PURPOSE:To increase the resin sealing efficiency by a method wherein the total effective space of a metallic force is expanded by providing an intermediate metallic force between a top metallic force and a bottom metallic force. CONSTITUTION:One half 8 in the first cavity is formed into the bottom surface of the top metallic force 4 while the other half 34 is formed into the upper surface of the intermediate metallic force 24 besides one half 36 in the second cavity is formed into the bottom surface of the intermediate force 24 which the other half 18 is formed into the upper surface of the bottom metallic force 6. Consequently, the total effective space of the metal mold 22 can be expanded by the intermediate metallic force 24 between the top metallic force 4 and the bottom metallic force 6. Through these procedures, the resin sealing efficiency per shot can be increased. |
