    • PROBLEM TO BE SOLVED: To reduce an injection time or an injection pressure (mold clamping pressure) by simplifying the structure of the tip part of an injection cylinder and facilitating the setting of the gate position of a cavity 4. SOLUTION: In an injection molding machine, besides a main supply opening part 6 which can communicate with the injection opening part 5a of a main nozzle 5, an auxiliary supply opening part 8 which can communicate with the injection opening part 15a of a sub-nozzle 15 and communicates with the cavity 4 is formed in a mold 1. A supply arm part 11 fitted with the sub-nozzle 15 is supported rotatably by distribution blocks 7 and 9 each having a distribution path 10 communicating with the main supply opening part 6. The supply arm part 11 has a supply path 18 which makes the discharge opening part 10a of the distribution path 10 communicate with the injection opening part 15a of the sub-nozzle 15, can be deformed to change the relative position of the injection opening part 15a of the sub-nozzle 15, and is fitted with a screw fastening part positioning the sub-nozzle in the mold 1.
