Abstract
An injection molding apparatus has at least two mold clamping mechanisms for clamping respective molds. A hydraulic pressure supply source supplies hydraulic pressure to the at least two mold clamping mechanisms to clamp the respective molds. A a hydraulic-pressure-supply-destination selection section is configured to allow hydraulic pressure from the hydraulic pressure supply source to be selectively supplied to any one of the two mold clamping mechanisms. At least two injecting machines are configured to inject resin material to the respective molds clamped by the respective two mold clamping mechanisms. A non-hydraulic power supply source drives the at least two injecting machines to inject the resin material.
Claims20
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.
An injection molding apparatus comprising:
- at least two mold clamping mechanisms for clamping respective molds;
- a hydraulic pressure supply source for supplying hydraulic pressure to the at least two mold clamping mechanisms to clamp the respective molds;
- a hydraulic-pressure-supply-destination selection section configured to allow hydraulic pressure from the hydraulic pressure supply source to be selectively supplied to any one of the two mold clamping mechanisms;
- at least two injecting machines for injecting resin material to the respective molds clamped by the respective two mold clamping mechanisms, one of the at least two injecting machines being configured for injecting a thermoplastic resin, and the other of the at least two injecting machines being configured for injecting a non-thermoplastic resin;
- and
- a non-hydraulic power supply source for driving the at least two injecting machines to inject the resin material.
An injection molding apparatus comprising:
- a first mold clamping mechanism for clamping a first mold;
- a second mold clamping mechanism for clamping a second mold;
- a single hydraulic pressure supply source for selectively supplying hydraulic pressure to the first mold clamping mechanism for performing a clamping operation to clamp the first mold and to the second mold clamping mechanism for performing a clamping operation to clamp the second mold;
- a hydraulic-pressure-supply-destination selection section for making a hydraulic-pressure supply destination selection that controls the single hydraulic pressure supply source to selectively supply hydraulic pressure to the first and second mold clamping mechanisms with a time difference therebetween so that the clamping operations for clamping the first and second molds do not overlap each other;
- a first injecting machine for injecting a thermoplastic resin to the first mold clamped by the first mold clamping mechanism;
- a second injecting machine for injecting a non-thermoplastic resin to the second mold clamped by the second mold clamping mechanism;
- and
- a non-hydraulic power supply source for driving the first injecting machine to inject the thermoplastic resin to the first mold clamped by the first mold clamping mechanism and for driving the second injecting machine to inject the non-thermoplastic resin to the second mold clamped by the second mold clamping mechanism.
