Method and tool system for manufacturing a multi-component plastic molded part

A method for manufacturing a plurality of plastic molded parts each comprising a preform and a second component via an injection molding machine that includes a first outer half-mold and a second outer half-mold positioned on opposite sides of a rotatable carrier-block, the second outer half-mold including a micro structure, the carrier-block having at least four side faces each comprising an inner half-mold, the method comprising:

• injection molding a first preform via a first injection molding step of the injection molding machine;
• opening the injection molding machine by moving the first outer half-mold and the second outer half-mold outwardly away from the rotatable carrier-block;
• carrying the first preform by rotating the carrier-block;
• streaming a cooling medium onto the first preform to cool the first preform while the first preform is carried by the inner-half mold on the carrier-block;
• injection molding at least one second component onto the first preform via a second injection molding step of the injection molding machine to form a first plastic molded part simultaneously with the injection molding of a second preform;
• opening the injection molding machine by moving the first outer half-mold and the second outer half-mold outwardly away from the rotatable carrier-block;
• carrying the second preform and carrying the first plastic molded part by rotating the carrier-block;
• streaming a cooling medium onto the second preform to cool the second preform while the second preform is carried by the inner-half mold on the carrier-block;
• and
• removing the first plastic molded part from the inner-half mold on the carrier-block by means of a handling arm,
• wherein the first injection molding step and the second injection molding step of the injection molding machine are performed simultaneously with at least one of:
• streaming the cooling medium onto one of the preforms;
• and
• removing one of the plastic molded parts from the inner half-mold on the carrier-block using the handling arm.
