  • Publication number: 20240269898
    Abstract: A tie-bar-less clamping unit for a moulding machine includes a machine frame formed for absorbing clamping forces, and a fixed platen arranged stationary in relation to the machine frame. A movable platen can move relative to the machine frame, and at least one push rod is preferably arranged substantially centrally with respect to the movable platen. At least one pressure pad is arranged between the push rod and the movable platen.

  • 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.
