ABSTRACT:
A biaxial press molding system includes a cam apparatus having cams facing each other, and a biaxial press apparatus, disposed between the cams and installed to be capable of sliding contacting the cams, for forming a biaxial pressure to a molding object by converting rotational motion of the cams to linear reciprocating motion. Thus, a repulsive force generated during pressing concentrates only on the rotation shaft, so that an optimal design of the frame and a light system are possible. The upper and lower pressure continuously applied to a pressed object can be changed and the maximum pressure can be freely maintained, increased and decreased by forming upper and lower portions at the frictional surfaces of the cams facing each other. Also, a fine control of pressure is possible, the pressure can be appropriately distributed according to part of the pressed object, and mass production of accurate molding products is possible by controlling the pressing point of time.
