PURPOSE: To enhance the productivity of a formed product by reducing production cost and maintenance cost by enabling the press forming of a polymeric material by pressure cylinders of which the number is less than the number of the forming press main bodies arranged on a turntable. CONSTITUTION: When a polymeric material is charged in the cavity of the bottom force, the rod of a pressure cylinder is extended and a slide 5 falls with the falling of a slide member by the extension of the rod to press the top force to the bottom force. Subsequenlty, when a turntable is rotated clockwise, the engaging groove 7a of the slide member 7 is detached from the disc- shaped block 11a provided to the leading end of the rod of the pressure cylinder 11 to successively move to a lower B-position, a left C-position and an upper D-position by 90 deg.. The operation of a stopper operating cylinder, the taking-out of a formed product from the forces, the cleaning of the forces, the charging of the polymeric material into the bottom force and the operation of the pressure cylinder 11 are performed. By this constitution, economically advantageous effect is obtained with respect to production cost and maintenance cost. |
