ELECTRIC DIE-CASTING MACHINE WITH CORE-DRIVING HYDRAULIC UNIT

WIPO Patent Application WO/2012/063867

A1

[Problem] To provide an electric die-casting machine equipped with a core-driving hydraulic unit, the electric die-casting machine being configured in a manner such that, although the electric die-casting machine is equipped with the hydraulic unit, the electric die-casting machine does not require a large installation area and the maintainability of the electric die-casting machine is not compromised. [Solution] A suitable core-driving hydraulic unit (31) is configured by integrating together an oil tank (33), a hydraulic pump (34), a hydraulic pump-driving motor (35), an accumulator (36), an oil cooler (37), valves (38) including a solenoid directional control valve, an oil cleaner (39), an electric box (40), etc. in such a manner that such components are disposed on a base plate (32) doubling as an oil pan. The core-driving hydraulic unit (31) is affixed to a predetermined position on a main base board (2) in such a manner that the hydraulic pump (34) and the hydraulic pump-driving motor (35) are located below a mold-clamping electric servomotor (22) and the remaining components are located at a side of the mold-clamping electric servomotor (22).
