Abstract: A method of manufacturing a molded part includes inserting melt into a cavity of a first tool part, and the first tool part and a second tool part are moved away from one another during or after the insertion of the melt by moving a second mold clamping plate relative to a first mold clamping plate such that in the first tool part or in the second tool part clearance space of a first or second cavity portion of the cavity is created, and a gap is formed between the first tool part and the second tool part. Melt is further inserted into the clearance space of the cavity, and the gap is bridged by an at least already partially solidified section of the melt. A holding force is transmitted from the second tool part to the first tool part through the partially solidified section of the melt bridging the gap.

Abstract: 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.

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 and wherein a drive mechanism for moving the movable mold mounting plate is provided, wherein molding tool parts arranged on the mold mounting plates are brought into abutment to each other in a closed state and wherein a temporally changeable tilting movement of the mold mounting plates relative to each other occurs by the movement of the movable mold mounting plate, wherein the movable mold mounting plate is moved by the drive mechanism and/or the stationary mold mounting plate is moved by an injection device in such a way that when reaching a predeterminable distance of the mold mounting plates relative to each other a parameter representing the tilting movement of the mold mounting plates relative to each other is less than or equal to a presettable value, preferably equal to zero.

Abstract: 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.

Abstract: A control device for a handling device includes a storage medium, a processing unit, an output for outputting signals, and an input for receiving signals from the handling device. A waiting phase is conducted before an actuation of an end-of-arm tool mounted to an end-of-arm of a handling arm. The signals received by the input represent a dynamic parameter of the end-of-arm and a threshold value corresponds to a specific dynamic parameter of the end-of-arm stored in the storage medium. The signals received by the input can be compared with the threshold value by a comparison unit of the control device, and an end of the waiting phase can be determined when reaching the threshold value. Depending on a curve of the dynamic parameter, the threshold value can be determined and the end of the waiting phase can be determined when reaching the threshold value.

Abstract: A protective cover for a plasticizing cylinder of a shaping machine has an elongate internal space which is enclosed by at least one wall and in which the plasticizing cylinder can be arranged. A terminal box for heating strips arranged on the plasticizing cylinder projects into the elongate internal space, and the at least one wall has an opening which is closed by an openable cover member. In an opened condition of the openable cover member, the opening allows access to the terminal box or the interior of the terminal box.

Abstract: A closing unit for a shaping machine includes mutually moveable mold mounting plates suitable for carrying mold tool portions, a first hydraulic cylinder adapted to apply a closing force to the mold mounting plates, a second hydraulic cylinder, and a pressure storage means connected to the first hydraulic cylinder and adapted to store a pressure prevailing in the at least one first hydraulic cylinder upon pressure relief as a storage means pressure. A hydraulic interconnection of the pressure storage means with the second hydraulic cylinder allows the storage pressure stored in the pressure storage means to be used for locking and/or unlocking the locking device.
