Introduction to the Rotational Drive Technology of Screw Ejection Molds Using AC Servo Motors【Molds】

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 internal 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 rotation drive mechanism into the mold, allowing the gear to rotate as the mold opens, thus driving the core's rotation. While this ensures reliable operation due to the uniform action of the gears, it also requires a separate rotation drive mechanism for each individual mold, making the mold itself more complex and increasing costs. On the other hand, systems that use motors benefit from the separation of the screw removal mold and the rotation drive unit. The rotation drive unit is installed as part of the molding machine's mechanism and function, resulting in a simpler configuration for the mold compared to gear-type systems. In environments where multiple molds of different types are exchanged to produce a variety of caps, we believe this system offers high flexibility.
