Resin molding apparatus and method for manufacturing resin molded articles

Abstract

The present invention provides a resin molding device that can achieve the lifting and lowering of a movable platform with a simple structure. The resin molding apparatus includes: a main frame (20) having a bracket (25); a movable platform (31) supported by the main frame (20); a first ball screw (11) having a first gear (G1); a second ball screw (12) having a second gear (G2); a servo motor unit (15) having a drive member (18) connected to the first gear (G1) and the second gear (G2), which drives the first ball screw (11) and the second ball screw (12) to raise and lower the movable platform (31); a holding member (40) supported by the bracket (25) and holding the servo motor unit (15), which moves relative to the bracket (25) to change the positional relationship of the drive member (18) relative to the first gear (G1) and the second gear (G2); and a position adjustment mechanism (45A) for adjusting the relative position of the holding member (40) relative to the bracket (25).
