Problems solved by technology

[0005] A disadvantage of this method and arrangement is the loss of time for cooling and removing the preforms and plastic molded parts which remain after the first and second injection molding steps in the outer mold half
Another disadvantage is that four inner mold halves with unique forms are required to carry out the method and operate the machine as required

Abstract

The invention relates to a method for manufacturing a multi-component plastic molded part (200) and a tool system hereto, wherein the method comprises a first injection molding step (10) for molding at least one preform (11) and a second injection molding step (20) for molding at least one second component (21) onto the preform (11), whereas the first and second injection molding step (10, 20) areperformed with an injection molding machine comprising a first outer half-mold (12) and at least one sec- ond outer half-mold (22) positioned on opposite sides of a rotatable carrier-block (40), thecarrier-block (40) having at least four side faces (41) each comprising an inner half-mold (42), and whereas the method comprises at least the following steps: a) simultaneous injection molding of thepreform (11) in the first injection molding step (10) and of the second component (21) in the second injection molding step (20); b) opening the injection molding machine by moving the first and second outer half-mold (12, 22) spaced apart from the rotatable carrier-block (40); c) carrying the preform (11) out of the first injection molding step (10) and carrying the plastic molded part (200) outof the second injection molding step (10) by rotating the carrier-block (40), d) cooling the preform (11) while carried by the inner-half mold (42) on the carrier- block (40) by means of a cooling medium (32) and removing the plastic molded part (200) from the inner-half mold (42) on the carrier- block (40) by means of a handling means (51).

Description

technical field [0001] The invention relates to a method for producing a multi-component plastic molded part, wherein the method comprises a first injection molding step for molding at least one preform and for molding at least one second component to a second injection molding step on the preform, wherein the first injection molding step and the second injection molding step are performed by an injection molding machine comprising a support positioned rotatably A first outer mold half and at least one second outer mold half on opposite sides of a block, the bracket block having at least four sides, each side comprising an inner mold half. Furthermore, the invention relates to a tool system with an injection molding machine. Background technique [0002] An injection molding machine for plastic parts is known from DE 10 164 900 B4. The machine includes a first outer mold half and a second outer mold half carried on plates on opposite sides of a rotatable support element. ...
