TOOL FOR INJECTION MOULDING OF MOULDED PLASTIC PARTS AND METHOD FOR MOVING A SLIDE OF A TOOL HALF OF THE TOOL

摘要

The present invention provides a tool (1) for injection molding plastic molded parts, which tool has two tool halves (2, 3) which can be moved relative to one another. One of the mold halves (2, 3) has a mold plate (9) which carries at least one mold insert (5) with a plurality of mold cavities (8), or a mold plate (9) with a mold insert carrier plate (10) which has at least one Mold insert (5) with a plurality of mold cavities (8), the mold cavities (8) being designed to form molded parts (20) with complementary cavities present on the second mold halves (2, 3). The mold insert (5) has a slide (6) assigned to each mold cavity (8), which is arranged movably above or in a cavity-side surface of the mold insert (5). The slide (6) has at least one guide element (6 ') which engages with a counter-guide element (19) in the mold insert (5), with the slide (6) extending in the direction of the mold plate (9) or the mold insert carrier plate (10) a connecting bolt (14) extends which is guided in a guide groove (16) of a rotating ring (13). A plurality of the connecting bolts (14) of a plurality of slides (6) are arranged circumferentially in a corresponding number of guide grooves (16) distributed along the circumference of the rotary ring (13), and the rotary ring (13) is connected to one on the mold plate (9) or the mold insert carrier plate (10) arranged drive ring (12) connected. Methods are also disclosed for moving the slide (6), in particular for pivoting a molded part section and for designing the mold cavity (8) in a mold half.
