Abstract
A method and apparatus for extracting a molded product wherein the molded product, specifically, a shutter molded of a synthetic resin with a very small thickness, from an injection molding die at a high speed without malfunction or deformation of the molded product. The apparatus includes as essential components an opposing pair of chucking members for supplementarily supporting a molded product in the clamped state while restrictively locating it at a predetermined position, and a suction pad located in alignment with the predetermined position of the molded product for grasping the latter by the action of suction. In an alternate embodiment, two chuck arms having respective suction pads at their ends are moved into contact with the shutter from opposite sides. With the invention the molded product can completely be extracted from an injection molding die in cooperation of the chucking members with the suction pad.
