Tool for the injection molding of plastic molded parts and method for moving a slide of a tool half of the tool

A method for moving a plurality of slides of a first of two tool halves of a tool for the injection molding of plastic molded parts, the tool comprising the two tool halves, which are moveable in relation to each other, wherein the two tool halves include is a nozzle component and an ejector component, wherein the first of the two tool halves comprises a mold plate carrying at least one mold insert, which has a multiplicity of mold cavities, or a mold plate with a mold insert support platen, which carries at least one mold insert with a multiplicity of mold cavities, wherein the multiplicity of mold cavities of the first of the two tool halves are configured to form molded parts in conjunction with complementary cavities present on a second of the two tool halves, wherein the mold insert of each mold cavity of the multiplicity of mold cavities is assigned a corresponding one of a plurality of slides, each of the plurality of slides is arranged movably between two positions over or in a cavity-side surface of the mold insert, wherein each of the plurality of slides has at least one guide element in engagement with a counterpart guide element in the mold insert, and wherein a connection bolt extends from each of the plurality of slides in a direction of the mold plate or of the mold insert support platen and each of the plurality of slides is guided in a guide groove of a rotary ring, wherein a plurality of connection bolts of the plurality of slides are arranged circumferentially along the circumference of the rotary ring, distributed in a corresponding number of guide grooves, and wherein the rotary ring is connected to a drive ring arranged on the mold plate or the mold insert support platen, the method comprising:

• rotating the drive ring arranged on the mold plate or mold insert support platen together with the connected rotary ring;
• guiding the plurality of connection bolts, which are connected to the plurality of slides, in the corresponding guide grooves of the rotary ring;
• and
• driving the plurality of slides, by the at least one guide element guided in the counterpart guide element, from a starting position to an end position.

A method for pivoting a portion of a one-piece molded part present in an ejector component, wherein the portion is a second portion of the one-piece molded part which is connected to a first portion of the one-piece molded part via a hinge, the method comprising:

• a) deploying an ejector pin, which is arranged under the second portion, to release the second portion from the mold cavity;
• b) moving a slide from a starting position by rotating the drive ring arranged on the mold plate or mold insert support platen together with the connected rotary ring, guiding a connection bolt, which is connected to the slide, in corresponding guide grooves of the rotary ring, and driving slide, by at least one guide element guided in a counterpart guide element, from the starting position to the end position, wherein
• a slide tip of the slide moves under the second portion of the molded part and sets the second portion of the molded part upright, and,
• during a continuous onward movement of the slide to the end position, slide tines of the slide travel around the ejector pin and the slide tip folds the second portion of the molded part over, and the slide tines travel over the second portion of the molded part such that the second portion of the molded part comes to lie on the first portion of the molded part,
• c) moving the slide back to the starting position by rotating the drive ring in an opposite direction to step b), before ejection of the molded part takes place by deployment of the ejector pin, which is present under the first portion of the molded part and thus release the molded part from the mold cavity.
