mounting plate relative to the machine frame that rotations and/or movements transversely relative to a machine axis of the fixed mold mounting plate relative to the moveable mold mounting plate are substantially prevented.
