PURPOSE: A bidirectional gate mold is provided to reduce the injection molding time and the inferior goods by evenly inserting the resin liquid in bidirectional to the cavity and core of a mold. CONSTITUTION: A bidirectional gate mold comprises a fixing unit(108) and a moving unit(110). The fixing unit comprises a resin injection port(118), first and second fixing unit nozzles(120,126) and a fixing unit manifold(124). The fixing unit gate(122) of the first fixing unit nozzles is communicated with a cavity(115) and the resin liquid flows to the cavity inside. The fixing unit manifold is communicated with the resin injecting port. The fixing unit manifold is formed by bypassing the space of the cavity and the resin liquid is moved. The second fixing unit nozzle selectively discharges the resin liquid passing through the fixing unit manifold. The moving unit comprises first and second moving unit nozzles(134,130) and a moving unit manifold(132).
