specific Embodiment approach

[0047] Fig. 1 is an oblique view from above of an injection molding device 1, which is in an open state. FIG. 2 is a side view, and FIG. 3 is a front view of the injection molding device 1 shown in FIG. 1 . Some parts have been removed in Figure 3 to make the interior more clearly visible. FIG. 4 is an enlarged illustration of part A in FIG. 3 .

[0048] The injection molding device 1 has a first half-mold 2 and a second half-mold 3 connected to the first half-mold. Die platen 7. The first half-mould 2 and the second half-mould 3 have a first half-cavity 11 and a second half-cavity 13 on opposite sides 8, 9, respectively. In general, the mold platens 5, 7 and guide rods 6 constitute parts of an injection molding machine (not shown in greater detail). The middle mold half 4 , rotating with respect to the axis of rotation 19 , can be seen between the first and second mold halves 2 , 3 . As shown in this embodiment, the middle mold half 4 is arranged in a cuboid shape, so th...

Abstract

The invention relates to an injection moulding device (1) with a first mould half (2) and a second mould half (3), arranged movably with respect to said first half, and a central mould half (4) arranged between said first and second halves and rotatable about an axis of rotation (19). Arranged to the side of the central mould half (4) is a further processing device (21).

Description

technical field [0001] The present invention relates to injection molding of plasticized materials, especially plastics. Background technique [0002] Injection molds for producing objects from a large number of plastic parts or assemblies are known in the prior art. In addition to solutions based on a turntable arranged on the parting surface, molds with a cube-shaped rotating intermediate part are also known. [0003] Patent application US4734023 by Ferromatik Desma GmbH discloses an injection molding device having an intermediate part arranged between two outer parts that are movable relative to each other along the tie rods of the injection molding machine. The rotatable middle part is mounted floatingly on two independent guide rods parallel to the tie rods of the injection molding machine. The guide rod protrudes from a mold platen of the injection molding machine. This arrangement allows only small-scale midsections. [0004] Patent application US4444711 by Husk...
