ROTARY COMPRESSION MOLDING MACHINE USED FOR COMPRESSING MOLDINGS IN SMALL QUANTITY BY ADOPTING UNIT FOR SELECTIVELY CONTROLLING FIXED OR VIBRATING STATE OF MANY LOWER PISTONS

PURPOSE: A rotary compression molding machine is provided to efficiently produce many kinds of compression molding in small quantities by adopting a unit for selectively controlling the fixed or vibrating state of many lower pistons. CONSTITUTION: A rotary press molding machine comprises a rotor(10), many upper pistons upwardly and downwardly vibrating above the rotor, many lower pistons(30) upwardly and downwardly vibrating under the rotor, an upper piston press unit, a guide unit for guiding the lower pistons, a lower piston press unit, and a control unit(80) having many control members(81) installed corresponding to the lower pistons. The control members are engaged with the lower pistons correspondingly to make the lower pistons fixed or vibrating.
