Integrated Indexing Plate Drive Achieves Short Cycle Times

i-mold adds to its Servomold solutions portfolio a line-up of servomotor-powered indexing plate drives that can be fully integrated into multi-component injection molds in a space saving arrangement. Available in four standard system sizes, the units are suitable for plate weights up to 250 kg. They are built to provide fast and precise rotary motions to achieve short cycle times and smooth production workflows.

The indexing plate drives provide unlimited rotary motion through 360 degrees and beyond, offering a time-saving advantage as it eliminates the need to return to a zero position before a new cycle starts. The system is based on all-rotational action, consisting of the servo motor unit (SAK type), an elastic servo coupling (SEK type), the indexing plate drive (SID type) and the splined output shaft to the indexing plate. The system is firmly attached to the injection molding machine clamping plate, permitting indexing plate molds of similar size to be operated with a uniform indexing plate unit, i.e., without requiring a separate rotary mechanism for every mold. SID indexing plate drives come in four frame sizes and with two SAK servomotor units delivering different outputs. Depending on the combination, the system can actuate indexing plates with a maximum weight between 10 kg and 250 kg. All systems are equipped with a safety brake to prevent mold damage in the case of a power failure. The output shaft is splined but can be individually adapted at the customer's request.
