Abstract

PURPOSE: To prevent scratching, by a method wherein, in case two storage chambers and a partition wall, for use with an inner casing of a refrigerator, are molded monolithically, and molds for the partition wall and molds for the storage chamber are separated, female molds are formed with the their respective molds, the molds for the partition wall are removed to the left and the right side, and the molds for the storage chamber are removed backward.
CONSTITUTION: Molds 6 and 7 for storage chambers and molds 8a and 8b for partition wall mated together are set in a molder, and vacuum-molding is performed after preheating. After cooled with air, the molds 6 and 7 for storage chamber are removed backward (in the direction of an arrow mark M), and the molds 8a and 8b for partition wall are removed to the left and the right side (in the directions of arrow marks N and N'). This permits the easy formation of a large under cut 5 in a partition wall 4, and permits the prevention of scratching because an unnatural stree is not exercised when the mold is removed. No restriction is imposed on the shape of the under cut 5, and thus, the said process is suitable for a molding method for inner casings for use with a refrigerator.
