Embodiment Construction

[0035] figure 1 It is a perspective view seen obliquely from above on the right side, showing an embodiment of the molding device 1 in an open state. The molding device 1 comprises a mold middle part 2 rotatable about an axis of rotation 9 (z direction), which has four inner mold halves 4a, 4b, 4c, 4d arranged on sides 3a, 3b, 3c, 3d and a first outer mold half. The mold and second outer mold halves 5a, 5b, the first outer mold half and the second outer mold half are movable relative to the mold middle part 2 in the axis x direction along a beam 15 (not shown in detail) of the injection molding machine. On the inner half-moulds 4a, 4b, 4c, 4d there are provided cores 6 protruding outwards. The core 6 can be used, for example, for injection molding (injection core) and / or blow molding (blow core) of parts made of plastic. Other implementations are possible.

[0036] The mold center 2 is mounted by means of a holding device relative to the beam 15 or frame of the injection mo...

Abstract

The invention relates to a molding device (1) for producing a product (12) by means of injection molding. The molding device (1) comprises a central mold part (2), which can be rotated about a rotational axis (9) and which comprises at least one inner mold half (4a-4d) arranged on the central mold part (2), and at least one outer mold half (5a, 5b), which interacts with the inner mold half (4a-4d)in order to form cavities in a closed configuration of the molding device (1) and which is arranged in a movable manner relative to the inner mold half (4a-4d) in a first direction (x). Furthermore,at least one first connector element (8) arranged on the central mold part (2) and at least one second connector element (10) arranged on the outer mold half (10) are provided, said second connector element (10) being operatively connected to the first connector element (8) at least in a closed configuration of the molding device (1).

Description

technical field [0001] The invention is in the field of devices for the manufacture of hollow products from plastic by injection and blow molding. Background technique [0002] Molds and mold usage are a significant cost item when manufacturing products from plastics, eg by injection molding or blow molding. In particular, it is worth pursuing the shortest possible cycle times in order to increase production efficiency. [0003] Various molding devices with a rotatable mold center are known from the prior art. A mold middle part rotatable about an axis of rotation is generally mounted between two outer mold halves movable along the axis of the injection molding machine, where the outer mold halves cooperate with the sides of the mold middle part to form the cavity. By using a rotatable mold center, a considerable increase in production efficiency and at the same time a space-saving construction can be achieved. [0004] In manufacturing processes involving blow molding mo...
