Abstract
An assembly for molding and demolding hardened cementitious products comprises a flexible mold and a demolding apparatus. The flexible mold has a top side with separate openings for receiving cementitious material therein for hardening thereof, an opposite closed rear side and a perimeter. The apparatus for demolding the hardened cementitious products from the flexible mold comprises a conveyor, a holding member, a clamp, and a movable member. The conveyor conveys the flexible mold. The clamp grips a portion of the perimeter. The holding member engages the mold. The movable member moves the clamp and the clamped portion of the mold about the holding member thereby disengaging the flexible mold from the cementitious material.
Claims15
An assembly for molding and demolding hardened cementitious products comprising:
- a flexible mold having a top side with separate openings for receiving cementitious material therein for hardening thereof, an opposite closed rear side and a perimeter;
- and
- an apparatus for demolding the hardened cementitious products from said flexible mold comprising:
- a conveyor for conveying said flexible mold with a front face down;
- a clamp for clamping a portion of said perimeter;
- a holding member for engaging said mold rear side;
- a movable member for moving said clamp and said clamped portion of said mold upwardly causing said mold to curve about said holding member thereby disengaging said flexible mold from the cementitious material;
- and
- wherein said conveyor comprises an upstream surface and a downstream surface, said downstream surface being slightly lower than said upstream surface so as to provide a space between said perimeter of said mold and said downstream surface thereby allowing for said clamp to engage said perimeter.
