Abstract
PURPOSE: To obtain efficiently a formed article which needs not be trimmed by a method wherein plate materials cut to the shapes for single formed articles are provided previously, from which individual article is press formed.
CONSTITUTION: A plurality of plate materials A consisting of thermoplastic resin sheet previously cut to the shapes for single molded articles are stocked in a blank holder 10 in a stacked state. A delivery plate 11 for feeding the plate materials A one at a time is provided at a lower part of the holder 10 in such a manner that it can be freely retracted and projected by a cylinder mechanism 12 provided at the back thereof. The plate material A transferred on a guide rail 13 is clamped between upper and lower press frames 21, 21 and is fed to a forming machine 4 through a heating furnace 3. The forming machine 4 is provided with an upper mold 40 and a lower mold 41, and the upper mold 40 can be moved in the vertical direction by an upper cylinder mechanism 42. The lower mold 41 is so constructed that it can be split to right and left and it is opened to right and left after forming the plate material A, the formed article being dropped by blowing air.
