Abstract:
The present disclosure relates to an injection moulding device with a first mould half and a second mould half, arranged movably with respect to said first half, and a central mould half arranged between said first and second halves and rotatable about an axis of rotation. Arranged to the side of the central mould half is a further processing device.
Abstract:
The invention concerns a device for injection moulding (1) comprising a first fixed half-mould (3) and a second half-mould (5) mobile in direction (y) of the side blocks (4) of an injection moulding machine (2). Between the first and the second half-moulds are mounted first and second immediate elements (6, 7) mobile in the direction of the side blocks (4). The first and the second intermediate elements (6, 7) comprise each a mould support (12, 13) pivoting relative to a base (14, 15, 31, 32) about a pivoting axis (8, 9). Centering elements (26, 27) upon the opening and closure of the injection moulding devices (1).

Abstract:
In a method for the internal cooling of a rotating object (4), liquid gas from at least one inlet channel (61) in a fixed object (5) is pressed into a ring-shaped groove (62) located between the fixed object (5) and the rotating object (4). From the ring-shaped groove (62) the liquid gas is pressed into at least one channel (63, 64.1, 64.2) in the rotating object (4) and brought to a part to be cooled (15). The liquid gas, upon contact with the part, evaporates and expands while absorbing heat, thereby cooling the part. The area surrounding the part to be cooled (15) may be designed as an expansion chamber (65). The method can be used to cool molded parts in injection molding machines with rotating molds (1), thereby achieving shorter cycle times.
Abstract:
A method for manufacturing a multilayer tube shoulder wherein a first material component is injected into a cavity (22) and then removed from the cavity on a support (12) while in a partly-plastic state. Thereafter, following insertion of the first material component into a second cavity (23), a second material component is injected around the first material component, and thereby leads to a positive connection between the first and second material components.
