Patent ID: 7140866

Claim:
A self-alignment stage for compression-forming machines, comprising: an outer frame comprising a body having a space therein; a plurality of outer connectors protruding from a side surface of the body of the outer frame so as to support the body on a support base of a compression-forming machine; an inner frame placed in the space of the outer frame such that the inner frame executes a horizontal translational motion and a rotational motion; and a plurality of inner connectors to connect the inner frame to the outer frame while allowing the inner frame to execute the horizontal translational motion and the rotational motion on a plane with respect to the outer frame, whereby the material seated on a lower mold on the inner frame is self-aligned by elasticity of the inner and outer connectors, so that an upper surface of the lower mold is in parallel surface contact with a lower surface of an upper mold when the material is compression-formed by the upper mold.
