PANNEL BLOW MOLDING METHOD AND DEVECE

摘要

A method of molding a panel blow with a bridge and an apparatus thereof are provided to easily replace the core when the core is damaged and maximize the marketability by preventing the bridge from being exposed to the outside of the panel. A method of molding a panel blow with a bridge comprises a step of mounting a bridge core(10) to appear and disappear by a cylinder(S) at one side of forward and backward blow molds(6,7); a step of injecting the air in the parison and between the molds, and closing the molds; a step of moving the bridge core forwardly by the cylinder; a step of adhering/processing the bridge part of the parison; a step of withdrawing the bridge core by the cylinder; and a step of injecting the air into the parison when the closure of the mold is completed.
