Molding machine

Abstract

A molding machine includes a drive unit for rotating and linearly moving a movable body. The drive unit includes a linear motor and a rotary motor. The linear motor includes a linear movement body having moving-side magnetic-pole portions and supported in an axially movable manner and a stationary body having stationary-side magnetic-pole portions adapted to linearly move the linear movement body. The linear movement body has moving-side inclined surfaces on which part of the moving-side magnetic-pole portions are disposed. The stationary body has stationary-side inclined surfaces which face the moving-side inclined surfaces and on which part of the stationary-side magnetic-pole portions are disposed. The rotary motor is incorporated into the linear movement body and is adapted to rotate an output shaft connected to the movable body.
