INJECTION MOLDING DEVICE OF BACK COVER FOR COMPUTER MONITOR IN INJECTION MOLDING MACHINE

摘要

PURPOSE: An injection molding device in an injection molding machine is provided which reduces the deformation of products and the man-hour of assembling by a monolithic component. CONSTITUTION: The injection molding device comprises a gas injection device. Particularly,a body nozzle(4) is formed in each corner of the interior of a mold(1). The device is characterized in that a predetermined resin(3) is entered through a flowing port for resin, then a nitrogen gas is injected through the body nozzle(4) to completely fill a cavity and to maintain a certain pressure with the beginning of cooling.
