PROBLEM TO BE SOLVED: To provide a molding machine equipped with a frame light in weight, high in rigidity, and capable of easily executing necessary works.SOLUTION: A frame 1 on which a mold tightening device 2 and an injection device 3 are scheduled to be loaded is constituted by a bottom unit structure 11 and an upper unit structure 12 having a rectangular parallelepiped structure and assembled atop the bottom unit structure. The upper unit structure 12 is constituted by combining multiple longitudinal plates 124 in which window holes 124a are opened at requisite sites thereof. The bottom unit structure 11, in contrast, is formed to embody an overall frame shape by using main materials 111 consisting of two die steels arrayed in parallel to one another and horizontal rails 112 consisting of multiple die steels linking these two main materials. The horizontal rails 112 are configured at mutually opposing positions of both terminal units of the main materials 111 and portions corresponding respectively to both sides of the window holes 124a configured on the upper unit structure 12. |
