Abstract: A device (1) and method for injection molding articles (25) with several plastic material components. The device (1) includes a fixed, first half mold (3), a second half-mold (6) that is movable relative to the first half-mold (3) for the purpose of opening and closing the device (1). The device also includes at least two further half-molds (10, 11), which are jointly movable relative to the first and second half-molds (3, 6), and which, in the closed position of the device (1), are situated between the first and the second half-molds (3, 6) such that cavities are formed in each of a first and a second parting plane (32, 33).

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 holding device (1) for injection molding mold halves (61.2) or their holders contains two displacement units (2.1, 2.2), on each of which a rotation unit (4.1, 4.2) is attached. On each rotation unit (4.1, 4.2) there are holders (5.1, 5.2). Into the space (d) between the two holders (5.1, 5.2) a die holder designed as a prism-shaped rotating block can be inserted. The die holder in the holding device (1) can be displaced in one direction (z) and can be rotated around a displaceable axis (42.1, 42.2), which is vertical to the one direction (z). The displacement units (2.1, 2.2) can be displaced relative to one another to permit rapid and easy changing of injection molding molds (62.1).
