ABSTRACT:
An automatic molding apparatus includes a rotatable turntable which has located thereon a plurality of pattern supporting plates. A mold pattern located on at least one of the pattern supporting plates is surrounded by a flask located on the pattern supporting plate and having an open top and bottom. A movable sand adding box communicates with the top of the flask when the flask and the pattern supporting plate are moved to a feeding position beneath the sand adding box. The sand adding box has an open top and bottom to allow sand to pass therethrough and into the flask. A feeding channel beneath a sand supply includes an upper opening for allowing sand from the sand supply to enter the feeding channel. A movable plate allows sand in the feeding channel to enter the sand adding box when the movable plate is moved to an open position. After being filled with sand, the flask and sand adding box are raised to a position where a pressing plate compresses the sand in the flask. After the sand is compressed, the pattern supporting plate and flask are lowered and rotated to a clamping position. The flask and pattern supporting plate are raised again and the flask is clamped. The pattern supporting plate and mold pattern are then lowered while the flask is held in position to form a mold cavity in the shape of the mold pattern.
