HEATING MOLDING MACHINE

PROBLEM TO BE SOLVED: To simplify a driving constitution while enhancing productivity by utilizing a cam and eccentric mechanism by a continuous rotation of a rotary shaft in the case of bringing upper and lower molds mounted on upper and lower boards into coincidence at a position of a conveying level of a resin sheet. SOLUTION: A heating molding machine supplies a heated resin sheet S to a molding unit 2, and rises or falls the upper and lower molds 3a and 3b at a conveying level of the resin sheet S in the unit 2 to clamp the molds. The upper board 4 for fixing the mold 3a and the lower board 5 for fixing the mold 3b are vertically movably provided via a vertically guiding means 6. A horizontal shaft 9 to be driven by a drive means 11 is rotatably supported to a molding machine base 7. Cams 10 and 10 for vertically driving the board 4 are fixed to the shaft 9. An eccentric wheel 13 for vertically driving the board 4 via an eccentric bar 12 is rotatably held at the shaft 9. In this case, an eccentric drive means 14 for continuously rotatably driving the wheel 13 in a predetermined direction is coupled to the wheel 13.
