Claims

[Scope of utility model registration request]

A product forming section is formed between a cavity die main body and a core die main body that is movable towards and away from the cavity die main body, and a molten resin injected from a spool provided in the cavity die main body is injected into the product forming section. In the injection mold for filling, a thin and long gate is formed between the cavity die body and the core die body, and a runner is formed to connect the gate and the spool; Injection molding characterized in that a rocking plate having a knife portion that pushes out the gate in cooperation with the cavity die body is attached to the core die body so as to rock under the pressure of a bushing rod provided on the core die body. Mold for use.
