Abstract:
A foundry die casting machine for the small and medium-scale production of metal parts, having at least two die cheek parts for receiving molten materials, wherein the die cheek parts form a cavity, a framework having a supporting wall for supporting the die cheek parts, at least one cheek-moving jack having means for supporting and displacing the die cheek parts, which permits removal of the metal parts, at least one removable coupling member, wherein an end of the coupling member is removable and directly supported by a die cheek part and the other end is removably connected to the cheek-moving jack, at least one cheek-moving jack carrier mounted on said framework, at least one hollow-formation reservation member for insertion into the cavity, at least one reservation member-moving jack having means for supporting and displacing the hollow-formation reservation member, and at least one removable reservation member-moving jack carrier, wherein an end of the latter is removably and directly supported by one of the die cheek parts, the invention being applicable to the manufacture of parts of aluminum alloy.
Abstract:
A machine for casting thin-walled large-size castings, such as panel-type parts, incorporating two leaves, one of which is fixed on a bed-plate and the other one on a movable shaft having a reversible drive, and secured on the same bed-plate. The shaft exterior is formed with a recess extending along the shaft length and further through the spacing between the leaves, the depth of the recess is adequate to accommodate the metal crust formed on the shaft surface from the moment the pouring process is started until the shaping of a piece being cast is completed; the machine leaves are provided with means for detaching and releasing the cast pieces from the half moulds.
