A method is provided for producing a multi-section plastic component in which a first plastic injection-molded individual part and a second plastic injection-molded individual part are formed. The plastic injection-molded individual parts are joined by injecting a plastic moulding compound. The plastic molding compound is a non-elastomeric thermoplastic and forms a plastic connecting component following a curing process. The plastic injection-molded individual parts and plastic connecting component are then at least partially painted.

An injection mold for producing a double walled drinking vessel includes first and second mold portions. The first mold portion forms a first and second cavities corresponding to the outer shape of the outer container and the outer shape of the inner container, respectively. The first and second cavities are located concentrically with respect to a central axis. An index plate is rotatable and axially movable along the central axis relative to the first mold portion. The index plate includes a first core and a second core. The first cavity has a first cavity injection gate for injecting mold material into the first cavity for forming the outer container. The second cavity has a second cavity injection gate for injecting mold material into the second cavity for forming the inner container. The first cavity has a further injection gate for injecting joint material for joining the outer and inner containers.

Container of a bag-in-container type, wherein a neck region of the container is provided with at least one opening extending substantially radially there through, into a space between the outer container and an inner container adjacent thereto, wherein the neck region is provided with coupling elements, preferably at opposite sides of the at least one opening, seen in circumferential direction, for coupling of a connecting device to the container for introducing a pressure fluid through the at least one opening into a space between the inner and outer container.

The invention relates to a retaining device for a rotatable center block in an injection molding device, comprising a lower rotary plate rotatable about an axis of rotation and driven by a motor, the lower rotary plate being used for retaining the rotatable center block. The retaining device comprises a lower cross member, which is mounted movably in the longitudinal direction (x) on guide rails while supported on a machine bed of the injection molding device by means of first bearing blocks. The retaining device can have two bearing blocks, by means of which the lower cross member is supported in the circumferential direction relative to lower beams of the injection molding device. For a further increase in efficiency, the center block has a main body made of a material of lower density than a coupling plate operatively connected thereto.

An assembly appliance for mould tool parts of an injection moulding tool is disclosed, the assembly appliance including an assembly plate configured for insertion into an injection moulding machine and including a tool carrier for receiving first mould tool parts to be assembled; and an assembly frame having a guide system for a translatory displacement of the assembly plate along a longitudinal extension of the assembly frame, and a support device for stationary support of a second mould tool part which corresponds to at least one of the first mould tool parts.

An injection molding device (1) includes a center part (3) and a rotating device (2) for rotating the center part (3) in the injection molding device (1). The rotating device (2) includes a base (4) supported with respect to an injection molding machine. A thereto attached column (5) extends to an axial direction (z) above the base (4). A sleeve (6) coaxially surrounds the column (5) and is at least partially arranged in the center part (3). The sleeve (6) rotates with the center part (3) around the column (5). The column (5) is arranged removable with respect to the center part (3).

The present invention relates to a process for the production of reinforced plastics components. The process includes a) provision of at least one reinforcing material in a cavity of a molding device, b) provision of at least one starting material in a container, c) insertion of the container into the molding device, d) introduction of the at least one starting material from the container into the cavity, wherein the at least one starting material penetrates at least to some extent through the at least one reinforcing material, e) hardening of the at least one starting material with the at least one reinforcing material to give a reinforced plastics component, and f) demolding of the reinforced plastics component. The invention further relates to a device and to an assembly for the production of reinforced plastics components.

Container of a bag-in-container type, wherein a neck region of the container is provided with at least one opening extending substantially radially there through, into a space between the outer container and an inner container adjacent thereto, wherein the neck region is provided with coupling elements, preferably at opposite sides of the at least one opening, seen in circumferential direction, for coupling of a connecting device to the container for introducing a pressure fluid through the at least one opening into a space between the inner and outer container.

What is presented is a method of forming a closure with a sealing gasket in an injection molding machine that has a center rotating cube. The center rotating cube comprises a plurality of mold back halves each comprising cores and a thread unscrewing mechanism. Each core is shaped to form a closure that has a thread and an anti-rotation feature. The method comprises the steps of forming a closure with a through hole, rotating the core to create a gap between the formed closure and the core, and injecting a compressible material through the through hole and into the gap to form a sealing gasket.

The present invention addresses the problem of manufacturing first and second members with different materials when molding injection molding body one after another using first to third molds disposed at 120 degrees from each other on a turntable that performs reciprocating motion at 120 degrees and using fourth to sixth molds provided opposite to the first to third molds, respectively. According to the solution, first to third injection devices are disposed on the sides of fourth to sixth molds, respectively, the first injection device is caused to perform primary injection to mold a first member, and the second and third injection devices are caused to perform primary injection to mold a second member and secondary injection to integrate the first and second members with each other, whereby the first and second members can be manufactured with different materials one after another.
