Abstract
A mold apparatus for forming parts by reacting foam precursors in a mold cavity part closed by a cover has a mold breaker assembly including a member for holding a molded foam product in the mold cavity part as the cover is removed for part demolding. The member defines a slide for movement of the cover with respect to the mold cavity part to break adhesion of the cover from the top of the molded part while the molded part is firmly held in the mold cavity part. The mold breaker assembly includes a lift handle on the cover which is used to open the cover once the adhesive forces are broken so as to expose the molded part for demolding without scraping against the mold cavity part.
