The present invention relates to a pattern mold assembly molding method for casting a temple bell. The present invention comprises an outer shape mold manufacturing step to form an outer shape mold using first casting sand and an iron template frame; a pattern mold assembly space preparation step to design and mark a part inside the outer shape mold to be applied with patterns and to cut out the marked part of the first casting sand; a pattern mold manufacturing step to manufacture a pattern mold to set up an iron frame inside the pattern mold which is inserted into a pattern mold assembly space; and a pattern mold insertion assembly step to insert the pattern mold into the pattern mold assembly space of the outer shape mold. The present invention is provided to delicately form a relief pattern for the casting of a large bell by inserting the pattern mold, which is separately manufactured by attaching and detaching the casting sand to or from the surface of a wooden pattern piece, into the outer shape mold; to facilitate the casting of a thin hull or a small gate; and to facilitate bronze casting by using natural casting sand such as sand and mud to make the mold air-permeable.
