The invention relates to a press for a casting machine and a casting machine with such a press. The press has a baseplate, an upper frame and a movable clamping platen, with two front columns and two rear columns arranged at the corner zones of the plates and at the corner zones of the upper frame. These columns extend through suitable through openings in the movable clamping platen and are fixed to the baseplate at the stationary upper frame. The press is characterized in that the front columns have a greater distance from one another than the rear columns. Because of this, essentially wider or longer permanent molds or those with side-protruding slides, up to a width corresponding to the increased distance apart of the front columns, may be inserted into the area between the baseplates and the movable clamping platen, and removed again. This means that better use can be made of the pressure and pressing capacity of the press, while the press is similarly or comparably simple, stable and compact in design and as advantageous for production and maintenance as conventional presses with columns arranged in a rectangle.

Disclosure provides a two-segment electromagnet stirring member, and a two-segment electromagnet semi-solid die-casting apparatus including the same, and a die-casting method using the same. The two-segment electromagnet stirring member includes a plurality of magnetic field generation parts therein, and includes a first electromagnetic stirring part and a second electromagnetic stirring part separated from each other. The first electromagnetic stirring part and the second electromagnetic stirring part are coupled to each other in a ring shape to surround an outer circumferential surface of a sleeve to perform electromagnetic stirring to molten metal in the sleeve, and are coupled to each other so as to position the plurality of magnetic field generation parts at radially equal gaps around the sleeve.

In an injection cylinder which can be connected with a plunger, the internal portion of the cylinder part is partitioned by a piston into a rod-side chamber on the side of the piston rod and a head-side chamber on the opposite side. An accumulator can supply a hydraulic fluid to the head-side chamber. A head-use pressure sensor can detect a pressure of the head-side chamber. A flow control valve can control a flow rate of the hydraulic fluid discharged from the rod-side chamber. A control device includes an OP control part which starts open control driving the flow control valve to the opening direction after the start of supply of the hydraulic fluid from the accumulator to the head-side chamber conditional on the detection pressure of the head-use pressure sensor rising up to the predetermined set value.

An apparatus and method for melting and forming metal in a vacuum environment. Metal is melted within a metal-forming apparatus and the molten metal is filled into a mold cavity. A high-level vacuum environment is created in the apparatus by drawing air from the apparatus which is sealed from atmospheric air. This makes it possible to reduce contact with air, which can improve the quality of the metal product.

Provided is a high-pressure casting method and a high-pressure casting device which are capable of safe and high-quality casting of a high-fusion-point metal having a fusion point exceeding 1000 K. After melting a casting material (1) inside a melting container (2) of cartridge type, the melting container (2) is linearly moved to pass through a guide (14) attached to a casting port bush (13) to thereby be communicated with the casting port bush (13). The melting container (2) is brought into close contact with the guide (14) and is setting to a cooling state. After the elapse of prescribed time, a plunger (50) is brought into contact with a plunger tip (4), and is immediately transferred together with a molten metal to the casting port bush (13). The molten metal is pressurized inside the casting port bush (13), and is injection-filled into a cavity (10).
