Abstract: The horizontal type casting machine is capable of facilitating installation of a water jacket core and providing sufficient fluidity of the molten metal without generation of gas defect in casting a water-cooled type cylinder block. In the horizontal type casting machine, a cavity for the cylinder block is oriented vertically in which a cylinder bore portion of the cylinder block is positioned up and a crank chamber is positioned down. The cavity is defined by a stationary die, a movable die and movable cores. A movable slide core is provided movable relative to the movable die. When the movable slide core is moved to its retracted position, large working space is provided for installing the water jacket core at a given position. By the retracted movement of the movable slide core, large working space can be provided, thereby facilitating installation of the water jacket core. Further, since the water jacket core is set in its suspended fashion, easy positioning of the water jacket core results.
Abstract: An automatic molten metal supplying device capable of supplying the molten metal within a short period of time while maintaining accuracy in a supply amount and preventing dripping of the molten metal from a ladle and temperature decrease of the molten metal during its transferring state even if the transferred molten metal is of a small volume. A molten metal intake/discharge port is formed at a bottom portion of a ladle, and an atmosphere communication/blockage unit is provided which selectively communicates an internal space of the ladle with an atmosphere. After the molten metal is introduced into the ladle through the intake/discharge port, the space is shut off from the atmosphere. A cross-sectional area of the intake/discharge port is in a range of from 28 to 80 mm.sup.2.
Abstract: A metal mold cooling device capable of employing a cooling pipe having a small diameter insertable into a cooling hole having a small diameter, and capable of performing fine supply control of a cooling liquid to the metal mold for fine temperature control thereto. A cooling pipe is connected to a compressed air source through a pipe and a first change-over valve. Further, the pipe is connected to a branch pipe to which a second change-over valve is connected. A hermetic cooling liquid tank connected to a water source is connected to the second change-over valve. A third change-over valve is provided between the compressed air source and the cooling liquid tank so as to apply pneumatic pressure onto a surface of the cooling liquid in the cooling liquid tank. Since the cooling liquid tank is provided in addition to the water source, pneumatic pressure from the compressed air source can be utilized. The cooling liquid in the cooling liquid tank is compressed and is supplied to the cooling pipe.
Abstract: An automatic molten metal supplying device and supplying method capable of promoting discharge of molten metal retained in a ladle during pouring into an injection sleeve of a die-casting machine, and capable of preventing a residual molten metal from being suspended from the intake/discharge port. A ladle is selectively communicatable with an atmosphere by the opening/closing unit. The opening/closing unit is connected to a molten metal pressurizing mechanism 20 and a residual molten metal removing mechanism 30 through pipes. At the time of pouring, small volume or low pressure fluid is introduced into the ladle by means of the molten metal pressurizing mechanism through the opening/closing unit. After completion of the pouring, large volume or high pressure fluid is introduced into the ladle by the residual molten metal removing mechanism. Since low volume or low pressure fluid is applied into the ladle during pouring, the molten metal can be smoothly discharged from the ladle.
