An injection molding device for manufacturing of multi-component plastic parts includes at least one first material component and at least one second material component. The injection molding device comprising a transfer means being designed to in the open position of the injection molding device transfer first injection molded material components from at least one group of first cavities into the at least one group of second cavities by rotation.

An injection mold for the manufacturing of at least one tubular plastic part, including a first mold half including a first mold plate and a second mold half including a second mold plate arranged displaceable with respect to each other in an axial direction (Z) between an open and a closed position. The injection mold includes at least one core protruding from the first mold plate and the second mold plate including at least one cavity suitable to receive the core to form a molding cavity in the closed position of the injection mold for receiving molten plastic material therein to form the tubular plastic part. A bushing is arranged in the second mold half adjacent to a dorsal end of the cavity at least partially displaceable with respect to the second mold plate, the bushing including a bore in the closed position suitable to receive a tip of the core.

Proposed is an apparatus and method for manufacturing automotive interior materials. The apparatus includes a first mold unit provided with a first molding surface and a gate disposed on the first molding surface, wherein a skin is set on the first molding surface. The apparatus further includes a second mold unit provided with a second molding surface facing the first molding surface, and configured to provide an opening exposing an edge of an edge portion of the set skin along a periphery between the first molding surface and the second molding surface when the second mold unit is combined with the first mold unit, and a sealing block provided with a tip portion disposed along the opening when the first mold unit and the second mold unit are combined.

A plastic injection tool for producing a closure cap is divided into first and second mold halves that can be moved relative to one another and an injection nozzle is formed in the first mold half, and sliding jaw tool parts are formed in the second mold half, radially outside a central tool core, which can simultaneously be moved in an ejection direction of the produced closure cap and perpendicular to the ejection direction. A respective partial ejection contour of the cap body is formed in the sliding jaw tool parts. An ejector is also provided for ejecting the produced closure cap. Partial injection contours that are different from one another are formed in sliding jaw tool parts, and a sliding jaw tool part is in contact with the tool core in two regions lying after one another in the ejection direction, before the ejection of the closure cap.

A mold includes a core in which a molded product is formed, the core comprises a cored body and a sliding core on the core body, separable from the core body in a first direction with respect to the core body, and an ejector to press the sliding core in the first direction to separate the molded product formed in the core from the core. The ejector includes a driver positioned below the core and movable toward a lower surface of the core in the first direction or away from the lower surface of the core in a direction opposite to the first direction, and a rod movable in the first direction to press the sliding core to be separated from the driver or movable in the direction opposite to the first direction to couple the sliding core with the driver, and the rod is movable further in the first direction than the driver.

A molding unit has a first molding station having a first mold having a first mold cavity, a second molding station having a second mold having a second mold cavity, a transfer unit having a support and at least a first core extending from the support. The transfer unit is arranged for moving the first core into a first molding position at the first molding station and into a second molding position at the second molding station. The first core extends into the first mold cavity when the first core is in the first molding position and into the second mold cavity when the first core is in the second molding position. A core actuation unit is arranged so that at least at the first molding station the first core is moved relative to the support from a first core position into a second core position when the first core is moved into the first molding position.
