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 toward 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, a thin and long gate is formed between the cavity die body and the core die body, and a launch is formed to connect the gate and the spool. An injection mold characterized in that a fusing member for thermally fusing the gate is attached to the core die body so as to be movable in the approaching and separating directions.
