Abstract
The preferred embodiment of the present invention is a die casting apparatus and method evidencing increased apparatus output including the ability of using multiple die tools. The invention includes an indexing assembly removably engaged with at least one die block assembly for transporting between four stations, including an injection station, a cooling station, an ejection station, and a recovery station. The injection station includes a frame, a clamp assembly attached to the frame for clamping and releasing the die block assembly, a shot sleeve assembly engaged with the die block assembly for receiving molten material, such as metal, from a furnace means and injecting the molten material into the die block assembly, and a shot cylinder releasably coupled with the shot sleeve assembly for controlling the injection of molten material. The ejection station includes an ejector lift assembly which engages the die block assembly for ejecting a finished part from the die block assembly, and the recovery station includes an ejector drop assembly which engages the die block assembly for placing a preload on the die block assembly.
