Abstract
The present invention provides a vertical molding machine whose mechanisms can be simplified and whose cost can be lowered. The vertical molding machine includes a frame; an upper platen (31) fixed to the frame and having an upper mold (41) mounted thereon; a connection member disposed in such a manner as to extend downward from the upper platen (31); a lower base member held by the connection member under the upper platen (31); a lower platen (35) disposed in a manner capable of advancing and retreating along the connection member and having a lower mold mounted thereon; and a mold-clamping drive section which advances and retreats the lower platen (35) so as to bring the lower mold in contact with the upper mold (41) or move the lower mold away from the upper mold (41) for effecting mold closing, mold clamping, and mold opening. The lower base member is moved downward by a mold-clamping force generated by the drive section at the time of mold clamping. Since the lower platen (35) is advanced and retreated so as to bring the lower mold in contact with the upper mold (41) or move the lower mold away from the upper mold (41) for effecting mold closing, mold clamping, and mold opening, there is no need to move an injection apparatus in a vertical direction.
