Abstract
A molding box apparatus having a horizontal tubular body and a pair of pattern plates having pattern surfaces complementary to the mold chambers to be formed fitting in the tubular body, at least one of the pattern plates being slidable in the tubular body. The apparatus further has a well pattern provided on the pattern surface of one of the pattern plates and a runner pattern provided on the well pattern and extending from one end of the latter substantially perpendicularly to the pattern surface. The end of the runner pattern is adapted to be slidingly received by a guide hole formed in the other pattern plate. With this apparatus, it is possible to easily produce a mold part of a vertical split type flaskless mold assembly.
