摘要： An injection arrangement for a moulding machine includes a moulding compound reservoir and an injection unit. The moulding compound reservoir is configured to provide a plasticized mass and to push out the plasticized mass through a discharge opening, and a connecting device is coupled to the discharge opening of the moulding compound reservoir and a feed opening of the injection unit, and is configured to direct the plasticized mass from the moulding compound reservoir to the injection unit. The connecting device includes an articulated element, and a relative movement between the moulding compound reservoir and the injection unit can be performed with the articulated element.

摘要： A method of finding a target conveying capacity of a pumping includes a temperature-control flow through a temperature-control channel carried out according to a control variable by using a throttle as an actuating element such that a temperature-control volume flow remains substantially constant. A conveying flow of the pumping system is measured, and a pump starting from a starting conveying capacity independent of the control of the temperature-control volume flow is driven such that a conveying capacity of the pumping system is reduced to a reduced conveying capacity. Then, a check is made to find whether the conveying flow remains substantially constant and, if this is the case, the reduced conveying capacity is determined to be the target conveying capacity or. If this is not the case despite the control of the temperature-control volume flow, the starting conveying capacity is determined to be the target conveying capacity.

摘要： A measuring arrangement for a shaping machine includes a measuring diaphragm deformable by a force action, a measuring device for metrological detection of a deformation of the measuring diaphragm with the output of a measurement signal, and an evaluation device connected to the measuring device. The evaluation device, in the course of a first calibration, can convert the measurement signal originating from the deformation of the measuring diaphragm with a force from a first force value range into a first output signal, and the first output signal is in a previously defined value range. The evaluation device, in the course of a second calibration, can convert the measurement signal originating from the deformation of the measuring diaphragm with a force from a second force value range differing from the first force value range into a second output signal, and the second output signal is in the previously defined value range.

摘要： An injection unit for a shaping machine includes an injection piston arranged displaceably in an injection cylinder and at least two drive units for displacement of the injection piston. Each of the at least two drive units is lubricated by an oil chamber which is oil-tightly sealed off in relation to the surroundings, and each oil chamber holds an oil volume, above which is arranged an air volume. The air volumes of the oil chambers are connected together in air-conducting relationship by a connecting conduit.

摘要： An injection unit for a shaping machine includes an injection element suitable for introducing a plasticized material into a mould 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 so that deformations of the bearing element are not transmitted to the transmission element or are transmitted to a reduced degree.

摘要： A temperature control apparatus includes a temperature control branch connected to a feed line for a temperature control medium, a pump system including a pump for conveying the medium, a pump open-loop or closed-loop control device for controlling the output of the pump system, a throttle device having a variable degree of opening for throttling a quantitative through-flow of the medium in the temperature control branch, and an open-loop or closed-loop control device with the degree of opening of the throttle device as a setting value and with a control variable from the group: degree of opening of the throttle device, temperature, temperature difference, through-flow, pressure or a physical value to be derived from that group. The pump open-loop or closed-loop control device provides for open-loop or closed-loop control of the delivery output of the pump system depending on the degree of opening of the throttle device.
