Apparatus and method for molding pouch

An apparatus for molding a pouch, the apparatus comprising:

• a die assembly comprising a die on which a pouch film is configured to be disposed;
• a stripper assembly configured to press and fix first and second sides of the pouch film disposed on the die;
• and
• a punch assembly comprising a punch configured to mold an electrode assembly accommodation part in the pouch film disposed on the die,
• wherein the stripper assembly comprises:
• a stripper disposed at a lower portion of the punch assembly and configured to press and fix the pouch film disposed on the die;
• a stripper driving piece provided at an upper portion of the punch assembly to provide force so that the stripper presses the pouch film;
• and
• a connection part configured to connect the stripper driving piece to the stripper so as to transmit the force,
• wherein the connection part comprises:
• two or more connection rods coupled to the stripper;
• a connection bar coupled to the stripper driving piece;
• and
• a connection piece configured to connect at least one or more connection rods of the two or more connection rods to the connection bar so as to transmit the force,
• wherein the connection bar comprises two or more insertion grooves, into which the two or more connection rods are inserted, respectively,
• wherein an empty space is formed between a bottom surface of each of the insertion grooves and each of the connection rods so that the force transmitted to the connection bar is not transmitted to the connection rod,
• wherein the connection piece is selectively disposed in at least one of the empty spaces so that the corresponding connection rod and the connection bar are connected to each other to transmit the force, and
• wherein no connection piece is disposed in at least one of the empty spaces so that the corresponding connection rod and the connection bar are not connected to each other to transmit the force.
