Abstract

PURPOSE: To enhance the durability of wooden pattern and enable smooth and prompt releasing, by adding a specified releasing means to the wooden pattern for forming core assembled in the mold.
CONSTITUTION: In a wooden pattern 1 made by assembling wooden ribs 1a to support the mold surfaces in vertical and lateral direction, a fixed rod 4 made of round steel material or the like is penetrated throughout the whole length in the heightwise direction at a proper position, and clamps 5 are fitted in the rib penetrating parts to secure the ribs, and a hanger 2 made of steel plate or the like and with a sufficient length enough to project from the mold is integrally affixed to the upper end of the fixed rod. The cavity in the wooden pattern is filled densely with shock-resisting filler 3. An outer pattern is disposed around this wooden pattern, and main pattern, core and upper pattern are simultaneously molded with molding material 6 such as casting sand, and are hardened. When a chain hook or the like is inserted into the hole 2a in the hanger and a downward impact is applied to the handle, the wooden pattern may be drawn out easily without damage.
