INJECTION MOLDING MACHINE

摘要

PROBLEM TO BE SOLVED: To easily and in a short time perform mounting and dismounting of a nozzle and to prevent a resin material from being leaked between the nozzle and the nozzle mounting part. SOLUTION: A projecting part 34 for hooking which is orthogonal to the axial line of a nozzle 31 and is projecting outside from this axial line is formed on the back end part 33 of the nozzle 31 and a hooking channel 41 which can receive the projecting part 34 when the nozzle 31 is moved in its axial direction and can make the nozzle 31 rotatable around the axial line under a received condition is formed at the apex part 4 of an injection unit. In addition, a hooking member 42 which hoods the front face 40 of the projecting part 34 for hooking and prevents the nozzle 31 from moving forward when the nozzle 31 is rotated in the hooking channel 41 is provided.
