Abstract: A vertical die casting machine of a vertically clamping type provided with a hydraulic piston-cylinder to actuate movable parting plates disposed between an injection sleeve and a runner hole in a stationary mold for constricting a melt passage, the parting plates defining an axial through-hole in a clamped state. The parting plates prevent a semi-solidified part of the melt "shell" formed in the sleeve before an injection operation from intruding into a die cavity with the liquid melt. In an embodiment with a narrow runner hole having a diameter smaller than that of the sleeve, the parting plates move together to shear a cold melt runner from the cold melt bisket formed in the sleeve so that a cast product may be upwardly removed from the stationary mold.

Abstract: In a die cast machine of the type wherein molten metal in a metal melting furnace is poured into an injection sleeve and the molten metal in the injection sleeve is injected into a die, a ladle having a molten metal discharge port is used to receive the molten metal from the furnace. The lower portion of the ladle is inserted into the injection sleeve. Then the port is opened to discharge the molten metal in the ladle into the injection sleeve and the ladle is continuously raised at such a speed that the level of the molten metal in the sleeve is always maintained at a level near the port.

Abstract: A vertical die casting machine comprising: a casting cylinder, pivotably mounted to a base, for activating a piston extension slidably fitted in a casting sleeve, and; a hollow block having an upper end connected to the casting sleeve and having a bore reduced at a lower end thereof through which bore the piston extension extends into the block. The block is forced to move by a ram cylinder relative to the casting cylinder. The piston extension has a radial extension in the block designed so that an engagement of the radial extension with the reduced bore end of the block causes a positional relationship between the casting sleeve and the piston extension to be maintained constant during an axial downward movement of the piston extension driven by the casting cylinder and during an axial upward movement driven by the ram cylinder.

Abstract: A pull-back ram cylinder apparatus in combination with a vertical mold clamping machine to be incorporated in a vertical molding or casting machine. The pull-back apparatus comprises a hydraulic cylinder for actuating a hollow ram. A ram extension consisting of the ram and a ram rod extending into the ram in a thread engagement is slidably fitted in the cylinder. The ram rod extends downwardly from the cylinder and is connected to a movable platen of the clamping machine carrying a movable mold. The cylinder has a lower throttle portion in which radial openings for discharging an operation oil are formed in an axially spaced arrangement. The inner diameter of the throttle portion is slightly larger than the outer diameter of the ram. The throttle portion having the axially spaced openings serves, in cooperation with the head end portion of the ram, as buffering means by which the movable mold is allowed to come into contact gently with a stationary mold.

Abstract: In a vertical die casting machine of the type wherein molten metal contained in a vertical casting sleeve located beneath a stationary platen is cast into a die cavity defined between a stationary die and a movable die urged against the stationary die, the casting sleeve is divided into an upper and a lower part. The upper casting sleeve is secured to the stationary platen in communication with the die cavity. The lower casting sleeve is normally held in vertical alignment with the upper casting sleeve but is moved to a position lateral to the stationary platen for receiving the molten metal. When the lower casting sleeve is returned to the normal vertical position it is urged against the upper casting sleeve and molten metal in the lower casting sleeve is teemed and cast into the die cavity by operating an injection plunger.
