Injection molding device

A process for the production of a complex injection molded product by injection molding, comprising the following process steps:

• a. inserting by a handling system components (19) into first cavity segments (9) of a first inner mold plate (8) of a first part (7) of a central part (5) of an injection molding device (1) in a first production level (16) at a 0° position;
• b. after step a, opening the injection molding device (1) by moving a first outer mold half (3) and a second outer mold half (4) apart from each other, away from the central part (5) arranged there between in a center position;
• c. after step b, linearly displacing second inner mold plates (11) in a radial direction away from thereto related side faces of a second part (5) of the central part (5) with respect to a rotation axis (6) from an inner into an outer position;
• d. after step c, rotating the first part (7) with the thereto attached first inner mold plates (8) together with the second outer mold plates (11) held by a guiding means (22) in a first direction about the axis of rotation (6) by an angle of 90° to a 90° position;
• e. after step d, linearly displacing the second inner mold plates (11) from the outer position into the inner position thereby bringing the external component into a first cavity type formed between the first inner mold plates (8) and the second outer mold plate (4) by first cavity segments;
• f. after step e, injection molding a first layer of material onto the external component resulting in a first intermediate product;
• g. after sufficient curing of the first material component, opening of the injection molding device (1) and rotating the first and the second inner mold plates (8, 11) by another 90° around the axis of rotation (6) to a 180° position, the first intermediate product thereby remaining in the first inner cavity segments (9) arranged at the upper part (7) of the central part (5);
• h. after step g, by a handling device moving the first intermediate products from the upper production level (16) into corresponding second inner cavity segments (12) arranged at the second inner mold plates (11) in a lower production level (17);
• i. after step h, rotating the first and the second inner mold plates (8, 11) by another 90° around the axis of rotation (6) to a 270° position;
• j. after step i, after closing of the injection molding device (1) the intermediate products are arranged in a second cavity type formed by second inner cavity segments (12) of the second inner mold plates (11) and the second outer cavity segments (14) of the first outer mold plate (3);
• k. after step j, injection molding of a second layer of material onto the first layer of material, resulting in a second intermediate product;
• l. after step k, rotating the second inner mold plates (11) by another two times 90° steps such that the thereto attached second intermediate product is introduced into a third cavity type formed third cavity segments (15) arranged at the lower part (10) and the lower part of the second outer mold plate (4);
• m. after step l, injection molding of third material component onto an outer surface of the second intermediate product forming a final product;
• and
• n. after step m, opening the injection molding device (1) and removing the final product.
