PROBLEM TO BE SOLVED: To provide an online-blend type injection molding machine in which a reference position of thermal expansion in an injection direction is set near a connected part between an accumulator and an injection barrel of an injection device. SOLUTION: A fixed frame F1A, which is attached and fixed to a base frame BF, surrounds a rear part of the injection barrel 14C of the injection device 14, and holds it in such a manner as to be slidable in a Z-direction. An annular arm 26 is elongated from a left end surface of the fixed frame; a left end surface of the arm abuts on a right end surface of a diameter-enlarged part 22 which is formed on the injection barrel; a fixing bracket 20 abuts on a left end surface of the diameter-enlarged part; and the left end surface of the arm and the fixing bracket are fastened together by means of a fastening bolt 24 in the state of sandwiching the diameter-enlarged part. Thus, the reference position of the thermal expansion in the injection direction can be set near the connected part between the accumulator and the injection barrel; a position of the accumulator is fixed; a machine can be assembled on the basis of the position of the accumulator; and maintenance work is facilitated.
