Abstract

PURPOSE:To readily take out a molded product in a sealing step by forming a cavity to which no resin is charged at the position where upper and lower dies face each other and mounting an elevationally movable exhausting rod in each cavity. CONSTITUTION:A lead frame 13 is interposed between upper and lower dies 11 and 12, resin 14 is filled in the mold, and a molded product is formed. Cavities 18, 19 are so formed in addition to the resin filling part in the dies 11, 12 as to confront each other, and exhausting rods 15, 16 are respectively mounted in the cavities 18, 19. After the resin 14 is charged and discharged, the dies 11, 12 are opened, the rods 15, 16 are moved in the direction indicated by the arrows 20, 21, the lead frame 13 is then pushed, and the molded product is removed from the mold. Thus, the operation of the rods can be readily performed, and the resin is not filled therein. Accordingly, it can prevent the production of burr at the molded product.
