Introduction to the rotational drive technology of screw extraction molds using AC servo motors.

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, causing the gear to rotate when the mold opens, thus enabling the core's rotational drive. While the uniform operation provided by the gear ensures reliable performance, it requires a separate rotational drive mechanism for each mold, making the mold itself more complex and increasing costs. On the other hand, using a motor allows for the screw removal mold and the rotational drive part to be considered separately, which is advantageous. The rotational drive part is installed as part of the molding machine's mechanism and function, resulting in a simpler structure for the mold compared to the gear type. In environments where multiple molds of different types are exchanged to produce a variety of caps, we believe this system offers high flexibility.
