ABSTRACT:
A molding machine includes a drive unit for linearly moving a movable body, such as a movable platen of a clamping apparatus. The drive unit includes a linear 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 is connected to the movable body (movable platen). 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.
