摘要：
A mold box for use in the molding of shell or stack molds comprises a pattern frame having internal lining strips that are detachably secured to the inner side walls of the pattern frame to constitute the sides of the molding space in the box. A movable pattern plate constitutes the bottom of the molding box and means are provided for moving the pattern plate into engagement with the lower edge of the lining strips so that the depth of the molding space in the box is determined by the width of the detachable lining strips.
