Problems solved by technology

In addition, in the electric die-casting machine, there is also a type that uses the hydraulic pressure accumulated in the accumulator as an auxiliary power for the injection plunger. However, the hydraulic unit of this electric die-casting machine is different from that of the hydraulic die-casting machine. Compared with the existing hydraulic unit, the output is extremely low, so it cannot be shared with the core driving hydraulic unit

Abstract

[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).

Description

technical field [0001] The present invention relates to an electric die-casting machine provided with a hydraulic unit for driving a core, and more particularly to an arrangement and a mounting structure of the hydraulic unit for driving a core with respect to the electric die-casting machine. Background technique [0002] Die-casting machines cast products of specified shapes by injecting and filling molten metal materials (metal solution) such as aluminum alloys and magnesium alloys into the cavity formed on the mold. The speed and injection pressure are characterized by high levels. Therefore, in the past, the hydraulic die-casting machine that uses hydraulic pressure to drive the injection plunger and the drive of the mold opening and closing mechanism is the mainstream. An electric die-casting machine in which a motor drives an injection plunger and a mold opening and closing mechanism is also widespread (for example, refer to Patent Documents 1 and 2). [0003] Howev...
