Abstract:
1. An injection molding system for carrying out an injection molding cycle, comprising: a plurality of sub-clamping units each being physically separate from one another and having a mold configured by a fixed mold and a movable mold and a clamping mechanism for clamping the mold with a predetermined pressure; an injection unit which produces melted resin material and injects the melted resin material into a cavity in the mold in the sub-clamping unit; a main clamping unit which clamps the mold in the sub-clamping unit as soon as the sub-clamping unit is positioned therein by a clamping pressure sufficient for the mold to receive the melted resin material from the injection unit; and a plurality of transfer mechanisms each being provided to corresponding one of said sub-clamping units to move the sub-clamping unit in a straight line direction between a predetermined location and the main clamping unit; wherein each of the sub-clamping units is moved back and forth by said transfer mechanism independently from and asynchronously with one another between the predetermined location and the main clamping unit, and wherein the sub-clamping unit comes out from the main clamping unit as soon as the cavity of the mold is filled with the melted resin material.
