The invention relates to an apparatus for the casting of cast parts according to the permanent mold casting method comprising:

Apparatus for casting

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.

Press for a casting machine and casting machine

An apparatus for low-pressure casting includes a furnace wall bounding a furnace chamber, a melting crucible unit located in the furnace chamber, a heating device for heating the melting crucible unit, and at least one pressurizing unit for applying overpressure to the melting crucible unit. The furnace chamber in a top view has a length which is greater than its width, so that the furnace chamber has an elongated shape in a longitudinal direction, wherein preferably several riser pipes extending vertically are distributed roughly evenly over around 60% to 95% of the length in the longitudinal direction of the melting crucible or crucibles.
