Abstract
A demolding apparatus for removing molded building products from a mold has a conveyor assembly to advance the mold in a machine direction. A removal mechanism contacts a dislodged portion of the molded building product and applies a dislodging force to the dislodged portion of the molded building product.
Claims18
A demolding apparatus for removing a molded building product from a mold comprising:
- a conveyor assembly configured to continuously advance the mold in a horizontal machine direction and then to continuously direct the mold around an upward curve, the upward curve being structured to cause the mold to follow the curve, and subsequently to direct the mold in a reverse machine direction, the conveyor assembly being structured to cause a portion of the molded building products to become dislodged as the mold moves continuously around the curve;
- and,
- a removal mechanism configured to contact the dislodged portion of the molded building product and to apply an intermittent dislodging force to the dislodged portion of the molded building product while the remainder of the molded building product remains in the mold.
A demolding apparatus for removing a molded building product from a continuous flexible mold, the demolding apparatus comprising:
- a conveyor assembly configured to carry a continuous flexible mold, the mold having mold cavities containing molded building products, the mold cavities having mold openings, the conveyor assembly being configured to carry the mold in an inverted orientation having the mold openings facing a downward direction, the conveyor assembly configured to advance the mold in a horizontal machine direction and then to direct the flexible mold around an upward curve, the upward curve being structured to cause the flexible mold to follow the curve and to cause a portion of the molded building product to become dislodged from a leading edge of the mold while the molded product is still traveling in a substantially horizontal direction, the conveyor assembly further configured to subsequently direct the mold in a reverse machine direction;
- and
- a removal mechanism mounted to apply a reciprocating downward dislodging force to the dislodged portion of the molded building product, the dislodging force being sufficient to prevent the molded building product from following the curve.
