Solving screw extraction molds with AC servo motor rotational drive technology #molds
GSH series
Here is an example of using an AC servo motor to drive the core mold that forms the internal screw part of the movable side and the fixed side mold. #MoldingMold
The unscrewing machine consists of a fixed side mold that forms the outer shape of the cap, a core mold that forms the movable inner screw part, and an AC servo motor that drives the rotation of this core. The rotation drive of the unscrewing mold is powered by the AC servo motor. “To create a cap through resin molding, a core mold with engraved screws is used. However, since the cap's screw has an internal thread with ridges, the core mold cannot be simply pulled out after resin filling. It is necessary to open the mold while rotating the core mold. A mold that requires such rotational operation during opening is called an unscrewing mold.” Note: It is possible with mechanical molds, molding molds, plastic molds, mold molds, and die-cast molds, but it seems that press molds and casting molds are currently not supported.

basic information
The screw removal machine consists of a fixed side mold that forms the outer shape of the cap, a core mold that forms the inner screw part on the movable side, and an AC servo motor that drives the rotation of this core. (Omitted) The AC servo motor is installed in the unit that attaches the movable side mold and drives the core mold via a sprocket and chain. The gear-type mechanism integrates a rotational drive mechanism into the mold, allowing the gears to rotate as the mold opens, thus enabling the core's rotational drive. While the uniform operation provided by the gears ensures reliable performance, it also necessitates a separate rotational drive mechanism for each mold, making the molds themselves more complex and increasing costs. On the other hand, systems that use motors benefit from the separation of the screw removal mold and the rotational drive unit. The rotational drive unit is installed as part of the molding machine's mechanism and functions, resulting in a simpler structure for the mold compared to gear-type systems. In environments where multiple types of molds are exchanged to produce a variety of caps, we believe this offers a highly flexible system.
