What Are The Classifications of Die-casting Molds?

Die-casting molds can be divided into various categories according to their structure and use. The following are common classifications of die-casting molds:

Classification by structure:

Cold Chamber Die: Suitable for casting high melting point metals, such as aluminum alloys, copper alloys, etc. In a cold chamber die casting machine, molten metal is fed through a nozzle into the mold cavity to be cast.

Hot Chamber Die: Suitable for casting low melting point metals, such as zinc alloy, magnesium alloy, etc. In a hot chamber die casting machine, the mold is partially immersed in molten metal, which is pushed into the mold cavity by a plunger.

Classified by use:

Stamping die (Trim Die): A die used to cut the shape of a die casting to the final size.

Hydraulic Die: A mold used to apply hydraulic pressure during the die casting process to form die castings.

Injection Die: A mold used to inject molten metal during the die casting process.

Classified by shape and function:

Single Cavity Die: A mold that can only produce one part at a time.

Multiple Cavity Die: A mold that can produce multiple identical or different parts at one time.

Runner Die: A mold used to control the path and speed of metal liquid flowing into the mold.

Core Pull Die: A mold used to extract parts with complex internal structures during the die casting process.

These classifications are only common classifications. In actual applications, die-casting molds may be customized and combined according to different production requirements.
