INJECTION MEMBER ATTACHMENT STRUCTURE FOR INJECTION MOLDING MACHINE

摘要

When an injection member such as a screw injecting a molten material into a mold is attached to an injection molding machine, a buffer spacer is provided between the injection member and a power transmission member such as an injection shaft sleeve transmitting forward/backward moving power to the injection member. Then, the buffer spacer is fixed to the power transmission member by a bolt.

1. An injection member attachment structure for an injection molding machine used to attach an injection member, moving forward and backward so as to inject a molten material into a mold, to an injection molding machine, comprising:
a power transmission member transmitting forward/backward moving power to the injection member; a buffer spacer provided between a rear end surface of the injection member in the injection axis direction and an end surface of the power transmission member facing the injection member; and a regulation member regulating the movement of the buffer spacer in the injection axis direction of the injection member.
