THE OIL PRESSURE-SUPPLY EQUIPMENT AND POWER SUPPLY EQUIPMENT OF CATAPULT ROTARY TO A MOLD INSTALL

A power source and hydraulic supply apparatus of a rotary rubber injection machine is provided to minimize the exposure of a pipe and a wire to outside by embedding a hydraulic supply line and a source supply line inside a center support shaft. A power source and hydraulic supply apparatus of a rotary rubber injection machine comprises a hydraulic pressure supply device and a power supply device. The hydraulic supply device comprises a communicating groove(110), a plurality of hydraulic feeding grooves(101), a fluid pressure inducing groove(121), and a hydraulic hose(130). The communicating groove is formed at the top section of a center support shaft(10) with multi-stages. The hydraulic hose is connected by installing a rotary hydraulic distributing pipe(120). The power supply device comprises a power line penetration installation groove(210), a brush type power distribution unit(220), and a rotary cover(230). The power distribution unit is installed at the upper end of the supporting shaft. A circular electrode(222) is installed at the power portion distribution unit in multi-stages. A brush(231) is mounted on the rotary cover.
