Abstract:
1. An injection molding apparatus comprising: a plurality of injection molds; a plurality of mold clamping mechanisms for clamping the respective plurality of injection molds; a turntable mounted to undergo turning movement for shifting the injection molds between the mold clamping mechanisms; a single hydraulic pressure supply source for supplying mold clamping hydraulic pressure to the plurality of mold clamping mechanisms; a hydraulic-pressure-supply-destination selection section for making a hydraulic-pressure supply destination selection such that hydraulic pressure is selectively supplied from the single hydraulic pressure supply source to any one of the plurality of mold clamping mechanisms; a plurality of injecting machines provided in association with the plurality of mold clamping mechanisms for injecting resin material to the injection molds clamped by corresponding ones of the mold clamping mechanisms; and an electric power supply source or a compressed air supply source provided for supplying driving electric power or compressed air to the plurality of injecting machines; wherein one of the injecting machines is configured for injecting a thermoplastic resin, and another of the injecting machines is configured for injecting a non-thermoplastic resin.
