Patent ID: 7670132

Claim:
An injection molding apparatus for injection molding a component, comprising: a first mold half; a second mold half opposite to the first mold half, the first mold half and the second mold half cooperatively defining a molding cavity for molding the component, the first mold half having a through opening beneath the molding cavity; an eject pin penetrating through the first mold half and extending to the molding cavity; a buffering plate movable relative to the first mold half between a first position where the buffering plate is entirely received in the through opening and a second position where the buffering plate is located out of the through opening; a driving member inserted in the through opening, the driving member being configured for driving the buffering plate to slidably move out of the through opening; and an elongated spring member having a first end coupled to the driving member and an opposite second end coupled to the buffering plate, the elongated spring member being configured for deflecting the buffering plate to incline at an obtuse angle relative to the driving member when the buffering plate is in the second position.
