Abstract:
A rotating apparatus includes a rotary plate for mounting a tool part, a rotary shaft connected to the rotary plate, a rotary feedthrough including a stator, and a rotor connected to the rotary shaft for feeding through at least two media to the rotary plate. The rotor has a first rotor part for feeding through a first medium and a second rotor part for feeding through a second medium, and the first and the second rotor parts are thermally separated from each other. A first media routing for the first medium is in the form of a hose and/or pipe for the first medium from the first rotor part past the connecting part to the rotary plate. A connecting part is non-rotatably connected to the second rotor part and the rotary shaft. The hose and/or pipe extends from the first rotor part.

Abstract:
A carousel-like continuous molding system includes an arrangement of inclined feed channels. Each of the feed channels has a controllable valve therein positioned upstream of an inlet to an associated mold cavity. The valve is controllable so that adjustments may be made in real time to achieve or maintain delivery of molten polymeric material to the mold cavity at constant pressure.
Abstract:
In an aspect, an injection molding machine is provided and incorporates a mold block with a plurality of sides including an injection side at which hollow parts are formed in mold cavities, a first post-mold cooling side whereat the hollow parts are cooled, and a part transfer side where parts are transferred out of the mold block. Optionally additional post-mold cooling sides are provided. A takeout structure is provided to remove the hollow parts from molding cores on the injection side, to transfer the hollow parts to the first post-mold cooling side, and to subsequently transfer the hollow parts to the part transfer side. The takeout structure holds the hollow parts by their neck portions and cools their neck portions.
Abstract:
A fixed mold and a movable mold as joined together are configured to nip a terminal base of a tuning-fork terminal between a terminal base receiving portion and a terminal base abut portion with the tuning-fork terminal being protruded outside a cavity of the fixed mold.
Abstract:
The invention relates to a retaining device (5) for a rotatable center block (17) in an injection molding device (1), comprising a lower rotary plate (14) rotatable about an axis of rotation (13) and driven by a motor (15), the lower rotary plate being used for retaining the rotatable center block (17). The retaining device (5) comprises a lower cross member (7), which is mounted movably in the longitudinal direction (x) on guide rails (9) while supported on a machine bed of the injection molding device by means of first bearing blocks (8). The retaining device (5) can have two bearing blocks (16), by means of which the lower cross member (7) is supported in the circumferential direction relative to lower beams (4) of the injection molding device. For a further increase in efficiency, the center block (17) has a main body made of a material of lower density than a coupling plate (23) operatively connected thereto.
Abstract:
The invention relates to a rotation device (1) for rotating the center part (2) in an injection-molding device. The rotation device comprises a column (3) which is non-rotatably mounted in the interior of the center part (2) and a sleeve (4) surrounding the same which is mounted such as to rotate with the center part (2), said sleeve (4) and said column (3) being operatively interconnected via a drive.
Abstract:
An apparatus for manufacturing the ends of electric cables, which comprises a section for injection moulding on at least one end, a first section comprising means for applying electrical connection elements to one end of the cable and, optionally, a second section for applying further electrical connection elements to the remaining end of the cable, and means for testing the cable prior to its output from the apparatus, in which retaining means for both ends of the cables in all the manufacturing sections and means for moving said ends from the retaining means of one section to the retaining means of the next section are also present. The moulding section comprises a plurality of moulds, with an injector for each mould, mounted on platform with which they can be rotated along a circumference.
Abstract:
The invention relates to a method for the production of form parts from multi-component reactive plastic material, especially from polyurethane, wherein a plurality of moulds are moved by means of mould carriages (1) at least temporarily along a closed, preferably oval, production line (2). To allow a simple and quick import and export of mould carriages in the respectively out of the production line the invention proposes that the mould carriages (1) are provided with rolls (3) and are moved on a stationary ground (4) by the same and that a plurality of supply carriages (6) are arranged along the closed production line (2) at a conveying element (5), which supply carriages (6) are moved by means of the conveying elements (5), wherein a mould carriage (1) is approached to a not occupied supply carriage (6) and is coupled with the same to introduce the mould carriage (1) into the production line (2), wherein for the movement along the production line (2) the mould carriage (1) is guided and moved by the supply carriage (6) in a coupled state between the mould carriage (1) and the supply carriage (6) and wherein the mould carriage (1) is decoupled from the supply carriage (6) and is moved away from the production line (2) for taking the mould carriage (1) out of the production line (2), wherein here the mould carriage (1) is moved with its roils (3) on the stationary ground (4). Furthermore, the invention relates to a respective device.
